How to use the USB connector

1. High-temperature environment: The metal and insulating materials of the USB connector determine the operating temperature of the connector. High temperature will damage the edge material, resulting in lower insulation resistance and voltage resistance. For metal, high temperature will make the contact vice lose elasticity, accelerate oxidation and deteriorate the coating. Usually the ambient temperature is -40 ~ 80, special occasions may be higher. 2. humid environment: relative humidity greater than 80%, is the main cause of electrical breakdown. Humid environment leads to the absorption and diffusion of water vapor on the insulator surface, which tends to reduce the insulation resistance to under the MQ level. Long-term exposure to high humidity can cause physical deformation, decomposition, and escape of the product, respiratory effects, electrolysis, corrosion, and cracking, especially in equipment. For external connectors, environmental conditions such as humidity, seepage and contamination often need to be considered. In this case, the USB connector should be sealed.3. Temperature change: Humidity change test is to simulate the actual use of the USB connector in a cold environment to a warm environment, or to simulate the ambient temperature of spacecraft and probes. Sudden changes in temperature may cause the insulation to crack or delaminate.4. Thin Air Environment: In high altitude areas with thin air, the plastic emits gases that contaminate the contact pairs, increasing the tendency for corona to be generated, decreasing the withstand voltage, and causing the circuit to experience a short-circuit failure. At high altitude when it reaches a certain value, the performance of plastic deterioration. Therefore, the use of non-sealed connectors at high altitudes, shall reduce its performance. 5. corrosive environment: according to the USB connector in different corrosive environments, the use of the corresponding metal, plastic, plating structure of the connector, such as salt spray environment using the connector.-6, on the Evergrande electronic products network platform related to the introduction and sales of products briefly: Evergrande electronic products network - a professional agent / production / sales of all kinds of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] procurement / purchasing needs or would like to buy / to understand which connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
