Description

ワイヤハーネスWire harness
 本発明は、ワイヤハーネスに関する。 The present invention relates to a wire harness.
 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。 Conventionally, for example, in a wire harness for a vehicle, an electric wire is covered with a shield member in order to shield electromagnetic noise generated when current is applied to the electric wire. The shield member is formed of a braided wire in which conductive strands such as an aluminum alloy are knitted into a cylindrical 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 the shield member is known (see, for example, Patent Document 1). Further, a collective shield member that covers a plurality of electric wires collectively with one shield member is known (for example, see Patent Document 2). Note that the end portions of the individual shield member and the collective shield member are electrically connected to the connector 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 vehicle equipment.

 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。 Incidentally, 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.
 そこで、本願発明者は、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を検討した。すなわち、図5に示すように、上記接続構造においては、電線510の絶縁被覆512と個別シールド部材530との間に金属製の筒状部材520が設けられている。なお、絶縁被覆512は、電線510の芯線511の外周を覆っている。個別シールド部材530のうち筒状部材520の外周に位置する部分が一括シールド部材540によって覆われている。一括シールド部材540及び個別シールド部材530が筒状部材520に対して外周側からバンド部材550によって締め付けられている。これにより、個別シールド部材530と一括シールド部材540とが電気的に接続される。 Therefore, the inventor of the present application examined the following connection structure for connecting the individual shield member and the collective shield member. That is, as shown in FIG. 5, in the above connection structure, a metal cylindrical member 520 is provided between the insulating coating 512 of the electric wire 510 and the individual shield member 530. Note that the insulating coating 512 covers the outer periphery of the core wire 511 of the electric wire 510. A portion of the individual shield member 530 located on the outer periphery of the cylindrical member 520 is covered with the collective shield member 540. The collective shield member 540 and the individual shield member 530 are fastened to the cylindrical member 520 by the band member 550 from the outer peripheral side. Thereby, the individual shield member 530 and the collective shield member 540 are electrically connected.
 しかしながら、こうした接続構造では、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が存在する。そのため、バンド部材550による締め付け力が不足しやすく、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 such a connection structure, there is a gap 560 where the collective shield member 540 and the individual shield member 530 do not contact each other. Therefore, the tightening force by the band member 550 is likely to be insufficient, and there is a possibility that a positional deviation in the length direction between the individual shield member 530 and the collective shield member 540 may occur.
 本発明の目的は、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のできるワイヤハーネスを提供することにある。 An object of the present invention is to provide a wire harness that can suppress the occurrence of positional deviation between an individual shield member and a collective shield member.
 上記目的を達成するため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一括シールド部材と、複数の前記電線がそれぞれ挿通され、前記電線の外周面と前記個別シールド部材の内周面との間に介在する複数の筒状部材と、前記一括シールド部材のうち前記個別シールド部材の各々を覆う部分を前記筒状部材の外周面に対して締め付ける締付部材と、を備え、前記筒状部材の外周面には、前記筒状部材の周方向に沿って延在する段差部が設けられており、前記締付部材は、前記個別シールド部材と前記一括シールド部材とを前記段差部の底面に対して締め付ける。 A wire harness for achieving the above object comprises a plurality of individual shields comprising a plurality of electric wires and a braided wire in which conductive strands are knitted into a cylindrical shape, and electromagnetically shielding the plurality of the electric wires individually by covering them A member, a braided wire in which conductive strands are knitted into a cylindrical shape, and a plurality of the wires are inserted through the collective shield member that electromagnetically shields by covering the plurality of wires together, and the wires A plurality of cylindrical members interposed between the outer peripheral surface of the individual shield member and the inner peripheral surface of the individual shield member, and a portion of the collective shield member that covers each of the individual shield members is defined with respect to the outer peripheral surface of the cylindrical member. A tightening member that is tightened in a step, and a stepped portion that extends along a circumferential direction of the tubular member is provided on an outer peripheral surface of the tubular member, and the tightening member includes the individual shield. Members and the batch Tightened and Rudo member with respect to the bottom surface of the stepped portion.
 同構成によれば、一括シールド部材のうち各個別シールド部材を覆う部分が、締付部材により各筒状部材の外周面に対して締め付けられる。このとき、各個別シールド部材及び一括シールド部材が段差部の底面に対して締め付けられることによって、各筒状部材の段差部に食い込むこととなる。このため、各個別シールド部材と一括シールド部材とのワイヤハーネスの長さ方向における位置ずれの発生を抑制することができる。 According to this configuration, the portion of the collective shield member that covers each individual shield member is fastened to the outer peripheral surface of each cylindrical member by the fastening member. At this time, the individual shield members and the collective shield member are tightened against the bottom surface of the stepped portion, so that they bite into the stepped portion of each cylindrical member. For this reason, generation | occurrence | production of the position shift in the length direction of the wire harness of each individual shield member and a package shield member can be suppressed.

 上記ワイヤハーネスにおいて、前記筒状部材の外周面には、前記段差部を有する溝部が前記筒状部材の周方向に沿って延在していることが好ましい。
Moreover, since the cylindrical member is interposed between the electric wire and the individual shield member, the electric wire can be prevented from being deformed when being tightened by the tightening member.
The said wire harness WHEREIN: It is preferable that the groove part which has the said level | step-difference part is extended along the circumferential direction of the said cylindrical member in the outer peripheral surface of the said cylindrical member.
 同構成によれば、溝部の幅方向の両側に段差部が形成されるため、各個別シールド部材と一括シールド部材との位置ずれをワイヤハーネスの長さ方向の両方向において抑制することができる。 According to this configuration, since the step portions are formed on both sides in the width direction of the groove portion, it is possible to suppress the positional deviation between each individual shield member and the collective shield member in both directions in the length direction of the wire harness.
 上記ワイヤハーネスにおいて、前記溝部は、前記筒状部材の外周面の全周にわたって設けられていることが好ましい。
 溝部が筒状部材の周方向の一部に設けられている場合には、個別シールド部材及び一括シールド部材を溝部に食い込ませるために個別シールド部材及び一括シールド部材に対して筒状部材の周方向における位置決めを行う必要が生じる。
The said wire harness WHEREIN: It is preferable that the said groove part is provided over the perimeter of the outer peripheral surface of the said cylindrical member.
When the groove portion is provided in a part of the circumferential direction of the cylindrical member, the circumferential direction of the cylindrical member with respect to the individual shield member and the collective shield member in order to bite the individual shield member and the collective shield member into the groove portion. It is necessary to perform positioning in

Moreover, a cylindrical member can be formed easily. Therefore, the wire harness can be easily manufactured.
 上記ワイヤハーネスにおいて、前記溝部の底面及び前記締付部材の内周面の少なくとも一方には、突起が設けられていることが好ましい。
 同構成によれば、溝部の底面に突起を設けた場合には、同突起が個別シールド部材や一括シールド部材に食い込むことにより、筒状部材に対する個別シールド部材や一括シールド部材の位置ずれを抑制できる。また、締結部材の内周面に突起を設けた場合には、同突起が一括シールド部材や個別シールド部材に食い込むことにより、締結部材に対する個別シールド部材や一括シールド部材の位置ずれを抑制できる。したがって、各個別シールド部材と一括シールド部材とのワイヤハーネスの長さ方向における位置ずれの発生を一層抑制することができる。
In the wire harness, it is preferable that a protrusion is provided on at least one of the bottom surface of the groove and the inner peripheral surface of the fastening member.
According to the same configuration, when the protrusion is provided on the bottom surface of the groove, the protrusion can bite into the individual shield member or the collective shield member, thereby suppressing the positional deviation of the individual shield member or the collective shield member with respect to the cylindrical member. . Moreover, when the protrusion is provided on the inner peripheral surface of the fastening member, the protrusion can bite into the collective shield member or the individual shield member, thereby suppressing the positional deviation of the individual shield member or the collective shield member with respect to the fastening member.

<Cylindrical member 50>
Between the outer peripheral surface of each electric wire 10 and the inner peripheral surface of each individual shield member 31, a cylindrical tubular member 50 through which each electric wire 10 is inserted is interposed. 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 wires 10. In addition, it is preferable that the cylindrical member 50 of this embodiment is a metal material which has rigidity, for example, is formed with the brass. In the following description, the circumferential direction of the tubular member 50 is simply referred to as the circumferential direction.
 図3に示すように、各筒状部材50の外周面には、周方向に沿って延在する溝部51が全周にわたって設けられている。すなわち、筒状部材50の外周面には、同外周面の両端部と溝部51の底面52との間に、周方向に沿って延在する一対の段差部53が設けられている。 As shown in FIG. 3, a groove 51 extending along the circumferential direction is provided on the outer peripheral surface of each cylindrical member 50 over the entire circumference. That is, on the outer peripheral surface of the cylindrical member 50, a pair of stepped portions 53 extending along the circumferential direction is provided between both end portions of the outer peripheral surface and the bottom surface 52 of the groove portion 51.
 <締付部材60>
 一括シールド部材32の接続部32cには、接続部32cを各筒状部材50の溝部51の底面52に対して締め付ける締付部材60が設けられている。締付部材60は、例えば、樹脂材料からなる周知の結束バンドである。
<Tightening member 60>
The connection portion 32 c of the collective shield member 32 is provided with a fastening member 60 that tightens the connection portion 32 c against the bottom surface 52 of the groove portion 51 of each cylindrical member 50. The fastening member 60 is, for example, a known binding band made of a resin material.
 ここで、各溝部51の幅W1は、締付部材60の幅W2よりも大きくされている(W1>W2)。
 本実施形態の作用及び効果について説明する。
Here, the width W1 of each groove part 51 is made larger than the width W2 of the fastening member 60 (W1> W2).
The operation and effect of this embodiment will be described.
 (1)ワイヤハーネスは、複数の電線10がそれぞれ挿通され、電線10の外周面と個別シールド部材31の内周面との間に介在する複数の筒状部材50、及び一括シールド部材32のうち各個別シールド部材31を覆うことで接続される接続部32cを筒状部材50の外周面に対して締め付ける締付部材60を備える。筒状部材50の外周面には、筒状部材50の周方向に沿って延在する溝部51が全周にわたって設けられている。締付部材60は、個別シールド部材31と一括シールド部材32とを溝部51の底面52に対して締め付ける。 (1) Among the plurality of cylindrical members 50 and the collective shield member 32, the wire harness is inserted between the outer peripheral surface of the electric wire 10 and the inner peripheral surface of the individual shield member 31. A fastening member 60 is provided for fastening the connection portion 32 c connected by covering each individual shield member 31 to the outer peripheral surface of the tubular member 50. On the outer peripheral surface of the cylindrical member 50, a groove portion 51 extending along the circumferential direction of the cylindrical member 50 is provided over the entire circumference. The tightening member 60 tightens the individual shield member 31 and the collective shield member 32 against the bottom surface 52 of the groove 51.
 こうした構成によれば、接続部32cが締付部材60により各筒状部材50の外周面に対して締め付けられる。このとき、各個別シールド部材31及び一括シールド部材32が撓むことによって、各筒状部材50の溝部51(段差部53)に食い込むこととなる。ここで、溝部51の幅方向の両側に段差部53が形成されるため、各個別シールド部材31と一括シールド部材32との位置ずれをワイヤハーネスの長さ方向の両方向において抑制することができる。 According to such a configuration, the connection portion 32 c is fastened to the outer peripheral surface of each tubular member 50 by the fastening member 60. At this time, each individual shield member 31 and the collective shield member 32 bend, and thus bite into the groove portion 51 (stepped portion 53) of each cylindrical member 50. Here, since the step part 53 is formed in the both sides of the width direction of the groove part 51, position shift with each individual shield member 31 and the collective shield member 32 can be suppressed in both directions of the length direction of a wire harness.
 ところで、溝部51が筒状部材50の周方向の一部に設けられている場合には、個別シールド部材31及び一括シールド部材32を溝部51に食い込ませるために個別シールド部材31及び一括シールド部材32に対して筒状部材50の周方向における位置決めを行う必要が生じる。 By the way, when the groove part 51 is provided in a part of the circumferential direction of the cylindrical member 50, the individual shield member 31 and the collective shield member 32 are used to bite the individual shield member 31 and the collective shield member 32 into the groove part 51. However, it is necessary to position the cylindrical member 50 in the circumferential direction.
 この点、上記構成によれば、溝部51が筒状部材50の外周面の全周にわたって設けられているため、上述したような筒状部材50の周方向における位置決めが不要となる。したがって、ワイヤハーネスの組立作業性を向上させることができる。また、筒状部材50を容易に形成することができるため、筒状部材50の製造コストを低減することができる。したがって、ワイヤハーネスを安価に製造することができる。 In this respect, according to the above configuration, since the groove portion 51 is provided over the entire circumference of the outer peripheral surface of the cylindrical member 50, the positioning of the cylindrical member 50 in the circumferential direction as described above becomes unnecessary. Therefore, the assembly workability of the wire harness can be improved. Moreover, since the cylindrical member 50 can be formed easily, the manufacturing cost of the cylindrical member 50 can be reduced. Therefore, the wire harness can be manufactured at low cost.
 また、筒状部材50が電線10と個別シールド部材31との間に介在していることから、締付部材60により締め付けられる際に電線10が変形することを抑制できる。
