Pogo pin waterproof needs to do the following!Solder-cup Pogo Pin Production

　　The rapid development of electronic equipment, many smart devices have introduced the purchase point of waterproof, and high-quality pogo pins are connectors in smart devices, which have waterproof function, and the waterproof performance of high-quality pogo pins mainly depends on its powerful performance. Understand the reasons why high-quality pogo pins are waterproof.

　　1. High temperature resistance of high-quality pogo pins:

　　The current working temperature of high-quality pogo pins is 200℃, and the low temperature is -65℃. Because the current will have heat at the contact point during connection work, causing temperature rise, it is generally considered that the working temperature will be equal to the sum of the ambient temperature and the temperature rise of the contact point. In some regulations, the allowable temperature rise of the connector under the rated operating current is clearly specified.

　　2. Humidity resistance of high-quality pogo pins:

　　Moisture intrusion has an impact on the insulation performance of the connector, and it will corrode metal parts. The constant heat and humidity test conditions are relative humidity 90%~95%, temperature +40±20℃, and the test time is based on product regulations, and the minimum is 96 hours. The high-quality pogo pin alternating damp heat test will be more stringent.

　　3. Salt spray resistance of high-quality pogo pins:

　　When a high-quality pogo pin is working in an environment with moisture and salt content, its metal structure and contact surface treatment layer may undergo galvanic corrosion, which will affect the physical and electrical properties of the connector. In order to evaluate the ability of electrical connectors to withstand this type of environment, a salt spray test is specified, that is, the connector is suspended in a temperature-controlled test box, and compressed air is sprayed with a sodium chloride solution of a specified concentration to form a salt spray atmosphere , Its exposure time is determined by product specifications, at least 48 hours.

　　4. Vibration and shock resistance of high-quality pogo pins:

　　Vibration and shock resistance of high-quality pogo pins is an important performance of electrical connectors. It is particularly important in special use environments such as aviation and aerospace, railway and road transportation. It is to test the robustness and electrical contact of electrical connectors. An important indicator of reliability. It will be clearly specified in the relevant test methods. In the shock test, there are specified peak acceleration, duration and shock pulse waveform and electrical continuity interruption time.
