Plug connector

Claim 1

In a plug-socket assembly having an insulated housing with a plurality of parallel bores therethrough, the housing being formed of two parts abutting one another along a parting line substantially normal to an axis of the bores with a plurality of cylindrically-shaped conductive members received in the insulated housing, one to a bore, the conductive members forming electrical contact plug-socket members with each of the conductive members having a diameter increasing projection received in a diameter increasing bore section effective to lock the conductive members axially in the bores, the improvement being the projections comprising at least two projections spaced axially along the conductive members separated by an air gap, the air gap having a dimension between the projections at least as great as the effective length of the projections in a direction normal to the bore axis and wherein the diameter increasing portion of the bore is configured with respect to the projections to provide wall surfaces for engagement by the projections preventing both axial and rotational movement of the conductive members and wherein the at least two projections of each of the conductive members being each formed by two tabs projecting therefrom, the tabs converging towards one another at free ends of the tabs, the tabs projecting from the conductive members tangentially from a curved periphery of said conductive members at right angles relative to the axis of the bores and extending in a plane parallel to the axis of the bores, the tabs being manufactured of flat stock in a stamping-rolling technique along with the formation of the conductive member, the conductive member being formed from flat stock in a stamping-rolling technique.
