The timing socket comprises a power plug, a power cord, a shell, a power output jack, a circuit board and an output indicator light, the surface of the shell is provided with a timing dial, a timing adjustment knob and a timing pointer, the timing dial is matched with the timing adjustment knob and the timing pointer, and the timing adjustment knob is matched with a potentiometer on the circuit board; the circuit board is composed of a power supply circuit, a timing control circuit and an electronic switching circuit, the ganged switch of the potentiometer controls the power supply of the timing circuit, and the two ends of the appliance socket are connected with an output indicating circuit composed of a light-emitting diode and a resistor in parallel. The timing socket has the advantages that the structure is simple, the assembly is convenient, the timing socket which can be arranged in front of the required appliance power supply can play the role of cutting off the power supply circuit at a predetermined time, and the purposes of security and energy-saving can be achieved.

Description

The timing socket

Technical field

The utility model relates to a kind of timing socket of electrical equipment automation field.

Background technology

Many electrical equipment of present family or office be mostly by supply socket transfer the power supply, sometimes only need work a period of time, and concerning the people in busy and usually forget, cause danger so sometimes, can dwindle useful life greatly electrical equipment sometimes, electric power energy is caused waste.

Summary of the invention

The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of timing to disconnect the timing socket of power supply circuit.

Its technical scheme is: comprise attaching plug 1, power line 2, shell 3, power supply output plughole 7, circuit board 8 and output indicator 10, case surface is provided with regularly dial 4 and cooperates with regularly adjusting knob 6, timing pointer 5, and timing adjusting knob 6 cooperates with potentiometer W on the circuit board 8; Described circuit board is connected to form by following circuit: form power supply circuits by connection diode D1, voltage stabilizing didoe DW and capacitor C 2 behind the capacitor C 1 parallel resistance R1, form timing control circuit by time-base circuit IC connection resistance R 5, potentiometer W, capacitor C 3, C4, diode D3, relay J, form electronic switching circuit by triode Q1 connection triode Q2, Q3, resistance R 2, R3, R4, the power supply of the linked switch K2 control timing circuit of potentiometer W, the output indicating circuit that the parallel connection of appliance socket two ends is made up of LED and resistance R 6.Battery main switch 9 is set, at relay J two ends parallel diode D2 on shell.

The utlity model has simple in structure, install additional conveniently, be installed in the appliances power source that needs before, can play a part regularly to disconnect power supply circuit, play safety, energy-conservation target.

Description of drawings

Accompanying drawing 1 is the external structure of a kind of embodiment.Accompanying drawing 2 is circuit theory diagrams of a kind of embodiment.CZ is electrical appliance socket (7 among Fig. 1) among Fig. 2; CT is attaching plug (1 among Fig. 1);

Embodiment

Be further described with regard to its structure and operation principle below in conjunction with accompanying drawing:

Among Fig. 1: form by attaching plug 1, power line 2, shell 3, timing dial 4, timing adjusting knob 6, timing pointer 5, power supply output plughole 7, circuit board 8, battery main switch 9, output indicator 10; Circuit board section is seen Fig. 2.Regularly adjusting knob 6 is the adjusting knob of potentiometer W among Fig. 2, and linked switch K2; Attaching plug 1 is the CT among Fig. 2; Power supply output plughole 7 is the CZ among Fig. 2; Battery main switch 9 is the K1 among Fig. 2; Output indicator 10 is the LED among Fig. 2.

Among Fig. 2: form power supply circuits by capacitor C 1 parallel resistance R1 connection diode D1, voltage stabilizing didoe DW and capacitor C 2; Form timing control circuit, relay J two ends parallel diode D2 by time-base circuit IC (NE555) connection resistance R 5, potentiometer W, capacitor C 3, C4, diode D3, relay J; Form electronic switching circuit by triode Q1 connection triode Q2, Q3, resistance R 2, R3, R4; The power supply of the linked switch K2 control timing circuit of potentiometer W; The output indicating circuit that the parallel connection of appliance socket two ends is made up of LED and resistance R 6.

Operation principle: when not needing regularly, K switch 2 is closed attaching plug CT insertion power supply and rotational potentiometer W, open total power switch K1.At this moment, owing to K switch 2 is closed, so timing control circuit can not get power supply and do not work.Simultaneously, power supply is through resistance R 2 trigger triode Q2 conductings, Q3 conducting immediately, and the relay J adhesive, its contact J-1 closure, appliance socket CZ gets electric, and electrical work is not subjected to time-delay control.

When the needs timing controlled, after attaching plug CT inserted power supply and rotational potentiometer W and K switch 2 is opened and be threaded to required timing, open total power switch K1.At this moment, because K switch 2 is connected, timing control circuit obtains power supply and works.Power supply is through resistance R 4 trigger triode Q1 conductings, Q2, Q3 by, relay J is not controlled by electronic switching circuit.Simultaneously owing to form timing control circuit and be operated in monostability by time-base circuit IC (NE555) connection resistance R 5, potentiometer W, capacitor C 3, C4, diode D3, relay J, initial its output high level makes the relay J adhesive through diode D3, its contact J-1 closure, appliance socket CZ gets electric work.Behind the certain hour, timing control circuit gets monostability to be finished, time-base circuit IC output low level, and diode D3 discharges by relay J, and its contact J-1 disconnects, and appliance socket CZ dead electricity quits work, and finishes regularly.
