成される。 The terminations or straight connections of plastic insulated cables, such as cross-linked polyester insulated cables (hereinafter referred to as "CV cables"), are exposed to air, N 2 , SF 6 ,
In some cases, the structure is filled with a gas such as freon or an insulating liquid such as silicone oil under pressure or normal pressure. A sealed structure is constructed by covering the fitting with rubber or plastic and heat molding it.
しかし、これまで、充填された気体又は液体が
もれたか否か検出管理することが困難であつた。 However, until now, it has been difficult to detect and manage whether the filled gas or liquid has leaked.
本考案の目的は、前記した従来技術の欠点を解
消し、容易にケーブル接続部の充填気体又は液体
のもれを検出管理できるプラスチツク絶縁ケーブ
ル接続部の密封構造を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a sealing structure for a plastic insulated cable connection part that overcomes the drawbacks of the prior art described above and can easily detect and manage leakage of filling gas or liquid from the cable connection part.
すなわち、本考案の要旨は、プラスチツク絶縁

し、管理できるようにしたことを特徴とする。 That is, the gist of the present invention is that, in the sealed structure of a plastic insulated cable connection part, a double packing part is provided between the embedded fitting and the sealing fitting, and a double packing part is provided between the packing parts on the sealing fitting. It is characterized in that a void is provided that penetrates to the outside through the hole, so that leakage of the filled gas or liquid can be detected and managed using a detection device or visual inspection.
以下、本考案を添付図面を参照して具体的に説
明する。 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
第１図は本考案を実施した例を示す断面説明図
で、第２図は、その要部拡大図である。 FIG. 1 is an explanatory cross-sectional view showing an example of implementing the present invention, and FIG. 2 is an enlarged view of the main parts thereof.
CVケーブル１の外周には埋込金具２が配置さ

具４が取り付けられ、さらに上側金具５と下側金
具６が設置されている。上側金具５側には例えば
シリコン油等の液体７が封入され、下側金具６側
には例えば、空気、N2，SF6、フレオン等の不活
性な気体８が封入されている。尚、上側、下側と
も気体或は液体が封入されている場合もある。 An embedded fitting 2 is arranged around the outer circumference of the CV cable 1, and is fixed with a mold 3 made of rubber, plastic, or the like. A sealing fitting 4 is attached to the outer periphery of the embedded fitting 2, and an upper fitting 5 and a lower fitting 6 are further installed. A liquid 7 such as silicone oil is sealed in the upper metal fitting 5 side, and an inert gas 8 such as air, N 2 , SF 6 , Freon, etc. is sealed in the lower metal fitting 6 side. Note that gas or liquid may be filled in both the upper and lower sides.
封止金具４には埋込金具２に接する側にパツキ

ることもできる。 The sealing fitting 4 is provided with double packing parts 9 and 10 on the side that contacts the embedded fitting 2.
A gap 11 is provided between the holes 1 and 1, and the gap 11 communicates with the outside through a hole 12 provided in the sealing fitting 4 and penetrating to the outside. Although a detection end directly connected to the detection device 13 through the hole 12 can be installed in the cavity 11, the cavity 11 can also be directly observed.
従つて、本考案は、上記したように密封構造を
構成したので、簡単な構造で気体又は液体充填物
質がもれた場合、空隙部１１で容易に検知するこ
とが可能で、常時、もれの管理をすることがで
き、その実用価値は極めて大きいものがある。 Therefore, since the present invention has a sealed structure as described above, it is possible to easily detect leakage of gas or liquid filling substance in the cavity 11 with a simple structure, and to prevent leakage at all times. can be managed, and its practical value is extremely large.
