USB type-c, abbreviated as type-c, is a type of USB interface that can be used for fast charging and efficient data transmission. Moreover, the USB type-c interface can be easily plugged and unplugged on both sides, meaning there is no front or back, making it convenient to use. Currently, mobile phones are gradually using the type-c interface, as it supports a power output of 100W. In recent years, the USB type-C interface has been applied from mobile phones to other devices, such as tablets, laptops, headphones, and other electronic products. If the waterproof performance is not good, there is a risk of electric leakage, which affects the use. Therefore, it is necessary to conduct airtight and waterproof testing on the USB type-C interface.

Due to the small and slim size of the type-c interface, some products have grooves on the edges and slots inside, which places high demands on fixture design. However, there are a large number of products with small size in type-C, making it easy for the upper and lower parts to take up time. To improve the efficiency of airtightness and waterproofing testing of the USB type-C interface, there are 2-4 testing ports on the fixture, which can simultaneously test the airtightness and waterproofing of four USB type-C interfaces. The airtight and waterproof testing equipment adopts conventional waterproof testing equipment. If the USB type-c interface needs to meet the IP67 standard, a pressure of around 10.5-20kPa can be used for testing to ensure the product quality of the USB type-c interface.

Waterproof type-c female connector, related to the power supply, data transmission, and data exchange technology fields of electronic products; One end of the upper terminal and the lower terminal are respectively equipped with upper terminal molding and lower terminal molding. An ear buckle is set between the upper terminal molding and the lower terminal molding, and a grounding strip is set on the upper terminal molding and the lower terminal molding. The ear buckle and the other end of the upper and lower terminals are equipped with secondary molding. The outer circumference of the upper terminal molding, lower terminal molding, and secondary molding is equipped with a steel shell, and the outer part of the steel shell is equipped with an outer shell, The shell is equipped with a silicone gasket, which makes the product structure simple, stable, and has a low assembly cost. It effectively prevents moisture from entering the interior of the electronic product, avoiding rust and short circuits of electronic components inside the electronic product.
