Abstract

The utility model relates to a power switch socket, particularly a switch socket which can carry out timing control. The switch socket mainly comprises a casing, an externally connected power cord, a socket position, a control button, a time status indicating lamp, a power indicating lamp and a timing device, wherein, the timing device can control the actions of the socket position, the control button, the time status indicating lamp and the power indicating lamp; the timing device is composed of a transformer, a rectifier, a filter, a voltage stabilizing power, a voltage stabilizing element and an integrated circuit having a timing function. The utility model has the advantages of simple structure, reliable timing, safety and high durability.

Description

The timing control switch socket

Technical field

The present invention relates to a kind of mains switch socket, especially a kind ofly carry out time-controlled combined socket and switch.

Background technology

What present appliance switch socket generally adopted is the plain edition combined socket and switch that does not have timing function; generally form by socket box, socket position and jack contact etc.; part band control switch is wherein arranged; during use plug injected and get final product energized in the jack; in the time of need cutting off the electricity supply; dial plug or disconnect the pass and get final product; but things such as outage usually can appear in the daily use forgetting; make electrical equipment switch on for a long time; cause waste; simultaneously, the long-time in running order meeting of electrical equipment causes the aging even damage electrical equipment of heating of electrical equipment.

Summary of the invention

The purpose of this utility model is to avoid the weak point in the above-mentioned background technology and a kind of timing control switch socket that can regularly open and close is provided.The major part of this timing control switch socket is shell, circumscripted power line, socket position, control button, time state indicator light and power supply indicator and timing device, timing device can be controlled the action of socket position, control button, time state indicator light and power supply indicator, timing device is made up of transformer, rectifier, filter, stabilized voltage power supply, voltage stabilizing element and integrated circuit with clocking capability, the timing pulse signal that integrated circuit sent, control relay work after amplifier amplifies, thereby the keying of control socket position.The utlity model has following beneficial effect: simple in structure, regularly reliable, safety durable.

Embodiment

Below in conjunction with drawings and Examples essentiality content of the present invention is described in further detail.

Shown in the adjoint, this timing control switch socket major part is a shell 1, circumscripted power line 2, socket position 3, control button 4, time state indicator light 5 and power supply indicator 6 and timing device 7, timing device 7 can be controlled socket position 3, control button 4, the action of time state indicator light 5 and power supply indicator 6, timing device 7 is by transformer, rectifier, filter, stabilized voltage power supply, voltage stabilizing element and integrated circuit composition with clocking capability, the timing pulse signal that integrated circuit sent, control relay work after amplifier amplifies, thereby the keying of control socket position 3.AN is provided with switch, IC fast ₂Advance timer, J as ten ₀Be the time relay, (A, the output of B point control signal), firm power-on, IC ₂The external differential circuit C of pin ₃Capacitor and R ₃Resistance generation saltus step pulse automatically resets it and is high level Q ₀Then press AN regularly, during AN switch UNICOM, IC ₁Be about 1s with the cycle and vibrate, make IC ₂Step-by-step counting till the LED of required timing correspondence is luminous, regularly begins.After this, IC ₂Cycle of oscillation is by resistance R ₂And capacitor C ₂Parameter is carried out (about 10min), regularly ends at IC ₂Count status is got back to Q ₀Be high level, J ₀Signal work is arranged.Regularly length is with IC ₁Cycle of oscillation, 10min calculated, and was set to Q ₁, the luminous timing length of corresponding LED is 90min, is set to Q ₂, the luminous timing length of corresponding LED is 80min, the rest may be inferred, and Q is set ₉The corresponding luminous timing length of LED is 10min.The regularly change of stepped intervals can be by changing IC ₁Vibration Resistor-Capacitor Unit R ₂And C ₂Value realizes.In real-time way if power interruptions, R are arranged ₄Make IC after interrupting recovering ₂Automatically reset Q ₀Be high level, J ₀Work.
