First, connect the wire rod to the power female terminal 7 by riveting, insert it into the corresponding position on the mother rubber core 9, then put the mother rubber core 9 into the corresponding groove of the mother shell 4, and then pass the wire rod through the waterproof hole of the mother shell 4 in turn. And the sealing ring 3, the jaw 2, the nut 1, tighten the nut 1, and then pre-install the custom screw 5 and O-ring 6. The power male terminal 12 , the ground male terminal 13 and the signal male terminal 14 are pressed into the male rubber core 11 , the male terminals are fixed, and the screws 10 are pre-installed in the corresponding holes of the male rubber core 11 , that is, the assembly of the power connector is completed.

Because there is no screw protection structure for similar products, the plug needs to be locked on the socket, and it cannot be locked on the socket surface. Therefore, two copper nuts need to be embedded in the socket. Because the application has innovatively designed the screw protection structure, it is not necessary to directly lock the nut. It is locked on the socket surface, which reduces the product cost and the socket injection molding process. The sockets of similar products have a flange design, which requires protection design for the socket and socket surface. The innovative design of this application is that the flange of the socket edge is partially cut off, and the entire socket is contained within the outer shell of the plug, and the plane of the plug and socket is sealed. , Such as these not only save the height space on the 4 corners, but also save the waterproof structure of the socket, the product cost is lower, and there are fewer quality problems due to the reduction of a protection.
