Description

Terminal Blocks for Circuit Breakers

technical field

The utility model relates to a circuit breaker component, in particular to a connection terminal for a circuit breaker.

Background technique

The circuit breaker has a main circuit and an auxiliary circuit. The main circuit is a circuit that is connected to complete the main functions of the circuit breaker, and the auxiliary circuit refers to the circuit that completes the auxiliary functions of the circuit breaker. Since the auxiliary function is set by the user according to the different needs of the user, in order to facilitate the user to directly use the auxiliary circuit wiring, the circuit breaker is often equipped with a terminal block.

Generally, circuit breaker terminals are divided into two types: integrated type or split type:

The integrated type means that all the terminals are fixed in a base. The advantage of this form is that it is convenient for the user to install the terminals in the circuit breaker, but the disadvantage is that the terminals are pre-made, so the number of terminals It is fixed and cannot be adjusted according to the needs of users. When users want to change the number of terminals, they have to replace all the terminals, which causes unnecessary waste and reduces the interchangeability of circuit breakers.

The split type includes two structures, one refers to the connection terminals are divided into several groups, and each group consists of seven to eight terminals. Adding one group will increase seven to eight terminals, which cannot satisfy the needs of users well. The other split type refers to that the terminal block is composed of pieces assembled. The advantage of this form is that it can be assembled according to the needs of users. Although it solves the problem that the number of terminal blocks cannot be replaced on demand due to the integrated type, its disadvantages are Its wiring direction is consistent with the direction of the installation guide rail, that is to say, when the user installs the terminal block in the horizontal direction, it must be connected in the vertical direction of the circuit breaker. If the circuit breaker is installed in the switch cabinet, it must be connected in the switch cabinet. There is a large space above for the circuit breaker to facilitate the user's wiring, which will inevitably increase the volume of the switch cabinet; if the user wants to connect the circuit breaker directly in front of the circuit breaker, it is necessary to install it by turning the mounting bracket or guide rail by 90° by adding auxiliary parts , not only hinders the overall structure of the circuit breaker, but also destroys the appearance of the circuit breaker.

Therefore, there is a need for a circuit breaker that can not only overcome the above-mentioned shortcomings of the traditional terminal blocks with complex structures and the number of terminals cannot be replaced according to user needs, but also reduce the size and make the circuit breaker look beautiful.
