ものである。 By the way, for example, in Utility Model Publication No. 49-26474,
After forming a silver-baked plating layer on the outer peripheral wall of the porcelain insulator tube, a metal mounting bracket is inserted into the outer periphery of the porcelain insulator tube to connect the outer peripheral wall of the porcelain insulator tube and the inner peripheral wall of the mounting bracket. A technical idea has been disclosed in which the mounting fitting is connected to the porcelain insulator tube by soldering, but in the case of such a bushing, the silver baked plating layer is formed directly on the outer peripheral wall of the porcelain insulator tube. Because of this, the bonding strength of the plating layer to the insulator tube is weak. Therefore, even if the mounting bracket is connected to the porcelain insulator tube by soldering through the silver-baked plating layer, the bonding strength of the plating layer to the insulator tube is weak. It is not possible to obtain sufficient bonding strength to the porcelain pipe.

も非常に高くなるのである。 Therefore, the adhesion layer 5 serves as a binder to firmly adhere the adhesion layer 6 to the porcelain insulator tube 2, and copper sulfide powder is used to form the adhesion layer 5. By using a paste made by mixing clay with clay, the porcelain insulator tube 2 can be baked at a low temperature and in an oxidized state. The viscosity of copper sulfide decreases,
Since both of them in a mixed state deeply penetrate inside the outer wall of the porcelain insulator tube 2 and become vitrified, the adhesive strength of the adhesive layer 6 formed on the adhesive layer 5 to the porcelain insulator tube 2 increases. becomes very high,
Therefore, the bonding strength between the porcelain insulator tube 2 and the metal mounting member 3, which are brazed together via the adhesive layer 6, is also extremely high.

After forming the adhesive layer 6 made of silver produced by thermal decomposition of silver carbonate, the silver solder layer 8 is formed on the porcelain insulator tube 2 and the metal mounting member 3.
The wettability of the brazing filler metal 7 melted between the
Furthermore, since the silver solder layer 8 contains an antioxidant, the porcelain insulator tube 2 is prevented from oxidizing the adhesive layer 6 during brazing with the brazing filler metal 7.
This makes it possible to prevent a decrease in the bonding strength between the metal mounting member 3 and the metal mounting member 3.

Therefore, there is no need to use porcelain fired at a high temperature as the porcelain insulator tube 2.

のである。(Effects of the Invention) As described above, according to the method of manufacturing a bushing according to the present invention, the adhesive layer naturally plays the role of a binder for firmly adhering the adhesive layer to the porcelain insulator tube. In order to form such an adhesion layer, a paste made by mixing clay with copper sulfide is used, so baking onto the porcelain insulator tube is done at a low temperature and under oxidized conditions. Moreover, when baking the porcelain insulator tube,
Since both clay and copper sulfide penetrate deeply into the outer wall of the porcelain insulator tube and become vitrified, the adhesion strength of the adhesive layer formed on the adhesive layer to the porcelain insulator tube is extremely high. Therefore, the bonding strength between the porcelain insulator tube and the metal mounting member which are brazed together through such an adhesive layer becomes extremely high.
