Embodiment
Below, on one side 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 on one side.
At first, utilize Fig. 1～9 explanation the first execution modes.
As shown in Figures 1 and 2, in the present embodiment, configuration overlappingly and (left and right directions of Fig. 1, Fig. 2) two substrates 11,12 of moving horizontally are up and down forwards, backwards connected by the small diameter coaxial cable bunch 20 that comprises many (20～60) small diameter coaxial cables 24. Substrate 11,12 is such as in the housing that carries out relative sliding that is respectively charged into the equipment such as mobile phone.Two ends of small diameter coaxial cable bunch 20 carry out the end by mounted connector 25 and form processing, thereby easily are connected with substrate 11,12.In addition, small diameter coaxial cable bunch 20 utilizes braiding sleeve 23 that many small diameter coaxial cables 24 harnesses are formed except two end 21a, 21b, is connected with two substrates with whole U word shape (or J word shape).Thus, can make small diameter coaxial cable bunch 20 substrate 11,12 overlook and become U word shape shape on direction, carry out distribution between two substrates 11,12.In addition, Fig. 1 be small diameter coaxial cable bunch 20 two end 21a, 21b away from state, Fig. 2 is two immediate states of end 21a, 21b.Substrate 11,12 move horizontally distance, be for example 30mm to 60mm left and right.
Small diameter coaxial cable 24, with the diametric(al) section of orthogonality of center shaft on, therefrom the mind-set outside has center conductor, internal insulator, external conductor, crust successively.Implement end and process on the end of small diameter coaxial cable 24 21a, 21b, make external conductor, internal insulator and center conductor in accordance with regulations length expose by different level.In addition, in small diameter coaxial cable bunch 20, except many small diameter coaxial cables, can also comprise does not have the thin footpath of external conductor insulated cable.In addition, for convenience of explanation, reduce the radical of small diameter coaxial cable 24 in accompanying drawing and illustrate.
Small diameter coaxial cable bunch 20 is observed from vertical view, to Width (directions of two arrow W of Fig. 1 (the A)) bending of substrate.Because substrate 11,12 width are for number cm, so can fully guarantee the radius of curvature that the party makes progress.For example as shown in Fig. 1 (A), if an end 21a of small diameter coaxial cable bunch 20 is with respect to glide direction, be connected with it on the right side of upper substrate 11 (upside in Fig. 1 (A)), another end 21b with respect to glide direction, is connected with it in the left side of infrabasal plate 12 (downside in Fig. 1 (A)).Small diameter coaxial cable bunch 20 is bent to U word shape, but for the space of accommodating small diameter coaxial cable bunch 20 is diminished, the width of U word (straight line portion interval) is more narrow better.
In the situation that the existing FPC (flexible printed circuit substrate) that used, because FPC is between two substrates 11,12, with the direction of the in-plane quadrature of substrate on crooked, so in order to ensure its radius of curvature, need to enlarge substrate 11, the gap of 12.In the present invention, two substrates 11, the gap of 12 degree that reaches the thickness of small diameter coaxial cable bunch 20 gets final product.Therefore, do not need as the situation of using FPC greatlyr, can realize the slimming of equipment.
As small diameter coaxial cable 24, preferably use AWG 42, AWG 44, AWG 46 in AWG (American WireGauge) standard for example, or use than above-mentioned thinner Ultrathin coaxial cable, or use the external diameter coaxial cable thinner than 0.30mm.Thus, small diameter coaxial cable bunch 20 is easily crooked, the resistance in the time of can reducing two substrates 11,12 and slide.In addition, by many small diameter coaxial cables of harness 24 when forming small diameter coaxial cable bunch 20, the thickness H1 (with reference to scheming (3)) of small diameter coaxial cable bunch 20 can be formed thinlyyer, can realize the slimming of equipment.Because can also be by with its flattening, carrying out flattening by substrate 11,12 clamping small diameter coaxial cable bunch 20, thus substrate 11,12 the gap can also than the thickness of small diameter coaxial cable bunch 20 slightly (0.2mm left and right) little.As previously mentioned, in small diameter coaxial cable bunch 20, can comprise does not have the thin footpath of external conductor insulated cable, but this thin footpath insulated cable preferably uses the external diameter cable thinner than 0.30mm.
Small diameter coaxial cable bunch 20 comprises 40 to the small diameter coaxial cable 24 of 50 left and right.If the Usage profile diameter is less than or equal to 2.5mm, braiding thickness is less than or equal to the braiding sleeve of 0.2mm, can 40 cables to the radical of 50 left and right of harness.In the situation that small diameter coaxial cable 24 is the fineness that is less than or equal to 0.27mm for the fineness of AWG 46 or external diameter, if approach the bundle of the shape of circle with section, form small diameter coaxial cable bunch 20 (also can comprise thin footpath insulated cable), comprise the thickness that weaves sleeve 23 and be less than or equal to 1.5mm at interior external diameter (thickness), can carry out distribution in the receiving space of the height (thickness) of 1.5mm.If this small diameter coaxial cable bunch 20 is configured to U word shape, the width of this U word can be in 10mm to 16mm.Because of the increase of core number (radical of small diameter coaxial cable 24), the width of U word also can broaden, even but the small diameter coaxial cable 24 of 60 AWG 44 of harness, the width that also can guarantee this U word is in 18mm.
As shown in Figure 1 to Figure 3, small diameter coaxial cable bunch 20 is by penetrating many small diameter coaxial cables 24 in braiding sleeve 23, thus harness and forming.For example as shown in Fig. 3 (C), small diameter coaxial cable bunch 20 is preferably set to, the as far as possible little shape of gauge H1 as flat oval-shaped profile.Weave sleeve 23 by utilization and coat many small diameter coaxial cables 24, improve small diameter coaxial cable bunch 20 for substrate 11, the durability of friction when the walls such as 12 slide.In addition, small diameter coaxial cable bunch 20, due to the area of section sum of the area of section (also comprising inner space) that makes braiding sleeve 23 greater than small diameter coaxial cable, and than loose ground harness small diameter coaxial cable, therefore small diameter coaxial cable 24 easily changes arrangement etc. in braiding sleeve 23, easily moves.
Move horizontally even be connected with respectively the substrate 11,12 at the two ends of small diameter coaxial cable bunch 20, therewith together small diameter coaxial cable bunch 20 by the part repeated deformation of harness, many small diameter coaxial cables 24 also can move in braiding sleeve 23.Therefore, easily avoid on the whole the bending load that applies on small diameter coaxial cable 24, can exceedingly not apply load to small diameter coaxial cable 24.Therefore, even small diameter coaxial cable bunch 20 repeated deformations also can prevent the fracture of the center conductor of small diameter coaxial cable 24.
The braiding sleeve 23 of present embodiment weaves and forms tubular polymer fiber.As polymer fiber, the preferred monofilament composite fibre that is consisted of by melting liquid-crystalline polymer and bendability polymer of using.This monofilament composite fibre is made of core composition and sheath composition, and wherein, this core composition is made of the melting liquid-crystalline polymer, and this sheath composition comprises the bendability polymer.
The melting liquid-crystalline polymer that uses in the core composition, be in fused solution crystallinity (melting anisotropy), namely show the polymer of optical liquid crystal (anisotropy) in melting mutually, the melting liquid crystalline polyester that can use aromatic diol, aromatic dicarboxylic acid, aromatic hydroxy-carboxylic etc. to be consisted of by repetitive structure unit.The fused solution crystallinity can be by for example being placed in high-temperature stage with test portion, and assert through light of test portion observed in the heating that heats up under nitrogen atmosphere.The fusing point of preferred molten liquid crystalline polyester (MP) is 260～360 ℃, more preferably 270～350 ℃.Here said fusing point is by differential scanning heat (DSC: mettler company system for example, the peak temperature of the main endothermic peak of TA3000) observing out (JIS K7121).
In the melting liquid-crystalline polymer, also can add polyethylene terephthalate, sex change polyethylene terephthalate, polyolefin, Merlon, polyarylate, polyamide, polyphenylene sulfide, polyether ester ketone and fluorine-type resin thermoplastic polymer.In addition, also can comprise the various additives such as colouring agent, antioxidant, ultra-violet absorber, light stabilizer such as the inorganic matters such as titanium oxide, kaolin, silicon dioxide, barium monoxide, carbon black, dye well pigment.
The bendability thermoplastic polymer that uses in the sheath composition (bendability polymer) is not particularly limited, and can enumerate polyolefin, polyamide, polyester, polyarylate, Merlon, polyphenylene sulfide, polyester ether ketone and fluorine-type resin etc.Particularly preferably polyphenylene sulfide (PPS), Polyethylene Naphthalate and semi-aromatic polyester acid amides.In addition, said so-called bendability polymer, refer to not have on master lock the polymer of aromatic rings here, and have on master lock on master lock between aromatic rings and aromatic rings and exist more than or equal to four bond things.
For the sheath composition, not only can be consisted of by the bendability thermoplastic polymer, also preferred mixture by bendability thermoplastic polymer and melting liquid crystalline polyester consists of.Particularly preferably form island structure, that is, with the bendability thermoplastic polymer as sea component, with the melting liquid crystalline polyester as island component.By consisting of the sheath composition with the mixture (particularly island structure) that is consisted of by melting liquid crystalline polyester and bendability macromolecule, can improve the intensity of sheath composition, significantly improve simultaneously the cementability between sheath composition and core composition.
Here so-called island structure refers to exist dozens of to the state on hundreds of island in becoming the sea component of matrix in the fiber cross section.Mixing ratio by changing sea component and island component, melt viscosity etc. can be adjusted island quantity.Island structure can mix by sea component and island component are carried out taper, or utilizes static mixer (static mixer) etc. that the fused mass of two compositions is mixed and obtains.Island component ratio in the sheath composition, the Sectional Area of the sheath type composite fibre that produces than (island component/sea component+island component) in, from intensity and anti-fubril this point, be preferably set to 0.25～0.5.Island component is than can try to achieve from the microphotograph in fiber cross section, and the volume ratio of core composition that can also be when making and the spray volume of sheath composition is obtained.The diameter of island component is preferably set to about 0.1～2 μ m.
The melting liquid crystalline polyester of sheath composition can use the melting liquid crystalline polyester identical with the core composition, and they can be identical type, can be also variety classeses.Preferably be less than or equal to the fusing point (MP)+80 ℃ of the bendability thermoplastic polymer of sheath composition, more than or equal to the polymer of MP-10 ℃.In addition, can also comprise other polymer and various additive in the sheath composition.
Consist of the monofilament composite fibre of braiding sleeve 23, except the core-sheath-type composite fibre, also comprise eccentric core-sheath-type.Core composition ratio in composite fibre is set as 0.25～0.80, is preferably set to 0.4～0.7.Particularly, in the situation that consist of the sheath composition by bendability thermoplastic polymer and melting liquid crystalline polyester, the sheath composition also can improve intensity.Therefore, even in the situation that reduction core component ratio also can obtain intensity more than or equal to the high-quality composite fibre of 15g/d.If the core composition is than excessive, core easily exposes, if too small, from the angle of intensity, not enough situation can occur.In addition, said core composition ratio, represent that the area of section of composite fibre is than (core composition/(core composition+sheath composition)) here.The area of section is than trying to achieve from the microphotograph in fiber cross section.The fiber wire diameter rate of change that draws is-3.5～+ 3.5%, more preferably-3.0～+ 3.0%, and preferred saturation (guiding wearing and tearing number of times) is set as more than or equal to 1200 times.
Above-mentioned monofilament composite fibre is woven as shown in Figure 4 and form the braiding sleeve 23.For example, the form of braiding is, prepares the bundle 23a that 16 units form side by side by single fiber (in Fig. 4, the position that is surrounded by circular mark), uses 16 ingots to inweave with tubular.If restraint 23a with 6 to 13 as one, weave with 16 ingots, weave sleeve 23 and roughly consisted of by 100 to 200 single fibers.For example, in the situation that restraint 23a with 9 as one, the quantity of single fiber is 9 * 16=144 root.In addition, the diameter of a single fiber is 0.02mm to 0.10mm, and the thickness (wall thickness of barrel shape) of braiding sleeve 23 is 0.05mm to 0.20mm.In the situation that fibre diameter (bare wire diameter) is 0.045mm, the thickness of braiding sleeve 23 is the 0.1mm left and right.In addition, make braiding sleeve 23 be less than or equal to 2.5mm for the profile diameter under state cylindraceous.When fiber is inweaved, if Usage profile is oval illusory core, or use many sections arranged side by side to be the illusory core of circle, around it, fiber is inweaved, can produce section and be oval braiding sleeve.
The concrete numerical value of the structure of braiding sleeve 23 has been shown in following table 1.Be in the single fiber of 0.045mm at the bare wire diameter, use the melting liquid-crystalline polymer of PET class in the core composition, in the situation that use the bendability thermoplastic polymer of PEN class in the sheath composition, can be counted by holding in following table 1, compile number and spacing, make the braiding sleeve of internal diameter size in following table 1., hold the radical of bare wire that number refers to consist of the bare wire bundle of a single fiber here, compile the quantity that number refers to consist of the bare wire bundle of braiding.In addition, spacing refers to the interval that same twisted wire occurs on the length direction of braiding sleeve.In addition, the size of the bare wire diameter of single fiber, general in the size of possessive construction A～D, be 0.045mm, under the state that flattens extracting heart yearn, the thickness of braiding sleeve 23 is the 0.17mm left and right.

| Structure A | 6 | 16 | 9.6mm | 0.9mm |
| Structure B | 8 | 16 | 12.0mm | 1.2mm |

Resistance to wear, intensity and the modulus of elasticity of the braiding sleeve 23 of said structure are good, use the bendability of small diameter coaxial cable bunch 20 of this braiding sleeve 23 good, and not can because of and substrate 11,12 etc. or and the housing of electronic equipment between repeatedly the friction surperficial roughening that causes weaving sleeve 23 fluff, destroy braiding.Therefore, even small diameter coaxial cable 24 alternating bendings also can prevent center conductor fracture, state that simultaneously can many small diameter coaxial cables of long term maintenance harness 24.
For example, small diameter coaxial cable 24 by bonding band (テ Off ロ Application (registered trade mark) band) 40 AWG 46 rugosity of harness, put in the situation that height slides for the gap of 2.4mm, by repeatedly carrying out 80,000 bendings and slip, can produce the fracture of center conductor, but in the situation that carry out harness by the braiding sleeve 23 of present embodiment, even after repeatedly carrying out 200,000 bendings and slip, can not cause the center conductor fracture yet.
If by constraint small diameter coaxial cables 24 such as bonding bands and carry out harness, this part section shape is difficult to flatten (being difficult to flattening), but weave sleeve 23 harness small diameter coaxial cables 24 by use, many small diameter coaxial cables 24 and braiding sleeve 23 are moved in section simultaneously, make the part of harness and receiving space appropriate flat accordingly.For example, be 2.5mm even make the diameter of braiding sleeve 23 when cylindric, also can by carrying out flattening with space corresponding ground, be less than or equal the thickness (minor axis of flat ellipse) of 1.5mm.Also can use the braiding sleeve of above-mentioned section flat pattern.At the small diameter coaxial cable 24 of preparing 40 AWG46 rugosity, braiding sleeve 23 by present embodiment carries out harness, put into highly as going forward side by side in the situation of line slip in the gap of 1.5mm, even repeatedly carry out 200,000 bendings and slip rear center conductor can not rupture yet.On the other hand, in the situation that carry out harness by bonding band, because diameter is 1.8mm, can't put into the gap of 1.5mm.
In order to make small diameter coaxial cable bunch 20, as shown in Fig. 5 (A), shorter small diameter coaxial cable 24a in the many small diameter coaxial cables 24 that length is different is disposed at central authorities, and configure successively long small diameter coaxial cable 24b towards the end, end 21a, 21b are arranged equally spacedly.And, utilize film or fixture etc. to keep this ordered state on one side, on one side from the end of small diameter coaxial cable 24, center conductor, internal insulator, external conductor are exposed by different level, carry out end and process, further connect connector 25 and carry out the end and form and process.And, by enlarging an end diameter of described braiding sleeve 23, connector 25 is penetrated wherein.Braiding sleeve 23 can with the hole enlargement of for example 2mm diameter to diameter 6mm, pass can make connector mounted many small diameter coaxial cables 24.Thus, as shown in Fig. 5 (B), can form the small diameter coaxial cable bunch 20 that mid portion is formed by braiding sleeve 23 harnesses.In addition, because small diameter coaxial cable 24a that will be shorter is disposed at central authorities, the small diameter coaxial cable 24b that will grow is disposed at the end, therefore when crooked small diameter coaxial cable bunch 20, when being difficult to apply bending or the tension force when reversing, can prevent the fracture of center conductor.
In the fixed situation of the bending direction of small diameter coaxial cable bunch 20, if in the small diameter coaxial cable 24 of equidistantly arranging, a shorter small diameter coaxial cable 24a of side configuration in orientation, form bunch of cables at the long small diameter coaxial cable 24b of opposite side configuration, and make shorter small diameter coaxial cable 24a be configured in curved interior, can effectively reduce the whole load that is caused by bending.
In said embodiment, the situation of carrying out end formation processing for connector 25 is arranged on end 21a, the 21b of small diameter coaxial cable bunch 20 is illustrated, but also can be as Figure 6 and Figure 7, the small diameter coaxial cable 24 of small diameter coaxial cable bunch 20 is directly installed on substrate 11,12 and carries out the end and form and process.In the situation that small diameter coaxial cable 24 is directly installed on substrate 11,12, as long as it is temporary fixed to utilize film etc. that the end of small diameter coaxial cable arranged side by side 24 is carried out with respect to substrate 11,12, center conductor and the substrate 11 of the end of small diameter coaxial cable 24,12 splicing ear are connected by solder get final product.In addition, by earth rod 26 is connected on external conductor, and configure another earth rod 27 or welded part 27 from its opposition side, each small diameter coaxial cable 24 of clamping, thus can constant spacing.Can also at substrate 11,12 single face, (with reference to Fig. 7 (A)) be installed directly, in the situation that substrate 11,12 end are directly installed, (with reference to Fig. 7 (B)) can also be installed directly on the two sides.With above substrate 11 be arranged on its lower surface when being connected, with below substrate 12 surface mounted thereto when being connected.Be not limited to direct installation, also can be when utilizing connector etc. to be connected with substrate 11,12 be connected with substrate 11,12 two sides.
In addition, also can replace the connector 25 of above stated specification, the end of small diameter coaxial cable bunch 20 is connected on FPC (Flexible Printed Circuits), FPC is arranged on substrate 11,12.
In small diameter coaxial cable bunch of the present invention, can make does not have the insulated electric conductor of external conductor suitably to sneak into.Insulated electric conductor can be used as ground wire, or insulated electric conductor is used as supply lines.
In addition, small diameter coaxial cable bunch 20 can also be for the distribution in the equipment beyond the housing that slides.For example as shown in Figure 8, can also pack into and use in the equipment such as mobile phone in relative rotation between housing.And, can also be used for connect relative position and not have situation between vicissitudinous substrate.
In the example of Fig. 8, be formed with straight-line groove 32a and curved groove 32b on the housing 32 of non-moving side.The pin 31a, the 31b intercalation that are arranged on the housing 31 of mobile side enter in above-mentioned groove 32a, 32b.From state shown in Fig. 8 (A), housing 31 is followed the movement of pin 31a and displacement upward, follow simultaneously the movement of pin 31b to counterclockwise rotating, after state through Fig. 8 (B), housing 31 is followed the movement of pin 31a and displacement downwards, follow simultaneously the movement of pin 31b further to counterclockwise rotating, become the state of Fig. 8 (C).Thus, housing 31 is with respect to housing 32 90-degree rotations.At this moment, the small diameter coaxial cable bunch 20 that is connected with substrate that the substrate of housing 31 is connected with housing, with end 21b that housing 32 is connected near be failure to actuate, and the end 21a that is connected with housing 31 carries out displacement up and down, rotates simultaneously 90 degree.By repeatedly carrying out from action and the action opposite with it of Fig. 8 (A) to (C), in small diameter coaxial cable bunch 20, near the part meeting alternating bending 21a of end, and slide in housing 31,32, small diameter coaxial cable 24 moves in the mode of avoiding being applied in load in braiding sleeve 23, prevents the center conductor fracture.If braiding sleeve 23 is to be formed by the monofilament composite fibre braiding that melting liquid-crystalline polymer and bendability polymer consist of, can also prevent the damage that is caused by friction.
Consideration when small diameter coaxial cable 24 being penetrated its inboard, can because enlarging the mesh that is woven, make braiding unclamp from end portion due to described braiding sleeve 23.If braiding is unclamped, workability is bad, also needs to carry out locking operation, and therefore in processing, required time can lengthen, and causes manufacturing cost to increase.Therefore, preferably at the two ends of braiding sleeve 23, undertaken integrated by thermal welding between the polymer fiber that braiding is formed in advance.
The thermal welding of polymer fiber can be crimped on the end portion of braiding sleeve 23 by taper that will heating, makes the melt surface of polymer fiber and makes between polymer fiber welding mutually and carry out.At this moment, if polymer fiber is made of core composition and sheath composition as shown in aforementioned, as long as the Temperature Setting that will make welding between polymer fiber is for higher than the fusing point of sheath composition and lower than the fusing point of core composition, only make the sheath composition because of the heat melts welding, residual because the core composition does not melt, therefore the part of welding can have sufficient intensity, can not disconnect or unclamp.The fusing point of the melting liquid-crystalline polymer that uses in the core composition be as previously mentioned 260～360 ℃, and the fusing point of the bendability thermoplastic polymer that uses is 190～290 ℃ in the sheath composition.For example, if the fusing point of the melting liquid-crystalline polymer of core composition is 340 ℃, the fusing point of the bendability thermoplastic polymer of sheath composition is 270 ℃, as long as the heating-up temperature when setting thermal welding is 290 ℃, will make sheath become fractional melting and the core composition does not melt, therefore can keep weaving the intensity at the both ends (weld portion) of sleeve 23 after welding.
For small diameter coaxial cable being penetrated in the above-mentioned braiding sleeve that makes the two ends thermal welding, as shown in Figure 9, enlarge end 28 from the welding of braiding sleeve 23 a little near the mesh of central part, small diameter coaxial cable 24 is penetrated this opening portion.At this moment, because end 28 is integrated by thermal welding between polymer fiber, therefore can not unclamp.Can before mounted connector, many small diameter coaxial cables 24 be penetrated in this braiding sleeve 23, then connector is connected to from the end of the small diameter coaxial cable 24 of braiding sleeve 23 extensions.Perhaps, after can and carrying out end formation processing in the end that connector is arranged on many small diameter coaxial cables 24, connector and small diameter coaxial cable 24 are penetrated in braiding sleeve 23.Adopt any method, as long as judge according to the size and shape of connector.
Below, utilize Figure 10～14 explanation the second execution modes.
In Figure 10, for 10,11,12,20,21a, 21b, 23,24,25, mark the label identical with Fig. 1.In Figure 10, basic structure is identical with the first execution mode shown in Figure 1.
In Figure 10, small diameter coaxial cable bunch 20 is made of a plurality of wiring harnesses that many small diameter coaxial cables 24 harnesses except both ends 21a, 21b are formed (bundle section of branch) 41,42, and the mode of (or J word shape) is connected with two substrates 11,12 take integral body as U word shape.
As shown in figure 11, the mid portion of above-mentioned small diameter coaxial cable bunch 20 as previously mentioned, by many small diameter coaxial cables 24 being divided into many group (in present embodiment being 2 groups) electric wire groups, by braiding sleeve 23, each electric wire of 23 ' harness group, be wiring harness 41,42 thereby be separated into 2 group of branches bundle sections.The braiding sleeve 23 of present embodiment also with the first execution mode similarly, polymer fiber is woven and forms tubular.In addition, the radical of the small diameter coaxial cable 24 of cutting apart must not be decile, but preferred at least to cut apart more than or equal to the unit of 10.In Figure 11, braiding sleeve 23,23 ' coats small diameter coaxial cable 24 on the almost total length of bundle section of whole branch (wiring harness 41,42), but can be also so that the part of bundle section of branch can be not at random degree the form that formed by the sleeve harness.In this case, the mode that preferably each sleeve is not staggered with length direction is fixed in each bundle section of branch by bonding band etc.
2 groups of wiring harnesses 41,42 when being bent into U word shape being connected with substrate 11,12, are compared with the length of the wiring harness 41 that is disposed at this U word inboard, and the length of wiring harness 42 that is disposed at the U word outside is longer.Thus, when small diameter coaxial cable bunch 20 is configured to linearity, be formed with the remaining length 42a of section on longer wiring harness 42.
In addition, different according to the radius of curvature of cable, the difference in size of wiring harness 41,42 length is different, in the situation that the rate of curving is larger, the difference in size of length is also larger, and in the less situation of the rate of curving, the difference in size of length is also less.
Small diameter coaxial cable bunch of the present invention has the whole small diameter coaxial cable harnesses that will wherein comprise and is the integral body bundle section of.In example shown in Figure 11, be divided on the part of wiring harness 41,42 initiating terminal and terminal of two, the tie part 33 that utilizes sleeve or band that whole small diameter coaxial cables 24 are tied up as a bundle becomes whole bundle section.Utilize this tie part 33, make braiding sleeve 23,23 ' end together fixing with small diameter coaxial cable 24, carry out wiring harness 41,42 end is located.If tie part 33 and make whole small diameter coaxial cables 24 be arranged on connector first-class end of carrying out to form in absence about processing, its end portion namely become whole bundle section.
With the first execution mode similarly, when forming many small diameter coaxial cables of harness 24 and have 2 groups of wiring harnesses 41,42 small diameter coaxial cable bunch 20, each wiring harness 41 of small diameter coaxial cable bunch 20,42 thickness h 1 (with reference to Figure 12 (C)) can be formed thinlyyer, can realize the slimming of equipment.As this thickness h 1, for example preferred heights is less than or equal to 2mm in the present embodiment.Because can by with the wiring harness 41 of small diameter coaxial cable bunch 20,42 by substrate 11,12 and housing clamp to flatten and carry out flattening, so the height in the gap between substrate 11,12 and housing, can be than the thickness of small diameter coaxial cable bunch 20 little 0.2～0.5mm left and right.
In the present embodiment, each wiring harness 41,42 of small diameter coaxial cable bunch 20 comprises the small diameter coaxial cable 24 more than or equal to 10.If the profile diameter of wiring harness is less than or equal to 2.5mm, can insert highly in the gap of 2mm by flattening.As long as the thickness of sleeve is the 0.2mm left and right, be included in small diameter coaxial cable 24 in each wiring harness 41,42 for harness, intensity and durability are all abundant.in the situation that small diameter coaxial cable 24 is the fineness that is less than or equal to 0.27mm for the fineness of AWG 46 or external diameter, as the bundle of section near toroidal, if form the wiring harness 41 of small diameter coaxial cable bunch 20, 42 (also can comprise thin footpath insulated cable), be set as 20 if will be contained in the radical of each intrafascicular small diameter coaxial cable, comprise sleeve 23, 23 ' thickness is less than or equal to 1.5mm at interior external diameter (thickness), be set as 30 if will be contained in the radical of each intrafascicular small diameter coaxial cable, the thickness that comprises sleeve 23 is less than or equal to 1.7mm at interior external diameter (thickness), above-mentioned any situation all can be carried out distribution in the receiving space of 2.0mm height (thickness).If this small diameter coaxial cable bunch 20 is configured to U word shape, the width of this U word can be got in 10mm to 16mm.According to the increase of core number (radical of small diameter coaxial cable 24), the width of U word also can broaden, even but cut apart the small diameter coaxial cable 24 of 60 AWG 44 and carry out harness, the width of this U word also can be in 18mm.
As extremely shown in Figure 12 in Figure 10, small diameter coaxial cable bunch 20 carries out harness by many small diameter coaxial cables 24 are penetrated in sleeve 23,23 ', and become wiring harness 41,42, for example as shown in Figure 12 (C), preferably adopt to make the as far as possible little shape of gauge h1 as flat oval-shaped profile.With the first execution mode similarly, in the present embodiment, also by utilizing sleeve 23,23 ' to coat many small diameter coaxial cables 24, improve the durability of small diameter coaxial cable bunch 20.In addition, due to than loose ground harness small diameter coaxial cable, so small diameter coaxial cable 24 easily moves by change arrangement etc. in sleeve 23,23 '.
The sleeve 23 of present embodiment, 23 ' weaves and forms tubular polymer fiber.Polymer fiber is identical with the first execution mode.
For the small diameter coaxial cable bunch 20 of making present embodiment, many small diameter coaxial cables 24 are divided into 2 groups of electric wire groups, the many small diameter coaxial cables 24 that consist of the said wires group are inserted respectively in sleeve 23,23 ', draw small diameter coaxial cable 24 from sleeve 23,23 ' two ends.In the length of restrainting simultaneously, many small diameter coaxial cables 24 are not divided into 2 groups of electric wire groups (other is identical) by its each length.
In addition, so that be divided into the mode that the part that becomes initiating terminal and terminal in the wiring harness 41,42 of two becomes a bundle, on initiating terminal part and terminal part, other sleeve or coiling band etc. are installed, are formed tie part 33.
Then, utilize film and fixture etc. to keep the ordered state of small diameter coaxial cable 24 on one side, on one side the end from small diameter coaxial cable 24 exposes by different level center conductor and external conductor and carries out end and process, and then connects connector 25 and carry out the end and form and process.
Thus, can form mid portion and be split into 2 groups and have by sleeve 23,23 ' harness and form the wiring harness 41 of (length different), 42 small diameter coaxial cable bunch 20.
In addition, near the part position of carrying out form processing the end, the ordered state of small diameter coaxial cable 24 is maintained plane, can also utilizes band to form tie part 33 plane.
In addition, even the wiring harness 41 of this small diameter coaxial cable bunch 20,42 repeated deformations (crooked or rotation), also can move each other by make many small diameter coaxial cables 24 in sleeve 23,23 ', easily avoid the bending load that applies to small diameter coaxial cable 24, be difficult to apply excessive loads on small diameter coaxial cable 24.Therefore, even small diameter coaxial cable bunch 20 repeated deformations, also the utmost point is difficult to the fracture of generative center conductor.
And, because many small diameter coaxial cables 24 are divided into a plurality of Shu Ercheng of tying in, so can make sleeve 23 in each wiring harness 41,42,23 ' diameter less.Thus, even also can not hinder relatively moving between housing in narrower receiving space, and can not cause the damage of bunch of cables.In addition, by making each wiring harness 41,42 flat the accommodating of sleeve 23, also can be contained in well in highly lower receiving space.
And in the situation that use in the moving part with rotation, torsion, slip etc., different and the wiring harness 41 that will be shorter of the length by making bundle section of branch is configured agley as inboard, can alleviate the stress that the difference by radius of curvature causes.Its result can make the movable range of the bending of small diameter coaxial cable 24 or distortion become large, makes each wiring harness 41,42 follow well moving part and removable, can reduce the generation of the broken string of small diameter coaxial cable 24, improves the reliability of equipment.
In Figure 13, show in the mobile phone that housing rotates, the small diameter coaxial cable bunch 20 of present embodiment is carried out the example of distribution.Housing 31,32 basic structure are identical with the first execution mode (Fig. 8).In the present embodiment, compare with Figure 13 (A), Figure 13 (C), the distance during state of Figure 13 (B) between connector is longer, and small diameter coaxial cable bunch 20 carries out distribution to have remaining long mode, so that its each wiring harness 41,42 longer than the connector spacing of free position.Therefore, even housing slides, small diameter coaxial cable 24 can excessively not stretch yet, and can move in the mode of avoiding being applied in load in sleeve 23,23 ', prevents the center conductor fracture.
Small diameter coaxial cable bunch 50 shown in Figure 14, the many small diameter coaxial cables 24 that length is different, be divided into 2 groups of electric wire groups by its each length, will consist of said wires group's many small diameter coaxial cables 24, carry out harness by sleeve 23,23 ' respectively and be wiring harness 41,42 as bundle section of branch.In this small diameter coaxial cable bunch 50, be connected with respectively connector 51,52 in each wiring harness 41, an end separately of 42.
Thus, in this small diameter coaxial cable bunch 50, wiring harness 41 that will be shorter is as inboard, with U word shape or J word sigmoid and be configured, concentrate the connector 25 that is formed by connecting to be connected with a substrate 11 each wiring harness 41,42, the connector 51,52 that will be connected respectively with each wiring harness 41,42 end is connected respectively independently with another substrate 12.Also have following situation, connector 25 is connected with same substrate and connector 52 is connected with another substrate with being connected, and perhaps connector 25 is connected with same substrate and connector 51 is connected with another substrate with being connected.
When having three substrates, also there is the situation that each connector 25,51,52 is connected with different substrate respectively.In this case, as long as any two in three relatively move.For example, the substrate B that is connected with the substrate A of connector 25 and is connected with connector 51 can not relatively move owing to being contained in same housing, but is connected with between the substrate C of connector 52 and substrate A owing to being contained in situation about relatively moving in different housings etc.
In order to make above-mentioned small diameter coaxial cable bunch 50, many small diameter coaxial cables 24 with different length, be divided into 2 groups of electric wire groups by its each length, the many small diameter coaxial cables 24 that consist of the said wires group are inserted respectively in sleeve 23,23 ', draw small diameter coaxial cable 24 from the two ends of sleeve 23.
In addition, form tie part 33 by at one end side installing sleeve or coiling band etc. so that be divided into two wiring harness 41,42 one distolaterally become a bundle.
Then, by with wiring harness 41,42 one distolateral, gather and carry out end and process and connect connector 25, with wiring harness 41,42 another is distolateral, carry out respectively end and process and connect connector 51,52, form and process thereby implement the end.In this embodiment, can also be with connector 25,51,52 with after small diameter coaxial cable be connected, connector 51,52 is penetrated respectively sleeve 23,23 ' and small diameter coaxial cable is penetrated in sleeve.Tie part 33 can also form before passing sleeve 23,23 '.
As the variation of the small diameter coaxial cable bunch of the execution mode of Figure 14, can also use is becoming the sleeve of two bursts of shapes of a pipe with sleeve 23 and 23 ' near tie part 33 places.
Thus, can form and be split into two strands and have the different wiring harness 41 of the length of utilizing sleeve 23 harnesses to form, 42 small diameter coaxial cable bunch 50.
In addition, in the situation of this small diameter coaxial cable bunch 50, also with described situation similarly, the fracture of center conductor is given birth in utmost point difficult labour, can be contained in well in highly lower receiving space, can make each wiring harness 41,42 follow well moving part and removable.
In addition, in the above-described embodiment, be by many small diameter coaxial cables 24 being divided into 2 groups of electric wire groups, by sleeve 23, each electric wire of 23 ' harness group, separate 2 groups of wiring harnesses 41,42, be not limited to 2 groups but cut apart quantity, can also be more than or equal to 3 groups.
