Description

【0001】
【発明の属する技術分野】
本発明はワイヤハーネス等の電線を保護する電線用プロテクタに関する。
【0002】
【従来の技術】
実開平2−83618号公報には図3に示すような電線プロテクタが記載されている。
図3において、11は円筒体であり、その一側に切り割12を有し、切り割12によって分離された円筒体11には両側縁13および13′より立上って係止片14および14′が設けられている。15は前記係止片14および14′と係合する係止具である。
【0003】
【発明が解決しようとする課題】
前述したように、従来の電線用プロテクタは円筒体の切り割の両側縁から立上げて係止片を設け、該係止片に係止具を係合させるものであった。
このため、構造が複雑であるとともに、円筒体に収容される電線束が小さい場合は両側縁13および13′を押圧してその間隔を狭くして係止片14および14′を係止具15と係合させることができるが、電線束が太くなると切り割12の幅を狭くすることができず、係止具15の先端を係止片14および14′に係合させて長手方向に押込むようにしなければならず、作業性が非常に悪くなる。本発明は簡単な構造で容易に電線を収容することができる電線プロテクタを提供することを課題とする。
【0004】
【課題を解決するための手段】
前述した課題を解決するために、請求項1の発明においては、電線束を収容する可撓性の内筒体と、この内筒体を収容する可撓性の外筒体とから成り、前記内筒体は周壁の一側に長手方向に沿う切り割を有すると共に他側に該切り割と対向して長手方向に沿う係止突条を有し前記外筒体は周壁の一側に前記係止突条と係合する長手方向に沿う切り割を有することを特徴とする。
内筒体の長手方向に切り割を設け、該切り割と対向して外部に向って突出した係止突条を設け、外筒体の長手方向に設けた切り割を広げて内筒体に外装するようにしたので、構造が簡単で容易に電線を収容することができる。
さらに、前記外筒体が、前記内筒体に収容される電線束の径の大小に応じて適合するように、外筒体の内径が内筒体の外径と等しいもの、およびこれより大きいものと小さいものから選ばれる。
この構成により、内径の異なる複数種類の外筒体を用意し、電線束の太さに合った径の外筒体を使用するようにしたので、種々のワイヤハーネスに対して内筒体を共用することができ、コストを低下させることができる。
【0005】
請求項2の発明においては、前記内筒体の厚さが前記切り割に向けて次第に薄く形成されている。従って、切り割部分の開放を容易に行うことができ、むりな力を加えずに電線を容易に収納することができる。
【0007】
請求項の発明は、前記内筒体および外筒体がコルゲートチューブであり、
また、請求項の発明は、前記係止突条が複数個に分割形成されているものである。
請求項の発明では、内筒体と外筒体が共にコルゲートチューブでできているので、収容したワイヤハーネスを所望の方向に曲げて配設固定することができ、さらに請求項の発明のように係止突条を分割形成することにより上記曲げ作業が一層容易になる。
【0008】
【発明の実施の形態】
本発明の実施の形態の一例を図1を参照して説明する。図1(A)は本発明の実施例の分離状態の斜視図、(B)はその使用状態の断面図である。
図1において、1は電線3を収容する断面が円形の内筒体、2は内筒体1を収納する外筒体で、いずれもポリ塩化ビニルやポリエチレンなどの可撓性の材料でできている。
【0009】
内筒体1には、周壁の一側に長手方向に沿って外部に向って突出した断面がT字状の係止突条1aが形成され、他側に係止突条1aと対向して長手方向に沿う切り割1bが設けられている。
また、外筒体2には、係止突条1aに対応してこれに係合する切り割2aが長手方向に設けられている。
【0010】
上記構成において、プロテクタに電線を収納するには、先ず内筒体1の切り割1bを開いて電線3を収納する。その後、外筒体2の切り割2aを開き、係止突条1aの反対側から内筒体1に被せるか、または係止突条1aに切り割2aをスライドさせながら外筒体2を外挿することにより、外筒体2の中に内筒体1を収納する。
【0011】
このようにして収納された電線3は、プロテクタが曲げられても、外筒体2は内筒体1に設けられた係止突条1aによって係止されているため、内筒体1を放出することがなく、また、内筒体1の切り割1bは外部より外筒体2で覆われているため電線3が放出されることはない。
【0012】
また、図2は本発明の第2の実施例を示しており、(A)は内筒体の断面図、(B)および(C)は電線束が太い場合と細い場合の実装の断面図である。
第2の実施例では、図2(A)に示されるように、内筒体1′の円筒部分の厚さを切り割1bに向かうにしたがって薄く形成してある。また、前記外筒体2の内径を内筒体1′の外径に対して大きいもの、小さいものおよび同じもの等、複数の種類のものを用意する。
このように構成されたプロテクタに、前述した方法により電線束を内筒体1′に収納し、その後、電線束を収納した内筒体1′の径に見合う径の外筒体2に内筒体1を収納する。
【0013】
図2(B)は電線束が太い場合で、この場合には内筒体1′の切り割1bは大きく広がった状態とはなるが、その外径に見合った外筒体2′によって電線が放出されることはない。
【0014】
また、電線束が細い場合は、図2(C)に示されるように、内筒体1′の切り割1bの両側縁が重なった状態となり径の小さい外筒体2″の中に収納される。
【0015】
このように、内筒体1′の厚さを切り割1bに向かうに従って薄くし、外筒体2は径の異なる種々なものを用意することによって、電線束に見合った太さのプロテクタにすることができ、その場合内筒体は共通に使用することができ、コストを低減することができる。
【0016】
以上は内筒体1、外筒体2などが通常の円筒状の直管で形成されている場合について説明したが、ワイヤハーネスを車両の内部構造に合わせて自由に曲げられるように、コルゲートチューブ(図示省略)で形成することができ、この場合には内筒体1の前記係止突条1aに適宜間隔で切り込みを設けて複数の係止突条1aとして分割形成することが好ましい。
【0017】
【発明の効果】
以上説明したように、本発明によれば次の効果が得られる。
内筒体の長手方向に切り割を設け、該切り割と対向して外部に向って突出した係止突条を設け、外筒体の長手方向に設けた切り割を広げて内筒体に外装するようにしたので、構造が簡単で容易に電線を収容することができる(請求項1)。
内筒体の厚さを切り割に向かうに従って薄くするようにしたので、切り割部分の開放を容易に行うことができ、むりな力を加えずに電線を容易に収納することができる(請求項2)。
また、内径の異なる複数種類の外筒体を用意し、電線束の太さに合った径の外筒体を使用するようにしたので、種々のワイヤハーネスに対して内筒体を共用することができ、コスト低減を図ることができる(請求項3)。
さらに、内筒体と外筒体を共にコルゲートチューブとすることにより、収容したワイヤハーネスを所望の方向に曲げて配設固定することができ(請求項4)、係止突条を分割形成することにより上記曲げ作業を一層容易にすることができる(請求項5)。

BACKGROUND OF THE INVENTION
The present invention relates to a wire protector for protecting a wire such as a wire harness.
[0002]
[Prior art]
Japanese Utility Model Laid-Open No. 2-83618 discloses a wire protector as shown in FIG.
In FIG. 3, reference numeral 11 denotes a cylindrical body having a slit 12 on one side thereof. The cylindrical body 11 separated by the slit 12 rises from both side edges 13 and 13 ′ to the locking pieces 14 and 14 'is provided. Reference numeral 15 denotes a locking tool that engages with the locking pieces 14 and 14 '.

[Problems to be solved by the invention]
As described above, the conventional wire protector is provided with the locking pieces raised from the both side edges of the cylindrical cut, and the locking tools are engaged with the locking pieces.
For this reason, the structure is complicated, and when the wire bundle accommodated in the cylindrical body is small, both side edges 13 and 13 'are pressed to narrow the distance between them and the locking pieces 14 and 14' are locked to the locking tool 15. However, when the wire bundle becomes thick, the width of the slit 12 cannot be reduced, and the front end of the locking tool 15 is engaged with the locking pieces 14 and 14 ′ and pushed in the longitudinal direction. Workability becomes very poor. An object of the present invention is to provide an electric wire protector that can easily accommodate an electric wire with a simple structure.
[0004]
[Means for Solving the Problems]
In order to solve the above-described problem, in the invention of claim 1, the invention comprises a flexible inner cylinder that accommodates a wire bundle and a flexible outer cylinder that accommodates the inner cylinder. The inner cylinder has a slit along the longitudinal direction on one side of the peripheral wall, and has a locking protrusion along the longitudinal direction opposite to the slit on the other side, and the outer cylinder is on the one side of the peripheral wall. It has a cut along the longitudinal direction that engages with the locking protrusion.
A slit is provided in the longitudinal direction of the inner cylinder, a locking ridge projecting outward is provided opposite to the slit, and the slit provided in the longitudinal direction of the outer cylinder is widened to the inner cylinder. Since the exterior is provided, the structure is simple and the electric wire can be accommodated easily.
Further, the outer cylinder has an inner diameter equal to or larger than the outer diameter of the inner cylinder so that the outer cylinder fits in accordance with the diameter of the wire bundle accommodated in the inner cylinder. It is chosen from the small one.
With this configuration, multiple types of outer cylinders with different inner diameters are prepared, and an outer cylinder with a diameter that matches the thickness of the wire bundle is used, so the inner cylinder is shared with various wire harnesses. Can reduce costs.
[0005]
In the invention of claim 2, the thickness of the inner cylinder is gradually made thinner toward the cut. Therefore, the cut portion can be easily opened, and the electric wire can be easily stored without applying an excessive force.
[0007]
In the invention of claim 3, the inner cylinder and the outer cylinder are corrugated tubes,
According to a fourth aspect of the present invention, the locking protrusion is divided into a plurality of parts.
In the invention of claim 3, since the inner cylinder and the outer cylinder member is made together with the corrugated tube, an accommodation to the wire harness is bent in the desired direction can be arranged fixed, further in the fourth aspect of the present invention Thus, the above-described bending operation is further facilitated by dividing and forming the locking protrusions.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
An example of the embodiment of the present invention will be described with reference to FIG. FIG. 1A is a perspective view of a separated state of an embodiment of the present invention, and FIG.
In FIG. 1, reference numeral 1 denotes an inner cylinder having a circular cross section for accommodating an electric wire 3, and 2 denotes an outer cylinder for accommodating an inner cylinder 1, both of which are made of a flexible material such as polyvinyl chloride or polyethylene. Yes.
[0009]
The inner cylindrical body 1 is formed with a locking ridge 1a having a T-shaped cross section projecting outward along the longitudinal direction on one side of the peripheral wall and facing the locking ridge 1a on the other side. A slit 1b is provided along the longitudinal direction.
Further, the outer cylindrical body 2 is provided with a slit 2a in the longitudinal direction that engages with the locking protrusion 1a.
[0010]
In the said structure, in order to accommodate an electric wire in a protector, the cut 1b of the inner cylinder 1 is opened first, and the electric wire 3 is accommodated. Thereafter, the slit 2a of the outer cylinder 2 is opened, and the inner cylinder 1 is covered from the opposite side of the locking ridge 1a, or the outer cylinder 2 is removed while sliding the slit 2a on the locking ridge 1a. By inserting, the inner cylinder 1 is accommodated in the outer cylinder 2.
[0011]
Even if the protector is bent, the outer cylindrical body 2 is locked by the locking protrusion 1a provided on the inner cylindrical body 1 so that the inner cylindrical body 1 is released. Moreover, since the cut 1b of the inner cylinder 1 is covered with the outer cylinder 2 from the outside, the electric wire 3 is not discharged.
[0012]
FIG. 2 shows a second embodiment of the present invention, where (A) is a cross-sectional view of the inner cylinder, and (B) and (C) are cross-sectional views of mounting when the wire bundle is thick and thin. It is.
In the second embodiment, as shown in FIG. 2 (A), the thickness of the cylindrical portion of the inner cylindrical body 1 'is formed thinner toward the cut 1b. Also, a plurality of types such as those having an inner diameter larger than the outer diameter of the inner cylinder 1 ', a smaller one, and the same are prepared.
In the protector thus configured, the wire bundle is accommodated in the inner cylinder 1 ′ by the method described above, and then the inner cylinder is formed in the outer cylinder 2 having a diameter corresponding to the diameter of the inner cylinder 1 ′ containing the wire bundle. The body 1 is stored.
[0013]
FIG. 2B shows a case where the bundle of electric wires is thick. In this case, the cut 1b of the inner cylinder 1 ′ is greatly expanded, but the outer cylinder 2 ′ commensurate with the outer diameter of the electric wire It will not be released.
[0014]
When the wire bundle is thin, as shown in FIG. 2 (C), both side edges of the cut 1b of the inner cylinder 1 'are overlapped and stored in the outer cylinder 2''having a small diameter. The
[0015]
In this way, the thickness of the inner cylinder 1 ′ is reduced toward the cut 1b, and the outer cylinder 2 is prepared with various diameters so that the protector has a thickness suitable for the wire bundle. In this case, the inner cylinder can be used in common, and the cost can be reduced.
[0016]
The above describes the case where the inner cylinder 1 and the outer cylinder 2 are formed of a normal cylindrical straight pipe. However, the corrugated tube can be freely bent so that the wire harness can be freely bent according to the internal structure of the vehicle. In this case, it is preferable that the locking protrusions 1a of the inner cylindrical body 1 are provided with cuts at appropriate intervals and divided into a plurality of locking protrusions 1a.
[0017]
【The invention's effect】
As described above, according to the present invention, the following effects can be obtained.
A slit is provided in the longitudinal direction of the inner cylinder, a locking ridge projecting outward is provided opposite to the slit, and the slit provided in the longitudinal direction of the outer cylinder is widened to the inner cylinder. Since the outer packaging is used, the structure is simple and the electric wire can be accommodated easily (claim 1).
Since the thickness of the inner cylindrical body is made thinner toward the cutting, the cutting portion can be easily opened, and the electric wire can be easily stored without applying an excessive force (claim) Item 2).
In addition, we prepared multiple types of outer cylinders with different inner diameters and used outer cylinders with diameters that matched the thickness of the wire bundle, so the inner cylinder was shared for various wire harnesses. And cost reduction can be achieved (claim 3).
Furthermore, by using both the inner cylinder and the outer cylinder as a corrugated tube, the accommodated wire harness can be bent and fixed in a desired direction (Claim 4), and the locking protrusion is divided and formed. Thus, the bending operation can be further facilitated (claim 5).
