Embodiment Construction

[0019] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0020] Such as image 3 As shown, the rechargeable battery 2 of this embodiment includes a rectangular parallelepiped battery cell 21, three golden fingers 222 and a protective circuit board 221, and the golden fingers 222 and the protective circuit board 221 are respectively arranged on adjacent sides of the rectangular parallelepiped. The two surfaces are electrically connected through a rigid-flex board, and a rigid-flex board is a technical term in the field. During actual production, it is also possible to adopt a structural form in which the golden fingers 222 and the protective circuit board 221 are respectively arranged on two opposite surfaces of the cuboid, and a flexible printed circuit board (Flexible Printed Circuit Board) can also be used between the two. , FPC) electrical connections.

[0021] By arranging the...

Abstract

The invention discloses a rechargeable battery and a mobile terminal including the same. The rechargeable battery comprises a battery cell, three connecting fingers and a protective circuit board. The battery cell is a cuboid, the connecting fingers are arranged on the first surface of the cuboid, and the protective circuit board is arranged on the second surface of the cuboid. The connecting fingers and the protective circuit board are arranged on the different surfaces of the battery cell, so that the connecting fingers and the circuit board of the mobile terminal are in close electrical contact, and the protective circuit board is kept away from the circuit board of the mobile terminal, thus preventing the signal interference derived from the circuit board of the mobile terminal, and problems of automatic shutdown and power-down of the mobile terminal are solved, and the output voltage stability is improved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a rechargeable battery and a mobile terminal containing it. Background technique [0002] As an energy storage device, rechargeable batteries play an important role in mobile terminals. Some of its performance parameters, such as capacity, power supply stability, and charge and discharge times, are directly related to the stability and service life of mobile phone signals. [0003] Such as figure 1 As shown, the existing rechargeable battery, such as the existing mobile phone battery 1, includes an electric core 11 and a circuit board 12, and the two ends of the circuit board 12 are connected to the positive and negative poles of the electric core 11 through nickel strips. Such as figure 2 As shown, the circuit board 12 includes three golden fingers 121 and a protection circuit board 122 . During installation, these golden fingers 121 are electrically connected with the ...
