Document Type and Number:
WIPO Patent Application WO/2017/206581
Kind Code:
A1
Abstract:
A moving contact operating mechanism for a miniature circuit breaker, comprising a moving contact energy storage apparatus (11). The moving contact energy storage apparatus comprises an energy storage rotating member (111) and an energy storage abutting rod (112). The energy storage rotating member is provided with a first extension arm (1111) and a second extension arm (1112). A rotating sleeve on a handle (1) is provided with an elongated recess (1A). An end portion of the first extension arm is provided in the elongated recess. An end portion of the second extension arm is hingedly connected to an upper end portion of the energy storage abutting rod. The energy storage rotating member rotates to drive the second extension arm to swing, thereby vertically moving the energy storage abutting rod. The moving contact operating mechanism can reduce the length or the width of an earth-leakage circuit breaker.
