Abstract
The utility model belongs to the field of hardware and electrical equipment and particularly provides a power strip comprising a housing, connecting terminals disposed inside the housing, a plug power supply circuit serially connected with the connecting terminals, a transformer rectifier module mounted inside the housing, a current detection module, an AD conversion module, a controller, and a switching circuit module. The connecting terminals are respectively electrically connected with the current detection module, the AD conversion module, the controller and the switching circuit module through the transformer rectifier module. The output end of the current detection module is connected with the controller through the AD conversion module. The controller is connected with the switching circuit module in order to control on and off of the switching circuit module and on and off of the plug power supply circuit. A detection circuit of the current detection module is serially connected between the connecting terminals and the plug power supply circuit. The power strip has the function of automatically detecting whether or not the circuit bears exceeded load power and the functions of power-off protection and power restoration; tripping or short circuit and fires caused by overload power utilization are avoided, and safety of power utilization is improved.
Description
Technical field
The utility model belongs to hardware and electrical equipment field, is specifically related to a kind of main plate.
Background technology
Along with household electrical appliance popularizing in resident's daily life, when offering convenience to people, its security also causes people's attention day by day; Existing plate does not have the function whether detection plate exceeds bearing power; people often ignore the power that plate can be loaded in the process of electricity consumption; or be constantly connected in series plate, to reach the object that separates more sockets, do like this; often there will be trip phenomenon; have influence on other people electricity consumption, the more important thing is like this and do, easily burn out plate; cause short circuit, cause fire.
Summary of the invention
The purpose of this utility model is to overcome existing plate not possess the problem that detects plate bearing power.
For this reason, a kind of plate, the plug current supply circuit that comprises housing, is arranged on the connection terminal in housing and is connected in series with this connection terminal, also comprises and is arranged on transformation rectification module, current detection module, AD modular converter, controller, on-off circuit module in housing; Connection terminal is electrically connected to current detection module, AD modular converter, controller, on-off circuit module respectively through transformation rectification module, the output terminal of current detection module is connected with controller through AD modular converter, controller is connected to control the break-make of this on-off circuit module with on-off circuit module, to control described plug current supply circuit break-make, the testing circuit of current detection module is serially connected between connection terminal and plug current supply circuit.
Plate also comprises display screen, the hummer being connected with controller.
The beneficial effects of the utility model: this plate that the utility model provides, the plug current supply circuit that comprises housing, is arranged on the connection terminal in housing and is connected in series with this connection terminal, also comprises and is arranged on transformation rectification module, current detection module, AD modular converter, controller, on-off circuit module in housing, connection terminal through transformation rectification module respectively with current detection module, AD modular converter, controller, on-off circuit module is electrically connected to, the output terminal of current detection module is connected with controller through AD modular converter, controller and on-off circuit module are connected to control the break-make of this on-off circuit module, to control described plug current supply circuit break-make, the testing circuit of current detection module is serially connected between connection terminal and plug current supply circuit, whether this plate can exceed function bearing power and that carry out power-off protection and restore electricity by testing circuit, avoid because trip phenomenon or the short circuit that overburden electricity consumption brings, the generation of fire, improve the security of electricity consumption.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is plate schematic diagram.
Fig. 2 is that plate is controlled current flow path schematic diagram
In figure: 1, housing; 2, connection terminal; 3, shift knob; 2, display screen.
Embodiment
Embodiment 1:
A plate, comprises housing and is arranged on current detection module, AD modular converter, controller in housing, on-off circuit module, transformation rectification module as shown in Figure 1 and Figure 2; Transformation rectification module is current detection module, AD modular converter, controller, and on-off circuit module provides power supply; Current detection module is connected with controller by AD modular converter, and controller is connected with on-off circuit module; Whether this plate can testing circuit exceeds the function of bearing power, avoids because the generation of the trip phenomenon that overburden electricity consumption brings or short circuit, fire, improves the security of electricity consumption.
Embodiment 2:
On the basis of embodiment 1, shown in plate also comprise display screen or the hummer being connected with controller, display screen can show the output power of plate in time, hummer can sound the alarm when exceeding load.
When the switch 3 of plate is closed, plate is just in running order, transformation rectification module can be just current detection module, AD modular converter, controller, and on-off circuit module provides power supply, and current detection module just can constantly detect the electric current in plate loop, and send result to AD modular converter, the signal that AD modular converter is sent current detection module here carries out digitizing, then sends controller to, and controller is controlled display screen, show current power, current information; Current value when current value surpasses safety utilization of electric power, will disconnect plate loop by gauge tap circuit module, and control hummer and send chimes of doom, and then time delay is after 5 minutes, and gauge tap closing of circuit loop, continues to detect the current information in loop, so circulation.
In sum; be not difficult to find out the plate that above embodiment provides; can automatically detect the output power of plate and carry out power-off protection and recover the function of power-off, avoiding, because exceed the generation of trip phenomenon that load electricity consumption band likes or short circuit, fire, improving the security of electricity consumption.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection scope of the present invention.
