Description
本発明は、ケーブルを配線箱の貫通穴に通線する際に、壁材の縁部にケーブルが接触して損傷を起こさないように配線保護するケーブルブッシングに関する。 The present invention relates to a cable bushing that protects a wiring so that the cable does not come into contact with an edge of a wall material to cause damage when the cable is passed through a through hole of a wiring box.
例えば、従来よりケーブルを配線箱の貫通穴に通線する際に使用されるケーブルブッシングの構成として、特許文献１を挙げる。 For example, Patent Document 1 is cited as a configuration of a cable bushing that is conventionally used when a cable is passed through a through hole of a wiring box.
この特許文献１は、電子機器装置の外郭または内壁を貫通する配線が壁部の縁部に直接に接触して起こる損傷から保護するための配線保護グロメットである。 This patent document 1 is a wiring protection grommet for protecting a wiring penetrating an outer wall or an inner wall of an electronic device device from damage caused by directly contacting an edge of a wall portion.
特許文献1は、グロメットに磁性材を内蔵して、電子機器外部から内部に侵入するノイズを防ぐことができるとともに、凹部２によって、貫通穴の壁材の縁部によるケーブルの損傷からケーブルの外被を保護するものではあるが、配線箱の壁の板厚によっては、凹部２の寸法を合わせる必要があるものであり、生産するためのコストが増大するおそれがあった。 In Patent Document 1, a grommet incorporates a magnetic material to prevent noise from entering the inside from the outside of the electronic device, and the recess 2 prevents the cable from being damaged by the edge of the wall material of the through hole. Although it protects the covering, depending on the thickness of the wall of the wiring box, it is necessary to match the dimensions of the recess 2, which may increase the cost for production.
さらに、特許文献1のような従来のケーブル保護部材（ブッシング、グロメット等）は、ケーブル保護部材とケーブルの径に差がある場合においての十分な防滴性までは考慮されていなかった。 Further, the conventional cable protection member (bushing, grommet, etc.) as in Patent Document 1 does not take into account sufficient drip-proof properties when there is a difference between the cable protection member and the cable diameter.
本発明の課題は、ケーブルを配線箱の貫通穴に通線する際に、壁材の縁部にケーブルが接触して損傷を起こさないように配線保護するとともに、防滴性を備え、配線箱の多種の板厚にも対応できるようにすることにある。 An object of the present invention is to protect the wiring so that the cable does not come into contact with the edge of the wall material and cause damage when passing the cable through the through hole of the wiring box. It is to be able to cope with various plate thicknesses.
上記課題を解決するために、本発明は、配線箱の壁部に設けられた貫通穴にケーブルを通線する通線構造において、前記貫通穴の縁部からケーブルを保護するケーブルブッシングであって、前記貫通穴の縁部を嵌め込むための凹部を有してなり、前記凹部に舌片部を設けたケーブルブッシングであることを特徴とする。
また、請求項２は、前記凹部の舌片部と対向する位置に突起部を設けたことを特徴とする。さらに、請求項３は、ケーブルブッシングが、一端を円筒形状とし、他端を暫時縮径した形状とすることを特徴とする。
In order to solve the above problems, the present invention provides a cable bushing for protecting a cable from an edge portion of the through hole in a through structure in which the cable is passed through a through hole provided in a wall portion of a wiring box. A cable bushing having a recess for fitting the edge of the through hole and having a tongue piece in the recess.
According to a second aspect of the present invention, a projection is provided at a position facing the tongue piece of the recess. Further, the cable bushing according to claim 3 is characterized in that one end has a cylindrical shape and the other end has a reduced diameter for a while.
上記構成により、本発明によれば、配線箱の壁部に設けられた壁の貫通穴によりケーブルを通線する際に、ケーブルブッシングの舌片部を有する凹部の作用により、防滴性を備えるとともに、配線箱の多種の板厚に対応することができる。 With the above configuration, according to the present invention, when the cable is routed through the wall through-hole provided in the wall portion of the wiring box, drip-proofing is provided by the action of the concave portion having the tongue portion of the cable bushing. In addition, it is possible to cope with various plate thicknesses of the wiring box.
本発明の好適な実施の形態を図面に基づいて説明する。
図１に本発明のケーブルブッシングの全体斜視図、図２に本発明のケーブルブッシングの断面図、図３に壁部の板厚が異なる（ａ）（ｂ）のそれぞれの場合の配線箱の貫通穴の縁部にケーブルブッシングの舌片部および突起部を有する凹部が嵌め込まれた状態の拡大図、図４に配線箱にケーブルブッシングが嵌め込まれた図である。
Preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an overall perspective view of the cable bushing of the present invention, FIG. 2 is a cross-sectional view of the cable bushing of the present invention, and FIG. 3 shows the penetration of the wiring box in each of the cases (a) and (b) with different wall thicknesses. FIG. 5 is an enlarged view of a state in which a recess having a tongue portion and a protrusion of a cable bushing is fitted in the edge of the hole, and FIG. 4 is a diagram in which the cable bushing is fitted in the wiring box.
ケーブルブッシング１は、ケーブル８を配線箱９に通線させるための挿通部５を軸線方向に有してなり、一端（外端側）を円筒部２とし、他端（内端側）を軸線方向に暫時縮径した円筒部３とし、舌片部６および突起部７を有する凹部４を有した形状とする。
また、ケーブルブッシング１は、ゴム等の弾性部材により一体に形成されている。
The cable bushing 1 has an insertion portion 5 for passing the cable 8 through the wiring box 9 in the axial direction, one end (outer end side) is a cylindrical portion 2, and the other end (inner end side) is an axis. A cylindrical portion 3 having a diameter reduced in the direction for a while and a shape having a concave portion 4 having a tongue piece portion 6 and a protruding portion 7 are formed.
The cable bushing 1 is integrally formed of an elastic member such as rubber.
軸線方向に暫時縮径した円筒部３とすることにより、ケーブルブッシング１を配線箱９の貫通穴１０に嵌め込みやすくしているものである。なお、縮径した円筒部３は、この形状に限定するものではなく、貫通穴１０に嵌め込むことができる形状であればよい。 By using the cylindrical portion 3 that is temporarily reduced in diameter in the axial direction, the cable bushing 1 is easily fitted into the through hole 10 of the wiring box 9. Note that the reduced diameter cylindrical portion 3 is not limited to this shape, and may be any shape that can be fitted into the through hole 10.
凹部４は、円筒部２と、縮径した円筒部３の境界部分に形成されており、円筒部２と一体につながって円筒部２から他端に向かって形成された舌片部６と、前記舌片部６と対向する位置に設けられ、縮径した円筒部３と一体につながって、縮径した円筒部３から一端に向かって形成された突起部７を有してなる。 The concave portion 4 is formed at a boundary portion between the cylindrical portion 2 and the cylindrical portion 3 having a reduced diameter, and is connected to the cylindrical portion 2 so as to be integrated with the tongue piece portion 6 formed from the cylindrical portion 2 toward the other end. It is provided at a position facing the tongue piece 6, and is integrally connected to the reduced diameter cylindrical portion 3, and has a protruding portion 7 formed from the reduced diameter cylindrical portion 3 toward one end.
凹部４の突起部７の作用により、配線箱９の壁の貫通穴１０にケーブルブッシング１を嵌め込んだ際に配線箱９の内壁から密接させて防滴性を確保することができる。 Due to the action of the protrusion 7 of the recess 4, when the cable bushing 1 is fitted into the through hole 10 in the wall of the wiring box 9, the cable bushing 1 is brought into close contact with the inner wall of the wiring box 9 to ensure drip-proofness.
舌片部６は、その弾性力により、異なった板厚の場合であっても、図3（ａ）（ｂ）のように十分に対応することができ、板厚を吸収して配線箱９の外壁に密接して防滴性を確保することができる。また、舌片部６の形状は、本実施例の形状に限定されるものではなく、板厚を吸収して配線箱９の外壁に密接して防滴性を確保することができる形状であればよい。 Even if the tongue piece 6 has different plate thicknesses due to its elastic force, it can sufficiently respond as shown in FIGS. 3 (a) and 3 (b). It is possible to ensure drip-proofness in close contact with the outer wall. In addition, the shape of the tongue piece 6 is not limited to the shape of the present embodiment, and may be a shape that can absorb the plate thickness and be in close contact with the outer wall of the wiring box 9 to ensure the drip-proof property. That's fine.
挿通部５は、ケーブルの径と同じ径で形成され、ケーブル外周面に密接してケーブルを配線箱に通線する。 The insertion portion 5 is formed with the same diameter as the cable, and is in close contact with the outer peripheral surface of the cable and allows the cable to pass through the wiring box.
次に、配線箱の貫通穴へのケーブルブッシングの取り付け動作について説明する。
図４に示すように、貫通穴１０に対し、ケーブルブッシング１の縮径した円筒部３を配線箱９の壁の内側に押し込むと、凹部４の突起部７に壁の縁部１０ａが到達し、凹部４に壁の縁部１０ａが嵌まり込んで、突起部７が配線箱９の内側から壁に密接する。
図３に示すように、凹部４に壁の縁部１０ａに嵌まり込んだ時に、舌片部６がその弾性力によって、壁の板厚を吸収し、配線箱９の外側から壁に密接する。
これによって、防滴性を確保してケーブルブッシング１が、配線箱９の貫通穴１０ａに取り付けられる。
ケーブル８は、ケーブルブッシング１が取り付けられた後に、挿通部５に挿通され、配線箱９内に通線される。
Next, the operation of attaching the cable bushing to the through hole of the wiring box will be described.
As shown in FIG. 4, when the cylindrical portion 3 with the reduced diameter of the cable bushing 1 is pushed into the inside of the wall of the wiring box 9 with respect to the through hole 10, the edge portion 10 a of the wall reaches the protruding portion 7 of the recess 4. The edge portion 10 a of the wall is fitted into the recess 4, and the protrusion 7 is in close contact with the wall from the inside of the wiring box 9.
As shown in FIG. 3, the tongue piece 6 absorbs the plate thickness of the wall by its elastic force when it is fitted to the edge 10 a of the wall in the recess 4, and comes into close contact with the wall from the outside of the wiring box 9. .
Accordingly, the cable bushing 1 is attached to the through hole 10 a of the wiring box 9 while ensuring drip-proof property.
The cable 8 is inserted into the insertion portion 5 after the cable bushing 1 is attached, and is passed through the wiring box 9.
以上の構成により、配線箱の壁部に設けられた壁の貫通穴によりケーブルを通線する際に、ケーブルブッシングの舌片部を有する凹部の作用により、防滴性を備えるとともに、配線箱の多種の板厚に対応することができる。 With the above configuration, when the cable is routed through the wall through-hole provided in the wall portion of the wiring box, the concave portion having the tongue portion of the cable bushing provides drip-proofness, and Various plate thicknesses can be accommodated.
