AIRTIGHT TERMINAL

WIPO Patent Application WO/2019/230605

A1

Provided is an airtight terminal for on-vehicle electric compressors, in which no gasket need be used. The present invention is provided with: a metallic outer ring having a through hole which is provided for helical fastening and a sealing hole which is linearly disposed; a lead which is inserted in the sealing hole of the metallic outer ring; and an insulating material that seals the metallic outer ring and the lead. The metallic outer ring has a seal covering portion having elastic deformability, on a prescribed surface, of the metallic outer ring, to serve as a contact surface to which an external device is attached. The seal covering portion is provided so as to have an oval bund-like shape. Further, the sealing hole is disposed inside a region surrounded by the band-like section. When attached to an external device such as an airtight container of an electric compressor, the airtight terminal is helically fastened as a result of elastic deformation of the band-like seal covering portion having been pressed against an outer wall surface of the external device. At the same time, a terminal attachment hole provided in the outer wall surface of the external device is disposed inside the oval band of the seal covering portion so that the inside of the oval band can be airtightly separated from the outside.
