The invention relates to a simple high-temperature-resistant differential connector and an assembling method, belonging to the technical field of electrical transmission, comprising a connecting shell, a ceramic base, a ceramic cover, a pin, a sheath, a tail cover and a double-core armored cable, Among them, the material of the sheath, the tail cover and the connecting shell are all Inconel600 alloy, and the material of the ceramic cover plate and the ceramic base are high-purity alumina ceramics. The invention adopts the method of interference fit to assemble the pin and the insulating ceramic. The material of the pin is Kovar alloy. The thermal expansion coefficient of the alloy material is basically the same as that of the high-purity alumina ceramic at high temperature, and both are Linearity can ensure the airtightness of the connector at high temperature; the present invention adopts high-purity alumina ceramics with high impedance at high temperature and linear expansion coefficient as insulating material, and the temperature resistance is as high as 1000 ℃, and it can be used at temperatures as high as 600 ℃. Long service in extreme environments. |
