[0021] (2) The DC connector socket of the outdoor power connector of the present invention is welded on the circuit board, and then the metal shell of the flange assembly is inserted into the DC connector socket from the outside of the chassis, and then the metal shell is connected to the chassis shell screws set outside the DC connector socket to fix it on the chassis shell. This is different from the existing products that fix the socket as a whole to the chassis, and then use the locking screws to connect the internal components of the chassis with the socket terminals. This installation method can also make the internal assembly simple. In addition, a sealing ring I is installed on the terminal area between the plastic back cover of the socket and the plastic base of the socket, and the signal pin is also glued. After assembly, the socket contact can be waterproof. Through this installation method and structure, the socket can be waterproof as a whole. BRIEF DESCRIPTION OF THE DRAWINGS
