Abstract

The utility model relates to an ultra-thin safety plug and socket of the connector of an electric appliance, which is characterized in that a plug box is provided with a pull cover plate with a locking device; the pull cover plate can be opened; conductors on the bottom cover of the plug is led out in an inclined direction and the surface cover of the socket is injected with invagination space of the socket; the invagination space of the socket corresponds to the plug. When the plug and the socket are matched for use, the ultra-thin safety plug and socket are only higher to 3.5 mm than the height of a wall surface; then the ultra-thin safety plug and socket can avoid being damaged. The utility model is favorable to the arranging of indoor furniture. The cover of the socket is a smooth surface. The utility model has the advantages of beautiful shape and long service life. Besides, the ultra-thin safety plug and socket can prevent electric shocking of children.

Description

Ultrathin safety plug, socket

The utility model relates to electrical connector, specifically a kind of ultrathin safety plug, socket.

At present circulate the on the market plug that uses of China is upper casing and goes to the bottom and embed the fastening combining structure of the whole screw of copper-base, the plug casing height is generally more than 15 millimeters, exceed the ledge of metope, not only influenced putting of furniture, also easily clashing and breaking are broken, and exposed electrified body is very dangerous, the plug top edge of public use is outwards protruded for holding conveniently, but teenage sometimes children can imitate the adult and pull up plug, and hand bumps electrode and gets an electric shock danger close when partly unpluging state.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of housing is thin, anticollision and provide, ultrathin safety plug, socket safe in utilization, attractive in appearance.

The purpose of this utility model can reach by following measure:

N-Side surf is to be equipped with to turn on the plug box of smooth surface to open the cover plate that draws of pulling out plug, draw the cover plate lower end to cooperate by locking device with the plug box, locking device can be magnetic-type two relevant positions that magnetic patch sticks on housing and draws lid with epoxy that are about to, it also can be the grab elastic force type, with the horizontal inclined-plane that pushes away locking device of thumb, throw off grab, press down with forefinger simultaneously and draw cover plate, hook cylinder top panel is dug automatically, ultrathin safety plug housing height only is 1/2 of an ordinary plug, promptly 7～8 millimeters.Lead on the plug bottom is through the oblique outlet of plug wire hole, to reduce backguy stress, ultrathin safety socket comprises that the socket chipware identical with common wall formula plane socket matches with the socket cover, but socket surface cover be injected with corresponding socket with plug cave in the space and tiltedly below have the pressuring line groove that can put into lead.

Accompanying drawing and description of drawings:

Fig. 1 is the utility model plug perspective view.

Fig. 2 is the utility model socket perspective view.

Among the figure: 1-draws cover plate, 2-locking device, 3-plug box, 4-plug wire hole, 5-plug bottom, 6-plug line pressing bolt, 7-plug line ball curved surface, 8-links up with cylinder, and 9-tightens boss, the 10-plug casing, 11-trade mark plane, 12-hook cylinder embeds mouth, 13-plug screw, 14-plug electrode, 15-location notch, the 16-terminal screw, 17-socket cover, 18-pressuring line groove, 19-socket core body, 20-socket line of fall groove, 21-socket electrode shell, the 22-socket space of caving in, 23-socket mounting screw, 24-electrode hand-hole, 25-wiring square column.

The utility model is described in further detail below in conjunction with accompanying drawing embodiment:

Draw cover plate 1 and plug casing 10 to be the ABS moulding in the ultrathin safety plug socket as shown in Figure 1, the plug casing side is the smooth arcuate cambered surface, can disperse to clamp the pull out force of carrying on the side and producing effectively, make and firmly point slippage, adult, child can not directly pull up it, or outwards pull out one section, avoid the hand palpate.This plug locking device is magnetic-type, with epoxy resin two little magnetic sheets are sticked at respectively and to draw cover plate and plug casing opposite position, draw cover plate 1 rear portion that two cylinders are vertically downward arranged, two chucking boss 9 are established in the inboard, draw cover plate hook cylinder 8 to insert two hook cylinders vertically downward and embed mouth 12, firmly press down, chucking boss 9 is snapped in the plug casing 10 tighten in the associated groove.Plug bottom 15 also is a moulding, and the plug electrode 14 of metal is a stamping parts, during the injection moulding bottom, embed three copper-bases and be injection molded into one, connect three lead-in wires and put into oblique plug wire hole 4, oblique outlet reduces backguy stress, and cooperates conveniently with socket pressuring line groove 18, bottom 5 is snapped in the plug casing 10, the plug screw 13 of screwing on becomes one housing and bottom, 2 plug line pressing bolt 6 is screwed again, it is tight to use line pressure, and plug installs.

Socket core body 19 is a moulding, three electrode copper sheets are put into three socket electrode shells 21 of relative isolation, be connected with three wiring square columns 25 with screw, again three terminal screws screwed in the wiring square column silk mouth, fastening with mounting screw and socket core body 19 square surfaces.With epoxy resin socket core body 19 planes are sticked in the chamber, 17 end of socket cover, promptly finish the installation of socket, be fixed in wall with socket mounting screw 23.During use mounted plug electrode 14 alignings are inserted pressing in the socket electrode hand-hole 24, draw lead and put into socket pressuring line groove 18, because the utility model socket cover 17 has the socket space 22 of caving in, therefore plug casing 10 protrusion heights only are below 3.5 millimeters, put and avoid the plug breakage favourable to furniture.

In the time of need pulling up plug, earlier with the insulated conductor translation, make lead all withdraw from socket pressuring line groove 18, lie on the socket cover 17, because drawing cover plate is magnetic-type locking mode, only need press down and draw cover plate hook cylinder 8 end faces, the plane rotates up 90 degree, drawing cover plate hook cylinder 8 all to be absorbed in the hook cylinder simultaneously embeds in the mouth 12, cylinder itself also upwards rotates 90 degree in housing, parallel with housing, draw cover plate 1 to dig automatically and be erected on the plug casing 10, draw cover plate 1 two sides firmly promptly to pull the plug out of the socket with the hand clamping.

The utility model has following advantage compared to existing technology:

1, this plug casing is thin, anticollision, the putting of not overslaugh indoor furniture.

2, the utility model bayonet cap is smooth curved surface, can prevent children from getting electric shock, uses Safety.

3, ultrathin safety plug, socket are handsome in appearance, dependable performance, long product lifecycle.
