Problems solved by technology

[0002] The power supply batteries of traditional handheld terminals such as mobile phones and PDAs usually only have one charging interface, which is usually set at the bottom of the battery, and the bottom of the battery is provided with positive and negative electrodes and a protective plate. See figure 1 , when charging it, the path of the charging current is: mobile terminal charging interface-handheld terminal small board (mainboard of the handheld terminal charging interface)-FPC (FlexiblePrintedCircuitboard, flexible circuit board)-handheld terminal mainboard-connector-charging It can be seen that when using the above path to charge the rechargeable battery, the charging current travels longer and passes through too many devices. Because each device has impedance, it will consume current, resulting in low charging efficiency, slow charging speed, and high heat generation. question

Abstract

The invention provides a handheld terminal. The handheld terminal comprises a first connector and a second connector which are arranged in a handheld terminal battery jar. The first connector is connected to a charging interface of the handheld terminal through a handheld terminal main board, a flexible circuit board and a handheld terminal small board in sequence. The second connector is connected to the charging interface of the handheld terminal through the handheld terminal small board. When a battery is charged, charging current flowing across a second charging path is larger than charging current in a first charging path as the resistance value of the second charging path is small, and the total electrical loss in the charging process is small as the electrical loss in the second charging path is smaller than the electrical loss in the first charging path; thus, little heat is released, the purpose of improving charging efficiency is improved, and charging time is shortened.

Description

technical field [0001] The invention relates to the technical field of mobile terminal power supply circuits, and in particular to a handheld terminal. Background technique [0002] The power supply batteries of traditional handheld terminals such as mobile phones and PDAs usually only have one charging interface, which is usually set at the bottom of the battery, and the bottom of the battery is provided with positive and negative electrodes and a protective plate. See figure 1 , when charging it, the path of the charging current is: mobile terminal charging interface-handheld terminal small board (mainboard of the handheld terminal charging interface)-FPC (FlexiblePrintedCircuitboard, flexible circuit board)-handheld terminal mainboard-connector-charging It can be seen that when using the above path to charge the rechargeable battery, the charging current travels longer and passes through too many devices. Since each device has impedance, it will consume current, resulting...
