Description

The device of automatic sensing polarity of battery

Technical field

The present invention relates to electrical category, particularly a kind of device of automatic sensing polarity of battery.

Background technology

As shown in Figure 1, the configuration of general normal its electrical contact of charger A A1 is fixed, and positive contact that circuit extended in this charger A and negative contacts also are fixing contact, when desiring to be inserted in the different charger A of positive and negative joint configuration as its battery, this charger A also can't do the action of a charging in battery, even can cause the battery damage; Again, because of the position of battery A2 not of uniform size and its electrical contact A1 neither identical with distance, the battery A2 of single correspondence and the single charger A of form only can arrange in pairs or groups to such an extent as to can't reach the device that multiple battery charges of can arranging in pairs or groups with a charger A, need be improved.

Summary of the invention

The object of the present invention is to provide a kind of device of automatic sensing polarity of battery, solved the polarity that charger commonly used can't be detected battery, and can't reach with charger collocation multiple battery problem such as charge.

Technical scheme of the present invention is: a kind of device of automatic sensing polarity of battery comprises: two above sense terminals, and array is corresponding to detecting unit, positive voltage onunit and the negative voltage onunit of each sense terminal; Wherein, these two above sense terminal any two ends all can be connected with the battery conductive unit, when this plural number sense terminal any two ends is connected in anode and negative pole, a group or more detecting unit can be detected wherein, and an end is a positive voltage, and driving positive voltage onunit conducting, simultaneously, a group or more detecting unit can be detected wherein, and the other end is a negative voltage, and drive the conducting of negative voltage onunit, make electric current by the positive voltage onunit, flow back to through the negative voltage onunit, form a complete loop.

The invention has the advantages that: the pin of battery is connected when charger, but the polarity of charger Auto-Sensing battery; The power supply supply status of charger pin is decided by the position that connects of battery; Only need connect the pin of charger, be not limited to that the size of battery or connecting point position are different with distance all to charge; Significantly promote the compatibility of charger and battery, practical.

Embodiment

Shown in accompanying drawing 2 and accompanying drawing 3, circuit for detecting C of the present invention includes sense terminal D, detecting unit E, positive voltage onunit F, negative voltage onunit G constitute; Wherein, battery conductive unit H is connected in the sense terminal D of circuit for detecting C, when this sense terminal D is connected to battery B1 positive pole, the detecting unit E detecting that has a group or more is positive voltage, and drive positive voltage onunit F conducting, and charging device B positive pole is delivered to sense terminal D and communicate with battery B1 positive pole, and when corresponding another sense terminal D is connected to battery B1 negative pole, all the other are detectd unit E and are judged as negative voltage, and drive negative voltage onunit G conducting, communicate with battery B1 negative pole and charging device B negative pole is delivered to sense terminal D, make it form a complete charge circuit, and make charging device B begin battery B1 is charged.

As shown in Figures 3 to 5, the sense terminal D of circuit for detecting C is connected in battery conductive unit H, and only need the positive terminal H1 of its battery conductive unit H and any two ends that negative pole end H2 is connected to sense terminal D, this circuit for detecting C promptly forms a complete charge circuit.

Wherein, charger I can use two or more sense terminal D joints, it can cooperate battery B1 not of uniform size, and the position of matching battery conductive unit H and distance difference, to reach all charging contacts that to connect in battery B1, make charger I cooperate multiple battery B1 all can correctly find out positive terminal H1 and the negative pole end H2 of battery conductive unit H.

Be connected to the positive terminal H1 of battery conductive unit H as sense terminal A point D1, positive voltage is detected and be output as to this positive potential then via detecting unit E, and make positive voltage onunit F conducting, its positive voltage onunit F then with the anodal conducting of charging device B to sense terminal A point D1, and charging device B positive pole communicated in the positive terminal H1 of battery conductive unit H, be connected to the negative pole end H2 of battery conductive unit H in addition corresponding to sense terminal B point D2, negative voltage is detected and be output as to this negative potential then via detecting unit E, and make negative voltage onunit G conducting, its negative voltage onunit G then with the conducting of charging device B negative pole to sense terminal B point D2, and its charging device B negative pole communicated in the negative pole end H2 of battery conductive unit H, begin the action that battery B1 is charged to make charging device B.
