ABSTRACT OF THE DISCLOSURE The method relates to manufacturing contact spring sockets with a plurality of radially inward bowed contact springs (6) clamped at one end in an approximately cylindrical socket body (1), formed by a thin-walled deformable sleeve. After introduction of the straight contact springs (6), formed by sections of a contact spring wire, 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 (5). This is associated with a mandrel for assisting assembly, which passes through it and which is during the manufacture introduced co-axially into the socket body and finally withdrawn from it. Deformation of the socket body to bow the contact springs can be omitted, if in accordance with` the invention firstly the thin contact springs (6) with a diameter of maximally 0.2mm after introduction into the socket body (1), whereby their front ends enter a co-axial annular gap between the socket inner wall and the central head (7) of the line connector (2) which projects into the socket interior, are made fast in a position approximately parallel to the axis by deformation of the head (7). Subsequently the mandrel (10) together with the annulus (5) is introduced into the socket body (1). The contact springs (6) 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 (10). Thereafter the mandrel is withdrawn from the socket body until relaxation of the permanently deformed contact springs and the annulus (5) is held fast in its position in the socket body by folding over of the socket body edge.
