Problems solved by technology

[0004] It can be seen from this that the charging path from the USB port to the battery pack is long. When a large current passes through, the path loss is large, and the connecting terminal of the connector heats up seriously, which makes the charging efficiency low and the entire charging path generates heat.

Embodiment Construction

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0028] It should be noted that, in the mobile terminal of the related art, in order to reduce the path impedance to improve the charging efficiency, the charging path is usually optimized by reducing the impedance value of each device on the charging path, for example, widening the main board wiring of the charging path. However, the above technical solution optimizes the path impedance only from the perspective of the impedance value of the device, and the widening of the charging line is limited by the area of ​​the main board, ...

Abstract

The invention discloses a mobile terminal. The mobile terminal comprises a charging interface and a small board; the charging interface is connected with the small plate, or the charging interface is arranged on the small plate; the mobile terminal further comprises a charging processing circuit, a battery assembly, a first connector and a second connector. The charging processing circuit is arranged on the small board, and the input end of the charging processing circuit is connected with the charging interface; the first end of the first connector is connected with the charging processing circuit, and the second end is connected with the anode of the battery assembly. The cathode of the battery assembly is connected with the second connector. According to the mobile terminal, the charging path can be shortened through the two connectors, and the path impedance is reduced, so that the heating of the charging path is reduced while the charging efficiency is improved, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a mobile terminal. Background technique [0002] With the continuous popularization of mobile terminals, people have higher and higher charging requirements for battery components of mobile terminals. In related technologies, taking mobile terminals as mobile phones as an example, battery components are usually figure 1 Assemble as shown. [0003] Depend on figure 1 It can be seen that when the battery pack is being charged, the charging current passes through the USB port of the mobile phone, passes through the flexible printed circuit (FPC), and then enters the battery pack from the positive terminal of the connector, and then enters the battery pack from the negative terminal in the connector. Connect terminal, FPC back to USB. [0004] It can be seen from this that the charging path from the USB port to the battery pack is long. When a large current passes...
