A lifting component is provided inside the mounting base 8, and the lifting component includes a tooth plate 14, a tooth column 15, a worm gear 16 and a worm 17. The tooth plate 14 is installed inside the mounting base 8, the tooth column 15 is meshedly connected to one side of the tooth plate 14, and the worm gear 16 is connected to the tooth plate 14 through a rotating shaft, and the worm gear 16 is meshed.
[0025] Specifically, the worm gear 16 is rotatably connected to the inner wall of the mounting seat 8 via a rotating shaft, thereby ensuring the stable rotation of the worm gear 16 inside the mounting seat 8, and when the worm 17 rotates, it can drive the worm gear 16 to rotate, and the worm gear 16 can drive the gear column 15 to rotate on the gear plate 14. When the gear column 15 rotates on the gear plate 14, it can drive the gear plate 14 to move inside the mounting seat 8, and due to the self-locking nature of the worm gear 16 and the worm 17, the worm gear 16 will not rotate under normal conditions, thereby preventing the gear column 15 from rotating, and thereby preventing the gear plate 14 from falling due to its own gravity.
[0026] Reference Figure 1 and Figure 3 A knob 11 is provided on one side of the mounting seat 8, and the knob 11 is connected to the worm 17. The top surface of the tooth plate 14 is fixedly connected to the lifting plate 9, and the sliding plate 7 is movably installed inside the lifting plate 9. The bottom surface of the sliding plate 7 is fixedly connected to the fixed plate 6, and the bottom surface of the fixed plate 6 is fixedly connected to the fixed block 5, and the fixed block 5 is fixedly connected to the baffle 2.
[0027] Specifically, the knob 11 is placed on the outside of the mounting base 8, so that the user can turn the knob 11 to drive the worm 17 to rotate. The lifting plate 9 is movably installed inside the mounting base 8, so that when the tooth plate 14 moves inside the mounting base 8, it can drive the lifting plate 9 to rise and fall. When the lifting plate 9 is raised and lowered, it can drive the sliding plate 7 to rise and fall. The sliding plate 7 drives the fixed plate 6 to rise and fall. The fixed plate 6 can drive the baffle 2 to rise and fall through the fixed block 5. When the electrical connector is in use, the baffle 2 can be raised to expose the terminal body 13. When the electrical connector is not in use, the baffle 2 can be lowered to seal the opening of the connector end 1, thereby protecting the terminal body 13.

When the electrical connector is used, the blocking cover 2 can be raised a certain distance and the sliding plate 7 can be slid. The sliding plate 7 drives the fixed block 5 to move toward the mounting seat 8 through the fixed plate 6. The fixed block 5 drives the blocking cover 2 to move, and the blocking cover 2 can be moved close to the mounting seat 8, so that the connector end 1 can be connected to the female end. The blocking cover 2 and the sliding plate 7 will not hinder the connection of the connector end 1. The size of the limit block 10 is larger than the size of the sliding groove 12, so as to prevent the sliding plate 7 from falling off the lifting plate 9, and when the limit block 10 contacts the lifting plate 9, the blocking cover 2 is located directly above the opening of the connector end 1. At this time, it is only necessary to control the blocking cover 2 to descend, so that the blocking cover 2 can block the opening of the connector end 1.

A plurality of tension springs 19 are provided inside the cover, and the two ends of the tension spring 19 are respectively connected to the rubber plate 18 and the inner wall of the barrier cover 2.
[0031] Specifically, one end of the pull rod 3 extends out of the outside of the block cover 2, so that the pull rod 3 can be pulled to drive the rubber plate 18 to move inside the block cover 2, thereby preventing the block cover 2 from being lowered and the position of the rubber plate 18 from getting stuck in the connector end 1 and affecting the lowering of the block cover 2. Through the reverse action force of the tension spring 19, the rubber plate 18 can be pushed to fully contact the surface of the connector end 1, thereby ensuring the sealing inside the connector end 1 and preventing foreign matter from entering the interior of the connector end 1 and affecting the connection and use of the electrical connector.
