Description
Technical field
This utility model relates to a kind of power circuit, specifically a kind of energy saving power socket control circuit.
Background technology
Along with improving constantly of people's living standard, electronic equipment has become as a requisite part in life, especially
Various household electrical appliance bring great convenience to the life of people, work, and this kind of electronic installation has been desirable that a precision relatively
The constant voltage dc source high, electric current is bigger.The constant voltage dc source of existing market is of a great variety, and its mid and low-end products are the most,
Although low-end product has the advantage of price relative to high-end product, but quality is the most as one wishes, and common regulated power supply is equal
There is the defects such as function singleness, the life-span is short, quiescent dissipation is high, although and high-end product reliable in quality, safety and stability, but
Price is high also allows people hang back.Therefore need to be improved.
Utility model content
The purpose of this utility model is to provide a kind of energy saving power socket control circuit, to solve to propose in above-mentioned background technology
Problem.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of energy saving power socket control circuit, including resistance R1, voltmeter V, relay K and chip IC 1, described electricity
One end of resistance R1 connects electric capacity C1, power supply VCC and the pin 3 of chip IC 1, and the other end of resistance R1 connects diode D1
Anode, the negative electrode of diode D1 connects the contact K-1 of relay K and relay K ground connection, the other end of electric capacity C1
Connect electric capacity C2, electric capacity C3, the negative electrode of diode D2, voltmeter V, the other end of contact K-1 of relay K, electricity
The fixing end in one of device RP1, position and the sliding end of potentiometer RP1, another fixing end of potentiometer RP1 connect resistance R2,
The other end of electric capacity C2 and the pin 1 of chip IC 1, the pin 2 of chip IC 1 connect the other end of resistance R2, resistance R4,
The other end of electric capacity C3, the other end of voltmeter V and socket A, the other end of socket A connects the other end of relay K,
The other end of resistance R4 connects the anode of diode D2, and the model of described chip IC 1 is LM317.
As preferred version of the present utility model: described diode D1 and diode D2 is light emitting diode.
Compared with prior art, the beneficial effects of the utility model are: this utility model energy saving power socket control circuit structure
Simply, components and parts few, stablize adjustable DC voltage can not only to load offer, and circuit is several when not accessing load
Not power consumption, quiescent dissipation is the lowest, therefore has diverse in function, length in service life and the advantage of saves energy.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of energy saving power socket control circuit.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of energy saving power socket control circuit, including resistance R1, voltmeter V, relay K and chip
One end of IC1, described resistance R1 connects electric capacity C1, power supply VCC and the pin 3 of chip IC 1, the other end of resistance R1
Connect the anode of diode D1, the contact K-1 of the negative electrode connection relay K of diode D1 and relay K ground connection, electricity
The other end holding C1 connects electric capacity C2, electric capacity C3, the negative electrode of diode D2, voltmeter V, the contact K-1 of relay K
The other end, one of potentiometer RP1 fixing end and the sliding end of potentiometer RP1, another fixing end of potentiometer RP1
Connecting resistance R2, the other end of electric capacity C2 and the pin 1 of chip IC 1, the pin 2 of chip IC 1 connects the another of resistance R2
One end, resistance R4, the other end of electric capacity C3, the other end of voltmeter V and socket A, the other end connection of socket A continues
The other end of electrical equipment K, the other end of resistance R4 connects the anode of diode D2, and the model of described chip IC 1 is LM317.
Diode D1 and diode D2 is light emitting diode.
Operation principle of the present utility model is: the voltage of power supply VCC is added in input 3 foot of voltage stabilizing chip IC 1, its output
Hold 2 foot output galvanic current pressures, adjust the resistance of RP, VD can be made to regulate within the specific limits, flat
Time when not using load, be not turned on inside socket A, therefore relay K is not turned on, and its normally opened contact K-1 disconnects, whole
Circuit does not works, and only light emitting diode D1 lights work as power supply indicator, and therefore its quiescent dissipation is the lowest, makes
Used time, load accessing the internal conducting of socket A, socket A, relay K turns on, the K-1 adhesive of its contact, therefore circuit
Electric, light emitting diode D2 lights, and voltmeter V obtains electric simultaneously, can demonstrate the supply voltage feelings of load intuitively
Condition, when not using load, pulls up plug, and socket A disconnects again, thus recovers low-power consumption standby state.
