Description

配線具及びワイヤハーネスWiring tool and wire harness
　本発明は、電線を予め定められた形状で保持する配線具及びそれを備えたワイヤハーネスに関する。 The present invention relates to a wiring tool for holding an electric wire in a predetermined shape and a wire harness including the wiring tool.
　自動車などの車両に搭載されるワイヤハーネスは、電線に取り付けられた樹脂製の配線具を備え、電線がその配線具によって予め定められた経路に沿って保持された状態で敷設されることが多い。例えば、従来の一般的なワイヤハーネスにおいて、電線は、粘着テープ又はベルト部材などの結束材によって板状又は棒状の樹脂部材に固定される。これにより、電線は、予め定められた形状で保持される。 A wire harness mounted on a vehicle such as an automobile includes a resin wiring tool attached to an electric wire, and the electric wire is often laid in a state where the electric wire is held along a predetermined route by the wiring tool. . For example, in a conventional general wire harness, an electric wire is fixed to a plate-shaped or rod-shaped resin member by a binding material such as an adhesive tape or a belt member. Thereby, the electric wire is held in a predetermined shape.
　また、特許文献１に示されるワイヤハーネスは、電線束を挟み込む状態で熱プレスによって固着された２つの板状の樹脂部材からなる配線具を備える。一方の樹脂部材は、平板状の基部と基部から起立するリブとからなる基体である。他方の樹脂部材は、基体のリブが挿入される貫通孔が形成され、基体に重ねられた状態で基体の基部に固着される平板状の被覆体である。 Moreover, the wire harness shown in Patent Document 1 includes a wiring tool made of two plate-like resin members fixed by heat pressing in a state where the wire bundle is sandwiched. One resin member is a base body composed of a flat base portion and ribs rising from the base portion. The other resin member is a flat cover that is formed with a through-hole into which the rib of the base is inserted and is fixed to the base of the base in a state of being superimposed on the base.
　特許文献１に示される配線具において、基体のリブは、配線経路の両側に形成され、配線のガイド部として機能する。また、特許文献１に示されるワイヤハーネスにおいて、電線の中間部分は、基体と被覆体との間に挟み込まれる。さらに、電線における基体から基体の外側へ亘って配置される部分は、結束材で基体の外縁部分に形成された庇部と結束されることによってその庇部に固定される。庇部は、基体の外縁部分における外側へ張り出した部分である。 In the wiring tool disclosed in Patent Document 1, the ribs of the base are formed on both sides of the wiring path and function as a wiring guide. Moreover, in the wire harness shown by patent document 1, the intermediate part of an electric wire is inserted | pinched between a base | substrate and a covering. Furthermore, the part arrange | positioned from the base | substrate to the outer side of a base | substrate in an electric wire is fixed to the collar part by binding with the collar part formed in the outer edge part of the base | substrate with the binding material. The collar portion is a portion protruding outward in the outer edge portion of the base.
　ところで、ワイヤハーネスの形状において特に重要なことは、各電線が、接続相手に近い予め定められた基準位置から予め定められた長さで存在することである。ここで、接続相手は、電装機器又は他の電線の端部に設けられたコネクタなどである。 By the way, what is particularly important in the shape of the wire harness is that each electric wire exists in a predetermined length from a predetermined reference position close to the connection partner. Here, the connection partner is an electrical equipment or a connector provided at the end of another electric wire.
　例えば、自動車の座席の下側に配置されるワイヤハーネスにおいては、各電線の端部のコネクタが、座席駆動用のモータなどの機器又は他の電線のコネクタに対して過不足なく届くように、各電線における端部のコネクタまたはコネクタに近い部分が、予め定められた位置（基準位置）に固定されることが重要である。 For example, in the wire harness arranged under the seat of an automobile, the connector at the end of each electric wire can reach the device such as a motor for driving the seat or the connector of another electric wire without excess or deficiency. It is important that the connector at the end of each electric wire or a portion close to the connector is fixed at a predetermined position (reference position).
　一方、ワイヤハーネスにおいて、基準位置に至るまでの途中の電線の経路は、比較的許容範囲の広い既定の領域内に収まっていればよいことがある。例えば、自動車の座席の下側に配置されるワイヤハーネスにおいては、各電線における基準位置に至るまでの途中の部分は、座席駆動用のモータなどの機器と座席との間の空間内に収まっていれば、任意の経路での配線が許容される。 On the other hand, in the wire harness, the route of the wire on the way to the reference position may be within a predetermined area having a relatively wide allowable range. For example, in a wire harness placed under the seat of an automobile, the middle part of each wire to the reference position is within the space between the seat drive motor and other equipment. If so, wiring in an arbitrary route is allowed.

　特許文献１の配線具が採用された場合、電線は、基体の外縁部分に形成された庇部において、結束材により固定される。しかしながら、この場合、結束材が、振動などによって基体の庇部から外れやすい。結束材が基体から外れると、電線における基体からはみ出した末端側の部分の長さが、予め定められた長さで保持されなくなり、配線具の重要な目的が達成されない。 When the wiring tool disclosed in Patent Document 1 is adopted, the electric wire is fixed by a binding material at a collar portion formed on the outer edge portion of the base. However, in this case, the binding material is likely to come off from the base of the base body due to vibration or the like. When the binding material is detached from the base, the length of the end portion of the electric wire that protrudes from the base is not held at a predetermined length, and the important purpose of the wiring tool is not achieved.
　一方、結束材が通される２つの貫通孔が基体の縁部に形成されていれば、結束材が基体の庇部から外れることは防がれる。しかしながら、結束材を折り返して曲げつつ、結束材の端部を２つの貫通孔各々に順次通す作業は煩雑である。 On the other hand, if the two through holes through which the binding material is passed are formed at the edge of the base, the binding material can be prevented from coming off the base of the base. However, the operation of sequentially passing the end of the binding material through each of the two through holes while folding the binding material back is complicated.
　本発明は、結束材で固定された電線を予め定められた形状で保持し、また、保護する配線具において、電線と配線具とを結束する作業の工数を軽減しつつ、結束材が配線具から外れないようにできることを目的とする。 The present invention relates to a wiring tool that holds and protects an electric wire fixed with a binding material in a predetermined shape and reduces the man-hours for binding the electric wire and the wiring tool while the binding material is used as the wiring tool. The purpose is to be able to keep from falling out of
　本発明に係る配線具は、電線を予め定められた形状で保持する板状の部材を備えた配線具であり、その板状の部材は以下に示される各構成要素を備える。
（１）第１の構成要素は、電線が配置される配線空間に面した配線部である。
（２）第２の構成要素は、配線部の外側に形成され当該板状の部材の外縁部分をなす枠部である。
（３）第３の構成要素は、枠部の一部に形成され、配線部から枠部へ亘って配置される電線が固定される電線固定部である。この電線固定部は、電線通過部と第１の結束材通過部と第２の結束材通過部とを備える。電線通過部は、枠部における電線が通る部分である。第１の結束材通過部は、枠部における電線通過部に隣接し、電線と電線通過部とを結束する結束材の巻き付け部が貫通可能な貫通孔が形成された部分である。また、第２の結束材通過部は、枠部における電線通過部に対し第１の結束材通過部の側の反対側に隣接し、結束材の巻き付け部の厚みよりも大きな幅で枠部における外縁から内側へ切れ込む切れ込み部が形成された部分である。 The wiring tool which concerns on this invention is a wiring tool provided with the plate-shaped member which hold | maintains an electric wire with a predetermined shape, and the plate-shaped member is provided with each component shown below.
(1) A 1st component is the wiring part which faced the wiring space where an electric wire is arrange | positioned.
(2) The second component is a frame portion that is formed outside the wiring portion and forms the outer edge portion of the plate-like member.
(3) A 3rd component is an electric wire fixing part which is formed in a part of frame part and the electric wire arrange | positioned ranging from a wiring part to a frame part is fixed. The electric wire fixing portion includes an electric wire passage portion, a first binding material passage portion, and a second binding material passage portion. The electric wire passage portion is a portion through which the electric wire passes through the frame portion. The 1st binding material passage part is a part in which the penetration hole which adjoins the electric wire passage part in a frame part, and can penetrate the winding part of the binding material which binds an electric wire and an electric wire passage part was formed. Further, the second binding material passage portion is adjacent to the wire passage portion in the frame portion on the opposite side of the first binding material passage portion side, and has a width larger than the thickness of the binding material winding portion in the frame portion. It is the part where the notch which cuts inward from an outer edge was formed.
　また、本発明に係る配線具において、第２の結束材通過部の切れ込み部が、以下に示される外側孔部と内側孔部とにより構成されていることが考えられる。外側孔部は、枠部における外縁から内側へ切れ込んで形成されたスリット状の孔である。また、内側孔部は、外側孔部と連通し、第１の結束材通過部の貫通孔に対して電線通過部を挟んで対向する位置に形成され、外側孔部から電線通過部側へ段差を経て幅が拡がって形成された孔である。 Further, in the wiring tool according to the present invention, it is conceivable that the cut portion of the second binding material passage portion is constituted by an outer hole portion and an inner hole portion described below. The outer hole portion is a slit-shaped hole formed by cutting inward from the outer edge of the frame portion. The inner hole portion communicates with the outer hole portion and is formed at a position facing the through hole of the first binding material passage portion with the electric wire passage portion interposed therebetween, and a step from the outer hole portion to the electric wire passage portion side. It is a hole formed by expanding the width through the above.
　また、本発明に係る配線具において、電線通過部における貫通孔と切れ込み部との間の部分に、電線が通過する側の反対側の面において突出する突起部が形成されていることが考えられる。 Moreover, in the wiring tool which concerns on this invention, it is possible that the protrusion part which protrudes in the surface on the opposite side to the side through which an electric wire passes is formed in the part between the through-hole and notch part in an electric wire passage part. .
　また、本発明は、本発明に係る配線具と、その配線具の電線固定部に固定された電線と、電線固定部における電線通過部と電線とを結束する結束材とを備えるワイヤハーネスの発明として捉えられてもよい。 Moreover, this invention is invention of a wire harness provided with the wiring tool which concerns on this invention, the electric wire fixed to the electric wire fixing part of the wiring tool, and the binding material which binds the electric wire passage part and electric wire in an electric wire fixing part. May be taken as
　本発明において、電線固定部における貫通孔の縁部は、結束材に引っ掛かり、振動などによって電線に対する結束材の位置が移動し、結束材が配線具から外れることを防止する。そのため、電線は、電線固定部において安定的に強固に固定される。また、結束材の先端を貫通孔に挿入する作業の回数が１回で済み、２つの貫通孔に結束材を通す場合に比べ、結束作業の工数が軽減される。 In the present invention, the edge of the through hole in the electric wire fixing portion is caught by the binding material, and the position of the binding material relative to the electric wire is moved by vibration or the like, thereby preventing the binding material from coming off the wiring tool. Therefore, the electric wire is stably and firmly fixed at the electric wire fixing portion. In addition, the number of operations for inserting the tip of the binding material into the through hole is one, and the number of man-hours for the binding operation is reduced as compared with the case where the binding material is passed through the two through holes.
　また、本発明において、第２の結束材通過部の切れ込み部が、スリット状の外側孔部と、その外側孔部から段差を経て幅が拡がって形成された内側孔部とにより構成されていれば、結束材は、電線通過部の両側において、貫通孔の縁部と切れ込み部の段差とに引っ掛かる。これにより、結束材の位置ずれが、より確実に防止される。 Further, in the present invention, the cut portion of the second binding material passage portion is constituted by a slit-like outer hole portion and an inner hole portion formed by expanding the width from the outer hole portion through a step. For example, the binding material is caught on the edge portion of the through hole and the step of the cut portion on both sides of the wire passage portion. Thereby, position shift of a binding material is prevented more reliably.
　また、電線通過部に、電線が通過する側の反対側の面において突出する突起部が形成されていれば、結束材が、貫通孔の縁部及び切れ込み部の縁部において急峻に折れ曲がりにくい。即ち、結束材は、より円形に近い形で電線通過部と電線とを結束できる。その結果、結束材によって電線と電線通過部とをより強固に結束することが可能となる。 In addition, if the wire passage portion is formed with a protruding portion that protrudes on the surface opposite to the side through which the wire passes, the binding material is not easily bent sharply at the edge of the through hole and the edge of the notch. That is, the binding material can bind the electric wire passage part and the electric wire in a shape closer to a circle. As a result, it becomes possible to bind the electric wire and the electric wire passage part more firmly by the binding material.

　図５に示されるように、カバー部２を構成する対向壁部２１は、ベース部１の配線部１１に対して配線空間９０を隔てて対向する部分である。対向壁部２１には、配線空間９０を区分する仕切は形成されていない。本実施形態における対向壁部２１は、その全体が平板状に形成されている。しかしながら、ベース部１における配線部１１の凸部１１１と同様の凸部が、対向壁部２１に形成されることも考えられる。 As shown in FIG. 5, the facing wall portion 21 constituting the cover portion 2 is a portion facing the wiring portion 11 of the base portion 1 with a wiring space 90 therebetween. A partition that divides the wiring space 90 is not formed in the facing wall portion 21. The entire opposing wall 21 in the present embodiment is formed in a flat plate shape. However, it is also conceivable that a convex portion similar to the convex portion 111 of the wiring portion 11 in the base portion 1 is formed on the opposing wall portion 21.
　カバー部２を構成する第二段差部２２は、対向壁部２１の外縁に沿って形成されるとともに対向壁部２１からベース部１の反対側へ起立して段差を形成する部分である。換言すれば、対向壁部２１の外縁は、第二段差部２２の内縁に沿って形成されている。本実施形態における第二段差部２２は、表面が対向壁部２１の縁から末広がりに傾斜して形成されている。 The second step portion 22 constituting the cover portion 2 is a portion that is formed along the outer edge of the facing wall portion 21 and rises from the facing wall portion 21 to the opposite side of the base portion 1 to form a step. In other words, the outer edge of the opposing wall portion 21 is formed along the inner edge of the second step portion 22. The second step portion 22 in the present embodiment is formed such that the surface is inclined from the edge of the opposing wall portion 21 to the end.
　図１に示される例では、第二段差部２２は、全体が一定の高さで形成されている。しかしながら、第二段差部２２が、一部に他の部分よりも高く形成された部分を含むことも考えられる。 In the example shown in FIG. 1, the entire second step portion 22 is formed with a constant height. However, it is also conceivable that the second step portion 22 includes a portion formed in a part higher than the other portions.
　カバー部２を構成する第二枠部２３は、第二段差部２２の外縁に沿って形成された部分であり、カバー部２の外縁部分をなす。第二枠部２３は、平板状に形成されることの他、平坦な部分と凹部もしくは凸部とが混在する形状で形成されることも考えられる。図１に示される例では、第二枠部２３の一部に、ベース部１側へ突出する凸部が形成されている。なお、カバー部２に形成された仮留め用凸部２６についての説明は後に示す。 The second frame part 23 constituting the cover part 2 is a part formed along the outer edge of the second step part 22, and forms the outer edge part of the cover part 2.

Similarly, the second step portion 22 of the cover portion 2 also functions as a reinforcing portion that enhances the rigidity of the plate-like cover portion 2 that is uneven. Therefore, the base portion 1 and the cover portion 2 can ensure high rigidity even if the thickness is relatively small for space saving and weight reduction. Therefore, the wiring tool 10 can be reduced in space and weight.

　接続部３が溝に沿って折り返されると、カバー部２が、ベース部１に対して予め定められた位置で重なる。 When the connecting portion 3 is folded along the groove, the cover portion 2 overlaps the base portion 1 at a predetermined position.
　以上に示したように、配線具１０において、ベース部１及びカバー部２が、曲げ変形可能な接続部３と連なって一体に形成されている。そのため、部品点数が少なくなり、配線具１０を電線９に取り付けるための工数がより簡素化される。 As described above, in the wiring tool 10, the base portion 1 and the cover portion 2 are formed integrally with the connection portion 3 that can be bent and deformed. Therefore, the number of parts is reduced, and the man-hour for attaching the wiring tool 10 to the electric wire 9 is further simplified.

A temporary fastening mechanism is configured.
　仮留め用凸部２６の側面の外形は、わずかに圧縮した状態で仮留め用凹部１６の内壁面に内接する形状で形成されている。これにより、仮留め用凸部２６が、仮留め用凹部１６へ押し入れられると、仮留め用凸部２６の側面と仮留め用凹部１６の内壁面との摩擦抵抗により、カバー部２は、ベース部１の配線部１１を覆う状態でベース部１に対して留められる。 The outer shape of the side surface of the temporary fixing convex portion 26 is formed in a shape inscribed in the inner wall surface of the temporary fixing concave portion 16 in a slightly compressed state. As a result, when the temporary fixing convex portion 26 is pushed into the temporary fixing concave portion 16, the cover portion 2 is formed into the base due to the frictional resistance between the side surface of the temporary fixing convex portion 26 and the inner wall surface of the temporary fixing concave portion 16. It is fastened to the base part 1 in a state of covering the wiring part 11 of the part 1.

A temporary fastening mechanism is configured.
　なお、図１に示される例では、仮留め用凹部１６がベース部１側に設けられ、仮留め用凸部２６がカバー部２側に設けられているが、その逆の構成も考えられる。即ち、仮留め用凹部１６がカバー部２側に設けられ、仮留め用凸部２６がベース部１側に設けられてもよい。また、ベース部１及びカバー部２の各々において、仮留め用凹部１６と仮留め用凸部２６とが混在してもよい。 In the example shown in FIG. 1, the temporary fastening concave portion 16 is provided on the base portion 1 side and the temporary fastening convex portion 26 is provided on the cover portion 2 side, but the reverse configuration is also conceivable. That is, the temporary fastening concave portion 16 may be provided on the cover portion 2 side, and the temporary fastening convex portion 26 may be provided on the base portion 1 side. Moreover, in each of the base part 1 and the cover part 2, the temporary fixing concave part 16 and the temporary fixing convex part 26 may be mixed.

The cut portion 143 is formed in a portion adjacent to the side opposite to the side where the through hole 142 is located with respect to the wire passage portion 141 in the first frame portion 13.
　貫通孔１４２及び切れ込み部１４３は、例えば、真空成形される前の平板状の樹脂部材に対するトムソン加工などによって形成される。 The through-hole 142 and the cut portion 143 are formed by, for example, Thomson processing on a flat resin member before being vacuum-formed.
　図６に示される例では、切れ込み部１４３は、第一枠部１３における外縁から内側へ切れ込んで形成されたスリット状の外側孔部１４３１と、外側孔部１４３１と連通し外側孔部１４３１の幅よりも広い幅の孔である内側孔部１４３２とにより構成されている。 In the example shown in FIG. 6, the notch portion 143 includes slit-like outer hole portions 1431 formed by cutting inward from the outer edge of the first frame portion 13, and the width of the outer hole portion 1431 communicating with the outer hole portion 1431. The inner hole portion 1432 is a wider hole.
　内側孔部１４３２は、貫通孔１４２に対して電線通過部１４１を挟んで対向する位置に形成され、外側孔部１４３１から電線通過部１４１側へ幅が拡がって形成されている。そのため、外側孔部１４３１における電線通過部１４１側の縁と内側孔部１４３２における電線通過部１４１側の縁との境界部分には、段差１４３３が形成されている。即ち、内側孔部１４３２は、外側孔部１４３１から電線通過部１４１側へ段差１４３３を経て幅が拡がって形成されている。 The inner hole portion 1432 is formed at a position facing the through hole 142 with the electric wire passage portion 141 interposed therebetween, and is formed with a width expanding from the outer hole portion 1431 to the electric wire passage portion 141 side. Therefore, a step 1433 is formed at the boundary portion between the edge of the outer hole portion 1431 on the wire passage portion 141 side and the edge of the inner hole portion 1432 on the wire passage portion 141 side. In other words, the inner hole portion 1432 is formed so as to expand in width from the outer hole portion 1431 toward the electric wire passage portion 141 through the step 1433.
　結束ベルト８は、まず、切れ込み部１４３における外側孔部１４３１から内側孔部１４３２へ通される。その後、結束ベルト８は、先端が貫通孔１４２に通されるとともに、電線通過部１４１と電線通過部１４１に配置された電線９とに巻き付けられる。 The binding belt 8 is first passed from the outer hole 1431 in the notch 143 to the inner hole 1432. Thereafter, the binding belt 8 is wound around the electric wire passage portion 141 and the electric wire 9 disposed in the electric wire passage portion 141 while the tip is passed through the through hole 142.
　以上のようにして取り付けられた結束ベルト８は、図７に示されるように、電線９と電線通過部１４１とを結束した状態で保持され、電線９は、電線結束部１４の電線通過部１４１に固定される。 As shown in FIG. 7, the binding belt 8 attached as described above is held in a state where the electric wire 9 and the electric wire passage portion 141 are bound, and the electric wire 9 is held in the electric wire passage portion 141 of the electric wire binding portion 14. Fixed to.
　図６に示される電線結束部１４において、貫通孔１４２の縁部及び切れ込み部１４３の段差１４３３の部分は、振動などによって電線９に対する結束ベルト８の位置が移動し、結束ベルト８が第一枠部１３から外れることを防止する。 In the wire binding portion 14 shown in FIG. 6, the edge of the through hole 142 and the step 1433 portion of the notch 143 move the position of the binding belt 8 with respect to the wire 9 due to vibration or the like. It is prevented from coming off from the part 13.
　また、配線具１０に適用可能な電線結束部１４の他の例としては、図１２に示される第１の応用例、及び図１３に示される第２の応用例などが考えられる。 Further, as another example of the electric wire binding portion 14 applicable to the wiring tool 10, a first application example shown in FIG. 12, a second application example shown in FIG.
　図１２は、配線具１０に適用可能な第１の応用例に係る電線結束部１４の平面図である。図１２に示される電線結束部１４は、第二ベルト通過部１４３０が形成する切れ込み部１４３全体が、第一枠部１３における外縁から内側へスリット状に切れ込んで形成された孔である。 FIG. 12 is a plan view of the wire binding portion 14 according to a first application example applicable to the wiring tool 10. The wire binding portion 14 shown in FIG. 12 is a hole formed by slitting the entire cut portion 143 formed by the second belt passage portion 1430 inward from the outer edge of the first frame portion 13 in a slit shape.
　図１２に示される電線結束部１４は、図６に示される段差１４３３によって結束ベルト８の位置ずれを防ぐ構造を備えていない。しかしながら、結束ベルト８が貫通孔１４２の縁部に引っ掛かるため、少なくとも結束ベルト８が第一枠部１３から外れることは防止される。図１２に示されるような電線結束部１４が、配線具１０に採用されることも考えられる。 12 does not have a structure that prevents the binding belt 8 from being displaced by the step 1433 shown in FIG. However, since the binding belt 8 is caught by the edge portion of the through hole 142, at least the binding belt 8 is prevented from being detached from the first frame portion 13. It is also conceivable that the wire binding portion 14 as shown in FIG.
　図１３は、配線具１０に適用可能な第２の応用例に係る電線結束部１４の正面図である。なお、図１３において、電線結束部１４に固定された電線９の端部は省略されて電線９の断面が示されている。 FIG. 13 is a front view of the wire binding part 14 according to a second application example applicable to the wiring tool 10. In FIG. 13, the end portion of the electric wire 9 fixed to the electric wire binding portion 14 is omitted, and a cross section of the electric wire 9 is shown.
　図１３に示される電線結束部１４は、図６又は図１２に示される電線結束部１４の構成に対し、突起部１４４が追加された構成を有している。この突起部１４４は、電線通過部１４１における貫通孔１４２と切れ込み部１４３との間の部分に形成されており、電線９が通過する側の反対側の面において突出する部分である。 13 has a configuration in which a protruding portion 144 is added to the configuration of the wire binding portion 14 shown in FIG. 6 or FIG. The protruding portion 144 is formed in a portion between the through hole 142 and the cut portion 143 in the electric wire passage portion 141, and is a portion protruding on the surface opposite to the side through which the electric wire 9 passes.
　なお、ベース部１は凹凸をなす板状の部材であるので、電線結束部１４の突起部１４４は、中空の突起部である。即ち、電線結束部１４の突起部１４４は、電線９が通過する側から見れば窪みを形成している。 In addition, since the base part 1 is a plate-shaped member which makes an unevenness | corrugation, the projection part 144 of the electric wire binding part 14 is a hollow projection part. That is, the protrusion 144 of the wire binding portion 14 forms a recess when viewed from the side through which the wire 9 passes.
　図７と図１３とを比較すればわかるように、突起部１４４が存在することにより、結束ベルト８が、貫通孔１４２の縁部及び切れ込み部１４３の縁部において急峻に折れ曲がりにくい。即ち、結束ベルト８は、より円形に近い形で電線通過部１４１と電線９とを結束できる。図１３に示されるような電線結束部１４が、配線具１０に採用されることも考えられる。 As can be seen from a comparison between FIG. 7 and FIG. 13, the presence of the protrusion 144 makes it difficult for the binding belt 8 to be sharply bent at the edge of the through-hole 142 and the edge of the notch 143. That is, the binding belt 8 can bind the electric wire passage portion 141 and the electric wire 9 in a shape that is closer to a circle. It is also conceivable that the wire binding portion 14 as shown in FIG.
　＜コネクタ支持部＞
　次に、図８から図１０を参照しつつ、コネクタ支持部１５について説明する。図８は、配線具１０におけるコネクタ支持部１５の斜視図である。図９は、電線９の端部におけるコネクタ９１の部分の斜視図である。図１０は、コネクタ９１が固定されたコネクタ支持部１５の正断面図である。 <Connector support part>
Next, the connector support 15 will be described with reference to FIGS. FIG. 8 is a perspective view of the connector support 15 in the wiring tool 10. FIG. 9 is a perspective view of a portion of the connector 91 at the end of the electric wire 9. FIG. 10 is a front sectional view of the connector support 15 to which the connector 91 is fixed.
　ここで、コネクタ支持部１５について説明する前に、コネクタ支持部１５に固定されるコネクタ９１の構造について説明する。 Here, before describing the connector support 15, the structure of the connector 91 fixed to the connector support 15 will be described.
　図９に示されるように、電線９の端部のコネクタ９１には、クランプなどの他の部材と連結される連結部９２が形成されている。連結部９２は、連結される相手側部材の一部が嵌り込む隙間を形成する平行な一対のガイドレール部９２１と、一対のガイドレール部９２１に架け渡された架設部９２２とを有する。 As shown in FIG. 9, the connector 91 at the end of the electric wire 9 is formed with a connecting portion 92 that is connected to another member such as a clamp. The connecting portion 92 includes a pair of parallel guide rail portions 921 that form a gap into which a part of the mating member to be connected is fitted, and an erected portion 922 that spans the pair of guide rail portions 921.
　また、架設部９２２におけるコネクタ９１の本体の底面に対向する面には、コネクタ９１の本体側に向かって突出する突起部９２３が形成されている。 Further, a protrusion 923 that protrudes toward the main body side of the connector 91 is formed on the surface of the installation portion 922 that faces the bottom surface of the main body of the connector 91.
　一対のガイドレール部９２１は、コネクタ９１の外表面から突起し、平行に直線状に延びて形成された一対の平行な凸部を形成している。また、架設部９２２は、一対のガイドレール部９２１の間においてコネクタ９１の外表面に対して間隔を空けて形成された梁部を形成している。また、突起部９２３は、架設部９２２からコネクタ９１の外表面に向かって突起して形成された凸部を形成している。 The pair of guide rail portions 921 protrudes from the outer surface of the connector 91, and forms a pair of parallel convex portions formed in a straight line extending in parallel. Further, the erection part 922 forms a beam part formed between the pair of guide rail parts 921 so as to be spaced from the outer surface of the connector 91. Further, the protrusion 923 forms a protrusion formed by protruding from the installation part 922 toward the outer surface of the connector 91.
　図９に示されるコネクタ９１は、自動車に搭載されるワイヤハーネスにおいて広く用いられている。一般的には、連結部９２に対する相手側部材は、連結部９２における一対のガイドレール部９２１が形成する隙間に嵌り込む嵌入片を有する。また、その嵌入片には、その嵌入片が一対のガイドレール部９２１の隙間に嵌め入れられたときに、連結部９２の突起部９２３が嵌り込む孔が形成されている。嵌入片が一対のガイドレール部９２１の隙間に嵌め入れられることにより、連結部９２と相手側部材とは、連結した状態で保持される。 The connector 91 shown in FIG. 9 is widely used in wire harnesses mounted on automobiles. In general, the mating member for the connecting portion 92 has a fitting piece that fits into the gap formed by the pair of guide rail portions 921 in the connecting portion 92. In addition, the insertion piece is formed with a hole into which the protrusion 923 of the connecting portion 92 is fitted when the insertion piece is fitted into the gap between the pair of guide rail portions 921. When the fitting piece is fitted into the gap between the pair of guide rail portions 921, the connecting portion 92 and the counterpart member are held in a connected state.
　一方、図８に示されるように、本実施形態におけるコネクタ支持部１５には、一対の平行凹部１５１と、それら一対の平行凹部１５１の間の部分である中間板部１５２とが形成されている。 On the other hand, as shown in FIG. 8, the connector support portion 15 in the present embodiment is formed with a pair of parallel concave portions 151 and an intermediate plate portion 152 that is a portion between the pair of parallel concave portions 151. .
　コネクタ支持部１５において、一対の平行凹部１５１は、ベース部１における第一枠部１３の外縁から内側へ直線状に延びる平行な一対の溝を形成する部分である。より具体的には、第一枠部１３の外縁から内側へ直線状に延びて形成された底板部１５１１と、その底板部１５１１の両側方において底板部１５１１に連なって形成された２つの側壁部１５１２とにより構成されている。側壁部１５１２は、底板部１５１１の両側方において底板部１５１１から起立する段差を形成している。一対の平行凹部１５１が形成する一対の溝には、コネクタ９１の連結部９２における一対のガイドレール部９２１が嵌め入れられる。 In the connector support portion 15, the pair of parallel recesses 151 are portions that form a pair of parallel grooves extending linearly inward from the outer edge of the first frame portion 13 in the base portion 1. More specifically, a bottom plate portion 1511 formed linearly extending inward from the outer edge of the first frame portion 13, and two side wall portions formed continuously to the bottom plate portion 1511 on both sides of the bottom plate portion 1511. 1512. The side wall portion 1512 forms a step rising from the bottom plate portion 1511 on both sides of the bottom plate portion 1511. A pair of guide rail portions 921 in the connecting portion 92 of the connector 91 is fitted into a pair of grooves formed by the pair of parallel recesses 151.
　また、コネクタ支持部１５において、中間板部１５２は、一対の平行凹部１５１の間の板状の部分であり、コネクタ９１の本端部分の外表面と連結部９２の架設部９２２との間の隙間に挿入される部分である。本実施形態においては、中間板部１５２は、平板状である。 Further, in the connector support portion 15, the intermediate plate portion 152 is a plate-like portion between the pair of parallel recesses 151, and is between the outer surface of the main end portion of the connector 91 and the installation portion 922 of the connecting portion 92. It is the part that is inserted into the gap. In the present embodiment, the intermediate plate portion 152 has a flat plate shape.
　また、中間板部１５２には、中間板部１５２がコネクタ９１の本体部分の外表面と連結部９２の架設部９２２との間の隙間に挿入されたときに、架設部９２２に形成された突起部９２３が嵌り込む孔１５３が形成されている。 Further, the intermediate plate portion 152 has a protrusion formed on the installation portion 922 when the intermediate plate portion 152 is inserted into the gap between the outer surface of the main body portion of the connector 91 and the installation portion 922 of the connecting portion 92. A hole 153 into which the portion 923 is fitted is formed.
　図１０に示されるように、コネクタ９１がコネクタ支持部１５に固定された状態において、コネクタ９１の連結部９２における一対のガイドレール部９２１は、コネクタ支持部１５における一対の平行凹部１５１に嵌め入れられている。さらに、コネクタ支持部１５の中間板部１５２は、コネクタ９１の本体部分の外表面と連結部９２の架設部９２２との間の隙間に挿入されており、連結部９２の架設部９２２に形成された突起部９２３が、中間板部１５２に形成された孔１５３に嵌り込んでいる。 As shown in FIG. 10, in a state where the connector 91 is fixed to the connector support portion 15, the pair of guide rail portions 921 in the connecting portion 92 of the connector 91 is fitted into the pair of parallel recesses 151 in the connector support portion 15. It has been. Further, the intermediate plate portion 152 of the connector support portion 15 is inserted into a gap between the outer surface of the main body portion of the connector 91 and the erection portion 922 of the connection portion 92, and is formed in the erection portion 922 of the connection portion 92. The protruding portion 923 is fitted in the hole 153 formed in the intermediate plate portion 152.
　コネクタ支持部１５において、一対の平行凹部１５１は、一対の平行凹部１５１の溝の長手方向に対して直交する方向におけるコネクタ９１の動きを制限する。また、中間板部１５２は、コネクタ９１の本体部分の外表面と連結部９２の架設部９２２との間の隙間に挿入されることにより、一対の平行凹部１５１の溝の深さ方向におけるコネクタ９１の動きを制限する。さらに、中間板部１５２における孔１５３の縁部は、一対の平行凹部１５１の溝の長手方向におけるコネクタ９１の動きを制限する。 In the connector support portion 15, the pair of parallel recesses 151 restrict the movement of the connector 91 in the direction orthogonal to the longitudinal direction of the grooves of the pair of parallel recesses 151. Further, the intermediate plate portion 152 is inserted into a gap between the outer surface of the main body portion of the connector 91 and the erection portion 922 of the connecting portion 92, so that the connector 91 in the groove depth direction of the pair of parallel concave portions 151. Limit movement. Further, the edge portion of the hole 153 in the intermediate plate portion 152 restricts the movement of the connector 91 in the longitudinal direction of the grooves of the pair of parallel concave portions 151.
　また、本実施形態においては、中間板部１５２の両側における一対の平行凹部１５１各々との境界部分に、内側へ切れ込んだ切れ込み部１５４が形成されている。これにより、中間板部１５２における第一枠部１３の外縁側の端部は、片持ち梁状に張り出した庇部１５２１を形成している。 Further, in the present embodiment, a cut portion 154 cut inward is formed at a boundary portion between each of the pair of parallel recesses 151 on both sides of the intermediate plate portion 152. Thereby, the edge part of the outer edge side of the 1st frame part 13 in the intermediate | middle board part 152 forms the collar part 1521 which protruded in the shape of a cantilever.
　図９に示されるコネクタ９１の連結部９２においては、一対のガイドレール部９２１各々と架設部９２２との間に、一対の平行凹部１５１の側壁部１５１２の一部が入り込む隙間９２４が形成されている。この場合、コネクタ支持部１５において、切れ込み部１５４が形成されていることは必須ではない。 In the connecting portion 92 of the connector 91 shown in FIG. 9, a gap 924 into which a part of the side wall portion 1512 of the pair of parallel recesses 151 enters is formed between each of the pair of guide rail portions 921 and the installation portion 922. Yes. In this case, it is not essential that the notch 154 is formed in the connector support 15.
　本実施形態においては、中間板部１５２が、コネクタ９１の本体部分の外表面と連結部９２の架設部９２２との間の隙間により深く挿入されるように、中間板部１５２の両側に切れ込み部１５４が形成されている。これにより、中間板部１５２が、架設部９２２に対してより安定した状態で引っ掛かり、コネクタ９１がコネクタ支持部１５から外れにくくなる。 In the present embodiment, the intermediate plate portion 152 is cut into both sides of the intermediate plate portion 152 so that the intermediate plate portion 152 is inserted deeper into the gap between the outer surface of the main body portion of the connector 91 and the erection portion 922 of the connecting portion 92. 154 is formed. Accordingly, the intermediate plate portion 152 is hooked in a more stable state with respect to the installation portion 922, and the connector 91 is less likely to be detached from the connector support portion 15.
　しかしながら、コネクタ９１の連結部９２に隙間９２４が形成されていない場合、コネクタ支持部１５において、切れ込み部１５４が形成されていることが必要である。これにより、中間板部１５２をコネクタ９１の本体部分の外表面と連結部９２の架設部９２２との間の隙間に挿入することが可能となる。 However, when the gap 924 is not formed in the connecting portion 92 of the connector 91, it is necessary that the notch portion 154 is formed in the connector support portion 15. Thereby, the intermediate plate portion 152 can be inserted into the gap between the outer surface of the main body portion of the connector 91 and the erection portion 922 of the connecting portion 92.
　また、図９に示されるコネクタ９１の連結部９２においては、中間板部１５２よりも内側において一対の平行凹部１５１が形成する一対の溝を繋ぐ溝を形成する部分である内側凹部１５５がさらに形成されている。この内側凹部１５５は、凹凸をなす板状の部分であるコネクタ支持部１５の剛性を高める効果、特に、コネクタ支持部１５をねじるように作用する外力に対する剛性を高める効果を発揮する。 Further, in the connecting portion 92 of the connector 91 shown in FIG. 9, an inner concave portion 155 that further forms a groove connecting the pair of grooves formed by the pair of parallel concave portions 151 inside the intermediate plate portion 152 is further formed. Has been. The inner concave portion 155 exhibits an effect of increasing the rigidity of the connector support portion 15 which is a plate-like portion having irregularities, and in particular, an effect of increasing the rigidity against an external force acting to twist the connector support portion 15.
　以上に示したように、コネクタ９１は、コネクタ支持部１５によって支持され、第一枠部１３の一部に固定される。即ち、コネクタ支持部１５は、電線９の端部に取り付けられたコネクタ９１の外表面に形成された連結部９２と係り合ってコネクタ９１を支持する。これにより、電線９の端部のコネクタ９１は、ごく簡易な作業により第一枠部１３における予め定められた位置に固定される。 As described above, the connector 91 is supported by the connector support portion 15 and is fixed to a part of the first frame portion 13. That is, the connector support portion 15 supports the connector 91 by engaging with a connecting portion 92 formed on the outer surface of the connector 91 attached to the end portion of the electric wire 9. Thereby, the connector 91 at the end of the electric wire 9 is fixed at a predetermined position in the first frame portion 13 by a very simple operation.
　＜他の実施例に係るコネクタ支持部＞
　次に、図１１を参照しつつ、配線具１０に適用可能な他の実施例に係るコネクタ支持部１７について説明する。図１１は、コネクタ支持部１７及びコネクタ９１の斜視図である。 <Connector support according to another embodiment>
Next, the connector support part 17 which concerns on the other Example applicable to the wiring tool 10 is demonstrated, referring FIG. FIG. 11 is a perspective view of the connector support portion 17 and the connector 91.
　図１１に示されるように、コネクタ支持部１７は、コネクタ９１の連結部９２における一対のガイドレール部９２１の隙間に嵌り込む嵌入片１７１を有する。嵌入片１７１は、第一枠部１３の縁部に形成された一対の切り込みの間の部分である。また、嵌入片１７１には、嵌入片１７１が一対のガイドレール部９２１の隙間に嵌め入れられたときに、連結部９２の突起部９２３が嵌り込む孔１７２が形成されている。 As shown in FIG. 11, the connector support portion 17 has a fitting piece 171 that fits into the gap between the pair of guide rail portions 921 in the connecting portion 92 of the connector 91. The fitting piece 171 is a portion between a pair of cuts formed at the edge of the first frame portion 13. The fitting piece 171 has a hole 172 into which the projection 923 of the connecting portion 92 is fitted when the fitting piece 171 is fitted into the gap between the pair of guide rail portions 921.
　嵌入片１７１が連結部９２における一対のガイドレール部９２１の隙間に嵌め入れられることにより、コネクタ９１は、コネクタ支持部１７に固定される。即ち、コネクタ支持部１７は、電線９の端部に取り付けられたコネクタ９１に形成された連結部９２と係り合ってコネクタ９１を支持する。図１１に示されるようなコネクタ支持部１７が、配線具１０に適用されてもよい。 The connector 91 is fixed to the connector support portion 17 by inserting the insertion piece 171 into the gap between the pair of guide rail portions 921 in the connecting portion 92. In other words, the connector support portion 17 supports the connector 91 by engaging with the connecting portion 92 formed on the connector 91 attached to the end portion of the electric wire 9. A connector support portion 17 as shown in FIG. 11 may be applied to the wiring tool 10.
　ワイヤハーネス１００において、電線９は、配線具１０を構成するベース部１及びカバー部２の間に挟み込まれる。さらに、板状のベース部１において内側の配線部１１から外側の第一枠部１３に亘って配置された電線９は、第一枠部１３における予め定められた位置に設けられた電線結束部１４又はコネクタ支持部１５で固定される。 In the wire harness 100, the electric wire 9 is sandwiched between the base portion 1 and the cover portion 2 constituting the wiring tool 10. Further, the electric wire 9 arranged from the inner wiring portion 11 to the outer first frame portion 13 in the plate-like base portion 1 is an electric wire binding portion provided at a predetermined position in the first frame portion 13. 14 or the connector support 15.
　従って、配線具１０が取り付けられた電線９において、電線結束部１４又はコネクタ支持部１５で固定された部分は一定の位置に保持され、さらに、電線結束部１４又はコネクタ支持部１５で固定された部分から外側に位置する部分の長さは一定の長さで保持される。即ち、電線９の端部が接続相手に対して過不足なく届くように、電線９の形状が配線具１０によって保持される。また、電線９は、ベース部１及びカバー部２によって保護される。 Therefore, in the electric wire 9 to which the wiring tool 10 is attached, the portion fixed by the electric wire binding portion 14 or the connector support portion 15 is held at a fixed position, and further fixed by the electric wire binding portion 14 or the connector support portion 15. The length of the part located outside the part is maintained at a constant length. That is, the shape of the electric wire 9 is held by the wiring tool 10 so that the end of the electric wire 9 can reach the connection partner without excess or deficiency. Further, the electric wire 9 is protected by the base portion 1 and the cover portion 2.
　一方、配線具１０が取り付けられた電線９において、配線部１１に配置された部分、即ち、ベース部１の第一枠部１３に至るまでの途中の中間部分は、ベース部１の内側の領域を占める配線部１１とカバー部２の内側の領域を占める対向壁部２１との間の仕切の無い配線空間９０内に収容される。 On the other hand, in the electric wire 9 to which the wiring tool 10 is attached, a portion arranged in the wiring portion 11, that is, an intermediate portion on the way to the first frame portion 13 of the base portion 1 is an area inside the base portion 1. Is housed in a wiring space 90 without a partition between the wiring portion 11 occupying the area and the opposing wall portion 21 occupying the area inside the cover portion 2.
　従って、電線９をベース部１の配線部１１に配線する作業において、配線部１１内の任意の経路での配線が許容され、電線９が配線部１１から浮き上がっていても、カバー部２をベース部１に重ねて押し付けるだけで、電線９は配線部１１と対向壁部２１との間の配線空間９０に収容される。即ち、配線部１１から浮き上がる電線９を配線部１１に対して押さえ込みつつ電線９を配線するという煩雑な作業は不要である。即ち、ワイヤハーネス１００が採用されることにより、配線具１０を電線９に取り付けるための工数を簡素化できる。 Therefore, in the operation of wiring the electric wire 9 to the wiring portion 11 of the base portion 1, wiring in an arbitrary path within the wiring portion 11 is allowed, and the cover portion 2 is used as the base even if the electric wire 9 is lifted from the wiring portion 11. The electric wire 9 is accommodated in the wiring space 90 between the wiring part 11 and the opposing wall part 21 only by pressing on the part 1. That is, the complicated operation of wiring the electric wire 9 while pressing the electric wire 9 floating from the wiring portion 11 against the wiring portion 11 is unnecessary. That is, by employing the wire harness 100, the number of steps for attaching the wiring tool 10 to the electric wire 9 can be simplified.
　＜電線結束部の効果＞
　配線具１０の電線結束部１４において、貫通孔１４２の縁部は、振動などによって電線９に対する結束ベルト８の位置が移動し、結束ベルト８が第一枠部１３から外れることを防止する。そのため、電線９は、電線結束部１４において安定的に強固に固定される。また、電線９における結束ベルト８で固定された部分から末端側の部分の長さが、予め定められた長さで保持される。さらに、結束ベルト８の先端を貫通孔に挿入する作業の回数が１回で済み、２つの貫通孔に結束ベルト８を通す場合に比べ、結束作業の工数が軽減される。 <Effect of the cable binding part>
In the electric wire binding portion 14 of the wiring tool 10, the edge of the through hole 142 prevents the binding belt 8 from moving from the first frame portion 13 due to movement of the position of the binding belt 8 relative to the electric wire 9 due to vibration or the like. Therefore, the electric wire 9 is stably and firmly fixed at the electric wire binding portion 14. Further, the length of the portion of the electric wire 9 from the portion fixed by the binding belt 8 to the end side is held at a predetermined length. Furthermore, the number of operations for inserting the tip of the binding belt 8 into the through hole is one, and the man-hour for the binding operation is reduced as compared with the case where the binding belt 8 is passed through the two through holes.
　また、図６及び図７に示される電線結束部１４において、結束ベルト８は、電線通過部１４１の両側において、貫通孔１４２の縁部と切れ込み部１４３の段差１４３３の部分とに引っ掛かる。これにより、結束ベルト８の位置ずれが、より確実に防止される。 6 and 7, the binding belt 8 is caught by the edge of the through-hole 142 and the step 1433 of the notch 143 on both sides of the wire passing portion 141. Thereby, position shift of the binding belt 8 is prevented more reliably.
　また、図１３に示される電線結束部１４においては、電線通過部１４１における電線９が通過する側の反対側の面において突出する突起部１４４が形成されている。これにより、結束ベルト８は、貫通孔１４２の縁部及び切れ込み部１４３の縁部において急峻に折れ曲がりにくく、より円形に近い形で電線通過部１４１と電線９とを結束できる。その結果、結束ベルト８によって電線９と電線通過部１４１とをより強固に結束することが可能となる。 Moreover, in the electric wire binding part 14 shown by FIG. 13, the protrusion part 144 which protrudes in the surface on the opposite side to the side through which the electric wire 9 passes in the electric wire passage part 141 is formed. As a result, the binding belt 8 is less likely to be sharply bent at the edge of the through hole 142 and the edge of the cut-out portion 143, and can bind the wire passing portion 141 and the wire 9 in a more circular shape. As a result, it becomes possible to bind the electric wire 9 and the electric wire passage portion 141 more firmly by the bundling belt 8.
　＜その他＞
　以上に示された実施形態においては、ベース部１とカバー部２とは、接続部３を介して繋がって一体に形成されている。しかしながら、ベース部１とカバー部２とが別部材で構成されることも考えられる。 <Others>
In the embodiment shown above, the base portion 1 and the cover portion 2 are integrally connected to each other via the connection portion 3. However, it is also conceivable that the base part 1 and the cover part 2 are constituted by different members.
　また、配線具１０のベース部１において、凸部１１１が形成されていない平坦な配線部１１が採用されることも考えられる。また、ベース部１の配線部１１に、格子状又は網目状に連なる凸部又は溝が形成されることも考えられる。そのような凸部又は溝も、配線部１１の剛性を高める効果を奏する。 It is also conceivable that a flat wiring portion 11 in which the convex portion 111 is not formed is employed in the base portion 1 of the wiring tool 10. It is also conceivable that convex portions or grooves that are continuous in a lattice shape or a mesh shape are formed in the wiring portion 11 of the base portion 1. Such a protrusion or groove also has an effect of increasing the rigidity of the wiring portion 11.
　また、ベース部１及びカバー部２が、樹脂の射出成形により得られる部材であることも考えられる。但し、配線具１０は、上下方向（一次元方向）においてのみ凹凸をなす板状に成形された部材であり、板状の樹脂部材に対する真空成形によって容易に得られる部材である。従って、製造工数及び製造コストの面において、配線具１０は、平板状の部材の真空成形により得られる部材であることが望ましい。 It is also conceivable that the base 1 and the cover 2 are members obtained by resin injection molding. However, the wiring tool 10 is a member formed into a plate shape having irregularities only in the vertical direction (one-dimensional direction), and can be easily obtained by vacuum forming a plate-shaped resin member. Therefore, in terms of manufacturing man-hours and manufacturing costs, the wiring tool 10 is desirably a member obtained by vacuum forming a flat member.
