6 Claims. (Cl. 339-184) This invention relates to electrical connectors, and more particularly to connectors employing a plurality of engaging contacts, so that the connector may join a multiplicity of independent electrical circuits.
It is an object of this invention to provide a simplified connector in which the individual contacts thereof can not be rnismated.
It is another object of this invention to provide means to insure proper registry of opposed contacts in a. multicircuit connector.
It is another object of this invention to provide improved and simplified means for polarizing engaging connector members so that they can not be mismated.
It is a further object of this invention to provide a connector member of simplified yet sturdy design, which is quickly assembled with a minimum of bonding points and which is rugged in character.
It is another object of this invention to provide a connector in which the individual extended contacts are sheltered or protected.
It is a still further object of this invention to effect polarizing of a connector by the inherent shape of the connector members and without derogating from the contact-containing capacity of the connector.
In accordance with these and other objects which will become apparent hereinafter, a preferred embodiment of the instant invention will now be described in connection with the accompanying drawing wherein:
Fig. 1 is a perspective view of the connector showing the male and female members joined. N
Fig. '2 is a perspective view showing the members of the connector separated.
Fig. 3 is a longitudinal section taken on line 3-3 of Fig. 1.
Fig. 4 is a cross-section taken on line 44 of Fig. 1.
Fig. 5 is a fragmentary section taken on line 5-5 in Fig. 3.
Fig. 6 is a perspective view of-the individual mating contacts. 1
Referring to the drawings, Fig.1 shows an electrical connector comprising a male member 11 joined to ;a
female member 12. Each connector member embodies a plurality of individual contacts. In the embodiment shown,-the male member 11 carries aplurality of substantially identical elongate socket contacts or sockets arear portion 17 having an open rear face. The portions 16 and 17 have contiguous transverse flanges 18 and 19, respectively, whichare-secured together means of eyelets 21- to'unify the-male'membenfl. The male member also includes, within ;the near shell 16-17,
non conductin'g body meansinwhich are mounted the {socket contacts '13. "The bo'dy means "consists: ofaforivard body port-ion 22'and a--rear body--portioir 23 con- "ice tiguously disposed behind the body portion 22. The forward or front face 24 of the forward body portion 22 is substantially flush with the forward edge of the forward shell portion 16, which is substantially in the form or outline of a keystone or symmetrical trapezoid, as best seen in Fig. 2. Around the rear edge of the body portion 22 extends an integral flange 2 6 the forward face of which engages the flange 18 to limit forward disposition of the body portion 22 within the male shell.
The body portion 22 is provided with a plurality of bores 27 through which pass the elongate socket contacts 13. The bores 27 are countersunk from. the rear face of the body 22, the several countersinks 28 being circular, as shown in Fig. 5, except for opposed inwardly extending body segments 29 which form flats 31 on the countersinks. Each socket contact 13 is provided with a shoulder 32, which mates within the countersink 28 and has flats 33 corresponding to the countersink fiats 31. In this manner the sockets 13 are restrained against rotation in their bores 27.
The forward face 34 of the shoulder 32 engages the floor of the countersink 28 to limit forward disposition of the socket 1 3 in the male member. To limit rearward disposition of the socket 13 and thereby restrain the socket within the male member, there is provided the above mentioned rear body portion 23'," which hasa plurality of bores just large enough to accommodate passage of the rearward portion of the sockets 13. Thus, engagement of the rear face of the shoulder 32 with the body portion 23 immediately circumjacent its bores serves to hold the sockets 13 within the male member 11, without relying in any way on undependable trio-- tional engagement of the contacts in the body.
The rear body portion 23 is in turn held in place by an inwardly extending rear flange 36 on the rear shell 17, which engages the edge of the body portion 23' torestrain it against rearward motion.
The female member 12 is constructed generally similar to the male member 11. In the member 12', however, the elongate contacts 1 1 are in the form of pins; and instead of terminating flush with the forward or front face 37 of the' forward body portion 38, the pins 14 extend beyond the front face 37 so as to be engageable in the bores 39 of the recessed socket contacts The forward shell portion of the female member 12 comprises a wall 41 which surrounds the forwardly eittended ends of the pins 14, and is also in the form or outline of a keystone or symmetrical trapezoid, so that it may mate snugly around the keystone-shaped forward shell 16 of the male member 11.
The'wall 41 thus serves the double function ofpolar- .izing the connector, and also protecting the extended pins 14. The keystone shape of the mating shells effects polarization of the connector, without derogating from the contact capacity of the connector, so that a maxi-- mum number of mating pins and sockets-maybe included in the connector. Where special polarizing keyways are employed, not only are stamping problems multiplied, but there is often a reductionin thecapacity of the connector to accommodate contacts. This-is of great importance in the field of miniature and: sub-miniature connectors, where it is necessary to :link a maximum number ,of, circuits in ,a ,minimum space.
the flats of the bore coun ersink.
Likeits counterpart rear body-portion 23, the rear body portion 44 of the female member 12 has a plurality of bores through which pass the rear portions of the pins 14. The female member 12 is completed by the open faced rear shell 46 having a rear flange 47 engaging the edge of the body portion 44 to complete assembly of the female member 12. The shells 4i and do are secured together by eyelets 48 passing through the contiguous flanges of the respective shells.
While the instant invention has been shown and de scribed herein in what is conceived to be the most pracdeal and preferred embodiment, it is recognized that partures may be made therefrom within the scope of the invention, which is therefore not to be limited to the details disclosed herein but is to be accorded the full scope of the claims.
