Abstract
The utility model provides a timing power socket. The timing power socket comprises a control unit, a timer, an external power supply, and a plurality of power outlets. The power outlets are connected with the external power supply via normally-open relays. The timer and the normally-open relays are connected with the control unit. Current sensors are connected between the normally-open relays and the external power supply. The current sensors are connected with the control unit. The external power supply is also connected with a voltage sensor. The voltage sensor is connected with the control unit. Timing power supplying can be achieved by the multiple power outlets at the same time, and the timing arrangement of the power outlets is mutually independent. The timing power socket is safe and convenient to use, has a simple structure, and helps to prevent and minimize accidents caused by overloading and overcurrent of power-consuming equipment or the power socket itself.
Description
Technical field
The utility model belongs to electric equipment technical field, relates to a kind of regular convenience receptacle.
Background technology
Along with a large amount of uses of the rechargeable devices such as mobile phone, panel computer, electric shaver, all kinds of regular sockets on market, are there are, regular socket can be the said equipment timing charging by the charging interval is set, prevent the charging interval long cause rechargeable devices and battery impaired, affect useful life.But how existing regular socket just sets up a timer and diverter switch on common socket basis, generally can only realize the timing function of a power output, and the universal use of regular socket is restricted.In addition, in existing regular socket use procedure, if electrical appliance or socket itself break down, while causing circuit overcurrent or overload, supply socket is open circuit in time, has affected the use safety of supply socket.
Utility model content
The purpose of this utility model is to provide a kind of regular convenience receptacle, mainly solves existing regular socket and cannot realize multiple power outputs timing power supply and unsafe problem of use simultaneously.
For this reason, the utility model adopts following technical scheme:
A kind of regular convenience receptacle, comprise control unit, timer, external power source and some power outputs, described each power output is connected with external power source by open type relay respectively, and described timer and open type relay are connected with control unit respectively.
Further, between described open type relay and external power source, be also connected with current sensor, described current sensor is connected with control unit.
Further, described external power source is also connected with voltage sensor, and described voltage sensor is connected with control unit.
Further, described control unit is single-chip microcomputer.
The beneficial effects of the utility model are: can realize multiple power outputs timing power supply simultaneously, and the time set of each power output is separate; Use safety, can carry out Real-Time Monitoring to the operating current of power output, can cut off in time overload or the power output of overcurrent, avoid and reduce the various accidents that cause because of power consumption equipment or institute's supply socket self overload, overcurrent; Simple in structure, easy to use.
Brief description of the drawings
Fig. 1 is structure principle chart of the present utility model;
Fig. 2 is external structure schematic diagram of the present utility model.
In figure, 1-control unit, 2-external power source, 3-power output, 4-open type relay, 5-current sensor, 6-timer, 7-voltage sensor.
Embodiment
As shown in Figure 1, a kind of regular convenience receptacle, comprise control unit 1, timer 6, external power source 2 and some power outputs 3, each power output 3 is connected with external power source 2 by open type relay 4 respectively, and be also connected with current sensor 5 between open type relay 4 and external power source 2, external power source 2 is also connected with voltage sensor 7, and timer 6, open type relay 4, current sensor 5 and voltage sensor 7 are connected with control unit 1 respectively.In the utility model, control unit 1 is single-chip microcomputer, and its model is STC15F2K60S2.In figure, thick lines represent supply line, and hachure represents signal line.
Operation principle of the present utility model is as follows:
Under normal circumstances, open type relay 4 is in off-state.In the time using timing power supply function, power supply opening time and the dwell time of a certain or certain several power output 3 are set by timer 6, in the time that timer arrives wherein a power output power supply opening time 6 instruction times, the signal that this power output is opened power supply by timer 6 transfers to control unit 1, control unit 1 is controlled the open type relay closes corresponding with this power output, this power output starts power supply immediately, when time that this power output is stopped power supply then, timer 6 transfers to control unit 1 by the signal of stopping power supply again, control unit 1 is controlled open type relay and is disconnected, the power supply of this power output finishes immediately.Certainly,, when the power-on time of power output 6 is set to 24h, can realize the round-the-clock power supply of power output.
In addition, with in electric process, the voltage signal of the current signal of the each power output 3 detecting and external power source 2 is transferred to respectively control unit 1 by current sensor 5 and voltage sensor 7.In the time that the current value of a power output wherein exceeds the default current threshold of control unit 1; control unit 1 is controlled the open type relay being connected with this power output and is disconnected; thereby protection is connected in power consumption equipment on this power output and the safety of supply socket, prevent that overload and overcurrent from causing power consumption equipment damage.In the time that the magnitude of voltage of the external power source 2 detecting is undesired; for example, while exceeding supply socket load voltage value; control unit 1 is controlled all open type relays 4 and is disconnected, thereby power output 3 is all stopped power supply, and protects the safety of connected power consumption equipment with this.
Claims (4)
1. a regular convenience receptacle, it is characterized in that, comprise control unit, timer, external power source and some power outputs, described each power output is connected with external power source by open type relay respectively, and described timer and open type relay are connected with control unit respectively.
2. a kind of regular convenience receptacle according to claim 1, is characterized in that, between described open type relay and external power source, is also connected with current sensor, and described current sensor is connected with control unit.
