Abstract

An electrical socket and pin connector. More particularly, the socket and pin are made from conductive material by stamping and forming. The socket includes a cylindrical mating portion defined by cantilever beams having one or more blades and wherein some blades include a rearwardly extending free end. The pin includes a mating portion having a bullet nose at one end and a wire barrel at another end.

Claims

1. An electrical pin and socket connector for electrically interconnecting a pair of wires, comprising:

a socket made by stamping and forming and having a cylindrical receptacle portion at one end, a connecting section extending rearwardly therefrom and a wire barrel attached to and extending from said connecting section, said receptacle portion being defined by a plurality of axially extending resilient, cantilever beams having inwardly facing convex surfaces adjacent a pin receiving opening to the receptacle portion; and

a pin made by stamping and forming and having a cylindrical mating portion at one end and a wire barrel at another end, said mating portion having a bullet nose, insertion limiting ears extending outwardly from opposite sides thereof for cooperative engagement with said cylindrical receptacle portion and an outer diameter slightly greater than the inner diameter of the convex surfaces of the receptacle portion, said mating portion being slidably received in the receptacle portion to electrically interconnect wires which may be terminated in the respective wire barrels, said wire barrel of said pin having wire stopping ears extending interiorly from opposite sides thereof.

2. The connector of claim 1 wherein the wire stopping ears and insertion limiting ears on each of the opposite sides of said pin are defined by common orthogonal slits.

3. The connector of claim 1 wherein each of said beams include at least two blades defined by a slot therebetween and with one of said blades being attached to the connecting section and with the other blade being free therefrom.

4. The connector of claim 3 wherein said blades join together towards the pin-receiving opening.

5. The connector of claim 1 wherein the wire barrel on the socket extends normally outwardly.

6. The connector of claim 5 further including wire stop means extending inwardly from the connecting section of the socket and projecting axially towards the wire barrel.
