[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figure 1-Figure 3 As shown, a circuit breaker convenient for wiring consists of a circuit breaker body 1, a wiring pressing groove 2 and a sector block 3;

[0018] The upper and lower ends of the front side of the circuit breaker body 1 are provided with wiring pressing grooves 2, with two wiring pressing grooves 2 set at each end. The inner groove wall of the wiring pressing groove 2 is provided with a rotating shaft hole groove, and the sector block 3 is rotatably installed in the rotating shaft hole groove through the sector shaft 4;

[0019] A spring-loaded cavity 6 is provided in the circuit breaker body 1, into which a limiting plug 10 is inserted. One end of the limiting plug 10 extends into the wiring pressure groove 2 and is connected to a one-way inclined plug 9. A limiting spring pressure ear 8 is fixedly mounted on the limiting plug 10 in the spring-loaded cavity 6. The limiting spring pressure ear 8 can slide horizontally in the spring-loaded cavity. A spring 7 is pressed on the side of the limiting spring pressure ear 8 away from the one-way inclined plug 9, which keeps the one-way inclined plug 9 in an extended state.

[0020] The sector block 3 is provided with a plurality of arc-shaped press-set limiting holes 5 , and the one-way inclined plug 9 is inserted into any press-set limiting hole 5 to fix the sector block 3 .

[0021] like Figure 1-Figure 3As shown, the present invention also discloses the following multiple more optimized specific structures:

[0022] A connecting metal pressing piece 14 is embedded and fixed on the inner pressing surface of the sector block 3. The connecting metal pressing piece 14 is used to press the incoming and outgoing wires of the circuit breaker to achieve electrical connection.

[0023] One end of the limiting plug post 10 extends to the outside of the circuit breaker body 1 and is installed with an installation cap 11. The installation cap 11 is mainly used to pull out the sector block 3 before wiring.

[0024] A mounting back groove 13 is provided on the back side of the circuit breaker body 1 , and the mounting back groove 13 is used for mounting on a fixed groove rail.

[0025] Two adjacent sector blocks 3 are connected together through a sector block linkage frame 12 to facilitate simultaneous pressing.

[0026] like Figure 1-Figure 3 When wiring the circuit breaker shown as being easy to wire, first pull out the installation cap 11 to rotate the sector block 3 out, then insert two wires into the two wiring pressing grooves 2 on the same end side of the circuit breaker body 1 at the same time, peel the insertion part of the wire, and rotate and press the two sector blocks 3 through the sector block linkage frame 12 until the connecting metal pressing piece 14 is pressed onto the wire. Then, continue to press hard to make it slightly deformed, so that the one-way inclined plug 9 can be inserted into the corresponding pressing limit hole 5. The position of the pressing limit hole 5 for different wire thicknesses is different.

[0027] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only for explaining the principles of the present invention.
