Abstract
The present utility model discloses a golden finger pad which comprises at least a first pad and at least a second pad, the first pad and the second pad are staggered, the edge of a transition segment of a relative wide edge and a relative narrow edge of the first pad is arc-shaped, and the edge of a transition segment of a relative wide edge and a relative narrow edge of the second pad is also arc-shaped. In the golden finger pad, as the transition segments of the relative wide edges and the relative narrow edges of the first and second pad are designed as arc-shaped, when the pas is bent or plugged, stressing points of the whole golden finger pas are dispersed on various positions with arc corners instead of a straight line. Thus, risks that the pad is easily broken after being plugged and bent for many times can be greatly reduced.
Description
Technical field
The utility model relates to the pad design of golden finger, particularly a kind of golden finger pad.
Background technology
Diversified development along with mobile phones design; The application of FPC (FPC) on mobile phone also more and more widely; The connector of ZIF (the zero resistance insert) way of contact is because the PIN pin is arranged closely, and it is little to take up room, also increasing being used in being connected of mainboard and FPC.
See also Fig. 1; It is a prior art golden finger Welding Structure sketch map; Said golden finger pad comprises a plurality of first pads 11 and a plurality of second pads 12; These first pads 11 and second pad 12 are crisscross arranged, and the turnings of first pad 11 and second pad 12 periphery are broken line, and be as shown in the figure.Because the PIN pin of this golden finger pad is arranged closely (lead pin pitch that 0.3mm is generally only arranged), this has increased the difficulty of golden finger pad encapsulation greatly.And this golden finger pad configuration, the sharp-pointed pin that the turning at its edge is made up of broken line makes the thickness joining place of each pad not have transition; Like this, when pad is squeezed or bend, in its application sets point-blank; Make in the golden finger pad encapsulation process,, push in repeatedly plug; After falling, the golden finger fracture appears in the corner of metal finger (dotted line place as shown in Figure 1) easily, causes whole FPC to scrap.
In view of this, be necessary the pad structure of golden finger is improved.
Summary of the invention
In view of the weak point of above-mentioned prior art, the purpose of the utility model is to provide a kind of golden finger pad, to solve the prior art golden finger pad problem of fracture easily.
In order to achieve the above object, the utility model has been taked following technical scheme:
A kind of golden finger pad, it comprises at least one first pad and at least one second pad, and said first pad and second pad are crisscross arranged, and wherein, the relative broadside of said first pad is curved with the edge of the changeover portion on narrow relatively limit; The relative broadside of said second pad is curved with the edge of the changeover portion on narrow relatively limit.
Described golden finger pad; Wherein, Said first pad comprises first, second portion, third part and the 4th part; The width of said first is than the narrow width of second portion, and the width of second portion is wideer than the width of third part, and the width of third part is than tetrameric narrow width.
Described golden finger pad, wherein, the width at the two ends of said second pad is than middle narrow width.
Described golden finger pad, wherein, the spacing of said first pad and second pad is 0.1mm.
Described golden finger pad, wherein, the width of said second pad is 0.25mm.
Compared to prior art; The golden finger pad that the utility model provides; Owing to adopted the relative broadside of first pad and second pad and the changeover portion on narrow relatively limit are designed to arc; By bending, when plug, the stress point of whole golden finger pad is distributed to each position at radian turning at pad, rather than point-blank.Repeatedly plug the risk that the bending back is fractureed thereby greatly reduce pad.

The golden finger pad configuration sketch map that Fig. 1 provides for prior art.
The golden finger pad configuration sketch map that Fig. 2 provides for this practicality.
Fig. 3 is the utility model first pad configuration sketch map.
Fig. 4 is the structural representation of the utility model one application implementation example.
Embodiment
The utility model provides a kind of golden finger pad, for purpose, technical scheme and the effect that makes the utility model is clearer, clear and definite, below develops simultaneously embodiment to the utility model further explain with reference to accompanying drawing.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 2, the golden finger pad that the utility model embodiment provides comprises at least one first pad 10 and at least one second pad 20, and said first pad 10 and second pad 20 are crisscross arranged.Wherein, the relative broadside of said first pad 10 is curved with the edge of the changeover portion on narrow relatively limit; The relative broadside of said second pad 20 is curved with the edge of the changeover portion on narrow relatively limit.Present embodiment adopts rounding off with the edge transition section of first pad 10 and second pad 20; Make the stress point of whole golden finger pad be distributed to each position at radian turning; Rather than, repeatedly plug the risk that the bending back is fractureed point-blank thereby greatly reduce pad.
Please consulting Fig. 3 in the lump, below serves as concrete practical example with first pad 10, and the golden finger pad configuration of the utility model is elaborated.
As shown in the figure; First pad 10 comprises first 101, second portion 102, third part 103 and the 4th part 104; The width of said first 101 is than the narrow width of second portion 102; The width of second portion 102 is wideer than the width of third part 103, and the width of third part 103 is than the narrow width of the 4th part 104.And; In first 101, second portion 102, third part 103 and the 4th part 104; Edge with the transition portion 105,106,107 of the linking section of various piece is arc camber turning respectively; Make the stress point of the pad 10 of winning be distributed to each position at radian turning, rather than point-blank.
Please consult Fig. 1 once more, the width at the two ends of said second pad 20 is than the narrow width of mid portion, and the changeover portion edge of its two ends and mid portion is also curved.In the present embodiment, the space D 1 of said first pad 10 and second pad 20 is 0.1mm, and the width D 2 of said second pad is 0.25mm.
See also Fig. 4, the routine sketch map of the application implementation of golden finger pad in the ZIF interface that it provides for the utility model.As shown in the figure, golden finger pad design curve is slick and sly, makes the gentle transition of thickness joining place; Not only improved the anti-ability of fractureing of pad; And increased the whole toughness of pad more, become a kind of perfect structure of such golden finger pad, and in right amount in production in enormous quantities.
In sum; The golden finger pad that the utility model provides; Owing to adopted the relative broadside of first pad and second pad and the changeover portion on narrow relatively limit are designed to arc; By bending, when plug, the stress point of whole golden finger pad is distributed to each position at radian turning at pad, rather than point-blank.Repeatedly plug the risk that the bending back is fractureed thereby greatly reduce pad.
It is understandable that, concerning those of ordinary skills, can be equal to replacement or change according to the technical scheme and the utility model design thereof of the utility model.
