Abstract: In a flat contact socket with two spring contact arms elastically touching at a distance from the free ends over part of their length, arranged on the socket body and bent back at the free ends, and with outer springs supported on the contact arms or the purposes of easy and secure insertion of the flat contact socket into the socket housing, the socket body is firmly surrounded by an outer spring body and the outer spring body is provided at the diameter wall sections with arm parts, extending over the flat sides of the contact arms and obliquely to the free ends and to one another. In addition, the free ends of the arm parts are bent back over part of their length over the free ends of the contact arms against one another and in the insertion direction and arranged to press against the free ends of the contact arms.

Abstract: A multiterminal electric coupling device having a longitudinally-extending plug element including a plug housing with grooves on one end thereof and plug contacts contained within the plug housing. A longitudinally-extending socket element is provided and includes a socket housing with longitudinally-extending grooves and socket contacts contained within the socket housing. A hook-pin hinge is provided at one end of the housings for flexibly connecting the housings together. A longitudinally-extending slider is provided and has an interior and exterior sides and longitudinally-extending interior facing strips. The strips are locatable in the socket housing grooves at an end remote from the hook-pin hinge to allow for guided movement of the slider in the longitudinal direction with respect to the socket element.

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: In order to improve the stability of a flat contact spring for plugs of electrical plug and socket connections which comprise connections for electrical conductors and a recess the marginal faces of which support a retaining tongue fastened to the spring housing, the contact spring is formed from a sheet metal cut-out with a first section composed of a central strip and longitudinal marginal strips which can be folded back onto the latter. The longitudinal marginal strips comprises cut-outs which extend as far as their edges and which together form an undercut recess when the longitudinal marginal strips are folded back onto the central strip.

Abstract: In an electrical coupling device with one contact strip firmly secured, for example, to the frame of the unit, and with one socket strip lodged in a housing, and with means for preventing incorrect coupling, in order to achieve easy and safe connection, the socket strip housing is fitted to the frame by a pivot pin arranged at one end of the housing and has a slide groove in at least one lateral longitudinal wall. By displacing in the slide groove a sliding block carried by means of a lever hinged to the frame, the socket strip housing can be pivoted and locked in order to permit coupling of the strip contacts and socket contacts to the contact strip.

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