このワイヤハーネス1は、例えば、プラス回路やマイナス回路を構成する高圧電線と、オプション回路や分割回路を構成する低圧電線とを有しており、少なくとも高圧電線の両端部が電動モータ13側とバッテリ15側とにそれぞれ接続され、車両11の床下に配索される。 The wire harness 1 includes, for example, a high-voltage electric wire forming a plus circuit or a minus circuit and a low-voltage electric wire forming an option circuit or a division circuit, and at least both ends of the high-voltage electric wire are on the electric motor 13 side and the battery. 15 side, and is installed under the floor of the vehicle 11.

以下、図1,図2を用いてワイヤハーネス1の詳細について説明する。 Hereinafter, the details of the wire harness 1 will be described with reference to FIGS. 1 and 2.

図1,図2に示すように、ワイヤハーネス1は、複数の電線3と、複数のシールド部材5と、接地部7と、接続部9とを備えている。 As shown in FIGS. 1 and 2, the wire harness 1 includes a plurality of electric wires 3, a plurality of shield members 5, a ground portion 7, and a connecting portion 9.

複数(ここでは2本)の電線3は、例えば、電動モータ13とバッテリ15との間を電気的に接続し、プラス回路やマイナス回路を構成する高圧電線、或いは電動モータ13とバッテリ15との間や他の電気部品の間の情報を伝達する信号線や他の電気部品の間を電気的に接続する幹線から分岐された分岐線などのオプション回路や分割回路を構成する低圧電線などからなる。 A plurality of (here, two) electric wires 3 electrically connect between the electric motor 13 and the battery 15 to form a plus circuit or a minus circuit, or the electric motor 13 and the battery 15, for example. Signal lines that transmit information between devices and other electrical parts, and low voltage wires that configure optional circuits such as branch lines that branch from a trunk line that electrically connects other electrical parts and split circuits ..

この複数の電線3は、電線3へのノイズなどの侵入や電線3からのノイズなどの漏洩を防止するために、その外周がシールド部材5によって覆われている。 The outer circumference of each of the plurality of electric wires 3 is covered with a shield member 5 in order to prevent noise from entering the electric wires 3 and leakage of noise from the electric wires 3.

なお、シールド部材5の内部に配置される電線3は、1本でもよいが、これに限らず、例えば、プラス回路とマイナス回路とを構成する2本の高圧電線の外周に1つのシールド部材5を配置させてもよい。 The number of the electric wire 3 arranged inside the shield member 5 may be one, but not limited to this. For example, one shield member 5 is provided on the outer circumference of two high voltage electric wires forming a plus circuit and a minus circuit. May be arranged.

シールド部材5は、導電性材料からなる複数の素線が編み込まれて形成された編組からなり、それぞれの電線3の外周を覆うように複数(ここでは2つ)が並列に配置されている。 The shield member 5 is made of a braid formed by braiding a plurality of elemental wires made of a conductive material, and a plurality (two here) are arranged in parallel so as to cover the outer circumference of each electric wire 3.

このシールド部材5は、車両11の車体ボディにボルトなどを介して接続される接地端子17や電気部品に設けられた導電部材に接続されるシールドシェル19が設けられた接地部7を介して接地されることにより、シールド回路を形成する。 The shield member 5 is grounded via a ground terminal 17 connected to the vehicle body of the vehicle 11 via a bolt or the like and a ground portion 7 provided with a shield shell 19 connected to a conductive member provided in an electric component. By doing so, a shield circuit is formed.

このようにシールド部材5がシールド回路を形成することにより、電線3へのノイズなどの侵入や電線3からのノイズなどの漏洩を防止することができる。 By thus forming the shield circuit by the shield member 5, it is possible to prevent noise from entering the electric wire 3 and leakage of noise from the electric wire 3.

ところで、従来、本実施の形態のように、シールド部材5が2つある場合には、1つのシールド部材5の両端部にそれぞれ接地端子17やシールドシェル19からなる接地部7,7を設け、全体として4つの接地部7を設けていた。 By the way, conventionally, in the case where there are two shield members 5 as in the present embodiment, the ground portions 7, 7 including the ground terminal 17 and the shield shell 19 are provided at both ends of one shield member 5, respectively. Four grounding parts 7 were provided as a whole.

このため、接地部7としての接地端子17やシールドシェル19の部品点数、シールド部材5と接地端子17やシールドシェル19とを接続する作業や接地端子17やシールドシェル19を接地させる作業などの作業工数が増大していた。 Therefore, the number of parts of the ground terminal 17 and the shield shell 19 as the ground portion 7, the work of connecting the shield member 5 to the ground terminal 17 and the shield shell 19, the work of grounding the ground terminal 17 and the shield shell 19, and the like. The man-hour was increasing.

そこで、ワイヤハーネス1では、シールド部材5,5の一端側に接地部7,7を設け、シールド部材5,5の他端側に、シールド部材5,5同士を接続する接続部9を設けている。 Therefore, in the wire harness 1, the grounding portions 7, 7 are provided on one end side of the shield members 5, 5 and the connecting portion 9 for connecting the shield members 5, 5 is provided on the other end side of the shield members 5, 5. There is.

一方のシールド部材5(ここでは図2の上側に位置するシールド部材5)の一端側に設けられた接地部7は、シールドシェル19からなり、他方のシールド部材5(ここでは図2の下側に位置するシールド部材5)の一端側に設けられた接地部7は、接地端子17からなる。 The grounding portion 7 provided on one end side of one shield member 5 (here, the shield member 5 located on the upper side in FIG. 2) is composed of a shield shell 19, and the other shield member 5 (here, the lower side on FIG. 2).

この接続部9は、隣り合うシールド部材5,5を電気的に接続できればよく、接地される必要はない。 The connecting portion 9 need only be capable of electrically connecting the adjacent shield members 5 and 5, and need not be grounded.

このように接続部9で隣り合うシールド部材5,5を接続することにより、2つのシールド部材5,5を、電気的に接続された1つのシールド部材5とすることができる。 By thus connecting the adjacent shield members 5 and 5 at the connecting portion 9, the two shield members 5 and 5 can be made into one electrically connected shield member 5.

このため、2つのシールド部材5,5の一端側に設けられた接地部7,7を接地させることで、2つのシールド部材5,5のそれぞれにシールド回路を形成することができる。 Therefore, by grounding the grounding portions 7, 7 provided on one end side of the two shield members 5, 5, a shield circuit can be formed in each of the two shield members 5, 5.

このようにシールド部材5,5の一端側に接地部7,7を設け、シールド部材5,5の他端側に、シールド部材5,5同士を接続する接続部9を設けることにより、接地部7を削減することができ、その作業工数を削減することができる。 In this way, by providing the grounding portions 7, 7 on one end side of the shield members 5, 5, and by providing the connecting portion 9 for connecting the shield members 5, 5 to each other on the other end side of the shield members 5, 5, 7 can be reduced, and the number of man-hours can be reduced.

加えて、接続部9は、隣り合うシールド部材5,5を接続させればよく、接地させる必要がないので、接続部9をシールド部材5に接続させる接続作業だけでよく、さらに作業工数を削減することができる。 In addition, the connecting portion 9 only needs to connect the adjacent shield members 5 and 5 and does not need to be grounded. Therefore, only connecting work for connecting the connecting portion 9 to the shield member 5 is required, and the number of work steps is further reduced. can do.

さらには、接地部7を削減することができるので、接地部7が接続される側の車両11の接続スペースを削減して省スペース化を図ることができると共に、部品点数を削減して軽量化を図ることができる。 Furthermore, since the grounding part 7 can be reduced, the connection space of the vehicle 11 on the side to which the grounding part 7 is connected can be reduced to save space, and the number of parts can be reduced to reduce the weight. Can be planned.

このようなワイヤハーネス1では、複数のシールド部材5のうち少なくとも2つのシールド部材5の端部に接続されて接地される接地部7と、隣り合うシールド部材5,5の端部の間に配置され隣り合うシールド部材5,5を接続する接続部9とを有するので、接続部9で接続されたシールド部材5の端部を接地する必要がない。 In the wire harness 1 as described above, the plurality of shield members 5 are arranged between the end portions of the adjacent shield members 5 and 5 and the ground portion 7 that is connected to the end portions of at least two shield members 5 and is grounded. Since it has the connection part 9 which connects the adjacent shield members 5 and 5, it is not necessary to ground the end part of the shield member 5 connected by the connection part 9.

従って、このようなワイヤハーネス1では、隣り合うシールド部材5,5を接続部9で接続することにより、シールド部材5の接地部7を設ける箇所を削減し、接地部7の部品点数や接地部7を設けるための作業工数を削減でき、低コスト化することができる。 Therefore, in such a wire harness 1, by connecting the adjacent shield members 5 and 5 at the connection portion 9, the number of places where the ground portion 7 of the shield member 5 is provided is reduced, and the number of parts of the ground portion 7 and the ground portion are reduced.

なお、2つのシールド部材5,5の一端側と他端側に設けられる接地部7,7を両方とも、シールドシェル19、或いは接地端子17としてもよい。 It should be noted that both the ground portions 7, 7 provided on one end side and the other end side of the two shield members 5, 5 may be the shield shell 19 or the ground terminal 17.

一方、複数のシールド部材5のうち接地部7,7が設けられたシールド部材5,5以外のシールド部材5(ここでは図4の中央に位置するシールド部材5)の一端側と他端側の両端部は、それぞれリングスリーブなどからなる接続部9を介して隣り合うシールド部材5,5(ここでは図4の上側と下側に位置するシールド部材5,5)の端部(接地部7,7が設けられていない側の端部)に接続されている。 On the other hand, one end side and the other end side of the shield member 5 (here, the shield member 5 located in the center of FIG. 4) other than the shield members 5 and 5 provided with the grounding portions 7 and 7 among the plurality of shield members 5 are provided. Both end portions are the end portions (ground portion 7, ground portion 7, of the shield members 5 and 5 (here, shield members 5 and 5 located on the upper side and the lower side in FIG. 4, respectively) that are adjacent to each other via a connecting portion 9 formed of a ring sleeve or the like. 7 is connected to the end portion on the side not provided).

この接続部9,9は、隣り合うシールド部材5,5を電気的に接続できればよく、接地される必要はない。 The connecting portions 9, 9 need only be capable of electrically connecting the adjacent shield members 5, 5 and need not be grounded.

このように接続部9,9で一端側と他端側とで交互に隣り合うシールド部材5,5を接続することにより、複数(ここでは3つ)のシールド部材5を、電気的に接続された1つのシールド部材5とすることができる。 In this way, by connecting the shield members 5 and 5 that are alternately adjacent to each other on the one end side and the other end side at the connecting portions 9 and 9, a plurality (here, three) of shield members 5 are electrically connected. There can be only one shield member 5.

このため、複数のシールド部材5のうち外側(ここでは図4の上側と下側)に位置する2つのシールド部材5,5の接続部9と反対側に設けられた接地部7,7を接地させることで、複数のシールド部材5のそれぞれにシールド回路を形成することができる。 Therefore, the grounding portions 7, 7 provided on the opposite side of the connection portion 9 of the two shield members 5, 5 located on the outer side (here, the upper side and the lower side in FIG. 4) of the plurality of shield members 5 are grounded. By doing so, a shield circuit can be formed in each of the plurality of shield members 5.

このように外側に位置する2つのシールド部材5,5の端部に接地部7,7を設け、隣り合うシールド部材5,5を接続部9,9で接続することにより、接地部7を2箇所とすることができ、接地部7を大幅に削減することができ、その作業工数も大幅に削減することができる。 In this way, the grounding portions 7 and 7 are provided at the ends of the two shield members 5 and 5 located on the outer side, and the adjacent shield members 5 and 5 are connected by the connecting portions 9 and 9. The number of the grounding portions 7 can be significantly reduced, and the number of working steps can be significantly reduced.

一方、接続部9を設ける箇所は、隣り合うシールド部材5,5の間の数分(ここでは2箇所分)であり、接続部9は、隣り合うシールド部材5,5を接続させればよく、接地させる必要がないので、シールド部材5の両端部に接地部7を設ける場合に比較して、大幅に作業工数を削減することができる。 On the other hand, the locations where the connecting portions 9 are provided are a few minutes (here, two locations) between the adjacent shield members 5 and 5, and the connecting portions 9 may connect the adjacent shield members 5 and 5. Since there is no need to ground, the work man-hours can be significantly reduced as compared with the case where the grounding portions 7 are provided at both ends of the shield member 5.

このようなワイヤハーネス201では、接地部7を設ける箇所を2箇所とし、接続部9を設ける箇所を複数のシールド部材5のうち隣り合うシールド部材5,5の間の数分(ここでは2箇所分)とすることができ、部品点数や作業工数を削減することができる。 In such a wire harness 201, the place where the grounding portion 7 is provided is two, and the place where the connecting portion 9 is provided is the same as the number of adjacent shield members 5 and 5 among the plurality of shield members 5 (here, two places). It is possible to reduce the number of parts and work man-hours.

なお、本発明の実施の形態に係るワイヤハーネスでは、シールド部材が編組となっているが、これに限らず、シールド部材を金属箔としてもよく、シールド回路を形成できるものであれば、シールド部材はどのような形態であってもよい。 In the wire harness according to the embodiment of the present invention, the shield member is braided, but not limited to this, the shield member may be a metal foil, as long as the shield circuit can be formed, the shield member May have any form.

また、シールド部材は、2つ、或いは3つ配置されているが、これに限らず、シールド部材を4つ以上配置してもよい。 Further, although two or three shield members are arranged, the number of shield members is not limited to this, and four or more shield members may be arranged.
