[0002] A circuit breaker refers to a switching device that can close, carry, and break the current under normal circuit conditions and can also close, carry, and break the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their usage scope. The boundary between high and low voltages is relatively blurred. Generally, electrical appliances above 3 kV are called high-voltage electrical appliances;

[0003] Chinese Patent Authorization Publication No. CN216145574U discloses a circuit breaker convenient for wiring, including a body. Wiring frames are symmetrically embedded at the top and bottom of the body. Three wiring slots are equidistantly arranged at the top of the wiring frame. A transmission chamber is fixedly installed at the front end of the wiring frame through screws. The utility model can easily connect multiple wires, effectively improving the firmness of the connection and the safety of power use. The above-mentioned prior art solution has the following deficiencies: This technical solution is fixedly connected to the front docking plate in the middle through screws, and the front docking plate in the middle can be easily rotated by a cross nut, thus effectively improving the firmness of the connection and the safety of power use. However, this technical solution is relatively ordinary in the fixed clamping of wires, making it easy for wires to shake during the installation and wiring process, which will not only cause certain damage to the wires but also easily lead to problems such as poor contact. At the same time, the existing circuit breaker is directly connected to the installation surface. When maintenance is required, the entire circuit breaker needs to be removed from the contact surface, which not only takes a long time but also requires replacing too many components, increasing the maintenance cost. Therefore, we need to design a circuit breaker that is both convenient for wiring and convenient for maintenance to solve the above-mentioned problems. Content of the Utility Model

At one end of each movable block, a spring is installed, and the end of the movable block away from the spring is connected to the first clamping plate.

[0009] Preferably, the widths of the sliders are equal to the widths of the sliding grooves, and the sliders and the sliding grooves are symmetrically arranged about the central axis of the connecting plate.

[0010] Preferably, the inner sides of the second clamping plate and the first clamping plate are provided with a V-shaped clamping shape, which can clamp wires of different diameters.

[0011] Preferably, the cross-section of the anti-slip protrusions is semicircular, and the anti-slip protrusions are arranged at equal intervals on the inner sides of the second clamping plate and the first clamping plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are: This circuit breaker facilitating wiring not only realizes the function of facilitating wiring, but also realizes the function of convenient maintenance;

And with the mutual cooperation of the built-in groove and the spring, the clamping force of the second clamping plate and the first clamping plate can be buffered to prevent certain damage to the wire. At the same time, by installing a limit plate, it can play a guiding and protective role for the wire, effectively extending the service life of the wire;

[0014] (2) By installing a connecting plate, it can be slidably connected to the circuit breaker body, so that the circuit breaker body can be installed on the outside of the connecting plate. And through the movable connection between the chute and the slider, the movement range of the circuit breaker body can be guided and limited.

The widths of the slide blocks 21 are equal to the widths of the sliding grooves 13, and the slide blocks 21 and the sliding grooves 13 are symmetrically arranged about the central axis of the connecting plate 20;

[0027] Specifically, as shown in Figure 6 and Figure 7 , during use, the circuit breaker body 4 can be guided and limited by the slide blocks 21 and the sliding grooves 13;

[0028] A dust cover 1 is installed at the top end of the circuit breaker body 4, and sealing plugs 2 are evenly installed at the bottom end of the dust cover 1. Wiring grooves 3 are evenly provided at the top end inside the dust cover 1;

[0029] Built-in grooves 18 are evenly provided inside the dust cover 1 at one end of the wiring groove 3, and movable blocks 17 are installed inside the built-in grooves 18.

[0030] Specifically, as shown in Figure 3 and Figure 4As shown in the figure, when in use, through the mutual cooperation of the built-in groove 18 and the spring 19, the clamping force between the second clamping plate 11 and the first clamping plate 9 can be buffered to prevent certain damage to the wire 6.

[0031] And at one end inside the wiring groove 3, a first clamping plate 9 is installed, and a second clamping plate 11 is installed at one end of each first clamping plate 9.

[0032] The inner sides of the second clamping plate 11 and the first clamping plate 9 are provided with a V-shaped clamping shape, which can clamp wires 6 with different diameters.
