The waterproof wire connector air-tight detection equipment is a USB interface that supports high current and high voltage charging. This type of waterproof wire connector requires high water resistance during the production process, so it is necessary to use the waterproof connector air-tight detection equipment to It conducts a waterproof test.

The waterproof wire connector air tightness testing equipment is also called the joint air tightness detector. It determines whether the product is leaking by inflating the product and sensing the change of the internal pressure value. In layman's terms, it uses the principle of air pressure to simulate water pressure. Waterproof wire connector air tightness testing equipment for waterproof performance testing.

A test instrument suitable for air tightness testing equipment of waterproof wire connectors has been developed and has been put into use.

1. Taking into account the shape and size of the connector air tightness testing equipment, the corresponding tooling fixtures are made. The connector air tightness testing equipment can be placed in the tooling fixtures, and the connector can be judged by inflating its interior. Whether the air-tightness testing equipment is leaking.

2. The purity of the gas source must be maintained during the test, free of impurities, water, and oil, and the stability of the gas source pressure must be maintained to ensure the accuracy of the test.

3. The test process is very simple. Place the waterproof wire connector air tightness testing equipment on the tooling and jig. When the upper and lower molds are closed, inflate the tooling and jig. If the pressure value and leakage value decrease, the air tightness tester It will display NG; if the pressure value and leakage value change very little and are within the specified range value, it is qualified.
