USB connectors are easy-to-use machines and devices needed to connect various electronic products. At the same time, it does not occupy the parallel port and serial port communication of electronic products. Just connect the device to use, convenient and easy to use. USB connectors are often used for statistical transfers. Do you know how the USB connector operates in different environments? Do you have to pay special attention? The following is the explanation of Taiwei electronic equipment:
1. High temperature environment.
Huge temperature will destroy the raw material of the insulating layer, reduce the grounding resistance and compressive performance; high temperature will also make the metal material lose the ductility of contact, accelerate air oxidation, and cause changes in coating quality. In special cases, the normal ambient temperature may be -40~80℃.
2. In a humid and cold environment.
Air humidity over 80% is the main reason for electroosmosis. Vapors from wet and cold environments digest, absorb, and diffuse across insulating surfaces, reducing ground resistance. Physical deformation, dissolution and escape reactions can also result if often exposed to relatively high humidity and cold conditions, leading to breathing effects and electrolysis, erosion and cracking. In particular, USB connectors outside of mechanical equipment should be sealed in wet and cold environments.
3. In the environment of sudden temperature change.
When the ambient temperature changes drastically, the USB connector may cause cracks or cracks in the insulating material.
4. The environment with thin gas.
In the plateau climate environment, the exposure of plastics to the vapors of environmental pollution will lead to corona discharge, reduced pressure resistance, short-circuit failure of power circuits, and reduced plastic properties. Therefore, in this case, the amount must be adjusted when using unsealed connectors.
5. Erosion of the environment.
In corrosive environments, USB connectors should be constructed of corresponding metal materials, plastics and coatings. Without a corrosion-resistant metal surface, it can also lead to a rapid degradation of properties.
