Waterproof connector for PCB board end female base

Waterproof Connector for PCB board end female base

What in the end is a waterproof connector, as the name implies is the ability to work underwater connectors, that is, when there is water can also ensure that the current, signal transmission, often seen in LED outdoor, marine, military fields. So what are the more common properties of waterproof connectors?

The most common environmental performance of waterproof connectors are temperature, humidity, salt spray, vibration and shock resistance.Industrial I/O Connectors

1, temperature resistance

The current maximum working temperature of the connector is 200 degrees Celsius, the minimum temperature of -65 degrees Celsius. As the connector works, the current at the contact point generates heat, resulting in temperature rise, so it is generally believed that the working temperature should be equal to the ambient temperature plus the temperature of the contact point.

2、Humidity resistance

The intrusion of moisture has a great impact on the insulation performance of the connector and can easily corrode metal parts. Constant damp heat test conditions for the relative humidity at 95%, the temperature of +40 ± 20 degrees Celsius, the test time according to product regulations for a minimum of 96h.Custom Cables Harness

3、Salt spray resistance

Waterproof connectors in the environment containing moisture and salt work, the metal structure of its parts, contact parts surface plating layer is very electrochemical corrosion, affecting the physical and electrical properties of the connector. Salt spray test is the connector suspended in a temperature-controlled test chamber, with a prescribed concentration of sodium chloride solution with compressed air spray, the formation of salt spray atmosphere, the exposure time specified by the product specification, at least 48h.

4、Vibration and shock resistance

Vibration and shock resistance is an important performance of the connector, in special applications such as aviation and aerospace, rail and road transport is particularly important, it is an important indicator to test the robustness of the connector mechanical structure and electrical contact reliability.

5, other environmental performance

According to the requirements of use, other environmental performance of waterproof connectors are sealing, liquid impregnation and low air pressure.
