[0002] The USB airtightness tester is a device specifically designed to verify the sealing performance of USB interfaces and related products. Airtightness is crucial for electronic devices. Good airtightness prevents impurities such as dust and moisture from entering the device, thereby ensuring its proper operation and longevity. This tester accurately measures gas leakage in USB products under specific pressure conditions to determine whether they meet airtightness standards.

[0003] Existing USB air tightness testers have the following problems when in use: they are usually designed with a single-port test structure and can only perform a single USB air tightness test at a time. At the same time, they lack positioning and assembly components and often require manual positioning and assembly. Moreover, on large-scale production lines, the test speed of the tester is relatively slow, which may become a bottleneck in production efficiency and cannot meet the needs of rapid testing.
