Embodiment
For the ease of those skilled in the art will recognize that technical solutions of the utility model are described in further detail below in conjunction with specific embodiment and accompanying drawing.
As shown in Figure 1 and Figure 2, plug-changeable power supply described in the utility model comprises power supply unit unit 10 and interchangeable plug unit 40, the two is for dividing body structure, the configurable a plurality of interchangeable plug unit in power supply unit unit, power supply unit unit and the grafting of interchangeable plug unit.The difference of each interchangeable plug unit 40 is, the metallic plug 413 that is provided with on it.This metallic plug 413 can be two or more, can be set to flat or cylindric, square shape, also can be D font or other non-standard plugs, to adapt to the various power output socket in various countries.
In order to increase the versatility of power supply unit, on described power supply unit unit 10, establish the supply socket 32 that meets international standard, establish the attaching plug that meets international standard 43 that cooperates grafting with supply socket 32 on the interchangeable plug unit 40.Circuit in supply socket 32 and the power supply unit unit 10 is connected, metallic plug 413 and attaching plug 43 electrical connections.After pegging graft, power supply unit unit 10 and interchangeable plug unit 40 form a complete power supply unit.Because splicing interface all adopts supply socket and the plug that meets international standard, coupling is convenient, even under the situation that does not have interchangeable plug unit 40, also can use one to have supply socket (the IEC 60320-1 that meets international standard, C7) power plug wire, supply socket is inserted on the supply unit, forms a complete power supply unit and use.
Embodiment
Shown in Fig. 2,3, the wiring board 50, one that the power supply unit unit can specifically comprise loam cake 20, lower cover 30 and be located at inside, unit meets supply socket (the IEC 60320-1 of international standard, 68) 32, in the supply socket 32 2 cylindrical conductive pins 332 are arranged, conductive pin 332 is fixed in the socket bottom base 323, one end of this conductive pin 332 is inserted in the circular hole of metal terminal 331, tapering parts below the metal terminal 331 are inserted in the welding hole 501 on the wiring board 50 and by last soldering and connect, and form with circuit board 50 in the power supply unit unit to be electrically connected.The panel of lower cover 30 is provided with a groove shaped location notch 314, and the marginal position place of this location notch 314 also is provided with the wedge draw-in groove, this location notch 314 and buckle 322 corresponding are connected of wedge draw-in groove with supply socket 32 susceptor edges both sides.The supply output line is welded on the wiring board 50, and output line fixes by the buckle on the loam cake 20 205, covers loam cake 20 and lower cover 30, just becomes a complete power supply unit unit.
Described interchangeable plug unit 40, the one end is equipped with some dissimilar metallic plugs 413 that are applicable to country variant, the other end is provided with attaching plug (the IEC 60320-1 that meets international standard, C7) 43,2 cylindric conductive troughs 70 are arranged in this attaching plug 43, metallic plug 413 is connected by metal linking arm 71 with attaching plug inner cylinder dress conductive trough 70, establish location hole 721 on the metal linking arm 72, welding hole 722, be welded on 722 with metal material one end, the other end is welded on 421 attaching plug (the IEC 60320-1 of metallic plug 413 with international standard, C8) Nei tubular metallic object 75 is connected, also be provided with the buckle of edge protuberance on the interchangeable plug body 40, with attaching plug (IEC 60320-1, C7) 432 plug portions 41 with interchangeable plug body assemble and are electrically connected by welding hole 722 welding backs and metallic plug 413 formation, cover the involution lid 42 of interchangeable plug body, become a complete interchangeable plug unit.
When the attaching plug 432 on the interchangeable plug unit 40 is inserted into the supply socket 32 of power supply unit unit, cylindrical conductive pins 332 in the supply socket 32 are inserted into to form in the hole 752 of tubular metallic object of the cylindric conductive trough 75 in the attaching plug 432 and are electrically connected reliably, attaching plug 432 is embedded into the firm mechanical connection of formation in the supply socket 32, the buckle of attaching plug 432 edge protuberance is inserted in the groove shaped location notch 323 of supply socket 32 bottoms simultaneously, so just formed a complete power supply unit, changed different interchangeable plug body and just can adapt to the supply socket of country variant.Especially, use one to have supply socket (the IEC 60320-1 that meets international standard, C7) power plug wire when supply socket is inserted into supply socket on the supply body, also can be connected with the power supply unit body easily and forms a complete power supply unit;
When having only interchangeable plug body 40 to be inserted on the electrical network socket (not having the power supply unit body), because the cylindrical metal electric conductor 70 on the interchangeable plug body 40 in the plug is hidden in the cylindrical insulating material body of attaching plug 432, so human body can not touch the danger that electric conductor does not have electric shock, and is safer compared to prior art the utility model.
Need to prove; above-mentioned execution mode only is the preferable embodiment of the utility model; it can not be interpreted as restriction to the utility model protection range; do not breaking away under the utility model design prerequisite, any impartial the variation with modification that the utility model is done all belongs to protection range of the present utility model.
