本考案はアレスタに係り、特にアレスタ素子に
モールドを施したものに関する。[Detailed Description of the Invention] The present invention relates to an arrester, and particularly to an arrester element in which a mold is applied.
従来からアレスタ素子には外気との接触を防止

かし、この方法では大量生産するには多数の金型
を持たなくてはならず、大量生産能力に劣る欠点
がある。 Conventionally, arrester elements have been molded to prevent contact with the outside air and to prevent short circuits on the outer surface of the element. The conventional method for molding arrester elements is to fix the element in an EPR shrink tube and then directly mold it with epoxy resin. However, this method requires a large number of molds for mass production, and has the disadvantage of being inferior in mass production capacity.
本考案の目的は上記の欠点に鑑み、大量生産に
適し製作が容易なモールドアレスタを提供するに
ある。 SUMMARY OF THE INVENTION In view of the above drawbacks, an object of the present invention is to provide a molded arrester that is suitable for mass production and easy to manufacture.

ことを特徴とする。 The structure of the present invention to achieve this purpose is as follows:
One insert is attached to the lower part of a pre-manufactured molded case, and the arrester element is stored in the molded case in contact with the insert, and the other insert and the mode case lid having the rubber casting opening are attached to the other side. The present invention is characterized in that the insert is attached to the upper part of the mold case in a state in which it is in contact with the arrester element, and casting rubber is injected into the inside of the mold case from the rubber injection opening.
以下、本考案に係るモールドアレスタの一実施
例を図面に従つて説明する。 An embodiment of the molded arrester according to the present invention will be described below with reference to the drawings.
第１図乃至第４図は本考案に係るモールドアレ

する孔が設けられている。 FIG. 1 is a longitudinal cross-sectional view of a molded case. The molded case 12 is manufactured in advance and has an open end, into which a molded case lid 14 shown in FIGS. 2 and 3 is attached. The mold case lid 14 is provided with a rubber casting opening 16, an air vent 18, and a hole through which an arrester element insert 20 projects.
先ずモールドケース１２にアレスタ素子２２を

化する。 First, the arrester element 22 is placed in the mold case 12, and then the mold case lid 14 is attached.
Thereafter, as shown in FIG. 4, molding rubber 24 is injected from the rubber molding port 16 to fill the space between the mold case 12 and the arrester element 22 and fix them together. Note that the casting rubber 24 is in a liquid state at the time of injection and then hardens.

る効果がある。 According to this embodiment, since the mold case 12 is made in advance, there is an effect that mass production of mold arresters becomes possible. Since the casting rubber 24 is used, there is good adhesion between the arrester element 22 and the casting rubber 24, which has the effect of making it difficult for flashover to occur along the element surface. That is, the creeping flash value is increased compared to the conventional method using an EPR shrink tube. Additionally, unlike conventional direct molding, rubber casting is used, so there is no need to worry about cracks caused by the shape of the arrester. Furthermore,
This eliminates the need for an EPR contraction tube, which has the effect of reducing costs.
