Abstract

An energy-saving security brownout memory socket comprises an insulation shell, a power output socket, a control circuit that has brownout memory and with a thyristor as a main component. A connected-on button and a connected-off button are positioned on the socket so as to realize the operations of disconnection and connection of a power supply to electrical appliances; a power indicator and an insurance tube are also positioned and used respectively to indicate power and extra-current protection. The technical point of the utility model is that when lacking of working power, the thyristor enters the shutdown state; while power supply resumes, the thyristor keeps the shutdown state because of lacking trigger signals. By using the characteristic of brownout memory, the inadequacy that the existent power socket can not keep brownout memory when power supply is cut off can be solved, so as to avoid problems caused by the inadequacy such as automatic operation of appliances, waste of electric energy, electric shock accidents, aging equipment, equipment failures and fires.

Description

Energy-saving safety power-failure memory socket

Affiliated technical field

The utility model relates to the supply socket in a kind of low-voltage electrical apparatus field, especially electrical appliance is had the supply socket of energy-conservation, safe effect and power-failure memory function.

Background technology

At present, mainly be made up of insulation crust and metal spring leaf in that the widely used supply sockets in place such as family, office, hotel, market are general, insulation crust plays protective action, and metal spring leaf is accepted the electrical appliance attaching plug, and to its out-put supply.This conventional electrical outlet can not be closed its power supply output action automatically after the power supply supply loses, promptly can not remember the power supply power-fail state, when sending a telegram here once more, if forgotten the mains switch of turning off electrical appliance, then electrical appliance will turn round voluntarily, not only waste electric energy in vain, also often cause equipment fault, person electric shock and fire incident etc.

Summary of the invention

Can not remember the deficiency of power-down state in order to overcome the existing power supply socket, the utility model provides a kind of novel power supply socket, this socket not only can switch on or off power supply output according to user's wish, and can supply with at incoming power and lose back memory power-down state automatically, even after recovering the power supply supply, this socket does not still have power supply output, unless by the manual operation output that can restore electricity.

The technical scheme that its technical problem that solves the utility model adopts is: its structure is that to have set up on existing power supply socket basis be the electronic control circuit with power-failure memory function that main element constitutes with the thyristor, and circuit theory diagrams as shown in Figure 1.After binding post L, N, PE connect supply line, when power supply just often, LED 1 is lighted, but power supply accessory power outlet XS1 and XS2 no-output.When pressing push button SB1, power supply makes its conducting through resistance R 1 and push button SB1 triggering thyristor VT1, power supply accessory power outlet XS1, XS2 obtain out-put supply, again because the phase shift effect of resistance R 2, capacitor C 2, when the voltage zero-cross of power supply, the electric current of this branch road is non-vanishing, thyristor VT1 is in the conducting that is triggered of other half period, so thyristor VT1 keeps conducting state, even unclamp push button SB1, power supply accessory power outlet XS1, XS2 have power supply output in the same old way.Cut off the power supply of power supply accessory power outlet XS1, XS2 as need and export, only need press shutoff button SB2 and get final product.Supply with if having no progeny during the power supply of terminal L, N is supplied with and recover, because push button SB1 is in (disconnection) state that resets, thyristor VT1 is in cut-off state because of Triggerless, power supply accessory power outlet XS1, XS2 do not have power supply output, system is in the power-failure memory state, unless press push button SB1, just can make power supply accessory power outlet XS1, the XS2 output that restores electricity.
