Why can W series connectors work under 300 meters of water?

The W series connector adopts a special thread locking connection method. It is designed with triple seals inside and outside. The outer large sealing ring is designed as the first weight. Tighten the sealing ring to squeeze the sealing ring to achieve a waterproof and anti-fouling sealing effect. The head of the plug is designed with double sealing rings as the second and third weights. After the headers are inserted into each other, the sealing ring and the inner wall of the socket are evenly squeezed to achieve a sealing effect to prevent water. In addition, the tail of the plug is also designed with a gasket for sealing when it is welded and assembled with the cable, and the internal glue is filled and sealed after injection molding.
