Detailed Description

The utility model is further described below with reference to the accompanying drawings:

referring to fig. 1 to 4, a portable battery charger comprises a box body 1, a circuit board 2 for charging and discharging is adaptively attached to the inner bottom surface of the box body 1, a plurality of groups of positive and negative electrodes 21 which are parallelly arranged are fixedly welded on the top surface of the circuit board 2, and a charging and discharging port 22 which extends out of the box body 1, and a foam limiting cavity 3 which is adaptive to the peripheral wall of the box body 1 and used for clamping a discharging battery 100 is further arranged in the box body 1. The charge and discharge ports 22 may be provided at the edge of the circuit board 2 and extend laterally from the side walls of the case body 1,

when the rechargeable battery 100 is used, the rechargeable battery 100 is placed in the box body 1, the charger can be used for storing and carrying the battery 100, can charge the battery 100, can be used as a standby power supply to supply power for other electronic products, and simplifies the charging products required to be carried during outgoing; the limit cavity 3 of foam is arranged in the box body 1, so that protection and buffering can be formed for the battery 100, and the reliability and safety are high; in addition, the circuit board 2 is embedded below the limiting cavity 3, so that the charger is compact in structure and small in size.

In this embodiment, the positive electrode of the positive electrode 21 is a U-shaped metal rod 21a with two ends vertically inserted on the circuit board 2, and the negative electrode is a spring 21b coaxially disposed with the battery 100. The positive and negative electrodes 21 are welded and fixed on the circuit board 2, so that the reliability of the positive and negative electrodes 21 is guaranteed, and the limiting cavity 3 made of foam is convenient to set.
