SI3123566T1 - Socket contact for an electrical socket - Google Patents

Abstract

The invention relates to a contact socket (1) for power outlets (9a) or couplings comprising two resilient socket arms (2a, 2b) which form an insertion opening (3) and between which a contact pin (10) of a plug is to be clamped such that the two socket arms (2a, 2b) are parted by resilient deflection when the contact pin (10) is introduced perpendicular to the deflection plane into the insertion opening (3). The contact socket (1) has a fork (12) comprising a first and a second outer arm (4a, 4b) between which a first and a second inner arm (5a, 5b) is formed, wherein the inner arms are in each case disposed on the free ends (6a, 6b) of the outer arms and a free end of each inner arm forms one of the socket arms, wherein between the socket arms and the outer arms free regions (F, F') are formed, such that when the contact pin is introduced into the insertion opening the two socket arms can be deflected resiliently outwards into the free regions. Between the socket arms and the outer arms, in particular on the first and/or the second outer arm, at least one limit is formed which limits the deflection of the first and/or second socket arm.

The contact sleeve (1) according to one of the claims 1 or 2, wherein the arms (2a, 2b, 4a, 4b, 5a, 5b) and the spring back portion (14) are bent from one longitudinal piece of sheet metal. The contact sleeve (1) according to one of the claims 1 or 2, wherein a connecting element (8) is provided between the first and second outer legs (4a, 4b), which connects the first outer leg (4a, 4b) to the other. The contact sleeve (1) according to claim 4, wherein the connecting element (8) is anchored to the first and second outer leg (4a, 4b). The contact sleeve (1) according to claims 2 and 4, wherein the spring back portion (14) is so formed that it includes the connecting element (8). The contact sleeve (1) according to one of claims 4 to 6, wherein the connecting element (8) is fixed to at least one of the restriction features (7, 7 '). The contact sleeve (1) according to one of claims 4 to 7, wherein the connecting element (8) is designed as an electrical connection element. The contact sleeve (1) according to one of the claims 1 to 8, wherein at least one of the two arms (2a, 2b) of the sleeve is so formed that the insertion opening (3) is conical or in the form of a funnel. A coupling or socket (9a) with a contact sleeve (1) according to one of claims 1 to 9. A coupling or socket (9a) with a contact sleeve (1) according to one of the claims 1 to 8, wherein the first and second outer leg (4a, 4b) are at least partly attached to the connection or sockets (9a) and are the first second the inner leg (5a, 5b) is spring-loaded.
