Abstract
A method of making an electrical contact wherein the contact includes a plurality of axially aligned wires (200) extending from a forward end (110) of a holder which has a rear portion (130) for receiving an electrical conductor (300). The holder (100) is manufactured by stamping it as a flat metallic piece with enlarged forward and rear portions then forming the forward portion (110) in a die to form a socket like portion for the plurality of fine, axially aligned wires and forming the rear portion (130) to receive the conductor (300).
Claims8
A method of making a hermophroditic electrical contact comprising the steps of:
- stamping a contact body as a single flat piece of electrically conducting stock having uniform thickness and including forward and rear portions, said stamping of the forward portion including stamping the forward portion into a generally rectangular portion having interfitting side edges;
- forming the forward portion of the contact body into a generally cylindrically-shaped socket by progressively bending the edges around to a position where the interfitting edges form a seam;
- inserting a plurality of fine parallel contact wires into the forward socket of the contact body;
- and
- crimping the foward portion of the contact body at a first location near the rear end thereof to retain the wires therein and at a second location longitudinally forward of the first location, said crimping at a plurality of spaced locations for axially aligning said contact wires with each other and the socket.

A method of making an electrical contact comprising the steps of:
- stamping a contact body as a single flat piece of electrically conducting stock having uniform thickness and including forward and rear portions, said stamping of the forward portion including stamping the forward portion into a generally rectangular portion having a lateral offset along one side and a complementary lateral projection along the other side;
- forming the forward portion of the contact body into a generally cylindrically-shaped socket by progressively bending the edges around to a position where the edges adjoin at a first seam with the lateral projection interfitting within the lateral offset at a seam portion which is circumferentially offset from the first seam;
- inserting a plurality of fine contact parallel wires into the forward socket of the contact body;
- and
- crimping the forward portion of the socket of the contact body at a first location near the rear end thereof to retain the wires therein.

- and
- crimping the forward portion of the socket of the contact body at a first location near the rear end thereof to retain the wires therein and at a second location longitudinally forward of the first location, said crimping at two longitudinally spaced locations for axially aligning said contact wires with each other and the socket.

A method of making a mateable hermaphroditic electrical contact comprising the steps of:
- stamping a contact body from a flat piece of electrically conducting stock, said stamping providing the flat piece with a generally rectangular forward portion having oppositely disposed first and second sides, each of said sides having therealong a laterally offset portion;
- forming the rectangular forward portion of the flat piece into a contact body having a generally cylindrically-shaped socket by progressively bending the sides around to a position where the sides adjoin at a seam and the laterally offset portions interfit;
- arranging several pieces of conductive wire in parallel relationship;
- inserting one end of the wires into the socket exposing the other end of the wires for mating;
- and
- crimping at least a portion of the cylindrically-shaped socket to retain the wires therein, whereby the retained and aligned wires and the cylindrically-shaped socket provide the mateable hermaphroditic electrical contact.
