Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Consult Fig. 1 and Fig. 2, embodiments provide a kind of flexible print circuit board assembly, comprise wiring board 10 and block 20, wherein, wiring board 10 comprises the first connecting portion 11, second connecting portion 12 and kink 13, after wiring board 10 is folding, first connecting portion 11 and the second connecting portion 12 are oppositely arranged, block 20 is located between the first connecting portion 11 and the second connecting portion 12, be connected on kink 13 and away from the juncture area 100 of kink 13 and the first connecting portion 11.
The position that wiring board 10 is easily torn is the connecting portion of the first connecting portion 11 and kink 13, and second connecting portion (i.e. juncture area 100) of connecting portion 12 and kink 13, the force application part contacted with kink 13 due to block 20 is not at juncture area 100, after wiring board 10 bends, the setting of block 20 makes the force part of wiring board 10 shift, the stress that the position of easily tearing receives diminishes, and the tear resistance of wiring board 10 is better, structural strength is higher, longer service life.
First connecting portion 11 is provided with notch part 13a in the Width both sides of the juncture area 100 be connected with kink 13, and by such setting, wiring board 10 bends more smooth, and the kink 13 after bending is more level and smooth.
In the present embodiment, notch part 13a is circular arc, compares the shearing force that the structures such as square, zigzag can bear larger.Further, wiring board 10 is also provided with reinforcing steel 13b along the edge of notch part 13a, and reinforcing steel 13b is preferably sheet metal, can strengthen the shearing resistance dynamics at notch part 13a edge.
This flexible print circuit board assembly also comprises stiffening plate 13c further, and this stiffening plate 13c is mounted on kink 13 outer surface and at least covers juncture area 100, can prevent kink 13 from tearing disconnection from the first connecting portion 11 in the bent state.
Composition graphs 3 and Fig. 4, electronic equipment of the present invention comprises housing 1 and this flexible print circuit board assembly, and the components and parts such as display screen (not shown), housing 1 offers through hole 1a, flexible print circuit board assembly is through through hole 1a, and the components and parts of the first connecting portion 11 and the second connecting portion 12 difference connecting through hole 1a both sides, first connecting portion 11 of the present embodiment is electrically connected with touch-screen, second connecting portion 12 is electrically connected with mainboard 2, and block 20 is fixed in through hole 1a.
