[0026] In this embodiment, when wiring on site, the claw 5 is first installed into the screw cover 4. After the sealing ring 3 and the sealing ring 6 are installed in place, one side of the cable is inserted into the claw 5, and passes through the sealing ring 6 and the shell 2 in sequence, and finally welded and installed on the flange connector 1. After that, by tightening the shell 2, the shell 2 is installed on the flange connector 1, and the sealing ring 5 is squeezed, thereby achieving waterproof and dustproof protection at the connection between the shell 2 and the flange connector 1. Finally, the screw cover 4 is tightened and installed on the shell 4, so that the screw cover 4 squeezes the claw 5 during the installation process, and the claw 5 applies an extrusion force to the cable, so that the claw 5 can firmly lock the cable to prevent the welding point from loosening when the cable is pulled and dragged. After the screw cover 4 is installed in place, the screw cover 4 has an extrusion effect on the sealing ring 6, which can achieve a sealing, waterproof and dustproof effect between the shell 2 and the screw cover 4.

[0027] Example 2, as Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: the flange connector 1 includes a connection base 7, the surface of which is provided with two groups of twisting blocks 8, one group of twisting blocks 8 being arranged in a hexagonal structure, and the other group of twisting blocks 8 being arranged in an octagonal structure.
