Now there are more and more devices, and different devices have different interfaces and ports. Take TYPE-C waterproof female socket as an example. Type-C is a type of USB interface, because of its fast transmission speed and high power. High transmission efficiency, dual The face insertion (always reverse insertion) function is very popular. Due to the product characteristics of the interface, the waterproof requirements of the TYPE-C waterproof female seat are very high. If the waterproofness is not good, there will be a risk of water leakage, which will affect the consumer experience. At present, the waterproof test method of TYPE-C waterproof female seat includes two methods: laboratory real immersion method and air tightness test using port\/interface waterproof tester.
The real water method is in contact with water, the operation is complicated, and it is generally not used for batch testing. The general air tightness testing method is to use an interface waterproof testing machine for type-c interface\/port testing, because the testing medium of the interface waterproof testing machine is compressed air, etc. Clean gas. Molecular particles are much smaller than water particles and detection is more precise. It can be combined with high precision sensors. Check for small leaks.
When using the interface waterproof tester, it is generally necessary to customize a test fixture according to the tested interface, so that the port waterproof tester of different customized test fixtures can be used. Many different types of ports or interfaces have been tested. Moreover, at different levels of testing Only need to adjust some parameters of the port waterproof testing machine to complete the port air tightness test.
Taking the IP67 waterproof test of the TYPE-C waterproof female seat as an example, the air tightness test process is described: the IP67 standard is a water depth of 1 meter (the test pressure is 1 meter) and is set at about 10kPa). Generally, the pressure will be increased during the test process. Under the pressure of 15-20kPa, connect the test fixture to the Type-C interface air tightness tester to test the waterproof performance. After setting the test parameters, the Type-C product to be tested can be put into the test mold for testing .The specific test procedure is to put the Type-C interface product to be tested into the fixture, press the tool start button, the cylinder automatically presses down the sealing ring, and the side cylinder realizes sealing. Air tightness tester) realizes automatic detection according to the set parameters.
If there are air bubbles in the water tank, it is proved to be unqualified. If there are no air bubbles, it is proved to be qualified. After the test is over, the oil cylinder is automatically lifted, the operator takes out the product, puts it in the next product, and continues the next round of waterproof testing.
