What environmental performance should a quality connector have?

The same object has different technical performance in different environments, so it is also an important index to evaluate the quality of an object and judge how many environmental conditions it can withstand. Connector is a familiar component in the field of electronic engineering, which is used in every corner of our production and life. In order to meet the application requirements of various complex and harsh environments, its environmental performance is particularly important. The working environment of the connector has a great influence on its performance. The main influencing factors are temperature, humidity, pH value, oscillation and impact, liquid immersion, etc. These factors will affect the service life of the connector.

① Temperature can change the physical state of the object, which is a factor that strongly affects the efficiency of the connector. Due to the different seasons, the ambient temperature will be very different. After connecting two components, the current will also generate heat when it passes through, which will increase the temperature. The sum of the two is the working temperature. The metal component in a good connector should be able to maintain its physical state at a certain temperature to ensure its high efficiency. Generally speaking, it can withstand a maximum temperature of 200 degrees and a minimum of 65 degrees below zero. ② The effect of moisture on the connector is actually the effect of moisture. Because water has a corrosive effect on metal parts, it also has a certain conductivity, which can reduce the insulation, so the component material of the connector must be the least affected by water. In general, the connector should be able to operate normally for at least 96 hours at a relative humidity of 90% -95% and a temperature of about 40 ℃. ③ Salt spray refers to the salt contained in water vapor, which will cause chemical corrosion to metal parts and affect the electrical performance of connectors. Generally speaking, it can work continuously for more than 48 hours in a salt spray environment artificially created with a specific sodium chloride solution. ④ Vibration and impact mainly affect the connection strength and electrical contact reliability of the connector. Generally, the vibration and impact environment shall be simulated according to the relevant parameters according to the use environment, and its performance shall be tested. ⑤ The effect of liquid immersion method is similar to that of water. Relative to humidity, the water content in the environment is large and the action time is short. Generally, the liquid immersion resistance is evaluated by testing the sealing performance. Due to the different application objects and application environments, the appearance and structure of the connector are also different. However, in any case, the connector must ensure the continuity and reliability of the current of the connected parts. In order to achieve this goal, the environmental characteristics of the connector must be analyzed in depth, and the appropriate connector must be used on the appropriate electronic device.
