本発明は、多心型ケーブル接続部の形成方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of forming a multi-core cable connection.
多心型ケーブル接続部は、複数本のケーブル心線と接子
を、あるいはケーブル心線相互を接続スリーブで接続し
て端末処理部を形成し、この端末処理部を埋め込むよう
にゴム絶縁ブロックを形成した構造となっている。A multi-core cable connection section connects multiple cable core wires and a joint or each cable core wire with a connecting sleeve to form a terminal processing section, and a rubber insulating block is placed so as to embed this terminal processing section. It has a formed structure.
このような多心型ケーブル接続部のゴム絶縁ブロックは
従来、コンブレフシラン法、トランスファー法、射出法
などによって形成されている。コンプレ、シラン法とは
、端末処理部の外周にゴムを巻き付け、これを圧縮成形
型に入れて圧縮成形する方法で゛あり、トランスファー
法とは、端末処理部を成形型内にセットした後、その型
の上部に配置したゴムを押圧して型内に圧入する方法で
あり、射出法とは、端末処理部を成形型内にセットした
後、ゴムをスクリューで押し出して型内に圧入する方法
である。Rubber insulating blocks for such multi-core cable connections have conventionally been formed by a combination method, a transfer method, an injection method, or the like. The compressor silane method is a method in which rubber is wrapped around the outer periphery of the end treatment part, and the rubber is placed in a compression mold and compression molded.The transfer method is a method in which after the end treatment part is set in the mold, This is a method of pressing the rubber placed on the top of the mold and press-fitting it into the mold.The injection method is a method of setting the end treatment part in the mold and then extruding the rubber with a screw and press-fitting it into the mold. It is.
しかし上記の各方法は、いずれも加圧成形法であるため
、ゴム絶縁ブロック成形時に多心型ケーブルの端末処理
部に圧力がかかり、多心型ケーブルの心線が細い場合や
心線数が多い場合には、心線の伸びや断線あるいは接子
の曲がりや接触等が発生するという問題があった。However, since each of the above methods is a pressure molding method, pressure is applied to the end treatment part of the multi-core cable when molding the rubber insulation block. If there is a large amount, there is a problem that elongation or breakage of the core wire or bending or contact of the connector may occur.
このため従来、心線が細い場合や心線数が多い場合には
、１本１本に上記成形方法によりゴム絶縁ブロックを形
成した後、それらをまとめて再度全体のゴム絶縁ブロッ
クを形成するという方法も採用されている。しかしこの
ような二度成形は手間がかかるだけでなく、接続部のサ
イズが大型化する欠点がある。For this reason, conventionally, when the core wires are thin or there are a large number of core wires, a rubber insulating block is formed for each core by the above molding method, and then they are put together to form the entire rubber insulating block again. method has also been adopted. However, such double molding is not only time-consuming, but also has the drawback of increasing the size of the connecting portion.
本発明は、上記のような従来技術の課題を解決する多心
型ケーブル接続部の形成方法を提供するもので、その方
法は、多心型ケーブル端末処理部を成形型にセットし、
しかる後その成形型内に液状ゴムを注入して硬化させる
ことを特徴とするものである。The present invention provides a method for forming a multi-core cable connection part that solves the problems of the prior art as described above, and the method includes: setting a multi-core cable end processing part in a mold;
The feature is that liquid rubber is then injected into the mold and cured.
このようにすれば、液状ゴム注入の際、多心型ケーブル
の端末処理部に圧力がかからなくなるので、心線の伸び
や断線あるいは接子の曲がりや接触等が発生するおそれ
がなくなり、また接続部を大型化しないで済む。In this way, when liquid rubber is injected, no pressure is applied to the end treatment part of the multi-core cable, so there is no risk of stretching or breaking the core wires or bending or contacting the connectors. There is no need to increase the size of the connection part.
また多心型ケーブルの端末処理部に、ケーブル内部の空
気が成形型内に流入するのを防止するシール部を設けて
おくと、成形型内に液状ゴムを注入した際、液状ゴム中
に気泡が発生せず、電気的、機械的、外観的に優れたゴ
ム絶縁ブロックを形成することが可能である。In addition, if a seal part is provided at the end treatment part of a multi-core cable to prevent the air inside the cable from flowing into the mold, when liquid rubber is injected into the mold, air bubbles will form in the liquid rubber. It is possible to form a rubber insulating block that is excellent in electrical, mechanical, and external appearance without causing any

を使用することができる。The terminal processing portion 6 formed as described above is placed in a mold 7.
Set inside. The mold 7 is composed of a main body part 7a that can be split into two in the axial direction of the multi-core cable l, and a front plate 9 fixed to the front surface of the main body part 7a with bolts 8. An insertion hole 9a for the wire 5 is formed. Further, an injection lower b is formed in the main body portion 7a, and the liquid rubber 10 is poured into the mold 7 from the injection lower b. Polyurethane rubber, silicone rubber, etc. can be used as the liquid rubber 10.
注入された液状ゴム１０は所定時間後に硬化し、ゴム絶
縁ブロックとなるから、硬化後、成形型７を取り外し、
注入口の突起を切除すれば、多心型ケーブル接続部を得

曲がりなどを生じさせることなくゴム絶縁ブロックを形
成することができる。Since liquid rubber does not require pressure to be applied to the end treatment section of a multi-core cable when injected, a rubber insulation block can be formed without elongation or cutting of the core wires or bending of the joints.
図−２は本発明の他の実施例を示す。前記実施例と相違
するのは多心型ケーブルの端末処理部の構造である。FIG. 2 shows another embodiment of the present invention. The difference from the previous embodiment is the structure of the terminal processing section of the multi-core cable.
すなわちケーブルシース１ａの端部から心線ｌＣ１接続
スリーブ２に跨がってシール部１１ａを形成すると共に
、接続スリーブ２と接子３にかけてもシール部１１ｂを
形成したことである。That is, a seal portion 11a is formed extending from the end of the cable sheath 1a to the cable core 1C1 connection sleeve 2, and a seal portion 11b is also formed from the end of the cable sheath 1a to the connection sleeve 2 and the joint 3.

。By providing such a seal portion 11a41b, it is possible to prevent the air inside the multi-core cable 1 from flowing into the mold 7. Therefore, when the liquid rubber 10 is injected into the mold 7, no bubbles are generated in the liquid rubber 10, and electrical, mechanical, and appearance defects of the rubber insulating block can be reliably prevented.

に跨がる部分だけにシール部を設ければよい。As a method for forming the seal portion 11a41b, any method such as a dipping method, a spray method, and a spacing method can be adopted. Further, the material of the seal portions 11a and 11b is preferably the same as liquid rubber. Furthermore, the seal part is provided to prevent the air inside the cable from flowing into the mold, so if there is no risk of air flowing through the conductor part inside the core wire, the seal part is provided to prevent the air inside the cable from flowing into the mold. It is sufficient to provide a seal portion only in the portion that straddles the line.
なお上記各実施例においては、多心型ケーブルの心線導

続部を形成することができる。As described above, in the present invention, after the end treatment part of the multi-core cable is set in the mold, liquid rubber is injected into the mold and cured, so that pressure is applied to the end treatment part of the multi-core cable. Therefore, even when the core wires of a multi-core cable are thin or the number of core wires is large, there is no elongation or breakage of the core wires, or bending or contact of the joints, etc.
It is possible to form a small multi-core cable connection part that is electrically and mechanically reliable.
