Description
Technical field
The utility model relate in the electrical equipment plug assembly field a kind of induction safety socket.
Background technology
Monomer or platoon supply socket be our daily life and produce in electrical equipment grafting device commonly used, in the use since the attaching plug of plug electrical appliance accidentally or socket damage and the electric shock phenomenon often occurs, after particularly children touch socket, its finger is easy to touch the metal insert in the socket, causes personal injury or the accident that shocked by electricity happens occasionally.Present socket has only the fuse of setting usually, and this socket that installs fuse additional can only the excessive protection of brownout device electric current, and the electric shock phenomenon is not had protective effect.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of can be during near socket at staff, the internal electric source of automatic disconnection socket, and staff can recover the induction safety socket that the socket internal electric source connects after leaving automatically.
Its technical scheme is: comprise power line and socket, power line incoming end in socket is provided with the inductive control circuit that following circuit unit connects to form, and forms power supply circuits by shunt capacitance C1 and voltage stabilizing didoe DW behind the bridge rectifier of transformer B connection diode D1, D2, D3 and D4; Form body induction circuit by field effect transistor T connection resistance R 1, capacitor C 2, potentiometer W to the computing ic chip; Diode D5, resistance R 2 connect capacitor C 3, triode BG forms drive circuit; Relay J and its double-contact J1-1 form control circuit.Parallel diode D6 on relay J.
The utility model passes through human body induction control socket electriferous state, thereby human body especially children is played good safety precaution effect.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.CT is the 220V power supply among the figure; CZ is a socket.
Embodiment
Be further described with regard to its structure and operation principle below in conjunction with accompanying drawing:
Shunt capacitance C1, voltage stabilizing didoe DW form power supply circuits behind the bridge rectifier that transformer B connection diode D1, D2, D3 and D4 form; Field effect transistor T connects resistance R 1, capacitor C 2, potentiometer W and computing ic chip and forms body induction circuit; Diode D5, resistance R 2, capacitor C 3, triode BG form drive circuit; Relay J and its contact J1-1 form control circuit.The contact J1-1 of relay J is connected between power supply and the socket.Above-mentioned inductive control circuit is arranged in the socket, and is connected between the power line and metal insert of socket.
Operation principle: under the normal condition, field effect transistor T is in zero bias condition, and the resistance between its D, the S is less, and the current potential of the in-phase input end V+ of the computing ic chip that links to each other with D is also lower.The current potential of inverting input V-is transferred to a little higher than V+ with potentiometer W, V+＜V-like this, the output end vo of IC=0, triode BG by, relay J is failure to actuate.Because the contact J1-1 of relay J is in normally off, therefore, power supply is connected to socket through J1-1, and socket has.When human body during near socket, the grid G of field effect transistor T will be sensed the signal of telecommunication of human body, and the resistance between its D, the S increases like this, makes V+〉V-, the output end vo of IC=1, the BG conducting, relay J is adhesive immediately, and normally-closed contact J1-1 disconnects, the socket dead electricity.After waiting to finish the plug supply socket like this or leaving socket, automatic recovery of power supply enters normal mode.
Claims (2)
1, a kind of induction safety socket circuit, comprise power line and socket, it is characterized in that the power line incoming end in socket is provided with the inductive control circuit that following circuit unit connects to form, form power supply circuits by shunt capacitance C1 and voltage stabilizing didoe DW behind the bridge rectifier of transformer B connection diode D1, D2, D3 and D4; Form body induction circuit by field effect transistor T connection resistance R 1, capacitor C 2, potentiometer W to the computing ic chip; Diode D5, resistance R 2 connect capacitor C 3, triode BG forms drive circuit; Relay J and its double-contact J1-1 form control circuit.
2, induction safety socket circuit according to claim 2 is characterized in that: parallel diode D6 on relay J.
