Embodiment
Relevant the utility model is for reaching above-mentioned purpose, and technological means that is adopted and effect thereof are lifted preferred embodiment now, and cooperate graphic be illustrated as follows.
Please refer to Fig. 2, for using the CD-ROM drive 10 of the utility model soft rowed line structure.CD-ROM drive 10 comprises casing 11, pallet 12, main circuit board 13 and soft arranging wire 14.Be mainly hollow casing 11 can allow pallet 12 be free to slide turnover, soft arranging wire 14 1 ends are connected in the rear end of pallet 12, the other end then connects the main circuit board 13 that is located at casing 11 rear ends, makes pallet 12 and main circuit board 13 when relative position changes, but transmission signals still.
Wherein, casing 11 is made of upper casing 15 (please join Fig. 3) and lower casing 16, and upper casing 15 forms hollow form with lower casing 16, and a guide rail 17 is respectively established in the both sides of lower casing 16, then establishes main circuit board 13 by rear side, and the front end of main circuit board 13 is provided with a connector 18.In the support of pallet 12 two side ends limits by guide rail 17, extended or retraction casing 11, change or play discs.Pallet 12 centers are provided with a Spindle Motor 19, in order to rotating disc sheet 20 (please join Fig. 3).Pallet 12 is provided with a read head 21 in addition, can be along the moving radially of discs, with the data of writable disc sheet.By the secondary circuit board 24 (please join Fig. 3) of pallet 12 belows, control the running of Spindle Motor 19 and read head 21 again.
In addition, as shown in Figure 3, sectional side view by CD-ROM drive 10 shows, movable part 23 is extended by the end that fixed part 22 is positioned at casing 11 front opening places, preceding a bit of reflexed section 25 reflexeds are to casing 11 inside, stacked and be fixed on fixed part 22 upper surfaces, 23 of the movable parts that continues are not fixed, it only is the top that inwardly is suspended in fixed part 22 merely, the other end of last flexion portion 23 is connected in the rear side of pallet 12, just connect the secondary circuit board 24 that is positioned at pallet 12 bottoms, make main circuit board 13, be electrically connected with secondary circuit board 24 generations via soft arranging wire 14.The length of movable part 23 is also looked closely the displacement of pallet 12 and is decided, and its length just allows pallet 12 enter play position and gets final product, and the long CD-ROM drive 10 that then can influence operates.
Therefore, after soft arranging wire 14 of the present utility model utilizes injection mo(u)lding easy to manufacture and with low cost, be pre-formed reflexed section 25, can simply be connected in main circuit board 13, and fixed part 22 be sticked in the surface of lower casing 16, again movable part 23 1 ends are connected in pallet 12 and finish and assemble with viscose, avoid using expensive printed circuit traces, and can simplify the man-hour and the cost of CD-ROM drive assembly, to reduce the CD-ROM drive cost, improve competitiveness of product.
In addition, refer again to Fig. 3, the utility model soft arranging wire 14 structures are when running, because of connecting the mode of pallet 12 and reflexed section 25, make the movable part 23 of soft arranging wire 14, when pallet 12 shifts out CD-ROM drive 10, by the elasticity of soft arranging wire 14 itself, allow the activity 23 of soft arranging wire 14 bendings be positioned at the rear of pallet 12, the unlikely CD-ROM drive 10 that exposes.When pallet 12 progresses into CD-ROM drive 10, under the fixing of soft arranging wire 14 fixed parts 22 and the guiding of reflexed section 25 reflexeds, make movable part 23 along with pushing away in the pallet 12, flat naturally crawl is in the top of fixed part 22.When pallet 12 enters play position, as shown in Figure 4, the length of pallet 12 just can be kept movable part 23 1 ends of holding soft arranging wire 14, at movable part 23 other ends is under the fixing situation of fixed part 22, can make movable part 23 be tiled in the upper surface of fixed part 22, allow the overlapping thickness of soft arranging wire 14, still can be in the space of 16 of pallet 12 lower casings, and the unlikely bottom that touches pallet 12, avoid soft arranging wire 14 friction that is squeezed, reduce and damage soft arranging wire 14, can prevent to hinder simultaneously the running of CD-ROM drive 10.And soft arranging wire 14 is with fixing reflexed section 25, and is not only bootable and force down soft arranging wire 14, do not influence the thickness of CD-ROM drive, also can reach the purpose of avoiding the soft arranging wire repeated flex and damaging.
