ルドされている。[Prior Art] Generally, in the launch switch of a high-voltage overhead power distribution line or the lead wire of a single transformer electrical device, terminal fittings are used to enable it to be incorporated into the insulator of the electrical device. An insulating member such as butyl rubber or ethylene propylene rubber, which is resistant to lagging, is molded on the periphery of the end on the side several steps apart.

ドに使用する金型には縦方向の金型合わせ目のない無分
割のものが用いられる。By the way, this type of lead wire is often used in places where it is easily contaminated by salt, dust, etc. Therefore, the surface of the molded part of the insulating member mentioned above should be made as smooth as possible to prevent electrical traces. It is desirable to make it difficult for L-ring to occur. For this reason, the presence of vertical lines, etc., where leakage current is likely to flow, is considered unsuitable, and the molds used for molding insulating materials must be undivided, with no vertical mold seams. used.
「発明が解決しようとする問題点コ
しかしながら、無分割の金型を用いた場合には、次の様
なテ11点があった。``Problems to be solved by the invention However, when using an undivided mold, there were the following 11 problems.

酋通である。Immediately J5, this lead wire is usually 1 to 2 mmf! i! In this method, an insulated wire made of 1-racking-resistant butyl rubber or ethylene propylene rubber that has been cut repeatedly is used, and the insulating member is molded onto one end of the insulated wire.

る事が困ガとなる。Therefore, if we consider (1) to prevent the insulating member from flowing out during molding, the inner surface of the lead wire type through hole/41 of the mold 011 section should be
It is desirable that it be in closer contact with the surface of the grid line. However, as shown in FIG.
After the ruby, the mold 40 needs to be moved back to the right side in the figure along the entire length of the exit line 1. Therefore, if the mold 40 is too tight against the exit line 1, the mold 40 cannot be slid. !
It becomes difficult to do so.

Therefore, the insulating member 10 does not firmly adhere to the surface of the grid line 1, and the part q11 is separated. It becomes easier.

A first mold 4 of an undivided type having a cylindrical inner surface 3 having an inner diameter 1 to 2 thresholds larger than the maximum outer diameter extending to its other end; One end of the first mold 4 is provided with the mold 4, and one end of the first mold 4 is placed in contact with the mold 4 and has a lead wire type through hole 5 in the internal axis direction thereof.
a second mold 6 of an undivided type having
The mold 4 is placed in contact with the other end thereof, and has a lead wire insertion hole 7 having an inner diameter that matches the outer diameter of the lead wire 1 in the direction of its own internal axis. The third mold 8 of the type
A two-split mold 9 for support that covers and integrates the entire body is set, and then the first and second molds 1,
An insulating material made of anti-tracking rubber or ethylene propylene rubber is injected into the space surrounded by the exit wire 1 and molded. According to the insulating member mold part 10 of the drawing line manufactured in this way, the second
As shown in the figure, each of the parts 11 and 12 has a smooth surface without vertical lines, and can be made to be in close contact with the grid line 1 throughout the rest period.
