Electronic devices are developing rapidly, and many smart devices have introduced waterproofing, and high-quality pogopins are connectors in smart devices. It has a waterproof function. The waterproof of high-quality pogo pins mainly depends on its strong performance. Let's understand the reasons why high-quality pogo pins are waterproof.

1. High temperature resistance of high-quality pogo pins:

Currently, the working temperature of high-quality pogo pins is 200℃, and the low temperature is -65℃. Because during the connection work, the current will have heat at the contact point, causing temperature rise, so it is generally considered that the working temperature will be equal to the sum of the ambient temperature and the temperature rise of the contact point. In some regulations, the allowable temperature rise of the connector under the rated operating current is clearly specified.

2. The humidity resistance of high-quality pogo pins:

The intrusion of moisture has an impact on the insulation performance of the connector, and it will corrode the metal parts. The constant heat and humidity test conditions are relative humidity 90%~95%, temperature +40±20℃, and the test time is based on product regulations, at least 96 hours. The high-quality pogo pin alternating damp and heat test will be more stringent.

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

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

Four. Vibration and shock resistance of high-quality pogo pins:

Vibration and shock resistance of high-quality pogo pins is an important performance of electrical connectors. It is particularly important in special use environments such as aviation and aerospace, railway and road transportation. It is to test the robustness of the mechanical structure of electrical connectors. An important indicator of electrical contact reliability. It will be clearly stipulated in the relevant test methods. In the shock test, there are specified peak acceleration, duration and shock pulse waveform and electrical continuity interruption time.
