Continuing with reference to Fig. 3, plug insertion is slotting in a kind of embodiment one of electrical source socket of the utility model During seat, the position relationship schematic diagram between the position of plug base pin and infrared sensing switch 21.Wherein, every a pair of infrared inductions are opened Closing 21 all includes an infrared transmitting tube 211 and an infrared receiving tube 212.Infrared transmitting tube 211 and infrared receiving tube 212 The inner side of a sleeve 23 is arranged at, and it is staggered relatively.When plug 90 inserts the socket, the insertion of pin 91 of the plug 90 should Between infrared transmitting tube 211 and an infrared receiving tube 212, now, then infrared receiving tube 212 does not receive infrared transmitting tube 211 infrared rays sent.

Also referring to Fig. 4 and Fig. 5, microcontroller in a kind of embodiment one of electrical source socket of the utility model Device controls the circuit theory diagrams of infrared sensing switch.

Due to multiple infrared transmitting tubes 211, infrared receiving tube 212 occurring in the circuit diagram, for the ease of statement pair It should be related to, infrared transmitting tube 211 is numbered for we, and its numbering is D1 and D2.Wherein, D1 include be connected in parallel two it is red Outer transmitting tube D1-1, D1-2；D2 includes two infrared transmitting tubes D2-1 and D2-2 being connected in parallel.Infrared receiving tube 212 enters Line number is that its numbering is Q1-1, Q1-2, Q2-1 and Q2-2.Wherein, D1-1 and D1-2 is distributed across same socket (three Pin socket or bipod socket) in infrared transmitting tube；Likewise, D2-1 and D2-2 are distributed across another socket, (bipod is inserted Seat or three-pin socket) in infrared transmitting tube.

Wherein, two infrared transmitting tubes in same socket are connected in parallel between two output ends of microcontroller 27, But two infrared transmitting tubes for being connected in parallel respectively corresponding to infrared receiving tube, then be connected to different defeated of the microcontroller Enter between end and ground.

Specifically, as shown in figure 5, infrared transmitting tube D1-1 and D1-2 are connected in parallel in the output end P1.0 of microcontroller 27 The input P1.6 and ground of microcontroller 27 are then arranged at P1.1, infrared receiving tube Q1-1 corresponding with infrared transmitting tube D1-1 Between；Infrared receiving tube Q1-2 corresponding with infrared transmitting tube D1-2 be then arranged at another input P1.5 of microcontroller 27 with Between ground.

Likewise, infrared transmitting tube D2-1 and D2-2 are connected in parallel in the output end P1.0 and P1.2 of microcontroller 27.With Infrared receiving tube Q2-1 is then arranged between the input P1.6 of microcontroller 27 and ground corresponding to infrared transmitting tube D2-1；With it is red Infrared receiving tube Q2-2 corresponding to outer transmitting tube D2-2 is then arranged between another input P1.5 of microcontroller 27 and ground.D3 Connected mode as shown in figure, principle is identical similarly, then repeats no more.

Please continue to refer to Fig. 6, its for one in a kind of embodiment one of electrical source socket of the utility model after The control principle drawing of electrical equipment.

Likewise, due to more than one relay 26, therefore we are also also carried out to controlling switch E corresponding to relay 26 Numbering.It is a socket position in present embodiment one, then has two sockets, therefore controlling switch corresponding to relay 26 E numbering is followed successively by E1 and E2.

It is visible in Fig. 4, the controlling switch E1 and E2 of the control output end control relay 26 of microcontroller 27 cut-off And conducting.That is, when microcontroller 27 determines to have plug insertion socket according to the infrared sensing switch of conducting, then controller 27 Control output end controls controlling switch corresponding to the infrared sensing switch to turn on；Conversely, then control its disconnection.Optimization, micro-control Device 27 processed determines whether turn on the infrared sensing switch according to the infrared sensing switch and default security mechanism of conducting Corresponding controlling switch E1 or E2.Specifically, the security mechanism includes：The ON time of the infrared sensing switch is in preset range Within just turn on controlling switch corresponding to the infrared sensing switch, such as 0.1 second；Or plug leaves more than socket certain distance, Also it can disconnect or be not turned on controlling switch corresponding to the infrared sensing switch；Or if conducting infrared sensing switch not In same socket, then corresponding relay will not be connected.On the particular content and implementation of security mechanism, under Text, which has, to be elaborated.

Specifically, as shown in fig. 6, controlling switch E1 is connected between the P1.1 and P1.2 of microcontroller 27.In figure 6 may be used To see, relay K1 and switch E11 are connected in series between power supply and ground, and controlling switch E1 then controls switch E11's Unlatching is led to road.That is, between controlling switch E1 is connected to 27 two output ends of microcontroller when exceeding certain threshold value, i.e., When P1.2 is high level, P1.1 is low level, controlling switch E1 conductings, so that switch E11 also reaches the threshold value of conducting, So that relay K1 is powered, finally socket corresponding with relay K1 is powered.Wherein, controlling switch E1 and switch E1 may each be the electron transistor with switching function such as triode or metal-oxide-semiconductor and form.

Optimization, a LED1 can also be connected in parallel with relay K1, be powered successful indicator lamp as the socket 25。

It refer to Fig. 7, the pulse pattern schematic diagram of the output end of microcontroller 27 in present embodiment one.

P1.1, P1.2, P1.0 export high level in succession.When P1.1 exports high level, P1.2 is arranged to high-impedance state, then Infrared transmitting tube D1-1 and D1-2 are lit transmitting infrared ray, now, if respectively corresponding infrared receiving tube Q1-1 with Q1-2 have received infrared ray, then infrared receiving tube Q1-1 turns on ground connection with Q1-2, then the input P1.5 of microcontroller 27 with P1.6 turns into low level, and then control output end controls relay corresponding to the infrared sensing switch to connect to microcontroller 27；If this When the socket on insert plug, then infrared receiving tube Q1-1 and Q1-2 do not receive infrared ray, then are still in cut-off state, That is, the input P1.5 and P1.6 of microcontroller 27 is still high level, then then control output end controls this infrared to microcontroller 27 Relay is off corresponding to inductive switch.That is, microcontroller 27 connects according to the infrared of the infrared inductive switch Closed tube Q1-1 and Q1-2 state, relay corresponding to control are open or closed.As it was previously stated, microcontroller 27 can also increase The judgement of security mechanism, come the state for determining the disconnection of control relay with connecting.Wherein, high-impedance state is the defeated of microprocessor 27 Go out a kind of different output state at end, neither high level, nor low level, it equivalent to the output for disconnecting P1.2, so as to The operation of whole sequential is not interfered with.It is that can support this output state of high-impedance state in current existing microprocessor 's.

Optimization, as it was previously stated, a safety detection switch 24 can also be set on the circuit board 20, likewise, its is right The infrared transmitting tube D3-1 answered, infrared receiving tube Q3-1.As aforementioned principles, infrared transmitting tube D3-1 is connected to microcontroller Between two output ends of device 27.Microcontroller 27 drives infrared transmitting tube D3-1 transmitting infrared rays, as infrared receiving tube Q3-1 In the conduction state when can receive infrared ray, its corresponding output of microcontroller 27 is in low level state；When infrared When reception pipe Q3-1 can not receive infrared ray, in cut-off state, its corresponding output of microcontroller 27 is in high level State.Infrared detection in sleeve of the microcontroller 27 by detecting the socket simultaneously switchs and switchs 24 with the safety detection The on or off situation of corresponding infrared detection switch, to determine whether to open the relay of respective socket.Thus, even if socket Jack in insert metal objects simultaneously, but because it is not normal plug, centre will not switch safety detection 24 pressures Go down, then the relay of the socket does not turn on yet, in fact, if it is desired to inserting metal object respectively in two pins of socket Part, the same time, and the probability that safety detection switch 24 is also subdued is minimum, and difficulty is also very big.Simultaneously as this is examined safely The head 241 of slowdown monitoring switch 24 is very short and small, as we can be set to 2 millimeters of length, that is to say, that when the bottom surface of plug After 92 leave 2 millimeters of socket (as shown in Figure 3), safety detection switch 24 just pops up, the afterbody of safety detection switch 24 242 just eject from corresponding sleeve, and the infrared receiver switch in the sleeve then turns on, and microcontroller 27 disconnects the safety detection Relay 26 corresponding to switch 24, so, as long as more than 2 millimeters from socket of plug 90, socket with regard to no power, 2 millimeters away from From human hand is inserted not enter, so as to ensure the Electrical Safety of user.Thus, the safety of the socket is further improved Property.By safety detection switch 24 come controller plug when apart from socket certain distance, disconnecting the relay of socket, be allowed to can not Power supply, this is one of security mechanism.

Optimization, microcontroller 27 can also judge whether two infrared detection switches simultaneously turn in socket and bush, or Person conducting time difference whether within a default threshold value, such as 0.1 second, if it is, microcontroller 27 determine insertion It is normal plug, controls relay conducting corresponding with the socket；If it is not, then be defined as improper insertion, it is not turned on pair The relay answered.Trigger electric shock accidents in this way, a metal device can be reduced and be inserted respectively into the jack of socket.Certainly, such as The fruit socket position also includes a safety detection and switchs 24, then microcontroller 27 need to judge that two infrared detections are opened in socket and bush Close and the safety detection switchs whether infrared detection switch corresponding to 24 simultaneously turns on, or whether the time difference turned on is one Within individual default threshold value.By microcontroller 27 judge infrared sensing switch ON time whether the default time difference it Interior, just connecting within the default time difference, this is the two of security mechanism.

Optimization, whether the infrared sensing switch that microcontroller 27 can also judge to simultaneously turn on is peace in a socket Full inductive switch, if it is, relay corresponding to connecting；If it is not, then disconnect corresponding relay.And turn on red Whether outer inductive switch is in same socket, and the mapping relations between infrared sensing switch and relay, and being all can be with It is default in the programming process of circuit design process and microcontroller 27, as those skilled in the art according to this practicality What the scheme that new embodiment provides can be achieved on, specific embodiment of the present utility model does not repeat.This is, The three of security mechanism.

In specific embodiment of the present utility model one, microcontroller has been used critically detect and control, every Inside individual supply hub, infrared sensing switch, and each socket position are assembled with, is assembled with independent electromagnetic relay As switching on and off for control power supply.In the state of plug is not inserted into, all relays are all the states disconnected, are owned Supply hub in copper sheet all disconnected with power supply, be uncharged；It is internal infrared when inserting regular plug Inductive switch senses the insertion of plug, to microcontroller send signal, microcontroller according to receive signal and safety rule Then judged, it is determined that being after inserting regular plug, then relay corresponding to control is to turn on, there is provided power supply.Thus, pole The big security performance for improving the electrical source socket.

It refer to Fig. 8, a kind of three-dimensional assembly diagram of the embodiment two of electrical source socket of the utility model.Specifically In embodiment two, the electrical source socket includes multiple socket positions, as illustrated, in embodiment two, we will With 4 socket positions, each socket position is illustrated exemplified by 5 mouthfuls of sockets.It is the same as those described above, wherein each 5 mouthfuls of sockets include one Individual Three-hole socket and two spring hole scokets.Present embodiment two by with include the power outlet of Safe control switch 24 fill Example is set to illustrate.As it was previously stated, then each socket position needs 5 pairs of infrared sensing switch, one shares 4 socket positions, then micro- Controller 27 needs to control 20 pairs of infrared sensing switch altogether.

The socket of other digits, it can be deduced according to the principle of the design of the concrete mode two.

Continuing with reference to Fig. 9, a kind of microcontroller control of the embodiment two of electrical source socket of the utility model The circuit theory diagrams of infrared sensing switch and relay processed.

The mode that embodiment two employs matrix arrangement and scanned one by one is entered to some infrared sensing switch 21 Row control.Because quantity is various, description for convenience illustrates, in the specific embodiment two, still needs to each infrared transmitting tube 211st, infrared receiving tube 212, relay 26 are numbered.

Specifically, the numbering of infrared transmitting tube 211 is followed successively by：D1-1, D1-2, D2-1, D2-2, D3-1, D3-2 ... D10-1, D10-2, wherein, D1-1 and D1-2 are in a socket, and D2-1 and D2-2 are in a socket, by that analogy, Until D10-1 and D10-2 is in a socket.Wherein, two infrared transmitting tube compositions being connected in parallel in the same direction are one group infrared Transmitting tube, such as D1-1, D1-2 are connected in parallel composition D1 group infrared transmitting tubes in the same direction, the like, D10-1 and D10-2 are in the same direction simultaneously Connection connection composition D10 group infrared transmitting tubes.Some infrared transmitting tubes form infrared transmitting tube matrix.

The numbering of infrared receiving tube 212 is followed successively by：Q1-1, Q1-2, Q2-1, Q2-2, Q3-1, Q3-2 ... Q10-1, Q10- 2, wherein, Q1-1 and D1-1 is a pair of infrared sensing switch 21, is provided in a sleeve 23；Q1-2 and D1-2 is one Right, Q2-1 and D2-1 is a pair, by that analogy, until Q10-2 and D10-2 is a pair.Some infrared receiving tube compositions are infrared Reception pipe matrix.

Each socket corresponds to a relay 26 respectively, then 8 relays, relay 26 are needed in present embodiment two Numbering be followed successively by K1, K2, K3 ... K8.Each relay K1, K2, K3 ... K8 correspond to controlling switch E1, an E2 respectively, E3……E8.Some controlling switches constitute controlling switch matrix.Controlling switch E1, E2, E3 ... the E8 of relay 26 with Mapping relations between infrared receiving tube Q1-1, Q1-2, Q2-1, Q2-2, Q3-1, Q3-2 ... Q10-1, Q10-2, can basis The actual state of circuit is preset in microcontroller 27.

Microcontroller 27 then controls above-mentioned infrared induction to open using N number of (N is greater than the natural number equal to 2) control output end Close.Each control output end is connected in parallel two groups of infrared sensing switch between other N-1 control output end respectively, and It is reverse between this two groups of infrared transmitting tubes consequently, it is possible to which N number of control output end can essentially control N* (N-1) groups infrared Inductive switch, i.e. 2N* (N-1) individual infrared sensing switch.

Such as：N is equal to 4, then at most can control 24 infrared sensing switch.And in present embodiment two, then use 4 control output end P1.0, P1.1, P1.2, P1.3 control 10 groups of infrared sensing switch.

On the basis of the above, if being further added by a control output end, N* (N+1) group switches can be controlled, you can more controls 2N groups switch processed.And one group of the controlling switch of a relay i.e. only electronic switch.Therefore, in present embodiment two Due to there are 8 relays, on the premise of above-mentioned infrared sensing switch matrix, increase an output control terminal P1.4 more. The N+1 defeated ends control two relay switches, the two relay switches with the 1st to n-th control output end respectively It is Opposite direction connection in parallel, and both positive and negative polarity is in opposite direction.As connected two controlling switches E1 and E5 between P1.4 and P1.0, when P1.4 high level, during P1.0 low levels, E1 conductings；On the contrary then E5 is turned on；Similarly, in parallel between P1.4 and P1.1 and Opposite direction connection E2 and E6；In parallel and Opposite direction connection E3 and E7 between P1.4 and P1.2；In parallel and Opposite direction connection E4 between P1.4 and P1.3 And E8.It is specific as shown in Figure 9.

It follows that each control output end can be connected in parallel two groups between other N-1 control output end respectively Reverse infrared transmitting tube, either two reverse controlling switches or mutually opposing infrared sensing switch and one Controlling switch.

It is understood that in above-mentioned matrix, infrared transmitting tube Q1-1 to Q10-2 distributing order and relay Controlling switch K1 to K8 distributing order, above-mentioned embodiment two have been merely given as one of which, and in fact, its order It is that can arbitrarily be arranged in the matrix according to the demand of circuit designers.Only need to ensure, set in microcontroller 27 Mapping relations and actual circuit between infrared sensing switch Q and controlling switch E are consistent.

During work, microcontroller 27 drives the infrared transmitting tube in infrared emission matrix D successively by way of scanning 211, only driving one of which infrared transmitting tube sends infrared ray every time.And the controlling switch E1 to E8 of relay, then be The control output end corresponding to control after judging of microcontroller 27 is connected.

It refer to the pulse schematic diagram of the control output end of the microcontroller 27 shown in Figure 10.Specifically, as first driven D1 Group infrared transmitting tube D1-1 and D1-2 light, send infrared light, now the infrared transmitting tube of other D2~D10 groups all in OFF state.When infrared transmitting tube D1-1 and D1-2 is lighted, if in sleeve corresponding with D1-2 with infrared transmitting tube D1-1 There is no object insertion, then infrared receiving tube Q1-1 and Q1-2 is both turned on, and two inputs P1.5 and P1.6 of microcontroller 27 are It is low level；If object, such as plug are inserted simultaneously in infrared transmitting tube D1-1 sleeves corresponding with D1-2, then microcontroller 27 two inputs P1.5 and P1.6 are high level, now, if microcontroller 27 is according to infrared receiving tube Q1-1 and Q1- 2 state and/or corresponding security mechanism, it is determined that determining there is plug insertion in socket corresponding to D1 group infrared transmitting tubes, then drive Relay K1 conductings corresponding to dynamic D1 group infrared transmitting tubes, i.e., as described in Figure 10, P1.4 output high level, P.10 export low electricity Flat, P1.1, P1.2 and P1.3 are arranged to high-impedance state output, and dotted portion is expressed as high-impedance state output in Figure 10, then controls E1 conductings are switched, so as to which relay K1 switches on power, socket can be with power taking corresponding to relay K1.

As described above, microcontroller 27 is lighted in next Timing driver D2 group infrared transmitting tube D2-1 and D2-2, equally , only when being inserted with object simultaneously in sleeve corresponding to this group of infrared transmitting tube, microcontroller 27 can just drive the infrared hairs of D2 Penetrate relay 26 corresponding to pipe to turn on, carry out power taking.

So order driving D3 group infrared transmitting tubes, D4 group infrared transmitting tubes, directly by every group of infrared transmitting tube in circuit And controlling switch all drives unlatching once.Then, that goes round and begins again drives since D1 group infrared transmitting tubes again.

In specific embodiment of the present utility model two, the electrical source socket possesses multiple socket positions, and required is red Outer inductive switch is more, to save the output end of microcontroller and reducing the wiring of circuit board, is arranged using matrix form infrared Emission switch, and with the mode scanned one by one, successively and monitor full time whether have plug insertion in each socket, only Having when it is determined that there is plug insertion, can just connect the power supply of corresponding jack.It is possible thereby to less microprocessor control output Can is held to control more infrared sensing switch, and the microcontroller that control output end is less, price are also relatively cheap, simultaneously Also the wiring of circuit board can be greatly reduced, reduce the area of circuit board, so as on the premise of product safety performance is ensured, Product cost is saved, reduces small product size.

In the utility model embodiment two, when there are multiple socket positions, the connected mode of matrix form is employed, by One microcontroller 27 controls the conducting and shut-off of the infrared sensing switch and relay in socket all on socket device, 4 infrared sensing switch or 2 relay switches, each control of microcontroller 27 can be controlled between each two control output end The regular high or low level of output of output end so that the infrared induction that the microcontroller can be lighted in each socket one by one is opened Close, i.e. the infrared sensing switch in each socket is lighted in a manner of scanning.And according to the state of infrared sensing switch and/or Other security mechanisms, it is determined whether relay switch corresponding to conducting.Wherein, the safe machine mentioned in present embodiment two System is identical with embodiment one, just no longer repeats one by one herein.

It refer to Figure 11, a kind of schematic block circuit diagram of the embodiment three of electrical source socket of the utility model.
