After the socket is used for some time delaying, the electric appliance and the entire power supply of the socket are capable of being automatic cut out. When the electric voltage goes beyond 250V, the utility model is immediately automatic cut out, which ensures that the electric appliance and the socket are not damaged. The utility model is mainly characterized in that the inner box body comprises an integral circuit which is composed of a current detecting control circuit, an electric voltage detecting control circuit, a delaying switching off control circuit, a power supply step-down and commutation filtering circuit, a control and execute indicating circuit.
Description
The utility model is a kind of socket that complete closedown is energy-saving, service life prolonged and protection electrical equipment is not damaged by overvoltage that is used for remote control electrical appliance.
At present, most remote control home appliances after the shutdown that uses a teleswitch, does not disconnect all power supplys as remote control color tv, video tape recorder, high end audio etc.; Its remote control receiving unit needs to consume the electric energy of 4～8W still in work, and has influenced the useful life of household electrical appliance.Because the existence of above-mentioned drawback, people have to pull up the appliances power source plug after the shutdown that uses a teleswitch, increase the trouble in the use.Simultaneously, this class remote control home appliance has only the low-voltage variation function usually, and for example remote control color tv comes to this; Perhaps have only the low pressure operation function, for example video recorder comes to this, and does not but all have over-voltage protecting function.When voltage ripple of power network breaks down overtension than big and electrical network, will burn used household electrical appliance.More than be the two big shortcomings that present remote control electrical appliance exists.
The purpose of this utility model is to provide a kind of novel power supply socket that can make remote control electrical appliance complete closedown and protection electrical equipment not damaged by overvoltage.Use this supply socket to overcome and do not cut off the power supply the source after the shutdown that present remote control electrical appliance exists and do not have overvoltage protection two big shortcomings.
The utility model is finished with following mode: it has box body (1), there are jack (CZ), indicator light (LED), button (QA) in its front, there is installing hole (2) at its two ends, and plug (CT) is arranged, in box body (1), have by current detection control circuit, voltage detecting and controling circuit, time delayed turn-off control circuit, power supply decompression rectifier filter circuit, control and carry out the integrated circuit that indicating circuit constitutes.Described current detection control circuit is by transformer (B
