Abstract: An electrical connector with a first housing part receiving socket contacts, and a second housing part receiving knife contacts, where the two parts of the housing can be locked together and released by means of pins or the like, firmly attached to the housing parts. A single U-shaped clamp is mounted on one part of the housing and has legs with linking grooves in the region of board-shaped expansions. The grooves can be swung onto pins of the other housing part. The legs are provided with springy chamfers which, in the release position, are braced as stop elements again that housing part which carries the clamp. A locking hook mounted resiliently on a housing part reaches releaseably into a recess or hole in the cross piece of the clamp when the latter is in the locking position.

Abstract: Electrical coupling device with a measuring contact bank fixedly mounted on an appliance frame and a bush contact bank arranged inside a housing, where one of the front ends of the housing can be fixed on the appliance frame while its other front end can be fastened by means of a hook provided on the housing and a corresponding nose on the apparatus frame. In said electrical device, the housing (5) is provided with a frame (9) and modular bush contacts (11) are arranged in the inner part (9') of the housing.

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 outside 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').

Abstract: The invention relates to a flat contact spring for plugs of electric plug connectors with socket bodies having socket contacts.
