ABSTRACT:
In the case of a plug contact which consists of an electrical contact body (11) and of a spring sleeve (12) with a longitudinal joint (43), encompassing said contact body on the outside, the fixation of the spring sleeve on the contact body has been solved as follows: The portions of the spring sleeve (12) adjoining the longitudinal joint (43) each have a perforation (51) with which an anchoring cam (53) of the contact body (11) projecting to the outside is in locking engagement. Between each perforation (51) and the longitudinal joint (43), there is a hold back bridge (55) which, in cooperation with the adjacent anchoring cams (53), firmly holds the spring sleeve (12) tensed in flush contact along the periphery of a cylindrical portion of the contact body (11). For the manufacture of the plug contact, a sheet metal blank for the spring sleeve (12) is bent into a U-shape, the U-bridge and U-legs of which each run along a circular arc over about 120.degree. and with a curvature adapted to the periphery of the contact body (11). The contact body (11) provided with the anchoring cams (53) is inserted into the U-shape in such a way that the anchoring cams (53) face away from the U-bridge. Then, the U-legs are forced laterally against the contact body (11), whereby the hold back bridges (55) are moved over the anchoring cams (53) and are brought into locking engagement with the latter.
