[0021] like Figure 2 , Figure 3 and Figure 4 As shown, one end of connector No. 1 is fixedly connected to a connecting seat 6, one end of connector No. 1 is fixedly connected to a separating ring 8 located inside the connecting seat 6, a connecting cap 7 is rotatably connected to the outer surface of connector No. 2 and close to one end, the inner surface of the connecting cap 7 is threadedly connected to the outer surface of the connecting seat 6, one end of connector No. 2 is fixedly connected to a sealing ring 9, the sealing ring 9 is plugged into a gap formed between the connecting seat 6 and the separating ring 8, and the connecting cap 7 and the connecting seat 6 are provided to connect connector No. 1 and connector No. 2, and to seal the connection of the wiring harness 16, and the sealing ring 9 can be provided to seal the connection.

[0022] like Figure 3 As shown, a sealing gasket 10 is placed between the connecting seat 6 and the separating ring 8, and one end of the sealing gasket 10 is in close contact with one end of the sealing ring 9. By providing the sealing gasket 10, the sealing effect can be improved.

[0023] like Figure 1-4 As shown, sealing sleeves 11 are inserted into the two adjusting caps 4, and multiple rubber rings 12 are fixedly connected to the outer and inner surfaces of the two sealing sleeves 11. By inserting the sealing sleeves 11 into the adjusting caps 4, the rubber rings 12 on the outer surfaces are deformed and in close contact with the inside of the adjusting caps 4, thereby improving the sealing effect. Multiple rubber rings 12 can perform multi-stage sealing to further improve the sealing effect.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the two sealing sleeves 11 are both plugged with wiring harnesses 16 , and one end of the two wiring harnesses 16 passes through the two outlet holes 5 respectively, so that the wiring harnesses 16 can be connected between the No. 1 connector 1 and the No. 2 connector 2 .
