Description

ワイヤハーネス用固定具および当該ワイヤハーネス用固定具を備えたワイヤハーネスWire harness fixture and wire harness provided with the wire harness fixture
　本発明は、パネルに配索される電線のぐらつきと移動を防止するワイヤハーネス用固定具および当該ワイヤハーネス用固定具を備えたワイヤハーネスに関する。 The present invention relates to a wire harness fixture that prevents wobbling and movement of electric wires routed in a panel, and a wire harness including the wire harness fixture.
　自動車等には、種々の電子機器と電装品とが搭載されている。前記電子機器や電装品には、バッテリなどの電源等からの電力や制御装置からの制御信号などを伝えるワイヤハーネスが電気的に接続されている。 Various electronic devices and electrical components are mounted on automobiles. A wire harness for transmitting electric power from a power source such as a battery or a control signal from a control device is electrically connected to the electronic device or the electrical component.
　ワイヤハーネスは、自動車等の車体を構成するパネルに配索されている。ワイヤハーネスは、電源等や制御装置などに電気的に接続するコネクタやターミナルなどが端末に設けられた電線と、前記電線に取り付けられ前記パネルの取付孔に係止されるワイヤハーネス用固定具と、を備えている（例えば、特許文献１参照。）。特許文献１に記載のワイヤハーネス用固定具は、前記電線に対して移動可能に形成されている。 The wire harness is routed on a panel that forms the body of an automobile or the like. The wire harness includes an electric wire in which a connector or a terminal that is electrically connected to a power source or a control device is provided at the terminal, and a wire harness fixing tool that is attached to the electric wire and locked in the mounting hole of the panel.

特開２００２－３１５１６４号公報JP 2002-315164 A
　しかしながら、特許文献１に記載のワイヤハーネス用固定具は、当該ワイヤハーネス用固定具の電線と、前記パネルに配索される複数本の電線を束ねた電線束とが粘着テープ等で捲回されて、前記電線束に前記ワイヤハーネス用固定具が取り付けられた際に、前記ワイヤハーネス用固定具自体は前記粘着テープに捲回されないため、前記ワイヤハーネス用固定具上で前記電線束がぐらつくという問題があった。 However, in the wire harness fixture described in Patent Document 1, the wire of the wire harness fixture and the wire bundle obtained by bundling a plurality of wires routed on the panel are wound with an adhesive tape or the like. When the wire harness fixture is attached to the wire bundle, the wire harness fixture itself is not wound around the adhesive tape, and therefore the wire bundle is wobbled on the wire harness fixture. There was a problem.
　また、特許文献１に記載のワイヤハーネス用固定具は、電線に対して移動可能に形成されているため、前記ワイヤハーネス用固定具上で前記電線束が当該電線束の軸方向に移動したり、前記電線束の外周面方向に移動したりする問題があった。 In addition, since the wire harness fixture described in Patent Document 1 is formed to be movable with respect to the electric wire, the wire bundle moves in the axial direction of the wire bundle on the wire harness fixture. There has been a problem of moving in the direction of the outer peripheral surface of the wire bundle.
　本発明は、かかる問題を解決することを目的としている。即ち、本発明は、パネルに配索される電線のぐらつきと移動を防止するワイヤハーネス用固定具および当該ワイヤハーネス用固定具を備えたワイヤハーネスを提供することを目的とする。 The present invention aims to solve such a problem.

It is the fixing tool for wire harnesses characterized by the above-mentioned.
　請求項２に記載された発明は、前記延長部が、平板状に形成されていることを特徴とする請求項１に記載のワイヤハーネス用固定具である。 The invention described in claim 2 is the wire harness fixture according to claim 1, wherein the extension is formed in a flat plate shape.
　請求項３に記載された発明は、パネルに配索される複数本の電線が束ねられた電線束と、請求項１又は請求項２に記載のワイヤハーネス用固定具と、を備えていることを特徴とするワイヤハーネスである。 The invention described in claim 3 is provided with an electric wire bundle in which a plurality of electric wires routed on the panel are bundled, and the wire harness fixing tool according to claim 1 or claim 2. It is a wire harness characterized by these.
　請求項１に記載された発明によれば、ワイヤハーネス用固定具は、電線の外周面を被覆する電線被覆部が、延長部と固定部とに連続して設けられているため、固定部に前記電線が確実に固定される。さらに、前記延長部と電線束とを粘着テープ等によって捲回することによって、ワイヤハーネス用固定具に前記電線束が確実に固定される。従って、ワイヤハーネス用固定具は、ぐらついたり移動したりすることなく電線束をパネル上に固定することができる。 According to the invention described in claim 1, the wire harness fixing tool has the wire covering portion that covers the outer peripheral surface of the electric wire continuously provided on the extension portion and the fixing portion. The electric wire is securely fixed. Furthermore, the said wire bundle is reliably fixed to the fixture for wire harnesses by winding the said extension part and a wire bundle with an adhesive tape etc. FIG. Accordingly, the wire harness fixture can fix the wire bundle on the panel without wobbling or moving.
　請求項２に記載された発明によれば、ワイヤハーネス用固定具は、延長部が平板状に形成されているため、粘着テープ等が延長部に粘着される粘着性が向上すると共に、電線束に対して前記延長部の安定性が向上する。このため、ワイヤハーネス用固定具は、より強固に安定して電線束をパネル上に固定することができる。 According to the invention described in claim 2, since the wire harness fixture has the extension portion formed in a flat plate shape, the adhesiveness of the adhesive tape or the like being adhered to the extension portion is improved, and the wire bundle In contrast, the stability of the extension is improved.

　前記ワイヤハーネス用テープ９によって前記ワイヤハーネス用固定具２Ａが前記電線束５に組み付けられて、図６に示すように、ワイヤハーネス１Ａが形成される。前記電線束５の電線８と、前記ワイヤハーネス用固定具２Ａの電線１１とは、それぞれの端末に図示しないコネクタ等が設けられる。また、ワイヤハーネス１Ａには、チューブやプロテクタ等の外装部品が設けられる。 The wire harness fixing tool 2A is assembled to the wire bundle 5 by the wire harness tape 9, and the wire harness 1A is formed as shown in FIG. The electric wires 8 of the electric wire bundle 5 and the electric wires 11 of the wire harness fixture 2A are provided with connectors or the like (not shown) at respective terminals. Moreover, exterior components, such as a tube and a protector, are provided in the wire harness 1A.
　コネクタや外装部品等が設けられたワイヤハーネス１Ａは、前記布線板から取り外され、自動車等を構成するパネルに布線される。前記パネル上に布線されたワイヤハーネス１Ａは、前記ワイヤハーネス用固定具２Ａが取付孔に押し込まれる。 The wire harness 1A provided with connectors, exterior parts and the like is removed from the wiring board and wired to a panel constituting an automobile or the like. In the wire harness 1A wired on the panel, the wire harness fixture 2A is pushed into the mounting hole.
　取付孔に押し込まれたワイヤハーネス用固定具２Ａは、一対の係止部１７が前記取付孔内に挿通され、係止片２２のそれぞれの自由端が互いに近接する方向に弾性変形される。 The wire harness fixture 2A pushed into the mounting hole is elastically deformed in a direction in which the pair of locking portions 17 are inserted into the mounting holes and the free ends of the locking pieces 22 are close to each other.
　前記係止片２２のそれぞれの自由端が前記取付孔の周縁部に到達されると、前記係止片２２のそれぞれの自由端が互いに離間する方向に弾性回復力によって変位され、前記それぞれの自由端に設けられた係止段部が前記周縁部に係止される。このとき、押圧部２３の縁端が前記パネルの表面に当接され、当該パネルが前記押圧部２３の弾性力で押圧される。このため、前記係止片２２の係止力が向上されて、前記一対の係止部１７が取付孔に確実に安定して係止される。そして、ワイヤハーネス１Ａがパネルに固定される。 When each free end of the locking piece 22 reaches the peripheral edge of the mounting hole, each free end of the locking piece 22 is displaced by an elastic recovery force in a direction away from each other. A locking step provided at the end is locked to the peripheral edge. At this time, the edge of the pressing part 23 is brought into contact with the surface of the panel, and the panel is pressed by the elastic force of the pressing part 23. For this reason, the locking force of the locking piece 22 is improved, and the pair of locking portions 17 are reliably and stably locked in the mounting holes. Then, the wire harness 1A is fixed to the panel.
　本実施形態によれば、ワイヤハーネス用固定具２Ａは、一対の固定部１２から延長されたそれぞれの延長部１５と電線束５とがワイヤハーネス用テープ９で捲回されて電線束５に組み付けられるため、当該電線束５をパネル上にぐらついたり移動したりすることなく確実かつ十分に固定することができる。 According to the present embodiment, the wire harness fixture 2 </ b> A is assembled to the wire bundle 5 by winding each of the extended portions 15 and the wire bundle 5 extended from the pair of fixed portions 12 with the wire harness tape 9. Therefore, the wire bundle 5 can be surely and sufficiently fixed without wobbling or moving on the panel.
　また、ワイヤハーネス１Ａは、前述したワイヤハーネス用固定具２Ａを備えているため、前記パネルに配索される前記電線束５のぐらつきと移動とを確実に防止することができる。 Moreover, since the wire harness 1A includes the wire harness fixture 2A described above, the wire bundle 5 routed on the panel can be reliably prevented from wobbling and moving.
　また、ワイヤハーネス１Ａは、前述したワイヤハーネス用固定具２Ａを備えているため、係止部１７が前記パネルの取付孔に係止可能となる位置に配される。このため、係止部１７の位置合わせ作業が容易となり、ワイヤハーネス１Ａの組立作業の作業効率と、パネルへの取付作業の作業効率とが向上する。 Moreover, since the wire harness 1A includes the wire harness fixture 2A described above, the locking portion 17 is disposed at a position where the locking portion 17 can be locked in the mounting hole of the panel. For this reason, the positioning operation of the locking portion 17 is facilitated, and the work efficiency of the assembly work of the wire harness 1A and the work efficiency of the work of attaching to the panel are improved.
　なお、前述した実施形態は本発明の代表的な形態を示したに過ぎず、本発明は、実施形態に限定されるものではない。即ち、本発明の骨子を逸脱しない範囲で種々変形して実施することができる。 It should be noted that the above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments. That is, various modifications can be made without departing from the scope of the present invention.
　本発明にかかるワイヤハーネス用固定具は、自動車等の車体を構成するパネルの取付孔にワイヤハーネスを固定するための固定具として利用でき、本発明にかかるワイヤハーネス用固定具を備えたワイヤハーネスは、自動車等の車体を構成するパネルの取付孔に固定して配索することのできるワイヤハーネスとして利用できる。 The wire harness fixture according to the present invention can be used as a fixture for fixing a wire harness to a mounting hole of a panel constituting a vehicle body such as an automobile, and the wire harness provided with the wire harness fixture according to the present invention. Can be used as a wire harness that can be fixed and routed in a mounting hole of a panel constituting a vehicle body such as an automobile.
