Description

本開示は、ワイヤハーネスに関する。 The present disclosure relates to wire harnesses.

従来、例えば車両用のワイヤハーネスにおいては、電線への通電に伴い発生する電磁ノイズを遮蔽するために、シールド部材によって電線が覆われている。シールド部材は、例えば、アルミニウム合金などの導電性の素線が筒状に編み込まれた編組線からなり、可撓性を有している。こうしたシールド部材としては、電線の絶縁被覆の外周をシールド部材で個別に覆う個別シールド部材が知られている（例えば、特許文献１参照）。また、複数の電線を１つのシールド部材で一括して覆う一括シールド部材が知られている（例えば、特許文献２参照）。なお、個別シールド部材や一括シールド部材の端部は、ワイヤハーネスのコネクタに電気的に接続される。そして、コネクタが車両の機器の筐体などに接続されることで個別シールド部材及び一括シールド部材がアース接続される。 2. Description of the Related Art Conventionally, in wire harnesses for vehicles, for example, wires are covered with a shield member in order to shield electromagnetic noise generated as the wires are energized. The shield member is made of, for example, a braided wire in which conductive strands of an aluminum alloy are braided into a tubular shape, and has flexibility. As such a shield member, an individual shield member that individually covers the outer periphery of the insulating coating of the electric wire with a shield member is known (see, for example, Patent Document 1). Also, there is known a collective shield member that collectively covers a plurality of electric wires with one shield member (see, for example, Patent Document 2). The ends of the individual shield members and the collective shield member are electrically connected to connectors of the wire harness. Then, the individual shield member and the collective shield member are grounded by connecting the connector to the housing of the equipment of the vehicle or the like.

ところで、個別シールド部材と一括シールド部材とがワイヤハーネスの長さ方向の異なる位置に設けられる場合、個別シールド部材と一括シールド部材とを電気的に接続する必要がある。 By the way, when the individual shield member and the collective shield member are provided at different positions in the length direction of the wire harness, it is necessary to electrically connect the individual shield member and the collective shield member.

例えば、特許文献３には、個別シールド部材と一括シールド部材とを接続する以下の接続構造が記載されている。すなわち、図５に示すように、一対の電線５１０において、芯線５１１の外周を覆う絶縁被覆５１２の外周に金属製の筒状部材５２０が設けられ、更にその外周が個別シールド部材５３０に覆われている。各個別シールド部材５３０の外周は、相互にまたがるようにして一括シールド部材５４０にて覆われている。そして、一括シールド部材５４０の外周にてバンド部材５５０が締付けられることで、バンド部材５５０と筒状部材５２０との間で各個別シールド部材５３０と一括シールド部材５４０とが圧接し、相互が電気的に接続される接続構造を採っている。 For example, Patent Document 3 describes the following connection structure for connecting an individual shield member and a collective shield member. That is, as shown in FIG. 5, in a pair of electric wires 510, a metal cylindrical member 520 is provided on the outer periphery of an insulating coating 512 that covers the outer periphery of a core wire 511, and the outer periphery is further covered by an individual shield member 530. there is The outer periphery of each individual shield member 530 is covered with a collective shield member 540 so as to straddle each other. By tightening the band member 550 on the outer periphery of the collective shield member 540, the individual shield members 530 and the collective shield member 540 are pressed against each other between the band member 550 and the cylindrical member 520, and the mutual electrical contact is made. It adopts a connection structure that is connected to

しかしながら、上記接続構造では、隣接の電線５１０の個別シールド部材５３０にまたがるように装着される一括シールド部材５４０は、各個別シールド部材５３０同士の対向する側とは反対側の半周部分が接触する部分である。言い換えると、各個別シールド部材５３０同士が対向する残りの半周部分は、一括シールド部材５４０と個別シールド部材５３０とが接触しない隙間５６０となっている。そのため、各個別シールド部材５３０と一括シールド部材５４０との接触範囲が狭く互いの固着力が低いため、個別シールド部材５３０と一括シールド部材５４０との長さ方向における位置ずれが生じるおそれがある。 However, in the above-described connection structure, the collective shield member 540 mounted so as to straddle the individual shield members 530 of the adjacent electric wires 510 is the portion where the semicircular portions of the individual shield members 530 on the side opposite to the opposing sides contact each other. is. In other words, the remaining semicircular portion where the individual shield members 530 face each other forms a gap 560 where the collective shield member 540 and the individual shield members 530 do not contact each other. Therefore, since the contact range between each individual shield member 530 and the collective shield member 540 is narrow and the fixing force between them is low, there is a possibility that the individual shield members 530 and the collective shield member 540 are misaligned in the longitudinal direction.

そこで、個別シールド部材と一括シールド部材との位置ずれの発生を抑制することができるワイヤハーネスを提供することを目的とする。 Accordingly, it is an object of the present invention to provide a wire harness capable of suppressing occurrence of positional deviation between an individual shield member and a collective shield member.

本開示のワイヤハーネスは、複数の電線と、導電性の素線が筒状に編み込まれた編組線からなり、複数の前記電線を個別に覆うことで電磁シールドする複数の個別シールド部材と、導電性の素線が筒状に編み込まれた編組線からなり、複数の前記電線を一括して覆うことで電磁シールドする筒状の一括シールド部材と、前記個別シールド部材と前記一括シールド部材とを重ねた状態で電気的に接続する接続部材と、を備え、前記接続部材は、前記一括シールド部材における前記個別シールド部材との重なる部分の外周に設けられ、互いに隣り合う前記電線同士の間に向かって突出する突出部を有するワイヤハーネスである。 The wire harness of the present disclosure includes a plurality of electric wires and a braided wire in which conductive wires are woven into a cylindrical shape, and a plurality of individual shield members that individually cover the plurality of electric wires to electromagnetically shield, A cylindrical collective shielding member made of a braided wire in which individual wires are woven into a cylindrical shape, and collectively covering a plurality of the electric wires for electromagnetic shielding, and the individual shielding member and the collective shielding member are overlapped. and a connection member for electrically connecting the electric wires in a state in which the electric wires are adjacent to each other. A wire harness having a protruding protrusion.

最初に本開示の実施形態を列記して説明する。
本開示のワイヤハーネスは、
［１］複数の電線と、導電性の素線が筒状に編み込まれた編組線からなり、複数の前記電線を個別に覆うことで電磁シールドする複数の個別シールド部材と、導電性の素線が筒状に編み込まれた編組線からなり、複数の前記電線を一括して覆うことで電磁シールドする筒状の一括シールド部材と、前記個別シールド部材と前記一括シールド部材とを重ねた状態で電気的に接続する接続部材と、を備え、前記接続部材は、前記一括シールド部材における前記個別シールド部材と重なる部分の外周に設けられ、互いに隣り合う前記電線同士の間に向かって突出する突出部を有するワイヤハーネスである。 [Description of Embodiments of the Present Disclosure]
First, the embodiments of the present disclosure will be listed and described.
The wire harness of the present disclosure includes:
[1] A plurality of individual shielding members that are composed of a plurality of electric wires and a braided wire in which conductive wires are woven into a cylindrical shape, and that individually cover the plurality of electric wires for electromagnetic shielding, and the conductive wires is composed of a braided wire that is woven into a tubular shape, and a tubular collective shield member that electromagnetically shields by collectively covering a plurality of the electric wires, and a state in which the individual shield member and the collective shield member are superimposed on each other. and a connecting member for connecting the wires, wherein the connecting member is provided on the outer circumference of a portion of the collective shield member that overlaps the individual shield member, and has a projecting portion that projects toward between the adjacent electric wires. wire harness.

各電線の個別シールド部材にまたがって装着される一括シールド部材を含め、接続部材はその一部が互いに隣り合う電線同士の間に向かって押し込まれる突出部を有する。すなわち、隣接の電線の個別シールド部材同士の間に生じる隙間に接続部材の突出部が存在するため、各個別シールド部材それぞれに一括シールド部材が回り込んで半周を超えるような範囲まで接触範囲を広くすることが可能となる。また、接続部材のかしめ等の締付け時に電線及び個別シールド部材が隙間側に変形して逃げることも抑制でき、締付け力の低下も抑制できる。よって、個別シールド部材と一括シールド部材との固着力を強くすることができ、個別シールド部材と一括シールド部材との位置ずれの発生を抑制することが可能となる。 The connecting members, including the collective shielding member that straddles the individual shielding members of each wire, have protrusions that are partially pushed between adjacent wires. In other words, since there is a projecting portion of the connection member in the gap between the individual shield members of the adjacent electric wires, the collective shield member wraps around each individual shield member to widen the contact range to a range exceeding half the circumference. It becomes possible to In addition, it is possible to prevent the electric wire and the individual shield member from deforming and escaping toward the gap when the connection member is crimped or otherwise tightened, and reduction in the tightening force can also be suppressed. Therefore, the fixing force between the individual shield member and the collective shield member can be strengthened, and it is possible to suppress the occurrence of positional deviation between the individual shield member and the collective shield member.

［２］前記突出部は、第１突出部と第２突出部とを有し、前記第１突出部と前記第２突出部とは、複数の前記電線の並び方向と直交する方向に対向していると良い。一括シールド部材は、互いに対向する第１突出部と第２突出部との両側から押し込まれる。すなわち、隣接の電線の個別シールド部材同士の間に生じる隙間それぞれに接続部材の第１突出部と第２突出部とが存在するため、各個別シールド部材それぞれと一括シールド部材との接触範囲を十分広くすることが可能となる。また、接続部材のかしめ等の締付け時に電線及び個別シールド部材が隙間側に変形して逃げることも各突出部にて抑制でき、締付け力の低下もより確実に抑制できる。よって、個別シールド部材と一括シールド部材との固着力をより強いものとすることができるからである。 [2] The projecting portion has a first projecting portion and a second projecting portion, and the first projecting portion and the second projecting portion face each other in a direction perpendicular to the direction in which the plurality of electric wires are arranged. It's good to be The collective shield member is pushed in from both sides of the first projecting portion and the second projecting portion that face each other. That is, since the first projecting portion and the second projecting portion of the connecting member are present in the respective gaps between the individual shielding members of the adjacent electric wires, the contact range between each individual shielding member and the collective shielding member is sufficiently large. It is possible to widen it. In addition, each projecting portion can prevent the electric wire and the individual shield member from deforming and escaping toward the gap when the connection member is crimped or otherwise tightened. Therefore, the fixing force between the individual shield member and the collective shield member can be made stronger.

［３］前記第１突出部と前記第２突出部との各対向面は、複数の前記電線の並び方向と平行な平面をなしていると良い。第１突出部と第２突出部とが一括シールド部材をそれぞれ押し込む互いの対向面が複数の電線の並び方向と平行な平面、すなわちその押し込み方向と直交する平面となっている。このため、第１突出部と第２突出部とが一括シールド部材を押し込む際、一括シールド部材の損傷を抑制することができるからである。 [3] It is preferable that each opposing surface of the first projecting portion and the second projecting portion forms a plane parallel to the direction in which the plurality of electric wires are arranged. Mutual opposing surfaces into which the first projecting portion and the second projecting portion push the collective shield member are planes parallel to the direction in which the plurality of wires are arranged, that is, planes orthogonal to the pushing direction. Therefore, when the first projecting portion and the second projecting portion push the collective shield member, damage to the collective shield member can be suppressed.

［４］前記第１突出部と前記第２突出部との各対向面は、その間に対をなして介在する前記一括シールド部材の部位同士が接触しない間隔で離隔していると良い。第１対向面と第２対向面との間に対をなして介在する一括シールド部材の部位同士に互いに適度なスペースが得られ、一括シールド部材の損傷を抑制することができるからである。 [4] It is preferable that the facing surfaces of the first projecting portion and the second projecting portion are spaced apart from each other by a distance that does not allow the portions of the collective shield member interposed in pairs therebetween to come into contact with each other. This is because a proper space can be obtained between portions of the collective shield member interposed in pairs between the first opposing surface and the second opposing surface, and damage to the collective shield member can be suppressed.

［５］前記接続部材は、前記個別シールド部材の各々に対応する複数の多角形筒状部を有し、複数の前記電線の並び方向に沿って複数の前記多角形筒状部が前記突出部を介して連接された形状であると良い。接続部材の多角形筒状部にて一括シールド部材と各個別シールド部材とのかしめ等による締付けが行われると、電線及び個別シールド部材、更には一括シールド部材が円筒状から多角形筒状に倣った若干の変形を伴うため、部分的に相互間の圧接力を高めることができる。よって、個別シールド部材と一括シールド部材との固着力を高めることができるからである。 [5] The connection member has a plurality of polygonal tubular portions corresponding to each of the individual shield members, and the plurality of polygonal tubular portions extends along the direction in which the plurality of wires are arranged. It is preferable that the shape is connected via the . When the collective shield member and each individual shield member are tightened by caulking or the like at the polygonal tubular portion of the connecting member, the electric wires, the individual shield members, and the collective shield member follow the polygonal tubular shape from the cylindrical shape. Since it is accompanied by slight deformation, it is possible to partially increase the pressure contact force between them. Therefore, it is possible to increase the fixing force between the individual shield member and the collective shield member.

［６］複数の前記電線に個別に挿通させるための複数の筒状部材を備え、前記筒状部材は、前記接続部材を設ける位置の前記電線と前記個別シールド部材との間に介在されていると良い。筒状部材により電線を保護できることに加え、一括シールド部材を含めた接続部材によるかしめ等の締付けを筒状部材を土台にして行えることで、個別シールド部材と一括シールド部材との固着力を高めることができるからである。 [6] A plurality of tubular members for individually inserting the plurality of wires are provided, and the tubular members are interposed between the wires and the individual shield members at positions where the connection members are provided. and good. In addition to being able to protect the electric wire by the cylindrical member, the fixing force between the individual shield member and the collective shield member can be increased by using the cylindrical member as a base for tightening such as caulking by the connection member including the collective shield member. This is because

Each cylindrical member 50 is provided at a portion of each electric wire 10 where the individual shield member 31 is covered with the collective shield member 32 . That is, each cylindrical member 50 is provided at a position corresponding to the connection portion 32 c of the collective shield member 32 in the length direction of the electric wire 10 . The individual shield member 31 has a folded portion 31c at a position corresponding to the connecting portion 32c. Cylindrical member 50 is interposed between electric wire 10 and individual shield member 31 so as to be wrapped by folded portion 31c. The tubular member 50 is preferably made of a rigid metal material, such as brass.

＜接続部材６０＞
図２～図４に示すように、ワイヤハーネス１には、各個別シールド部材３１と一括シールド部材３２とを重ねた状態で電気的に接続する接続部材６０が設けられている。接続部材６０は、一括シールド部材３２のうち個別シールド部材３１の各々を覆う部分の外周に設けられている。すなわち、接続部材６０は、一括シールド部材３２の接続部３２ｃの外周面を全周にわたって覆っている。接続部材６０は、剛性を有する金属材料であることが好ましく、例えばアルミニウムの板材が板金加工されることによって形成されている。接続部材６０は、個別シールド部材３１の各々に対応する複数の多角形筒状部（例えば、六角形筒状部６１）を有し、複数の電線１０の並び方向に沿って２つの六角形筒状部６１が一対の突出部６２を介して連接された中空形状である。 <Connecting member 60>
As shown in FIGS. 2 to 4, the wire harness 1 is provided with a connecting member 60 that electrically connects the individual shield members 31 and the collective shield member 32 while they are superimposed. The connection member 60 is provided on the outer circumference of the portion of the collective shield member 32 that covers each of the individual shield members 31 . That is, the connection member 60 covers the entire outer peripheral surface of the connection portion 32c of the collective shield member 32. As shown in FIG. The connection member 60 is preferably made of a metal material having rigidity, and is formed, for example, by sheet metal processing an aluminum plate material. The connection member 60 has a plurality of polygonal tubular portions (for example, hexagonal tubular portions 61) corresponding to each of the individual shield members 31, and has two hexagonal tubular portions along the direction in which the plurality of electric wires 10 are arranged. It has a hollow shape in which the shaped portion 61 is connected via a pair of protruding portions 62 .

各突出部６２は、互いに隣り合う電線１０同士の間に向かって突出している。一対の突出部６２は、第１突出部６３と、複数の電線１０の並び方向と直交する方向において第１突出部６３と対向する第２突出部６４と、を有している。第１突出部６３は、複数の電線１０の並び方向と平行な平面の第１対向面６３ａを有している。第２突出部６４は、複数の電線１０の並び方向と平行な平面の第２対向面６４ａを有している。第１突出部６３と第２突出部６４との各対向面６３ａ、６４ａは、その間に対をなして介在する一括シールド部材３２の部位同士が接触しない間隔Ｌにて離隔している。 Each protruding portion 62 protrudes toward between the electric wires 10 adjacent to each other. The pair of projecting portions 62 has a first projecting portion 63 and a second projecting portion 64 facing the first projecting portion 63 in a direction orthogonal to the direction in which the plurality of electric wires 10 are arranged. The first projecting portion 63 has a planar first opposing surface 63 a parallel to the direction in which the plurality of electric wires 10 are arranged. The second projecting portion 64 has a planar second opposing surface 64a parallel to the direction in which the plurality of electric wires 10 are arranged. The facing surfaces 63a and 64a of the first projecting portion 63 and the second projecting portion 64 are spaced apart by a distance L such that the portions of the collective shield member 32 interposed in pairs therebetween do not come into contact with each other.

以上説明したように、本実施形態によれば、以下の作用効果を奏することができる。
（１）各電線１０の個別シールド部材３１にまたがって装着される一括シールド部材３２を含め、接続部材６０はその一部が互いに隣り合う電線１０同士の間に向かって押し込まれる突出部６２を有する。すなわち、隣接の電線１０の個別シールド部材３１同士の間に生じる隙間（図５の隙間５６０に相当）に接続部材６０の突出部６２が存在するため、各個別シールド部材３１それぞれに一括シールド部材３２が回り込んで半周を超えるような範囲まで接触範囲を広くすることが可能となる。また、接続部材６０のかしめによる締付け時に電線１０及び個別シールド部材３１が隙間側に変形して逃げることも抑制でき、締付け力の低下も抑制できる。よって、個別シールド部材３１と一括シールド部材３２との固着力を強くすることができ、個別シールド部材３１と一括シールド部材３２との位置ずれの発生を抑制することができる。 As described above, according to this embodiment, the following effects can be obtained.
(1) The connection member 60, including the collective shield member 32 mounted across the individual shield members 31 of the electric wires 10, has a projecting portion 62 that is partially pushed between the adjacent electric wires 10. . That is, since the projecting portion 62 of the connection member 60 exists in the gap (corresponding to the gap 560 in FIG. 5) generated between the individual shield members 31 of the adjacent electric wires 10, each individual shield member 31 has a collective shield member 32. It is possible to widen the contact range to a range exceeding a half circumference. In addition, it is possible to prevent the wire 10 and the individual shield member 31 from deforming and escaping toward the gap when the connection member 60 is crimped and tightened. Therefore, the fixing force between the individual shield member 31 and the collective shield member 32 can be strengthened, and the occurrence of positional deviation between the individual shield member 31 and the collective shield member 32 can be suppressed.

（２）一括シールド部材３２は、複数の電線１０の並び方向と直交する方向に対向する第１突出部６３と第２突出部６４との両側から押し込まれる。すなわち、隣接の電線１０の個別シールド部材３１同士の間に生じる隙間それぞれに接続部材６０の第１突出部６３と第２突出部６４とが存在するため、各個別シールド部材３１それぞれと一括シールド部材３２との接触範囲を十分広くすることが可能となる。また、接続部材６０のかしめによる締付け時に電線１０及び個別シールド部材３１が隙間側に変形して逃げることも各突出部６３、６４にて抑制でき、締付け力の低下もより確実に抑制できる。よって、個別シールド部材３１と一括シールド部材３２との固着力をより強いものとすることができる。 (2) The collective shield member 32 is pushed in from both sides of the first projecting portion 63 and the second projecting portion 64 that face each other in the direction orthogonal to the direction in which the electric wires 10 are arranged. That is, since the first projecting portion 63 and the second projecting portion 64 of the connection member 60 are present in each gap generated between the individual shield members 31 of the adjacent electric wires 10, each individual shield member 31 and the collective shield member 32 can be sufficiently widened. In addition, the projections 63 and 64 can prevent the wire 10 and the individual shield member 31 from deforming toward the gap and escaping when the connection member 60 is crimped, and the reduction in tightening force can be suppressed more reliably. Therefore, the fixing force between the individual shield member 31 and the collective shield member 32 can be made stronger.

（３）第１突出部６３と第２突出部６４とが一括シールド部材３２をそれぞれ押し込む互いの対向面６３ａ、６４ａは、複数の電線１０の並び方向と平行な平面、すなわちその押し込み方向と直交する平面をなしている。このため、第１突出部６３と第２突出部６４とが一括シールド部材３２を押し込む際、一括シールド部材３２の損傷を抑制することができる。 (3) The mutually facing surfaces 63a and 64a into which the first projecting portion 63 and the second projecting portion 64 push the collective shield member 32 are planes parallel to the direction in which the plurality of wires 10 are arranged, that is, perpendicular to the pushing direction. It forms a flat surface. Therefore, when the first projecting portion 63 and the second projecting portion 64 push the collective shield member 32, damage to the collective shield member 32 can be suppressed.

（４）第１突出部６３と第２突出部６４との各対向面６３ａ、６４ａは、その間に対をなして介在する一括シールド部材３２の部位同士が接触しない間隔Ｌを有する。このため、一括シールド部材３２のその部位同士に互いに適度なスペースが得られ、一括シールド部材３２の損傷を抑制することができる。 (4) The facing surfaces 63a and 64a of the first projecting portion 63 and the second projecting portion 64 have an interval L such that the portions of the collective shield member 32 interposed in pairs therebetween do not come into contact with each other. Therefore, an appropriate space can be obtained between the portions of the collective shield member 32, and damage to the collective shield member 32 can be suppressed.

（５）接続部材６０の六角形筒状部６１にて一括シールド部材３２と各個別シールド部材３１とのかしめによる締付けが行われる。すると、電線１０及び個別シールド部材３１、更には一括シールド部材３２が円筒状から六角形筒状に倣った若干の変形を伴うため、部分的に相互間の圧接力を高めることができる。よって、個別シールド部材３１と一括シールド部材３２との固着力を高めることができる。 (5) The collective shield member 32 and the individual shield members 31 are crimped together at the hexagonal cylindrical portion 61 of the connection member 60 to be tightened. As a result, the wire 10, the individual shield member 31, and the collective shield member 32 are slightly deformed from a cylindrical shape to a hexagonal cylindrical shape, so that the pressing force between them can be partially increased. Therefore, the fixing strength between the individual shield member 31 and the collective shield member 32 can be increased.

（６）筒状部材５０により電線１０を保護できることに加え、一括シールド部材３２を含めた接続部材６０のかしめによる締付けを筒状部材５０を土台にして行えることで、個別シールド部材３１と一括シールド部材３２との固着力を高めることができる。 (6) In addition to being able to protect the electric wire 10 by the cylindrical member 50, the connection member 60 including the collective shield member 32 can be tightened by crimping using the cylindrical member 50 as a base, so that the individual shield member 31 and the collective shield The fixing force with the member 32 can be increased.

（７）剛性を有する金属製（板金製）の接続部材６０により一括シールド部材３２をかしめることで、結束バンドのような締付け部材を割愛することができる。
なお、上記実施形態は、以下のように変更して実施することができる。上記実施形態及び以下の変更例は技術的に矛盾しない範囲で組み合わせて実施することができる。 (7) By crimping the collective shield member 32 with the connection member 60 made of metal (made of sheet metal) having rigidity, a tightening member such as a binding band can be omitted.
