AI Technical Summary
Technical Problem
When the existing instrument waterproof structure meets the creepage distance requirements, it is easy to increase the depth of the waterproof tank, which in turn affects the waterproof effect and instrument volume.
Method used
Design an instrument waterproof device, by setting a double-layer waterproof ring and creepage retaining wall on the face cover, bottom cover and battery cover, the assembly position of the waterproof ring is optimized, the water penetration distance is reduced, and the creepage distance is extended.
Benefits of technology
It effectively reduces the distance from water penetration into the instrument, reduces the instrument volume, improves waterproofing effect and insulation strength, and meets the needs of high waterproofness and small volume.
