Description

本発明は、ケーブルとその周囲の筒状体の間を固定するケーブル周設用ブッシュングに関するものである。   The present invention relates to a cable circumferential bushing that fixes a cable and a surrounding cylindrical body.

ケーブルの配索にあっては、ケーブル上に筒状体を固定したり、ケーブルと筒状体の間を防水構造とする場合がある。   In cable routing, a cylindrical body may be fixed on the cable, or a waterproof structure may be provided between the cable and the cylindrical body.

しかし、この場合にケーブルの表面は滑り易く、筒状体の固定が不十分であったり、十分な防水を行うことができないことも多い。   However, in this case, the surface of the cable is slippery, and the cylindrical body is often insufficiently fixed or cannot be sufficiently waterproofed.

本発明の目的は、上述の問題点を解消し、ケーブルを十分に緊締し、筒状体をケーブルに強固に固定し得るケーブル周設用ブッシュングを提供することにある。   An object of the present invention is to provide a cable circumferential bushing capable of solving the above-described problems, sufficiently fastening a cable, and firmly fixing a cylindrical body to the cable.

上述の目的を達成するための本発明に係るケーブル周設用ブッシュングの技術的特徴は、ケーブルの周囲に筒状体を間隙を隔てて固定する場合において、合成ゴムから成る略円筒状で外側にテーパ面を有するブッシュングを前記ケーブルに挿通すると共に、前記筒状体の端部に当接し、前記ブッシュングの前記テーパ面を外側から締め付けることにより、前記ブッシュングにより前記ケーブルを緊締すると共に前記ブッシュングを前記筒状体の端部に強く押し付けることにある。   The technical feature of the cable circumferential bushing according to the present invention for achieving the above-described object is that, when the cylindrical body is fixed around the cable with a gap, it is substantially cylindrical and made of synthetic rubber. A bushing having a taper surface is inserted into the cable, abutted against an end of the cylindrical body, and tightening the taper surface of the bushing from the outside, thereby tightening the cable with the bushing. The bushing is strongly pressed against the end of the cylindrical body.

本発明に係るケーブル周設用ブッシュングによれば、ケーブルへの固定強度を高めると共に筒状体に強固に当接できる。   According to the cable circumferential bushing according to the present invention, it is possible to increase the fixing strength to the cable and firmly contact the cylindrical body.

本発明を図示の実施例に基づいて詳細に説明する。
図1は本発明を適用した実施例の分解斜視図、図2は縦断面図である。ケーブル1a、1b中の多数本の電線2a、2bは、一対の合成樹脂製のコネクタ3a、3bにより接続されている。コネクタ3a、3b内には接続端子が収納され、これらの接続端子に電線2a、2bがそれぞれ接続されており、コネクタ3aと3bとを嵌合すると、双方の接続端子が電気的に接続されるようになっている。
The present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 is an exploded perspective view of an embodiment to which the present invention is applied, and FIG. 2 is a longitudinal sectional view. Many electric wires 2a and 2b in the cables 1a and 1b are connected by a pair of connectors 3a and 3b made of synthetic resin. Connection terminals are accommodated in the connectors 3a and 3b, and electric wires 2a and 2b are connected to these connection terminals. When the connectors 3a and 3b are fitted, both connection terminals are electrically connected. It is like that.

なお、コネクタ3a、3b同士の間は、図示しない合成ゴム製のシール部材により合わせ目から水が浸入しないようにされ、更に各電線2a、2bごとにコネクタ3a、3bのハウジングとの間がシール部材により同様にシールされているため、コネクタ3a、3bの前方又は後方からコネクタ3a、3b内に水が浸入することはない。   In addition, between the connectors 3a and 3b, water is prevented from entering from the joint by a synthetic rubber seal member (not shown), and further, the gap between the connectors 3a and 3b is sealed between the connectors 3a and 3b. Since the members are similarly sealed, water does not enter the connectors 3a and 3b from the front or rear of the connectors 3a and 3b.

本実施例では電線2a、2bの本数が多く、コネクタ3a、3b同士の嵌合、解除に大きな力を必要とするため、例えばコネクタ3aにはカム溝4を有する回動レバー5が設けられ、カム溝4に相手側コネクタ3bに設けたピン6を係止して、回動レバー5の回動によるてこ作用によってコネクタ3a、3b同士を大きな力を要せずに嵌合、解離できるようになっている。   In the present embodiment, the number of the electric wires 2a and 2b is large, and a large force is required for fitting and releasing between the connectors 3a and 3b. Therefore, for example, the connector 3a is provided with a rotating lever 5 having a cam groove 4, The pin 6 provided on the mating connector 3b is locked in the cam groove 4 so that the connectors 3a and 3b can be fitted and detached without requiring a large force by the lever action of the turning lever 5 turning. It has become.

コネクタ3aの後方には、合成樹脂製又は金属製の筒状プロテクタ7が連結されている。なお、コネクタ3bの後方にも同様な筒状プロテクタ7が配置され、コネクタ3aとほぼ対称の構造とされている。   A cylindrical protector 7 made of synthetic resin or metal is connected to the rear of the connector 3a. A similar cylindrical protector 7 is also arranged behind the connector 3b, and has a substantially symmetrical structure with the connector 3a.

筒状プロテクタ7内のコネクタ3a側は、コネクタ3aの後部を覆うと共に嵌合する形状に形成され、コネクタ3aとの間に合成ゴム製のシール部材8が介在されており、筒状プロテクタ7への前方からの水の浸入が阻止されている。   The connector 3 a side in the cylindrical protector 7 is formed in a shape that covers and fits the rear portion of the connector 3 a, and a synthetic rubber seal member 8 is interposed between the connector 3 a and the cylindrical protector 7. Ingress of water from the front of is prevented.

コネクタ3a、3bに連結された筒状プロテクタ7とケーブル1a、1bの絶縁被覆9間には、筒状プロテクタ7の後方から、合成ゴムから成る筒状で内外面に断面波型を形成したグロメット10が挿入され、筒状プロテクタ7内は防水構造とされている。   Between the cylindrical protector 7 connected to the connectors 3a and 3b and the insulation coating 9 of the cables 1a and 1b, a grommet having a cylindrical shape made of synthetic rubber and having a cross-sectional corrugation on the inner and outer surfaces from the rear of the cylindrical protector 7 10 is inserted, and the inside of the cylindrical protector 7 has a waterproof structure.

更に、絶縁被覆9上には合成ゴム製で後部にテーパ部11aを有するブッシュング11、ブッシュング11のテーパ部11aに当接する形状のテーパ面を有する環状形の金属製スリーブ12、金属製又は金属樹脂製のナット13が装着されている。   Further, on the insulating coating 9, a bushing 11 made of synthetic rubber and having a taper portion 11a at the rear portion, an annular metal sleeve 12 having a tapered surface in contact with the taper portion 11a of the bushing 11, a metal or A metal resin nut 13 is attached.

また、コネクタ3a、3b、筒状プロテクタ7の上に、合成樹脂製又は金属製の2つ割りの保護筒14が被着され、両端においてナット13により固定されている。   Further, a protective resin 14 divided into two parts made of synthetic resin or metal is attached on the connectors 3a and 3b and the cylindrical protector 7, and is fixed by nuts 13 at both ends.

組立時には、ナット13、スリーブ12、ブッシュング11の順で絶縁被覆9上に挿通し、続いてグロメット10、筒状プロテクタ7を挿通する。   At the time of assembly, the nut 13, the sleeve 12, and the bushing 11 are inserted through the insulating coating 9, and then the grommet 10 and the cylindrical protector 7 are inserted.

ここで、各電線2aに接続端子を接続してから、全ての接続端子をコネクタ3aに挿着し、コネクタ3aを同様に処理したコネクタ3bと嵌合する。続いて、筒状プロテクタ7をコネクタ3a側に引き寄せ、筒状プロテクタ7をコネクタ3aに連結してから、絶縁被覆9と筒状プロテクタ7の後部の隙間にグロメット10を押し込み、筒状プロテクタ7の内部を防水構造とする。   Here, after connecting a connection terminal to each electric wire 2a, all the connection terminals are inserted into the connector 3a, and the connector 3a is fitted with the connector 3b processed similarly. Subsequently, the tubular protector 7 is pulled toward the connector 3 a side, the tubular protector 7 is connected to the connector 3 a, and then the grommet 10 is pushed into the gap between the insulating coating 9 and the tubular protector 7, so that the tubular protector 7 The interior is waterproof.

更に、2つ割りの保護筒14をコネクタ3a、3b、筒状プロテクタ7の周囲に被着し、保護筒14のねじ部14aにナット13を螺合して、2つ割りの保護筒14同士を一体化する。   Further, the split protective cylinder 14 is attached to the periphery of the connectors 3a, 3b and the cylindrical protector 7, and the nut 13 is screwed into the screw portion 14a of the protective cylinder 14, so that the split protective cylinders 14 are connected to each other. Is integrated.

このように、ナット13を締め付けることにより、図3に示すようにスリーブ12がブッシュング11のテーパ部11aをその法線方向に、締付力Aにより押さえ付ける。つまり、ブッシュング11のテーパ部11aには、スリーブ12を介してナット13の締付力Aが加わる。この締付力Aは絶縁被覆9の方向に対するベクトルBと保護筒14の端部を押すベクトルCに分けられ、それぞれベクトルBとベクトルCの力に対応して絶縁被覆9と保護筒14の端部を強い力で押さえ付ける。   In this way, by tightening the nut 13, the sleeve 12 presses the tapered portion 11 a of the bushing 11 in the normal direction with the tightening force A as shown in FIG. 3. That is, the tightening force A of the nut 13 is applied to the tapered portion 11 a of the bushing 11 via the sleeve 12. This tightening force A is divided into a vector B that pushes the end of the protective cylinder 14 with respect to the direction of the insulating cover 9, and the end of the insulating cover 9 and the protective cylinder 14 corresponding to the force of the vector B and vector C, respectively. Press the part with a strong force.

ベクトルBの力により絶縁被覆9はブッシュング11により強い緊締力により締め付けられ、多少の外力が加わっても、ブッシュング11は絶縁被覆9に対しずれるようなことはない。同時に、ブッシュング11はベクトルCの力により保護筒14の端部を強く前方に押さえ付けるため、保護筒14の絶縁被覆9に対する位置関係が保持されることになる。   The insulating coating 9 is fastened by the bushing 11 with a strong tightening force by the force of the vector B, and the bushing 11 does not shift with respect to the insulating coating 9 even if a slight external force is applied. At the same time, the bushing 11 strongly presses the end of the protective cylinder 14 forward by the force of the vector C, so that the positional relationship of the protective cylinder 14 with respect to the insulating coating 9 is maintained.

このような構成により、ケーブル1aに保護筒14が固定されることになり、ケーブル1aに捩れ、伸縮が加わっても、これらの力はブッシュング11を介して保護筒14が受けることになる。なお、ケーブル1b側においても同様である。   With such a configuration, the protective cylinder 14 is fixed to the cable 1 a, and even if the cable 1 a is twisted and expanded or contracted, these forces are received by the protective cylinder 14 via the bushing 11. The same applies to the cable 1b side.

なお、本実施例においては、保護筒14は2つ割り構造であるため、ブッシュング11が防水機能を果たすことはない。しかし、保護筒14が密閉型であれば、ブッシュング11は絶縁被覆9と保護筒14間に強固に介在されているので、ブッシュング11により保護筒14内への水の浸入を防止することができる。   In this embodiment, since the protective cylinder 14 has a split structure, the bushing 11 does not perform a waterproof function. However, if the protective cylinder 14 is hermetically sealed, the bushing 11 is firmly interposed between the insulating coating 9 and the protective cylinder 14, so that the bushing 11 prevents water from entering the protective cylinder 14. Can do.
