The application scenarios of electronic devices are becoming increasingly complex and diverse, with an increasing number of underwater operations. Waterproof performance has become an important characteristic of electronic products. As a connecting component between electronic devices, the waterproof performance of USB connectors is also crucial. In harsh environments, waterproof USB connectors can enhance the stability of device connections and maintain normal device operation.
How to accurately determine the waterproof level of USB connectors? The following are the testing steps:
Step 1: Determine the testing conditions
Based on the IP waterproof rating designed for the USB connector, specify the corresponding test water depth and pressure values. To ensure the rigor of the testing, the pressure can be slightly increased.
Step 2: Implement testing
Fix the waterproof USB connector to be tested in a dedicated fixture.
Start the testing system, the cylinder automatically presses down, tightly seals the sealing ring, and ensures that the side cylinder is completely sealed.
Start the airtightness tester, and the instrument will automatically perform testing based on preset parameters. After the test is completed, the screen will display the leakage value of the product, and the alarm indicator light will prompt whether the product is qualified.
Step 3: End detection
After the test is completed, the cylinder will automatically rebound, and the operator can easily remove the product to complete the entire testing process.
It is worth noting that only USB connectors that pass the above tests can be officially labeled with the corresponding waterproof level, ensuring their reliable performance in various environments.
