Abstract
The utility model proposes a kind of anti-golden finger fracture flexible wires plate, comprise baseplate of flexible circuit board, multiple golden finger, coverlay, the tow sides of described baseplate of flexible circuit board are provided with described golden finger, described golden finger comprises finger, lead-in wire and head, described lead-in wire is provided with via, described via is communicated with described double-edged golden finger, and the border of described via protrudes from the width of described lead-in wire; The both sides of described finger are provided with protruding triangle; Described coverlay is located at double-edged described baseplate of flexible circuit board surface, the design increases the via that a misarrangement is opened above golden finger, again golden finger two sides finger is all wired to increased via to get on, even if so in use golden finger any surface rupture of finger, capital is pointed and conducting by another side again, thus can improve the useful life of welding finger, and on finger, be provided with the projection staggered, what can balance golden finger is subject to stress, prevents golden finger from rupturing.
Description
Technical field
The utility model relates to flexible circuit board field, especially relates to a kind of anti-golden finger fracture flexible wires plate.
Background technology
Along with TFTLCD module is more and more thinner, price is more and more lower, a lot of employing connector connects TFTLCD liquid crystal module and generally selects golden finger welding to replace expensive ZIF and BTB, but adopt during golden finger welding and affect doing over again and useful life of product because golden finger easily fractures in terminal applies, the design is this field of improvement and provides one reliably cutting edge technology in the golden finger performance that fractures, thus can substantially increase the useful life of product and reduce maintenance rate of doing over again.
Utility model content
For solving flexible PCB when the External Force Acting such as lighting by welding, bending, frock clamp, stress point concentrates on finger or the end of golden finger, and golden finger easily to fracture the technical problem come off from flexible print circuit board.
The utility model proposes a kind of anti-golden finger fracture flexible wires plate, comprise baseplate of flexible circuit board, multiple golden finger, coverlay, the tow sides of described baseplate of flexible circuit board are provided with described golden finger, described golden finger comprises finger, lead-in wire and head, described lead-in wire is provided with via, described via is communicated with described double-edged golden finger, and the border of described via protrudes from the width of described lead-in wire; The both sides of described finger are provided with protruding triangle; Described coverlay is located at double-edged described baseplate of flexible circuit board surface.
The further preferred version that the utility model proposes, described via is mutually staggered on the lead-in wire of multiple described golden finger.
The further preferred version that the utility model proposes, the triangle of the both sides projection of described finger is mutually staggered on multiple golden finger.
The further preferred version that the utility model proposes, described head is that semicircle is positioned at one end, finger.
The further preferred version that the utility model proposes, described coverlay is polyimide film.
The further preferred version that the utility model proposes, described finger can be opened for size error.
The anti-golden finger fracture flexible wires plate that the utility model proposes has following beneficial effect: the design increases the via that a misarrangement is opened above golden finger, again golden finger two sides finger is all wired to increased via to get on, even if so in use golden finger any surface rupture of finger, capital is pointed and conducting by another side again, thus the useful life of welding finger can be improved, and on finger, be provided with the projection staggered, what can balance golden finger is subject to stress, prevents golden finger from rupturing.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is structural representation of the present utility model;
Wherein, 1-baseplate of flexible circuit board, 2-golden finger, 3-coverlay, 4-finger, 5-goes between, 6-head, 7-via, the triangle of 8-projection.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Composition graphs 1, the utility model proposes a kind of anti-golden finger fracture flexible wires plate, comprise baseplate of flexible circuit board 1, multiple golden finger 2, coverlay 3, the tow sides of described baseplate of flexible circuit board 1 are provided with described golden finger 2, described golden finger 2 comprises finger 4, lead-in wire 5 and head 6, described lead-in wire 5 is provided with via 7, described via 7 is communicated with described double-edged golden finger 2, the border of described via 7 protrudes from the width of described lead-in wire 5, the design increases the via 7 that a misarrangement is opened above golden finger 2, again finger, golden finger 2 two sides 4 is all wired to increased via 7 to get on, even if so in use rupture in golden finger 2 any surface finger 4, capital is the conducting by another side finger 4 again, thus the useful life of welding finger 4 can be improved, the both sides of described finger 4 are provided with protruding triangle 8, can the even stress that is subject to when plug of finger 4, described coverlay 3 is located at double-edged described baseplate of flexible circuit board 1 surface.
The further preferred version that the utility model proposes, described via 7 is mutually staggered on the lead-in wire 5 of multiple described golden finger 2, and through hole staggers mutually, can prevent hypotelorism between adjacent through hole, when under tension, close power can make product be more vulnerable to infringement.
The further preferred version that the utility model proposes, the triangle 8 of the both sides projection of described finger 4 is mutually staggered on multiple golden finger 2, not on the same line, dispersion of exerting all one's strength, reduces the possibility that finger 4 is damaged to the stress that finger 4 can be subject to by the triangle that arrangement is staggered.
The further preferred version that the utility model proposes, described head 6 is positioned at one end, finger 4 for semicircle.
The further preferred version that the utility model proposes, described coverlay 3 is polyimide film.
The further preferred version that the utility model proposes, described finger 4 can be opened for size error, the finger 4 of different length, also can exert all one's strength the power that is subject to not on the same line, reduces and damages risk.
This design ap-plication is among the flexible FPC design of LCM module, and after dropping into application, the fraction defective of golden finger 2 is reduced to 0% substantially.
To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
