Pogo pin heads have relatively high temperature resistance. At present, the highest working temperature of pogo pin connectors is 200 degrees Celsius, and the lowest is -65 degrees Celsius. As the connector is working, the current will generate heat at the contact point, resulting in an increase in temperature, so it is generally felt that the working temperature is equal to the sum of the ambient temperature and the temperature of the contact point. Some specifications clearly specify the maximum allowable temperature of the connector under the rated operating current.
Moisture of the plug has a great influence on the insulation of the connector and will corrode metal parts. The test conditions of room temperature damp heat are: relative humidity 90%~95%, temperature +40±20℃, and the test time cannot exceed 96 hours. The alternate damp heat test is more stringent.
When the connector is working in a damp and salty environment, the surface treatment layer of its metal structural parts and contacts will appear galvanic corrosion, which has a great impact on the physical and electrical properties of the connector. The salt spray test is used to evaluate the resistance of electrical connectors in this environment. Hang the connector in a controlled temperature test box, and spray a sodium chloride solution with a specified concentration with compressed air to become a salt spray environment. According to the product specification, the contact time is at least 48 hours.
Vibration resistance and impact performance of electrical connectors are its important performance indicators, especially in special applications such as aerospace, railway and road transportation, and are important indicators for testing electrical connector mechanical structure robustness and electrical contact reliability. There are clear regulations in the relevant test methods. The shock wave test shall specify the peak acceleration, duration, and shock waveform as well as the power-off time.
