The environment itself is the basis of testing an object, and it is an important index to test the quality of the object, because the technical performance of the object in use will change according to the different environment. The pin jack is often used in different environments. In order to ensure the stability of performance and meet the requirements of various complex and harsh environments, its environmental performance is very important. Temperature, humidity, salt spray, vibration and impact will affect the life of pin sockets.
Temperature: Temperature is a physical quantity indicating the degree of heat and cold of an object. Temperature varies in different seasons and regions. It can change the physical state of an object and has a great impact on the efficiency of pin jacks. In order to ensure the high efficiency of the connector, it is required that the internal metal components of the connector should keep the physical state unchanged within a certain temperature. Therefore, the temperature range required for the connector is - 60 degrees - 200 degrees. After connecting the two components, the current will generate heat and the temperature will rise. This is the working temperature. Generally speaking, the working temperature and the ambient temperature are in the range of 200 degrees, which is a tolerable temperature range.
Humidity: Humidity is a physical quantity indicating the degree of dryness in the atmosphere. Water is corrosive to metal components, and has certain conductivity, which can reduce insulation. At a certain temperature, in a certain volume of air, the higher humidity, the more water vapor in the air, which will affect the performance of connectors. Therefore, the material requirements of connectors must choose water which has the smallest impact, and the same rules. The connector must be able to work normally for at least 96 hours at a temperature of about 40 degrees and relative humidity of 90%-95%.
Salt fog: Salt fog refers to a dispersion system consisting of tiny salty droplets in the atmosphere. When the temperature is 35 C and the concentration of salt solution is 3%, it will cause great corrosion to the object, especially the components of metal materials, which will affect the performance of pin jacks. In order to avoid the influence of salt fog on its performance, it is required to work continuously for at least 48 hours in a salt fog environment manually manufactured from a specific sodium chloride solution.
Vibration and shock: often affect the electrical contact reliability and robustness of connectors. Usually in the production process, the performance of connectors is tested by simulating the environment of vibration and shock according to the relevant parameters to prolong the service life.
These are the different requirements of pin jacks in different environments introduced by Xiaobian. The environment is one of the factors affecting objects. The same is true of pin jacks. In order to ensure that it can better adapt to different environments, it is very important to adapt to the requirements of the environment.
