Description
Technical field
Field of circuit boards is the utility model is related to, more particularly, to flexible PCB.
Background technology
Flexible PCB (Flexible Printed Circuit abbreviation FPC) is using polyimides or polyester film as base
A kind of flexible printed circuit board (PCB) made of material, it has the characteristics that, and Distribution density is high, light-weight, thickness is thin, bending is good.
For the consideration for saving space etc., flexible PCB needs to be bent (as shown in Figure of description 1) after welding, by
The stress concentration at folding line, therefore it is easy to situation about tearing occur.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of flexible circuit for avoiding tearing after bending
Plate, the bending place for solving the problems, such as flexible PCB in the prior art are easily torn.
Technical solution is used by the utility model solves its technical problem：
A kind of flexible PCB for tearing after avoiding bending, including the first plate and stretched out from the side of the first plate the
Two plates, the position being connected in side with the second plate on the first plate are equipped with groove.
As the further improved procedure of such scheme, the position that the bottom of groove is connected with the second plate is equipped with fillet.
As the further improved procedure of such scheme, crack arrest part is circumferentially with along groove on the first plate.
As the further improved procedure of such scheme, crack arrest part includes the first crack arrest part parallel with side, Yi Jiyu
The second vertical crack arrest part of side, wherein, the first crack arrest part is arranged on side of the groove away from side, and the second crack arrest part is arranged on groove
Close to the side of the second plate, and the both ends of the first crack arrest part and the both ends of the second crack arrest part exceed groove.
As the further improved procedure of such scheme, crack arrest part is the copper wire being embedded in the first plate.
The beneficial effects of the utility model are：
The utility model is by setting groove so that flexible PCB is no longer influenced by involving and limiting for main part, folding
Curved region has enough deformation sections, so as to reduce the stress at folding line, effectively avoids flexible PCB from tearing
The phenomenon split.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the side view that flexible PCB is connected with pcb board in the prior art；
Fig. 2 is the front view before the bending of the utility model one embodiment；
Fig. 3 is the side view after the bending of the utility model one embodiment.
Embodiment
Carried out below with reference to the technique effect of the design of embodiment and attached drawing to the utility model, concrete structure and generation
Clear, complete description, to be completely understood by the purpose of this utility model, scheme and effect.It should be noted that do not conflicting
In the case of, the feature in embodiment and embodiment in the application can be mutually combined.
It should be noted that unless otherwise specified, when a certain feature is referred to as " fixing ", " connection " in another feature,
It can directly fix, be connected in another feature, can also indirectly fix, be connected in another feature.In addition, this
The descriptions such as the up, down, left, right, before and after used in utility model are only relative to each composition portion of the utility model in attached drawing
For the mutual alignment relation divided.
In addition, unless otherwise defined, the technology of all of technologies and scientific terms used here by the article and the art
The normally understood implication of personnel is identical.Term used in the description is intended merely to description specific embodiment herein, without
It is to limit the present invention.Term as used herein " and/or " include the arbitrary of one or more relevant Listed Items
Combination.
With reference to Fig. 1, the side view that flexible PCB is connected with pcb board in the prior art is shown.It is as shown in the figure, flexible
A part of structure on circuit board 100 needs opposite main part to bend, since the both sides of bending part can be subject to main part
Involve and limit, therefore stress concentration can be caused at folding line 200 so that flexible PCB 100 holds very much at folding line 200
Easily there is a phenomenon where tearing, product quality is seriously affected.
Based on this, with reference to Fig. 2,3, respectively illustrate the utility model one embodiment bending before front view and bending after
Side view.As shown in the figure, the utility model includes the first plate 110 and the second plate stretched out from the side of the first plate 110
120.It is only a kind of embodiment of the utility model flexible PCB shown in figure, the shape of the first plate 110 and the second plate 120,
Quantity does not limit.
The position being connected on first plate 110 in above-mentioned side with the second plate 120 is equipped with groove 101, which can make
The both sides for obtaining the second plate 120 (i.e. above-mentioned bending part) are no longer influenced by involving and limiting for the first plate 110 (i.e. aforementioned body part)
System, compared to Figure 1, the bending region of the second plate 120 has enough deformation sections, so as to reduce at folding line 200
Stress, effectively avoids flexible PCB from the phenomenon torn occur.
Preferably, the position that the bottom of groove 101 is connected with the second plate 120 is equipped with fillet, can be into by round-corner transition
One step reduces stress.For ease of processing, the bottom of the present embodiment further groove 101 is semicircle.
In addition, the utility model is also provided with crack arrest part on the first plate 110, crack arrest part is circumferentially disposed along groove 101,
Even if flexible PCB is torn, crack arrest part can also control slight crack in setting regions, avoid the second plate 120 and the first plate
110 are fully disconnected.
Specifically, crack arrest part includes the first crack arrest part 130 parallel with above-mentioned side, and vertical with above-mentioned side
Two crack arrest parts 140, i.e. crack arrest part are into " L " type.Wherein, the first crack arrest part 130 is arranged on side of the groove 101 away from side, is used for
Crack arrest along on 101 length direction of groove；Second crack arrest part 140 is arranged on groove 101 close to the side of the second plate 120, for edge
Crack arrest on 101 width of groove, the both ends of the first crack arrest part 130 and the both ends of the second crack arrest part 140 exceed groove.
Preferably, crack arrest part is the copper wire being embedded in the first plate 110.
Above is the preferable of the utility model is implemented to be illustrated, but the invention is not limited to the reality
Example is applied, those skilled in the art can also make a variety of equivalent variations on the premise of without prejudice to the utility model spirit
Or replace, these equivalent deformations or replacement are all contained in the application claim limited range.
