Connector having wire-in-slot connecting means and crimped strain relief

Claim 1

A preloaded multi-contact electrical connector of the type comprising an insulating housing having a mating face, a wire entry face, oppositely directed endwalls, and oppositely directed sides extending between said faces, a plurality of side-by-side cavities extending through said housing and between said faces, each of said cavities having opposed cavity sidewalls which extend normally of said sides of said housing and having a floor, each of said cavities having a wire-admitting portion which opens onto one of said sides and which extends from said wire entry face at least partially towards said mating face, an electrical contact terminal in each of said cavities, each of said terminals having a contact portion which is proximate to said mating face and a wire-rereceiving portion which is intermediate said faces and adjacent to said wire-admitting portion of its respective cavity, said wire-receiving portion having a free end which is adjacent to said one side of said housing and having wire-receiving slot means extending inwardly from said free end, said slot means having inner end portions dimensioned to penetrate the insulation of said wire and establish electrical contact with the conducting core thereof upon movement of said wire laterally of its axis and into said slot means, said connector being characterized in that: each of said terminals, has a crimpable strain relief portion integral therewith proximate to said wire entry face, said strain relief portion having a web and terminal sidewall means extending from said web towards said one side of said housing, said terminal sidewall means having tool engageable free end portions which are spaced from said cavity sidewalls of the cavity in which said terminal is disposed thereby to permit engagement with a crimping tool and bending of said terminal sidewall means towards said web, said cavity sidewalls having notches therein, said free end portions of said terminal sidewall means being received in said notches whereby, upon placement of a plurality of wires in side-by-side relationship and in alignment with said terminals, and upon movement of said wires of their axes and into said wire-receiving portions of said terminals, said wires will be located on said webs, and upon bending of said sidewall means towards said webs and against said wires, said crimpable portions will be crimped onto said wires and said wires will extend from said wire entry face of said housing.
