Abstract

A flat-pin receptacle comprises two contact tabs arranged on the receptacle body and resiliently in contact with each other along part of their length. A connecting spring surrounding the receptacle body presses against the outsides of each contact tab along two strip-shaped sections on the connecting spring body arranged at a distance apart. The receptacle body has recesses for receiving locking tongues which are arranged on, and can be bent away from, the receptacle housing. To facilitate assembly of the locking tongues in receptacle housings, a strip part (14) is arranged on both sides of the connecting spring (12') between the sections (13) and parallel to the latter. The strip parts (14) are bent back towards each other and inward over the free ends of the contact tabs (6) along part of their length opposite the connecting spring body (12').
