[0006] Furthermore, a binding positioning portion for positioning the binding structure is provided on the outer wall of the tail card body.

[0007] Furthermore, the binding structure is a cable tie, and the binding positioning portion is a socket through which the cable tie can be adapted to pass.

[0008] Furthermore, the binding positioning portion is composed of two insertion holes which are arranged radially opposite to each other on the outer wall of the tail card body.

[0009] Furthermore, a binding positioning portion is respectively provided at the front and rear ends of the tail card body.

[0010] Furthermore, the cable perforation is divided by the dividing groove to form a non-closed perforation structure.

[0011] Furthermore, it also includes a terminal protection cover, which is integrally formed at the front end of the tail card body.

[0012] Based on the same inventive concept, the utility model also provides a circuit breaker, comprising a circuit breaker body and any of the cable tail clamp structures described above, wherein the terminal protection cover comprises a side plate abutting against the side edge of the terminal of the circuit breaker body and a top plate connected to the top of the side plate to cover the top opening of the terminal.

[0013] Furthermore, a buckle head is formed on the top plate for buckling and fixing with the outer frame of the terminal.

[0014] Furthermore, a plurality of heat dissipation holes are provided on the top plate.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] In the cable tail card structure and circuit breaker described in the utility model, a dividing groove is opened on the peripheral wall of the tail card body along the axial direction of the cable perforation, and the closed structure of the cable perforation is cut by the dividing groove, so that the cable perforation forms a non-closed through-hole structure with a cross section similar to a C-shape. When in use, the tail card body can be opened to both sides along the dividing groove, thereby changing the threading hole size of the cable perforation. In this way, the cable tail card can adapt to cables with more wire diameters. After the cable passes through the cable perforation of the tail card body, the tail card body and the cable are tied and fixed by the binding structure, so that the cable and the tail card body are tightly connected together. Therefore, the cable tail card structure has good universal adaptability and can adapt to cables with various wire diameters. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Please refer to the attached Figure 1 To Attachment Figure 3 An embodiment of the utility model provides a cable tail card structure, including a tail card body 1, a cable through hole 11 penetrating through the front and rear ends of the tail card body 1 is opened in the tail card body 1, a dividing groove 12 opened along the axial direction of the cable through hole 11 is opened on the peripheral wall of the tail card body 1, and the tail card body 1 is configured to be fastened and connected with the cable passing through the cable through hole 11 through a binding structure. It can be understood that in this embodiment, a dividing groove 12 is opened on the peripheral wall of the tail card body 1 along the axial direction of the cable through hole 11, and the closing structure of the cable through hole 11 is cut by the dividing groove 12, so that the cable through hole 11 forms a non-closed through hole structure with a cross section similar to the letter C. When in use, the tail card body 1 can be opened to both sides along the dividing groove 12, thereby changing the threading hole size of the cable through hole 11, so that the cable tail card can adapt to cables with more wire diameters. After the cable passes through the cable through hole 11 of the tail card body 1, the tail card body 1 is tied and fixed with the cable by the binding structure, so that the cable and the tail card body 1 are tightly connected together. Therefore, the cable tail card structure has good universal adaptability and can adapt to cables of various wire diameters. The disconnection effect of the dividing groove 12 on the tail card body 1 makes the assembly process with the cable more convenient and efficient.
