Cable supporting member and cable supporting arrangement
The present invention relates to a kind of integrated with cable and to the cable supporting arrangement that this cable supports, such as, relate to a kind of to being assembled in the cable supporting member and cable supporting arrangement that the cable that uses in the robot mobile device etc. of machine line, semiconductor-fabricating device, electronic component mounting appts etc. supports.
The robot mobile device carried for holding the workpiece such as workpiece, wafer, substrate is assembled with in machine line, semiconductor-fabricating device, electronic component mounting appts.Robot mobile device move back and forth in orbit mobile trolley used in be mounted with robot for carrying such as workpiece.By making the hand motion of the arm of this robot, hand can be made to hold workpiece and install and remove this workpiece in each processing equipment.
This robot mobile device mobile trolley used on be connected with the pipe etc. (hereinafter referred to as " cable ") of cable, optical cable, oil pressure or air pressure power supply.Because mobile trolley used constantly moving back and forth makes its change in location, therefore, cable need be made to follow the change of this position to move rightly together with mobile trolley used.Therefore, there will be a known the cable supporting member of the joint type being such as called cable shafts (Japanese: ケ mono-Block Le ベ ア) (registered trade mark): by making the cable of certain length bend to U-shaped to carry out the length variations supporting the limit making U-shaped relative, thus make cable follow mobile trolley used change in location.
This cable supporting member that can bend to U-shaped is documented in Japanese Patent Laid No. 4658221 publication.The a series of synthetic resin block that the cable supporting member (multi-joint supporting member) of Japanese Patent Laid No. 4658221 publication is linked by being closed by keying is formed.In addition, in Japanese Patent Laid No. 4658221 publication, cable supporting member is inserted the pliability conveyer belt component that comprises multiple configuration pipeline arranged side by side and is clamped integratedly together with cable, thus forms joint type cable protection guider.In addition, supporting member can be bent to regulation radius of curvature according to the shape of its block, and on the other hand, horizontal linear state overcomes gravity and is maintained or is prevented from decurvation and becomes convex.
The cable supporting member that can bend to U-shaped is also documented in Japanese Patent Laid No. 4157096 publication, in Japanese Patent Laid No. 4157096 publication, cable supporting member by belt there is flexible stainless steel band (flexible material) and injection molded and a series of plastic block member (non-interlock solid shape thing) being fixed on this stainless steel band is formed.In addition, this cable supporting member is inserted multiple disposed chamber arranged side by side and is documented in by the cable supporting structure clamped integratedly in Figure 21 of Japanese Patent Laid No. 4157096 publication etc. together with cable.
A series of synthetic resin clamp dog bodies of the cable supporting member of Japanese Patent Laid No. 4658221 publication also comprise pin for linking and by injection molded fairly simple manufactured, on the other hand, when synthetic resin block is linked, whole pin of many synthetic resin blocks need be made to be fitted together to with its corresponding hole, therefore, also not necessarily think that assembleability is good.In addition, because being used for using pin that space connected to each other for synthetic resin clamp dog body is made the longer dimension on axis direction (length of cable direction), therefore, also there is following technical problem: can not reduce when cable supporting member is bent can obtain minimum profile curvature radius and thus for the expectation space of distribution.
The block member (non-interlock solid shape thing) of the cable supporting member of Japanese Patent Laid No. 4157096 publication is fixed on stainless steel band by injection molded, but when adopting this structure, the part being fixed on the block member of stainless steel band not can be used as spring and effectively works.This is to the disadvantageous main cause of the spring design of stainless steel band, may not obtain enough fatigue strength.In addition, also can think by block member injection molded in the operation of stainless steel band be the main cause that productivity reduces.
In addition, the cable supporting member of Japanese Patent Laid No. 4658221 publication and Japanese Patent Laid No. 4157096 publication can work within the specific limits along a direction, but becomes complete inoperative supporting member because locating part works on the rightabout reverse with this direction.Therefore, when being applied with the load on rightabout to cable supporting member, in the cable supporting member of Japanese Patent Laid No. 4658221 publication, the pin joint portion of synthetic resin block is destroyed, or in the cable supporting member of Japanese Patent Laid No. 4157096 publication, stainless steel band (mobility material) and block member (non-interlock solid shape thing) may be peeled off and destroy.
The present invention does in view of above-mentioned technical problem, the cable supporting member that its first object is to provide a kind of durability higher and cable supporting arrangement.The cable supporting member that second object is to provide a kind of manufacturing good and cable supporting arrangement.
For solving the problems of the technologies described above, the invention provides a kind of cable supporting member, this cable supporting member comprises multiple block member and elastic component, it is characterized in that, above-mentioned block member has the elastic component inserted for above-mentioned elastic component and inserts road, in addition, also there is the articular surface that can carry out under the state that contacts with each other of both sides on the length direction of above-mentioned cable supporting member and adjacent block member rotating, road inserted by the above-mentioned elastic component that multiple above-mentioned block member inserted by above-mentioned elastic component, multiple above-mentioned block member is kept to arrange, and, above-mentioned elastic component applies compression stress to multiple above-mentioned block member, thus the neutral condition of substantially linear and diastrophic case of bending can be obtained on global shape.
Like this, multiple block member of cable supporting member afford compressive load because inserting its elastic component and are kept, but individually do not fix with elastic component, in addition, multiple block member be each other only with articular surface contact but not such as sold each other wait link simple structure, therefore, can obtain and comprise the higher and cable supporting arrangement of cable supporting member that is that easily manufacture of durability.
In addition, also the length in the axis of block member (length of cable direction) can be made to become quite short because of the above-mentioned simple structure of block member, by this, the cable supporting member that minimum profile curvature radius is less can be obtained.
In addition, cable supporting member can adopt following structure: can from above-mentioned neutral condition towards a direction and the rightabout elastic bending deflection contrary with an above-mentioned direction, and when affording certain bending load, make towards above-mentioned rightabout diastrophic deflection less than the diastrophic deflection towards an above-mentioned direction.
Like this, owing to can think that cable supporting member is not flexible compared with a direction, but in the opposite direction also can flexural deformation, therefore, even if when cable supporting member is applied to being difficult on rightabout predict compared with heavy load, also can be out of shape, thus can breakage be prevented.
In the present invention, when being kept in the horizontal direction by cable, cable supporting member can be made to be essentially zero towards the above-mentioned rightabout diastrophic deflection produced because of deadweight.
In the present invention, it is preferable that, when cable supporting member is towards an above-mentioned direction flexural deformation, the multiple block member rotation separately carrying out rotating is orthogonal with elastic component.
In the present invention, the elastic component of supporting member can be made to be made up of cylindrical coil spring.Like this, the higher supporting member of durability can be obtained because of the bending higher elastic deformability on anti-helical spring axis direction.
In the present invention, can obtain when an above-mentioned direction flexural deformation, the Thickness Ratio being positioned at the wall portion of the pipe component of outer circumferential side is positioned at the thick pipe component of the thickness of the wall portion of inner circumferential side.Like this, by thickening the outer circumferential side of pipe component, can improve make when cable supporting arrangement moves because of with such as load its another component contact and cause the vibration of generation and the effect of noise attentuation.
In the present invention, each connecting portion that the multiple cables be arranged are inserted between road and cable is inserted between road and supporting member path of pipe component can disconnect each other with manpower.By this; the cable of the pipe component of side more outer than retaining element can be made to insert road with connecting portion to be separated simply from adjacent inserting road; consequently; even if the position of the connecting object of multiple cable is separated from one another, also multiple cable can be connected to each connecting object under the state protected with pipe component.
In the present invention, pipe component has: two outside wall portions, and these two outside wall portions have relative outer surface; And a wall portion, the shape of cross section of this wall portion is in wave shape, this wall portion is located between two outside wall portions, and two outside wall portions is combined with each top of above-mentioned waveform, and supporting member is inserted road and/or cable and inserted road and can be formed by of a wall portion waveform portion and outside wall portions respectively.
By forming pipe component like this, with there is Long Circle, the pipe component inserting road in ellipse or spindle cross section compares, voidage can be made to reduce and carry out distribution with high density to cable, on the other hand, compare with by the pipe component that road forms of inserting of the lower square-section of such as voidage, the bending stiffness of pipe component can be reduced.
In addition, to achieve these goals, the feature of cable supporting member of the present invention comprises: have multiple block member of through hole in inside, namely have the block member at the junction surface can rotated under the open side of the above-mentioned through hole state that block member above-mentioned with other engages respectively, and be inserted through the above-mentioned through hole of the multiple above-mentioned block member engaged with above-mentioned junction surface and there is the elastic component of flexible linearly shape all the time, under inserting at above-mentioned elastic component the state being fixed on multiple above-mentioned block member, above-mentioned block member is maintained at the state of joint, when the above-mentioned block member of joint being rotated towards a direction and the rightabout contrary with this direction the state being bonded into linearity from above-mentioned block member, the addendum modification then making above-mentioned elastic component overcome active force displacement when rotating towards side, an above-mentioned direction is less than making above-mentioned elastic component overcome the addendum modification of active force displacement when rotating towards above-mentioned rightabout side.
By this, when being applied with load (being set to load facing one direction) from elastic component towards block member to cable supporting member, because multiple block member can towards a direction warpage, therefore, when the elastic component with elasticity (elasticity) be U-shaped bend time, multiple block member follows the bending of elastic component and becomes U-shaped.On the other hand, when being applied with the load from block member towards elastic component the load of the direction towards the opposite (, be namely set to the load identical with load facing one direction) to cable supporting member, because multiple block member can warpage and warpage on warpage force rate direction on rightabout be energetically in the opposite direction, therefore, the elastic component with elasticity (elasticity) bend to than U-shaped more open arciform, multiple block member follows the bending of elastic component and becomes arciform.Thus, can provide a kind of easily bending and not flexible in the opposite direction towards a direction, even if when being applied with the load on rightabout also survivable cable supporting member.
In addition, it is characterized in that, above-mentioned elastic component act on have tensile force state under be fixed on above-mentioned block member.
By this, owing to being in the compressive state of effect between multiple block member, therefore, can improving and prevent the supporting force of cable to prevent the sagging of cable.In addition, it is preferable that, be formed with through hole in the mode rotating shaft of rotating towards a direction at multiple block member junction surface configuring the major axis center of elastic component.

The pipe component 9 of present embodiment has: insert for cable supporting member 1 and insert road 9a at two supporting members that two external side parallel extend; And be arranged and insert between the 9a of road in above-mentioned supporting member and three cables inserted for cable 11 insert road 9b.In the present embodiment, these are inserted road and all have oblong shape of cross section, and are combined with adjacent road of inserting in this oblong end.In addition, by by such as using EPTFE(expanded PTFE) be bonded together as two blocks of sheet materials of mother metal in the mode remaining out the space of inserting road, or using polyvinyl chloride as material to its melting extrusion molding in addition, thus this pipe component 9 can be produced.
In addition, in the embodiment of figure 1, the cross section inserting road of pipe component 9 is Long Circle, but the execution mode that cross section is spindle, ellipse, circle, rectangle etc. also can use in the present invention.
Fig. 2 is the figure of the end side representing cable supporting member 1 of the present invention.This cable supporting member 1 has the length of the length of cable direction extension along the cable 11 that will support, and in addition, comprising: along rectangular-shaped multiple block member 2 of cable length direction arrangement; Be applied in the elastic component 3 be made up of cylindrical coil spring 3 of multiple block member 2 that above-mentioned length of cable direction arranges; Though and illustrate only one of end side in fig. 2, be fixed on two shroud members 4 at the both ends of elastic component 3.Block member 2 is not limited to rectangular-shaped, also can be cylindrical shape etc.In addition, the elastic component 3 running through block member 2 is not limited to one, and the elastic component 3 of more than two also can be adopted to run through the structure of block member 2.
As the material of block member 2, the metal material such as resin material, aluminium, the wood materials etc. such as such as liquid crystal polymer (LCP), polyacetals (POM), polyether-ether-ketone (PEEK), polybutylene terephthalate (PBT) (PBT) can be listed.In addition, in order to improve mar proof, also can glass filler being blended in resin material, in addition, in order to realize low friction, also can mixing polytetrafluoroethylene (PTFE).In addition, in the execution mode of Fig. 2, elastic component 3 is by the thread cylindrical coil spring of stainless steel, but for the distortion on axis direction and flexural deformation, there is stronger elastic deformability because if elastic component 3 has, therefore, elastic component 3 also can be made up of the bar-shaped component of such as rubber.
As shown in Fig. 3 (A), block member 2 is formed the elastic component run through along cable length direction running through installation for elastic component 3 and inserts road (through hole) 2a.The drum that road (through hole) 2a is not limited to hollow inserted by elastic component, as long as elastic component can be made to insert and the shape kept, therefore, both can be the shape of cross section of the C type of such as partly open, also can be square hole etc.In addition, as shown in Fig. 3 (B), the side on the length of cable direction of block member 2 is formed with the first articular surface 2k 1, and be formed with second joint face 2k at opposite side 2.First articular surface 2k 1by the first protuberance 2b of semicircle shape with form with the end face on the length of cable direction of the first recess 2c of this first protuberance 2b continuous print semicircle shape, in addition, second joint face 2k 2by the second recess 2d of semicircle shape with form with the end face on the length of cable direction of the second protuberance 2e of this second recess 2d continuous print semicircle shape.With the first articular surface 2k 1with second joint face 2k 2mode chimeric each other, makes the first protuberance 2b be formed by identical diameter respectively with the second protuberance 2e with the second recess 2d, the first recess 2c.
When multiple block member 2 being arranged along cable length direction, the first protuberance 2b embeds the second recess 2d, and the second protuberance 2e embeds the first recess 2c.In addition, center of arc Cb, Cd of the first protuberance 2b and the second recess 2d are formed as being positioned at when observing with Fig. 3 (B) running through and are installed on elastic component and insert on the central axis L of the elastic component 3 of road (through hole) 2a.In addition, center of arc Ce, Cc of the second protuberance 2e and the first recess 2c are positioned on the straight line La of decentre axis L distance a in the top of Fig. 3 (B).
In addition, be formed relative to through center of arc Cd and with the straight line Lb of central axis L-orthogonal with the rake 2f of angle Cl at the second recess 2d with the formation side opposite side of the second protuberance 2e.On the other hand, the line part 2g relative to the straight line Lc offset distance b through center of arc Cb and with central axis L-orthogonal is formed in the side contrary with the side of formation first recess 2c of the first protuberance 2b.When multiple block member 2 being arranged along cable length direction, between rake 2f and line part 2g, be formed with gap.
In addition, as shown in Fig. 3 (C), the side on the length of cable direction of block member 2 is formed with the protuberance 2h of rectangle, and the opposite side on cable length direction is formed with the recess 2i of rectangle.When multiple block member 2 being arranged along cable length direction, protuberance 2h embeds recess 2i.
The block member 2 of such formation can make its first articular surface 2k 1and second joint face 2k 2with the second joint face 2k of adjacent block member 2 2and the first articular surface 2k 1under the state contacted respectively each other clockwise or rotate counterclockwise.In addition, the first protuberance 2b, the first recess 2c of block member 2, the second recess 2d, the second protuberance 2e, protuberance 2h and recess 2i are configured to the junction surface when multiple block member 2 being rotated when the open side of through hole 2a engages.
As shown in Figure 2, the shroud member 4 of the flange part 4b in cylindrical portion 4a and the large footpath with hollow cylindrical at the end winding support of elastic component 3.In the present embodiment, the end of the elastic component 3 inserted in its cylindrical portion 4a is fixed in shroud member 4 crimping.But also can be shroud member by welding, soldering, pin other fixing means such as to fix and is fixed on the execution mode of elastic component.In addition, shroud member 4 another side unshowned in Fig. 2 contrary with the end side of supporting member 1 is fixed on elastic component 3 similarly.
In addition, cable supporting member 1 is by multiple block member 2 compressive press forces of elastic component 3 to arrangement.Therefore, elastic component 3 is in the extended state from the stretched certain length of its drift under the linear state of Fig. 2, and by the end face of the cylindrical portion 4a of two shroud members 4 being fixed on elastic component 3 two ends to many block member 2 compressive press forces clamped.As shown in Figure 2, the multiple block member 2 being applied compression stress make its articular surface (junction surface) contact with each other and the shape that is arranged in a straight line.
In the embodiment shown in figure 2, the power produced because of the extended state of elastic component 3 acts on block member 2 by shroud member 4, but also can form pin-and-hole 2j(with reference to Fig. 3 in the block member 2 being positioned at cable supporting member 1 two ends), make pin (not shown) through this pin-and-hole 2j, make the block member 2 being positioned at two ends locking with elastic component 3, and by multiple block member 2 compressive press forces that be arranged in inner side of these two block member 2 to other.In addition, pin also can be made to pass the pin-and-hole 2j of the block member 2 of the optional position of cable supporting member 1 to be fixed elastic component 3.
According to the cable supporting member 1 of said structure, when being applied with the load P b from elastic component 3 towards the direction of block member 2 to cable supporting member 1, namely make block member 2 contact with each other towards articular surface (junction surface) as shown in Figure 2 and load (load towards a direction) on direction that the direction of line part 2g, the rake 2f contact of block member 2 that arranges is rotated, cable supporting member 1 is bending towards Bb direction.Now, elastic component 3 is towards the elastic bending of Bb direction, as mainly draw out the U-shaped bend of cable supporting member 1 Fig. 4 shown in, because the first protuberance 2b can rotate in the second recess 2d, therefore, multiple block member 2 is towards a direction warpage, if elastic component 3 bends to U-shaped, then multiple block member 2 follows the bending of elastic component 3 and becomes U-shaped.Now, the rake 2f of U-shaped part and line part 2g abutting or close, the minimum profile curvature radius R of U-shaped part is determined by the angle θ of rake 2f and the length axially of block member 2.In addition, the center of rotation now of block member 2 is consistent with center of arc Cb, Cd of the first protuberance 2b and the second recess 2d.
On the other hand, when load (being set to load in the opposite direction) when being applied with the load P a from block member 2 towards the direction of elastic component 3 to cable supporting member 1, on direction that the direction that namely makes block member 2 be separated towards line part 2g, the rake 2f of the block member 2 of arrangement is as shown in Figure 2 rotated, cable supporting member 1 is bending towards Ba direction.Now, elastic component 3 elastic bending on Ba direction, because the second protuberance 2e can rotate in the first recess 2c, therefore, multiple block member 2 warpage in the opposite direction, if elastic component 3 bend to than U-shaped more open arciform, then multiple block member 2 follows the bending of elastic component 3 and becomes arciform.Now, center of arc Cb, Cd of first protuberance 2b and the second recess 2d are positioned on the central axis L of elastic component 3, center of arc Ce, Cc of second protuberance 2e and the first recess 2c are positioned on the straight line La of decentre axis L distance a, therefore, the warpage power on the direction of the warpage force rate on rightabout is large.By this, the cable supporting member 1 of present embodiment has easy bending towards a direction and not easily bends such character in the opposite direction.In other words, cable supporting member 1 have when bearing certain bending load by the neutral condition of linearity towards above-mentioned rightabout diastrophic deflection than towards the little such character of the deflection in an above-mentioned direction.
This is following cause: due to the center of arc Cb of the first protuberance 2b and the second recess 2d, Cd is positioned on the central axis L of elastic component 3, the center of arc Ce of the second protuberance 2e and the first recess 2c, Cc is positioned on the straight line La of decentre axis L distance a, therefore, even if amount of spin is identical, compared with the situation making block member 2 rotate towards a direction centered by center of arc Cb or Cd, when making block member rotate in the opposite direction centered by center of arc Ce or Cc, the addendum modification of elastic component 3 or span are also larger, consequently, rotation in the opposite direction more needs power.In the present embodiment, center of arc Cb, Cd, namely each rotation that cable supporting member 1 rotates towards the multiple block member 2 during a direction flexural deformation is configured to just in time orthogonal with the central axis L of elastic component 3, but be in the such viewpoint of optimum balance from the bending easness made towards a direction with bending easness in the opposite direction, though with the execution mode that the central axis L of above-mentioned elastic component 3 is non-orthogonal reluctantly but orthogonal with elastic component 3, namely above-mentioned rotation is configured to the execution mode orthogonal with elastic component 3 is also one of ideal execution mode.
In addition, the power (compression stress) central axis L along elastic component 3 worked due to the load that cable supporting member 1 is bending required in the opposite direction with the center of arc Ce being separated above-mentioned distance a, the moment that Cc is relevant has proportionate relationship, therefore, when the cable supporting member 1 that hope bending stiffness is in the opposite direction higher, by increasing above-mentioned distance a, incipient extension amount when increasing such as its assembling to increase the power of elastic component 3 or improve the spring constant of elastic component 3, second protuberance 2e of each block member 2 and the first recess 2c is out of shape (such as, second protuberance 2e and the first recess 2c is all set to straight line.With reference to Fig. 9.) realized.Easily can realize the bending stiffness in the opposite direction improving the cable supporting member 1 obtained like this, until when configuring in the horizontal direction because of the deadweight of cable 11 and cable supporting arrangement 10 and the diastrophic deflection in the opposite direction produced become in fact till zero, if desired, can also improve further.
In addition, because center of arc Cb, Cd of the first protuberance 2b and the second recess 2d are positioned on the central axis L of elastic component 3, therefore, usually, block member 2 can be arranged in a straight line shape keep the elastic component 3 of linearity under the state engaging (the first protuberance 2b and the second recess 2d is fitted together to).
In addition, because the protuberance 2h of multiple block member 2 embeds recess 2i, therefore, even if apply torsion to cable supporting member 1, namely around the revolving force of the central axis L of elastic component 3, also can prevent multiple block member 2 from offseting such situation.
In addition, even if rotate until rake 2f contacts with line part 2g in block member 2, the protuberance 2h of rectangle and the recess 2i of rectangle is also in chimeric state (the protuberance 2h of rectangle is positioned at the state of the recess 2i of rectangle), and under preventing the anglec of rotation of the block member 2 considered in design (block member is rotated until rake 2f situation about contacting with line part 2g), multiple block member 2 offsets such situation.
In addition, due to elastic component 3 act on have tensile force state under be fixed on block member 2, therefore, be between multiple block member 2 effect compressive state, the supporting force of cable can be improved to prevent the sagging of cable.
In addition, because elastic component 3 is not fixed on block member 2, but be inserted through block member 2, block member 2 is compression stress because affording from elastic component 3 and contacts with each other and maintain the structure of arrangement, therefore, even if when being applied with the load on rightabout, block member 2, elastic component 3 also can be prevented damaged.In the present embodiment, under the neutral condition of the linearity of cable supporting member 1, elastic component 3 pairs of block member 2 compressive press forces, but elastic component 3 also to be adopted under the neutral condition of cable supporting member 1 not to the execution mode of block member 2 active force.In this case, under linear state, do not afford power from elastic component 3 with multiple block member 2 that articular surface is chimeric each other, but when such as flexural deformation in the opposite direction, elastic component 3 acts on to multiple block member 2 effectively.
Then, when being described retaining element 5, the retaining element 5 of the first execution mode is located at the both ends of a cable supporting arrangement 10, in FIG, at the retaining element 5 by showing the end on the upside of figure under state fixing for cable 11, on the other hand, under the state be decomposed, show the retaining element 5 of the end on the downside of figure.As shown in Figure 1, retaining element 5 comprises: clip pipe component 9 grade and relative two boards component 6; The supporting member being configured at pipe component 9 to be inserted in the 9a of road and two Detent fittings 7 be clipped between two boards component 6; And eight hold-down screws 8.Board member 6 is metal and in the form of a substantially rectangular, but the long side with rectangle depicts the profile of concave arc, and in addition, board member 6 also has four hole 6a for being fixed on Detent fitting 7; And for being fixed on two device fixing hole 6b of such as robot mobile device (not shown) etc.In addition, board member 6 also has three inwards outstanding kick 6c to reliably hold fixed cable class 11.
Fig. 5 is the enlarged partial isometric view of Fig. 1, and is the amplification stereogram of the end of Detent fitting 7 and the cable supporting member 1 being installed on Detent fitting 7.As shown in Figure 5, Detent fitting 7 has: the stud upright portion 7b being equipped with two stud 7a of band screw hole; And U-shaped part 7c.The cylindrical portion 4a of shroud member 4 is chimeric with the inner space of the U-shaped part 7c of Detent fitting 7, and the flange part 4b of shroud member 4 is configured between the end of U-shaped part 7c and adjacent stud 7a.
Owing to inserting each configuration two ends on the 9a of road at two supporting members in pipe component 9 liang of outsides, the cable supporting member 1 of Detent fitting 7 is installed, and under the state of inserting road 9b at three cables making cable 11 insert pipe component 9, with screw, two boards component 6 is fixed on the stud 7a of Detent fitting 7 from the top of pipe component 9, therefore, cable supporting member 1 and cable 11 can be fixed to one another by the retaining element 5 of such formation under the state being contained in pipe component 9, and can use as cable supporting arrangement 10 one.
Then, the cable supporting arrangement of second embodiment of the invention is described.This cable supporting arrangement is relative to the cable supporting arrangement of the first execution mode, and pipe component 109 is different, but has identical structure in other side, therefore, with reference to sectional elevation and Fig. 6 of this pipe component 109, is described different aspects.
Figure 6 illustrates the cable supporting arrangement of the second execution mode.The variation point of this feature is the wall portion 109c on the upside of figure 1wall thickness t 1formed than the wall portion 109c on the downside of figure 2wall thickness t 2thick.Herein, the outer circumferential side when upside of the pipe component 109 of Fig. 6 corresponds to cable supporting member 1 and makes pipe component 109 bend to U-shaped towards an above-mentioned direction thus, downside corresponds to inner circumferential side.When making cable supporting arrangement bend to U-shaped and move it, the outer circumferential side of pipe component 109 corresponds to the side contacted with another component (not shown) of this cable supporting arrangement of mounting.Therefore, by thickening the outer circumferential side of pipe component 109, can improve when cable supporting arrangement moves because causing the vibration of generation and the attenuating of noise with another member contact above-mentioned.In addition, by making inner circumferential side thinning, can flexibility be guaranteed, and lightweight can be realized simultaneously.
Then, the cable supporting arrangement of third embodiment of the invention is described.This cable supporting arrangement is relative to the cable supporting arrangement of the first execution mode, pipe component 209 is different, but other aspects have identical structure, therefore, with reference to Fig. 7 that namely the enlarged partial cross-sectional view of this pipe component 209 represents centered by two of pipe component 209 fusiform cables insert between the 209b of road connecting portion 209d, only different aspect is described.
In the cable supporting arrangement of the 3rd execution mode, each connecting portion 209d that multiple cables of the configuration arranged side by side of pipe component 209 are inserted between the 209b of road can disconnect each other with manpower.Although not shown, but supporting member to insert road with the cable connecting portion 209d inserted between the 209b of road be also same formation.This connecting portion 209d is formed by upper and lower two surfaces the slit 209s wall thickness of connecting portion 209d being decreased in the present embodiment about 1/2 such degree of depth.In addition, though the thickness being defined as keeping cable 11 can break with manpower by the thickness reduced like this of connecting portion 209d.Also the execution mode that slit 209s is formed by any surface up and down in figure can be adopted.In addition, also can adopt following execution mode: by not arranging slit etc. but making the wall thickness of the wall ratio wall portion 209c of connecting portion 209d entirety thin, can be separated at connecting portion 209d place.
In the cable supporting arrangement of the 3rd execution mode; can make to insert road 209b than the cable of the pipe component 209 of the more outer side of retaining element 5 with connecting portion 209d to be separated simply from adjacent inserting road; consequently; even if the position of the connecting object of multiple cable 11 is separated from one another, also multiple cable 11 can be connected to each connecting object under the state protected with pipe component 209.
Then, with reference to sectional elevation and Fig. 8, the cable supporting arrangement of the 4th execution mode is described.This cable supporting arrangement is relative to the cable supporting arrangement of the first execution mode, and pipe component 309 is different, but other side has identical structure, therefore, is only described different aspects.
The feature of the cable supporting arrangement of the 4th execution mode is different from the first execution mode on this aspect of shape of cross section that it has Fig. 8.Therefore, the pipe component 309 of the 4th execution mode comprises: have outer surface and relative two outside wall portions 309c; And be formed at shape of cross section between above-mentioned two outside wall portions 309c in wave shape between each top of the above-mentioned waveform of wall portion 309e, a wall portion 309e be combined with above-mentioned two outside wall portions 309c.Consequently, supporting member is inserted road 309a and cable and is inserted road 309b and formed by the waveform portion of a wall portion 309e and outside wall portions 309c respectively.
By forming pipe component 309 as the 4th execution mode, with there is Long Circle, the pipe component inserting road in ellipse or spindle cross section compares, voidage can be made to reduce and carry out distribution with high density to cable 11, on the other hand, compare with by the pipe component that road forms of inserting of the lower square-section of such as voidage, the bending stiffness of pipe component can be reduced.
The cable supporting arrangement 10 of the first execution mode comprises two cable supporting members 1, but in the present invention, as other execution mode, also the number of cable supporting member 1 can be adopted to be two or three above execution modes (not shown), the configuration position of cable supporting member 1 also might not be defined in pipe component 9 two outside, and can be various position.Similarly, the cable of pipe component also can be adopted to insert road 9b is not multiple but the execution mode of.
In addition, in the first embodiment, first protuberance 2b of the block member 2 of cable the supporting member 1 and center of arc Cb of the second recess 2d, Cd is positioned on the central axis L of elastic component 3, the center of arc Ce of the second protuberance 2e and the first recess 2c, Cc is positioned on the straight line La of decentre axis L distance a, but in the present invention, also following execution mode can be adopted: the center of arc Cb of the first protuberance 2b and the second recess 2d, Cd is not positioned on the central axis L of elastic component 3, but the center of arc Ce be located at than the second protuberance 2e and the first recess 2c, Cc is closer to the position of above-mentioned central axis L.Even if in this embodiment, cable supporting member also has easy bending towards a direction and not easily bends such character in the opposite direction.
In addition, also following execution mode can be adopted: although adopt in cable supporting member, there is the block member (not shown) that the first protuberance 2b and the second recess 2d does not have the second protuberance 2e and the first recess 2c.In the case of this embodiment, what also can bring cable supporting member is all with the result of center of arc Cb, Cd of the first protuberance 2b of each block member 2 and the second recess 2d rotation that is fulcrum towards a direction and rightabout flexural deformation.
In addition, multiple block member 2 due to cable supporting member 1 have and contact such simple structure with articular surface (junction surface) each other, therefore, the length in the axis (length of cable direction) of block member 2 is much short compared with the length shown in Fig. 3 (B), such as, also can be set to less than 1/2.By shortening the length axially of block member 2 like this, thus the less cable supporting member 1 of minimum profile curvature radius can be obtained.
