ABSTRACT:
The method relates to manufacturing contact spring sockets with a plurality of radially inward bowed contact springs (9) clamped at one end in an approximately cylindrical socket body (1), formed by a thin-walled deformable sleeve. The straight contact springs, formed by sections of a contact spring wire, are introduced into the socket body and made fast at their front ends to a central head (10) at the front end of a line connector (2) by deformation of the socket material. The free ends of the contact springs (9) are brought into supporting abutment on an annulus (5) at the pin insertion end. Deformation of the socket body (1) to produce bowing of the contact springs can be omitted if in accordance with the invention an insert ring (6) is introduced into the middle region of the socket body (1), which fits adjacent the interior wall of the socket, subsequently the contact springs (9) are introduced into the socket body, whereby they lie adjacent the insert ring (6), and following on this a mandrel (12), which is conically shaped and whose diameter increases towards its front end, together with the annulus (5) mounted on it, is introduced into the socket body (1) and again withdrawn from the socket body with radial expansion of the annulus (5) which is secured against axial displacement during this while carrying with it the outer ends of the contact springs, and finally the central head (10) is deformed while carrying with it inner ends of the contact springs.
