The invention relates to a waterproof insulated connector, which modifies any electrical connection of a power supply, a USB, a VGA, a socket of electric equipment, an SD, an MS, an MMC and the like into a connection that is completely waterproof and insulated. Whether a connector of the electric equipment is connected or not, the plug and the socket are waterproof and can be completely and directly connected in water or other media without damaging the electric equipment and causing electric shock accidents, and multiple electric passages can be insulated from each other. The waterproof performance is realized by an isolating cavity consisting of a gating isolate component made of a dielectric elastomer, a shell and a hollow waterproof ring. The waterproof isolation connector and the method thereof have innovation in technology and lead users to an electric world with high safety and humanization.
