Abstract
The utility model discloses an electrodeless mobile phone universal charger which aims at solving the technical problems of improving the limitation of the fixed point output of the positive and negative poles of the mobile phone battery charger. The following technical proposal is adopted: four diodes are additionally arranged between the external power connector and the positive and negative pole contacts. The single conduction performance of the diode enables two diodes to be connected in the circuit to make the circuit on and can ensure the uniformity of charging electrode (output) no matter right connected or reverse connected, thereby, the electrodeless mobile phone universal charger is convenient in use.
Description
One, technical field
The utility model belongs to battery charger for mobile phone, relates in particular to a kind of electrodeless omnipotent battery charger.
Two, technical background
The mobile phone people from live and work bring great convenience, extensive use along with mobile phone, comfort level requirement to battery charger for mobile phone is also more and more higher, and the battery charger for mobile phone of prior art has strict requirement to the polarity that is placed on battery of mobile phone to be charged wherein.When we use existing cell-phone charging, need the manual test electric power polarity, make " just " connect " just ", " bearing " connects " bearing ", and this way is not only pretty troublesome, particularly to specific groups such as the elderlys, and goes down to cause infringement to battery for a long time.
Three, technical scheme
The purpose of this utility model provides a kind of restriction that is not subjected to both positive and negative polarity when being convenient for people to charging mobile phone battery for people, and no matter how the polarity of power supply can both guarantee the charging polarity unanimity, makes the normal electrodeless mobile phone universal charger of charging political affairs.
For achieving the above object, main technical schemes of the present utility model: between external power supply plug and charger both positive and negative polarity contact, set up four diodes, wherein the negative pole of diode links to each other with the charger cathode contact, the positive pole of diode is linked to each other with the charger cathode contact, one the negative pole that will link to each other with the charger cathode contact with one positive pole in the diode that the charger cathode contact links to each other again in the diode links to each other with a binding post of attaching plug, will link to each other with a binding post of attaching plug with link to each other with the charger cathode contact negative pole of the another in the diode of the positive pole of another in the diode that the charger cathode contact links to each other.
The utility model compared with prior art, not only simple in structure, and utilize the unidirectional conduction property of diode, make and just connect reversal connection and all have two pieces of diodes to be connected on to power supply the time to make the charger circuit conducting in the circuit, make the polarity that when battery of mobile phone is charged, needn't carefully recognize charger, easy to use, cause damage because of the both positive and negative polarity reversal connection when effectively avoiding charging mobile phone battery.
The utility model is described in further detail below in conjunction with accompanying drawing.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 is the charger cathode contact, and 2 is the charger cathode contact, and 3,4,5,6 is diode, and 7,8 is the attaching plug binding post.
Five, embodiment
As shown in Figure 1, set up four diodes between external power supply joint in battery charger for mobile phone and the charger both positive and negative polarity contact, wherein the negative pole of diode 3,4 links to each other with charger cathode contact 1, the positive pole of diode 5,6 is linked to each other with charger cathode contact 2, the positive pole of diode 3 links to each other with a binding post 7 of attaching plug with the negative pole of diode 5, and the negative pole of the positive pole of diode 4 and diode 6 links to each other with the another binding post 8 of attaching plug.When binding post 7 connects positive pole, when binding post 8 connect negative pole, diode 3,5 was just connecing conducting, and diode 4,6 reversal connections end; When binding post 7 connects negative pole, when binding post 8 connect positive pole, diode 3,5 reversal connections ended, and diode 4,6 is just connecing turn-on power.
Claims (1)
1, a kind of electrodeless mobile phone universal charger, it comprises the charger pedestal, anode contact (1) and cathode contact (2) and external power supply plug, it is characterized in that: between external power connection and charger both positive and negative polarity contact, set up four diodes, wherein with diode (3,4) negative pole links to each other with charger cathode contact (1), with diode (5,6) positive pole links to each other with charger cathode contact (2), the positive pole of diode (3) links to each other with a binding post (7) of attaching plug with the negative pole of diode (5), and the negative pole of the positive pole of diode (4) and diode (6) links to each other with the another binding post (8) of attaching plug.
