[0049] The fixing plate 6 is fixedly installed on the outside of the plug 2. Two symmetrically arranged positioning rods 7 are fixedly installed on the left side of the fixing plate 6. Two symmetrically arranged positioning holes 8 are opened on the right end face of the connector 3, and the positioning holes 8 match the positioning rods 7.

[0050] The left side of the fixing plate 6 is fixedly installed on the rubber sealing gasket 9, and the rubber sealing gasket 9 is sleeved on the outside of the plug 2, and the length and width of the rubber sealing gasket 9 are larger than the inner length and inner width of the connector 3, respectively.

[0051] The rubber sealing block 10 is fixedly fitted on the outside of the plug 2, and the rubber sealing block 10 is located on the left side of the rubber sealing gasket 9. The mounting plate 11 is fixedly installed on the inner wall of the connector 3, and the interior of the mounting plate 11 is hollow. The rectangular block 12 is fixedly installed on the right side of the mounting plate 11, and the outer side of the rectangular block 12 is a slope with the left side higher than the right side. The rectangular groove 13 is opened on the left side of the rubber sealing block 10, and the outer length and width of the rectangular groove 13 are smaller than the outer length and width of the rectangular block 12, respectively.

[0052] The cavity 14 is located inside the right side of the positioning rod 7. The left and right end faces of the slide plate 15 are slidably connected to the left and right walls of the cavity 14, respectively.
