Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
First please as depicted in figs. 1 and 2, be according to the structural representation of backlight golden finger of the present invention and the structural representation according to main FPC of the present invention respectively.Wherein, described backlight golden finger 1 is for welding with the pad 21 on main FPC2.
In one embodiment, described backlight golden finger 1 has the body 11 of strip, one end of described body 11 has the electroplate lead wire 12 corresponding with pad 21, is provided with the fastener 13 of outside horizontal expansion at least side of body 11 apart from described electroplate lead wire 12 a distance.In a preferred embodiment, be equipped with the fastener 13 of outside horizontal expansion in the both sides of described body 11, make locking effect better.
In another embodiment, described fastener 13 can be one-body molded with the body 11 of described backlight golden finger 1, and fastener 13 can be firmly connected on described body 11.Certainly, described fastener 13 also can be connected in the mode of assembling with body 11, therefore can improve on the backlight golden finger 1 of existing strip, applied widely, more economical environmental protection.Wherein, the mode that group connects comprises conventional mechanical connection manner such as bonding grade.
In another embodiment, the shape of described fastener 13 can be rectangle, can also be triangle, trapezoidal etc., but need to ensure described fastener 13 can engage by the structure corresponding with described fastener 13 set on main FPC2.
In addition, in order to clearly describe the size of the dependency structure of backlight golden finger 1 and main FPC2, in another embodiment, the width defining described body 11 is X
1, body 11 is X together with the width of two fasteners 13
2, the length (bearing of trend along body 11) of described fastener 13 is Y
1, fastener 13 is Y with the distance of electroplate lead wire 12
2.
Especially as shown in Figure 2, in another embodiment, described main FPC2 is provided with pad 21, and the top of pad 21 is provided with the opening 22 of inverted T shape, and described opening 22 has the top smaller opening and below comparatively big uncork (not indicating in figure) that are interconnected.
In another embodiment, the width of the top smaller opening of described opening 22 is X
1, namely equal the width of described body 11; The below of described opening 22 is X compared with the width of big uncork
2, namely equal the width of body 11 together with two fasteners 13; The length of the top smaller opening of described opening 22 is Y
1, namely equal the length of described fastener 13; The top smaller opening of described opening 22 and below are Y compared with the intersection of big uncork and the distance of described pad 21
2, namely equal the distance of fastener 13 and electroplate lead wire 12.
Finally, please as shown in Figure 3, it is structural representation backlight golden finger according to the present invention and main FPC welded together.The workflow of a kind of FPC structure provided by the present invention is: when welding, first by backlight golden finger 1 away from one end of electroplate lead wire 12 from the bottom to top through the inverted T shape opening 22 of main FPC2, when two fasteners 13 are through the below of opening 22 comparatively after big uncork, fastener 13 is just in time stuck in the top smaller opening of opening 22 and the below intersection compared with big uncork.Due to the width X of the top smaller opening of described opening 22
1equal the width of described body 11, the below of described opening 22 is compared with the width X of big uncork
2equal the width of body 11 together with two fasteners 13, the length Y of the top smaller opening of described opening 22
1equal the length of described fastener 13, and the top smaller opening of described opening 22 and the below intersection compared with big uncork and the distance Y of described pad 21
2, equal the distance of fastener 13 and electroplate lead wire 12.Each corresponding size relation above, can accurately ensure the fastener 13 of described backlight golden finger 1 engage by the opening 22 of described inverted T shape, and the electroplate lead wire 12 of backlight golden finger 1 and pad 22 contraposition completely of main FPC2 can be ensured, realize good welds, there will not be contraposition unfavorable condition.
In another embodiment, the shape of described opening 22 can be trapezoidal, triangle etc., as long as it is spacing with coordinating of fastener 13 to realize opening 22, thus the electroplate lead wire 12 realized on backlight golden finger 1 and pad 21 contraposition completely.Such as, when the shape of opening 22 is trapezoidal, need to ensure that two trapezoidal parallel edges are vertical with the bearing of trend of the backlight golden finger 1 that will insert, and trapezoidal maximum parallel edges needs the width X of the body 11 being greater than described backlight golden finger 1
1, and trapezoidal minimum parallel limit needs to be more than or equal to the width X of described body 11 together with two fasteners 13
2, the opening 22 of this shape can realize the locking of the fastener 13 to described backlight golden finger 1 equally.When the shape of opening 22 is triangle, the locking of the fastener 13 to described backlight golden finger 1 in like manner also can be realized.
In addition, in another embodiment, described opening 22 can also be slit, and the length of described slit can make the body 11 of described backlight golden finger 1 pass, and coordinate spacing with described fastener 13, thus the electroplate lead wire 12 realized on backlight golden finger 1 and pad 21 contraposition completely.
It should be noted that, the shape of opening 22 is not limited to listed example herein.
In sum, the invention has the beneficial effects as follows: compared to existing technology, welding engineer's contraposition when welding backlight FPC can be made more simply and not easily to make mistakes by the present invention, and the alignment mark on main FPC2 can also be saved by the present invention, thus save contraposition and identify one processing procedure, accelerate the course of processing, thus produce considerable economic benefit.
