## Abstract

An electrical connector comprising an improved socket having a longitudinally extending crimped area that reduces the area of contact of a conventional pin therewith.

## Claims

### Claim 1

An electrical connector comprising
a compliant twist pin comprising a plurality of helically twisted wires connected to one another at longitudinally spaced end portions thereof, the wires at an intermediate portion of said twist pin being initially circumferentially spaced from one another and extending radially to a radius R, and
a noncompliant circumferentially closed cylindrical socket having a first plurality of circumferentially spaced longitudinally extending internal surfaces disposed at a radius greater than R and a second plurality of circumferentially spaced longitudinally extending internal surfaces between said first surfaces, respectively, and disposed at a radius less than R whereby the intermediate portions of some of said wires make initial contact with only the second plurality of internal surfaces on said socket and are radially compressed to a diameter less than R thereby to minimize the force required to assemble said pin in said socket yet provide contact pressure between said pin and socket.
