Described plug casing is provided with circumferential anticreep boss, makes the anti-positive stop lug boss that pulls out lid be strapped in putting in place between the boss of anticreep boss and plug body mount pad.
Described plug body mount pad is provided with several jack posts that is used to install jack strip, and, have at least the external diameter of two jack posts not wait, described socket mount pad be provided with the jack post one by one corresponding matching dodge the hole.
The utility model second technical problem to be solved is: a kind of syndeton that can indicate the charging inlet of plug-in position well is provided.
For solving second above-mentioned technical problem, the technical scheme that the utility model adopts is: described circular socket tube is provided with inwardly protruding portion along the plug direction, is provided with cannelure between described circular socket tube and the socket mount pad; Described plug body mount pad is provided with the circular plug tube that matches with cannelure, and the circular plug tube is provided with the portion that caves inward that matches with inwardly protruding portion along the plug direction.
The utility model the 3rd technical problem to be solved is: a kind of syndeton that can prevent the charging inlet of plug water inlet is provided.
For solving the 3rd above-mentioned technical problem, the technical scheme that the utility model adopts is: described plug body mount pad offers the annular seal groove that matches with the end face of plug casing facing to plug casing, is provided with sealing ring in the annular seal groove.
The beneficial effect of the utility model is: the utility model cooperatively interacts through the anti-circular socket tube that pulls out lid and Socket casing, reaches the purpose that prevents that mistake from pulling out, and has eliminated potential safety hazard.In addition, through will at least two the jack post that do not wait of external diameters and with the socket mount pad on match in the hole of dodging of corresponding matching one by one with the jack post, prevented that effectively contact pin and jack from misplacing, and reaches the purpose of safe handling; The inwardly protruding portion on the circular socket tube and the portion of caving inward of circular plug tube cooperatively interact, and have played the effect of indicating plug-in position well, greatly facilitate the grafting of joint and socket, use very convenient.In addition, be arranged on the sealing ring in the annular seal groove on the plug body mount pad, can prevent the plug water inlet effectively, prolong the useful life of charging inlet.
