Magnet and movable contact support structure for a multiple contact electromagnetically actuated switch

Abstract

Abstract A MULTIPLE CONTACT ELETROMAGNETICALLY ACTUATED CONTACTOR HAVING A BELL CRANK CONNECTION BETWEEN A MAGNET ARMATURE AND A MOVABLE CONTACT CARRIER. THE CONTACTOR INCLUDES AN ARRANGEMENT WHEREBY THE ELECTROMAGNET AND THE CONTACTS ARE ENCLOSED IN SEPARATE HOUSING. THE HOUSING FOR THE CONTACTS INCLUDES AN INSULATING BASE AND A BARRIER WHICH ACTS AS A COVER FOR THE BASE AND COOPERATES WITH THE BASE TO PROVIDE A ROW OF COMPARTMENTS. EACH OF THE COMPARTMENTS HAS A PAIR OF STATIONARY CONTACTS AND A MOVABLE CONTACT THEREIN AND THE WALLS OF THE COMPARTMENTS PROVIDE A HIGH DEGREE OF INTERPHASE ISOLATION BETWEEN THE CONTACTS IN ADJACENT COMPARTMENTS. THE MOVABLE CONTACTS ARE OPERATED BY A U-SHAPED CONTACT CARRIER THAT IS MOVABLE IN A SLOT IN A REAR WALL OF THE BASE AND HAS PORTIONS EXTENDING THROUGH OPENINGS IN THE REAR WALL INTO THE COMPARTMENTS. THE CONNECTION BETWEEN THE BELL CRANK AND CONTACT CARRIER IS ARRANGED SO THAT THE BARRIER CAN BE REMOVED WHEN THE CONTACTS ARE SECURELY WELDED TOGETHER AND WILL CAUSE THE MOVABLE CONTACTS TO SEPARATE FROM THE STATIONARY CONTACTS DURING LIGHT WELDS BETWEEN THE CONTACTS.
