Arrangement made up of at least a clamping spring and a retaining spring and a spring-force clamp for conductors
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.
1 . 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.
2 . The assembly as defined in claim 1 , wherein said contact surface comprises a stop surface between said retaining spring and said clamping spring and an adjacent region of said retaining spring over which said contact spring slides during unlocking movement.
3 . The assembly as defined in claim 1 , wherein said lubricant-containing coating has a perfluoropolyether.
4 . The assembly as defined in claim 3 , wherein said perfluoropolyether comprises more than 75 wt % of the lubricant-containing coating.
5 . The assembly as defined in claim 3 , wherein a solvent comprises less than 20 wt % of said lubricant-containing coating.
6 . The assembly as defined in claim 1 , wherein said lubricant-containing coating has a density between 1.55-1.75 g/cm 3 at 20° C.
7 . The assembly as defined in claim 1 , wherein the assembly is formed as an integral component.
8 . The assembly as defined in claim 1 , wherein the assembly is colored by annealing coloring.
