The exemplary embodiment(s) of the present invention relates to a field of a flexible print circuit board bending method for connecting in a cell phone and a flexible print circuit board thereof. More specifically, the exemplary embodiment(s) of the present invention relates to an assembling way and that could decrease the space occupied by the devices in the cell phone.
With the advances in the technology, the invented cell phone makes lots of conveniences to the modern people. The cell phone not only has the functions of communicating with other people or sending messages at any time, but also has lots of advantages such as easy to carry, and thus the cell phones become an indispensable and important communication tool. With the progress of the nowadays technology, the functions of the cell phones are updated and advanced daily and daily, and cell phones having a processor that increases the computing ability are becoming a trend. However, the functions such as tacking pictures or recording of this kind of cell phone are much more than the conventional cell phone, and thus the electronic devices of this kind of cell phone are more complicated than the conventional cell phone.
In the nowadays technology, a flexible print circuit board (FPC) is used as a bridging unit to electrically connect the components with each other when assembling the cell phone, and both sides of the FPC are provided with holes as the means of plugging connection, and the electronic components (for example a switch unit, a sound receiver, a circuit main board or an audio device) of the cell phone are disposed on both front and back side of the FPC. This kind of method that arranges holes on both sides of the FPC needs more steps when processing, and causes the cost higher and higher. In addition, the arranging of the conventional FPC occupies more space in the cell phone, and thus it is not the best way to arrange the accommodation space in the cell phone to the man who wants to increase the inside space of the cell phone. According to the afore-described problems, the inventors of the present invention designed a flexible print circuit board bending method for connecting in a cell phone and a flexible print circuit board thereof, so as to solve the problems of the prior arts.
To solve the problems in the conventional arts, it is a primary object of the present invention to provide a flexible print circuit board bending method for connecting in a cell phone and a flexible print circuit board thereof.
To achieve the above object, a flexible print circuit board bending method for connecting in a cell phone according to the present invention comprises the following steps of: A. arranging a plurality of connecting points on one side of the flexible printed circuit board; B. bending the flexible printed circuit board to form the flexible printed circuit board as a L shape to decrease the space occupied by the flexible printed circuit board, and each connecting point is exposed to the outside for electrically connecting; and C. assembling the flexible printed circuit board into a smart phone, and connecting the connecting points correspondingly to a plurality of devices such as a switch unit, a sound receiver, a circuit main board or an audio device inside the smart phone, so as to electronically connect to each others.
Preferably, the flexible printed circuit board comprises a base section having a first connecting point, and the base section extends a first extending arm toward one side of the base section, the first extending arm is perpendicularly bended at one extending end and further extends to form a perpendicular extending arm, and a second connecting point is disposed on one extending end of the perpendicular extending arm, and the base section extends a second extending arm toward another side of the base section, a third connecting point is disposed on the second extending arm, and a connecting piece is extended from a lateral side of the third connecting point, a fourth connecting point is further disposed on the connecting piece.
Preferably, in the step B, a root section of the first extending arm is bended toward the a perpendicular side corresponding to the base section, and then the perpendicular extending arm is folded several times so as to face the second connecting point to the back side, and then the second extending arm is rolled correspondingly to the base section from the root section of the second extending arm so as to face the front side of the second extending arm to the back side, and lastly the connecting piece is stood by perpendicularly bending the connecting piece.
Preferably, in the step C, the stood connecting piece is corresponded to a top end of the smart phone, and the fourth connecting point is connected and fixed to the switch unit, and the third connecting point is correspondingly connected to the sound receiver, and the second connecting point is correspondingly connected to the circuit main board, and the first connecting point is correspondingly connected to audio device.
To achieve another object, a flexible print circuit board according to the present invention is disclosed, which comprises a base section having a first connecting point, and the base section extends a first extending arm toward one side of the base section, the first extending arm is perpendicularly bended at one extending end and further extends to form a perpendicular extending arm, and a second connecting point is disposed on one extending end of the perpendicular extending arm, and the base section extends a second extending arm toward another side of the base section, a third connecting point is disposed on the second extending arm, and a connecting piece is extended from a lateral side of the third connecting point, a fourth connecting point is further disposed on the connecting piece.
With the above arrangements, the flexible print circuit board bending method according to the present invention is designed to bend the FPC at several positions, and thus connect the components disposed on the front and back sides of the FPC. Therefore, the FPC could be provided with connecting points only on one side, and thus does decrease the manufacturing cost. In addition, after folding the FPC, the space occupied in the cell phone could be exactly decreased and could further thin and lighten the cell phone.
