Claim 1
Independent Claim
413 words
An electrical connector receptacle comprising a dielectric housing having top, bottom, side, and rear walls defining a generally rectangular longitudinally extending forwardly opening plug receiving cavity, said bottom and rear walls cooperating to define a plurality of contact receiving channels communicating with said plug receiving cavity, each of said channels having an upwardly facing lower surface including a main portion and a ramp portion forming a first junction with said main portion and inclined forwardly and downwardly from said first junction and away from said main portion, a pair of opposing side surfaces and a forwardly facing rear surface forming a second junction with said lower surface, said rear wall further defining an upper surface of each of said channels, a plurality of unitary resilient spring contact members supported in generally parallel side-by-side relation to each other within said housing, each of said contact members being disposed within an associated one of said channels between said side surface thereof, each of said contact members having a front end portion supported on said main portion proximate said first junction and inclined upwardly and rearwardly from said main portion, an arcuately upwardly bowed contact portion integrally connected at its forward end to the rear end of said front end portion for engaging an associated plug contact on a plug having a body supporting the plug contact and received within said cavity, a rear transitional portion integrally connected at its forward end to the rear end of said contact portion and extending downwardly and rearward therefrom, said transitional portion including an upwardly reversely bent rear end portion supported at said second junction by said lower surface and said forwardly facing rear surface, and a rear terminal portion integrally connected at its rear end to a forward end of said reversely bent rear end portion and extending generally forwardly and upwardly away from said second junction and terminating at a free end, said free end exerting biasing force upon said upper surface, and a plurality of connector receiving apertures extending through said rear wall, each of said apertures communicating with an associated one of said channels said front end portion of each contact member engaged with an associated contact on a plug received within said housing being supported by said main portion, said front end portion of each contact member engaged with an associated portion of the body of a plug received within said cavity being generally supported by said ramp portion forward of said first junction.
