ABSTRACT:
The method relates to manufacturing contact spring sockets with a plurality of radially inward bowed contact springs clamped at one end in an approximately cylindrical socket body, formed by a thin-walled deformable sleeve. After introduction of the straight contact springs into the socket body from one socket end, they are made fast by deformation of the socket material and their free ends are brought into supporting abutment on an annulus. This is associated with a mandrel for assisting assembly, which passes through it and which is during manufacture introduced co-axially into the socket body and finally withdrawn from it. Subsequently the mandrel together with the annulus is introduced into the socket body. The contact springs are then, by applying axial pressure on their ends, converted into a shape bowed into the interior of the socket until they abut the mandrel. Thereafter, the mandrel is withdrawn from the socket body with relaxation of the permanently deformed contact springs and the annulus is held fast in its position in the socket body by folding over of the socket body edge.
