Main body 25 be shaped as rectangle, it comprises upper cover body 251, lower cover 253, circuit unit 256, rotary switch 257, the second driving-belt 258 and pair of conductive part 259.Circuit unit 256, rotary switch 257, the second driving-belt 258 and pair of conductive part 259 are all contained in lower cover 253, and upper cover body 251 is for sealing lower cover 253.Rotary switch 257 is installed on circuit unit 256.The second driving-belt 258 is set on rotary switch 257, and its two ends are fixedly connected with away from one end of plug 21 with two wires 23 respectively.One end of pair of conductive part 259 is installed on respectively on circuit unit 256, and the other end of pair of conductive part 259 is set in respectively on two wires 23.
One end of lower cover 253 is equiped with inserting groove 2531, and its other end is connected with sheath 214.Inserting groove 2531 is for socket power.Circuit unit 256 comprises input 2562, output 2565 and transformer (not shown), and input 2562 is electrically connected with power supply, and output 2565 is for exporting power supply main body 25.AC power flows to the input 2562 of circuit unit 256, then the transformer of flowing through, and AC power changes DC power supply into, and DC power supply flows into the output 2565 of circuit unit 256, thereby the power supply that output 2565 flows out is DC power supply.
Rotary switch 257 is installed on the input 2562 of circuit unit 256, for controlling the conducting of power supply and circuit unit 256 and closing.The second driving-belt 258 is sheathed on rotary switch 257, and its two ends are connected with two wires 23 respectively.The shape of pair of conductive part 259 is identical, and its shape is roughly square.One end of pair of conductive part 259 is movably set in respectively on two wires 23, and the other end of this pair of conductive part 259 is fixedly connected on respectively on the output 2565 of circuit unit 256, for power supply being sent to respectively to two wires 23.
Assembling power adapter 20, first by the first driving-belt 213, the first conducting strip 215, the second conducting strip 217 and exit on the body 212 of pedestal 211 that pin 218 is installed in respectively plug 21; One end of the first conducting strip 215 and the second conducting strip 217 is set in respectively to one end of two wires 23, one end of two wires 23 is fixedly connected with the two ends of the first driving-belt 213 respectively; Two wires 23 are inserted in sheath 214, and the other end of two wires 23 is fixedly connected with the second driving-belt 258 respectively, the first driving-belt 213, two wires 23 and the second driving-belt 258 are connected to form a closed circle between two thus; Then circuit unit 256 and rotary switch 257 are installed in respectively in lower cover 253, the second driving-belt 258 is set on rotary switch 257; One end of pair of conductive part 259 is electrically connected with two wires 23 respectively, and the other end of this pair of conductive part 259 is fixedly connected on the output of circuit unit 256; Finally upper cover body 251 is sealed to lower cover 253.In the time that the first driving-belt 213 rotates, it drives the second driving-belt 258 to rotate, the second driving-belt 258 driven rotary switches 257, thus control the conducting of power supply and circuit unit 256 and close.
When use, see also Fig. 7 and Fig. 8, the plug of power supply adaptor 20 21 is inserted in the slot 16 5 of power supply plug-in connection 10 of electronic installation 100, when plug 21 enters behind the grafting space of plug connector 16, the body 212 of plug 21 produces squeezing action power to the second drive 145, the second drive 145 moves towards switch module 14, and then compression elastic piece 143.Continue to insert, when the position of the first stopper slot 2123 of plug 21 and the position of the second drive 145 are when corresponding, the body 212 of plug 21 disappears to the extruding force of the second drive 145, and elastic component 143 recovers deformation, and the second drive 145 restores under the active force of elastic component 143.Now, the second drive 145 parts are accommodated in the first stopper slot 2123 of plug 21, and the first driving-belt 213 is set on the second drive 145, and in present embodiment, the first driving-belt 213 is meshed with the second drive 145.Meanwhile, the first conducting strip 215 in plug 21 contacts with the conductive part 1631 of the first electrode 163 of plug connector 16, and the second conducting strip 217 in plug 21 contacts with the conductive part 1641 of the second electrode 164 of plug connector 16.
Button 148 is pressed to ON mark end, button 148 drives button gear 147 to rotate by button power transmission shaft 146, because button gear 147 engages with the first drive 144, thereby button gear 147 drives the first drive 144 to rotate, the first drive 144 drives the second drive 145 to rotate by gearing shaft 142.Because the second drive 145 engages with the first driving-belt 213, so the second drive 145 drives the first driving-belt 213 to rotate, because the first driving-belt 213 and wire 23 and the second driving-belt 258 are in turn connected to form a closed circle, thus, the second driving-belt 258 rotates.And then the second driving-belt 258 driven rotary switches 257 rotate to conducting state.
While closing, button 148 is pressed to OFF mark end, button 148 drives button gear 147 to rotate recovery by button power transmission shaft 146, and then button gear 147 drives the first drive 144 to rotate recovery, the first drive 144 drives the second drive 145 rotations to restore by gearing shaft 142, the second drive 145 drives wire 23 and the second driving-belt 258 to rotate recovery by the first driving-belt 213, and final the second driving-belt 258 driven rotary switches 257 rotate to initial closed state.After closing, the pin 218 that exits of plug 21 is advanced towards slot 16 5, exit after pin 218 enters grafting space the second drive 145 is produced to squeezing action power, thereby the second drive 145 is moved towards switch module 14, and then first driving-belt 213 remove and the engagement of the second drive 145, plug 21 can be extracted from slot 16 5.Now, the elastic component 219 in plug 21 is housed in the second slot 2127, prevents from exiting pin 218 return back in the 3rd stopper slot 2125 with this.
Present embodiment arranges rotary switch 257 by the input 2562 of the circuit unit 256 at power supply adaptor 20, on rotary switch 257, sheathed the second driving-belt 258, the second driving-belts 258 are connected to form a closed circle through wire 23 and the first driving-belt 213; Power supply plug-in connection 10 is set in electronic installation 100, plug 21 makes the first driving-belt 213 engage with the second drive 145 while inserting in power supply plug-in connection 10, recycling button 148 drives button gear 147, the first drive 144 and the second drive 145 to move successively, and then drive the second driving-belt 258 to rotate, thereby control the conducting of rotary switch 257 and close.The power supply of main body 25 that thus can powered-down adapter 20 by the button 148 on the power supply plug-in connection 10 of electronic installation 100, thus energy consumption reduced, and operation is convenient; Due to after plug 21 inserts in the slot 16 5 of electronic installation 100, the first driving-belt 213 is meshed with the second drive 145, thereby can avoid plug 21 to pitch; Also to make to pull up plug 21 more easy for the pin 218 that exits on plug 21.
Be appreciated that, the second end face 1452 of the second drive 145 also can be plane, the sidewall that simultaneously makes the second end face 1452 of relative the second drive of slot 16 5 is inclined-plane, as long as can make the second end face 1452 of the second drive 145 and the grafting space that the sidewall of slot 16 5 forms diminish gradually along direction of insertion along the axial width of the second drive 145.Even, grafting space width is constant, and the thickness of plug 21 is diminished gradually along direction of insertion, as long as can compress or discharge elastic component 143 in plug 21 plug processes.
Button power transmission shaft 146 can omit, and button 148 is fixedly connected with button gear 147, when External Force Acting is during in button 148, can drive equally button gear 147 telemechanicals.
In addition, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection range that all should belong to patent claim of the present invention the with distortion.
