Nowadays, there are more and more devices, and different devices have different interfaces and ports. For example, the USB type-c interface is a type of USB interface that is widely welcomed due to its high transmission speed, greater power transmission efficiency, and double-sided plug (never plug back) function. Due to the product characteristics of the interface, there are very high requirements for waterproof testing of the type-c interface. If the waterproof performance is not good, there will be a risk of leakage, which will affect the user experience. At present, there are two types of waterproofing testing methods for type-C: laboratory real water immersion method and air tightness testing using port/interface waterproofing testing machine.

The real water method is in contact with water, and the operation is complex. Generally, it is not necessary to conduct large-scale testing. The common airtightness testing method is to use an interface waterproof testing machine for type c interface/port detection, because the detection medium of the interface waterproof testing machine is clean gas such as compressed air, and the particle size is much smaller than that of water particles, making the detection more precise. With high-precision sensors, small leaks can be detected.

When using an interface waterproof testing machine, it is generally necessary to customize a testing fixture based on the tested interface. This way, a port waterproof testing machine can be used with different customized testing fixtures to complete various types of port or interface testing. And when testing different levels, only adjusting some parameters of the port waterproof testing machine can complete the airtightness detection of the port.

Taking the IP67 waterproof test of the type-c interface as an example, let's talk about the airtightness testing process: the IP67 standard requires a water depth of 1 meter (the test pressure is set at around 10kPa).

During general testing, the pressure will be increased. At a pressure of 15-20kPa, connect the testing fixture to the Type-C interface airtightness testing machine and conduct a waterproof performance test. After setting the testing parameters, the Type-C product to be tested can be placed in the testing mold for testing. The specific testing steps are to place the type-c interface product to be tested in the fixture, press the start button of the fixture, and the cylinder will automatically press down to tighten the sealing ring. The side cylinder will achieve sealing, and start the GOEL type-c interface airtightness testing machine (airtightness tester) to achieve automatic detection based on the set parameters.

If there are bubbles in the sink, it is considered unqualified. If there are no bubbles, it is considered qualified. After the inspection is completed, the cylinder automatically lifts, and the operator takes out the product and puts it into the next product to continue with the next round of sealing/waterproofing testing.
