What links need to be tested for high-quality waterproof spring thimbles?

　　With the development of electronic devices, many smart devices have launched waterproof as a major buying point, and high-quality pogo pins are used as connectors in smart devices. It has waterproof function, so how is its waterproof function achieved? Woolen cloth? In fact, the waterproof of high-quality pogo pins mainly depends on its powerful performance, so let's follow the editor of Jingcheng Industry to understand why high-quality pogo pins are waterproof.

　　1. High-temperature resistance of high-quality pogo pins: At present, the working temperature of high-quality pogo pins is 200°C, and the low temperature is -65°C. Since the current generates heat at the contact point when the connection is working, resulting in a temperature rise, it is generally believed that the operating 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 at the rated operating current is clearly specified.

　　2. Moisture resistance of high-quality pogo pins: the intrusion of moisture will affect the insulation performance of the connector and corrode metal parts. The constant damp heat test conditions are relative humidity 90%~95%, temperature +40±20℃, and the test time shall be at least 96 hours according to the product regulations. The alternating damp heat test of high-quality pogo pins is more severe.

　　3. Salt spray resistance of high-quality pogo pins: When high-quality pogo pins work in an environment containing moisture and salt, galvanic corrosion may occur on the surface treatment layers of their metal structures and contacts, affecting the physical and electrical properties of the connector. performance. To evaluate the ability of electrical connectors to withstand this environment, the salt spray test is specified. It is to hang the connector in a temperature-controlled test box, and spray the sodium chloride solution with the specified concentration with compressed air to form a salt fog atmosphere. The exposure time is specified by the product specification, at least 48 hours.

　　4. Vibration and shock resistance of high-quality pogo pins: Vibration and shock resistance of high-quality pogo pins are important properties of electrical connectors, which are particularly important in special application environments such as aviation and aerospace, railway and road transportation. It is an important indicator to test the robustness of the mechanical structure of the electrical connector and the reliability of the electrical contact. There are clear provisions in the relevant test methods. The shock test shall specify the peak acceleration, duration and shock pulse shape, as well as the time of interruption of electrical continuity.
