Patent ID: 8891585

Claim:
A heating electrode assembly for a crystal growth furnace, the crystal growth furnace including a furnace wall and a heater disposed in the furnace wall, said heating electrode assembly comprising: a heat insulation board unit that is adapted to be disposed between the furnace wall and the heater, that includes a first surface to be disposed so as to face the furnace wall, and a second surface to be disposed so as to face the heater, and that is formed with a through hole extending through said first surface and said second surface; an electrode unit that includes an electricity input portion which is adapted to be mounted to the furnace wall, a post portion which is axially disposed in said through hole of said heat insulation board unit, and an abutment flange which is connected to said post portion, which is disposed adjacent to said second surface of said heat insulation board unit, and which is adapted for connecting to the heater; an electrical insulating unit that includes an electrical insulating tubular sleeve which is axially disposed in said through hole and which surrounds said post portion of said electrode unit, and an electrical insulating pad which is clamped between said abutment flange of said electrode unit and said second surface of said heat insulation board unit; and wherein said electrical insulating unit further includes a pair of insulating lining parts that are complementary in shape and that are assembled to form a cylindrical insulating lining which is axially disposed in said through hole, and which is fitted between said electrical insulating tubular sleeve and said post portion of said electrode unit.
