Abstract
Abstract A coaxial connector is provided which can be used in cable systems which transmit telephone and internet service in addition to traditional cable television service. The coaxial connector comprises a housing which can consist of one or several components having a central bore therethrough and a one or multiple piece insulator arranged in the central bore in the housing. The coaxial connector also includes a female center contact member which is arranged in the hollow interior of the insulator. The female contact member comprises an outer surface which defines an open mating end which is adapted to receive the center conductor pin of a mating male connector and includes a pair of double bellows spring portions which extend inwardly from the outer surface. A pair of raised bumps are arranged on the contact surface of each double bellows spring portion in order to focus the contact force provided by the double bellows spring portions.
