Because the socket 10 is provided with at least one shell limiting hole 110 on the shell and at least one base limiting hole 310 on the insulating base 300, so that one end of the bolt fixing piece 400 is respectively penetrated through each shell limiting hole 110 and each base limiting hole 310, and the other end of the bolt fixing piece 400 is abutted against one side of the insulating cladding piece 500, the retaining fixing of the insulating base 300 and the insulating cladding piece 500 is realized, and meanwhile, the retaining fixing structure of the insulating base 300 and the insulating cladding piece 500 is simpler, and the overall structure of the socket 10 is simplified;

3. Because each of the bolt fixing members 400 is inserted into each of the housing limiting holes 110 and each of the base limiting holes 310 to achieve the retaining fixing of the insulating base 300 and the insulating cover 500, in design, the number of the housing limiting holes 110 and the base limiting holes 310 is adjusted according to different sizes of the socket 10, so that the bolt fixing members 400 can adapt to the retaining assembly requirements of the socket 10 with different types, the universality of the bolt fixing members 400 is improved, the development cost of a die for producing the bolt fixing members 400 is reduced, and the manufacturing cost of the connector is reduced.

The foregoing examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
