Abstract
A kind of safety socket, comprise a housing, firewire jack and zero line jack is provided with at the upper surface of housing, the live wire intermediate plate matched with it and zero line intermediate plate is provided with in the inside of housing, zero line is connected with zero line intermediate plate, live wire is connected with No. 1 terminals of a control circuit, and No. 2 terminals of control circuit are connected with live wire intermediate plate, is interval with No. 3 terminals and No. 4 terminals that are connected with control circuit above live wire intermediate plate.The utility model adopts such scheme, and before the zero line side of plug does not insert jack, the live wire intermediate plate in the firewire jack on socket is not charged, avoids, when plug does not stretch into completely, Danger Electric shock risk occurs, eliminate potential safety hazard; When children play, even if metallic article is inserted line receptacle, also can not there is the situation of getting an electric shock, eliminate Danger Electric shock risk, bring convenience to the life of people.
Description
Technical field:
The utility model relates to a kind of safety socket.
Background technology:
At present, socket on the market mostly structure is simple, if plug fails to stretch in socket completely in the process used, easily Danger Electric shock risk occurs, there is great potential safety hazard; If metallic article is inserted line receptacle in the process that children are at play, also can there is Danger Electric shock risk, bring inconvenience to the life of people.
Utility model content:
The utility model is in order to make up the deficiencies in the prior art, provide a kind of safety socket, its reasonable in design, before the zero line side of plug does not insert jack, live wire intermediate plate in firewire jack on socket is not charged, avoid, when plug does not stretch into completely, Danger Electric shock risk occurs, eliminate potential safety hazard; When children play, in time metallic article is inserted line receptacle, the situation of getting an electric shock also can not occur, eliminate Danger Electric shock risk, bring convenience to the life of people, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of safety socket, comprise a housing, firewire jack and zero line jack is provided with at the upper surface of housing, the live wire intermediate plate matched with it and zero line intermediate plate is provided with in the inside of housing, zero line is connected with zero line intermediate plate, live wire is connected with No. 1 terminals of a control circuit, and No. 2 terminals of control circuit are connected with live wire intermediate plate, is interval with No. 3 terminals and No. 4 terminals that are connected with control circuit above live wire intermediate plate, No. 1 pin that described control circuit comprises an optical coupler U1 is connected with No. 4 terminals by a resistance R1, No. 3 terminals are connected with a power circuit be connected with live wire producing 5V voltage, No. 2 pin ground connection of optical coupler U1 are arranged, No. 3 pins are connected with the grid of a field effect transistor Q1 by a resistance R2, the drain electrode of field effect transistor Q1 is connected with No. 1 terminals, the source electrode of field effect transistor Q1 is connected with No. 2 terminals, No. 4 pins of optical coupler U1 are connected with the positive pole of a battery BAT, a resistance R3 is provided with between resistance R2 and battery BAT negative pole, the negative pole of battery BAT is connected with No. 2 terminals again.
The utility model adopts such scheme, and before the zero line side of plug does not insert jack, the live wire intermediate plate in the firewire jack on socket is not charged, avoids, when plug does not stretch into completely, Danger Electric shock risk occurs, eliminate potential safety hazard; When children play, even if metallic article is inserted line receptacle, also can not there is the situation of getting an electric shock, eliminate Danger Electric shock risk, bring convenience to the life of people.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the circuit diagram of testing circuit of the present utility model.
In figure, 1, housing, 2, firewire jack, 3, zero line jack, 4, live wire intermediate plate, 5, zero line intermediate plate, 6, control circuit, 7, power circuit.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1-2, a kind of safety socket, comprise a housing 1, firewire jack 2 and zero line jack 3 is provided with at the upper surface of housing 1, be provided with the live wire intermediate plate 4 matched with it and zero line intermediate plate 5 in the inside of housing 1, zero line is connected with zero line intermediate plate 5, and live wire is connected with No. 1 terminals of a control circuit 6, No. 2 terminals of control circuit 6 are connected with live wire intermediate plate 4, are interval with No. 3 terminals and No. 4 terminals that are connected with control circuit 6 above live wire intermediate plate 4, No. 1 pin that described control circuit 6 comprises an optical coupler U1 is connected with No. 4 terminals by a resistance R1, No. 3 terminals are connected with a power circuit 7 be connected with live wire producing 5V voltage, No. 2 pin ground connection of optical coupler U1 are arranged, No. 3 pins are connected with the grid of a field effect transistor Q1 by a resistance R2, the drain electrode of field effect transistor Q1 is connected with No. 1 terminals, the source electrode of field effect transistor Q1 is connected with No. 2 terminals, No. 4 pins of optical coupler U1 are connected with the positive pole of a battery BAT, a resistance R3 is provided with between resistance R2 and battery BAT negative pole, the negative pole of battery BAT is connected with No. 2 terminals again.
During use, when plug is inserted into after in jack, the zero line pin of plug touches No. 3 terminals and No. 4 terminals, now, form loop, optical coupler U1 opens work, the field effect transistor Q1 used as switch is in opening state, No. 1 binding post and No. 2 binding posts are in connected state, and the live wire be connected with No. 1 binding post provides voltage to live wire intermediate plate, and now socket energising uses to supply power consumption equipment.After plug is extracted from socket, No. 3 terminals are no longer communicated with between No. 4 terminals, optical coupler U1 quits work, the field effect transistor Q1 used as switch is in off state, No. 1 binding post and No. 2 binding posts are in off state, the live wire be connected with No. 1 binding post no longer provides voltage to live wire intermediate plate, now socket power-off.
Adopt safety socket of the present utility model, before the zero line side of plug does not insert jack, the live wire intermediate plate in the firewire jack on socket is not charged, avoids, when plug does not stretch into completely, Danger Electric shock risk occurs, eliminate potential safety hazard; When children play, even if metallic article is inserted line receptacle, also can not there is the situation of getting an electric shock, eliminate Danger Electric shock risk, bring convenience to the life of people.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
