気中遮断機のフィンガーモジュール
Document Type and Number:
Japanese Patent JP5031856
Kind Code:
B2
Abstract:
Disclosed therein are a conductor base (1) and a finger module (300) of an air circuit breaker. Since the connector (200) of the conductor base has the curved surface (220) formed on a side of an end portion thereof and tooth-coupled with the contactor (310) of the finger module (300), the contactor of the finger module has another curved surface (311) corresponding to the curved surface of the connector and the contactor is elastically supported in a vertical direction by the plate spring (330) to allow both end portions of the contactor to perform a vertical elastic movement relative to a longitudinal center of the contactor, the present invention can prevent damages due to a mechanical impact between the connector of the conductor base and the contactor of the finger module, which may occur while the breaker terminal is inserted into the finger module, to thereby extend the lifespan of the conductor base and the finger module.
