US Patent 7182648 Optical-electric connector with improved contact having coil spring

An optical-electric connector (1) has an insulative housing (10), a plurality of contacts (21, 22, 23, 24, 25) received in the housing, and an optical-electric converter (30) assembled in the housing. The housing defines a receiving space (14) for receiving a mating plug and a plurality of passageways (16) for receiving the contacts. One of the resilient contacts forms an elastic contacting arm (212) extending into the receiving space and a retention section (211). A coil spring (214) is assembled between the retention section and the elastic contacting arm. The retention section of the contact securely holds the coil spring in its place.
