Abstract:
A connector socket including:an insulator body integrally having a main body portion and a front portion extending forwardly from a front end of said main body portion, said front portion including a planar plate-like contact support and first key boss both extending forwardly from the front end of said main body portion; a metallic cover surrounding the insulator body, said metallic cover having a forward portion forming at least a part of cylinder which defines a part of annular groove between said front portion of said insulator body and said cylinder for receiving therein a tubular metallic cover of a corresponding connector plug; a plurality of contacts each formed of a narrow flat strip metal extending in an axial direction of said metallic cover and being arranged in juxtaposition with each other and supported on both of the opposite plate surfaces of the contact support at least one of said plurality of contacts having a forward end retracted rearwardly from that of the other contact or contacts and said planar plate-like contact support having protrusions in front of the forward ends of the contacts; and said first key boss having a side surface opposing the plate surface of the contact support in parallel thereto, a semi-cylindrical surface defining a part of inner periphery of said annular groove and at least one lateral surface which is perpendicular to the plate surface of the contact support, a position of the lateral surface along a width of the contact support uniquely defining a type of connector to distinguish from different types of connector sockets.
