Two important basic requirements for customized aerospace connectors!

Heat, impact, vibration and radiation are all key environmental considerations in aerospace connector systems, so customized aerospace connectors must be strong enough to withstand the requirements of harsh environments, such as impact and exposure to temperature cycles, as well as foreign substances such as dust, water and chemicals, this article Huichengyuan connector manufacturers mainly share with you two important basic requirements for customized aerospace connectors!

-------------------------------------------------------------------------------------------------

When space equipment leaves the Earth's surface, the spacecraft is bombarded with radiation levels, and the farther it flies, the higher the radiation levels will be. It will also have to withstand greater temperature extremes, potential collisions with all kinds of space junk, and the possibility that Earthlings will not be able to repair it, all of which make durability and reliability key features of custom space connectors. In addition to these requirements, newer small satellite designs, such as the compact CubeSat, require miniaturized, high-density components, which include connectors. General connector requirements for aerospace electronics closer to Earth, such as launchers, are somewhat similar to onboard electronics in deep space satellites, with the main difference being the materials used in deep space. Due to the high level of quality control, it is necessary to make connectors and cables the same regardless of the application. What changes is the testing required by specific markets. The two most important basic requirements for customizing electronics and connectors for aircraft are the ability to operate successfully in a vacuum and withstand radiation effects, because the outgassing of some plastics in a vacuum can deposit materials on the electronics, which will degrade their performance over time. The effects of radiation on spacecraft and its components are also related to plastics, and the connectors use polyphenylene sulfide [PPS] as insulation, which resists these effects and has very low levels of outgassing. To combat radiation, cables and connectors on spacecraft typically require stainless steel housings and polyetheretherketone (PEEK) insulators instead of liquid crystal polymers (LCPs), which is called radiation hardening or radiation hardening. But if the connectors are located within a radiation-resistant package, they do not always have to be radiation-resistant. Furthermore, certain metals such as pure tin, cadmium, and zinc, are banned from space due to their mechanical reactions, and any non-metallic materials, such as plastics, are at risk of being damaged by radiation exposure. Therefore, the dielectric materials in customized aerospace connectors or cables must be radiation-resistant and gas-removing.
