Schjeldahl Company, Northfield, Minn., a corporation of Minnesota Filed Dec. 5, 1966, Ser. No. 599,228 Claims. (Cl. 339-176) ABSTRACT OF THE DISCLOSURE This invention relates to an electrical connector for printed circuit cards. It consists of a receptacle having an elongated slot therein bordered by a series of channels having inner and outer walls and containing beryllium copper contacts. The contacts lay fiush against the outer walls of the channels and fold over so as to locate free ends within the slot.
The present invention relates generally to an electrical connector device, and more particularly to a receptacle connector assembly which is particularly adapted to receive printed circuit cards of various widths and thicknesses. The receptacle connector assembly design of the present invention provides an exceptionally thin receptacle apparatus which is adapted to receive cards of a variety of thicknesses, including cards with relatively great or wide tolerance levels, and with contact being established with a relatively firm and uniform contact pressure.
In the design of receptacle connector assemblies, particularly receptacles for printed wiring or printed circuit cards, it is frequently desirable to obtain a design which will accept cards with substantially wide dimensional tolerances. In order to accept a range of card dimensions, the design must be such as to make and establish electrical contact consistently with this variety of card designs. Furthermore, consistent with the trend toward miniaturization, a receptacle connector assembly should normally have dimensions which are as small as is reasonably possible, consistent with the strength and electrical requirements of the assembly. In the past, card receptacles of various sorts have been designed which may include certain of these desirable features, however the receptacle design of the present invention combines each of these desirable features in a straight-forward design arrangement.
In accordance with the design of the receptacle connector assembly of the present invention, a structure is utilized wherein a receptacle chamber is available having a card receiving cavity therein, the cavity being provided with contact elements along oppositely disposed major side or lateral surfaces thereof. These contact elements are arranged along channels which are formed in the side Walls of the receptacle, one channel being formed along the outer surface to receive the shank portion of the contact or contact element, the other channel being formed along the inner surface to receive the inner-connecting portion of the contact or contact elements. Between these inner and outer channels, there is arranged a generally arcuate tip area which accommodates a similarly formed arcuate coupling segment along the contact element between the shank portion of the contact and the innerconnecting portion, and this radius formation provides for a fulcrum point or flexure zone which is disposed at a substantial distance from the actual contact area, thus providing long lever arm action with maximum deflection consistent with minimum and uniform contact pressures. The arcuate tip is recessed from the top of the side wall to prevent twisting of the contact from or about its axis. In addition, this particular design provides for a wide variety of dispositions of the tail portion of the contacts such as may be required on a generally universal connector application of this type.
Therefore, it is an object of the present invention to provide an improved receptacle connector assembly which has a minimum size, and which is adapted to receive printed circuit cards having wide tolerance levels. The electrical contact to the cards is uniform and consistent, this contact being with relatively uniform and low contact pressures.
It is a further object of the present invention to provide an improved receptacle connector assembly which is adapted to receive printed circuit cards, the card insertion depth being maximum for the connector size.
It is yet a further object of the present invention to provide an improved receptacle connector assembly for receiving printed circuit cards which provides for maximum deflection of contacts along with a maximum wiping action between the contacts and the circuit board conductors.
Other and further objects of the present invention will become apparent to those skilled in the art upon a study of the following specification, appended claims, and accompanying drawings wherein:
FIGURE 1 is a top plan view of a typical receptacle connector assembly prepared in accordance with the present invention, the view showing a portion of the contact elements removed;
FIGURE 2 is a front elevational view of a connector of the type shown in FIGURE 1, with a portion of the contact being removed;
FIGURE 3 is an isometric view of a cut-away portion of the connector shown in FIGURES 1 and 2, this figure being a somewhat enlarged scale, and showing an exploded relationship therewith, a printed circuit board which is adapted for being received within the connector cavity; and
FIGURE 4 is an isometric view similar to FIGURE 3 showing a somewhat modified form of arranging the tail portions of the contact within the assembly.
In accordance with the preferred modification of the present invention, particularly as shown in FIGURES 13, the receptacle connector assembly generally designated 10 includes a body portion 11 with a pair of lateral side walls 12 and 13 along with the end walls or lugs 1414. The receptacle is adapted to receive the contact 15 within the confines of the cavity formed between the various walls. As shown in FIGURES 1 and 3, the side walls include spacer lug areas 1616 which separate the individual contact receiving channels formed therebetween. In other words, the individual contacts are disposed in channels which are formed along and within both inner and outer surfaces of the side walls between the individual lugs 1616. With regard to the contact element 15, it will be seen that each includesa tail portion 17, an outer shank portion 17a, and an inter-connecting portion 18. The individual contacts are arranged along the channels formed in the side walls and against the web portions 19 which are disposed between the lug portions 16, these web portions remaining between the inner and outer channels of the individual side walls. A bottom surface 19a, as shown in FIGURE 4, is utilized as a connecting web between the individual side or lateral walls.
A particularly important feature of the apparatus is shown in detail in FIGURE 4, wherein the web portion 19 is shown to terminate in a generally arcuate outer tip, such as at 19b. This tip is recessed below the top of the side wall. Accordingly, a portion of the contact element or member is dispose-d over the arcuate outer tip and is provided with an arcuate coupling segment between the shank portion and the contact portion such as is shown at 21 in FIGURE 4, this coupling segment having an inner radius which is substantially equal to the outer radius of the generally arcuate outer tip portion of the web 19. In other words, the radius of the tip portion 19b substantially matches the radius of the coupling segment 21 of the individual contacts. It will be appreciated that these features are common between FIGURES 3 and 4, and for purposes of clarity, these details have been shown in connection with the device illustrated in FIGURE 4.
In forming the receptacle connector assembly of the present invention, the body portion comprising the end walls 1414, together with the spacing lugs 16, and webs 19 and 19a is initially formed. Thereafter, the individual contacts are inserted in place in the area of the individual webs 19. Thereafter, the side walls are covered with insulating panels such as are shown at 12 and 13. As an alternative, the panels may be provided with inwardly extending flanges or lips to add rigidity to the structure. These individual insulating panels may be formed from a molded member consisting of a good dielectric, or may also be formed from a durable film material such as stress oriented polyethylene terephthalate or the like. These panels 12 and 13 are secured to the assembly after insertion of the individual contact therein. Mounting holes are illustrated at either end of the device, and are formed in the end Walls, as indicated.
With attention being directed to FIGURE 3 of the drawings, it is seen that the printed circuit assembly generally designated 25 and including a base member 26 and conductor areas or terminals 2727 is arranged for insertion into the receptacle assembly. As indicated, the individual terminal areas 2727 are arranged for making electrical contact with the contact portion 18 of the individual contacts 1515. If desired, the receptacle assembly may be provided with a key or other arrangement for polarizing the assembly wherever desired.
In the apparatus of FIGURES 1-3, the individual tail portions 1717 of the contacts 1515 extend downwardly from the bottom of the under surface of the bottom Wall of the assembly. In the apparatus of FIG- URE 4, these individual contacts extend outwardly from one wall portion of the assembly. It is the design of this apparatus which provides the versatility enabling the disposition of the tail portion of the contacts in essentially any desired manner. For example, the bottom wall or web portion 19a is utilized as a base for the receptacle receiving cavity, and also as an abutment surface for the lower portion of the individual contacts, such as between the tail portion 17 and the shank portion 17a. This portion of the contact also provides a retaining lug for aid in assembly. Thus, the lower connecting web of the assembly enables a Wide versatility of contact disposition together with a maximum insertion depth for the card being received within the assembly. Since the contacts are generally disposed externally of the bottom web portion 19a, it will be appreciated that this bottom web is not being utilized to support or retain these contacts in molded-in configurations, but rather is used as an abutment wall only.
It will be observed that the inter-connecting portion 18 of the contacts 15 commences at the radius or arcuate portion 21, for example, as shown in FIGURE 4. This arcuate portion provides fulcrum for deflection or flexure of the contacts and provides a maximum lever arm length between the arcuate fulcrum and the actual area of contact. This long lever arm provides a maximum deflection of the contact relative to the length thereof, and thus a wide variety of printed circuit boards having substantial tolerances may be received within the receptacle cavity.
The versatiiity of this design is accordingly broad and substantial. In addition to accepting a relatively wide range of circuit boards, the receptacle may be made in either a single or double sided configuration, the double sided configuration being shown herein. In addition, the oppositely disposed contacts can be used in connection with the plated through holes of a circuit board to provide for redundant contact features. The tail portion of the contact can be infinitely varied in their disposition, this variation being substantially within degrees, in accordance with the bottom surface of the device. In addition, as illustrated in FIGURE 4, the tail portions 22 may extend outwardly from one side of the connector assembly. If desired, the individual contacts can be staggered by suitable arrangement of the contact receiving channels in the assembly. Furthermore, since reasonably good dielectric materials may be employed along the outer panel areas, it has been found that relatively thin sheets of dielectric can be employed and permit use up through the area of 15,000 volts for a relatively thin connector device. Also a reinforcement plate may be disposed along the bottom of the connector assembly.
It will be appreciated that this receptacle connector assembly may be made of any desired length and width, it being recalled that the width is at a practical minimum for the acceptance of the various contacts employed. Furthermore, the length may be made consistent with the requirements of the printed circuit board which is to be accepted therein. Thus, modified forms of structure or contact arrangement may be employed by utilizing certain of the features of this apparatus.
It will, of course, be understood that various changes may be made in the form, details, arrangements and proportions of the parts without departing from the scope of the invention as set forth in the appended claims.
