Fig. 2 is refer to, Fig. 2 is a kind of structural representation of embodiment of wiring board provided in an embodiment of the present invention
Figure.
In a kind of embodiment, including the first PCB hardboards 10, the 2nd PCB hardboards 20 and both ends be arranged on it is described
First PCB hardboards 10, the first soft board 30 of the 2nd PCB hardboards 20, the second soft board 40, first soft board 30, described
Two soft boards 40 at the extraction of the first PCB hardboards 10 to the part the 2nd PCB hardboards 20 be the first kink 31,
Second kink 41, central angle corresponding to the circular arc of first kink 31 are preset angle α, and first kink 31 is located at
The inner side of second kink 41.
Second soft board 40 is set by the opposite side in the first PCB hardboards 10 and the 2nd PCB hardboards 20 so that bending
When, when bending angle exceedes preset angle α, the second soft board 40 is binding to the first soft board 30 being easily peeled off originally, Ke Yiyou
Effect prevents the first soft board 30 from being peeled off from the first PCB hardboards 10 or the 2nd PCB hardboards 20, improves the reliability of plate.
In a kind of specific embodiment, preset angle α is 108 °.
It is pointed out that preset angle α is the bending angle of designed in advance in the present invention, the present invention does not do specific to it
Limit.
In a kind of embodiment, the both ends of the first soft board 30 are arranged on the first PCB hardboards 10, the 2nd PCB hardboards
20 upside, if the first PCB hardboards 10 are placed on left, the 2nd PCB hardboards 20 are placed on right, the left end of the first soft board 30
The top of the first PCB hardboards 10 is arranged on, right-hand member is arranged on the top of the second pcb board, and the second soft board 40 is arranged on the first soft board
30 lower section.Then the 2nd PCB hardboards 20 are rotated counterclockwise around the first PCB hardboards 10, until the first PCB hardboards 10 with
First hardboard is parallel, and at this moment part of first soft board 30 between the first PCB hardboards 10, the 2nd PCB hardboards 20 is the first bending
Portion 31, part of second soft board 40 between the first PCB hardboards 10, the 2nd PCB hardboards 20 are the second kink 41, at this moment first
The angle that kink 31 turns over be 180 °, corresponding central angle be 180 °, due to the first kink 31 by the first PCB hardboards 10,
2nd PCB hardboards 20, the semi-surrounding of the second soft board 40, therefore comparatively, the first kink 31 is located at the interior of the second kink 41
Side.The first soft board 30, the second soft board 40 bending during, because the second soft board 40 can be also bent, what is be subject to is total curved
Roll over resistance increase so that the first soft board 30 is not easy to be bent transition, hard from the first PCB this makes it possible to place the first soft board 30
Peeled off on plate 10, the 2nd PCB hardboards 20.
In a kind of specific embodiment, the left surface of the left end of first soft board 30 and the first PCB hardboards 10 is put down
Together, and/or the right-hand member of first soft board 30 is concordant with the right flank of the 2nd PCB hardboards 20.
Likewise, the left end of second soft board 40 and the left surface of the first PCB hardboards 10 are concordant and/or described
The right-hand member of second soft board 40 is concordant with the right flank of the 2nd PCB hardboards 20.
Second soft board 40 is arranged on the lower section of the first soft board 30, and second soft board 40 is arranged on the first PCB hardboards
10th, the part of the 2nd PCB hardboards 20 is arranged on the first PCB hardboards 10, the outside or inside of the 2nd PCB hardboards 20, i.e., and
Two soft boards 40 be arranged on the first PCB hardboards 10, the part of the 2nd PCB hardboards 20 is arranged on the first PCB hardboards 10,
The part of 2nd PCB hardboards 20 is arranged on the first PCB hardboards 10, the downside of the 2nd PCB hardboards 20 (with the first soft board 30 first
Position on PCB hardboards 10, the 2nd PCB hardboards 20 is relative), or it is arranged on the first PCB hardboards 10, the 2nd PCB hardboards 20
Inside, clamped by the first PCB hardboards 10, the 2nd PCB hardboards 20.
Transition is bent using setting the modes of the second soft board 40 to prevent, it is effective to limit the first soft board 30 from first
Peeled off on PCB hardboards 10, the 2nd PCB hardboards 20, typically when making PCB construction, from the first soft board 30, the second soft board 40 and
The outside excessive glue in one PCB hardboards 10, the rigid-flexible place of the 2nd PCB hardboards 20 forms excessive glue area, i.e., described first kink 31, described the
Two kinks 41 are provided with excessive glue area with the first PCB hardboards 10, the junction of the 2nd PCB hardboards 20, can so improve
First soft board 30, the second soft board 40 and the first PCB hardboards 10, the adhesion of the 2nd PCB hardboards 20, improve prevent from being stripped can
Energy property, artificial workflow for dispensing glue is equally decreased, improves operating efficiency.Certainly, if found by detecting, with reference to
Power is inadequate, it is desired nonetheless to carries out certain artificial for dispensing glue.
It is pointed out that in the present invention, it is possible that there is excessive glue phenomenon, professional standard is also to allow to occur<
1.5mm excessive glue, can carry out excessive glue or non-excessive glue as requested, and the present invention is not especially limited to this.
When carrying out PCB construction design, the length of first soft board 30 can be with the length phase of second soft board 40
Deng so using same soft board, after circuit design is completed, directly being suppressed, next year makes PCB construction into, soft board
Shape design is simple, reduces the design of technological parameter, reduces technology difficulty, the first soft board 30, the second soft board 40 are first
Between PCB hardboards 10, the 2nd PCB hardboards 20, the first kink 31, the spacing of the second kink 41 first reduce, until being bonded, so
Original spacing is gradually replied in the other end afterwards；Certain second soft board 40 can be longer than the length of the first soft board 30, as long as
When the first soft board 30 will be folded into preset angle α (such as 180 °), second is soft for first PCB hardboards 10 and the 2nd PCB hardboards 20
Plate 40 can improve extra restraining force, the possibility of the transition of the first soft board 30 bending can so be reduced, as second
The length difference of soft board 40 and the first soft board 30 is how many, is decided by the radius of curvature and spacing therebetween of bending.
In summary, wiring board provided in an embodiment of the present invention, by the another of the first PCB hardboards and the 2nd PCB hardboards
Side sets the second soft board so that in bending, when bending angle exceedes preset angle α, the second soft board to being easily peeled off originally
The first soft board it is binding, can effectively prevent the first soft board from being peeled off from the first PCB hardboards or the 2nd PCB hardboards, improve
The reliability of plate.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The most wide scope caused.
