ABSTRACT:
The invention relates to a connector comprising a housing, a spring biased contact surface facing in a front direction of said connector for establishing a contact with a connector counterpart, said contact surface being movable within a working area against a spring force from a first rest position to a second connecting position by a force directed to the contact surface upon establishing a contact with the connector counterpart. In order to achieve a connector which makes it possible to keep the contact force at an appropriate and substantially constant level, said connector comprises a rolled spring with an outer end protruding in said front direction of said connector; said protruding end is attached to the housing of said connector, whereby said rolled spring is at least partly unrolled when said contact surface is moved against the spring force.
