Description

Anti-electric shock socket

Technical field

The utility model relates to a kind of socket, is meant a kind of anti-electric shock socket especially.

Background technology

Traditional supply socket has two kinds, a kind of is that the interior electrode shell fragment of socket exposes behind jack, during use directly with plug insertion socket, this socket is when holding plug insertion socket with hand, run into the plug metal film of having switched on as finger, or child plays with socket because of curiosity, put in jack with sheet metal or finger and touched the socket shell fragment, or touch and expose when plug does not insert jack fully when the plug metal film of jack outside, electric shock accidents can take place.Another kind of socket is to be provided with safety valve behind jack one, and the socket shell fragment of jack the inside is concealed, and the deficiency of existence is: plug insertion socket is relatively being required great effort, and the elderly, disabled person use inconvenience; If child pushes safety valve open with sheet metal simultaneously, metal is easy to just contact with the socket shell fragment, equally electric shock accidents can take place.In a word, all there is potential safety hazard in existing socket.

Summary of the invention

Order of the present utility model ground be at the deficiencies in the prior art, a kind of a kind of anti-electric shock socket safe, easy to use is provided.

The purpose of this utility model is achieved in that a kind of anti-electric shock socket, comprise seat board, be arranged on the jack on the seat board, wherein: be provided with back seat at the seat board rear portion relative with jack, in back seat, be provided with the shell fragment electrode that matches with jack, being provided with in the back seat bottom of shell fragment electrode downside can be by the through hole of plug metal film, be provided with the press-type switch at the back seat rear portion, this press-type switch press the head relative with through hole; Power line is connected with the shell fragment electrode behind the press-type switch.

Press-type switch described in the utility model can be formed by pressing head, insulation crust, insulated connecting rod, retainer spring, two cube electrode sheets, disconnection spring and limiting plate, insulation shell hollow also becomes little down and big step-likely, and limiting plate is arranged on step place in the insulation shell; The middle part is provided with bulge loop on insulated connecting rod, insulated connecting rod is arranged in the insulation shell, its upper end is stretched out insulation shell and is fixedlyed connected with pressing, and the lower end is stretched out limiting plate and fixedlyed connected with a cube electrode sheet wherein, and the disconnection spring housing is located on the insulated connecting rod between bulge loop and the limiting plate; Retainer spring is fixed on the insulation shell bottom, fixedlys connected with another cube electrode sheet in the upper end; Two cube electrode sheets relatively also separate.

The further improvement project of the utility model is: be connected with the shell fragment electrode of another side after live wire, zero line are through the press-type switch, can further improve security performance like this, prevent the generation of electric shock accidents.

The utility model is owing to adopt said structure, and no safety valve, plug insert socket easily, utilizes the press-type switch to be communicated with power supply, plug must be inserted socket fully during use, and socket circuit could be communicated with, and can prevent to point and run into plug metal film; Adopt the staggered form mode of connection, the power line of drawing from the press-type switch is connected with shell fragment electrode under another jack exactly, like this, when promptly using sheet metal to insert one of them jack, if the power line that the press-type switch of this jack back connects is a live wire, when the metal that inserts joins its electrode slice, at this moment a shell fragment electrode at another jack has, and the power line that the shell fragment electrode that is inserted into the jack of sheet metal connects is a zero line, does not have electricity, does not have Danger Electric shock risk; If be inserted into power line that the press-type switch of the jack of metal connects when being zero line, the shell fragment electrode of two jacks does not all have electricity, electric shock accidents can not take place.

The utility model is further described below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of press-type switch in the utility model;

Fig. 3 is a circuit connection diagram of the present utility model.

Among the figure: 1 seat board, 11 jacks, 2 back seats, 21 through holes, 3 shell fragment electrodes, 4 press-type switches, 41 press head, 42 insulation crusts, 43 insulated connecting rods, 431 bulge loops, 44 retainer springs, 45 electrode slices, 46 disconnection springs, 47 limiting plates, 5 mains switches, 6 supports.

Embodiment

As shown in Figure 1, anti-electric shock socket of the present utility model, it is the diplopore socket of a charged source switch 5, comprise seat board 1, be arranged on two jacks 11 on the seat board 1, be provided with back seat 2 at seat board 1 rear portion relative with jack 11, in back seat 2, be provided with the shell fragment electrode 3 that matches with jack 11, being provided with in back seat 2 bottoms of shell fragment electrode 3 downsides can be by the through hole 21 of plug metal film, be provided with press-type switch 4 at back seat 2 rear portions, pressing of this press-type switch 4 is 41 relative with through hole 21, and press-type switch 4 is fixed on the back seat 2 by support 6.

As shown in Figure 2, described press-type switch 4 is by pressing 41, insulation crust 42, insulated connecting rod 43, retainer spring 44, two cube electrode sheets 45, disconnecting spring 46 and limiting plate 47 is formed, insulation shell 42 hollows also become little down and big step-likely, and limiting plate 47 is arranged on step places in the insulation shell 42; The middle part is provided with bulge loop 431 on insulated connecting rod 43, insulated connecting rod 43 is arranged in the insulation shell 42, its upper end is stretched out insulation shell 42 and is pressed 41 and fixedly connected, the lower end is stretched out limiting plate 47 and is fixedlyed connected with a cube electrode sheet 45 wherein, disconnects spring 46 and is set on the insulated connecting rod 43 between bulge loop 431 and the limiting plate 46; Retainer spring 44 is fixed on insulation shell 42 bottoms, fixedlys connected with another cube electrode sheet 45 in the upper end; Two cube electrode sheets 45 relatively also separate.

As shown in Figure 3, power line is connected with shell fragment electrode 3 behind press-type switch 4, live wire L connects mains switch 5 backs and is connected with the lower electrode sheet 45 of the press-type switch 4 on the left side, and the upper electrode sheet 45 of left side press-type switch 4 is connected with shell fragment electrode 3 under the right jack 11.Zero line N connects the lower electrode sheet 45 of the press-type switch 4 on the right, and the upper electrode sheet 45 of the right press-type switch 4 is connected with shell fragment electrode 3 under the left side jack 11; Form the staggered form wiring.

When the utility model specifically uses, turn on the power switch 5, sheet metal on the plug inserts jack 11 and contacts with shell fragment electrode 3, that passes that through hole 21 touches press-type switch 4 presses 41 again, and will press 41 to pressing down, and drives insulated connecting rod 43 and moves down, bulge loop 431 compressions on the insulated connecting rod 43 disconnect spring 46, after sheet metal on the plug inserts fully, 45 contacts of two cube electrode sheets, circuit communication; When pulling the plug out of the socket, insulated connecting rod 43 loses holding power, and the elastic force that compressed disconnection spring 46 produces acts on bulge loop 431, and insulated connecting rod 43 is moved up, and two cube electrode sheets 45 separate, and circuit disconnects.When the utility model was used in Three-hole socket, the ground wire sheet metal can be controlled without press-type switch 4, used a conventional socket shell fragment to get final product.
