At present, as shown in Fig. 1 to Fig. 3 of description, the bending place of flexible circuit board 10' of prior art and/or junction are commonly kink 20', i.e. the transitional region that folding line is formed, when producing assembling, the kink 20' of flexible circuit board 10' easily makes it pull apart and tearing, and such defect problem not only causes the waste of flexible circuit board 10', increase the cost budgeting of enterprise, also can affect the shipment progress of finished product.
Therefore, it is necessary to provide a kind of technological means to solve drawbacks described above.
Summary of the invention
It is an object of the invention to provide the contour structures of a kind of flexible circuit board and there is the flexible PCB of this contour structures, easily pulling apart and the problem of tearing solving the flexible circuit board of prior art.
For reaching this purpose, the present invention by the following technical solutions:
The anti-fracture structure of a kind of flexible circuit board, including the tortuous portion being arranged at flexible circuit board bending place and/or junction.
As further preferred version, described tortuous portion uses arcuate structure.
As further preferred version, described tortuous portion uses U-shaped structure.
As further preferred version, described tortuous portion uses S-shaped structure.
As further preferred version, described tortuous portion includes using between multiple curved portions, and multiple curved portions seamlessly transitting.
The application in flexible circuit board of a kind of above-mentioned anti-fracture structure.
A kind of flexible circuit board, including body, described body is provided with tortuous portion in its bending place and/or junction.
As further preferred version, described tortuous portion uses arcuate structure, U-shaped structure or S-shaped structure.
As further preferred version, described tortuous portion includes using between multiple curved portions, and multiple curved portions seamlessly transitting.
The invention have the benefit that due to, bending place and/or the junction of current flexible circuit board are commonly kink, that is, the transitional region that folding line is formed, and kink easily produces stress and concentrates, thus, when producing assembling, the kink of flexible circuit board easily makes it pull apart and tearing, and is arranged at the tortuous portion of flexible circuit board bending place and/or junction in this case, stress is concentrated less, and when being effectively prevented from producing assembling, flexible circuit board is easily pulled apart and the problem of tearing.

Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
Refer to shown in Fig. 1 to Fig. 3, the bending place of the flexible circuit board 10 ' of prior art and/or junction are commonly kink 20', i.e., the transitional region that folding line is formed, and kink 20' easily produces stress and concentrates, thus, when producing assembling, the kink 20' of flexible circuit board 10' easily makes it pull apart and tearing.
Referring to shown in Fig. 4 to Fig. 8, the present invention provides the anti-fracture structure of a kind of flexible circuit board, including the tortuous portion 20 being arranged at flexible circuit board 10 bending place and/or junction.Due to be arranged at flexible circuit board 10 bending place and/or junction for tortuous portion 20, and tortuous portion 20 is relative to kink 20', and its stress is concentrated less, and when can be effectively prevented from producing assembling, flexible circuit board 10 is easily pulled apart and the problem of tearing.
Embodiment one
Referring to shown in Fig. 4 to Fig. 6, tortuous portion 20 uses arcuate structure 21.Wherein, arcuate structure 21 is not only easy to processing, and its stress that can preferably reduce bending place and/or junction is concentrated, and the most preferably prevents pulling apart and tearing of flexible circuit board 10.
Embodiment two
Referring to shown in Fig. 7, tortuous portion 20 uses U-shaped structure 22.Specifically, U-shaped structure 22 is concentrated except the stress preferably reducing bending place and/or junction, prevents pulling apart and tearing of flexible circuit board 10, moreover it is possible to ensure the attractive in appearance of flexible circuit board 10.
Embodiment three
Referring to shown in Fig. 8, tortuous portion 20 uses S-shaped structure 23.S-shaped structure 23 is compared to arcuate structure 21, U-shaped structure 22, and its stress that more can reduce bending place and/or junction is concentrated, but its processing is the most relatively cumbersome.
Specifically, tortuous portion 20 includes using between multiple curved portions, and multiple curved portions seamlessly transitting.Wherein, this curved portions is arcuate structure 21, U-shaped structure 22 or S-shaped structure 23, and the tortuous portion 20 that multiple curved portions is formed is in wavelike structure, and this kind of structure is suitable for application in requiring to prevent pulling apart the higher flexible PCB of coefficient 10.
The present invention also provides for the application in flexible circuit board 10 of a kind of above-mentioned anti-fracture structure.
The present invention also provides for a kind of flexible circuit board 10, and including body 11, body 11 is provided with tortuous portion 20 in its bending place and/or junction.
