AI Technical Summary

Technical Problem

Existing USB connectors are susceptible to moisture, condensation, and rain in outdoor devices, leading to contact corrosion, signal instability, and device damage.

Method used

A dual waterproofing strategy is adopted: static waterproofing is achieved at the front end through a waterproof baffle and sealant, while dynamic compression waterproofing is achieved at the rear end through a tail cap, nut, and waterproof gasket. Combined with structures such as annular grooves and baffles, the sealing effect is ensured.

Benefits of technology

It achieves full-path deep waterproofing, improves production yield and product consistency, enhances mechanical durability and electrical connection reliability, and isolates the impact of mechanical stress on the circuit board.
