Description

The safety powr supply plug socket

The utility model relates to a kind of power connector, relates in particular to a kind of safety powr supply plug socket.

Existing plug and socket of power source has two kinds usually, a kind of is two-pin plug and socket, they patch more convenient, the zero line of device shell but they can't be met sb. at the airport, another kind of three-pin plug and socket, they patch also more convenient, but since traditionally three sockets also often and two-pin plug cooperate usefulness, the zero line of device shell so also can't meet sb. at the airport makes that the shell with the machine of these attaching plugs and socket has electric charge because of ground connection is bad; Simultaneously, because interior live wire intermediate plate of socket and ground wire intermediate plate are in same plane, therefore, in the socket of innocent child, misplug into conductor at charged socket, or, make it to form the loop, thereby cause the casualty accident of getting an electric shock owing to accidentally a conductor is fallen into the socket of charged socket.

The purpose of this utility model is achieved in that a kind of safety powr supply plug socket, comprises plug and the socket that cooperates with it, is characterized in, described plug is combined by an insulation handgrip and at least one group of inserted sheet and at least one group of power supply plug wire; The described inserted sheet of respectively organizing is wrapped up in formation layer by layer mutually by multilayer material, its rear portion of inserted sheet after wrapping up in mutually from the insulation handgrip an end be inserted to the insulation handgrip in, its front portion by layers of material from the inside to surface segmentation line up the in-line shape; Described respectively organize the power supply plug wire be connected with the inserted sheet rear end back from the insulation handgrip the other end draw; Described socket is combined by seat shell and at least one group of intermediate plate and at least one group of power supply wiring that is fixedly installed in the seat shell of a rectangle; At least be provided with a socket on the upper surface of described seat shell; The described intermediate plate of respectively organizing is formed by two intermediate plates and is fixedly installed one on the other in the present shell; The center being aligned of described socket and two intermediate plates; Described respectively the group drawn outside the seat shell after power supply wiring is connected with intermediate plate.

The utility model with the zero line ground connection of socket, therefore, can be avoided the accident that takes place because of the machine electric leakage owing to the zero line with machine casing and plug joins fully; Simultaneously, join owing to be arranged on the spring clip and the zero line on socket top, the spring clip and the live wire that are arranged on the socket bottom join, therefore, even innocent child inserts conductor in charged socket outlet, this conductor at first joins with zero line, collides with live wire in reentering then, at this moment, power supply on the live wire flows to zero line by lead, cause short circuit,, thereby avoid suffering Danger Electric shock risk blown fuse; In addition, the inserted sheet of plug front portion is made flat shape, makes in the both convenient insertion socket of plug, and keeping with spring clip again is maximum contact-making surface; And the plug of in-line and socket can be combined into the plug and the socket of three phase mains at an easy rate.
