The rapid development of electronic equipment, many smart devices have launched a point of purchase. High-quality waterproof pogo pin is a connector in smart devices, with waterproof function, high-quality high-quality pogo pin waterproof performance Mainly depends on its power to understand the reasons why high-quality pogo pins are waterproof.


1. High-quality pogo pin with high temperature resistance:

The current working temperature of high-quality pogo pins is 200, and the low temperature is -65. Since the current will generate heat at the contacts during connection work, causing heat, it is generally considered that the operating temperature is equal to the sum of the ambient temperature and the heat generated by the contacts. In some regulations, the allowable temperature rise of the connector below the rated working current is clearly stipulated.

High quality pogo pins, how to use pogo pins

2. High-quality pogo pin moisture-proof:

Water intrusion will affect the insulation performance of the connector and corrode metal parts. Constant temperature and humidity test conditions are 90%-95% relative humidity, temperature +40±20℃, and the test time is at least 96 hours according to the product regulations. High-quality pogo pin alternating heat and humidity test will be more stringent.


3. Salt spray resistance of high-quality pogo pins:

When a high-quality pogo pin works in an environment containing moisture and salt, its metal structure and contact surface treatment layer may undergo galvanic corrosion, which affects the physical properties of the connector And electrical performance. In order to evaluate the ability of electrical connectors to withstand such environments, a salt spray test is specified, that is, the connector is hung in a temperature-controlled test box, and compressed air is sprayed with a specified concentration of sodium chloride solution to form a salt spray atmosphere. The exposure time is determined by product specifications, at least 48 hours.


4. High-quality pogo pin anti-vibration and shock resistance:

The vibration and impact resistance of high-quality pogo pins is an important performance of electrical connectors. It is especially important in special use environments such as aerospace, railway and road transportation. This involves testing the robustness and electrical contact of the electrical connector. An important indicator of mechanical structure reliability. It will be clearly stated in the relevant test methods. In the shock test, there are specified acceleration, duration, shock pulse waveform and electrical continuous interruption time.
