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 waterproof treatment method for the cable network on the launch vehicle arrow includes the waterproof treatment of the welded electrical connector. The treatment is realized in the following way: Pretreatment of the welded electrical connector: first, the welding surface of the non-sealed welded electrical connection machine is Sealing treatment, and then apply glue to the welding surface and wire (7) of all welding-type electrical connectors, to increase the bonding force between the perfusion colloid and the perfusion surface; from the welding-type electrical connector tail cover (3) Inject the RTV107 silicone rubber (1) into the outlet (4) or the filling hole (15), the potting height should exceed the height of the solder cup (19) by 5mm, and stand vertically at room temperature for at least 24 hours to cure; for welding type electrical connector tail cover (3) Carry out external protection to realize 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...
