Abstract
A polar-free charger pertains to a charging device, consisting of a battery cabin 1 and a charging circuit 3. The positive terminal and the negative terminal of the battery cabin 1 are respectively connected on one end of a bridge-type rectifier circuit 2 and the other end of the bridge-type rectifier circuit 2 is respectively connected on the positive terminal and the negative terminal of the charging circuit 3. The battery cabin of the charger has no polar difference, so the battery can be arbitrarily inserted without checking the polarity of the battery, which greatly facilitates the use by just putting inside particularly in travel and on the middle way.
Description
Technical field
The utility model relates to a kind of charging device, particularly a kind of polarity charger of exempting from.
Technical background
Charger replenishes the electric power that uses battery and plays a good role, but the charger that existing market is used all has the requirement of polarity, and wrong just the infringement to charger and battery is all very big, makes people not have half-hearted checking when charging, is very much inconvenience.
Summary of the invention
The purpose of this utility model is to check the deficiencies such as polarity of battery at above-mentioned charging, proposes a kind of polarity charger of exempting from.It need not check the polarity of battery, puts into and can use.
The purpose of this utility model is achieved in that a kind of polarity charger of exempting from, form by battery compartment, charging circuit, the two positive and negative bridge-type streams that extremely are connected to of described battery compartment are put in order on the end of circuit, and the other end of bridge rectifier is connected to the positive and negative extreme of charging circuit.
The utility model has the advantages that: no positive-negative polarity difference in the battery compartment of charger, need not to check the polarity of battery and charger, battery can insert arbitrarily at battery compartment, particularly in tourism, the other places on the way in, put into and get final product, made things convenient for use.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model
Among the figure, battery compartment 1, bridge rectifier 2, charging circuit 3.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of polarity charger of exempting from of present embodiment is made up of battery compartment 1, charging circuit 3, and present embodiment is applied to the common charger in market, but single battery, but also multiple batteries can be battery No. one, also can be the battery of other models.A positive and negative end that extremely is connected to bridge rectifier 2 of described battery compartment 1, the other end of bridge rectifier 2 is connected to the positive and negative extreme of charging circuit 3, add bridge rectifier 2 between battery compartment 1 and charging circuit 3, bridge rectifier 2 two ends can arbitrarily connect.Bridge rectifier 2 is optimum circuits of transferring polarity, and the electronic component integrated level is very high, and a bridge rectifier 2 is very little.For directly assigning into battery compartment, finishes for 1 li single battery in the present embodiment.Mostly being parallel form according to the existing market charger, can be that a plurality of bridge rectifier 2 is integrated to multiple batteries storehouse 1.
Claims (1)
1. exempt from the polarity charger for one kind, form by battery compartment (1), charging circuit (3), it is characterized in that: two positive and negative ends that extremely are connected to bridge rectifier (2) of described battery compartment (1), the other end of bridge rectifier (2) are connected to the positive and negative extreme of charging circuit (3).
