Pogo pin spring thimble waterproof method!Solder-cup Pogo Pin Processor

　　The pogo pin spring thimble is waterproof, so how is it waterproof? The water resistance of the pogo pin spring thimble mainly depends on its performance. Let’s take a look at the reasons why the pogo pin spring thimble is waterproof. .

　　High temperature resistance performance:

　　The working temperature of pogo pin spring thimble is 200℃, and the low temperature is -65℃. When it is connected, the current generates heat at the contact point, causing temperature rise. It is generally considered that the operating temperature will be equal to the sum of the ambient temperature and the temperature rise of the contact. In some specifications, the allowable temperature rise of the connector in the rated operating current will be clearly specified.

　　Humidity resistance:

　　Moisture will affect its insulation and corrode metal parts. The constant heat and humidity test conditions are relative humidity 90%~95%, temperature +40±20℃, and the test time depends on the product regulations, at least 96 hours. The pogo pin spring thimble has a more stringent alternating damp and heat test.

　　Salt spray resistance:

　　When it is working in an environment containing moisture and salt, the surface treatment layer of its metal structure and contacts may have 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 environment, a salt spray test is specified. The connector is hung in a temperature-controlled test box, and a sodium chloride solution of a specified concentration is released with compressed air and turned into a salt spray atmosphere. The exposure time is according to the product specification, at least 48 hours.

　　Vibration and shock resistance:

　　Vibration and shock resistance of pogo pin spring thimble is an important performance of electrical connectors. It is especially important in special environments such as aviation and aerospace, railway and road transportation. It is to check the robustness of the electrical connector's mechanical structure and electrical contact reliability Important indicators. There are clear regulations in the relevant test methods. The shock test shall specify the peak acceleration, duration and shock pulse waveform, and the time of interruption of electrical continuity.
