Abstract

The utility model relates to a plug and a socket which are used for a small household appliance. The utility model adopts a decomposing magnetic circuit, and an induction current is obtained by a first and a secondary coils. The exposition of a copper sheet can be avoided by using the utility model, the safety performance is good, the electricity can not be touched, and the plug and the socket are especially suitable for youths and children. When the plug and the socket are used in the dark, the plug is easy to insert into the hole eyes of the socket, and blind men can also use the plug like normal persons. In addition, the utility model does not afraid water, and can also be used in wet places. The utility model has the advantages of simple structure and low cost, and is the preferred plug and the socket for the household appliance with low power.

Description

Induction plug and socket

The utility model relates to a kind of appliance plug socket, the plugs and sockets that particularly a kind of small household appliance uses.

At present, the appliance plug socket generally all adopts three or two, because copper sheet exposes, easily produces and gets an electric shock, especially juvenile, children use, and make its father and mother and household worried, in addition, and when in the dark, want plug insertion socket very difficultly, and easily go out danger, the blind person will plug in more difficult.Secondly, the ordinary plug socket just can not be installed and used in the environment of humidity, in the bathroom.

The purpose of this utility model will overcome above-mentioned defective exactly, designs a kind of brand-new plugs and sockets.

The technical solution of the utility model:

The feature of induction type socket is 220V AC power one termination tongue tube one end, another termination primary coil one end of tongue tube, and another termination of primary coil 220V AC power other end, primary coil is on the elementary iron core of " E " type.

The feature of induction type plug be secondary coil on the secondary iron core of " E " type, the elementary iron core of " E " type on secondary iron core of " E " type and the socket lumps together formation and " says " the sections core, and a permanent magnet is arranged on the plug, and is corresponding with the tongue tube on the socket.

Advantage of the present utility model and effect are not expose copper sheet, safety, be even more important for juvenile, children, the defective that need not seek eyelet and avoid the ordinary plug socket not insert, owing to be to respond to, be particularly suitable in wet environment, using, can prevent that also the guest from stealing electricity consumption even causing fire in hotel or hostel.

Embodiment 1:

Shown in Fig. 1 left side, 220V AC power and tongue tube 1, the primary coil 2 on the elementary iron core 4 of " E " type constitute a loop on the socket, because tongue tube 1 be not subjected under the magneticaction, all the time disconnect, flow through with regard to no current in the primary coil 2, elementary iron core 4 internal magnetic circuits of " E " type are obstructed.

Shown in Fig. 1 right-hand part, the secondary iron core 6 of " E " type is arranged on the plug, the secondary iron core of " E " type 6 is corresponding with the elementary iron core of " E " type 4 fully, lump together formation and " say " the sections core, be wound with secondary coil 5 on the secondary iron core 6,5 liang of output of secondary coil termination current rectifying and wave filtering circuit 8, on plug, also has a permanent magnet 7, corresponding with the tongue tube 1 on the socket, permanent magnet 7 one ends are fixedlyed connected with feeler lever 9 one ends, feeler lever 9 other ends expose plug one side a little, spring 10 is enclosed within on the feeler lever 9, one end withstands on the jacking block 11, and the other end is fixed on the feeler lever 9, and jacking block 11 is fixed on the plug.

During use, as shown in Figure 2, socket (left side), plug (right side) lump together by the dotted line direction, as shown in Figure 1, when socket, plug near the time, pinning feeler lever 9 with hand also pushes inwards, make permanent magnet 7 to dotted line position, the tongue tube 1 of permanent magnet 7 on can not alignment socket like this, tongue tube 1 still disconnects, and the secondary iron core 6 of " E " type on elementary iron core 4 of " E " type on the socket and the plug is combined into one " saying " sections core fully, forms complete magnetic circuit.When unclamping feeler lever 9, spring 10 makes permanent magnet 7 be returned to original position.This position just in time with socket on tongue tube 1 fully over against, and make tongue tube 1 closure, primary coil 2 is by electric current, " saying " sections in-core produces magnetic flux, makes the secondary coil 5 on the plug induce electric current, output voltage is through current rectifying and wave filtering circuit 8 output DCs.In order to be unlikely when having a power failure suddenly, " say " the sections in-core and do not have magnetic flux, and cause plug and socket (fixing usually on the wall) to separate and fall down, buckle 12 of design on plug, corresponding draw-in groove 13 of design on socket, buckle 12 is stuck in 13 li of draw-in grooves like this, and plug just can not fall down.

Because the electric current that secondary coil 5 induces on the plug is less, generally only being applicable to needs the galvanic small electric apparatus of a few volt to tens volts, so use the utility model in hotel, hostel, the tenant just can't come to power supplies such as electric furnace, hair dryers with it.

Certainly, according to the utility model principle, do greatly as iron core, its secondary coil power output is corresponding also big.

Reliable more fully when the utility model is used, can on plug, socket relevant position, mix two tongue tubes, two permanent magnets.In case can avoid like this tongue tube on the socket not with plug on permanent magnet have an effect, thereby and be subjected to other magnetic bodies and phenomenon that fuse is burnt in short circuit that adhesive caused.

Claims

1, induction type socket is characterized in that 220V AC power cord one termination tongue tube 1 one ends, tongue tube 1 another termination primary coil 2 one ends, and primary coil 2 another termination 220V AC power cord other ends, primary coil 2 is on the elementary iron core 4 of " E " type.

2, induction type plug, it is characterized in that secondary coil 5 is on the secondary iron core 6 of " E " type, the elementary iron core 4 of " E " type on secondary iron core 6 of " E " type and the socket lumps together formation and " says " the sections core, and a permanent magnet 7 is arranged on the plug, and is corresponding with the tongue tube 1 on the socket.

3, induction type plug according to claim 2 is characterized in that secondary coil 5 output termination current rectifying and wave filtering circuits 8.
