Description

Electrical connector There has long been a demand for mating connector plugs and receptacles wherein the contacts of each are arranged in a long straight row so that the connector parts may be ly attached to printed circuit boards or other types of electrical While widely the space ments of such connectors are such that difficulty has been experienced in providing smooth and positive the plugs and sockets and prior art designs have often been such that the individual contacts must be separately formed and assembled in the thus rendering the operations thereof relatively It is therefore the general aim of the present tion to avoid the known shortcomings of prior art types with a connector that is at once smooth acting and relatively More it is among the objects of the invention to provide polarizing and guide means having less tendency to cant or bind than encountered with similar connectors of comparable size and to ously provide an arrangement such that economical mounting of the contacts is achieved by molding the entire group of contacts as an integral part in a dielectric plug yet with the parts so proportioned as to fast and easy shearing of the contacts from their carrier In the FIGURE 1 is a front elevational view of a electrical connector plug as plated by the present FIGURE 2 is an end elevational view of the plug trated in FIGURE FIGURE 3 is a sectional view of the plug and one of the male contacts carried the view being taken tially on the plane of the line of FIGURE FIGURE 4 is an end plan view of the connector plug which may be considered as viewing the plug of FIGURE 1 from the bottom thereof as illustrated in the FIGURE 5 is a detail view of one of the polarizing posts of the plug with its associated FIGURE 6 is a front elevational view of a connector receptacle adapted to receive and establish electrical tact with the contacts of the plug of FIGURE the view ing taken with the portion thereof broken away to show the center channel of the receptacle with the female contacts and the side of the figure cluding a segment of the plug of FIGURE 1 with dotted line showings of the contacts and polarizing posts serving to interconnect the plug and FIGURE 7 is a detail transverse view taken on the plane of the line of FIGURE showing one exemplary type of female contact in FIGURE 8 is a fragmental end view of one side of the receptacle of FIGURE 6 which may be considered as taken on the plane of the line thereof to show one of the izing slide sockets of the and FIGURE 9 is a similar fragmental end view of the site side of the receptacle the view being considered as taken on the plane of the line to show the opposite slide The Plug The connector plug of the present illustrated in FIGURES 1 to 5 comprises a main insulating mount or body portion 10 as being relatively wide in its transverse dimension as compared to its rather thin file and while the dimensional proportions of the particular connector will vary according to the number of contacts it is usual practice to mount a tively large number of electrical contacts 12 in spaced relation so that the transverse dimension of the unit is somewhat greater than the vertical dimension as viewed in FIGURE the insulating mount 10 may be a solid dielectric member with the individual tacts 12 molded therein in the process of with each of the contacts having a reduced dimension integral lead with the end portions of the alternate leads bent outwardly to provide spaced soldering pins 16 and If apertures such as 20 or recesses 22 may be formed in the flat surface 24 of the body portion to facilitate the molding operation or to provide for sired clearances in soldering to a conventional circuit the insulating mount 10 may be provided with mounting holes 26 for attachment to a printed circuit board or other Smooth sliding coupling of the contacts 12 and parts related thereto is assured by providing the plug and tacle with paired polarizing guide posts and the pairs being of different dimensional shapes located at the opposite ends of the row of contacts the guide post 28 at the left of FIGURE 1 is of smaller cross section than the corresponding guide post 30 at the These dimensional differences in the guide posts are shown by the dimension line of FIGURE 4 the thickness of the guide post and the corresponding sion line showing the thickness of the guide post has its lower surfaces tapered to itate entrance into the coacting slide sockets of the tacle as will and each is provided with an integral web bearing against and supporting the closest adjacent tact That the guide post 28 includes the web and the guide post 30 includes the web 31 1 and The Receptacle FIGURES 6 to 9 inclusive illustrate a connector tacle adapted to receive and mate with the plug of FIGURES 1 to with the the receptacle may consist of a single unitary molded dielectric insulating body having a central channel 34 tapered at its 36 to receive the contacts of the plug and extending between the opposite end walls 38 and 40 as best seen in FIGURE The channel is dimensioned to receive the individual contact pins 12 of the plug and has integrally molded transverse slots 42 with internal shoulders 44 and 46 to interlock with bifurcated metallic spring contacts 48 between the thin front and back walls 54 of the It should be stood that the precise form of contact 48 utilized does not constitute a part of the present invention and that the nector here shown may be used in connection with many and varied contact In order to guide the plug into the receptacle in a smooth easy mating motion and prevent undue canting or ing between the parts as they are coupled or the receptacle body 32 is provided with a pair of apertures or slide sockets of a size and shape spacing corresponding to the shapes of the guide or pilot 28 and 30 of the as viewed in the receptacle has a slide socket 50 a tapered month to receive the post 28 at the other has a similar socket 52 of and area to receive guide post 30 of the slide sockets 50 and correspondingly shaped to the different dissensions of guide posts 28 and 30 to act as a polarizing in coupling of the plug It is to particularly be tha length of the ping contacts by the dimensional in substantially less than the length of the guide posts illustrated in insufficientOCRQuality
