Abstract

The utility model relates to an automatic power-off power socket. The automatic power-off power socket is composed of a common plug board circuit and a self-power-off button switch. The self-power-off button switch is formed by modifying an electromagnetic coil on the basis of a common plug board button switch, and specifically comprises an iron core button, an electromagnetic coil, a reset spring, a plastic button cap, a moving contact sheet and fixed contact points. The automatic power-off power socket is characterized in that when equipment is powered on, the electromagnetic coil attracts the iron core button to go downwards, and a connected-circuit state of a power supply is not changed; and when the equipment is powered off, the attraction of the electromagnetic coil disappears, the iron core button springs up under the action of the reset spring, and the power socket becomes to be in an open-circuit state. The automatic power-off power socket, through the effects of attraction and release of the iron core button through the electromagnetic coil, simulates processes of manually pressing down and releasing the button, realizes an automatic power-off function of the power socket, and achieves an aim of energy saving and emission reduction while improving the security of using the equipment, and thus is of good practical value.

Description

A kind of auto-breaking supply socket

Technical field

The utility model relates to a kind of supply socket, particularly a kind of supply socket with automatic circuit break function.

Background technology

When using television set in family at present, can be connected with simultaneously television set, cable TV set-top box in general supply socket.When office and family's use computer, can be connected with simultaneously host computer, display, sound equipment, printer, router etc. in supply socket.When people finish watching TV the late into the night, when remote controller closing television machine was arranged, set-top box and television set in fact still were in little power consumption state of energising.When people use computer, when Shutdown Hosts leaves, often forget the power supply of peripheral hardwares such as closing sound equipment, printer.If things go on like this, not only wasted electric energy, reduced service life of equipment, more may cause equipment heating, initiation fire causes unnecessary tragedy.

For the problems referred to above, a kind of auto-breaking supply socket of the utility model design.When needs use the computer or television machine, press the supply socket button, make socket be in "on" position, then open the computer or television electromechanical source, use.When use finishing, when computer or television office closed, electric socket can automatic disconnection, and computer peripheral equipment or television set, set-top box power supply all can disconnect like this, thereby have greatly improved the equipment safety in utilization.

Summary of the invention

For the problem of present existence, the purpose of this utility model is to provide a kind of simple in structure, with low cost, convenient and practical auto-breaking supply socket, to solve family or office equipment potential safety hazard in use, saves simultaneously electric energy.

For achieving the above object, the utility model adopts following technical proposals: a kind of auto-breaking supply socket, it is comprised of common plate circuit and Self-disconnecting push-button switch, it is characterized in that: described Self-disconnecting push-button switch is that the repacking solenoid forms on common plate push-button switch basis.When using computer, first press the lower plugboard push-button switch, plate is in "on" position, can use computer and other peripheral hardware.When using computer or peripheral hardware equipment, there is operating current to pass through in plate, this moment,, there was strong sucking action in solenoid work to shift knob, and shift knob is downward, is equivalent to simulate manual push.At this moment, whole plate circuit still is in conducting state.Finish when electrical equipment uses, after shutdown, only have atomic weak current to pass through in the plate circuit, solenoid is removed the attraction of button, and shift knob is got back to initial open position under the effect of back-moving spring, be equivalent to the operation that the artificial hand unclamps.At this moment, the plate outage, thus realized automatic circuit break function.

Compared with prior art, the utlity model has following significant advantage is:

1) utilize the electromagnetic relay power on/off, the operation with the release button switch is manually pressed in simulation, easily realizes the plate automatic circuit break function.

2) circuit is simple, does not need complicated circuit design and a large amount of electronic devices and components.

3) opening of device formula, electric socket keeps conducting, and during the equipment shutdown, the electric socket auto-breaking has energy-saving and cost-reducing function, has effectively extended the useful life of electrical equipment simultaneously.

Fig. 2 is Self-disconnecting push-button switch closed-circuit working schematic diagram;

Fig. 3 is the manual down state schematic diagram of Self-disconnecting push-button switch simulation.

Embodiment

Below in conjunction with accompanying drawing, by embodiment, technical solutions of the utility model are described further.

This utility model auto-breaking supply socket is comprised of common plate circuit and white cut-off button switch.The Self-disconnecting push-button switch is that the repacking solenoid forms, and is specially: iron core button 1, solenoid 2, back-moving spring 3, plastic button cap 4, mobile contact 5, fixed contact 6 on common plate push-button switch basis.

During device powers down, the push-button switch structure of electric socket as shown in Figure 1.When needs use equipment, press power switch button, mobile contact 5 contacts with fixed contact 6, and power supply is switched on this moment, as shown in Figure 2.Next, can use the various device that is connected with electric socket.When TV, apparatus such as computer normal operation, the solenoid energising, iron core button 1 is attracted downwards, is equivalent to simulate manual push, as shown in Figure 3.When the equipment such as computer, TV use the end shutdown, the interior current strength of solenoid 2 has minimizing, iron core button 1 pops up under the effect of back-moving spring, be equivalent to the operation of artificial hand's release button, mobile contact 5 is upspring simultaneously, power supply disconnects, and this moment, the push-button switch of electric socket was got back to again structure shown in Figure 1.

Claims

1. auto-breaking supply socket, formed by common plate circuit and Self-disconnecting push-button switch, it is characterized in that: the Self-disconnecting push-button switch is on common plate push-button switch basis, the repacking solenoid forms, and mainly comprises iron core button (1), solenoid (2), back-moving spring (3), plastic button cap (4), mobile contact (5) and fixed contact (6).

2. a kind of auto-breaking supply socket as claimed in claim 1 is characterized in that: during the equipment energising, solenoid (2) attracts iron core button (1) downward, does not change the channel status of power supply; During the equipment shutdown, the attraction of solenoid (2) disappears, and iron core button (1) is upspring under the effect of back-moving spring (3), and electric socket becomes off state.
