[0066] Working principle:

[0067] When the protective cover 301 needs to be opened to connect the control line to the terminal block 2, the blocking strip 306 on one side can be pulled to move the movable plug rod 305 and stretch the limiting spring 308. The continuously moving movable plug rod 305 will slide in the L-shaped plate 304, and at the same time, it will slide out of the two fixed holes 307 in the movable sleeve ring 3 and the positioning plate 302, thereby releasing the connection restriction between the positioning plate 302 and the movable sleeve ring 3. At this time, the auxiliary spring 506 in the compressed state will push the sliding seat 505 to rise, and the rising sliding seat 505 will slide on the fixed guide rod 503 and push the protective cover 301 to rise, so that the protective cover 301 drives one of the rubber sealing rings 4 to rise, thereby pushing the protective cover 301 away from the terminal block 2, so as to take down the protective cover 301, and at the same time, the wiring position of the terminal block 2 is exposed. After the connection line is connected, one end of the connection line can be passed through the wire hole 401 and located in the limiting clamp two 501, and then the protective cover 301 is covered again, so that the protective cover 301 wraps around the connection position of the terminal block 2 and the connection line. Then press the protective cover 301 downward, the protective cover 301 will press on the movable sleeve ring 3 and drive it downward, so that the two rubber sealing rings 4 contact each other, block the connection position, and the wire hole 401 is attached to the surface of the connection line to prevent dust or water from entering the connection position of the connection line. At the same time, the descending movable sleeve ring 3 will drive the sliding seat 505 to compress the auxiliary spring 506 again, so that the auxiliary spring 506 is compressed, and the protective cover 301 can drive the positioning plate 302 to reinsert into the positioning hole 303, so as to avoid the position of the protective cover 301 from being deviated. When the positioning plate 302 and the fixed hole 307 on the movable sleeve ring 3 are aligned, the blocking strip 306 can be released. At this time, the stretched limiting spring 308 will retract and pull the blocking strip 306 back to its original position, so that the blocking strip 306 drives the movable plug rod 305 to reinsert into the fixed hole 307, thereby fixing the position of the protective cover 301, and the installation operation of the protective cover 301 is completed.

[0068] When the protective cover 301 is lowered, the limiting clamp one 5 and the limiting clamp two 501 can be pressed on the surface of the connection line. After the position of the protective cover 301 is fixed, the sliding seat 505 and the movable sleeve ring 3 can be always pressed upward under the action of the auxiliary spring 506, so that the limiting clamp two 501 clamps the connection line. At this time, the hot melt adhesive can be injected into the cavity 507 in the limiting clamp one 5 and the limiting clamp two 501 through the injection pipe 508. After the hot melt adhesive solidifies, the position of the connection line in the limiting clamp one 5 and the limiting clamp two 501 can be fixed, thereby avoiding the connection line from falling off from the connection position when it is pulled.

[0069] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
