Abstract
The utility model discloses a battery charger, comprising a case, a charging circuit and a control device arranged in the case and at least one battery jar arranged on the case. The battery jar includes a circular arc slot base. Both ends of the circular arc slot base are respectively connected with the upper end face and the lower end face of the battery jar. The upper end face is provided with an anode hole. An anode piece is arranged in the anode hole. The lower surface of the anode piece is higher than the lower hole plane of the anode hole. The lower end face is provided with a cathode hole. A cathode device passed through the cathode hole. The cathode device comprises a spring. The upper part of the spring is sheathed in a cathode cap. The cathode cap passes through the cathode hole. The case is connected with a power plug. The anode piece of the charger is a concealed anode piece. When directions of positive and negative poles of a battery is inversely positioned, the anode of the battery is contacted with the cathode of the charger, but the cathode of the battery can not be contacted with the anode piece of the charger, so the charging circuit can not be conducted. Therefore, The reverse charging of the battery is effectively prevented, the structure of the charger is briefer, and the carryis more convenient.
Description
Technical field
The utility model belongs to battery charger, is specifically related to a kind of charger of incorporate lithium ion cylinder type battery.
Background technology
Present widely used lithium ion cylinder type battery charger all is split type, and promptly the main body of charger is connected with attaching plug by connecting lead.The battery case of the existing lithium ion cylinder type of what is more important battery charger does not possess the function that counnter attack is filled, promptly when the both positive and negative polarity of battery after battery case is put back, the phenomenon of reverse battery charging will take place behind the power connection, like this safe in utilization with regard to the entail dangers to battery.
Summary of the invention
The purpose of this utility model is to provide a kind of charger that can prevent the lithium ion cylinder type battery of reverse battery charging, to address the above problem.
The technical solution of the utility model is: battery charger, and it comprises shell, establishes charging circuit and control device in the shell, establishes at least one battery case on the shell, described battery case comprises at the bottom of the arc-shaped slot that two ends connect upper surface, lower surface respectively at the bottom of the arc-shaped slot; Anodal hole is offered in described upper surface, and anodal Kong Zhongshe positive plate, positive plate lower surface are higher than aperture face under the anodal hole; The negative pole hole is offered in described lower surface, and the negative pole device passes the negative pole hole, and the negative pole device comprises spring, and the spring epimere is enclosed within the negative pole cap, and the negative pole cap passes the negative pole hole; Connect attaching plug on the shell.
The positive plate of this charger is located in the anodal hole, thereby positive pole is a kind of concealed positive plate, when the direction of the both positive and negative polarity of battery is put back, the positive pole of battery contacts with the negative pole of charger, and the negative pole of battery can not contact with the positive plate of charger, charge circuit can not conducting, thereby effectively prevents the reverse battery charging.Adopt directly to connect attaching plug on the shell, make the structure of charger compact more, use is carried convenient.
