Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

In the embodiments, as shown in FIGS. 1 to 6: a cable connector comprises an upper plug 100 and a lower plug 200 which are mutually inserted and matched, and a reinforcing member 300 for reinforcing the upper plug 100 and the lower plug 200, wherein the upper plug 100 is provided with an upper fixing column 101, the lower plug 200 is provided with a lower fixing column 201, the reinforcing member 300 is an integrated U-shaped structure formed by two side plates 301 and a connecting plate 302, the upper end of each side plate 301 is provided with a hook 303 corresponding to the upper fixing column 101, the lower end of each side plate 301 is hinged on the lower fixing column 201, the lower end of each side plate 301 is provided with a hinge hole 304 corresponding to the lower fixing column 201, the hinge hole 304 is provided with an assembly notch 305 extending to the edge of each plate, the assembly notch 305 is a flared opening with a small inside and a large outside, and the gap at the minimum opening of the. The hinge hole 304 of the reinforcing member 300 of the present embodiment utilizes the assembly notch 305 to complete the installation with the lower fixing column 201, no other auxiliary structure is needed, the reinforcing member 300 is a single part, the whole structure is simple, and the processing cost is low.

In the embodiment, as shown in fig. 5 and 6: one side of the fitting notch 305 is tangent to the hinge hole 304. In the structure of this embodiment, the assembly notch 305 and the hinge hole 304 have a cut edge, thereby facilitating the sliding of the lower fixing post 201.

In the embodiment, as shown in fig. 5 and 6: the fitting notch 305 is provided at a side of a line connecting the hinge hole 304 and the hook 303, and the hinge hole 304 and the fitting notch 305 form a hook shape together. In the structure of this embodiment, the hinge hole 304 and the assembly notch 305 form a hook-shaped tensile force, that is, the assembly notch 305 has substantially no bearing force, so that it can be ensured that the hook-shaped tensile force will not loosen when being pulled.
