What affects the service life of circular connectors?

Circular connector service life is affected by what? The actual use of circular connectors in a very complex environment, although the product itself has a high degree of safety and reliability, can be adapted to many different environments. However, if used for a long time in harsh environments, the impact of the environment on its service life should not be ignored. Among the many environmental factors, humidity, temperature and salt spray are important factors affecting its service life. Why do you say so?1. Humidity. When the relative humidity in the environment is relatively high, the metal parts on the connector will be corroded, resulting in a new decline in the insulating properties of the circular connector, but the conductive properties have increased. As a result, if the connector is used in an area where there is constant rain or water, its service life will be shortened.

2. Temperature. Temperature will also affect the service life of the connector. We know that the temperature is different in different seasons, especially the cold winter and hot summer, the ambient temperature will be very high or very low, especially in hot weather. When the connector is connected to the power supply, the current itself will have a certain amount of heat. Coupled with high temperatures, this can easily cause the connector's jack temperature to rise, which can easily cause the connector to burn out. Generally speaking, the operating temperature of the connector is -60 -200. 3. Salt spray. According to research, when the ambient temperature is 35 and the concentration of salt solution in the environment is 3%, it is easy to cause metal corrosion. Therefore, when the circular connector is used in this environment, its performance decreases and its service life is shortened. In addition, vibration and shock will also affect the service life of the connector. If there is significant vibration and shock in the use environment, it will affect the firmness of the connection. Therefore, general manufacturers of products need to carry out vibration and shock tests before leaving the factory. How to extend the service life of circular connectors? First, control the heat of the connector Heat is the number one enemy of circular connectors and a common cause of connector failure. A lot of thermal damage is caused by improper cooling, which greatly reduces the reliability of some components. So when in use, always pay attention to the operating temperature. Second, to properly evaluate the connection system. To limit the impact of heat on the service life of the connector, the first step is to evaluate whether the design of the device connection system is reasonable. In accordance with tradition, it is necessary to determine which components can withstand the temperature range, so as to determine the choice of open-loop or closed-loop cooling system to reduce the early failure of circular connectors. Third, the use of open-loop cooling system if the use of open-loop cooling system, you need to rely on the air around the connector to dissipate heat. Simply put, we can install fans, motorized impellers or blowers near the connector to increase air mobility, thus helping the connector dissipate heat. However, if the ambient temperature itself is relatively high, the cooling effect of this approach is not obvious. Fourth, the use of closed-loop cooling system closed-loop cooling system can not only effectively reduce the temperature of the connector working part, and is not affected by the air environment. Generally, an air heat exchanger is used. When we store circular connectors, the correct storage can also avoid its premature failure, the storage warehouse should be ventilated and dry.
