Description
Technical field
The invention belongs to FPC structure-design technique field, be specifically related to a kind of bending-resistant mobile phone side key panel.
Background technology
It is high that FPC (being called for short FPC) has distribution density; In light weight; Thin thickness, the distribution spatial constraints is less, the flexibility ratio advantages of higher; Meet the compact development trend of electronic product fully, therefore be widely used in PC and fields such as peripheral product, communication product, display and consumption electronic products.
FPC generally comprises and is used for and the extraneous golden finger that is electrically connected usefulness, when installation is used, generally all need bend FPC, so that it is electrically connected with external circuitry.In the existing design; The positive and negative length of finger position place golden finger is consistent, because the golden finger district compares with remaining printed circuit district, has tangible difference of hardness and intensity difference; Also has tangible thickness difference; So in when bending, the golden finger of positive and negative can and the printed wire of softness between the junction produce a bigger shearing force, be easy to take place golden finger from and the printed wire of softness between the phenomenon that fractures of junction.
A kind of FPC that is used for mobile phone is arranged at present, be also referred to as mobile phone side key panel, comprise golden finger end, switch terminals and be used to be connected the connecting plate of golden finger end and switch terminals, said connecting plate is the FPC of yi word pattern; Its golden finger end is linked to the cell phone mainboard back side and is electrically connected usefulness, and switch terminals is folded into the positive button place of cell phone mainboard.In use, said golden finger end is positioned at the below of said switch terminals, and is separated by cell phone mainboard with said switch terminals, and said connecting plate is curled into U-shaped, is used to connect golden finger end and switch terminals; Thereby make this kind mobile phone side key panel form the basic configuration of U-shaped in use.Because connecting plate must be the bending use of curling, and causes connecting plate to rupture easily.In addition, the golden finger of this mobile phone side key panel is because positive finger is concordant with the reverse side finger; During bending; Stress point appears at the diaphragm opening part, also promptly appears at the end that is connected of reverse side finger district and diaphragm, and the diaphragm opening has gummosis after because of lamination; Gummosis forms the otch with difference in height with electroplating the junction, and the two sides incision causes the phenomenon that fractures easily during bending.
Summary of the invention
The purpose of this invention is to provide a kind of mobile phone side key panel that three-dimensional U can be used, have good anti-bending performance that need not to be curled into.
The technical scheme that realizes the object of the invention is: a kind of bending-resistant mobile phone side key panel comprises golden finger end, switch terminals and is used to be connected the connecting plate of golden finger end and switch terminals; The positive and negative of said golden finger end is equipped with golden finger; Said connecting plate and said golden finger end, switch terminals are in the same plane, and said golden finger end is arranged on the front side of switch terminals, and said connecting plate is the FPC of a U-shaped.
In the technique scheme; The top of said connecting plate is arranged on the left-hand end of said switch terminals; The top of said connecting plate extends to form earlier the following bonding pad of connecting plate left; Extend upward the middle bonding pad that forms connecting plate then, extend to form the last bonding pad of connecting plate more to the right, the last bonding pad of said connecting plate is connected with said golden finger end.
In the technique scheme, the top leaving certain gaps uncovered by the economic plan of the bottom of the last bonding pad of said connecting plate and said switch terminals.
In the technique scheme, the bottom of said switch terminals is provided with the stainless steel substrates that is used for fixing installation, and said stainless steel substrates is provided with installing hole.
In the technique scheme, the outboard end of said positive and negative golden finger is concordant, the setting of staggering of the medial extremity of the medial extremity of front golden finger and reverse side golden finger.
In the technique scheme, said front golden finger is longer 0.15 millimeter to 1.5 millimeters than reverse side golden finger.
In the technique scheme, the reverse side of said golden finger end is fitted with diaphragm, and the outboard end of said diaphragm is in abutting connection with the medial extremity of said reverse side golden finger.
In the technique scheme, the length of said front golden finger is 2.1 millimeters, and the length of reverse side golden finger is 1.9 millimeters.
In the technique scheme, the positive and negative of said golden finger end is provided with pad, and said golden finger is arranged in the pad; The outboard end of said positive and negative pad is concordant, the setting of staggering of the medial extremity of the medial extremity of front pad and reverse side pad; The length difference of said front pad medial extremity and reverse side pad medial extremity is 0.15 millimeter to 1.5 millimeters.
In the technique scheme, the reverse side of said golden finger end is fitted with diaphragm, and the outboard end of said diaphragm is in abutting connection with the medial extremity of said reverse side pad; Said front pad is longer 0.15 millimeter to 1.5 millimeters than reverse side pad.
The present invention has positive effect:
(1) among the present invention, said connecting plate and said golden finger end, switch terminals are in the same plane, and said golden finger end is arranged on the front side of switch terminals, and said connecting plate is the FPC of a U-shaped.Compare with traditional mobile phone side key panel, during use, need not to be curled into three-dimensional U-shaped, and just the golden finger end is pressed down a little, can make cell phone mainboard be in the breach of connecting plate, changed its user mode, thereby had good anti-bending effect.
(2) among the present invention, the outboard end of said positive and negative golden finger is concordant, the setting of staggering of the medial extremity of said front golden finger and the medial extremity of reverse side golden finger.Because the finger length of positive and negative is inequality, double-edged shear line is inequality when bending, has strengthened anti-bending performance.
(3) among the present invention, the positive and negative of said golden finger end is provided with pad, and the outboard end of said positive and negative pad is concordant, the setting of staggering of the medial extremity of said front pad and the medial extremity of reverse side pad; The length difference of said front pad medial extremity and reverse side pad medial extremity is 0.15 millimeter to 1.5 millimeters.Because pad also belongs to the harden zone, the pad length through positive and negative is set to inequality, when bending, makes its double-edged shear line inequality, thereby has also strengthened anti-bending performance.
