POWER CONTACT CLAMP Russian patent published in 2014 - IPC H01R13/18 

FIELD: electricity.

SUBSTANCE: female contact clamp for an electric contactor comprises at least one pair of opposite leads providing for compression of a knife-type contact with the first compressing force. Each adjacent pair of opposite leads has a groove between them and a clamping element arranged at least partially in each groove for application of the second compressing force, which is added to the first compressing force, to the adjacent pair of opposite leads. The clamping element also comprises a setting part formed by a wave-shaped bend of the clamping element. In the alternative version of the contact clamp the setting part comprises a tooth stretching downwards into the groove. The setting part limits rotation and/or longitudinal rolling of the clamp. The electrical connector comprises at least one pair of opposite legs stretching from the body part. Each leg of the pair stretches towards the contact point, in which inner surfaces of opposite legs engage. A spring clamp may be installed above one or more legs.

EFFECT: increased compressing force without thickening and expansion of a contact clamp with simultaneous provision of required permissible current load.
