Description

A kind of anti-fracture structure of backlight FPC pads
Technical field
The utility model is related to back light source technique field, more specifically to a kind of anti-fracture knot of backlight FPC pads Structure.
Background technology
FPC is called flexible circuit board, its have stronger pliability, when using more flexibly and space-consuming is few, each Plant and be widely used on electronic product;Backlight product is in use, light source is generally connected with other client's modules by FPC, the back of the body In light source production process, pad causes line broken circuit compared with easy fracture on FPC circuits, and then causes product rejection.
Utility model content
The technical problems to be solved in the utility model is that the drawbacks described above for prior art is effectively prevented there is provided a kind of The anti-fracture structure of backlight FPC pads that only pad is broken.
The utility model solves the technical scheme that its technical problem used:
Construct a kind of anti-fracture structure of backlight FPC pads, including flexible circuit board;Wherein, set on the flexible circuit board Having be provided with multiple conductive holes on a plurality of pad, the pad;The flexible circuit board is not provided with being provided with the pad one side The reinforcement platelet being fixedly connected with the conductive hole;Stiffener is suppressed with the pad;The stiffener is a plurality of and in institute State and prolong on pad the segmentation distribution setting of its length direction;The reinforcement being set on the outside of the conductive hole is provided with the pad Ring, the reinforcing ring is fixedly connected with the stiffener.
The anti-fracture structure of backlight FPC pads described in the utility model, wherein, the reinforcing ring is insulation cushion rubber.
The anti-fracture structure of backlight FPC pads described in the utility model, wherein, be provided with the reinforcing ring with it is described The groove that stiffener coordinates;The stiffener end is fixed in the groove by glue.
The anti-fracture structure of backlight FPC pads described in the utility model, wherein, the reinforcement platelet is insulating circuit board Or insulating rubber slab.
The anti-fracture structure of backlight FPC pads described in the utility model, wherein, the stiffener is flexible metal strip.
The anti-fracture structure of backlight FPC pads described in the utility model, wherein, it is provided with the single pad many In 3 conductive holes.
The beneficial effects of the utility model are:By suppressing the intensity that stiffener strengthens pad on pad;Pass through weldering Multiple conductive holes are set on disk, increase pad and flexible circuit board contact position, and then play and prevent that pad fracture from causing circuit to break Road situation;Reinforcement platelet is fixedly connected by conductive hole, prevents that conductive hole from coming off, stability and reliability is further improved;It is whole Body is simple in construction, low cost.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below in conjunction with accompanying drawing and reality Applying example, the utility model is described in further detail, and drawings in the following description are only the section Example of the present invention, for this For the those of ordinary skill of field, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings attached Figure:
Fig. 1 is the anti-fracture structural profile zoomed-in view of backlight FPC pads of the utility model preferred embodiment;
Fig. 2 is the anti-fracture structure top view of backlight FPC pads of the utility model preferred embodiment.
Embodiment
In order that the purpose, technical scheme and advantage of the utility model embodiment are clearer, below in conjunction with this practicality Technical scheme in new embodiment carries out clear, complete description, it is clear that described embodiment is portion of the present utility model Divide embodiment, rather than whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art are not paying creation Property work on the premise of the every other embodiment that is obtained, belong to protection domain of the present utility model.
The anti-fracture structure of backlight FPC pads of the utility model preferred embodiment is as shown in figure 1, simultaneously refering to Fig. 2, bag Include to be provided with flexible circuit board 1, flexible circuit board 1 on a plurality of pad 2, pad 2 and be provided with multiple conductive holes 20;Flexible circuit board 1 is not Set and be provided with the reinforcement platelet 10 being fixedly connected with conductive hole 20 in the one side of pad 2;Stiffener 21 is suppressed with pad 2;It is logical Cross and the intensity that stiffener 21 strengthens pad 2 is suppressed on pad 2;By setting multiple conductive holes 20 on pad 2, increase pad 2 With the contact position of flexible circuit board 1, and then play prevent pad 2 fracture cause line broken circuit situation;Fixed and connected by conductive hole 20 Reinforcement platelet 10 is connect, prevents that conductive hole 20 from coming off, stability and reliability is further improved;Overall structure is simple, low cost.
As depicted in figs. 1 and 2, stiffener 21 is a plurality of and prolongs the segmentation distribution setting of its length direction on pad 2, is segmented Distribution is influenceed with being reduced in the guarantee increase intensity of pad 2 simultaneously on the pliability of flexible circuit board 1.
As depicted in figs. 1 and 2, the reinforcing ring 22 for being set in the outside of conductive hole 20 is provided with pad 2, reinforcing ring 22 is with adding Strong bar 21 is fixedly connected, and prevents that pad 2 is broken at it with the junction of conductive hole 20.
As depicted in figs. 1 and 2, reinforcing ring 22 is insulation cushion rubber, ensures the pliability of flexible circuit board 1.
As depicted in figs. 1 and 2, the groove 220 coordinated with stiffener 21 is provided with reinforcing ring 22;The end of stiffener 21 leads to Glue is crossed to be fixed in groove 220;Further prevent that pad 2 is broken at it with the junction of conductive hole 20.
As shown in figure 1, it is insulating circuit board or insulating rubber slab to strengthen platelet 10, prevent that climbing electric situation occurs.
As depicted in figs. 1 and 2, stiffener 21 is flexible metal strip, is reduced while influence on the flexibility of flexible circuit board 1 significantly Strengthen the anti-breaking resistance to spalling of pad 2.
