Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a wiring terminal block for a circuit breaker. Background Art

[0002] Terminal blocks are an accessory product used to achieve electrical connections, and are classified as connectors in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks has gradually increased. With the development of the electronics industry, the use of terminal blocks has become more and more diverse; in addition to PCB board terminals, the most widely used ones include hardware terminals, nut terminals, spring terminals, and so on.

[0003] After the terminal block is installed on the circuit breaker, when connecting the wire harness, the protruding part of the elastic clip on the wire harness is usually embedded in the terminal block for fixing. As a result, when the wire harness is removed later, it is necessary to use a tool to push the protruding part of the elastic clip out of the terminal block and then pull out the wire harness, which is more troublesome. In view of this, we propose a terminal block for a circuit breaker. Utility Model Content
