Title:
INTERLOCKING COMPONENT AND CIRCUIT BREAKER
Document Type and Number:
Japanese Patent JP2017216165
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an interlocking component capable of ensuring stable and reliable interlocking of contact opening operation in respective poles, even after long term use, and to provide a circuit breaker including that interlocking component.SOLUTION: An interlocking component for interlocking contact open/close means including resilient force accumulating means accumulating resilient force for opening the contact, and trip means for acting on the contact open/close means to release the resilient force, has a drive part being driven by abutting against a part of the contact open/close means when the resilient force accumulating means is releasing resilient force, and a transmission part for transmitting the resilient force received by the drive part to the trip means, where the impact mitigation means transmission part includes impact mitigation means for mitigating the impact by the resilient force.SELECTED DRAWING: Figure 1
