Abstract
An assembly for contacting an electrical conductor includes a clamping spring which acts as a pressure spring for fixing an electrical conductor in a spring-force clamp and a retaining spring for locking the clamping spring in an open position such that the conductor can be introduced into a contact region in a shifting direction. The clamping spring touches the retaining spring along a contact surface in a locked state and during movement from the locking state into a unlocking state. A lubricant-containing coating is arranged on at least the contact surface.
Claims8
An assembly for contacting an electrical conductor, comprising
- (a) a clamping spring for connecting an electrical conductor in a spring-force clamp;
- and
- (b) a retaining spring for locking the clamping spring in an open position such that a conductor can be introduced into a contact region in a shifting direction, wherein said clamping spring touches said retaining spring along a contact surface in a locked state and during the movement from the locking state into an unlocking state;
- and
- (c) a lubricant-containing coating arranged on at least said contact surface, wherein said retaining spring comprises an uncoated surface adjacent to said contact surface, said uncoated surface having a higher coefficient of friction than said contact surface.
