It is that some functional circuits on circuit board are powered, to complete specific function after separation.
The circuit structure and its operation principle laid on the circuit board of the present embodiment are explained in detail with reference to Fig. 6
State.
As shown in fig. 6, being laid with power-switching circuit 252, control circuit 251, nothing on the circuit board 250 of the present embodiment
Line communication module（Such as WiFi module 253, GSM/CDMA modules 254）Deng functional circuit, the electricity for being built-in with battery 270
For source patchplug 1, further charge management circuit 255 can also be set on circuit board 250, be connected to Power convert electricity
Between road 252 and battery 270, for when the power adapter plug 1 is inserted into power outlet, being carried using power outlet
The externally fed of confession is the battery 270 charging accumulation of energy.
In the present embodiment, the input of the power-switching circuit 252 can be connected by the second flexible PCB 232
Pin 230 is patched, the externally fed accessed by contact pin 230 is converted on circuit board 250 other work needed for using electric loading
Power supply（Such as low-voltage dc power supply）, it is the control circuit 251, wireless communication module 253,254 and charge management circuit
255 grade electricity consumption load supplyings.Electromagnet 260 and wireless communication module 253,254 are connected to control circuit 251, pass through control
The control wireless communication module 253,254 of circuit 251 completes the transmitting-receiving of radiofrequency signal, and carries out control system of switching on or off electricity to electromagnet 260.
When needing electric equipment plug-in to run, power adapter plug 1 can be inserted into power outlet first, for example
It is inserted into the 220V AC Power supply sockets in user family；Then, the attaching plug of electric equipment is inserted into power supply transfer to insert
In first 1 jack 221, Alternating Current Power Supply is obtained by power adapter plug 1 indirectly.
In power adapter plug 1 described in grafting, the plug slice 130 of preceding plug 100 can be inserted into power supply first
In socket, because the plug slice 130 of preceding plug 100 is electrically connected with Plug pin patch bay 140, therefore on Plug pin patch bay 140 with
220V alternating currents.Then, before the contact pin 230 of rear plug 200 is inserted into the Plug pin patch bay 140 of plug 100, connect contact pin 230
Logical 220V Alternating Current Power Supply.Now, electricity operation on the power-switching circuit 252 on circuit board 250,220V Alternating Current Power Supplies are changed
Into dc source, transmit to control circuit 251, wireless communication module 253,254 and charge management circuit 255, make each function electricity
Lu Shang electricity is run.Control circuit 251 it is upper electricity operation after, first control electromagnet 260 be powered, produce magnetic field, with preceding plug
The adhesive of magnet attraction portion 150 in 100, then ensures that preceding plug 100 can be solidly joined with rear plug 200, as shown in Figure 8.This
When, received because the attaching plug of electric equipment is inserted into inserted sheet by the jack 221 of rear plug 200 in shell fragment 240, and inserted sheet
Receive shell fragment 240 to connect with contact pin 230 further through the second flexible PCB 232, therefore, 220V Alternating Current Power Supplies are just sent to electricity
The attaching plug of device equipment, makes electricity operation on electric equipment.
The control circuit 251 communicates after upper electricity operation with the wireless communication module 253,254, waits to be received remote
The power-off signal that process control terminal is sent.The remote control terminal can be smoke alarm, temperature alarm, mobile phone etc.,
When smoke alarm detect smokescope it is exceeded when, or temperature alarm detect environment temperature more than higher limit when, or
When person user is intended to the power-off of control apparatus equipment physics by mobile phone, generated by smoke alarm, temperature alarm or mobile phone disconnected
Electric signal, and send in a wireless form to the power adapter plug 1.The power adapter plug 1 is wireless using its inside
Communication module 253,254 receives described power-off signal, and is converted into analog signal or digital data transmission to described control
Circuit 251.The control circuit 251 is after power-off signal is received, and the power supply of tripping magnet 260 makes magnetic field disappear.This
When, rear plug 200 is separated in the presence of its gravity from preceding plug 100, as shown in figure 9, so that electric equipment
Supply line physics disconnect, realize thoroughly power-off.
When magnet attraction portion 150 for being set in preceding plug 100 is magnet, control circuit 251 is receiving power-off
After signal, the electromagnetism in rear plug 200, with the magnetic of conversion of electromagnetic iron 260, can be made with the current electrode of conversion of electromagnetic iron 260
Iron 260 and the mutual magnetic repulsion of magnet 150 in preceding plug 100, then in the presence of repulsive interaction, make rear plug 200 and preceding plug
100 separation, realize the physics power-off of electric equipment.
Power adapter plug 1 for being built-in with battery 270 in rear plug 200, in rear plug 200 from preceding plug 100
After disengaging, now, the contact pin 230 in rear plug 200 has cut off slotting due to being separated with the Plug pin patch bay 140 in preceding plug 100
The connection that pin 230 is powered with external communication.Now, the power-switching circuit 252 on circuit board 250 power off it is out of service, change by
Battery 270 is that the control circuit 251 and wireless communication module 253,254 are powered.Using controlling 251 pairs of circuit by contact pin
The power supply of 230 accesses is detected, specifically can detect slotting by the way of voltage sampling circuit or current sampling circuit is set up
It is whether powered on pin 230, or by detecting whether power-switching circuit 252 has dc source output to judge contact pin indirectly
It is whether powered on 230.When detecting unpowered access on contact pin 230, it is believed that rear plug 200 departs from from preceding plug 100.
Now, the confirmation signal that has been separated with preceding plug 100 of plug 200 after the generation of control circuit 251 is represented, is transmitted to described wireless
Communication module 253,254, and then radiofrequency signal is converted into by wireless communication module 253,254, send to specified long-range control
The mobile phone of terminal processed, such as user, to notify user's " physics is powered off electric equipment ".
The control circuit 251 cuts off battery 270 after control wireless communication module 253,254 will confirm that signal is sent
Even the supply line of connection control circuit 251 and wireless communication module 253,254, makes control circuit 251 and wireless communication module
253rd, 254 is out of service, saves electric energy.
