Electrical connector

Claim 1

In an electrical contact terminal of the female socket type of mounting in a connector plug, said socket having a cylindrical elongated shape and a flared front end portion for insertion of a male contact pin, said socket being split along a major portion of its length from the front end portion to a transverse slot formed adjacent the rear end portion, a convoluted spring member integral with said socket and attached thereto at its opposite ends, said spring member having three spaced convolutions with said middle convolution projecting a greater distance into the interior of said socket than said convolution nearest said flared front end portion, the convolution furthest from said flared front end portion extending a distance into the interior of said socket approximately the same as that of the convolution nearest said flared front end portion, said convolutions being adapted for spring-like contact with an inserted male contact pin, wherein the middle convolution projecting further than the other two convolutions provides a generally centrally located force on an inserted male contact pin without tilting of the pin, each one of said convolutions forming a distinct convexly-shaped projection extending into said socket interior and located to engage said male pin.
