The terminal is capable of withstanding high tightening forces.

Description

L'invention se rapporte à une borne de raccordement comportant une pièce métallique plate de faible épaisseur qui présente une surface de contact équipée d'une vis et qui est pourvue de pattes parallèles saillantes aptes à se présenter dans des ouvertures d'une carte à circuit imprimé de façon à être soudées avec une couche conductrice de ce circuit.The invention relates to a connection terminal comprising a flat metallic piece of small thickness which has a contact surface equipped with a screw and which is provided with protruding parallel tabs capable of being present in the openings of a circuit board. printed so as to be soldered with a conductive layer of this circuit.

De telles bornes, qui sont fréquemment utilisées pour transmettre des courants peu importants, sont généralement placées côte à côte à l'aide d'un support isolant pour constituer un connecteur apte à coopérer par exemple avec une multiplicité de conducteurs, les vis étant généralement disposées de façon que leurs axes soient sensiblement perpendiculaires ou légèrement inclinés par rapport au plan de la carte ; afin de donner aux extrémités des conducteurs un serrage satisfaisant, les vis sont généralement associées à une pièce métallique massive qui présente une ouverture commune où seront appliquées les unes contre les autres les extrémités des conducteurs et les surfaces de contact respectives.Such terminals, which are frequently used to transmit small currents, are generally placed side by side using an insulating support to form a connector able to cooperate, for example with a multiplicity of conductors, the screws being generally arranged. so that their axes are substantially perpendicular or slightly inclined relative to the plane of the card; in order to give the ends of the conductors a satisfactory tightening, the screws are generally associated with a solid metal part which has a common opening where the ends of the conductors and the respective contact surfaces will be applied against each other.

D'autres dispositifs connecteurs à bornes multiples pour circuits imprimés, dans lesquels les courants à transmettre sont plus importants, utilisent une multiplicité de pièces plates présentant chacune deux pattes parallèles aptes à être soudées avec une couche conductrice placée du côté opposé au connecteur, et comportant chacune une surface de contact portée par une languette apte à coopérer avec un clip ou une douille élastiques fixés par sertissage sur une extrémité de conducteur, un dispositif de maintien isolant étant associé à ces pièces plates.Other multiple terminal connector devices for printed circuits, in which the currents to be transmitted are greater, use a multiplicity of flat parts each having two parallel tabs suitable for being soldered with a conductive layer placed on the side opposite to the connector, and comprising each a contact surface carried by a tongue capable of cooperating with an elastic clip or socket fixed by crimping on one end of the conductor, an insulating holding device being associated with these flat parts.

Ces modes de réalisation de bornes de raccordement connues, présentent l'inconvénient d'être, soit uniquement destinées à la transmission de courants faibles, soit d'être fragiles en l'absence de moyens de maintien complémentaires ou lorsque le nombre de pièces plates est faible, et de faire appel à des organes de raccordement amovibles coûteux.These embodiments of known connection terminals have the drawback of being either only intended for the transmission of low currents, or of being fragile in the absence of additional holding means or when the number of flat parts is low, and to use expensive removable connecting members.

L'invention se propose de fournir une borne de raccordement dont la constitution générale réponde à celle qui est mentionnée ci-dessus et qui soit apte à transmettre des courants élevés, tout en présentant une solidité propre importante et un coût de mise en oeuvre réduit, sans faire appel à des moyens de maintien supplémentaires.The invention proposes to provide a connection terminal whose general constitution corresponds to that which is mentioned above and which is capable of transmitting high currents, while having a significant inherent solidity and a reduced cost of implementation, without using additional holding means.

Selon l'invention, le résultat visé est atteint grâce au fait que la pièce métallique présente deux ailes, pliées autour d'une arête commune perpendiculaire à la carte, de façon à faire entre elles un angle déterminé, et comporte trois pattes dont l'une est voisine de l'arête, tandis que les deux autres sont éloignées de celle-ci, un trou fileté apte à coopérer avec une vis de borne étant disposé dans l'une des ailes de façon telle que son axe soit sensiblement parallèle au plan de la carte, les pattes parallèles étant engagées dans des ouvertures métallisées de la carte et soudées avec celles-ci.According to the invention, the desired result is achieved thanks to the fact that the metal part has two wings, folded around a common edge perpendicular to the card, so as to make between them a determined angle, and has three legs, the one is close to the edge, while the other two are remote from the latter, a threaded hole capable of cooperating with a terminal screw being disposed in one of the wings so that its axis is substantially parallel to the plane of the card, the parallel tabs being engaged in metallized openings of the card and welded therewith.

L'invention sera mieux comprise à la lecture de la description ci-après.The invention will be better understood on reading the description below.

Une carte à circuit imprimé 1, visible à la figure 2 et comportant une plaque isolante 2 et une couche conductrice 3, reçoit une borne 4 qui est placée du côté où se trouve cette couche conductrice.A printed circuit board 1, visible in FIG. 2 and comprising an insulating plate 2 and a conductive layer 3, receives a terminal 4 which is placed on the side where this conductive layer is located.

Cette borne comporte principalement une pièce métallique 5 qui est visible, en particulier, à la figure la et qui est obtenue par pliage, autour d'une arête 7, d'une pièce plate découpée 5"' , de façon à former deux ailes 5' et 5" faisant entre elles un angle α déterminé, voir aussi les figures lb et 2.This terminal mainly comprises a metal part 5 which is visible, in particular, in FIG. 1 a and which is obtained by folding, around an edge 7, a flat cut part 5 "', so as to form two wings 5 'and 5 "forming between them a determined angle α, see also Figures 1b and 2.

Cette pièce 5 présente sur l'aile 5' une surface de contact ou de raccordement 5 qui est pourvue d'une ouverture filetée 8 d'axe XX' perpendiculaire à celle-ci.
D'un côté 9 de l'aile 5', qui est opposé à l'aile 5", est engagé dans le trou 8 un organe de serrage 10 comprenant une vis 11, ayant une tête 12 et un étrier percé 13 qui est placé sous cette tête.This part 5 has on the wing 5 'a contact or connection surface 5 which is provided with a threaded opening 8 of axis XX' perpendicular thereto.
On one side 9 of the wing 5 ', which is opposite the wing 5 ", is engaged in the hole 8 a clamping member 10 comprising a screw 11, having a head 12 and a pierced stirrup 13 which is placed under this head.

Au voisinage des deux extrémités opposées 14, 15 des deux ailes et respectivement de l'arête 7, la pièce 5 possède trois pattes parallèles 16, 17, respectivement 18, qui sont placées dans les plans où circulent les deux ailes respectives.In the vicinity of the two opposite ends 14, 15 of the two wings and respectively of the edge 7, the part 5 has three parallel legs 16, 17, respectively 18, which are placed in the planes where the two respective wings circulate.

Deux bords alignés 19 et 20 de la pièce 5 sont situés entre les pattes 17, 18, respectivement 18, 16,-avant que la pièce découpée 5' ' ' ne soit pliée et sont placés dans un même plan RR', visible à la figure 3, lorsque la pièce 5 a été pliée, l'arête 7 étant sensiblement perpendiculaire à ce plan.Two aligned edges 19 and 20 of the piece 5 are located between the tabs 17, 18, respectively 18, 16, -before the cut piece 5 '' 'is folded and are placed in the same plane RR', visible on the Figure 3, when the part 5 has been folded, the edge 7 being substantially perpendicular to this plane.

La couche conductrice 3 et la plaque isolante 2 sont percées de trois ouvertures 22, 23, 24 métallisées intérieurement dont les écartements correspondent à ceux des pattes 17, 18 et 16 de sorte que la pièce 5 peut être associée à la carte à circuit imprimé 1 en faisant pénétrer ces pattes dans ces ouvertures, voir figure 3, jusqu'au moment où les bords 19, 20 viennent à proximité immédiate de la couche 3.The conductive layer 3 and the insulating plate 2 are pierced with three internally metallized openings 22, 23, 24 whose spacings correspond to those of the tabs 17, 18 and 16 so that the part 5 can be associated with the printed circuit board 1 by making these tabs penetrate into these openings, see FIG. 3, until the edges 19, 20 come in close proximity to the layer 3.

Afin de réaliser la fixation de la pièce 5, un cordon de soudure 21 est déposé sur la couche conductrice de manière à mouiller simultanément, d'une part les bords 19 et 20 et, d'autre part, les pattes 19, 17, 16 et les trous métallisés correspondants.In order to fix the part 5, a weld bead 21 is deposited on the conductive layer so as to wet simultaneously, on the one hand the edges 19 and 20 and, on the other hand, the tabs 19, 17, 16 and the corresponding metallized holes.

Lorsque la pièce 5 est fixée, l'axe XX' de la vis 10 est sensiblement parallèle au plan PP' de la carte 1, et se trouve séparé de la face voisine 27 de celle-ci par une distance "d" telle qu'un bord 25 de l'étrier de forme rectangulaire 13 soit guidé sans tourner lors du serrage de la vis ; l'orientation d'un étrier de forme cambrée, représenté à la figure 2, peut être faite de manière que des extrémités de conducteurs soient introduites entre lui et la surface de contact 6, soit parallèlement, soit perpendiculairement au plan de la carte 1.When the part 5 is fixed, the axis XX ′ of the screw 10 is substantially parallel to the plane PP ′ of the card 1, and is separated from the neighboring face 27 thereof by a distance "d" such that an edge 25 of the rectangular stirrup 13 is guided without turning when tightening the screw; the orientation of a cambered stirrup, shown in Figure 2, can be done so that ends of conductors are introduced between it and the contact surface 6, either parallel or perpendicular to the plane of the card 1.

Une portion annulaire 26, repoussée concentriquement au trou 8 lors du découpage de la pièce 5''', permet d'offrir à la vis un nombre de filets suffisant malgré l'épaisseur réduite de cette pièce.An annular portion 26, pushed concentrically with the hole 8 during the cutting of the part 5 '' ', makes it possible to offer the screw a sufficient number of threads despite the reduced thickness of this part.

L'angle a et les longueurs des ailes seront choisies pour que les efforts exercés axialement et angulairement sur la borne par un tournevis soient largement inférieurs aux couples de fixation résistants opposés par celle-ci et pour que l'extrémité de la vis ne vienne pas s'appuyer sur l'aile 5". Des angles compris entre 45° et 135° ont donné toute satisfaction.The angle a and the lengths of the wings will be chosen so that the forces exerted axially and angularly on the terminal by a screwdriver are much less than the resistant fixing torques opposed by the latter and so that the end of the screw does not come lean on the 5 "wing. Angles between 45 ° and 135 ° were satisfactory.

Grâce à la stabilité et à la rigidité d'association données à cette borne par la soudure des trois pattes dans leurs ouvertures et la soudure des bords contre la couche conductrice, le couple de serrage important, qu'il est nécessaire de communiquer à la vis pour assurer un raccordement électrique apte à transmettre des courants importants, ne provoque ni déformation dangereuse de la carte, ni décollage de la couche conductrice. Une fixation encore meilleure est obtenue lorsque des cordons de soudure, tels que 28', 28", relient les extrémités 16', 17', 18' des pattes 16, 17, 18 à une seconde couche conductrice 30 déposée sur la face 29 opposée à la face 27.Thanks to the stability and the rigidity of association given to this terminal by the welding of the three tabs in their openings and the welding of the edges against the conductive layer, the significant tightening torque, which it is necessary to communicate to the screw to ensure an electrical connection capable of transmitting large currents, does not cause dangerous deformation of the card, nor take-off of the conductive layer. Even better fixing is obtained when weld beads, such as 28 ', 28 ", connect the ends 16', 17 ', 18' of the tabs 16, 17, 18 to a second conductive layer 30 deposited on the opposite face 29 on face 27.

Lorsqu'une carte à circuit imprimé comporte une ou plusieurs bornes conformes à la description qui vient d'en être faite et que cette carte est disposée dans un boîtier, il n'est pas nécessaire de réaliser (comme cela était nécessaire avec l'art antérieur afin d'éviter des contraintes mécaniques sur la carte), une correspondance très rigoureuse entre les logements de bornes prévus dans le boîtier et les bornes elles-mêmes la localisation des différentes bornes sur la carte requiert donc moins de précision, ce qui diminue le coût technique des appareils qui les utilisent.When a printed circuit board has one or more terminals conforming to the description which has just been made and this card is disposed in a housing, it is not necessary to carry out (as was necessary with art in order to avoid mechanical constraints on the card), a very rigorous correspondence between the terminal housings provided in the housing and the terminals themselves the location of the different terminals on the card therefore requires less precision, which reduces the technical cost of the devices that use them.

Dans une disposition avantageuse, qui est visible à la figure 4, un appareil 31 comporte un boîtier isolant de faible épaisseur 32 qui présente un fond 37 et un volume central 33 entouré par des parois périphériques telles que 34, 35, 36.In an advantageous arrangement, which is visible in FIG. 4, an apparatus 31 comprises a thin insulating box 32 which has a bottom 37 and a central volume 33 surrounded by peripheral walls such as 34, 35, 36.

Les parois telles que 35 possèdent une série de logements de bornes, tels que 38, 39, 40 ..., qui sont aptes à recevoir, avec un jeu relativement important, des bornes telles que 41, fixées à la périphérie 48 d'une carte à circuit imprimé 44 et d'axes parallèles XX', X", X"'. Chaque logement, tel que 39, présente une cavité de borne 45, une ouverture d'accès 46 pour un tournevis et une entrée 47 perpendiculaire pour une extrémité de conducteur à raccorder. Cette ouverture, cette cavité et cette entrée débouchent sur une face 42 du boîtier opposée au fond 37 qui intéresse une région particulière 49 du boîtier (voir figure 5).The walls such as 35 have a series of terminal housings, such as 38, 39, 40, etc., which are capable of receiving, with a relatively large clearance, terminals such as 41, fixed to the periphery 48 of a printed circuit board 44 and with parallel axes XX ', X ", X"'. Each housing, such as 39, has a terminal cavity 45, an access opening 46 for a screwdriver and a perpendicular inlet 47 for one end of the conductor to be connected. This opening, this cavity and this entry lead to a face 42 of the housing opposite the bottom 37 which concerns a particular region 49 of the housing (see FIG. 5).

Un couvercle isolant plat 43 ferme le volume 33 et maintient la carte à laquelle il est parallèle ; la coopération des parois des logements et des vis de bornes est avantageusement prévue pour rendre celles-ci imperdables.A flat insulating cover 43 closes the volume 33 and holds the card to which it is parallel; the cooperation of the housing walls and the terminal screws is advantageously provided to make them captive.
