DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 As shown, a structure of a wire-pressing and deformation-preventing terminal for an intelligent circuit breaker according to an embodiment of the present utility model includes a circuit breaker housing 1. A handle 10 is provided on the left side of the circuit breaker housing 1. The handle 10 extends through the circuit breaker housing 1 to control the opening and closing of the circuit breaker. Two wiring holes 2 are correspondingly formed on the left side of the circuit breaker housing 1. A fastening hole 20 is provided on one side of each wiring hole 2. A receiving cavity 3 is formed inside the circuit breaker housing 1 at each wiring hole 2. A conductive sheet 30 is disposed in the receiving cavity 3. A wire-pressing block 4 is movably disposed inside the receiving cavity 3 on the inner side of each fastening hole 20. A fastener 21 for controlling the wire-pressing block 4 to press or loosen the wire is threadedly connected in the fastening hole 20.

[0022] During use, when wiring, the wiring end of the wire is passed through the wiring hole 2 and extends into the receiving cavity 3. At this time, the wire is located between the conductive sheet 30 and the wire-pressing block 4. Then, the fastener 21 in the fastening hole 20 is tightened. When the fastener 21 is in a tightened state, it causes the wire-pressing block 4 to press the wire. The wire-pressing block 4 presses the wire against the conductive sheet 30 to complete the pressing and fixing of the wire, ensuring a firm connection of the wire, avoiding the wire from falling off during use, and at the same time avoiding the wire from being deformed under pressure. When the wire needs to be disassembled, the fastener 21 can be unscrewed.

[0023] The wire-pressing block 4 includes a rotating part 40, a wire-pressing part 41, and a matching part 42. The rotating part 40 is formed with a pivot 43, and the wire-pressing block 4 is rotatably disposed in the receiving cavity 3 through the pivot 43. The wire-pressing part 41 is formed with a plurality of pressing teeth 44 and an anti-warping pressing part 46. The matching part 42 is an inwardly concave arc structure. A protective frame member 45 is further disposed in the receiving cavity 3, and the protective frame member 45 is provided with a matching hole at the pivot 43.

[0024] During use, when the fastener 21 is tightened, it contacts the matching part 42, causing the wire-pressing block 4 to rotate counterclockwise around the pivot 43. The wire-pressing block 4 rotates and the wire-pressing part 41 contacts the wire. The pressing and fixing of the wire are achieved through the cooperation between the wire-pressing part 41 and the wire. Each pressing tooth 44 ensures a stable pressing of the wire, and the anti-warping pressing part ensures that the wire is pressed without warping, preventing the wire from deforming and at the same time increasing the contact area between the wire-pressing block 4 and the wire. The matching part 42 adopts an arc structure to ensure the smoothness of the cooperation between the fastener 21 and the wire-pressing block 4, avoiding jamming between the two. Further, by providing the protective frame member 45, the terminal components in the receiving cavity 3 are protected, improving the use safety of the product.

[0025] The terminal of the conductive sheet 30 is formed with a clamping portion 31, and a clamping groove 32 adapted to the clamping portion 31 is formed in the accommodating cavity 3; a plurality of anti-slip grooves 33 are arrayed on the corresponding side of the terminal of the conductive sheet 30 and the pressing block 4.

[0026] During use, the cooperation between the clamping portion 31 and the clamping groove 32 ensures the installation stability of the conductive sheet 30, and the surface roughness when the conductive sheet 30 contacts the wire is increased by providing the anti-slip grooves 33, further improving the pressing and fixing effect on the wire.

[0027] It should be noted that the number of fastening holes 20 and wiring holes 2 of the present utility model is two respectively. The two wiring holes 2 and the two fastening holes 20 are rectangular and cross each other in pairs. The above distribution method can effectively increase the phase distance between the two wiring holes 2, increase the creepage distance, and thus improve the use safety of the product.

[0028] At the same time, it should be pointed out that the terms used in the present utility model, such as: "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model.

[0029] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches should also be regarded as the protection scope of the present utility model.
