Electromagnetic contactor with sliding guide

摘要

An electromagnetic contactor includes a pair of fixed contact portions having a predetermined distance from each other; a movable contact including a pair of movable contact portions disposed facing the pair of fixed contact portions; a movable support body supporting a central portion of the movable contact in an extending direction of the movable contact; a housing receptacle formed from a non-conductive body, housing at least the pair of fixed contact portions and the movable contact; an electromagnet unit causing the movable support body to move back and forth to cause the movable contact portions to contact to and separate from the fixed contact portions; and sliding guides extending along a moving direction of the movable contact for moving the movable contact back and forth in the housing receptacle to regulate a turning displacement of the movable contact. The sliding guides are different from the housing receptacle.

主权项

1. An electromagnetic contactor comprising:
a pair of fixed contact portions disposed to be separated a predetermined distance away from each other; a movable contact extending in a separating direction of the pair of fixed contact portions, and including a pair of movable contact portions disposed facing the pair of fixed contact portions on two end portion sides thereof; a shaft shaped movable support body supporting a central portion of the movable contact in an extending direction of the movable contact; a housing receptacle formed from a non-conductive body, housing at least the pair of fixed contact portions and the movable contact; an electromagnet unit causing the movable support body to move back and forth to cause the movable contact portions to contact to and separate from the pair of fixed contact portions; and sliding guides extending along a moving direction of the movable contact for moving the movable contact back and forth in the housing receptacle to regulate a turning displacement of the movable contact, wherein the sliding guides are different from the housing receptacle, and each of the sliding guides includes two end portions in an extending direction of the sliding guide formed from a material having spring properties supported by the housing receptacle.
