AI Technical Summary

Technical Problem

In existing power adapters, the sealant can loosen due to frequent shaking during use, allowing moisture and dust to seep in, affecting the waterproofing effect and consequently impacting lifespan and safety.

Method used

It adopts a dual fixing structure, which connects the outer fixing block with the outer slot and the inner fixing block with the inner slot. Combined with the design of the potting groove and the cover plate, it uses epoxy resin to seal, ensuring airtightness, and the shaking of the wires will not affect the sealing.

Benefits of technology

It achieves stable sealing performance, with a waterproof rating of IP67, thus improving the lifespan and safety of the power adapter.
