Abstract: A method for producing contact jacks for electric plug-in connectors.

Abstract: A plug socket for establishing a high-current electrical connection and including a metal body formed along a portion of its longitudinal extent as a hollow cylinder section, and a contact spring jack received in the hollow cylinder section and having a plurality of linear, substantially hyperbolically extending, contact elements connected at their opposite ends by respective circumferential material bands, with the contact spring jack being anchored, at its rear, with respect to a plug-in direction of an associated contact pin, end in the hollow cylinder section with a press fit, and with its front, in the plug-in direction of the associated contact pin, end forming a sliding fit connection with the hollow cylinder section.

Abstract: A circular plug and socket connector is introduced for producing electrical line connections. In the region of one of its ends it includes a housing, accommodating and holding an insulating base as contact carrier and, in the region of its other end, is includes a sealing cable lead-in and a coupling ring, which makes a screwed connection with a second plug and socket connector half of complementary construction and is mounted rotatably on the outer periphery of the housing and secured against being pulled off in the axial direction and a covering cap fixed mechanically to the housing.

Abstract: For a readily manufactured configuration of contact plugs for electrical plug connectors, which consists of a stable sleeve body, formed from a sheet material, and a contact spring plug, lying in this sleeve body and having a plurality of contacting means, such as contacting wires or contacting strips in linear or strip-shaped contact with a contact pin, which is to be introduced into the plug, it is proposed that the sleeve body be provided with at least one projection, which is directed transversely to the longitudinal axis of the contact plug and formed by at least one stamping and is in positive engagement with one of the two edge strips of sheet material, connecting the contact wires or contact strips of the contact spring plug with one another.

Abstract: A circular plug and socket connector is provided for producing electrical line connections and comprises a housing, accommodating and holding, in the region of one of its ends, an insulating base as a contact carrier and, in the region of its other end, a sealing cable lead-in and a covering cap, which makes a screwed connection with a second half of a covering ring of complementary configuration and is mechanically fixed to the housing. The housing has an overall cylindrical external periphery with at least one bearing surface assigned to the coupling ring and is overlapped, in part by the coupling ring and in part by a pot-shaped handle part having an opening in its bottom for the introduction of a cable.

Abstract: An angular plug support having a socket part an angular support part having a first limb for receiving a contact-retaining insulator, and a second limb overlapping the socket part with a possibility of rotation relative thereto but without a possibility of an axial displacement relative thereto, and a locking device provided in a region of an overlapping of the socket part by the second limb for securing the angular support part in its selected rotational position with respect to the socket part and including a plurality of rigid flat surfaces provided on an outer periphery of the socket part or an inner periphery of the second limb, and a respective plurality of radially spring-biased surfaces provided at another of an outer periphery of the socket part and the inner periphery of the second limb.
