A waterproof socket and matching plug in a car, mainly composed of a matching plug with a metal insert, a top end cover with a jack, a waterproof barrel wall, a bottom screw cover, a copper core tray with a copper core, a spring and A socket composed of spiral wires. The bottom screw cap is threadedly connected to the wall of the waterproof barrel, the hollow column of the bottom screw cap and the hollow column of the top end cover form a cavity, and the cavity is provided with a spring. The top end cover is glued to the copper core tray with a copper core, the top end cover protrudes from the waterproof barrel wall through the spring push, and the top end cover limit block is fixed at the maximum stroke by the limit block of the waterproof barrel wall Location. The metal blade of the plug is mated with the copper core through the socket, and the copper core is connected with the power supply through the spiral wire collected in the main wire. The main body of the plug is threadedly connected with the wall of the waterproof barrel. The main body of the plug rotates downward, driving the top end cap to rotate downward until the thread of the main body of the plug and the thread of the socket are completely screwed together, so that the interface between the plug and the socket is completely sealed and completely waterproof.
Description
technical field [0001] The invention relates to a socket and a matching plug, in particular to a waterproof socket and a matching plug in an automobile. Background technique [0002] At present, a large number of automobiles have been equipped with a 220V power supply. The existing commonly used automobile sockets and matching plugs are basically waterproof through the tight fit between the socket and the plug or the addition of a sealing ring. However, in some special cases, because the cooperation cannot be completely waterproof, it is easy to cause a short circuit in the socket or electrical appliances, which has potential safety hazards, and it is easy to cause the plug to fall off due to external force during the charging process. Contents of the invention [0003] In order to overcome the shortcomings in the above-mentioned background technology, the present invention provides a waterproof socket and a matching plug in an automobile. [0004] The technical solution ...
