Verfahren zur Herstellung von Kontaktfederbuchsen

摘要

A method relates to manufacturing contact spring sockets with a plurality of contact springs, clamped at one end in an approximately cylindrical thin-walled socket body and bowed radially inward. The straight contact springs are introduced in the socket body into the annular space between a mandrel and the socket wall and subsequently when in an aligned state relative to each other are pressed against an annular head at the front end of the line connector which partly projects into the socket body and are made fast in this position at one end. Deformation of the socket body for elastically bowing the contact springs can be omitted according to the invention, if after introduction of the contact springs into the annular space of the socket body an insert ring (10) is introduced into the latter fitting adjacent the socket innner wall, whose internal diameter is smaller than the external diameter of the annulus plus twice the diameter of the contact springs. By these means the insert ring with its inner end edges presses radially inward on the contact springs. At their ends away from the pin insertion opening they are pressed radially outwards by the subsequent introduction of the conically formed front end of the line connector, before they are made fast by clamping and folding over of the socket edge against the connector.
