Title: ELECTRICAL CONNECTOR
Abstract:
An electrical connector (10) comprises a socket (11) with an annular recess (12), which has an electrically conductive outer annular wall surface (13a) and an electrically conductive inner annular wall surface (13b) electrically isolated therefrom, and a plug (18) with an annular projection (21), which is receivable in the recess (13) of the socket to be spaced from the outer and the inner annular wall surfaces (13a, 13b) of the recess and which has an electrically conductive outer annular wall surface (21a) and an electrically conductive inner annular wall surface (21b) electrically isolated therefrom to establish separate electrical paths when the projection (21) is fully received in the recess (13). The connector further comprises a first resilient electrically conductive annular contact element (25) retained in a groove (26) in the outer annular wall surface (13a) of the recess and resiliently compressible to produce an electrical connection of the opposing surfaces (13a, 21a) of the recess and projection and a second resilient electrically conductive annular contact element (27) retained in a groove (28) in the inner annular wall surface (13b) of the recess and resiliently compressible to produce an electrical connection of the opposing surfaces (13b, 21b) of the recess and projection.
