Abstract
A combining connector for a flexible printed circuit comprises flexible circuit boards, scraps and connecting structures connected among the flexible circuit board and the scrapes. Each connecting structure comprises a middle insulating layer and a guide copper layer, wherein the middle insulating layer extends from one flexible circuit board to the middle of the scrap, the guide copper layer is coated on the middle insulating layer, a tearing portion with the width smaller than those of two sides is arranged in the middle of the connecting structure, the guide copper layer extends to the tearing portion from the scrap, and the tearing portion is provided with tearing lines along the guide copper layer. The connecting structure is thinned and narrowed locally so that most stress is concentrated on the tearing portion when the connecting structure is torn out; simultaneously, the hardness of the guide copper layer is larger than that of the middle insulating layer, the tearing portion can be cut off along the guide copper layer more directionally, and accordingly damages of the flexible circuit boards due to tearing are avoided.
Description
Technical field
The utility model belongs to flexible circuit board manufacturing technology field, the syndeton between particularly a kind of flexible circuit board.
Background technology
Flexible circuit board all is by a collection of flexible circuit board being produced on together on the monoblock flexible circuit board sheet material usually, with single flexible circuit board stamping-out one by one, then the waste material in zone outside the flexible PCB is removed again, and each flexible circuit board is separated from each other.And under some special situations, such as carrying out the surface adhered with electronic part to the flexible circuit board of justifying, often when the stamping-out circuit board, can between flexible circuit board and waste material, reserve one section small syndeton, as shown in Figure 1, each flexible circuit board links to each other with waste material by syndeton respectively, thereby constitutes the combined connection component of a flexible circuit board.The combined connection component of the flexible circuit board of monoblock just can integral body be sent into surface-mounting equipment and is processed like this, and no longer needs to utilize other moulds that each flexible circuit board is carried out surface mount after fixing separately again, and then enhances productivity.
After the surface adhered with electronic part, need above-mentioned syndeton be cut off by the mode that cross cutting or hand tear, thereby flexible circuit board is separated with waste material, so that flexible circuit board and other hardware configurations are assembled.
The syndeton of using always in the prior art as shown in Figure 2, the copper layer is not laid at this syndeton place, but have the last insulating barrier, intermediate insulating layer, the following insulating barrier that link to each other with flexible circuit board and waste material, and syndeton is rectangular, because everywhere material thickness is identical on the syndeton, therefore the inside of syndeton is not easy to the position of rupturing, the stress major part all concentrates on the P point adjacent with flexible circuit board, this just cause hand tear or cross cutting in tear flexible circuit board easily to shreds, make copper conductor by tear fracture, cause waste material.
Summary of the invention
The purpose of this utility model is to overcome in the prior art problem of damaging flexible circuit board when cutting apart flexible circuit board easily, provides a kind of easily at the combined connection component of the flexible circuit board of syndeton place tear fracture.
For achieving the above object, the technical solution adopted in the utility model is: a kind of combined connection component of flexible circuit board, comprise flexible circuit board, waste material and be connected flexible circuit board and waste material between syndeton, described syndeton comprises the intermediate insulating layer that extends to described waste material from described flexible circuit board, guiding copper layer on the described intermediate insulating layer is laid in, the middle part of described syndeton has the tear portion of width less than both sides, described guiding copper layer extends to the described portion of tearing from described waste material, and the described portion of tearing forms tear line along described guiding copper layer.
Preferably, described waste material also has and covers described the last insulating barrier of going up guiding copper layer top, covers the described following insulating barrier that guides down on the copper layer.
Preferably, described guiding copper layer comprise lay respectively at described in the going up guiding copper layer and be arranged in following guiding copper layer below the described layer insulating of layer insulating top.
Preferably, the both sides of described syndeton all offer V-notch, and the described portion of tearing is positioned between two described V-notchs.
The utility model operation principle is: make the attenuation of syndeton place local thickness, narrowed width, make when tearing syndeton, most stress can both focus on the portion of tearing, the guiding copper layer of hardness greater than intermediate insulating layer is set simultaneously, the portion of tearing can be disconnected along the edge of guiding copper layer, and then make the disconnection of syndeton that guidance quality more be arranged.
Because technique scheme utilization, the utility model compared with prior art has following advantage: the utility model is by removing the guiding copper layer at syndeton place selectively, make between two flexible circuit boards and only link to each other by intermediate insulating layer, the thickness attenuation at syndeton place is easier tear fracture therefore, in addition, guiding copper layer is set can also make intermediate insulating layer to avoid tearing to shreds flexible circuit board along the edge that guides the copper layer by neat tearing; By width is set on syndeton, makes the two ends stress of the portion of tearing concentrate, thereby be more conducive to the disconnection of syndeton with respect to the portion of tearing that Road narrows on both sides.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
A kind of combined connection component of flexible circuit board, comprise a plurality of flexible circuit boards 1, be connected waste material 11 between a plurality of flexible circuit boards, be connected the syndeton 2 between flexible circuit board 1 and the waste material 11, each described flexible circuit board 1 all has last insulating barrier 3, intermediate insulating layer 4, following insulating barrier 5, also is provided with single or multiple lift conducting wire layer on each flexible circuit board 1 alternatively.
Described syndeton 2 comprise from described flexible circuit board 1 extend to the intermediate insulating layer 4 of described waste material 11, be laid in described intermediate insulating layer 4 above and belows respectively go up guiding copper layer 6 and guiding copper layer 7 down.The both sides of described syndeton all offer V-notch, make the middle part of described syndeton 2 form width significantly less than the portion of tearing 8 of both sides, and this tears portion 8 between two V-notchs, as shown in Figure 6.The described guiding copper layer 6 of going up extends to the described portion 8 of tearing with following guiding copper layer 7 from described waste material 11, and forms neat edge at the portion of tearing 8 places, makes the portion of tearing 8 form tear line along the described guiding copper layer 6 of going up with following guiding copper layer 7.
