Claims
- 1. A method of making electrical connector receptacles of the type comprising an insulating housing havng a plug-receiving end and a rearward end, a plug-receiving opening extending into said plug-receiving end, said opening having opposed internal sidewalls and opposed internal endwalls, said housing having oppositely directed external sidewalls and oppositely directed external endwalls, a plurality of electrical conductors with each of said conductors having an intermediate portion in side-by-side spaced-apart relationship, each of said conductors comprising a first end which serves as a contact spring extending from one of said internal sidewalls diagonally into said opening and towards said rearward end, an intermediate portion extending from said plug-receiving end through said housing between said one internal sidewall and the adjacent external sidewall and towards said rearward end, and a second end which extends externally of said housing, said plug-receiving opening being dimensioned to receive a connector plug having spaced-apart contact members therein which engage said contact springs, said method comprising the steps of:
- stamping a continuous strip of conductive sheet metal to produce a continuous strip comprising a carrier strip having groups of blanks for said conductors extending therefrom at spaced intervals with the number of conductor blanks in each group being equal to the number of conductors in said connector receptacle,
- feeding said strip through a forming die and forming said conductor blanks to the shape of said conductors in said connector receptacle,
- intermittently feeding said strip to a molding apparatus having a mold cavity which conforms to the shape of said housing and having core pins in said mold cavity which conform to the shape of said plug-receiving opening, positioning one of said groups of formed conductors in said cavity with said contact portions of said conductors held between said core pins,
- injecting molding material into said cavity, opening said mold, and feeding said strip whereby,
- said strip, when it emerges from said mold, has connector housings molded on each of said groups of conductors with molding material surrounding said intermediate portions of said conductors.
- 2. The method set forth in claim 1 including the step of severing said conductors from said carrier strip after said strip is fed from said mold.
- 3. The method set forth in claim 1, said connector receptacles each having two metallic mounting posts extending from said housing with said second ends of said conductors being between said mounting posts, said method including the steps of forming two mounting post blanks for each of said groups of conductors during stamping of said strip with said conductor blanks of each group between said mounting post blanks.
- 4. A method of making electrical connector receptacles of the type comprising an insulating housing having a plug-receiving end and a rearward end, a plug-receiving opening extending into said plug-receiving end, said opening having opposed internal sidewalls and opposed internal endwalls, said housing having oppositely directed external sidewalls and oppositely directed external endwalls, a plurality of electrical conductors having intermediate portions in side-by-side spaced-apart relationship, each of said conductors comprising a first end which serves as a contact spring extending from one of said internal sidewalls diagonally into said opening and towards said rearward end, an intermediate portion extending from said plug-receiving end through said housing between said one internal sidewall and the adjacent external sidewall and towards said rearward end, and a second end which extends externally of said housing, said plug-receiving opening being dimensioned to receive a connector plug having spaced-apart contact members therein which engage said contact springs, said method comprising the steps of:
- stamping a continuous strip of conductive sheet metal to produce a continuous strip comprising a carrier strip having groups of blanks for said conductors extending therefrom at spaced intervals with the number of conductor blanks in each group being equal to the number of conductors in said connector receptacle,
- feeding said strip through a forming die and forming said conductor blanks to the shape of said conductors in said connector receptacle,
- intermittently feeding said strip to a molding apparatus comprising two mold parts which are movable against each other to form a mold cavity, each mold part having a core pin extending into the mold cavity, positioning one of said groups of conductors between said mold parts and clamping said first ends of said conductors between said core pins and clamping said carrier strip and said second ends of said conductors between said mold parts,
- injecting molding material into said cavity and thereby surrounding said intermediate portions of said each group of blanks, moving said mold parts away from each other, and feeding said strip to feed a molded housing on said strip from said molding apparatus.
