Embodiment approach
[0039] According to one embodiment of the present invention, the method for sealing the cable pipeline structure of the present invention includes:
[0040] S1. Connect the base 11 with the cable hole on the side wall A of the ventilation duct of the spacecraft, set the connecting pipe 2 on the body 12, and fasten the connecting pipe 2 with nylon cable ties 3 . In this embodiment, the base 11 is connected to the side wall A by screws, and the annular seal 111 is compressed by the base 11 .
[0041] S2. Tighten the connecting pipe 2 and the cables passing through the connecting pipe 2 with nylon cable ties 3 . In this embodiment, there are at least two nylon cable ties 3 at the fastening position between the connecting pipe 2 and the cable. By fastening the connecting pipe 2 and the cable B, the gap between the connecting pipe 2 and the cable B becomes smaller, thereby further ensuring the tightness of the connecting pipe 2 and the cable B, and enhancing the cable pipeline str...
