[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0018] Please refer to Figure 1-2 As shown, a positioning structure of the cabinet 2 of a 5G1U circuit breaker in an embodiment of the present utility model includes a circuit breaker body 1 and a cabinet 2. The interior of the cabinet 2 is hollow and formed with an assembly cavity 20. One side of the assembly cavity 20 has an assembly opening 21. A plurality of slots 22 are equidistantly and arrayed on the inner wall of one long axis side of the assembly opening 21. An assembly part 10 adapted to the slots 22 is formed on the outer side wall of the circuit breaker body 1.

[0019] During assembly, align the circuit breaker body 1 with the assembly opening 21, and align the assembly part 10 outside the circuit breaker with the slots 22 inside the assembly opening 21. Then, push the circuit breaker into the assembly cavity 20 along the assembly opening 21 to complete the assembly of the circuit breaker body 1 and the cabinet 2;

[0020] The present utility model realizes the assembly cooperation between the cabinet 2 and the circuit breaker body 1 through the cooperation between the assembly part 10 and the assembly slot 22, and ensures the smooth insertion and extraction of the circuit breaker body 1.

[0021] The assembly part 10 is a strip-shaped structure adapted to the slot 22.

[0022] During use, the assembly part 10 adopts a strip-shaped structure to ensure its cooperation strength with the slot 22.

[0023] The middle of the assembly part 10 is disconnected to form a first insertion strip 11 and a second insertion strip 12.

[0024] During use, the middle of the assembly part 10 is disconnected, so that the friction coefficient during insertion and extraction is small, ensuring smooth insertion and extraction. The gap design of the middle disconnection can prevent plastic chips from getting stuck during insertion and reduce the air resistance during rapid insertion.

[0025] The insertion ends of the first insertion strip 11 and the second insertion strip 12 are both formed with tapered heads 13.

[0026] During use, when the circuit breaker body 1 is assembled with the cabinet 2, the tapered head 13 part enables the end of the insertion strip to enter the corresponding slot 22 more smoothly, avoiding plastic chips from being generated and getting stuck during insertion.

[0027] The length of the second insertion strip 12 is 2 / 3 of that of the first insertion strip 11.

[0028] During use, when the circuit breaker body 1 is initially inserted, positioning and guiding are realized through the cooperation between the first insertion strip 11 and the slot 22. When the circuit breaker body 1 reaches the preset installation position, the second insertion strip 12 enters the slot 22. The length of the second insertion strip 12 is 2 / 3 of that of the first insertion strip 11, ensuring the assembly stability of the circuit breaker body 1 and the cabinet 2 while saving materials.

[0029] Two slots 22 are formed at each circuit breaker assembly position of the cabinet 2, and two assembly parts 10 adapted to the slots 22 are formed on each circuit breaker.

[0030] During use, the assembly of each circuit breaker is realized through the cooperation between two assembly parts 10 and two slots 22, ensuring both assembly stability and smooth insertion and extraction.

[0031] The assembly part 10 is integrally injection-molded with the circuit breaker housing.

[0032] During use, the assembly part 10 is integrally formed with the circuit breaker housing to ensure the structural strength of the assembly part 10.

[0033] It should also be noted that the terms used in the present utility model, such as "front", "rear", "vertical", "horizontal", etc., refer to the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. This 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 should not be construed as a limitation on the protection scope of the present utility model.

[0034] The above is only the preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any technical solution falling within the concept of the present utility model belongs to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
