Abstract

The utility model relates to an improvement for the existing power socket. The utility model has the technical proposal that a partition board is arranged between an electrode and an outer cover, and an elastic object is arranged between the partition board and the outer cover. A socket hole on the outer cover is closed by the partition board through elastic force. When the plug is inserted in the socket through external force and overcomes the acting force of the elastic object, the partition board and the outer cover relatively move, the socket hole is opened, and the power is conducted. The utility model is safe and the use is convenient, which can protect the insulation property of the socket from being damaged by the pollution of accumulated filth and prevent electric shock accidents caused by the man-made incaution. Simultaneously, the oxidation of the electrode is reduced, a good electrical conductivity is ensured, and the service life of the socket is extended.

Description

Safety socket

The utility model relates to socket and connects device, particularly a kind of safety socket.

No matter existing supply socket is fixed or portable socket, and the socket aperture of making for socket needs always is open shape, stayed unsafe factor like this, for example, naughty child is because of curiosity, metal object inserted in the charged socket aperture can be caused the electric shock casualty accident; The exposed long-term incrustation of jack can reduce the insulation property of socket, also accelerates the oxidation of electrode in the socket aperture simultaneously and influences conductivity.

The purpose of this utility model is exactly at above-mentioned deficiency, and the existing power supply socket is improved, and provides a kind of preventing to get an electric shock, and guarantees the safety socket of socket secure conduction.

Technical solution of the present utility model is to keep the basic structure of existing socket, outer cover, pedestal, electrode, it is characterized in that, an active clapboard is housed between electrode and outer cover, the socket aperture that cooperates with outer cover or base is arranged on the dividing plate, between dividing plate and outer cover, elastic is housed.Its operation principle is, when socket does not use, because the effect of elastic, jack on the dividing plate and relative dislocation of jack on the outer cover make the socket aperture on the outer cover be sealed by dividing plate, when using this socket, plug is overcoming the active force that is contained in the elastic between dividing plate and the outer cover under the effect of applied force, make dividing plate and outer cover generation relative motion, and jack on the dividing plate and the socket aperture on the outer cover coincide, plug connects with the electrode that is contained on the pedestal immediately, and power supply is switched on.When cutting off the electricity supply, when pulling up plug, because the effect of elastic, relative motion takes place in dividing plate and outer cover once more, and the socket aperture on the outer cover is closed.

Advantage of the present utility model is; safe and reliable; can prevent that dust incrustation from polluting the destruction of causing the socket insulation property; avoid again because of artificial accidentally; the electric shock accidents that metal object is inserted charged socket aperture and cause; guard electrode alleviates its degree of oxidation simultaneously, thereby guarantees its excellent conducting performance.The required part of the utility model is few, and cost is low, easily promotes, and it can be widely used under the poor situation of environmental condition, as big places of oil smoke steam such as kitchen, bathrooms, promptly is suitable for safety again.

Below, embodiments of the invention are described with reference to the accompanying drawings:

As Fig. 1, shown in Figure 2, the utility model is by outer cover 1, shell fragment 2, support 3, base 4, electrode 5, active clapboard 6, screw 7 and screw 10 are formed, electrode 5 is fixed on the base 4 by screw 7, support 3 is on base 4, support 3 constitutes pedestal with base 4, have on the active clapboard 6 with outer cover 1 on the jack 11 that matches of socket aperture 8, the upper shed cross section of jack 11 is slope shape (just inserting with plug) on one side, active clapboard 6, shell fragment 2 is contained on the support 3, between outer cover 1 and the electrode 5, outer cover 1 is fixed on by screw 10 on the base 4 of pedestal, and screw 10 passes the pilot hole 9 in the middle of the active clapboard 6.

Fig. 3, Fig. 4, Fig. 5 are that another kind can be contained in the embodiment of the present utility model on the wall.It is by outer cover 1, base 4, electrode 5, active clapboard 6, spring 23, alignment pin 21, spiral arm 22, steady pin 19, bottom 15, fixed mount 13 and

screw

14,17,18 form, active clapboard 6 is embedded between outer cover 1 and the base 4, electrode 5 is contained in 4 li of bases, bottom 15 is contained in base 4 times, bottom 15 constitutes pedestal with base 4, pedestal is fixed on outer cover 1 back side by fixed mount 13 by screw 14, screw 17 makes substrate link to each other with fixed mount 15, screw 18 makes portable plate 6 be connected with base 4, the through hole 16 that matches with jack 11 on the active clapboard 6 is arranged on the base 4, one end of spring 23 is connected with active clapboard 6 by spiral arm 22, the other end of spring 23 is fixed on the steady pin 19 at outer cover 1 back side, the alignment pin 21 of restraint dividing plate 6 movement angles also is housed at outer cover 1 back side, terminals 20 are housed on base 4, terminals 20 communicate with corresponding electrode 5 separately, and fixing hole 12 is arranged on the outer cover.Use this embodiment product of the present utility model, as long as plug is inserted in the hole 11 on the active clapboard 6, rotary connector drives active clapboard 6, overcome angle of relative outer cover 1 motion of pulling force of spring 23, such as 60 °, making that the through hole 16 on jack 11 and the base 4 matches, plug is promptly connected with electrode 5, finish the energized process, when pulling the plug out of the socket, spring 23 will make active clapboard 6 recover returns, make jack 11 with hole 16 dislocation, the electrode 5 of socket is covered, not only safety but also insurance.
