With the increasing requirements for high-frequency testing of cables in the consumer field, especially the quality of the end treatment of shielded wires, it will affect the testing performance, and is currently the most common and labor-intensive process. It requires hot stripping, peeling, breaking up, brushing braided wires up and down, twisting weaving, and cutting aluminum foil, which requires a lot of manpower investment and increases the workload and difficulty of operators. Quality stability is even more difficult to control, Type-C interface innovation is a highly deterministic opportunity in the field of consumer electronics. Compared to the interface standard Lightning currently used by Apple on the iPhone, USB type-C has significant advantages in cost, fast charging, compatibility, and other aspects. The introduction of E-Marker chips will make up for its security shortcomings, so its use in iPhone products will be a long-term trend.

The waterproof type-c connector has an IP parameter during the production process, which means the level of waterproofing and dust prevention. The higher the value, the stronger its waterproof ability. When producing such products, USB connector manufacturers will use sampling methods to conduct waterproof and airtightness testing on the products to determine their IP parameters. At present, the waterproof and airtightness testing tool for waterproof type-c connectors is an airtightness tester, and the specific testing methods and steps are as follows.

The water depth for waterproof testing is determined based on the IP value designed for the waterproof type-c connector. For example, the testing depth of IP67 standard should be 1 meter and the pressure should be about 10kPa, but in actual testing, the pressure will be appropriately increased to 15kPa. The specific testing steps are: place the waterproof type-c connector to be tested in the fixture, press the start button, the cylinder will automatically press down, tighten the sealing ring, seal the side cylinder, and then start the air tightness tester. The instrument will automatically test according to the set parameters. As soon as the testing time arrives, the screen will display the leakage value of the tested product, and the alarm indicator light will indicate whether it is qualified. After the experiment, the cylinder automatically lifts and the operator takes out the product.

During the testing of waterproof type-c connectors, relevant Chinese standards should be followed to ensure that the allowable leakage does not exceed 0.05KPa. The intake time is 2 seconds, the stabilization time is 2 seconds, the testing time is 5 seconds, the exhaust time is 1 second, and the overall testing time is controlled within 10 seconds. If the detected leakage value exceeds the standard, the alarm indicator light of the airtightness tester will light up, reflecting that the USB connector manufacturer's product is not qualified. When the qualification rate of the waterproof test is lower than the standard requirements, the manufacturer needs to recheck the structural design and production process of the waterproof type-c connector to further improve the waterproof and airtightness of the product.

Several characteristics of waterproof type-c connectors:

1. It can provide various voltage and current specifications of power supply, with a limit value of up to 100W.

2. Symmetrical connection, capable of positive and negative connections, capable of withstanding 10000 repeated plugins and unplugs.

3. High bandwidth, data transmission speed up to 10gbit/s, and current specification values ranging from 3A to 5A.

4. The channel configuration is flexible, such as determining the direction of interface insertion, interface power supply function, Atermatic mode, and peripheral mode.

5. Support non USB signal transmission and various OEM product customization modes through waterproof type-c connectors.

6. Compatibility, the USB switch can connect different types of interfaces.

7. Small size, thinner than type-a and type-b, which can greatly reduce the size of electronic products.

A waterproof type-c connector refers to a connection interface with certain waterproof functions, which belongs to a type of USB connector. Since 2014, the USB IF Association has developed a new generation of interfaces to meet the challenges of faster interfaces. After the launch of the waterproof type-C connector, it has attracted attention from various industries. Industry professionals believe that this new interface will bring new electronic connection modes.
