How is the pogo pin waterproof and what are its performance features?

　　With the development of electronic devices, many smart devices have introduced waterproofing as a major purchasing point, and high-quality thimbles, as connectors in smart devices, have waterproof functions. So how does its waterproof function be achieved? In fact, the waterproofing of high-quality spring thimbles mainly relies on their powerful performance. Now let's understand why high-quality thimbles are waterproof:

　　Firstly, the high-temperature resistance of high-quality pogo pin thimbles:

　　At present, the working temperature height of high-quality spring thimbles is 200 ℃, and the low temperature is -65 ℃. Due to the heat generated by the current at the contact point during connection operation, resulting in a temperature rise, it is generally believed that the working temperature should be equal to the sum of the ambient temperature and the contact temperature rise. In certain specifications, the allowable temperature rise of connectors under rated operating current is clearly specified.

　　Secondly, the moisture resistance of high-quality pogo pin thimbles:

　　The invasion of moisture can affect the insulation performance of connectors and corrode metal parts. The constant damp heat test conditions are relative humidity of 90%~95%, temperature of+40 ± 20 ℃, and the test time is specified by the product, with a minimum of 96 hours. The alternating damp heat test of high-quality spring thimbles is more stringent.

　　Thirdly, the salt spray resistance of high-quality pogo pin thimbles:

　　When high-quality spring thimbles work in environments containing moisture and salt, the surface treatment layer of metal structural components and contact parts may produce electrochemical corrosion, which affects the physical and electrical performance of the connector. In order to evaluate the ability of electrical connectors to withstand this environment, a salt spray test is specified. It suspends the connector in a temperature controlled test chamber and sprays out a specified concentration of sodium chloride solution with compressed air to form a salt mist atmosphere. The exposure time is specified by the product specifications and is at least 48 hours.

　　Fourthly, the vibration and impact resistance of high-quality pogo pin thimbles:

　　The vibration and impact resistance of high-quality thimbles is an important performance of electrical connectors, especially in special application environments such as aviation and aerospace, railway and road transportation. It is an important indicator for testing the robustness of the mechanical structure and electrical contact reliability of electrical connectors. There are clear provisions in the relevant test methods. The peak acceleration, duration, and pulse waveform of the impact test should be specified, as well as the time for electrical continuity interruption.
