Embodiment
See also Fig. 1, Fig. 1 is the exploded view that illustrates according to the keyboard 3 of the utility model one first specific embodiment.As shown in Figure 1, keyboard 3 of the present utility model comprises button 30, base plate 32, film circuit board 36 and film winding displacement 38.Button 30 is positioned on the base plate 32, and is attached to base plate 32.Base plate 32 corresponding button 30 parts have a through hole, allow elastomer 34 pass through.Film circuit board 36 is positioned at base plate 32 times, and elastomer 34 is positioned on the film circuit board 36.When user's pressing keys 30, button 30 can compressing elastomer 34.Then, elastomer 34 compressing film circuit boards 36, the switching circuit of film circuit board 36 produces the electronic signal of corresponding button 30 at last because of the compressing conducting.
Generally speaking, the junction between film winding displacement 38 and the film circuit board 36 need have certain-length and width to hold the corresponding circuits of the numerous buttons 30 on the keyboard 3, and then film winding displacement 38 will certainly extend a segment distance from film circuit board 36.When the joint (not illustrating) of electronic component was positioned at film circuit board 36 belows, film winding displacement 38 must bend to cooperate the position of joint.And how film winding displacement of the present utility model overcomes the winding displacement splintering problem that bending action causes, and sees also Fig. 2 A and Fig. 2 B.
Fig. 2 A is the schematic diagram before film winding displacement 38 bendings that illustrate among Fig. 1.Fig. 2 B is the schematic diagram after film winding displacement 38 bendings that illustrate among Fig. 1.Shown in Fig. 2 A and Fig. 2 B, film winding displacement 38 of the present utility model comprises a plurality of metal wires 380, cladding 382 and first reinforced sheet 386.Cladding 382 coats the outer surface 3820 that these a plurality of metal wire 380, the first reinforced sheets 386 are attached at cladding 382.Cladding 382 and these a plurality of metal wires 380 are towards 386 bendings (shown in the direction of arrow) of first reinforced sheet.
In fact, the outer surface 3820 of cladding 382 comprises the lower surface 3824 that upper surface 3822 reaches with respect to upper surface 3822.First reinforced sheet 386 is attached at lower surface 3824, the first sign lines 384 and is printed in upper surface 3822 and roughly corresponding the subsides together in the edge of first reinforced sheet 386.The purpose that indicates line is when allowing the processor manually bend film winding displacement 38, can determine the bending place apace.Therefore, the processor can promptly bend film winding displacement 38 according to the first sign line 384 that is printed in upper surface 3822 towards first reinforced sheet 386, can reduce trial and error (try-and-error) number of times in order to look for correct bending place.The number of times that film winding displacement 38 is bent is few more, just can reduce also that cladding 382 or metal wire 380 break or the possibility of breakage problem.
In addition, when the cladding 382 of part when the bending of first reinforced sheet 386 (toward inner bending), because first reinforced sheet 386 has a thickness, therefore the bending path of cladding 382 can be stopped by first reinforced sheet 386 and reduce maximum bending angle, and therefore first reinforced sheet 386 can be avoided film winding displacement 38 overflexings.
Because first reinforced sheet 386 itself also has certain shape, the edge of first reinforced sheet 386 can paste neat with the first sign line 384, when therefore bending film winding displacement 38, except indicating line 384 bendings along first, also can look for correct folding line by the edge that touches first reinforced sheet 386, but that is the effect of first reinforced sheet, 386 assist location folding lines, and then promote assembling speed.
Be noted that cladding 382 among Fig. 1 and metal wire 380 can only be towards lower surface 3824 bendings of posting first reinforced sheet 386.Because upper surface 3822 does not post first reinforced sheet 386, therefore first reinforced sheet 386 also can't reduce towards the maximum bending angle of upper surface 3822 bendings, thereby can not avoid the function of film winding displacement 38 overflexings.
The upper surface 3822 of the cladding 382 among Fig. 1 is printed with in addition between the second sign line, 385, the first sign lines 384 and the second sign line 385 and posts first reinforced sheet 386.So film winding displacement 38 also can be according to the second sign line 385, towards 386 bendings of first reinforced sheet.Thus, film winding displacement 38 bendables among Fig. 1 are converted into inverted u-shaped.
Certainly, film winding displacement of the present utility model is not limited to the embodiment aspect among Fig. 1, also can will be specified in down as shown in Figures 3 and 4.
See also Fig. 3, Fig. 3 is the schematic diagram that illustrates according to the film winding displacement 58 of the utility model one second specific embodiment.Be compared to Fig. 2 A and Fig. 2 B, the film winding displacement more than 58 of Fig. 3 second reinforced sheet 587 and the 3rd reinforced sheet 588.First reinforced sheet 586, second reinforced sheet 587 and the 3rd reinforced sheet 588 all are attached at the lower surface 5824 of cladding 582, indicate line 584 at interval with first between second reinforced sheet 587 and first reinforced sheet 586, indicate line 585 at interval with second between the 3rd reinforced sheet 588 and first reinforced sheet 586.First indicates line 584 and second indicates the upper surface 5822 that line 585 all is printed in cladding 582.
Thus, desire to indicate line 584 or second when film winding displacement 58 and indicate line 585 bendings along first, and desire when 586 bendings of first reinforced sheet, second reinforced sheet 587 or the 3rd reinforced sheet 588 can contact with first reinforced sheet 586, therefore stop the bending path, therefore can further reduce maximum bending angle.
See also Fig. 4, Fig. 4 is the schematic diagram that illustrates according to the film winding displacement 78 of the utility model 1 the 3rd specific embodiment.Compared to Fig. 3, upper surface 7822, the second reinforced sheets 787 and the 3rd reinforced sheet 788 that first reinforced sheet 786 among Fig. 4 is attached at cladding 782 all are attached at lower surface 7824.
Because upper surface 7822 and lower surface 7824 all have reinforced sheet to attach, therefore the film winding displacement 78 of the 3rd embodiment is not limited to towards upper surface 7822 or lower surface 7824 bendings.In other words, film winding displacement 78 not necessarily will be followed the direction of arrow bending among the figure among Fig. 4, also can oppositely bend, and can satisfy the overbending direction of different product design thus.
In the 3rd embodiment, because overbending direction is not limit, therefore the first sign line 784 and second indicates line 785 except the upper surface 7822 that is printed in cladding 782, the preferable practice is also to be printed in lower surface 7824 (owing to the visual angle problem of Fig. 4, and can't show the situation that is printed in lower surface 7824).Thus, if processor's desire will be pasted with the part cladding 782 of the 3rd reinforced sheet 788 towards 786 bendings of first reinforced sheet, then can be according to the second sign line (not showing) that is printed in lower surface 7824, and need not rotate the position that film winding displacement 78 is watched the second sign line 785 that is printed in upper surface 7822, thereby printed on both sides sign line can further increase the assembling convenience.
Be compared to prior art, the utility model indicates the bending place by marking line, allows the processing personnel can With according to marking line, correctly bend film drop-out line and accelerate assembling speed and reduce in order to locate the bending place Trial bending number of times. In addition, the utility model reduces bending by the reinforced sheet of being close to cladding Angle, but and the assist location bending place, so reinforced sheet can avoid film drop-out line because of bend excessive or The bending number of times too much and the cladding splintering problem that produces. So the utility model has solved prior art In the excessive and problem that causes cladding to break of film drop-out line bending angle, and solved in the process Be not easy to locate the bending place and cause number of times that cladding bent too much and the problem of damaging.
