CONDUCTIVE BASE AND CONTACT MODULE OF AIR CIRCUIT BREAKER Russian patent published in 2010 - IPC H01H1/58 H01R9/24 

FIELD: electricity.

SUBSTANCE: discloses conductive base and contact module of air circuit breaker. Connector of conductive base has curvilinear surface arranged on lateral side of its end part, and is connected by means of teethed joint to contactor of contact module, and contactor of contact module has another curvilinear surface, which corresponds to curvilinear surface of connector, and is elastically supported in vertical direction by means of flat spring so that both end parts of contactor execute vertical elastic motion versus longitudinal axis of contactor.

EFFECT: increased service life of conductive base and contact module due to prevention of damages caused by mechanical collision of conductive base connector with contactor of contact module, which occurs when polar tip of circuit breaker is inserted into contact module.
