Title:
A manufacturing method of a molded case circuit breaker and its pin for opening-and-closing mechanisms
Document Type and Number:
Japanese Patent JP6018144
Kind Code:
B2
Abstract:
A circuit breaker according to the present disclosure may include a movable contact (20) configured to be brought into contact with or separated from a stationary contact (10); and a switching mechanism (30) configured to switch the movable contact (20), wherein the switching mechanism (30) includes a shaft (74) rotatably installed therein; a transfer link (90) configured to transfer a driving force from the shaft to the movable contact; and a pin (180, 280) configured to hinge-couple the shaft to the transfer link and insulate them from each other, and the pin is installed with a wear resistant member (184) at a portion brought into contact with the shaft. Meanwhile, a method of fabricating a pin for a circuit breaker switching mechanism may include forming an insulating member in a cylindrical shape; forming a wear resistant member in a pipe shape capable of surrounding one side of the insulating member; disposing the wear resistant member at one side of the insulating member; and deforming both ends of the wear resistant member to burrow into the insulating member so as to fix the wear resistant member to one side of the insulating member.
