The desk type charger that is used for Samsung A288 and N288 mobile phone
The utility model relates to a kind of charger, relate in particular to a kind of can be simultaneously to the desk type charger of mobile phone and polytype battery charge thereof.
Existing Samsung charger for mobile phone can only can not charge by compatible mobile phone and battery thereof to multiple model to a kind of mobile phone and battery charge of model, and this obviously is inconvenient to user, particularly mobile phone distributors.
The purpose of this utility model is to provide a kind of compatible Samsung A288 and N288 mobile phone and desk type charger thick, thin battery thereof simultaneously according to mobile phone distributors and user's actual needs.
The purpose of this utility model can realize by adopting following technical measures, design a kind of desk type charger that is used for Samsung A288 and N288 mobile phone, comprise: shell, place the charging circuit of shell inner cavity and draw the charging adapter that is connected to the mobile phone groove from the power output end of charging circuit, it is characterized in that: it is characterized in that: also comprise one case surface and can be thick with Samsung A288 or N288, battery case that the thin battery shape is suitable, two electric contacts of this battery case are connected with the power output end of charging circuit.Like this, this charger just can charge by compatible thick, thin reserve battery to Samsung A288 and N288 mobile phone and an one A288 or N288 type simultaneously.
The drawing of accompanying drawing is described as follows:
Fig. 1 is overlooking and vertical cross section of the utility model desk type charger of being used for Samsung A288 and N288 mobile phone;
Fig. 2 is the shape and structure schematic diagram of battery hardware;
Fig. 3 is the basic circuit diagram of charging circuit.
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the desk type charger that the utility model is used for Samsung A288 and N288 mobile phone comprises: shell 1, place the charging circuit 2 of shell 1 inner chamber and draw the charging adapter 4 that is connected to mobile phone groove 3 from the power output end of charging circuit 2, also comprise one on shell 1 surface and can be thick with Samsung A288 or N288, battery case 5 that the thin battery shape is suitable, two electric contacts of this battery case 5 are connected with the power output end of charging circuit 2.Described battery case 5 is for being positioned at the spill fluting 51 of shell 1 concave surface, and a side inwall on fluting 51 long limits is provided with two circular arc location bones 52, is used for fixing battery of mobile phone to make it not rock, and contacts with battery five metals assembly 6 well to guarantee the battery positive and negative electrode; The opposite side inwall is provided with rectangle convex surface 53, also is to be used for battery in place, thereby guarantees that the charging contact is good; Be provided with a pair of aperture 54 that is communicated with shell 1 inner chamber in the described rectangle convex surface 53, battery five metals assembly 6 places described aperture 54, and battery case 5 is electrically connected with charging circuit 2 by this battery five metals assembly 6.The basic circuit diagram of charging circuit 2 is a prior art as shown in Figure 3.
Described shell 1 has circular head and near the body portion of rectangle; Mobile phone groove 3 is positioned at head, and battery case 5 is positioned at body portion, and mobile phone groove 3 is vertical placement with battery case 5.
Described battery five metals assembly 6 is identical and have appropriate flexible copper sheet hardware for a pair of shape, and three pin that stagger mutually 61 are arranged at the bottom of described hardware, and this pin 61 is clamped on the circuit board, and bow 62 is arranged near the battery charge contact on its top; 61, one on the pin of two hardwares is welded on the K node of charging circuit 2, and another is welded on the earth terminal of charging circuit 2.
The diode indicator light of described charging circuit 2 draws the head upper surface position intermediate of receiving shell 1.
Compared with prior art, the utility model desk type charger of being used for Samsung A288 and N288 mobile phone has following advantage: can be compatible Samsung A288 and N288 mobile phone and an one thick battery of A288 type or thin battery or the thick battery of N288 type or thin battery be charged simultaneously.
