[0020] The technical solution of the present invention will be clearly and completely described below through specific implementation methods.

[0021] refer to Figure 1-Figure 5 , is a semiconductor electric control cabinet cable entry sealing device of the utility model, including a cable entry plate 1; the cable entry plate is installed at the cable entry port of the semiconductor electric control cabinet; the cable entry plate 1 is provided with a plurality of entry holes 11; the first sealing member 12 and the second sealing member 13 are respectively provided on both sides of the entry hole 11.

[0022] The first sealing component and the second sealing component of the utility model are arranged on both sides of the wire inlet hole to ensure the sealing effect.

[0023] In this embodiment, a frame 15 and a frame 2 16 are respectively provided on both sides of the cable entry plate 1; the first sealing member 12 is installed in the frame 1 15; and the second sealing member 13 is installed in the frame 2 16.

[0024] The first sealing member 12 of this embodiment includes a corrugated sealing ring 121; one end of the corrugated sealing ring 121 is fixed on the cable entry plate 1, and the other end is fixed on the movable pressure plate 122; a bolt 123 is fixedly provided on the cable entry plate 1; a nut seat 124 threadedly connected to the bolt is provided on the movable pressure plate 122; the nut seat is rotatably connected to the movable pressure plate 122.

[0025] The corrugated sealing ring 121 of this embodiment includes a bottom ring body 001, a middle ring body 002, and a top ring body 003; the bottom ring body 001 and the top ring body 003 are respectively installed on the cable entry plate 1 and the movable pressure plate 122; the bottom ring body 001 and the middle ring body 002, as well as the middle ring body 002 and the top ring body 003 are connected by a flexible column 004; the side wall of the flexible column is a concave arc structure.
