用して接続する。 Now, the present invention relates to a novel configuration of the jumper device 12 having the above configuration. Referring to FIG. 2, one embodiment of the jumper device according to the present invention is shown, and 15a is a rigid column made of an insulating plastic material such as concrete and having a round cross section. 17a is a conductive metal that replaces the jumper wire 17 that is supported by the spacer 16 along with the rigid support member 15 in FIG. 1, and a plurality of wires are integrally embedded in the concrete column 15a. . The conductive metal 17a is preferably one that satisfies the power transmission function better than ordinary electric wires and can also serve as a reinforcing material for the concrete column 15a. The jumper wire is connected using a terminal or the like.

８のごとく吊り具にて吊ることができるよう支持
部を設けてもよい。 FIG. 3 15b shows another embodiment. In this case, one conductive metal 17b which also serves as a reinforcing material is used in common. Therefore, a plurality of jumper wires are connected at both ends of the conductive metal 17b. The jumper wire and conductive metal are connected via a terminal, sleeve, etc. The embodiment shown in Fig. 2 is installed as shown in Fig. 5 and does not use hanging rods, but the embodiment shown in Fig. 3
A support part may be provided as shown in 8 so that it can be hung with a hanging device.
第４図はさらに別の実施例である。この場合に
は、コンクリート製柱体１５ｃの断面形状を十分
形にしたもので、これによりコンクリートの節約
と軽量化を図ることができると共に強度を増す事
ができる。 FIG. 4 shows yet another embodiment. In this case, the cross-sectional shape of the concrete column 15c is sufficiently shaped, thereby making it possible to save concrete and reduce the weight, as well as increasing the strength.
以上本発明によれば、
(1) 柱体の断面形状を自由に採択することがで
き、しかも導電性金属が柱体の補強を兼ねるの
で、形状の縮少化、ならびに軽量化が可能であ
る。 As described above, according to the present invention, (1) the cross-sectional shape of the column can be freely selected, and since the conductive metal also serves as reinforcement of the column, it is possible to reduce the size and weight; .
(2) ジヤンパ線は導電性金属の両端につけるのみ
でよいので、装置を組立てたりジヤンパスペー
サなどにジヤンパ線をとりつける作業がないた
め、取付作業が容易であり、省力化に寄与する
ものである。(2) Since the jumper wires only need to be attached to both ends of the conductive metal, there is no need to assemble the device or attach the jumper wires to jumper spacers, etc., making the installation process easy and contributing to labor savings. .
(3) ジヤンパスペーサや取付金具などを要しな
い。(3) No need for jumper spacers or mounting hardware.
(4) 厳しい気象条件下でも装置や電線の破壊・損
傷がないので安定した性能を期待できる。(4) Stable performance can be expected because there is no destruction or damage to equipment or wires even under severe weather conditions.
(5) コンクリートで成形し、中に導電性金属をう
めこんである為鉄損の心配がない。(5) There is no need to worry about iron loss as it is molded from concrete and has conductive metal embedded inside.
