A wiring device applied to a circuit breaker

Abstract

The invention discloses a wiring device applied to a circuit breaker, comprising: a housing frame, which includes a pair of longitudinal side plates parallel to each other and a pair of transverse side plates parallel to each other, the four together form a frame structure, One of the longitudinal side plates is provided with a threading opening, and the wires can be passed through the inside of the housing frame from the wiring opening; the electric connection part, which includes a contact head located inside the housing frame, is fixed on the The connecting part of the outer end of the contact head passing through the other longitudinal side plate, and the contact piece fixed on the outer end of the connecting part; ends extending into the interior of the housing frame. The invention can ensure fast installation and fixation of electric wires on the wiring device, and can prevent the defect of loose wire ends.

Description

technical field [0001] The invention relates to the technical field of power distribution, in particular to a wiring device applied to a circuit breaker. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Commonly used circuit breakers generally include a housing, terminal posts located at both ends of the housing, and contact groups located inside the housing, overload protection bimetallic strips, trip units, arc extinguishing systems, operating mechanisms and other components. The two binding posts at both ends are used to connect two lines respectively, and the opening and closing control of the lines is formed through the circuit breaker in the middle. [0003] However, the existing terminals generally only use a horizontal screw to squeeze and fix the wire ends inserted into the int...

Problems solved by technology

[0003] However, the existing terminals generally only use a horizontal screw to squeeze and fix the wire ends inserted into the interior of the terminal. This simple extrusion fixing method is prone to the risk of loosening or even falling off of the wire ends; therefore, operators must use Tighten screws with greater force to provide high extrusion force and anti-slip friction

However, this process not only cannot completely eliminate the risk of thread loosening, but also takes time and effort, damages the screwdriver, and even easily damages the internal structure of the circuit breaker due to misoperation
