  With the development of electronic devices, many smart devices have introduced waterproofing as a major buying point, and high-quality spring thimble is used as a connector in smart devices. It is waterproof, so how does its waterproof function do it? What? In fact, the waterproof of high-quality pogo pins mainly depends on its strong performance. Let's take a look at the reasons why high-quality pogo pins are waterproof.

  First, the high temperature resistance of high-quality pogo pin spring thimble:

  The current working temperature of high-quality spring thimble is 200℃, and the low temperature is -65℃. Since the current generates heat at the contact point during connection work, which leads to a temperature rise, it is generally believed that the working temperature should be equal to the sum of the ambient temperature and the temperature rise of the contact point. In some specifications, the allowable temperature rise of the connector under the rated operating current is clearly specified.

  Second, the humidity resistance of high-quality pogo pin spring thimble:

  The intrusion of moisture will affect the insulation performance of the connector and corrode metal parts. The constant heat and humidity test conditions are relative humidity 90%~95%, temperature +40±20℃, and the test time is as specified by the product, at least 96 hours. High-quality spring thimble alternating damp heat test is more stringent.

  Third, the salt spray resistance of high-quality pogo pin spring thimble:

  When the high-quality spring thimble is working in an environment containing moisture and salt, the surface treatment layer of its metal structure and contact may produce 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. It hangs the connector in a temperature-controlled test box and sprays out a sodium chloride solution with a specified concentration with compressed air to form a salt spray atmosphere. The exposure time is specified by the product specification, at least 48 hours.

  Fourth, the vibration and shock resistance of high-quality pogo pin spring thimble:

  The vibration and shock resistance of high-quality spring thimble is an important performance of electrical connectors. It is particularly important in special application 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. There are clear regulations in the relevant test methods. In the shock test, the peak acceleration, duration and shock pulse waveform, as well as the interruption time of electrical continuity should be specified.
