What kind of environmental performance should a good connector have?

The same object has different technical properties in different environments. Therefore, it is also an important indicator to evaluate the quality of an object and how much environmental conditions it can withstand. For the connector, a familiar part of the field of electrical engineering, it has been applied to all corners of our production and life. To meet the needs of a variety of complex and harsh environments, its environmental performance is particularly important.

We know that the environment of the connector has a great impact on performance. The main influencing factors are temperature, humidity, acid and alkali, vibration and impact, and liquid impregnation. These factors also affect the working and life of the connector. The impact of these factors on connector performance.

Temperature can change the physical state of the object. It is a very strong factor affecting the performance of the connector. Due to different seasons and geographical differences, the ambient temperature will be much different. When the connector is connected to two components, the heat will also be generated when the current passes. This causes the temperature to rise, and the sum of the two is the operating temperature. A metal component in a good connector should be able to maintain its physical state at a certain temperature to ensure its high performance. It is usually stipulated that it should withstand a maximum of 200 degrees and a minimum of minus 65 degrees. The effect of humidity on the connector is actually the effect of water. Because water is corrosive to metal components, it also has a certain conductivity, which can reduce the insulation. Therefore, the component materials of the connector must have the least influence on water. It is usually stipulated that the connector should be able to operate at least 96 hours at a relative humidity of 90%-95% and a temperature of about 40 degrees. Salt spray is the salt contained in moisture, which can cause chemical corrosion to metal components and affect the electrical properties of the connector. It is generally stated that it is capable of operating for at least 48 hours in a salt spray environment artificially prepared with a specific sodium chloride solution. Vibration and shock mainly affect the robustness of the connector and the reliability of the electrical contact. It is usually tested according to the environment in which the connector is applied, and the vibration shock environment is simulated according to the relevant parameters. The effect of liquid impregnation is similar to that of water. Compared with humidity, it shows a large surrounding water and a short duration of action. The ability to resist liquid impregnation is usually evaluated by examining the tightness.

Because of different application objects and different application environments, the shape and structure of the connectors are not the same. However, the connector must be able to maintain the current continuity and reliability of the connected components. To achieve this, it is necessary to delve into the environmental performance of the connector and apply the appropriate connector to the appropriate electronic device.
