Abstract

The unit has a main portion (101) extending along a longitudinal direction (X101-X'101). An end portion (110) prolongs the main portion along the longitudinal direction, and has two contact surfaces (111, 112) separated from each other. The contact surfaces exert contact force on contact surfaces of a complementary terminal unit, where resultants of the force have components parallel to the longitudinal direction and oriented from one of the contact surfaces of the end portion towards the other contact surface. An independent claim is also included for a contact assembly comprising spacers.

Description

La présente invention concerne un ensemble de contact pour établir un contact électrique entre deux lignes électriques. Un tel ensemble de contact, comprenant au moins un premier organe terminal et au moins un deuxième organe terminal, peut être utilisé pour différentes applications. En particulier, un tel ensemble de contact peut être monté dans un boîtier destiné à raccorder plusieurs lignes électriques ou dans une cartouche spécifique destinée à raccorder deux lignes électriques.The present invention relates to a contact assembly for establishing an electrical contact between two power lines. Such a contact assembly, comprising at least a first terminal member and at least a second terminal member, can be used for different applications. In particular, such a contact assembly can be mounted in a housing for connecting several power lines or in a specific cartridge for connecting two power lines.

Un organe terminal de l'art antérieur comprend généralement une portion principale s'étendant suivant une direction longitudinale et une portion d'extrémité qui prolonge la portion principale et qui présente des surfaces de contact électrique. Un tel organe terminal est généralement en forme de douille ou de broche. Un ensemble de contact de l'art antérieur comprend généralement deux organes terminaux, tels qu'une douille et une broche. La douille et la broche ont des surfaces électriquement conductrices qui sont en contact mutuel lorsque la broche est insérée dans la douille. Dans cette configuration de contact, la douille présente des griffes ou pétales flexibles qui se referment sur la broche pour assurer le contact électrique entre surfaces conductrices respectives. En configuration de contact, les pétales de la douille exercent sur la broche des efforts exclusivement radiaux.A terminal member of the prior art generally comprises a main portion extending in a longitudinal direction and an end portion which extends the main portion and which has electrical contact surfaces. Such a terminal member is generally in the form of a socket or pin. A contact assembly of the prior art generally comprises two terminal members, such as a socket and a pin. The socket and the pin have electrically conductive surfaces that are in mutual contact when the pin is inserted into the socket. In this contact configuration, the socket has claws or flexible petals that close on the pin to ensure electrical contact between respective conductive surfaces. In the contact configuration, the petals of the bush exert on the spindle exclusively radial forces.

Un tel organe terminal de l'art antérieur ne permet pas un contact franc suivant la direction longitudinale avec un organe terminal complémentaire. De plus, les efforts exclusivement radiaux entre broche et douille ne permettent pas de garantir la continuité entre lignes électriques. Un ensemble de contact de l'art antérieur nécessite donc des pièces supplémentaires, en particulier un ressort et sa butée, de façon à exercer des efforts de cohésion mécanique entre ses organes terminaux et les autres composants de l'ensemble de contact. Cela augmente le coût, l'encombrement et les risques de défaillance d'un tel ensemble de contact. En outre, un tel jeu d'organes terminaux de l'art antérieur (broche et douille) ne permet pas de les utiliser dans un encombrement réduit.Such a terminal member of the prior art does not allow frank contact along the longitudinal direction with a complementary terminal member. In addition, the exclusively radial forces between pin and socket do not ensure continuity between power lines. A contact assembly of the prior art therefore requires additional parts, in particular a spring and its abutment, so as to exert efforts for mechanical cohesion between its end members and the other components of the contact assembly. This increases the cost, the size and the risk of failure of such a set of contact. In addition, such a set of terminal members of the prior art (pin and socket) does not allow to use them in a small footprint.

US-A-5 308 258 concerne un ensemble de contact qui comprend un connecteur destiné à être connecté à un connecteur électrique identique. Le connecteur électrique comprend quatre éléments de contact identiques reliés chacun à un câble électrique. Chaque élément de contact est composé d'une lamelle métallique formée par pliage. Cependant, cet ensemble de contact ne permet pas de guider en translation les connecteurs électriques lors de leur mise en contact, ce qui n'est pas satisfaisant. US-A-5,308,258 relates to a contact assembly which comprises a connector intended to be connected to an identical electrical connector. The electrical connector comprises four identical contact elements each connected to an electric cable. Each contact element is composed of a metal strip formed by folding. However, this contact assembly does not guide the electrical connectors in translation when they come into contact, which is not satisfactory.

La présente invention vise notamment à remédier à ces inconvénients, en proposant un organe terminal dont la structure est compacte et assure en elle-même des efforts de cohésion mécanique garantissant un contact franc entre éléments conducteurs.The present invention aims in particular to overcome these disadvantages, by providing a terminal member whose structure is compact and ensures in itself mechanical cohesion efforts ensuring a frank contact between conductive elements.

A cet effet, l'invention a pour objet un ensemble de contact, pour établir un contact électrique entre deux lignes électriques, l'ensemble de contact comprenant au moins un premier organe terminal et au moins un deuxième organe terminal reliés respectivement à chaque ligne électrique, chacun des organes terminaux comprenant :

  • au moins une portion d'extrémité prolongeant la portion principale suivant la direction longitudinale, chaque portion d'extrémité présentant au moins une première surface de contact et une deuxième surface de contact respective.
Chaque première surface de contact est située sur la partie proximale de la portion d'extrémité et chaque deuxième surface de contact est séparée de la première surface de contact respective par une distance qui est non-nulle, suivant la direction longitudinale. La première surface de contact et la deuxième surface de contact du premier organe terminal sont agencées pour exercer, respectivement sur la deuxième surface de contact et sur la première surface de contact du deuxième organe terminal, des efforts de contact dont chaque résultante a une composante parallèle à la direction longitudinale et orientée de la première surface de contact respective vers la deuxième surface de contact respective. Chaque organe terminal a une section creuse qui s'étend sur au moins une partie de sa longueur suivant la direction longitudinale et qui débouche à l'extrémité distale de la portion d'extrémité respective. L'ensemble de contact comprend en outre une tige insérée dans la section creuse de l'un des organes terminaux, une partie distale de la tige dépassant de la portion d'extrémité correspondante de façon à permettre le guidage en translation des organes terminaux lors de leur mise en contact.For this purpose, the subject of the invention is a contact assembly for establishing an electrical contact between two electrical lines, the contact assembly comprising at least a first terminal member and at least a second terminal member respectively connected to each electrical line. each of the terminal members comprising:

La figure 1 illustre un boîtier 2 pour raccorder des lignes électriques entre elles, telles que les lignes électriques 10 et 20 dont l'enveloppe est représentée en traits mixtes à la figure 1. Le boîtier 2 est équipé d'au moins un ensemble de contact 1 qui est logé dans un alésage cylindrique 3 du boîtier 2. L'ensemble de contact 1 permet de raccorder les lignes électriques 10 et 20. Ainsi, l'ensemble de contact 1 peut par exemple définir les contacts centraux d'un connecteur coaxial ou d'une liaison coaxiale. Le boîtier 2 forme le contact de masse de cette liaison coaxiale. Une telle liaison coaxiale remplit la fonction de guide d'ondes en hyperfréquence.The figure 1 illustrates a housing 2 for connecting electrical lines to each other, such as the power lines 10 and 20 whose envelope is shown in phantom at the figure 1 . The housing 2 is equipped with at least one contact assembly 1 which is housed in a cylindrical bore 3 of the housing 2. The contact assembly 1 makes it possible to connect the electrical lines 10 and 20. Thus, the contact assembly 1 can for example define the central contacts of a coaxial connector or a coaxial connection. The housing 2 forms the ground contact of this coaxial connection.

La figure 2 illustre les différents composants de l'ensemble de contact 1. L'ensemble de contact 1 comprend un premier organe terminal 100 et un deuxième organe terminal 200. En fonctionnement, lorsque l'ensemble de contact 1 raccorde entre elles les lignes électriques 10 et 20, le premier organe terminal 100 et le deuxième organe terminal 200 sont reliés respectivement à chaque ligne électrique 10 et 20.The figure 2 illustrates the different components of the contact assembly 1. The contact assembly 1 comprises a first terminal member 100 and a second terminal member 200. In operation, when the contact assembly 1 connects the electrical lines 10 and 20 together. the first terminal member 100 and the second end member 200 are respectively connected to each electrical line 10 and 20.

La figure 3 montre l'organe terminal 100 qui comprend une portion principale 101 et une portion d'extrémité 110. La portion principale 101 s'étend globalement suivant une direction longitudinale X101-X'101. La portion d'extrémité 110 prolonge la portion principale 101 suivant la direction longitudinale X101-X'101. Dans l'exemple des figures, la portion principale 101 et la portion d'extrémité 110 sont directement liées et solidaires entre elles. Plus précisément, la portion principale 101 est monobloc avec la portion d'extrémité 110.The figure 3 shows the end member 100 which comprises a main portion 101 and an end portion 110. The main portion 101 extends generally in a longitudinal direction X101-X'101. The end portion 110 extends the main portion 101 in the longitudinal direction X101-X'101. In the example of the figures, the main portion 101 and the end portion 110 are directly connected and integral with each other. More specifically, the main portion 101 is integral with the end portion 110.

Dans la présente demande, l'adjectif « longitudinal » qualifie une direction ou un élément qui s'étend suivant la direction longitudinale X101-X'101 ou parallèlement à celle-ci. La direction longitudinale X101-X'101 forme une direction principale de la portion principale 101 et, par extension, de l'organe terminal 100.In the present application, the term "longitudinal" qualifies a direction or an element which extends in the longitudinal direction X101-X'101 or parallel thereto. The longitudinal direction X101-X'101 forms a principal direction of the main portion 101 and, by extension, of the end member 100.

La portion principale 101 présente une partie proximale 102 et une partie distale 103. La portion d'extrémité 110 présente une partie proximale 113, une partie distale 114 et une partie médiane 116. Pour la portion d'extrémité 110, la partie médiane 116 s'étend entre la partie proximale 113 et la partie distale 114. La partie proximale 113 de la portion d'extrémité 110 jouxte la partie distale 103 de la portion principale 101.The main portion 101 has a proximal portion 102 and a distal portion 103. The end portion 110 has a proximal portion 113, a distal portion 114 and a medial portion 116. For the end portion 110, the medial portion 116 s extends between the proximal portion 113 and the distal portion 114. The proximal portion 113 of the end portion 110 abuts the distal portion 103 of the main portion 101.

Dans la présente demande, les adjectifs « proximal » et « distal » sont employés par référence à la distance relative entre un élément et la ligne électrique 10 ou 20 à laquelle cet élément est destiné à être connecté. Dans l'état raccordé illustré à la figure 1, la partie proximale 102 de la portion principale 101 est relativement proche de la ligne électrique 10, tandis que la partie distale 103 en est relativement éloignée.In the present application, the adjectives "proximal" and "distal" are used with reference to the relative distance between an element and the electrical line 10 or 20 to which this element is intended to be connected. In the connected state illustrated in figure 1 , the proximal portion 102 of the main portion 101 is relatively close to the power line 10, while the distal portion 103 is relatively remote.

La portion principale 101 a une surface externe 106 qui est cylindrique à base circulaire. De plus, l'organe terminal 100 a une section creuse 105 qui s'étend sur une partie de la longueur L100 de l'organe terminal 100. En l'occurrence, la section creuse 105 est creuse sur toute la portion principale 101. En d'autres termes, la portion principale 101 est un tube à base circulaire dont l'axe est la direction longitudinale X101-X'101. La section creuse 105 débouche à l'extrémité distale de la portion d'extrémité 110. Dans la présente demande, le terme « longueur » est employé par référence à la direction longitudinale X101-X'101 d'un organe terminal 100 ou 200.The main portion 101 has an outer surface 106 which is cylindrical with a circular base. In addition, the end member 100 has a hollow section 105 which extends over a portion of the length L100 of the end member 100. In this case, the hollow section 105 is hollow over the entire main portion 101. in other words, the main portion 101 is a circular base tube whose axis is the longitudinal direction X101-X'101. The hollow section 105 opens at the distal end of the end portion 110. In the present application, the term "length" is used with reference to the longitudinal direction X101-X'101 of a terminal member 100 or 200.

Comme le montre la figure 1, l'ensemble de contact 1 comprend en outre une tige 150 qui est insérée dans la section creuse 105 de l'organe terminal 100, comme cela est visible aux figures 4 à 10. Une partie distale 151 de la tige 150 dépasse de la portion d'extrémité 110 de façon à permettre le guidage en translation des organes terminaux 100 et 200 lors de leur mise en contact.As shown in figure 1 the contact assembly 1 further comprises a rod 150 which is inserted into the hollow section 105 of the end member 100, as can be seen in FIGS. Figures 4 to 10 . A distal portion 151 of the rod 150 protrudes from the end portion 110 so as to allow the translational guidance of the end members 100 and 200 when they come into contact.

La portion d'extrémité 110 présente, dans un plan P100 orthogonal à la direction longitudinale X101-X'101, une section transversale 115, en forme de « C », qui est moins étendue que la section creuse 105 de la portion principale 101. En l'occurrence, la portion d'extrémité 110 est obtenue par une découpe ou un usinage du tube formant la portion principale 101.The end portion 110 has, in a plane P100 orthogonal to the longitudinal direction X101-X'101, a cross section 115, in the form of "C", which is less extensive than the hollow section 105 of the main portion 101. In this case, the end portion 110 is obtained by cutting or machining the tube forming the main portion 101.

La portion d'extrémité 110 présente une première surface de contact 111 et une deuxième surface de contact 112. La première surface de contact 111 est située sur la partie proximale 113 de la portion d'extrémité 110. La deuxième surface de contact 112 est située sur la partie distale 114 de la portion d'extrémité 110. La deuxième surface de contact 112 est séparée de la première surface de contact 111 par une distance D11.12 qui est non nulle et qui s'étend suivant la direction longitudinale X101-X'101. Une surface de jonction 117 s'étend entre la première surface de contact 111 et la deuxième surface de contact 112.The end portion 110 has a first contact surface 111 and a second contact surface 112. The first contact surface 111 is located on the proximal portion 113 of the end portion 110. The second contact surface 112 is located on the distal portion 114 of the end portion 110. The second contact surface 112 is separated from the first contact surface 111 by a distance D11.12 which is non-zero and which extends in the longitudinal direction X101-X '101. A junction surface 117 extends between the first contact surface 111 and the second contact surface 112.

Comme le montrent les figures 3 et 9, la première surface de contact 111 et la deuxième surface de contact 112 sont obliques par rapport à la direction longitudinale X101-X'101. Dans le cas où la première surface de contact 111 et la deuxième surface de contact 112 sont planes, comme dans l'exemple des figures, le terme « oblique » signifie que les plans respectifs de la première surface de contact 111 et de la deuxième surface de contact 112 sont inclinées sur la direction longitudinale X101-X'101. Dans le cas ou la première surface de contact ou la deuxième surface de contact est courbe, le terme « oblique » signifie qu'un plan tangent à une région médiane de la première surface de contact ou de la deuxième surface de contact est incliné sur la direction longitudinale.As shown by figures 3 and 9 the first contact surface 111 and the second contact surface 112 are oblique with respect to the longitudinal direction X101-X'101. In the case where the first contact surface 111 and the second contact surface 112 are planar, as in the example of the figures, the term "oblique" means that the respective planes of the first contact surface 111 and the second surface contact 112 are inclined on the longitudinal direction X101-X'101. In the case where the first contact surface or the second contact surface is curved, the term "oblique" means that a plane tangential to a median region of the first contact surface or the second contact surface is inclined on the longitudinal direction.

Comme le montre la figure 9, l'intersection entre, d'une part, un plan P11.12 qui comprend la direction longitudinale X101-X'101 et qui est transversal à la première surface de contact 111 ainsi qu'à la deuxième surface de contact 112 et, d'autre part, un plan P111 tangent à la première surface de contact 111 définit une droite L111 qui forme avec la direction longitudinale X101-X'101 un angle A111, valant environ 30°. L'angle A111 est mesuré dans le sens trigonométrique à partir de la direction longitudinale X101-X'101. L'angle A111 peut être compris entre 10° et 90°. Le plan P11.12 correspond au plan de la figure 9.As shown in figure 9 , the intersection between, on the one hand, a plane P11.12 which comprises the longitudinal direction X101-X'101 and which is transverse to the first contact surface 111 and to the second contact surface 112 and, d on the other hand, a plane P111 tangential to the first contact surface 111 defines a line L111 which forms with the longitudinal direction X101-X'101 an angle A111, equal to approximately 30 °. Angle A111 is measured in the trigonometric direction from the longitudinal direction X101-X'101. The angle A111 can be between 10 ° and 90 °. Plan P11.12 corresponds to the plan of the figure 9 .

L'intersection entre, d'une part, le plan P11.12 et, d'autre part, un plan P112 tangent à la deuxième surface de contact 112 définit une droite L112 qui forme avec la direction longitudinale X101-X'101 un angle A112, valant environ 30°. L'angle A112 est mesuré dans le sens trigonométrique à partir de la direction longitudinale X101-X'101. L'angle A112 peut être compris entre 10° et 90°. La surface de jonction 117 est inclinée sur la direction longitudinale X101-X'101 suivant un angle inférieur aux angles A111 et A112.The intersection between, on the one hand, the plane P11.12 and, on the other hand, a plane P112 tangential to the second contact surface 112 defines a line L112 which forms with the longitudinal direction X101-X'101 an angle A112, worth about 30 °. Angle A112 is measured in the trigonometric direction from the longitudinal direction X101-X'101. The angle A112 can be between 10 ° and 90 °. The junction surface 117 is inclined in the longitudinal direction X101-X'101 at an angle less than angles A111 and A112.

Dans l'exemple des figures, les angles A111 et A112 sont approximativement égaux, car ils sont opposés par le sommet. Les angles A111 et A112 sont déterminées en fonction du coefficient de frottement des matériaux formant les organes terminaux 100 et 200.In the example of the figures, the angles A111 and A112 are approximately equal because they are opposed by the vertex. The angles A111 and A112 are determined as a function of the coefficient of friction of the materials forming the end members 100 and 200.

L'organe terminal 200 a une forme semblable à la forme de l'organe terminal 100. La description de l'organe terminal 100 donné ci-avant en relation avec les figures 2 à 10 peut donc être transposée à l'organe terminal 200, à l'exception des différences ressortant ci-après. Un élément de l'organe terminal 200 identique ou correspondant à un élément de l'organe terminal 100 porte la même référence numérique augmentée de 100.The terminal member 200 has a shape similar to the shape of the terminal member 100. The description of the terminal member 100 given above in relation to the Figures 2 to 10 can therefore be transposed to the terminal member 200, with the exception of the differences shown below. An element of the terminal member 200 identical or corresponding to an element of the terminal member 100 has the same numerical reference increased by 100.

On définit ainsi une portion principale 201, une partie proximale 202, une partie distale 203, une portion d'extrémité 210, une première surface de contact 211, une deuxième surface de contact 212, une partie proximale 213 de la portion d'extrémité 210, une partie distale 214 de la portion d'extrémité 210.A main portion 201, a proximal portion 202, a distal portion 203, an end portion 210, a first contact surface 211, a second contact surface 212, a proximal portion 213 of the end portion 210 are thus defined. , a distal portion 214 of the end portion 210.

A l'instar de l'organe terminal 100, la deuxième surface de contact 212 de l'organe terminal 200 est séparée de la première surface de contact 211, suivant la direction longitudinale X101-X'101, par une distance D12.11 non-nulle et matérialisée à la figure 9. De plus, la distance D12.11 est sensiblement égale à la distance D11.12. Ainsi, l'organe terminal 200 a une forme complémentaire à la forme de l'organe terminal 100.Like the end member 100, the second contact surface 212 of the end member 200 is separated from the first contact surface 211, in the longitudinal direction X101-X'101, by a distance D12.11. -nulle and materialized at the figure 9 . In addition, the distance D12.11 is substantially equal to the distance D11.12. Thus, the terminal member 200 has a shape complementary to the shape of the terminal member 100.

Comme le montrent les figures 8 et 10, la première surface de contact 111 du premier organe terminal 100 est agencée pour exercer sur la deuxième surface de contact 212 du deuxième organe terminal 200 des efforts de contact dont la résultante est symbolisée par une flèche F111 aux figures 8 à 10. Les efforts de contact peuvent être des efforts linéiques ou des efforts surfaciques en fonction des formes des surfaces en contact. La résultante F111 a une composante F111X qui est parallèle à la direction longitudinale X101-X'101 et qui est orientée de la première surface de contact 111 vers la deuxième surface de contact 112.As shown by figures 8 and 10 , the first contact surface 111 of the first end member 100 is arranged to exert on the second contact surface 212 of the second end member 200 contact forces whose resultant is symbolized by an arrow F111 to Figures 8 to 10 . The contact forces may be linear forces or surface forces depending on the shapes of the surfaces in contact. The resultant F111 has a component F111X which is parallel to the longitudinal direction X101-X'101 and which is oriented from the first contact surface 111 to the second contact surface 112.

Suivant une direction radiale, la résultante F111 a une composante radiale F111 Y qui garantit une pression radiale entre les organes terminaux 100 et 200. Dans la présente demande, une direction radiale est une direction perpendiculaire et sécante à la direction longitudinale X101-X'101, telle que la direction Y101-Y'101. L'adjectif « radial » est employé ici par référence à la géométrie globalement cylindrique de l'organe terminal 100 ou 200. Dans la mesure où l'organe terminal 100 ou 200 présente cette géométrie cylindrique, la direction longitudinale X101-X'101 est confondue avec l'axe de la surface externe 106 cylindrique de la portion principale 101.In a radial direction, the resultant F111 has a radial component F111 Y which guarantees a radial pressure between the end members 100 and 200. In the present application, a radial direction is a direction perpendicular and secant to the longitudinal direction X101-X'101 , such as the direction Y101-Y'101. The adjective "radial" is used here with reference to the generally cylindrical geometry of the terminal member 100 or 200. Insofar as the terminal member 100 or 200 has this cylindrical geometry, the longitudinal direction X101-X'101 is merged with the axis of the cylindrical outer surface 106 of the main portion 101.

De même, la deuxième surface de contact 112 du premier organe terminal 100 est agencée pour exercer sur la première surface de contact 211 du deuxième organe terminal 200 des efforts de contact dont la résultante est symbolisée par une flèche F112 aux figures 8 et 10. La résultante F112 a une composante F112X qui est parallèle à la direction longitudinale X101-X'101 et qui est orientée de la première surface de contact 111 vers la deuxième surface de contact 212. La résultante F112 a une composante radiale F112Y qui garantit une pression radiale entre les organes terminaux 100 et 200.Similarly, the second contact surface 112 of the first end member 100 is arranged to exert on the first contact surface 211 of the second end member 200 contact forces whose resultant is symbolized by an arrow F112 to figures 8 and 10 . The resultant F112 has a component F112X which is parallel to the longitudinal direction X101-X'101 and which is oriented from the first contact surface 111 to the second contact surface 212. The resultant F112 has a radial component F112Y which guarantees a pressure radial between the end members 100 and 200.

En d'autres termes, la première surface de contact 111 et la deuxième surface de contact 112 du premier organe terminal 100 sont agencées pour exercer, respectivement sur la deuxième surface de contact 212 et sur la première surface de contact 211 de l'organe terminal 200 complémentaire, des efforts de contact dont chaque résultante F111 ou F112 a une composante F111X ou F112X qui est parallèle à la direction longitudinale X101-X-101 et qui orientée de la première surface de contact 111 vers la deuxième surface de contact 112. L'orientation d'une composante dite « longitudinale », telle que les composantes F111X et F112X, est donc orientée depuis une zone dite proximale vers une zone distale.In other words, the first contact surface 111 and the second contact surface 112 of the first end member 100 are arranged to exert respectively on the second contact surface 212 and on the first contact surface 211 of the end member 200 complementary, contact forces of which each resultant F111 or F112 has a component F111X or F112X which is parallel to the longitudinal direction X101-X-101 and which is oriented from the first contact surface 111 to the second contact surface 112. L The orientation of a so-called "longitudinal" component, such as the components F111X and F112X, is therefore oriented from a so-called proximal zone to a distal zone.

Les composantes longitudinales F111X et F112X et les composantes radiales F111Y et F112Y permettent de garantir un contact franc, suivant la direction longitudinale X101-X'101, entre les surfaces de contact respectives 111, 112, 211, 212 du premier organe terminal 100 et du deuxième organe terminal 200.The longitudinal components F111X and F112X and the radial components F111Y and F112Y make it possible to guarantee a free contact, in the longitudinal direction X101-X'101, between the respective contact surfaces 111, 112, 211, 212 of the first end member 100 and the second terminal organ 200.

Lors de la mise en contact de l'organe terminal 100 avec l'organe terminal 200, un opérateur ou un dispositif pousse les lignes électriques 10 et 20 vers les organes terminaux 100 et 200. Cette poussée est symbolisée aux figures 7, 8 et 10 par deux forces F10 et F20 qui sont concourantes à la direction longitudinale X101-X'101 et qui sont orientées l'une vers l'autre.During the contacting of the terminal member 100 with the terminal member 200, an operator or a device pushes the electrical lines 10 and 20 to the terminal members 100 and 200. This thrust is symbolized in FIGS. Figures 7, 8 and 10 by two forces F10 and F20 which are concurrent to the longitudinal direction X101-X'101 and which are oriented towards one another.

A l'équilibre, les forces F10 et F20 sont d'égales intensités. La force F10 est transmise à l'organe terminal 200 par l'organe 100 et, réciproquement, la force F20 est transmise à l'organe terminal 100 par l'organe 200. La force F10 induit la résultante F111 au niveau de la première surface de contact 111 et la résultante F112 au niveau de la deuxième surface de contact 112. Les résultantes F111 et F112 sont orientées respectivement vers la deuxième surface de contact 212 et vers la première surface de contact 211 de l'organe terminal 200. Les composantes longitudinales F111 X et F112X sont donc orientées sensiblement de l'organe terminal 100 vers l'organe terminal 200.At equilibrium, the forces F10 and F20 are of equal intensity. The force F10 is transmitted to the terminal member 200 by the member 100 and, conversely, the force F20 is transmitted to the terminal member 100 by the member 200. The force F10 induces the resultant F111 at the first surface contact 111 and the resultant F112 at the second contact surface 112. The resultants F111 and F112 are respectively oriented towards the second contact surface 212 and towards the first contact surface 211 of the terminal member 200. The longitudinal components F111 X and F112X are oriented substantially from the terminal member 100 to the terminal member 200.

De façon symétrique, la première surface de contact 211 et la deuxième surface de contact 212 du deuxième organe terminal 200 exercent des efforts de contact respectivement sur la deuxième surface de contact 112 et la première surface de contact 111 du premier organe terminal 100. En d'autres termes, la force F20 induit deux résultantes, non représentées, au niveau de la première surface de contact 211 et de la deuxième surface de contact 212 de l'organe terminal 200. Ces résultantes sont orientées respectivement vers la deuxième surface de contact 112 et vers la première surface de contact 111 de l'organe terminal 100. Les composantes longitudinales, non représentées, de ces résultantes sont donc orientées sensiblement de l'organe terminal 200 vers l'organe terminal 100.In a symmetrical manner, the first contact surface 211 and the second contact surface 212 of the second end member 200 exert contact forces respectively on the second contact surface 112 and the first contact surface 111 of the first terminal member 100. In other words, the force F20 induces two resultants, not shown, at the level of the first contact surface 211 and the second contact surface 212 of the terminal member 200. These results are respectively oriented towards the second contact surface 112. and to the first contact surface 111 of the terminal member 100. The longitudinal components, not shown, of these results are therefore oriented substantially from the terminal member 200 to the terminal member 100.

A l'équilibre, les composantes longitudinales des efforts de contact compensent les forces de poussée F10 et F20. Les composantes radiales des efforts de contact se compensent mutuellement. Ainsi, l'ensemble de contact 1 sous contrainte se trouve à l'équilibre.At equilibrium, the longitudinal components of the contact forces compensate for the thrust forces F10 and F20. The radial components of the contact forces compensate each other. Thus, the contact assembly 1 under stress is in equilibrium.

Les composantes longitudinales et radiales des résultantes, non représentées, des efforts de contact qu'exerce l'organe terminal 200 sur l'organe terminal 100 contribuent aussi à garantir un contact franc entre les surfaces de contact respectives 111, 112, 211, 212 du premier organe terminal 100 et du deuxième organe terminal 200.The longitudinal and radial components of the results, not shown, of the contact forces exerted by the end member 200 on the end member 100 also contribute to guaranteeing a frank contact between the respective contact surfaces 111, 112, 211, 212 of the first terminal member 100 and the second terminal member 200.

La portion d'extrémité 110 est flexible. De plus, la portion d'extrémité 110, comme la portion principale 101, est constituée d'un matériau relativement élastique, par exemple un alliage de cuivre au béryllium (CuBe2). La portion d'extrémité 110 peut ainsi se déformer sous l'effet des résultantes F111 et F112, lorsque les organes terminaux 100 et 200 sont mis en contact et soumis aux forces F10 et F20, comme cela ressort de la comparaison entre les figures 6, 7 et 8 ou 9 et 10.The end portion 110 is flexible. In addition, the end portion 110, like the main portion 101, is made of a relatively elastic material, for example a beryllium copper alloy (CuBe2). The end portion 110 can thus be deformed under the effect of the resultants F111 and F112, when the end members 100 and 200 are brought into contact and subjected to the forces F10 and F20, as is apparent from the comparison between the Figures 6, 7 and 8 or 9 and 10 .

Comme le montrent les figures 2, 4, 5 et 6 à 8, l'ensemble de contact 1 comprend en outre deux entretoises 11 et 21 qui sont électriquement isolantes. Les entretoises 11 et 21 sont identiques dans l'exemple des figures. L'entretoise 11 a une forme de manchon qui présente une surface externe cylindrique et un alésage central qui est coaxial à la surface externe de l'entretoise 11. La longueur de l'entretoise 11 suivant la direction longitudinale X101-X'101 est relativement faible devant la longueur L100 du premier organe terminal 100.As shown by figures 2 , 4 , 5 and 6 to 8 , the contact assembly 1 further comprises two spacers 11 and 21 which are electrically insulating. The spacers 11 and 21 are identical in the example of the figures. The spacer 11 has a sleeve shape which has a cylindrical outer surface and a central bore which is coaxial with the outer surface of the spacer 11. The length of the spacer 11 in the longitudinal direction X101-X'101 is relatively low in front of the length L100 of the first terminal member 100.

L'entretoise 11 est montée sur un embout proximal 152 de la tige 150. L'embout proximal 152 présente une collerette 153 pour maintenir en position l'entretoise 11. De façon similaire, l'entretoise 21 est montée sur un embout proximal 252 du deuxième organe terminal 200. L'embout proximal 252 présente une collerette 253 pour maintenir en position l'entretoise 21.The spacer 11 is mounted on a proximal end 152 of the rod 150. The proximal end 152 has a flange 153 for holding the spacer 11 in position. similarly, the spacer 21 is mounted on a proximal endpiece 252 of the second end member 200. The proximal endpiece 252 has a flange 253 for holding the spacer 21 in position.

Les embouts proximaux 152 et 252 sont monoblocs respectivement avec la tige 150 et avec le deuxième organe terminal 200. Dans la mesure où la tige 150 et le deuxième organe terminal 200 sont conducteurs, les embouts proximaux 152 et 252 sont aussi conducteurs.The proximal endpieces 152 and 252 are integral with the rod 150 and the second end member 200 respectively. Since the rod 150 and the second end member 200 are conductive, the proximal endpieces 152 and 252 are also conductive.

Après leurs assemblages, les entretoises 11 et 21 permettent de maintenir en position les organes terminaux 100 et 200 et d'isoler électriquement les organes terminaux 100 et 200 du boîtier 2, comme le montrent les figures 1 ou 6 à 8.After their assemblies, the spacers 11 and 21 make it possible to hold the end members 100 and 200 in position and to electrically isolate the terminal members 100 and 200 of the casing 2, as shown by the figures 1 or 6 to 8 .

Pour remplir les fonctions d'isolation électrique et de maintien en position, chaque entretoise 11 ou 21 présente une section transversale, dans le plan P100, qui est plus étendu que la section transversale du premier organe terminal 100 ou du deuxième organe terminal 200. Dans l'exemple des figures, les entretoises 11 et 21 ont des diamètres D11 et D21 respectifs qui sont supérieurs au diamètre D100 et équivalent du premier organe terminal 100 et du deuxième organe terminal 200.In order to fulfill the functions of electrical isolation and of holding in position, each spacer 11 or 21 has a cross section, in the plane P100, which is larger than the cross section of the first terminal member 100 or the second terminal member 200. In the example of the figures, the spacers 11 and 21 have respective diameters D11 and D21 which are greater than the diameter D100 and equivalent of the first end member 100 and the second end member 200.

Les entretoises 11 et 21 sont agencées par rapport à l'organe terminal correspondant 100 ou 200 de sorte qu'un élément conducteur 154 ou 254 électriquement relié ou appartenant à un organe terminal respectif 100 ou 200 est accessible depuis un côté 11.5 ou 21.5 de l'entretoise respective 11 ou 21 qui est opposé à la portion d'extrémité respective 110 ou 210. Les éléments conducteurs 154 et 254 forment en quelque sorte des saillies conductrices sur les faces opposées de l'ensemble de contact 1. En d'autres termes, les entretoises 11 et 21 autorisent des contacts électriques suivant la direction longitudinale X101-X'101 entre l'ensemble de contact 1 et les extrémités des lignes électriques 10 et 20. Alternativement, l'élément conducteur 154 ou 254 pourrait être renfoncé au sein de l'entretoise respective 11 ou 21 de façon à coopérer avec un organe complémentaire formant saillie à l'extrémité de la ligne électrique 10 ou 20 correspondante.The spacers 11 and 21 are arranged relative to the corresponding terminal member 100 or 200 so that a conductive element 154 or 254 electrically connected to or belonging to a respective terminal member 100 or 200 is accessible from a side 11.5 or 21.5 of the respective spacer 11 or 21 which is opposed to the respective end portion 110 or 210. The conductive elements 154 and 254 form somehow conductive projections on the opposite faces of the contact assembly 1. In other words , the spacers 11 and 21 allow electrical contacts in the longitudinal direction X101-X'101 between the contact assembly 1 and the ends of the power lines 10 and 20. Alternatively, the conductive element 154 or 254 could be recessed within the respective spacer 11 or 21 so as to cooperate with a complementary member projecting at the end of the corresponding power line 10 or 20.

Dans l'état déconnecté illustré à la figure 6, dans lequel les surfaces de contact 111 et 112 d'une part, et 211 et 212 d'autre part, ne sont pas mises en contact, les éléments conducteurs 154 et 254 dépassent hors de l'alésage cylindrique 3 respectivement d'une longueur L154 et d'une longueur L254. Lorsqu'un opérateur appuie, au moyen des extrémités des lignes électriques 10 et 20, sur les éléments conducteurs 154 et 254 pour repousser les organes terminaux 100 et 200 l'un vers l'autre suivant les flèches X100 et X200 à la figure 4, les entretoises 11 et 21 coulissent dans l'alésage cylindrique 3.In the disconnected state shown in figure 6 , in which the contact surfaces 111 and 112 on the one hand, and 211 and 212 on the other hand, are not brought into contact, the conductive elements 154 and 254 project out of the cylindrical bore 3 respectively by a length L154 and a length L254. When an operator presses, by means of the ends of the power lines 10 and 20, on the conductive elements 154 and 254 to push the end members 100 and 200 towards each other according to the arrows X100 and X200 at the figure 4 the spacers 11 and 21 slide in the cylindrical bore 3.

Sous l'effet de ces poussées, l'ensemble de contact 1 se trouve dans l'état illustré à la figure 7, dans lequel les surfaces de contact 111 et 112 d'une part, et 211 et 212 d'autre part, sont mises en contact franc. Les portions d'extrémité 110 et 210 fléchissent et exercent alors des efforts de contact sur les surfaces de contact 111, 112, 211 et 212. Dans l'état de la figure 7, les organes terminaux 100 et 200 assurent une conduction électrique optimale, les éléments des organes terminaux 100 et 200 étant placés à leurs cotes nominales.Under the effect of these thrusts, the contact assembly 1 is in the state shown in FIG. figure 7 , in which the contact surfaces 111 and 112 on the one hand, and 211 and 212 on the other hand, are brought into open contact. The end portions 110 and 210 flex and then exert contact forces on the contact surfaces 111, 112, 211 and 212. In the state of the figure 7 , the end members 100 and 200 provide optimum electrical conduction, the elements of the end members 100 and 200 being placed at their nominal dimensions.

Dans l'état conducteur illustré à la figure 8, l'ensemble de contact 1 assure aussi la conduction électrique entre les lignes électriques 10 et 20. Le contact franc entre les organes terminaux 100 et 200 est également assuré dans l'état conducteur de la figure 8. Dans cet état conducteur, les forces de poussée des organes terminaux 100 et 200 l'un vers l'autre sont supérieures à celles exercées dans l'état conducteur illustré à la figure 7. Ces poussées supérieures induisent des flèches plus grandes au niveau des parties distales respectives 114 et 214 des portions d'extrémité 110 et 210 par rapport aux flèches dans l'état conducteur illustré à la figure 7. Les résultantes F111 et F112 ont donc des intensités supérieures à celles générées dans l'état conducteur illustré à la figure 7.In the conductive state illustrated in figure 8 the contact assembly 1 also ensures the electrical conduction between the electrical lines 10 and 20. The frank contact between the terminal members 100 and 200 is also ensured in the conducting state of the figure 8 . In this conductive state, the thrust forces of the end members 100 and 200 towards each other are greater than those exerted in the conductive state illustrated in FIG. figure 7 . These higher thrusts induce larger arrows at the respective distal portions 114 and 214 of the end portions 110 and 210 relative to the arrows in the conductive state illustrated in FIG. figure 7 . The resultants F111 and F112 therefore have intensities greater than those generated in the conductive state illustrated in FIG. figure 7 .

Un organe terminal conforme à l'invention permet d'exercer des efforts de cohésion mécanique notamment suivant la direction longitudinale, donc de garantir un contact électrique franc.
