Abstract

The utility model provides a non-trip plug and socket, which do not loosen in despite of any pulling. The plug is added and provided with an inverted hook at the front of the two prior inserted bar. The socket is provided with a plastic organ button on the side of each prior jack. A gooseneck spring inverted coupon which is made by a rotary spring and a copper strip is arranged in every jack of the socket. A flat power supply chip which is one millimeter is arranged on each jack of the socket. The power supply chip is communicated with every jack. The inner end of the plastic organ button arranged on two sides of the socket is connected with the bottom of a gooseneck rotary spring inverted coupon. When in use, the plastic organ button arranged on two sides of the socket is pressed by fingers and the spring inverted coupon bounces upward. If the plug is inserted into the jack and fingers are loosened, the inverted coupon is hooked with the inverted hook of the plug. So the plug does not fall off.

Description

Pull-off plug socket not

Technical field the utility model relates to a kind of energized device, especially can adeciduate plugs and sockets.

Background technology

At present, two inserted links of commercially available plug are staight shanks, the power supply copper sheet of the both sides jacks the inside of socket is tight by three coil tension springs extruding on each limit, if plug is inserted in the socket the inside, socket is new also effective, and the time one is long, the copper sheet of the inside has been inserted pine by plug, just don't work, plug just comes off easily, gives in the work and brings inconvenience.

Summary of the invention

The purpose of this utility model provides a kind of caducous plugs and sockets of not allowing, and it not only sticks in does not firmly take off.And be suspended on the aerial electric wire of pulling arbitrarily and also do not come off, its purpose is to realize like this.Respectively establish one to hook in two inserted link lower ends of existing plug, be equipped with and socket both sides jack inside play a part to catch on mutually to lacing film, the surface of socket is an indicator light, the jack on power switching device and both sides, in the internal structure of socket, the upper end is that electric wire is imported and exported, the electric wire clamping piece, left upper end is an indicator light, power switching device of middle arrangement, the structure role is interconnected between them, and respectively there is a flat power supply sheet that connects each jack on both sides below the power switching device.Positive and negative circuit on the power supply sheet power switching device of ining succession, the jack on socket both sides the inside all be provided with goose neck formula shape that a rotating spring and copper sheet make to lacing film, the side of each jack all is provided with a plastics office button, the lower end that one of the inside of button is being close to spring to lacing film, if plug is inserted in the jack the inside, as long as press the machine-operated button of tight plastics with two fingers, just up upspring to lacing film, plug has just injected, unclamp finger, just caught on mutually to lacing film with to hook, plug just can't be extracted, unless press plastics office button.The two ends, the back side of socket respectively are provided with " a 8 " font apron

Owing to adopt such scheme, can when work, remove from because the inconvenience that plug brings on often coming off to work.

The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.

Among the figure: 1. electrical wiring, 2. power supply is imported and exported, 3. the clamping piece screw, 4. electric wire clamping piece, 5. indicator light, 6. tight lid screw, 7. mains switch apparatus screw, 8. mains switch, 9. power switching device, 10. plastics offices button, 11. goose neck formula rotating springs be to lacing film, 12. flat power supply sheets, 13. jack, 14. edges lids " recessed " are located, and 15. circuits are imported and exported, 16. plug tightly covers screw, 17. squeeze in, 18. plug electric wires, 19. inserted links, 20. inserted link is to hook, " 21. 8 " type apron, 22. rotary off-normal springs, 23. rotary off-normal spring axis, 24. the jack hole wall, 25. close lid.

Embodiment

In Fig. 1, plug electric wire 18 is imported and exported the inner of 15 straight-through two inserted links 19 through circuit.Plug tightly covers screw 16 17 to be tightened squeezing in, so that inserted link 19 tightly is buckled in 17 the insides of squeezing in.Inserted link is to linking up with 20 for playing the effect of catching on mutually.

In Fig. 2, power supply imports and exports 2 in the top of socket, and indicator light 5 is placed in left upper end, about tightly covering screw 6 and being arranged on below the indicator light 5 in the middle of each one and the lower end one.Power switching device 8 is arranged on the middle of tight lid screw 6 under slightly, and plastics office button 10 is arranged on the side on socket both sides, and each is horizontal in jack 13.

In the embodiment shown in fig. 3, electrical wiring 1 imports and exports 2 at process power supply clamping piece 4 direct power derailing switches 9 through power supply, clamping piece screw 3 tightly is screwed in above the electric wire clamping piece 4, be in order to guarantee that electrical wiring 1 is not loose outward, electrical wiring 1 is sent to indicator light 5 again through power switching device 9, as long as press mains switch 8 with hand, indicator light 5 is with regard to light yellow or extinguish, whether indicator light 5 acts on switches on, mains switch 8 acts on as emergency and has little time to pull the plug out of the socket, the power supply that just loses no time to put out tightly covers screw 6 and acts on and tighten closing of socket and cover 25.Mains switch apparatus screw 7 is provided with in order to tighten power switching device 9, plastics office button 10 is arranged on the dual-side of socket, each button is horizontal in being connected the lower end of the goose neck formula rotating spring of jack 13 the insides to lacing film 11, the moving both sides plastics office button 10 as long as press...with one's finger during use, goose neck formula rotating spring is just up upspring to lacing film 11, plug is inserted, unclamps finger, just and inserted link catch on mutually to linking up with 20.Flat power supply sheet 12 straight-through each jack 13 of two 1 millimeters thick below electrical wiring 1 is connected through power switching device 9 again.Jack 13 is the three phase mains jack in the middle of the socket lower end.Socket edge lid " recessed " is located 14 and to be covered 25 and close up and do not have the space to be provided with in order to close.
