Abstract
A photoinduction anti-electric shock socket comprises a control chip, a relay, a current sensor, jack metal contacting sheets, a light-emitting diode and a photosensitive diode; the relay controls the jack metal contacting sheets to be connected with a mains supply; the current sensor detects current of an end of the jack metal contacting sheets; light energy emitted by the light-emitting diode passes through the socket; light rays sent to the socket are inducted by the photosensitive diode; and an input end of the control chip is connected with the current sensor and the photosensitive diode, and an output end of the control chip is connected with the relay. The relay is connected between the metal contacting sheets and the mains supply in the photoinduction anti-electric shock socket; and only when no current flows through the socket and a human body and other ray reflectors are at front of the socket, the control chip starts the relay in a relay manner, and the power supply of the socket is conducted, so electric shocks caused by touching the socket or the jack metal contacting sheets by mistakes are effectively prevented.
Description
Technical field
The utility model relates to a kind of commercial power socket, is specially photoinduction anti-electric shock socket.
Background technology
The supply socket that at present sells market is numerous, come in every shape, multifarious, but be exactly mostly there is no anti-electric shock apparatus, the user careless slightly danger that just has electric shock, especially child's curiosity, once there were many children to insert in jack with iron nail or other article, bred a tragedy.
Utility model content
The purpose of this utility model is: a kind of safer photoinduction anti-electric shock socket is provided.
In order to achieve the above object, the technical scheme adopting is: photoinduction anti-electric shock socket, and it comprises control chip, relay, current sensor, jack metal contact piece, light-emitting diode and photodiode; Described Control jack metal contact piece is connected with civil power; Described current sensor detects the electric current of jack metal contact piece end; The luminous energy that described light-emitting diode sends sees through socket; Described photodiode can sense the light of directive socket; The input of described control chip connects current sensor and photodiode, and output connects relay.
Described light-emitting diode and photodiode are respectively infrarede emitting diode and infrared induction diode.
Described light-emitting diode is provided with light-shielding layer or reflector outward, makes light directive socket front that it sends and direct directive photodiode not.
Adopt the beneficial effect of technique scheme to be: between the Metal Contact sheet in this photoinduction anti-electric shock socket and civil power, to be connected with relay, in the time that there are the light reflection things such as human body in socket no current and socket front, control chip is meeting delayed startup relay, the power supply of conducting socket, effectively prevents false touch socket or plug metal contact piece and the electric shock that causes.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model photoinduction anti-electric shock socket.
In figure: 1-control chip, 2-relay, 3-current sensor, 4-jack metal contact piece, 5-light-emitting diode, 6-photodiode.
Embodiment
Below in conjunction with drawings and Examples, the utility model is explained.
Photoinduction anti-electric shock socket, it comprises control chip 1, relay 2, current sensor 3, jack metal contact piece 4, light-emitting diode 5 and photodiode 6; Described relay 2 is controlled being connected of jack metal contact piece 4 and civil power; Described current sensor 3 detects the electric current of jack metal contact piece 4 ends; The luminous energy that described light-emitting diode 5 sends sees through socket; Described photodiode 6 can sense the light of directive socket; The input of described control chip 1 connects current sensor 3 and photodiode 6, and output connects relay 2.
The operation principle of this socket is: when jack metal contact piece 4 no current, and in the time that photodiode 6 detects the light that the light-emitting diode 5 of human body reflection sends, control chip 1 delayed startup relay 2, conducting jack metal contact piece 4 and civil power; Socket metal contact piece 4 represents while there being electric current that plug has inserted socket, and relay keeps conducting; In the time of socket metal contact piece 4 current vanishes, control chip immediately control relay disconnects; So circulation.
Described light-emitting diode 5 and photodiode 6 are respectively infrarede emitting diode and infrared induction diode.
Described light-emitting diode 5 is outer is provided with light-shielding layer or reflector, makes light directive socket front that it sends and direct directive photodiode 6 not.
