Abstract

A self-locking power socket for power failure. When the power supply is cut off, the power switch of the electric appliance is not needed to be turned off, the power socket is automatically locked in a cut-off state, and when the power supply is powered on again, the electric appliance cannot be electrified. The main function of the automatic device is to automatically cut off the power phase line of the socket after the power supply is cut off, so that the socket can not output power. The main purpose is to avoid electric energy waste, equipment aging, shortened service life, equipment burnout, fire or other accidents caused by the automatic working state of the electric appliances.

Description

Power failure self-locking supply socket

The utility model relates to a kind of supply socket, especially a kind of supply socket of the self-locking that can have a power failure.

At present, known supply socket, after power failure, can not automatically be locked in dissengaged positions, when sending a telegram here once more, supply voltage may be too high or with the surge voltage of higher amplitude, if forgotten the mains switch of turning off consuming device after power failure, then consuming device will automatically enter operating state, and the waste of energy that causes therefrom, personal electric shock phenomenon, device damage, fire incident are of common occurrence.

In order to overcome existing supply socket can not automatically be locked in dissengaged positions after power failure deficiency, the utility model provides a kind of supply socket, after power supply has a power failure, the mains switch that needn't turn off consuming device, supply socket just automatically is locked in dissengaged positions, when power supply is sent a telegram here once more, consuming device can be not charged, when consuming device is reworked, must press the start button in the supply socket once more, consuming device could charged again work.

The technical scheme that its technical problem that solves the utility model adopts is: its structure is to have increased by a cover automatics on the basis of existing supply socket again.Its circuit diagram as shown in Figure 2, when supply voltage just often, red light emitting diodes LED ₁Light, hand is pressed start button SB ₁, the normal opened contact of start button is connected, at this moment relay K ₁Obtain exciting current and move, make K ₁-1 contact is connected, and hand is decontroled start button SB ₁, because of relay K ₁Contact K ₁-1 self-sustaining and still keep excited state, this socket passes through XS ₁, XS ₂Power to consuming device.When power supply has a power failure suddenly, relay K ₁Make its contact K because of losing exciting current ₁-1 disconnects, when supply voltage recovers just often XS again ₁, XS ₂Still no-voltage just automatically is locked in dissengaged positions, wants to make consuming device to rework, and must press start button SB again ₁, consuming device could charged again work.When if consuming device is not temporarily worked, only need press stop button SB ₂, make the normally closed contact disconnection that stops to connect button, relay K ₁Make its contact K because of losing exciting current ₁-1 disconnects XS ₁, XS ₂Just temporarily stop power supply, not only convenient but also safety works together.

Shape of the present utility model can manufacture diversified pattern as shown in Figure 1, can cause concealedly, installs that shell and metope are flat on the wall; Can cause exposed type, the outstanding metope of shell on the wall is installed; Can cause portablely, power line is extended with three core rubber cables, can move from electromigration.In the power failure self-locking supply socket, one or more three jacks and one or more two receptacle electrical connectors are arranged, receptacle connector is contained in the bottom surface.In the element of automatics, electric power incoming line L, N, PE enter from the side of shell, protective tube, red light emitting diodes LED ₁, green LED LED ₂, start button SB ₁, stop button SB ₂On the shell of top loading, other elements all are contained on the shell of bottom surface.The connection of electricity is pressed Fig. 2 and is connected.

The beneficial effects of the utility model are: 1, avoid owing to consuming device enters automatically that waste of energy, equipment that electriferous state causes are aging, reduction of service life and burn out equipment, cause fire or other accidents.2, red power supply indicator and green relay indicating light are arranged, can clearly tell the state of a control that has or not power supply and power supply output.3, in this device protective tube is arranged, when serious overload of load or short circuit, can fast cut-off circuit prevent that accident from taking place.

Further specify below in conjunction with accompanying drawing.
