Problems solved by technology

[0006] However, the FPCB designed in the foldable mobile phone as described above has a drawback because the middle part of the FPCB housed in the hinge mechanism may be damaged due to twisting caused by the frequent rotational movement of the cover relative to the main body And bending stress can cause resistance changes and short circuits in FPCB

Embodiment Construction

[0024] Such as image 3 As shown, the foldable mobile phone according to the present invention includes: a main body 10, a cover body 50, which is rotatably connected to the main body 10 through a hinge structure; and a flexible printed circuit board (FPCB) connecting mechanism 70, which is used to electrically connect the main body 10 and Cover 50.

[0025] The main body 10 includes a keypad 20 for operating the mobile phone; a microphone 11 for inputting voice signals; a main printed circuit board (PCB) 30 on which devices for operating the mobile phone in cooperation with the keypad 20 and the microphone 11 are mounted; and the main body FPCB 65 which connects the main PCB to the FPCB connection mechanism 70 . The cover body 50 includes: a loudspeaker 51, which is used to output voice signals; a display screen 53, which is used to display various operating information of the mobile phone; an auxiliary PCB 60, on which the loudspeaker 51 and the display screen 53 are assemb...

Abstract

A flexible printed circuit board (FPCB) connection mechanism of the present invention includes a first connector which is connected to one end of a first FPCB and a second connector which rotatably coupled with the first connector and is connected to one end of a second FPCB. The FPCB connection mechanism of the present invention provides a mechanical and electrical connection between the main body and the cover body of the handset without twisting of two FPCBs that are respectively connected to the main PCB of the main body and the auxiliary PCB of the cover body so to avoid the physical damage of the FPCBs caused by frequent rotational movement of the cover body in relation to the main body and prevent the physical damages of FPCBs from changing the circuitry resistances or shorting the circuitry.

Description

technical field [0001] The present invention relates to mobile handsets, and in particular to flexible printed circuit board (FPCB) connections. Background technique [0002] Generally, a foldable mobile phone is composed of a main body (main body) and a cover body (cover body), wherein the main body includes a printed circuit board (PCB) on which components for cooperatively driving a keypad, a microphone and an earpiece are assembled; and a cover body The body includes another PCB on which the components for operating the speaker and display are mounted; the body and cover are pivotally connected by a hinge structure. The PCBs of the main body and the cover are connected by a flexible printed circuit board (FPCB) to accommodate the movement of the hinge structure. [0003] figure 1 It is a perspective view explaining a normal folding mobile phone. Such as figure 1 As shown, the first PCB 130 of the main body 100 and the second PCB 160 of the cover 150 are connected thr...
