Title:
CLOSED COMPRESSOR
Document Type and Number:
Japanese Patent JP2988555
Kind Code:
B2
Abstract:
PURPOSE: To lower temperature by forming a threaded hole at the outer surface of a bracket through different metal, layering earth terminals which are provided respectively with the threaded hole of the different metal, and fix them by bolting for the decreased heat conductivity of the earth terminal part.
CONSTITUTION: A bracket 20 which is fixed at a sealed container 1 is provided with a threaded hole part 21, which is constituted of stainless steel 22 which is embedded by means of a helical insert process. Stainless steel 32 which is processed by means of the helical insert process is embedded in the threaded part 31 of an earth terminal 30. Therefore, the heat conductivity from the sealed container 1 to the earth terminal 30 is transmitted through the bracket 20, the stainless steel 22, a bolt 4, and the stainless steel 32, so it is possible to reduce a rise in the temperature of the earth terminal 32 because the heat conductivity can be decreased.
