Description

Charger

Technical field

The utility model relates to a kind of charger, particularly relates to a kind of charger that digital products such as mobile phone, MP3, MP4 or digital camera are charged.

Background technology

Disclose among the disclosed Chinese patent bulletin CN2403133Y on October 25th, 2000 a kind of " inserting the wall type charger for mobile phone ", mainly comprise the insertion slot that is opened in the top, and the plug of being located at a side wall surface, wherein this insertion slot is an inner concavity, inside is available puts in order to do charge or discharge for mobile phone or battery, flat the establishing of this plug protrudes from the side wall surface, and this charger body inside is provided with electronic circuit; Charger (portable round) directly is inserted in the socket on the wall and can locatees and use, exempt puzzlement and inconvenience that the known charge device need extend electric wire.Though this charger can be exempted the puzzlement of charging wire, but its shortcoming is that the insertion slot of inner concavity is corresponding one by one with mobile phone model, even the mobile phone of other model and insertion slot match, but may cause and to use because the charging jack is positioned at the position difference of mobile phone bottom, so the mobile phone of different model can not shared same charger, causes the waste of resource; Volume is less and can insert the mobile phone of insertion slot, also because be difficult to make the charging jack on the mobile phone to aim at the charging plug of insertion slot bottom and use difficulty.

Existing another kind of charger for mobile phone is drawn well and is filled, it is to go up at cradle (shell) slot that matches with the mobile phone bottom is set, in slot, be provided with mobile phone on the corresponding electrode slice of charging contact, between cradle and mains supply, be connected with power line, need not to be connected between mobile phone and the cradle with flexible cord, during charging, mobile phone is inserted directly the charging contact that can make in the slot of cradle in the mobile phone contacts with electrode in the slot and to cell-phone charging, slot on its cradle equally must be corresponding one by one with mobile phone model, and the mobile phone between the different model can not shared same charger; The mobile phone bottom is less than the mobile phone of slot, even can insert slot, but because the gap is bigger between mobile phone bottom and the slot, the one, be difficult to make electrode in the charging contact alignment of mobile phone to cause and use inconvenience, the 2nd, vibrate a little and will make the mobile phone displacement and cause loose contact.

Above-mentioned charger also can be described as power supply adaptor.

Summary of the invention

The utility model purpose be for solve can not be shared between the product different to be charged that exists in the existing charger problem, and provide a kind of digital product charger easy to use, making between the product to be charged of most of different models can shared charger, and product to be charged can be placed in the charger easily, does not need in addition between charger and product to be charged cord to be set again and is connected.

The purpose of this utility model is achieved in that a kind of charger, establish the wiring board of charging circuit in comprising, shell and conversion head, conversion head upper end is provided with the charging plug that the charging jack with product to be charged matches, described conversion head bottom be provided with two rigidity that are electrically connected with two electrical contacts on the described charging plug respectively the input electric contact point (described used as electric contacts in the charging jack of product to be charged in electric contact point electrically contact), described shell is provided with the containing cavity that opening makes progress and can hold product to be charged, be fixedly provided with the output electrode of two rigidity that are electrically connected with the dc output end of described charging circuit respectively in the bottom of described containing cavity, arrange trend and front and back about described two output electrodes; Arrange before and after two of described conversion head bottom input electric contact points and two input electric contact point opposed inside are outwards opened (under product action of gravity to be charged) downwards and pushed down the outside of described two output electrodes, the contact position of described output electrode and this input electric contact point is a cylinder; During product swing to be charged, the circumferencial direction along cylinder slides described two input electric contact points on two cylinder surfaces of two output electrodes on outside open inclined-planes downwards, and makes two input electric contact points keep respectively electrically contacting with described two output electrodes.

The inboard of described input electric contact point is the inclined-plane.The below that the inboard outside flare up arc surface downwards of perhaps described input electric contact point and the center of circle are positioned at this arc surface, the central axes of two arc surfaces.

Owing to adopted technical scheme described in the utility model, after only the charging plug on the conversion head need being inserted the charging jack of product to be charged when the user uses, drop in the containing cavity of shell more together, the inboard that makes two of conversion head bottom input electric contact points respectively cross-pressures on the cylinder of described output electrode, even product to be charged was all around swung two input electric contact points were kept and the contacting of two output electrodes this moment; And the output electrode of described two rigidity is to be arranged on shell containing cavity bottom regularly, the electric wire that is connected that is connected between the positive and negative dc output end of two output electrodes and described charging circuit can not move because of place product to be charged in containing cavity, has improved connection reliability and life-span between this connection electric wire and the output electrode.For having the same transitions head but charging jack position different product to be charged can use same charger, only need to change a slight conversion head between the product to be charged of different charging jacks (the just charging plug difference on the conversion head) and get final product even have; Need not to be provided with cord between charger and product to be charged is connected; It is not only convenient to use, and same charger can charge to different product, has saved social resources.
