What Should I Pay Attention To When Using Rectangular Connectors?

Connector Insert Operating temperature: refers to the operating temperature required by the finished product. Even if the external operating temperature is not high, if the product is working in the main chassis, the heat dissipation of the heat pipe is poor and the heating of other electronic components will cause the operating temperature of the product to be higher than the external operating temperature. Using the operating temperature exceeding the required temperature may also damage the metal coating or conductors and insulators. Humidity or water: Humidity or water will cause shrinkage on the surface of conductors and insulators, which will reduce the dielectric strength and even cause adjacent contacts. Generally, connectors that are used in high humidity or water conditions for a long time should use connectors with sealing functions. Low pressure: The standard pressure will decrease under high conditions (except for the sealed chamber with stable standard pressure). When the product is under low pressure conditions, the material withstand voltage test of the product will be reduced. If the transmitted voltage exceeds the requirements of the product technical standards, there is always a possibility of electrothermal breakdown, resulting in failure. Corrosive environment: refers to the atmosphere around the product when it is working, such as corrosion in water, strong acids and alkalis in chemical raw material storage warehouses, etc. These conditions will cause corrosion and deposition on the metal products, conductors and insulators of the connector. When using the connector, you should ask the manufacturer for it or choose products that can meet these requirements.
