Description

本発明は、シールド導電体に関する。   The present invention relates to a shield conductor.

特許文献１には、複数本のノンシールド電線を、電線保護機能を有する金属製のシールドパイプに挿通することで、一括してシールドするシールド導電体が開示されている。このようなシールド導電体の使用形態としては、電気自動車の動力回路として車体の床下に沿って配索することができるが、この場合、床下に設けられている機器等との干渉を避けようとすると、配索経路が屈曲した経路となるため、それに合わせてシールドパイプは曲げ加工される。

JP 2004-171952 A

上記のようなシールド導電体は、ハーネスメーカーの工場で製造された後に、自動車メーカーの組み立て工場へ搬送されるのであるが、搬送時には、シールド導電体同士が干渉することによって変形するのを回避するために、１つのシールド導電体毎に直方形の搬送空間が確保される。
ところが、シールド導電路が三次元的に屈曲した細長い形状であって、搬送空間はも長さ方向、幅方向及び高さ方向の全てにおいて大きな寸法を有するため、搬送空間のうちシールド導電体が占める容積は僅かであり、搬送空間の大部分はデッドスペースとなる。
本発明は上記のような事情に基づいて完成されたものであって、搬送時におけるスペース効率の向上を図ることを目的とする。 The shield conductor as described above is manufactured at the harness manufacturer's factory and then transported to the automobile manufacturer's assembly factory. During the transport, the shield conductor avoids deformation due to interference between the shield conductors. Therefore, a rectangular transport space is secured for each shield conductor.
However, the shield conductive path has an elongated shape that is bent three-dimensionally, and the transport space also has large dimensions in all of the length direction, the width direction, and the height direction, and therefore the shield conductor occupies the transport space. The volume is small, and most of the transfer space becomes a dead space.
The present invention has been completed based on the above circumstances, and an object thereof is to improve the space efficiency during transportation.

上記の目的を達成するための手段として、請求項１の発明は、電線を金属製のシールドパイプで包囲したものであって、前記シールドパイプには、筒状を保ちつつ軸線の曲率を増減するように塑性変形させることが可能な変形可能部が設けられているところに特徴を有する。   As means for achieving the above object, the invention of claim 1 is one in which an electric wire is surrounded by a shield pipe made of metal, and the curvature of the axis line is increased or decreased in the shield pipe while maintaining a cylindrical shape. Thus, it is characterized in that a deformable portion that can be plastically deformed is provided.

請求項２の発明は、請求項１に記載のものにおいて、前記変形可能部は、軸線方向に沿って径が交互に増減する形態の波形に形成されているところに特徴を有する。   A second aspect of the invention is characterized in that, in the first aspect of the invention, the deformable portion is formed in a waveform having a shape in which the diameter is alternately increased or decreased along the axial direction.

請求項３の発明は、請求項２に記載のものにおいて、前記変形可能部が、外周及び内周に螺旋形のネジ山が形成された形態とされているところに特徴を有する。   A third aspect of the invention is characterized in that, in the second aspect of the invention, the deformable portion is formed in a spiral thread formed on the outer periphery and the inner periphery.

請求項４の発明は、請求項１ないし請求項３のいずれかに記載のものにおいて、前記変形可能部が、前記シールドパイプと一体に形成されているところに特徴を有する。   The invention of claim 4 is characterized in that, in the invention of any one of claims 1 to 3, the deformable part is formed integrally with the shield pipe.

＜請求項１の発明＞
シールド導電体を搬送する際には、シールド導電体を包囲する直方形の寸法が小さくなるように変形可能部を変形させれば、搬送空間中のデッドスペースを小さくすることができる。また、搬送後は、変形可能部を変形させることにより、シールド導電体を所定の配索経路に沿った形状にすればよく、シールド導電体は、変形可能部の剛性によって所定の配索路経路に保たれる。 <Invention of Claim 1>
When the shield conductor is transported, the dead space in the transport space can be reduced by deforming the deformable portion so that the rectangular dimensions surrounding the shield conductor are reduced. In addition, after the conveyance, the deformable portion may be deformed to form the shield conductor along a predetermined routing path. The shield conductor is determined according to the rigidity of the deformable portion. To be kept.

＜請求項２及び請求項３の発明＞
変形可能部を変形させるときには、一方の波形のピッチが狭まるように変形するのに伴って、それとは反対側の波形のピッチが広がるように変形するので、シールドパイプの肉厚が極端に変化することがない。したがって、曲げ可能部が曲げ変形によって破壊する虞はない。 <Invention of Claim 2 and Claim 3>
When the deformable part is deformed, the thickness of the shield pipe changes extremely as the pitch of the waveform on the opposite side increases as the pitch of the waveform on one side decreases. There is nothing. Therefore, there is no possibility that the bendable portion is broken due to bending deformation.

＜請求項４の発明＞
変形可能部がシールドパイプと一体に形成されているので、別体部品として成形した変形可能部をシールドパイプに固着するものに比べて、部品数が少なくて済む。 <Invention of Claim 4>
Since the deformable part is formed integrally with the shield pipe, the number of parts can be reduced as compared with the case where the deformable part formed as a separate part is fixed to the shield pipe.

＜実施形態１＞
以下、本発明を具体化した実施形態１を図１〜図７を参照して説明する。本実施形態のシールド導電体Ａは、一括シールド機能と電線保護機能を兼ね備えるシールドパイプ１０と、複数本（本実施形態では３本）のノンシールドタイプの電線２０とを備えて構成されている。
シールドパイプ１０は、アルミニウム合金製であり、その長さ方向（軸線方向）と直角な横断面形状は真円形をなしている。
電線２０は、アルミニウム合金製の単芯線や銅製の撚り線等からなる導体（図示せず）の外周を合成樹脂製の絶縁被覆で包囲した周知の形態のものであり、導体と絶縁被覆はいずれも可撓性を有しているので、電線２０は自在に曲げ変形することができる。複数本の電線２０はシールドパイプ１０内に挿通され、このシールドパイプ１０で包囲されることにより一括してシールドされている。尚、電線２０の両端部はシールドパイプ１０の両端の開口から外部へ所定長さだけ導出されている。 <Embodiment 1>
A first embodiment of the present invention will be described below with reference to FIGS. The shield conductor A of the present embodiment includes a shield pipe 10 having both a collective shield function and an electric wire protection function, and a plurality of (three in the present embodiment) non-shield type electric wires 20.
The shield pipe 10 is made of an aluminum alloy, and the cross-sectional shape perpendicular to the length direction (axial direction) is a perfect circle.
The electric wire 20 has a well-known form in which the outer periphery of a conductor (not shown) made of a single core wire made of aluminum alloy, a copper stranded wire, or the like is surrounded by an insulating coating made of synthetic resin. Is also flexible, the electric wire 20 can be freely bent and deformed. The plurality of electric wires 20 are inserted into the shield pipe 10 and are collectively shielded by being surrounded by the shield pipe 10. Note that both ends of the electric wire 20 are led out by a predetermined length from the openings at both ends of the shield pipe 10 to the outside.

シールド導電体Ａは、電気自動車の車体の床下（図示せず）に沿うように取り付けられ、その配索経路は、床下に設けられている各種機器との干渉を回避するために屈曲した形態とされ、シールドパイプ１０は、７つの直線部１１ａ〜１１ｇを６つの屈曲部１２ａ〜１２ｆで直列状に連結した形態となっている（図１、図３及び図４を参照）。   The shield conductor A is attached along the floor (not shown) of the body of the electric vehicle, and the routing route is bent to avoid interference with various devices provided under the floor. The shield pipe 10 has a configuration in which seven straight portions 11a to 11g are connected in series with six bent portions 12a to 12f (see FIGS. 1, 3 and 4).

シールドパイプ１０の前端部である第１直線部１１ａは、その端部を上向きに開口させるようにほぼ垂直に配索されている。第１直線部１１ａの下端部の第１屈曲部１２ａからは、第２直線部１１ｂが第１直線部１１ａに対して略直角をなすように水平右方へ延出されている。第２直線部１１ｂの右端（延出端）の第２屈曲部１２ｂからは、第３直線部１１ｃが、第２直線部１１ｂに対して略直角をなすように水平後方へ延出されている。第３直線部１１ｃの後端（延出端）の第３屈曲部１２ｃからは、第２直線部１１ｂとほぼ同じ長さの第４直線部１１ｄが、第３直線部１１ｃに対して略直角をなすように水平左方へ延出されている。第４直線部１１ｄの左端（延出端）の第４屈曲部１２ｄからは、第５直線部１１ｅが、第４直線部１１ｄに対して直角に近い鈍角をなすように水平に且つ斜め後左方へ延出されている。第５直線部１１ｅの後端の第５屈曲部１２ｅからは、第６直線部１１ｆが、第５直線部１１ｅに対してほぼ直線に近い鈍角をなすように水平に且つ斜め右後方へ延出されている。第６直線部１１ｆの後端の第６屈曲部１２ｆからは、第１直線部１１ａよりも長い（高い）第７直線部１１ｇが、第６直線部１１ｆに対して略直角をなすように垂直方向上向きに延出されている。   The first straight portion 11a, which is the front end portion of the shield pipe 10, is arranged substantially vertically so as to open the end portion upward. From the 1st bending part 12a of the lower end part of the 1st linear part 11a, the 2nd linear part 11b is extended to the horizontal right side so that it may make a substantially right angle with respect to the 1st linear part 11a. From the second bent part 12b at the right end (extended end) of the second straight part 11b, the third straight part 11c extends horizontally rearward so as to be substantially perpendicular to the second straight part 11b. . From the third bent portion 12c at the rear end (extended end) of the third straight portion 11c, a fourth straight portion 11d having substantially the same length as the second straight portion 11b is substantially perpendicular to the third straight portion 11c. It extends horizontally to the left. From the fourth bent portion 12d at the left end (extending end) of the fourth straight portion 11d, the fifth straight portion 11e is horizontally and diagonally rear left so as to form an obtuse angle close to a right angle with respect to the fourth straight portion 11d. It is extended towards. From the fifth bent portion 12e at the rear end of the fifth straight portion 11e, the sixth straight portion 11f extends horizontally and diagonally right rearward so as to form an obtuse angle close to a straight line with respect to the fifth straight portion 11e. Has been. From the sixth bent portion 12f at the rear end of the sixth straight portion 11f, a seventh straight portion 11g that is longer (higher) than the first straight portion 11a is perpendicular to the sixth straight portion 11f. The direction is extended upwards.

第１屈曲部１２ａと第４屈曲部１２ｄと第６屈曲部１２ｆは、本発明の変形可能部に相当する。即ち、この３つの屈曲部１２ａ，１２ｄ，１２ｆは、シールドパイプ１０とほぼ同径の筒状を保ちつつ軸線の曲率を増減するように塑性変形させることが可能となっている。この塑性変形は作業者が手作業によって行うことが可能となっている。そして、このような塑性変形を可能とするために、各屈曲部１２ａ，１２ｄ，１２ｆは、シールドパイプ１０の外周と内周に一定ピッチで螺旋状のネジ山及び溝が形成されるように加工され、これにより、軸線方向に沿って径が交互に増減する形態の波形に形成されている（図７を参照）。
尚、第２屈曲部１２ｂと第３屈曲部１２ｃと第５屈曲部１２ｅは、直線部１１ａ〜１１ｇと同様、軸線方向において径寸法が一定のままであるため、容易に変形させることができないようになっている。 The first bent portion 12a, the fourth bent portion 12d, and the sixth bent portion 12f correspond to the deformable portion of the present invention. That is, the three bent portions 12a, 12d, and 12f can be plastically deformed so as to increase or decrease the curvature of the axis while maintaining a cylindrical shape having substantially the same diameter as the shield pipe 10. This plastic deformation can be performed manually by an operator. In order to enable such plastic deformation, the bent portions 12a, 12d, and 12f are processed so that spiral threads and grooves are formed at a constant pitch on the outer periphery and inner periphery of the shield pipe 10. Thus, a waveform is formed in such a form that the diameter alternately increases and decreases along the axial direction (see FIG. 7).
Note that the second bent portion 12b, the third bent portion 12c, and the fifth bent portion 12e, like the straight portions 11a to 11g, have the same diameter in the axial direction, and thus cannot be easily deformed. It has become.

かかるシールド導電体Ａを所定の配索経路（図１、図３及び図４を参照）のままで搬送するために直方形状の搬送空間を確保しようとした場合、搬送空間は、前後方向においては、図５に想像線で示すように第１屈曲部１２ａ（変形可能部）から第６屈曲部１２ｆ（変形可能部）に至る寸法Ｌｘが必要であり、左右方向（幅方向）においては、図５に想像線で示すよう第５屈曲部１２ｅから第３直線部１１ｃ（第２屈曲部１２ｂ及び第３屈曲部１２ｃ）に至る寸法Ｗｘ（第２直線部１１ｂ及び第４直線部１１ｄよりも長い寸法）が必要であり、上下方向においては、図６に想像線で示すように、第７直線部１１ｇの高さに相当する寸法Ｈｘが必要であるため、大容積となる。ところが、シールド導電体Ａ自体は、細長いシールドパイプ１０を屈曲させた形態であるため、この搬送空間内の大部分はデッドスペースが占めることになる。   In order to secure a rectangular transport space in order to transport the shield conductor A in a predetermined routing route (see FIGS. 1, 3 and 4), the transport space is 5, a dimension Lx from the first bent portion 12a (deformable portion) to the sixth bent portion 12f (deformable portion) is required as shown by an imaginary line in the left-right direction (width direction). As shown by an imaginary line in FIG. 5, a dimension Wx (second linear portion 11b and fourth linear portion 11d) extending from the fifth bent portion 12e to the third straight portion 11c (second bent portion 12b and third bent portion 12c) is longer. In the vertical direction, as shown by an imaginary line in FIG. 6, a dimension Hx corresponding to the height of the seventh straight portion 11g is necessary, and the volume is large. However, since the shield conductor A itself has a shape in which the elongated shield pipe 10 is bent, the dead space occupies most of the transport space.

そこで、本実施形態では、上記のように第１屈曲部１２ａと第４屈曲部１２ｄと第６屈曲部１２ｆを塑性変形可能としたことにより、搬送空間の容積を小さくすることができるようにしている。
即ち、搬送する際には、図５に実線で示すように、第４屈曲部１２ｄを変形させつつ（第４屈曲部１２ｄを略支点として）第５直線部１１ｅを第３直線部１１ｃと平行をなすように水平面上で右方へ旋回させるように変位させる。この第５直線部１１ｅの水平変位に伴い、第６直線部１１ｆと第７直線部１１ｇが、第５直線部１１ｅと一体となって右方へ水平移動するとともに、第６屈曲部１２ｆが、左右方向において第３直線部１１ｃ（第２屈曲部１２ｂ及び第３屈曲部１２ｃ）とほぼ同じ位置に達する。これにより、図５に実線で示すように、シールド導電体Ａの左右寸法Ｗｙは、第２直線部１１ｂ及び第４直線部１１ｄの長さとほぼ同じ寸法となり、搬送空間として必要な左右方向の寸法が、変形前の寸法Ｗｘに比べて小さく抑えられる。 Therefore, in the present embodiment, the first bent portion 12a, the fourth bent portion 12d, and the sixth bent portion 12f can be plastically deformed as described above, so that the volume of the conveyance space can be reduced. Yes.
That is, when transporting, as shown by the solid line in FIG. 5, the fifth straight portion 11e is parallel to the third straight portion 11c while the fourth bent portion 12d is deformed (with the fourth bent portion 12d as a substantially fulcrum). So as to make a right turn on the horizontal plane. Along with the horizontal displacement of the fifth straight portion 11e, the sixth straight portion 11f and the seventh straight portion 11g move horizontally to the right together with the fifth straight portion 11e, and the sixth bent portion 12f It reaches substantially the same position as the third straight portion 11c (the second bent portion 12b and the third bent portion 12c) in the left-right direction. Thereby, as shown by a solid line in FIG. 5, the left-right dimension Wy of the shield conductor A is substantially the same as the lengths of the second straight part 11b and the fourth straight part 11d, and the horizontal dimension required for the conveyance space. However, it is suppressed to be smaller than the dimension Wx before the deformation.

また、第４屈曲部１２ｄを支点として水平変位させたことにより、第６屈曲部１２ｆ及び第７直線部１１ｇが、変形前に比べて前方に位置する状態となる。これにより、図５に実線で示すように、シールド導電体Ａの前後寸法Ｌｙが小さくなり、搬送空間として必要な前後方向の寸法が小さく抑えられる。   In addition, the sixth bent portion 12f and the seventh linear portion 11g are positioned forward compared to before the deformation by horizontally displacing the fourth bent portion 12d as a fulcrum. As a result, as shown by a solid line in FIG. 5, the front-rear dimension Ly of the shield conductor A is reduced, and the front-rear dimension required for the conveyance space is kept small.

さらに、第１屈曲部１２ａを変形させつつ（第１屈曲部１２ａを略支点として）第１直線部１１ａを後方へ直角に倒して第３直線部１１ｃと平行をなすように水平姿勢にするとともに、第６屈曲部１２ｆを変形させつつ（第６屈曲部１２ｆを略支点として）第７直線部１１ｇを前方へ直角に倒して第３直線部１１ｃ及び第５直線部１１ｅと平行をなすように水平姿勢にする。これにより、図６に実線で示すように、シールド導電体Ａの上下寸法Ｈｙが変形前よりも小さくなり、搬送空間として必要な上下方向（高さ方向）の寸法が小さく抑えられる。この搬送空間の高さ寸法Ｈｙは、シールドパイプ１０の外径と同じかそれよりも少し大きい寸法である。   Further, while deforming the first bent portion 12a (using the first bent portion 12a as a substantially fulcrum), the first straight portion 11a is tilted rearward at a right angle so as to be parallel to the third straight portion 11c. Then, while deforming the sixth bent portion 12f (with the sixth bent portion 12f as a substantially fulcrum), the seventh straight portion 11g is tilted forward at a right angle so as to be parallel to the third straight portion 11c and the fifth straight portion 11e. Set to horizontal position. Thereby, as shown by a solid line in FIG. 6, the vertical dimension Hy of the shield conductor A becomes smaller than that before the deformation, and the vertical dimension (height direction) necessary for the conveyance space is kept small. The height Hy of the transfer space is the same as or slightly larger than the outer diameter of the shield pipe 10.

上述のように本実施形態においては、シールドパイプ１０に、筒状を保ちつつ軸線の曲率を増減するように塑性変形させることが可能な変形可能部（第１屈曲部１２ａ、第４屈曲部１２ｄ、第６屈曲部１２ｆ）を設けたので、シールド導電体Ａを搬送する際には、シールド導電体Ａを包囲する直方形の寸法が小さくなるように変形可能部を変形させることにより、搬送空間中のデッドスペースを小さくすることができる。
また、搬送後は、変形可能部（第１屈曲部１２ａ、第４屈曲部１２ｄ、第６屈曲部１２ｆ）を元の向き及び元の曲率に復元するように変形させ、シールド導電体Ａを所定の配索経路に沿った形状にすればよい。復元後は、シールド導電体Ａは、変形可能部（第１屈曲部１２ａ、第４屈曲部１２ｄ、第６屈曲部１２ｆ）の剛性によって所定の配索路経路に保たれる。
尚、シールド導電体Ａの製造時に、変形可能部（第１屈曲部１２ａ、第４屈曲部１２ｄ及び第６屈曲部１２ｆ）は、直線状のままにしておき、その状態から搬送に好適な配索形状に曲げ変形させてもよい。 As described above, in the present embodiment, the deformable portions (first bent portion 12a and fourth bent portion 12d) that can be plastically deformed so as to increase or decrease the curvature of the axis while maintaining the cylindrical shape in the shield pipe 10. Since the sixth bent portion 12f) is provided, when the shield conductor A is transported, the deformable portion is deformed so that the dimension of the rectangular shape surrounding the shield conductor A is reduced, thereby transporting space. The inside dead space can be reduced.
Further, after the conveyance, the deformable portions (the first bent portion 12a, the fourth bent portion 12d, and the sixth bent portion 12f) are deformed so as to restore the original direction and the original curvature, and the shield conductor A is predetermined. What is necessary is just to make it the shape along the routing route. After restoration, the shield conductor A is maintained in a predetermined routing path by the rigidity of the deformable portions (first bent portion 12a, fourth bent portion 12d, and sixth bent portion 12f).
When the shield conductor A is manufactured, the deformable portions (the first bent portion 12a, the fourth bent portion 12d, and the sixth bent portion 12f) are kept in a straight shape, and the arrangement suitable for transportation from the state is made. It may be bent and deformed into a cord shape.

また、変形可能部（第１屈曲部１２ａ、第４屈曲部１２ｄ及び第６屈曲部１２ｆ）は、軸線方向に沿って径が交互に増減する形態の波形に形成されているので、変形可能部を変形させるときには、一方（曲げの内側）の波形のピッチが狭まるように変形するのに伴って、それとは反対側（曲げの外側）の波形のピッチが広がるように変形することになる。したがって、シールドパイプ１０の肉厚が極端に変化することがなく、変形可能部（第１屈曲部１２ａ、第４屈曲部１２ｄ及び第６屈曲部１２ｆ）が曲げ変形によって破壊する虞はない。
また、変形可能部（第１屈曲部１２ａ、第４屈曲部１２ｄ及び第６屈曲部１２ｆ）が、シールドパイプ１０と一体に形成されているので、別体部品として成形した変形可能部をシールドパイプ１０に固着するものに比べて、部品数が少なくて済んでいる。 In addition, the deformable portions (the first bent portion 12a, the fourth bent portion 12d, and the sixth bent portion 12f) are formed in a waveform having a shape in which the diameter is alternately increased and decreased along the axial direction. Is deformed so that the pitch of the corrugation on the opposite side (outside of the bend) is widened as the pitch of the corrugation on one side (inside of the bend) is narrowed. Therefore, the thickness of the shield pipe 10 does not change extremely, and there is no possibility that the deformable portions (the first bent portion 12a, the fourth bent portion 12d, and the sixth bent portion 12f) are destroyed by bending deformation.
In addition, since the deformable portions (the first bent portion 12a, the fourth bent portion 12d, and the sixth bent portion 12f) are integrally formed with the shield pipe 10, the deformable portion formed as a separate part is used as the shield pipe. Compared to what is fixed to 10, the number of parts is small.
