Abstract: A socket contact (1) has a hollow cylindrical contact wire region (AB) for receiving a stripped end portion of an electrical conductor to be connected, and a hollow cylindrical contact region (KB) with a pin insertion opening (2) for receiving a contact pin. The contact region (KB) has a cylinder wall with at least one radially inwardly folded contact blade (4), the free end of which points towards the pin insertion opening (2). The cylinder wall has an at least partially circumferential groove (5) for the contact blade in the region of the fold.

Abstract: A contact spring assembly for the self-locking contacting of a wire (28) of an electrical conductor includes a support wall (24) made of a conductive material and a contact spring (10). The contact spring (10) has a base leg (20) held stationary with respect to the support wall and a clamping leg (18) which, together with the support wall (24), forms an insertion receptacle (26) for the wire (28) of the conductor. The insertion receptacle is tapered in the insertion direction. The base leg (20) of the contact spring transitions into a holding leg (22? 22?), which is inserted into a receiving shaft (30) stationary with respect to the support wall (24) and has two detent projections (38), which protrude perpendicularly to the base leg in opposite directions and are locked to mating contours (34) on the walls of the receiving shaft.

Abstract: An electrical contact element is provided which particularly has a lead content of less than or equal to 0.1% by weight. The contact element has at least one first region and at least one contiguous second region, and an at least partly peripheral groove is provided between the first region and the second region. The contact element can thus be produced without burrs.

Abstract: The invention relates to a socket contact for electrically contacting a pin contact, wherein the socket contact (1) is substantially formed from a hollow cylinder, into which at least one axial slot (3) is introduced, as a result of which at least two spring arms (4) are formed, wherein the ends of the spring arms (4) have contact regions (4b), wherein in each case two touch contacts (7) with the pin contact can be produced via the contact regions (4b), wherein the contact regions (4b) have a curved cover area (4c), wherein the curved cover area (4c) forms two touch contacts (7) with the pin contact.
