A Spring Clamp Termination Device For Dc Control Electromagnetic

A Spring Clamp Termination Device For Dc Control Electromagnetic Contactors

Abstract: The present invention relates to a spring clamp termination for power and control contactors. The device comprises housing having rear and front portions (2,1) comprising fixed and moving contact assemblies (17 & 18). Plurality of clamp means (11) are operatively attached to the fixed contact assembly (17) wherein the clamp means (11) are multi-profiled suitably securing conductor. Cam assembly (15) is in co-operative engagement with said clamp means (11) to establish plurality of states of operations and comprises actuating means (29) whose co-operation with clamp means (11) provides a relative biased movement of the cam assembly (15) with respect to the clamp means (11) such that center of gravities of cam (15) and clamp means (11) are suitably aligned to a predetermined angular position. Plurality of coil terminals are extremely locate on the contact assemblies.
