Embodiment
Below, with reference to accompanying drawing, the example of the execution mode of small diameter coaxial cable bunch involved in the present invention and manufacture method thereof is described.As shown in Figures 1 and 2, in the present embodiment, between two substrates 11,12 that dispose overlappingly up and down, (left and right directions of Fig. 1, Fig. 2) move horizontally forwards, backwards, connect by the small diameter coaxial cable bunch 20 that comprises many (20～60) small diameter coaxial cables 24. Substrate 11,12 is installed in respectively in the framework of the slide relative of equipment such as mobile phone for example.Two ends of small diameter coaxial cable bunch 20 are carried out to end by mounted connector 25 and handle, and become easy thereby make with being connected of substrate 11,12.In addition, small diameter coaxial cable bunch 20 utilizes through compiling cover 23 many small diameter coaxial cables 24 is tied up except both ends 21a, 21b.In addition, small diameter coaxial cable bunch 20 is connected with two substrates 11,12, forms U word shape (perhaps J word shape) (with reference to Fig. 1 (A) and Fig. 2 (A)) on the direction as a whole overlooking of substrate 11,12.Thus, can between two substrates 11,12, carry out distribution to small diameter coaxial cable bunch 20.In addition, Fig. 1 is both ends 21a, the 21b distance state farthest of small diameter coaxial cable bunch 20, and Fig. 2 is the immediate state of both ends 21a, 21b.Relative movement distance on the horizontal direction of substrate 11,12 is for example from the degree of 30mm to 60mm.
Small diameter coaxial cable 24 constitutes, with the section radially of orthogonality of center shaft on, therefrom the mind-set outside has center conductor, internal insulator, external conductor and crust, on each end 21a, 21b, implement terminal the processing, external conductor, internal insulator, center conductor steppedly are exposed with specific length respectively.In addition, in small diameter coaxial cable bunch 20, except many small diameter coaxial cables, can comprise does not have the thin footpath of external conductor insulated cable yet.In addition, in the accompanying drawings, the radical of small diameter coaxial cable 24 less is shown and simplifies.
Observe in vertical view, small diameter coaxial cable bunch 20 is to Width (direction of the double-head arrow W among Fig. 1 (the A)) bending of substrate.Because the width of substrate 11,12 is several cm, so can guarantee the bending diameter of this direction fully.For example, shown in Fig. 1 (A), if an end 21a of small diameter coaxial cable bunch 20 is connected with the right side (being upside in Fig. 1 (A)) of upper substrate 11 when observing on Width W, another end 21b is connected with the left side (being downside in Fig. 1 (A)) of infrabasal plate 12 when then observing on Width W.Small diameter coaxial cable bunch 20 bends to U word shape, but in order to reduce to be used to accommodate the space of small diameter coaxial cable bunch 20, makes the width (interval of straight line portion) of U word narrow more good more.
In the structure of Figure 1 and Figure 2, use under the situation of FPC (flexible printed board) replacing small diameter coaxial cable bunch 20, because FPC is between two substrates 11,12, with the direction of the in-plane quadrature of substrate on crooked, so must increase the gap of two substrates 11,12 in order to ensure its bending diameter.To this, in the present invention, the gap of two substrates 11,12 is that the thickness degree of small diameter coaxial cable bunch 20 gets final product, and does not need as under the situation of using FPC big gap to be set, and can realize the slimming of equipment.
As small diameter coaxial cable 24, preferably use the thin superfine coaxial cable of comparing with the AWG44 of for example AWG (American WireGauge) specification, perhaps external diameter is less than the coaxial cable of 0.30mm.Thus, small diameter coaxial cable bunch 20 is crooked easily, the resistance in the time of can reducing two substrates 11,12 slide relative.In addition, when forming small diameter coaxial cable bunch 20, can make the thickness H1 (with reference to Fig. 3 (C)) of small diameter coaxial cable bunch 20 form thinlyyer, can realize the slimming of equipment in that many small diameter coaxial cables 24 are tied up.Owing to also small diameter coaxial cable bunch 20 can be utilized substrate 11,12 clampings and extruding, and carry out flattening, so also can make the gap between the substrate 11,12 omit (0.2mm degree) thickness less than small diameter coaxial cable bunch 20.As noted above, in small diameter coaxial cable bunch 20, can comprise does not have the thin footpath of external conductor insulated cable yet, but preferably should use the cable of external diameter less than 0.30mm by thin footpath insulated cable.
Small diameter coaxial cable bunch 20 comprises for example small diameter coaxial cable from 40 to 50 degree 24.If adopt form profile diameter under the state cylindraceous be less than or equal to 2.5mm, through compile thickness be less than or equal to 0.1mm through compiling cover 23, then the cable of above-mentioned radical can be tied up.Be less than or equal to for the fineness of AWG46 or external diameter at small diameter coaxial cable 24 under the situation of fineness of 0.27mm, if approach the bunch of cables of round shape and form small diameter coaxial cable bunch 20 (also can comprise thin footpath insulated cable) as section, the thickness that then comprises through compiling cover 23 is less than or equal to 1.5mm at the external diameter (thickness) of interior small diameter coaxial cable bunch 20.Therefore, can in the receiving space of 1.5mm height (thickness), carry out distribution to small diameter coaxial cable bunch 20.If this small diameter coaxial cable bunch 20 is configured to U word shape, the width of this U word is dropped in the 10mm to 16mm.Along with the width of the increase U word of core number (radical of small diameter coaxial cable 24) also broadens, even but tie up the small diameter coaxial cable 24 of 60 AWG44, the width of its U word is dropped in the 18mm.
As shown in Figure 1 to Figure 3, small diameter coaxial cable bunch 20 is tied up formation by many small diameter coaxial cables 24 are passed in compiling cover 23, for example shown in Fig. 3 (C), is preferably formed flat oval-shaped profile and makes the as far as possible little shape of gauge H1 like this.Cover many small diameter coaxial cables 24 by utilizing, improve the durability of the friction of small diameter coaxial cable bunch 20 with respect to the time with the wall slide relative of substrate 11,12 etc. through compiling cover 23.In addition, in small diameter coaxial cable bunch 20, will sectional area (also comprising inboard space) be made as through compiling cover 23 greater than the sectional area of small diameter coaxial cable 24 and, and tie up small diameter coaxial cable than loose ground, therefore, small diameter coaxial cable 24 is overlapping actions such as being easy to carry out permutations in 23 through compiling.
Even relatively move in the horizontal direction with the substrate 11,12 that the two ends of small diameter coaxial cable bunch 20 are connected respectively, the part of tying up of small diameter coaxial cable bunch 20 is out of shape repeatedly together therewith, also owing in compiling cover 23, can relatively move between many small diameter coaxial cables 24, therefore, the bending load that applies to small diameter coaxial cable 24 is integrally discharged easily, thereby do not apply excessive load to small diameter coaxial cable 24.Therefore, even small diameter coaxial cable bunch 20 is out of shape repeatedly, also can prevent the fracture of the center conductor of small diameter coaxial cable 24.
In the present embodiment through compile cover 23 be with synthetic fibers carry out forming through volume tubular through compiling cover.As synthetic fibers, the preferred monofilament composite fibre of using the fiber that forms by polyethylene terephthalate polyester such as (PET) or constituting by core composition that forms with the fusion liquid-crystalline polymer and the sheath composition that contains the bendability polymer.
Here, for 1 synthetic fibers, its hot strength is more than or equal to 3.0cN/dtex, and its fibre diameter is less than or equal to 60 μ m more than or equal to 30 μ m, and is thin and intensity is higher.For example, the hot strength of wool is less than 1.5cN/dtex, and the hot strength of artificial silk is less than 2.5cN/dtex, but the synthetic fibers that use in the present invention specific tensile strength is bigger mutually with them.
In addition, in the volume mode, have as elementary organization: warp plain stitch braiding (denbighstitch), through suede tissue (plain cord stitch), traverse tricot weave (atlas stitch) and pillar stitch (chain stitch) etc., they all form a plurality of wire loops by braiding.
In addition, above-mentioned synthetic fibers are overlapped 23 through compiling to what tubular formed through compiling, its thickness is less than or equal to 0.1mm.
In addition,, use plan shape (dummy) core of section as ellipse if when braided fiber, the plan shape core of many sections that use perhaps arranged side by side as circle, braided fiber around it then produces section and is oval overlapping through compiling.
Said structure superior through compiling cover 23 mar proofs and intensity uses these small diameter coaxial cable bunch 20 bendabilities through compiling cover 23 good, and not can owing to and the framework of substrate 11,12 etc. or electronic equipment between repeated friction make through compiling cover 23 breakages.Therefore, even small diameter coaxial cable 24 alternating bendings also can prevent the center conductor fracture, and, can keep the state that many small diameter coaxial cables 24 are tied up chronically.
Utilize splicing tape (teflon (registered trade mark) adhesive tape) to tie up and put under the situation of highly sliding at for example 40 small diameter coaxial cables 24 of AWG46 thickness for the gap of 2.4mm, through 80,000 times crooked and slip, center conductor ruptures repeatedly.On the other hand, overlapping under 23 situations of tying up in utilizing present embodiment through volume, even after carrying out 100,000 times bending repeatedly and sliding, center conductor does not rupture yet.
If utilize constraints such as splicing tape and tie up small diameter coaxial cable 24, then difficult distortion (being difficult to flattening) of the section shape of this part, but small diameter coaxial cable 24 is tied up by using through compiling cover 23, can make many small diameter coaxial cables 24 with moving along direction in the section, make the part of tying up suitably carry out flattening accordingly with receiving space through compiling cover 23.Even for example making through compiling the diameter that cover 23 forms when cylindric is 2.5mm, also can be by carrying out flattening accordingly with the space, and become the thickness (minor axis of the ellipse after flat) that is less than or equal to 1.5mm.Also can use the sort of section overlapping as flat pattern through compiling.Prepare the small diameter coaxial cable 24 of 40 AWG46 thicknesses, utilizing diameter to be it is tied up in the present embodiment of 2.5mm through compiling cover 23, and put into height and bend under the situation that U word shape slides for the gap of 1.5mm, even after carrying out 200,000 times bending repeatedly and sliding, center conductor is not fracture also.On the other hand, under the situation of utilizing splicing tape to tie up, because diameter is 1.8mm, so can't put into the gap of 1.5mm.
When making small diameter coaxial cable bunch 20, shown in Fig. 4 (A), small diameter coaxial cable 24a short in the many small diameter coaxial cables 24 that length is different is configured in central authorities, disposes long small diameter coaxial cable 24b successively to the end, is that equally spaced mode is arranged with end 21a, 21b.And, Yi Bian utilize film or anchor clamps etc. to keep these ordered states, center conductor and external conductor are exposed steppedly on one side from the end of small diameter coaxial cable 24, carry out end and handle, and further be connected and be carried out to and hold processing with connector 25.
In the present embodiment through compiling cover 23, at the state that is not stretched (for example, at the section internal diameter under the state cylindraceous is under the situation of 1.5mm, when the plug of 1.4mm is inserted) under count be, on Width, be less than or equal to 75/inch of number of rings, be less than or equal to 35/inch of number of rings more than or equal to 25/inch of number of rings in the longitudinal direction more than or equal to 55/inch of number of rings.By such count, can easily the two ends through compiling cover 23 be enlarged, connector 25 and small diameter coaxial cable 24 are passed through.As shown in Figure 5, make through compiling cover 23 to tighten in the longitudinal direction,, connector 25 is passed through wherein simultaneously with the enlarged-diameter of an end.The internal diameter of for example 1.5mm can be extended to internal diameter through volume cover 23 is 5mm.Therefore, can easily make the many small diameter coaxial cables 24 of Belt connector by overlapping in 23 after the hole enlargement through compiling.In addition, even in the longitudinal direction, also can stretch with the expansion and contraction of 5% to 15% degree.
Thus, shown in Fig. 4 (B), can form utilization through compiling the small diameter coaxial cable bunch 20 that cover 23 is tied up mid portion.In addition, because the small diameter coaxial cable 24a that will relatively lack is configured in central authorities, and long small diameter coaxial cable 24b is configured in side, so when making small diameter coaxial cable bunch 20 bendings, when being difficult for applying bending or the tension force when reversing, can prevent the fracture of center conductor.Preferably make connector 25 and small diameter coaxial cable 24, utilizing splicing tape etc. to fix, so that can not relax and hold through compiling cover 23 through the two ends of compiling cover 23 by after compiling cover 23.Also can utilize the sticking card in end that splicing tape etc. will be through compiling cover 23 and be fixed on the small diameter coaxial cable 24.
At this moment, if (on Width, surpass 75/inch of number of rings, surpass in the longitudinal direction perhaps that 35 of number of rings/inch), then thickness increases, make thickness can't satisfy 0.1mm through the count of compiling is excessive through compiling cover.If too small through the count of compiling, then be loose state through weaving into, be difficult to keep through compiling the state of cover, when reversing, the small diameter coaxial cable 24 of insertion may protrude to the outside between the synthetic fibers through compiling.In addition, if count is too small (on Width less than 55/inch of number of rings, perhaps in the longitudinal direction less than 25 of number of rings/inch), then be difficult to stretch, can't make through compiling cover 23, be difficult to make the connector 25 that is installed on the small diameter coaxial cable 24 to pass through fully to circumferential hole enlargement.
Small diameter coaxial cable bunch 20 in the present embodiment through compiling cover 23, the fibre diameter that is synthetic fibers is less than or equal to 60 μ m more than or equal to 30 μ m, thickness through compiling is less than or equal to thin the overlapping through compiling of 0.1mm, and, the hot strength of synthetic fibers is more than or equal to 3.0cN/dtex, with respect to crooked, slide and the tolerance reversed stronger.And, owing to its count is less than or equal to 75/inch of number of rings more than or equal to 55/inch of number of rings on Width, be less than or equal to 35/inch of number of rings more than or equal to 25/inch of number of rings in the longitudinal direction, so can circumferentially and on the length direction stretch well through compiling cover 23, can make through compiling and overlap 23, thereby the connector 25 that is installed on the small diameter coaxial cable 24 is passed through to circumferentially hole enlargement fully.And, can keep state well through compiling, can not produce to make to pass and overlap the problem that the small diameter coaxial cable 24 in 23 protrudes to the outside at the eyelet that reverses the Shi Congjing volume through volume.In addition, owing to adopt above-mentioned count, and thickness is made as is less than or equal to 0.1mm, so small diameter coaxial cable 24 can not tightened through compiling cover 23.
In addition, under the fixed situation of the bending direction of small diameter coaxial cable bunch 20, if in the small diameter coaxial cable of arranging equally spacedly 24, at the relatively shorter small diameter coaxial cable 24a of the side configuration of orientation, form bunch of cables at the opposite side long small diameter coaxial cable 24b of configuration, and, then can reduce the load that causes by bending on the whole effectively at the short small diameter coaxial cable 24a of the inboard of bending configuration.
In addition, in the above-described embodiment, mounted connector 25 on the end of small diameter coaxial cable bunch 20 21a, 21b has been described and is carried out to the situation that end is handled, but the one-tenth end that also can implement other is handled.
The connector 25 that also can replace above-mentioned explanation makes the end of small diameter coaxial cable bunch 20 be connected with FPC (Flexible Printed Circuits), and FPC is installed on the substrate 11,12.Even in these cases, also the bore of the end through compiling cover 23 can be enlarged, small diameter coaxial cable 24 is easily passed through through compiling cover 23.In addition, in small diameter coaxial cable bunch of the present invention, can suitably mix the insulated electric conductor that does not have external conductor.Insulated electric conductor can be used as earth connection, perhaps insulated electric conductor be used as supply lines.
In addition, small diameter coaxial cable bunch 20 also can use in the distribution in the equipment except the framework of slide relative.For example, as shown in Figure 6, also can be installed in and make between the framework in relative rotation in the equipment such as mobile phone and use.In the example of Fig. 6, in the framework 32 of non-moving side, form straight-line groove 32a and curved groove 32b, in these grooves 32a, 32b, embed pin 31a, 31b on the framework 31 that is arranged on mobile side.When framework 31 moves, from the state shown in Fig. 6 (A), framework 31 follows moving of pin 31a to carry out displacement upward, and, follow moving in the counterclockwise direction of pin 31b to rotate, state via Fig. 6 (B), framework 31 follows moving of pin 31a to carry out displacement downwards, and, follow moving of pin 31b, further rotate in the counterclockwise direction, become the state of Fig. 6 (C).Thus, framework 31 is revolved with respect to framework 32 and is turn 90 degrees.At this moment, the small diameter coaxial cable bunch 20 that is connected for the substrate with the substrate of framework 31 and framework 32 and does not move near the end 21b that framework 32 is connected, and the end 21a that is connected with framework 31 carries out displacement up and down and rotates 90 and spend.By carrying out action and the counteragent thereof of Fig. 6 (A) to (C) repeatedly, in small diameter coaxial cable bunch 20, near the part of end 21a is by alternating bending, and in framework 31,32, slide, but small diameter coaxial cable 24 is moving in the mode that discharges load in compiling cover 23, can prevent the center conductor fracture.In addition, also can prevent through compiling cover 23 owing to friction damages.
In addition, as other example, as shown in Figure 7, small diameter coaxial cable bunch 20 also can be installed in and utilize in the equipment such as mobile phone that hinge links between the end with framework rotationally and use.In mode shown in Figure 7, have the mobile telephone terminal 40 of the 1st framework 41 and the 2nd framework 42, utilize small diameter coaxial cable bunch 20 that the 1st framework 41 and the 2nd framework 42 are connected.In mobile telephone terminal 40, utilize hinge 44 to link between the end with the 1st framework 41 and the 2nd framework 42 rotationally, make the position relationship change by switching.The 1st framework 41 and the 2nd framework 42 form cable patchhole 45,46 respectively on it links the end face of side, from these cable patchholes 45,46 two ends of small diameter coaxial cable bunch 20 are imported respectively.In addition, on hinge 44, form intercommunicating pore 44a, in this intercommunicating pore 44a, insert small diameter coaxial cable bunch 20.Even the 1st framework 41 and the 2nd framework 42 relatively rotate repeatedly by hinge 44, not yet can not damaging of small diameter coaxial cable bunch 20 because of friction through compiling cover 23, small diameter coaxial cable 24 is moving in the mode that discharges load in compiling cover 23, and center conductor can not rupture.
