A kind of structural representation that exchanges conversion DC circuit specific embodiment that a kind of multi-functional plate connector that Fig. 2 provides for the utility model has.
Referring to Fig. 2; On concrete the realization, said interchange conversion DC circuit can include ac input end T, from the voltage of this ac input end input AC AC220V; Said ac input end T is connected with a rectifier bridge, and said rectifier bridge is formed bridge circuit by diode D1, D2, D3, D4.
Said rectifier bridge is connected with the input of a switch transformer T301, and the output of said switch transformer T301 is connected with usb circuit (usb circuit is load circuit).
Referring to Fig. 2, on concrete the realization, said rectifier bridge is connected with the first input winding L 1 of said switch transformer T301, and the first output winding L 3 of said switch transformer T301 is connected, and the said first output winding L 3 is connected with usb circuit.
Has node A between the first input winding L 1 of said rectifier bridge and said switch transformer T301; Said node A connects resistance R 3, R2 respectively; Said resistance R 2 connects respectively with the first input winding L 1 and is in parallel, and said resistance R 2 meets the collector electrode C of triode Q1, and the base stage B of said triode Q1 is connecting resistance R3, triode Q2 and capacitor C 1 respectively; The emitter E of said triode Q1 is connecting resistance R3, R7 respectively; Said resistance R 3 ground connection, said resistance R 7 are joined the emitter E ground connection of said triode Q2 with base stage B, the voltage-stabiliser tube Z1 of said triode Q2 respectively.

Referring to Fig. 2; On concrete the realization; The alternating voltage of the utility model ac input end T input obtains pulsating dc voltage at node A place after the rectifier bridge rectification that D1 ~ D4 forms, this voltage one tunnel adds to the C utmost point of switching tube Q1 through the exit 1,2 of the first input winding L 1 of switch transformer T301; Another road adds to the B utmost point of Q1 through current-limiting resistance R3, for Q1 provides starting current.Q1 begins conducting; Its collector current in the first input winding L 1 of T301, produce exit 1 be just, the electromotive force of exit 2 for bearing; Through T301 coupling, in the second input winding L 2 of T301, induce exit 3 for just, exit 4 is negative electromotive force, this electromotive force is through R4; The be added to b utmost point of Q1 of C1 makes the rapid saturation conduction of Q1.The electric current of inductance can not suddenly change owing to flow through, and is positive electromotive force so in the first input winding L 1 of T301, produce exit 1 for negative, exit 2.Through the T301 coupling, in the second input winding L 2 of T301, induce exit 3 and be positive electromotive force for negative, exit 4, through R4, C1 makes Q1 get into cut-off state rapidly.Along with node A through the continuous charging of R3 to C1, Q1 begins conducting again, and then gets into the switch oscillatory regime of next round.Between the off period, T301 releases energy through D6 and load circuit thereof through the secondary first output winding L 3, obtains the needed charging voltage of USB interface of household electrical appliance such as mobile phone, MP3.
For circuit shown in Figure 2, voltage stabilizing circuit is by voltage-stabiliser tube Z1, and elements such as Q2 are formed.When the load reduction of USB interface or civil power raise, the B point voltage certainly will rise.When this voltage during greater than 5.6V, Z1 punctures, and Q2 ends Q1 in advance, and then makes switch power source output voltage be tending towards decline because of base stage B and the conducting rapidly of emitter E knot positively biased; Otherwise then control procedure is opposite, thereby makes T301 secondary output voltage basicly stable.
For circuit shown in Figure 2, protective circuit R1, R6 are current resistor.When the load of USB interface was overweight, the current potential between the collector and emitter of Q1 must increase, and the last pressure drop of R6 also increases thereupon.When this voltage during, Q2 saturation conduction greater than 0.7V, be equivalent to collector electrode C and the emitter E short circuit of Q2, Q1 ends because of base stage B dead electricity at once, reaches the purpose of overcurrent protection.For the first input winding L 1 of avoiding T301 between the off period induces spike high-voltage breakdown Q1, in the first input winding L, 1 parallel connection of T301 spike absorption resistance R2, to improve the switching characteristic of Q1.
When charging circuit was in zero load, the last no current of R8 flow through, and the emitter E of Q3 is equal basically with base stage B junction voltage, and Q3 ends, and LED2 (green light) goes out, and power supply indicator LED1 (red light) is bright; When charging, the pressure drop that charging current produces on R8 makes the conducting of Q3 positively biased, and LED2 is bright, and expression is charged.Along with battery constantly charges, its charging current reduces gradually, and the last pressure drop of R8 also reduces thereupon, and when the emitter E of Q3 and base stage B junction bias during less than 0.7V, Q3 ends, and LED2 extinguishes, and the expression electricity is full of.
Therefore; Through utilization the utility model; Can improve the socket cosmetic look, and can better protection supply household electrical appliance, can enlarge the usage space of product; The increase of new function certainly will will change the use limitation of existing product, will make product show its unique function in more field.
In sum; Compared with prior art, a kind of multi-functional plate connector that the utility model provides, its household electrical appliance such as mobile phone that can have for the user easily provide USB supply power mode; Make things convenient for daily use mobile phone of user etc. to have the household electrical appliance of USB interface; Offer convenience for user's life, help improving user's quality of the life, be of great practical significance.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
