Small-size circuit breaker with insertion conductive clamp

Abstract

The invention discloses a small-size circuit breaker with an insertion conductive clamp. The small-size circuit breaker with insertion conductive clamp comprises a circuit breaker body and an insertion conductive clamp, wherein the circuit breaker body comprises a shell, an operating mechanism, a conductive clamp assembly, an arc extinguishing chamber, an electromagnetic system and a contact mechanism, wherein an insertion groove is formed in an incoming line end of the circuit breaker body and is used for a copper bar of a power distribution board to insert, an insertion conductive clamp is arranged in the insertion groove and comprises a conductive clamp body and a static contact plate, the static contact plate is connected with an upper end of the conductive clamp body, the conductive clamp body comprises a connection part and elastic clamping arms, the elastic clamping arms extend towards an inlet of the insertion groove, the two elastic clamping arms are arranged and are fixedly connected with two ends of the connection part, expansion parts are arranged at lower ends of the elastic clamping arms, and an U-shaped clamp spring sheet sleeves an outer wall of an upper end of theconductive clamp body and is used for clamping the elastic clamping arms. The invention aims to provide the small-size circuit breaker with the insertion conductive clamp, and the small-size circuit breaker can be convenient to install, is rapid in reaction speed and high in safety and is convenient and practical.

Description

technical field [0001] The invention relates to a small circuit breaker with a plug-in conductive clip. Background technique [0002] At present, the vast majority of ordinary small circuit breakers use column type terminals for wiring, the wiring efficiency is relatively low, and after the product is used abnormally, it is relatively inconvenient to replace and disassemble, and screwdrivers and other tools are required to terminate the incoming and outgoing wires and loosen the wires. can be realised. Contents of the invention [0003] The purpose of the present invention is to provide a small circuit breaker with a plug-in conductive clip, which can be easily installed, has fast response speed, strong safety, and is convenient and practical. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a small circuit breaker with a plug-in conductive clip, including a circuit breaker body and a plug-in conductive clip, and t...
