2 and a microswitch 3, for the outlet of three jacks 4, photo resistance 2 and microswitch 3 are arranged side by side in three
The center of a jack 4；For the outlet of two jacks 4, photo resistance 2 and microswitch 3 are located side by side at two
Between a jack 4.
As shown in figure 3, the control circuit of this wall surface safe socket includes controller, relay and above-mentioned photo resistance
2 and microswitch 3, photo resistance 2 signal input part of controller is connected with the signal output end of microswitch 3, controller
Signal output end connects the driving signal input of relay, two normally opened contacts point of relay by conventional driving circuit
Not Jie Ru AC power source firewire L and zero curve N circuit in.Microswitch 3 uses self-replaced type microswitch.
Specific work process and working principle are as follows：
On daytime, when being not inserted into plug on light more abundance and jack 4 within doors, light is irradiated in photo resistance 2, light
Quick resistance 2 exports high-impedance state to controller（Or low resistance state）Signal, while microswitch 3 is in non-triggering state, to controller
Export low level（Or high level）The normally opened contact of signal, the relay of controller control at this time is in normally open, in jack 4
Copper bar is not charged.
After plug is inserted into jack 4 and fits closely with front panel 1, plug blocks photo resistance 2, this time
The resistance states of quick resistance 2 invert, and plug touches the triggering end of microswitch 3 simultaneously, to control after the triggering of microswitch 3
Device processed issues level signal and equally inverts, and controller judges there is plug insertion in jack 4, and it is dynamic that controller controls relay
Make, the normally opened contact closure in relay, AC power source exports electric energy outward, controller simultaneously by the triggering state of relay into
Row locking, therefore plug, after reliable insertion, the electric power thus supplied in jack 4 is no longer because of the variation of 3 triggering state of microswitch
And change, therefore appearance the case where the frequent on-off of power supply caused by avoiding microswitch 3 due to internal mechanical structure is unreliable.
After plug is extracted, light irradiates photo resistance 2 again, and the state of photo resistance at this time 2 and microswitch 3 is again
Original state is returned to, controller controls relay and resets, and the normally opened contact in relay is again off.
It can be seen from the above, this wall surface safe socket only after plug is reliably inserted into jack 4 just can power transmission, plug pulls out
Copper bar after out in controller control jack 4 powers off at once, thus when avoiding socket zero load children from getting electric shock danger.
In the dark surrounds at night, in the initial state, since microswitch 3 is not pressed, relay is still
In reset state, the copper bar in jack 4 is not charged, when needing using socket at night, needs by illuminations, therefore work as
After the illumination that illuminations issues is mapped to photo resistance 2, photo resistance 2 returns to reset condition after illuminated, and plug insertion is inserted
After hole 4, controller can be triggered relay according to above-mentioned principle.
After night extracts plug, light is not irradiated photo resistance 2 in external environment, and relay is being controlled
Triggering state is locked under the control of device processed, therefore the copper bar after the extraction of night plug in jack 4 is in electriferous state, but
It is after needing to reuse socket or daybreak, illuminations or sunlight are irradiated to photo resistance 2 in a flash again, controller
At once control relay disconnect, therefore ensure that the full extent night using safe.
