Wiring terminal and circuit breaker

Abstract

The invention discloses a wiring terminal and a circuit breaker, which relate to the electrical technical field. The wiring terminal comprise a shell, and a connecting column, a wiring clamp, an elastic sheet and a wiring board which are arranged in the shell, wherein an access channel used for wire access is arranged in the shell, the wiring board is arranged in the access channel, and the elastic sheet comprises a first elastic arm and a second elastic arm which are oppositely arranged; the first elastic arm of the elastic piece abuts against and is fixed to the inner wall of the shell, theconnecting column is in threaded connection with the wiring clamp, one end of the wiring clamp abuts against the second elastic arm of the elastic piece, and the wiring clamp can linearly move in theaxis direction of the connecting column by rotating the connecting column so that the second elastic arm of the elastic piece can tightly press the wire connected into the channel and the wiring board. The wiring terminal and the circuit breaker have the advantage of being convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a terminal block and a circuit breaker. Background technique [0002] With the increasing degree of industrial automation and the increasingly strict and precise industrial control requirements, the use of terminal blocks is becoming wider and wider, and there are more and more types. Terminal blocks are widely used in circuit design, especially in circuit breakers, and are mainly used for electrical connection of two lines to effectively ensure the stability of the connection between the two lines. [0003] However, the structure of the existing wiring terminal is relatively complicated. When assembling, the wire needs to be inserted into the installation groove first, and then fixed by a structure such as a screw. The above wiring process has many steps and poor operability, which is not conducive to industrial production. Contents of the invention [0004] The purpose o...

[0003] However, the structure of the existing terminal block is relatively complicated. When assembling, it is necessary to insert the wire into the installation groove first, and then fix it with a structure such as a screw. The above-mentioned wiring process has many steps and poor operability, which is not conducive to industrial production.
