Abstract
The plug and socket with permanent magnet and dry reed pipe and bidirectional SCR are installed inside the socket. Therefore, the socket is not electrified when not used, and the circuit can be conducted only when the plug is completely inserted into the socket, so that the safety and no spark are generated, and electric shock and fire can be prevented.
Description
The utility model relates to a kind of electrical equipment plug-in unit class of protection against electric shock.
At present, in people's daily life, normally used plugs and sockets because plug one inserts socket, has promptly been connected power supply, and the electric shock phenomenon takes place easily, also is easy to generate electric spark, causes fire, makes people feel to use and lacks the sense of security.
The purpose of this utility model is to be to overcome above-mentioned deficiency, provides a kind of, and the technical scheme with magnetic patch connection electronic component turning circuit can solve the generation of electric spark when using switch and the problem of protection against electric shock.
The utility model is achieved in that integrated circuit (Fig. 1) is placed on wiring board (5) goes up (see figure 2), then wiring board (5) and socket panel (1) is fixed together, and has formed a new socket.The installation (see figure 1) of wiring board is installed a connection tongue tube (3) and bidirectional triode thyristor (4) on former socket circuit, connect by R simultaneously
2C
2The bidirectional triode thyristor protective circuit of forming, R
1Be The Trigger of Bidirectional Triode Thyristor resistance, C
1Effect be when being perception as load, behind logical and outage source, can avoid producing self induction voltage, bidirectional triode thyristor is punctured, when the plug short circuit, the big electric current of generation can so just have been avoided Danger Electric shock risk to silicon controlled rectifier protecting danger fuse failure.When socket did not use, metal was not charged in it.
Plug is a permanent magnet (6) to be housed form in the middle of two inserted sheets of ordinary plug (7), and making the plane of permanent magnet and plug end face is same plane.
Again in conjunction with the embodiments, accompanying drawing is illustrated below.
Fig. 1 is circuit theory diagrams, and wherein (3) are that tongue tube, (4) are bidirectional triode thyristor.
(1) is that socket panel, (2) are plug slice for wiring board, (6) for permanent magnet, (7) for receptacle sockets, (5) among Fig. 2.
When using like this with plug slice (7), insert in the receptacle sockets (2), have only when inserted sheet all inserts in the jack, the permanent magnet on the plug (6) uses tongue tube (3) magnetization on the socket wiring board and closure, and then triggers bidirectional triode thyristor (4) turning circuit.At this moment power connection.The power supply of this plugs and sockets is contactless when conducting or disconnection.So can not produce spark when using no switch load household electrical appliances, the fire that can avoid like this causing because of switch load break-make pyrophoric behavio(u)r is suffered from, it more adapts to the place use that does not allow pyrophoric behavio(u)r.This also is very safe owing to have only whole the coincideing of plug and socket just can switch on simultaneously.
Claims (1)
1, a kind of protection against electric shock no-spark plugs and sockets of forming by plug, socket and electronic component, it is characterized in that implanting a permanent magnet (6) in the intermediate surface of two inserted sheets (7) by described plug, to make permanent magnet and plug end face be same plane, described socket is to connect a wiring board (5) in its panel (1) back with sieve silk, tongue tube (3) is being housed on the switching circuit and bidirectional triode thyristor (4) is connected by R on circuit
2C
2The bidirectional triode thyristor protective circuit and the R that form
1Trigger resistance and C
1Electric capacity.
