[0002] A circuit breaker is a mechanical switching device that can close, carry, and disconnect currents under normal circuit conditions; carry a specified overcurrent within a specified time, and can close and disconnect currents under abnormal circuit conditions (such as various short-circuit conditions).

[0003] When wiring the circuit breaker, it is necessary to first insert the wire into the wiring hole of the circuit breaker, and then use an external wrench to tighten the screws on the circuit breaker to fix the connecting wire. When tightening the screws, the electrician needs to hold the wire inserted into the wiring hole with one hand and turn the screw with the other hand, which brings inconvenience to the electrician's installation work. Utility Model Content

[0004] The purpose of the utility model is to provide a circuit breaker which is convenient for wiring, so as to solve the problems existing in the above-mentioned background technology.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 As shown, a circuit breaker convenient for wiring includes a circuit breaker body 1, and wiring holes 2 for inserting wires are provided on the left and right sides of the upper and lower sides of the circuit breaker body 1. A limit plate 10 is provided in front of the top of the wiring hole 2, and a card slot 11 for limiting the wire is provided inside the limit plate 10, and a soft pad 14 is provided inside the card slot 11. The soft pad 14 is made of rubber material, so that the surface of the wire can be protected and the effect of limiting the wire can be improved. The left and right sides of the upper and lower sides of the circuit breaker body 1 are provided with a card slot 11 for limiting the wire. A force-applying structure 12 for moving the movable limit plate 10, fastening holes 3 are provided on the upper and lower sides of the surface of the circuit breaker body 1, the internal threads of the fastening holes 3 are connected with bolts 4 for limiting the wires, the outer surface of the fastening holes 3 is rotatably connected with a movable ring 5, the upper and lower sides of the surface of the movable ring 5 are fixedly connected with a fixing rod 6, the other end of the fixing rod 6 is fixed with a torsion plate 7, the surface of the fixing rod 6 is sleeved with a first spring 8, the two ends of the first spring 8 are respectively fixed between the movable ring 5 and the torsion plate 7, and a rotating block 9 is fixed to the back of the torsion plate 7.

[0023] The force-applying structure 12 includes a movable groove 121, a movable rod 122, a movable block 123 and a second spring 124. The movable groove 121 is arranged on the left and right sides of the upper and lower sides of the circuit breaker body 1. The movable rod 122 is fixed inside the movable groove 121. The inside of the movable block 123 is movably connected with the surface of the movable rod 122. The top of the movable block 123 is fixed to the bottom of the limiting plate 10. The second spring 124 is sleeved on the surface of the movable rod 122. The two ends of the second spring 124 are respectively fixed to the movable block 123 and the inner wall of the movable groove 121. In this way, when the wire is inserted into the wiring hole 2, the limiting plate 10 can be pulled forward and the movable block 123 can be driven to squeeze the second spring 124. Then the wire can be inserted into the wiring hole 2, and then the limiting plate 10 can be loosened. At this time, the second spring 124 can be used to apply elastic force to the movable block 123 and drive the limiting plate 10 to limit the wire.

[0024] Slide grooves 13 are provided on the left and right sides of the movable groove 121 , and both ends of the limiting plate 10 are movably connected to the inside of the slide grooves 13 , so that the limiting plate 10 can be auxiliary supported and its stability during movement can be maintained.

[0025] The rotating block 9 is arranged in a cross shape, and the size of the rotating block 9 is adapted to the interior of the front end of the bolt 4, so that the rotating block 9 can enter the front end of the bolt 4 to facilitate the subsequent rotation of the bolt 4.

[0026] A groove 15 is provided on the top of the limiting plate 10 , so that an electrician can apply force to pull the limiting plate 10 .

[0027] Working principle: During use, when connecting the wire to the circuit breaker body 1, the wire to be connected can be inserted into the corresponding wiring hole 2. Before insertion, the torsion disk 7 can be pressed to allow the rotating block 9 to enter the interior of the fastening hole 3 and be inserted into the interior of the top of the bolt 4. Then the torsion disk 7 is rotated, and the bolt 4 is driven to rotate together through the rotating block 9 to loosen the bolt 4. Then the limit plate 10 is pulled forward to expose the wiring hole 2 to the outside world, and the wire is inserted into the interior of the wiring hole 2. Then the limit plate 10 is loosened, and the force structure 12 is used to drive the limit plate 10 to always clamp and limit the surface of the wire. This not only reduces the trouble of the staff to hold the wire by hand, but also improves the stability after subsequent connection. After the limit plate 10 limits the wire, the electrician can press the torsion disk 7 again, and drive the bolt 4 to rotate again through the rotating block 9, so as to tighten the joint of the wire.
