Circuit breaker terminal wire anti-loosening device

Abstract

A circuit breaker terminal line anti-loosening device belongs to the technical field of low-voltage electrical terminal connection protection. The circuit breaker terminal line anti-loosening device comprises a peripheral base, a connecting plate moving guide mechanism, a line active anti-loosening frame and a line driven anti-loosening frame. The peripheral base is in the shape of a mouth character. The connecting plate moving guide mechanism is arranged on the right end of the peripheral base towards the upper side. The line active anti-loosening frame is in the shape of a H character. The lower side of the line active anti-loosening frame is connected with the upper side of the peripheral base to form a sliding pair, and is connected with the connecting plate moving guide mechanism to form a meshing pair. The line driven anti-loosening frame is arranged in the line active anti-loosening frame. The device can avoid loosening or even disconnection caused by vibration, pulling and the like, thereby avoiding subsequent troubleshooting troubles and wasting troubleshooting time, and fully protecting the reliability and stability of electrical connection and the safety of equipment and personnel.
