Description

Charger

[technical field]

The utility model is relevant a kind of charger, refers in particular to a kind of charger that can be the cell panel charging of notebook computer.

[background technology]

At present, notebook computer adopts cell panel to come for it provides non-firm power mostly, and cell panel is plugged in the notebook computer in use, then extracts out in notebook computer during power shortage and is its charging by charger.Because the cell panel structure difference that different notebook computer producer is adopted, so it is also inequality for charger that cell panel disposes.The notebook computer of same producer is because the model difference, the cell panel that it adopted also might be different, even the notebook computer of the same model of same producer also may adopt different cell panels, this is because notebook computer is sold to different countries and regions usually, because the mains voltage difference of these countries and regions, make that producer must be at the different cell panel of above-mentioned different countries and regions design, thereby the notebook computer that causes occurring the same model of same producer adopts the situation of different cell panels.If same producer all disposes corresponding charger respectively for each required cell panel of notebook computer of its production, the inevitable manufacturing cost that increases notebook computer greatly, thus its selling price is also further improved.

Though, now also having can be for the charger of different cell panel chargings, as United States Patent (USP) the 5th, 689, No. 171, D358, No. 813, D328, No. 889, D402, No. 957 and No. 390545 case of TaiWan, China patent announcement disclose, and also there is such cell panel charger of release in NEC Corporation (relevant information sees also in addition Http:// www.alancomputech.com/necnotbatcha.htmlShown in).But these chargers are normally comparatively close at structure, the cell panel that the charge port position is roughly the same and designing, and differ bigger for some structures, charge port position cell panel inequality but can't satisfy its charging requirement.As consult shown in Figure 1, first cell panel 8 roughly is square, its charge port 81 is positioned at this cell panel one side edge, see also shown in Figure 2 again, second cell panel 9 is the strip configuration, and its charge port 91 is positioned at this front side, cell panel 9 bottom, and the cell panel of its both sides bottom is protruding with a pair of cylindrical projection 92 downwards, in addition, the rear side that is positioned at this cell panel bottom is provided with a clasp 93.Obviously, first cell panel 8 shown in Figure 1 is all bigger with the structure and the charge port position difference of the cell panel of second cell panel, 9 these two kinds of existing notebook computers shown in Figure 2, disposes different chargers respectively and need expend bigger cost.

In view of this, be necessary really existing this class charger is improved to overcome described defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of charger, and it can be the structure cell panel charging all different with the charge port position, thereby reduces manufacturing cost greatly.

For achieving the above object, the utility model adopts following technical scheme: a kind of charger, can be connected with power supply device and be first and second cell panel charging of different structure, it comprises cradle, be arranged on first connector that can dock with above-mentioned first cell panel and second cell panel respectively in the cradle and second connector and with the first circuit board and the second circuit board of first connector and the electric connection of second electric connector; Wherein cradle comprises pedestal and is installed in lid on the pedestal, first connector has first insulating body and first conducting terminal, each first conducting terminal comprises first contact site that can electrically connect with first cell panel and first weld part that can weld mutually with first circuit board, second connector has second insulating body and second conducting terminal, and each second conducting terminal comprises second contact site that can electrically connect with second cell panel and second weld part that can weld mutually with second circuit board; The roughly stepped configuration of the lid of above-mentioned cradle, the boss that it includes platform and is extended by platform one end, a side along continuous straight runs that closes on platform at boss offers first socket that contains described first connector and can peg graft for first cell panel, vertically offers second socket that contains described second connector and can peg graft for second cell panel at the upper surface of platform.

Compared with prior art, horizontally disposed first socket of the cradle of the utility model charger can be positioned at the cell panel grafting charging of side for charge port, and the cell panel bottom its vertical second socket that is provided with can be positioned at for charge port is pegged graft and charged.By this structure, this charger can be structure all has the different cell panels than big-difference to charge with charge position, and need not to dispose charger separately at each cell panel, thereby has reduced the cost of manufacturing.
