Which environment will affect the performance of the terminal wire harness, no matter in that industry, there will be some special products, and some testing of product parameters, so that the product can not be affected in different environments.
1. Corrosive environment, mainly refers to products working around gas, such as marine salt spray, chemical material storage warehouses have acid and alkali, these conditions will cause corrosion and corrosion of metal parts such as terminal wires, insulators, etc., so you can Or choose products that meet these requirements to make specific requirements. It should also be noted that each connecting part is made of plastic and is not resistant to solvents such as benzene and acetone. The regulations in the product samples must be clarified.
2. Ambient temperature, the working environment of the terminal wire harnesses product should be used within the ambient temperature specified by the product. Even if the external environment temperature is not high, if the product is working on the shell, the temperature difference plus other heating elements will cause the product's ambient temperature to be much higher than the external environment temperature. Exceeding the specified ambient temperature will cause damage to the metal coating or insulators. Too low temperature will also cause the insulators to crack, which will eventually reduce the performance or failure of the terminal wire.
3. Humid environment. The humid environment will form a water film on the surface of the insulator of the terminal wire harness, reduce the insulation performance, and even cause misleading between adjacent contact parts. Generally, air plugs that are used for a long time under high humidity or water conditions should seal.
4. Mechanical environment, mainly refers to mechanical effects such as vibration, impact, collision and acceleration, and is selected according to the parameters of the terminal wire harness product sample. Generally speaking, similar products have higher twisting pins in the mechanical parameters, and it is easy to ensure that after paying attention to the actual use of the cable contact part, the cable clamp or other methods should be used to fix the cable that is too long and has no fixing measures. Vibration or impact will endanger the safety of the cable, and in severe cases, it will cause damage to the terminal line and cable damage.
5. In low-pressure environment, the pressure drop is low under high-altitude conditions. When the terminal wire harness products are under low-pressure conditions, the product quality pressure will decrease. If the transmission voltage is higher than the specified product technical conditions, electrical failure may occur.
