Abstract

The utility model relates to a safety power-supply socket. The utility model which is designed for solving the arrangement of the light switch of the existing socket, which is difficult to prevent the electric shock accident, comprising a socket base, a base cover, and a socket element. A column, pressing button, a spring, an end piece, and a copper piece are arranged in the socket base. The end piece and the copper piece are contacted by making use of the plug which is reliably inserted into the socket to connect with the plug power supply. The power supply is connected when the plug is reliably inserted in the socket because of the design of the utility model, and the plug is drawn out or the socket contract is unreliable, the power supply is unconnected. The utility model is suitable for using in the unit, the household and various occasions.

Description

Safety socket

The utility model relates to the Electrical Safety socket.

The current commercially available and employed supply socket of people, having some is the socket with switch that prevents that electric shock accidents from taking place to design.Its structure has normally been set up switch in the structure of common socket, power line is connected socket again through switch.The switch of this socket is significantly, and is very easy to start.Like this, the strick precaution effect is just very unreliable.

The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of switch that is provided with hidden is provided, and must insert the power safety socket that plug could be connected switch.

The task that the utility model proposed is finished by following technical proposals: a kind of safety socket, comprise socket base, socket flap and socket piece, in socket base, from top to down is provided with cylinder, press button and spring, on socket base, be equipped with drop-center corresponding to press button, on drop-center, the other dististyle that is provided with contact-carrying of press button, in the socket piece outside, establish a copper sheet corresponding to the dististyle contact, the socket flap is provided with perforate, and the perforate that the cylinder that is connected as a single entity with press button passes on the flap exceeds the flap horizontal plane.

The purpose of the utility model also can realize by following technical proposals: a kind of safety socket, comprise socket base, socket flap and socket piece, and in socket base, from top to down is provided with cylinder, press button and spring.The press button outside is provided with barrier flaps, and at the other dististyle that a L type contact-carrying is set of press button, this dististyle other end is fixedlyed connected with socket piece.In socket base, be provided with the copper sheet of contact-carrying corresponding to L type dististyle contact position.Barrier flaps on the press button is between dististyle and copper sheet.The socket flap is provided with perforate, and the perforate that the cylinder that is connected as a single entity with press button passes on the flap exceeds the flap horizontal plane.

The task that the utility model proposed is further finished by following technical proposals: the tapered or cylindricality of described press button, and the lower end inner chamber of press button has the groove of device spring, and the natural length of spring is greater than depth of groove.

The utility model, and utilizes plug reliably to insert socket and can connect switch socket, switch integrator textural, makes two pins of plug obtain power supply.In case plug is extracted, outage immediately can prevent that the child from stretching in the socket with hand carelessly and get an electric shock.In case the press button switch is depressed because of curious by the child, also must both hands insert simultaneously in the socket and just can get an electric shock.This situation is extremely difficult to be taken place.Just in case take place, the child must be drawn back one's hand by electric shock to unclamp at once.Spring in the safety socket is upspring immediately and is cut off the power supply, and being unlikely always, energising causes tragedy.In addition, when inserting owing to plug, must depress press button really, switch could be switched on, and can prevent that carelessness or drunken person from inserting carelessly with meeting accident.

Accompanying drawing provides two embodiment of the present utility model.

Fig. 2 is the structural representation of the safety socket user mode shown in the embodiment one.

Fig. 3 is the safety socket installation diagram shown in the embodiment one.

Fig. 4 is the structural representation of the utility model embodiment two.

Fig. 5 creates the position amplification stereogram for the utility model.

Below, the embodiment shown in is described in detail the utility model in conjunction with the accompanying drawings.

Embodiment one:

A kind of safety socket comprises socket base 1, socket flap 2 and socket piece 3.In the central authorities of base 1, from top to down is provided with cylinder 4, press button 5 and spring 6.It is conical that press button 5 is, and its lower end inner chamber has groove 7, and spring 6 is seated in the press button groove 7.The natural length of spring 6 is greater than the degree of depth of groove 7.Be equipped with perforate 8 on the socket flap 2.The cylinder 4 that is connected as a single entity with press button 5 passes the horizontal plane that perforate 8 on the flap exceeds flap 2.For preventing spring displacement distortion, in base 1, be provided with a drop-center 9.On drop-center 9, press button 5 sides are provided with dististyle 10, and this dististyle 10 is provided with contact 15.In the outside of socket piece 3, be provided with a copper sheet 11 corresponding to the contact position of dististyle 9.Contact on the dististyle 10 is corresponding with copper sheet 11.In plug insertion socket, when two pins 13 of plug inserted socket piece 3, the cylinder 4 that safety socket central authorities protrude was depressed.It drives press button 5 compression springs 6, and the press button sidewall conical surface forces dististyle 10 outward-dipping.And the insertion of pin 13 is outwards heaved concave shaped socket spare 3 two ends, and this just makes the contact of dististyle 10 reliably contact with socket piece 3 walls copper sheet 11 outward.One is connected with another socket piece 3 in two power lines, and another root is connected with dististyle 10.Dististyle 10 gets with two pins 13 that make plug being connected of 11 of copper sheets.Otherwise, pulling the plug out of the socket the not time spent, taper press button 5 is upspring by the elastic force of its groove 7 inner springs 6, the disengaging that resets of dististyle 10 and copper sheet 11, thereby open circuit.

Embodiment two:

Safety socket shown in this example comprises socket base 1, socket flap 2 and socket piece 3.From top to down is provided with cylinder 4, press button 5 and spring 6 in base 1.Press button is cylindrical, and its lower end inner chamber has groove 7, and spring 6 is loaded in the groove 7.The outside of press button 5 is provided with a barrier flaps 14, and the natural length of spring 6 is greater than the degree of depth of groove.Be provided with L type dististyle 10 in the base 1, an end of dististyle 10 is provided with contact 15, and dististyle 10 is fixedlyed connected with socket piece 3 by nail.L type dististyle 10 sides are provided with I type copper sheet 11, and these copper sheet 11 1 ends are fixed on the base 1.Two contacts 15 of L type dististyle and I type copper sheet 11 contact.When not inserting plug, because spring 6 supporting roles make press button 5 unsettled, barrier flaps 14 between two contacts, is separated dististyle 10 and copper sheet 11 just.One is connected with socket piece 3 ' in two power supplys, and another root is connected with copper sheet 11.When plug 12 inserts socket, when cylinder 4 is depressed, drives press button 5 and move down, the barrier flaps 14 on the press button 5 also moves down thereupon and breaks away from dististyle 10 and copper sheet 11.11 liang of contacts of dististyle 10 and copper sheet contact, and make power connection.Pull the plug out of the socket 12, spring 6 is upspring, and moves on the press button 5, drives barrier flaps 14 and also up moves between dististyle 10 and the copper sheet 11 the two isolation, and power supply disconnects.
