The first sealing ring 40 and the second sealing ring 41 are both made of silicone material and have excellent high temperature resistance.

[0049] Through the arrangement of the above structure, the first sealing ring 40 and the second sealing ring 41 can effectively prevent moisture and dust from entering the interior of the connector, thereby protecting the cable and its connecting parts, ensuring their normal operation and extending their service life.

[0050] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0051] When in use, when connecting the pin 5 with the core wire, the threaded rod 16 on the first protruding plate 8 is screwed out of the limiting plate 15, and then the block 17 is driven by the moving block 14 and the vertical plate 13 to move out of the card slot 18, so that the protrusion 10 can be separated from the first protruding plate 8, thereby separating the upper end seat 61 from the lower end seat 62, and then the core wire of the cable is arranged in a U-shaped bending according to the shape of the U-shaped groove 7, and at the same time, the pressing plate 22 is moved upward to drive the first spring 21 to stretch, and after one end of the core wire is wrapped around the bottom end of the vertical rod 20, the pressing plate 22 is released. Under the reaction force of the first spring 21, the pressing plate 22 can press and limit the core wire to improve the connection stability. After the core wire is arranged in the socket, the upper end seat 61 and the lower end seat 62 are assembled again through the locking assembly to complete the connection between the pin 5 and the core wire;

[0052] When the cable connector is disassembled, the protective tube 3 is rotated out of the threaded end of the shell 1, and the protective tube 3 can be separated from the shell 1. By screwing the hand nut 37 directly out of the screw rod 36, the first arc plate 33 and the second arc plate 34 can be separated, and the fixing block 38 is moved out of the shell 1, so that the shell 1 and the screw sleeve 2 are separated. Conversely, the first arc plate 33 and the second arc plate 34 are merged, and the fixing block 38 enters the fixing groove 39 of the shell 1. The hand nut 37 is tightened on the screw rod 36, and the shell 1 and the screw sleeve 2 can be installed. By pulling the extension plate 29, the stopper 28 and the limit block 25 are driven to move into the installation groove 26, the second spring 27 is squeezed, and the limit between the support frame 4 and the shell 1 is released, so that the pin 5 can be removed from the connector, and vice versa, it can be installed, the operation is quick, and the assembly is simple.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
