A. Industrial Application Field The present invention relates to a conductor connection cover. B. Overview of the invention The present invention provides a heat-resistant conductor connection part cover that covers the conductor connection part, which consists of a cylindrical part that covers the conductor connection part and hemispherical parts formed at both ends of this cylindrical part and having conductor insertion holes. By constructing the cover from conductive polymer and having a split structure, it is possible to obtain a heat-resistant conductor connection cover that does not concentrate electric fields, is lightweight, and has good mass production and workability. This is what I did. C. Prior Art The joints between conductors are covered with conductor connection covers for the purpose of protecting the joints. As a conventional conductor connection cover, there is one shown in FIG. In the figure, 1 is a conductor, 2 is a crimp terminal attached to the conductor 1 and connected to each other via a bolt 3 and a nut 4, 5 is an insulating vinyl tape that matches the insulation of the conductor 1, and 6 is attached to the conductor 1. 7 is a housing attached via the conductor through ground 6, and 8 is a urethane-based filler injected into the housing 7. With such a conductor connection cover, proper connection can be made without causing a decrease in insulation. D Problems to be solved by the invention However, since insulating vinyl taping 5 and urethane filler 8 are used, they tend to deteriorate due to heat, and since both ends of the casing 7 are sharp, the electric field concentrates and causes flash. There was a risk of interference. Furthermore, the housing 7
Because it did not have a split structure, it was large, heavy, and had poor workability. E. Means for Solving the Problems In order to solve the above conventional problems, the present invention provides a cylindrical part made of a heat-resistant conductive polymer and having a substantially cylindrical shape and housing a conductor connection part therein; It consists of hemispherical parts formed at both ends of this cylindrical part and made of heat-resistant conductive polymer, the outer circumferential surface of which is approximately hemispherical and has an insertion hole in the center through which the conductor is inserted. The conductor connection part cover is constructed as a freely divided structure. In the present invention, thermosetting resins, thermoplastic resins, rubber, etc. are used as the heat-resistant conductive polymer, and the heat-resistant temperature should satisfy a maximum of 105°C (IEC694-1980). To make resin conductive, there are methods such as forming a conductive layer on the surface of the resin or adding a conductive filler to the resin. To form a conductive layer on the surface of a resin, a conductive paint is applied to the surface of a thermosetting or thermoplastic resin by vacuum deposition, sputtering, ion plating, plating, or the like. Here, as the conductive paint, silver, nickel, copper, graphite, etc. are used, and as the binder, acrylic or polyurethane resin is used. Further, the conductive layer may be formed, for example, by spraying a metal such as zinc or by providing a metal foil. In the method of adding a conductive filler to the resin, epoxy resin is used as the thermosetting resin, and polypropylene, polystyrene, ABS (acrylonitrile-butadiene-styrene copolymer resin), PVC ( polyvinyl chloride), modified PPO (polyphenylene oxide)

Nickel, stainless steel, tin oxide), carbon fiber, aluminum ribbon, aluminum coated glass fiber, etc. On the other hand, examples of conductive rubber include EP rubber, ethylene acrylic rubber, silicone rubber, and fluorocarbon rubber.
Acetylene black, conductive furnace black, nickel particles, etc. are used. F Effect Connect the conductors with each other with the conductor connection part cover divided, and then combine the divided conductor connection part covers to cover the connection part of the conductor. Since the outer peripheral surface of the conductor connection portion cover has no corners and is rounded, flash shorting due to electric field concentration is prevented. G Example Hereinafter, the present invention will be described in detail based on an example shown in FIGS. 1 and 2. FIG. 2 is a sectional view of each component constituting the conductor connection portion cover. The conductor connection portion cover 11 is composed of a cylindrical portion 12 and hemispherical portions 13 coupled to both ends of the cylindrical portion 12. The cylindrical portion 12 has a cylindrical shape so that a conductor connection portion can be accommodated therein and electric field concentration does not occur, and is made of a heat-resistant conductive polymer material. In order to make it detachable from the hemispherical part 13, male threads 12a are formed at both ends of the cylindrical part 12. The hemispherical portion 13 is for closing both ends of the cylindrical portion 12, and is also made of a heat-resistant conductive polymer material. The hemispherical portion 13 also has a hemispherical outer peripheral surface to prevent electric field concentration, and has a female thread 1 for screwing into the male thread 12a.
3a is formed. In the center of the hemisphere 13,
Insertion hole 1 for inserting both conductors to be connected
3b is drilled. Next, the procedure for attaching such a conductor connection portion cover will be explained based on FIG. 1. In advance, one hemisphere part 1
The conductor 1 is inserted into the insertion hole 13b of No. 3 and the inside of the cylindrical portion 12.
4 and the conductor 15 is inserted into the insertion hole 13b of the other hemispherical portion 13. Next, connect the conductors 14 and 15 via the bolt 16 and nut 17,
After moving the cylindrical part 12 to this connection part, the hemispherical parts 13 are screwed into both ends of the cylindrical part 12. In the above embodiment, the conductor connection portion cover 11 is divided into three parts, but the present invention is not limited to this embodiment, and may have a two-part structure, for example. H. Effects of the invention As described above, according to the conductor connection part cover of the invention, the outer peripheral surface of the cover has no sharp parts and is formed into a circular surface, so the electric field concentration coefficient is small and the flashover value is large. . In particular, when connecting conductors in a space insulated with gas such as SF 6 gas, the electric field tends to concentrate, so the effect of preventing flashover is great. In addition, the conductor connection part cover is made of heat-resistant conductive polymer, so it is lightweight and easy to work with, has excellent mass production and processability, is low cost, and can be made of flexible material. , the cover divided pieces can be easily connected by simply fitting or pushing them together, further improving workability.
