ABSTRACT:
A process for the production of contact-spring bushes with a plurality of contact springs curved radially inwardly and clamped on one end in an approximately cylindrical bush body. Initially straight contact springs formed by portions of a contact-spring wire are first introduced into the interior of the bush body and are subsequently, on the one hand, pressed against an annular extension partially projecting into the bush body and located at the front end of a line connection piece and fixed in this position on one end and, on the other hand, elastically deformed radially, in such a way that their other ends facing the pin insertion end of the bush body are guided so as to be freely movable in an annular gap provided between the bush body and an annular body provided in it. Contact-spring bushes of particularly small dimensions can be produced in a simple way when, after the contact springs have been introduced into the bush body which is formed by a thin-walled deformable sleeve, the bush body is provided from the outside, at each of two locations offset axially in relation to each other and the ends of the bush body with an annular bead projecting radially inwards, these engaging the contact springs and providing them with the curvature directed radially inwards.
