Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0039] The waterproof treatment method of the cable net on the carrier rocket arrow of the present invention mainly includes the waterproof treatment of the welded electrical connector (such as figure 1 , figure 2 shown), waterproof treatment of wire contacts in the wiring harness (such as image 3 , Figure 4 shown), crimping type electrical connector waterproof treatment (such as Figure 5 shown) in three aspects. Of course, according to different engineering practices, any one or more aspects of the above-mentioned waterproof treatment can be carried out.

[0040] The above three aspects will be described in detail below in combination with examples.

[0041] 1. Waterproof treatment of welded electrical connectors

[0042] 1.1 Electrical connector pretreatment

[0043] Follow the steps below to require waterproof pretreatment for soldered elec...

Abstract

The present invention provides a carrier rocket on-rocket cable system water-proof processing method comprising welding electrical connector water-proof processing, and the processing is implemented through a mode mentioned below: performing preprocessing of a welding electrical connector: a non-sealed welding electrical connector is subjected to welding surface sealing processing, all the weldingsurfaces and wires (7) of the welding electrical connector are subjected to coating processing to add the bonding force between a perfusion colloid and a perfusion surface, RTV107 silicone rubber (1)is injected from an outgoing line port (4) or a perfusion hole (15) of the tail cover (3) of the welding electrical connector, wherein the encapsulation height should be larger 5mm than the height ofa welding cup (19), the vertical standing and solidification are performed for at least 24 hours in a room temperature, and the tail cover (3) of the welding electrical connector is subjected to outer protection to achieve the sealing of the tail cover.

Description

technical field [0001] The invention relates to a waterproof treatment method for a cable net on a carrier rocket, in particular to a waterproof treatment method for a welded electrical connector, a press-fit electrical connector, and a wire contact point in a wiring harness. Background technique [0002] With the construction of my country's future space station and Beidou navigation system, the third phase of the lunar exploration project and the implementation of other deep space exploration programs, the space launch tasks are becoming increasingly heavy. The newly built Hainan Wenchang Satellite Launch Center has also become the fourth largest space launch center in my country after Jiuquan, Xichang and Taiyuan. Compared with other launch centers, Wenchang Satellite Launch Center has the characteristics of low latitude, convenient shipping, and adjacent to vast sea areas. It is an ideal launch site for new-generation launch vehicles and new spacecraft. Since Wenchang L...
