Electric compressor with a hermetic terminal

An electric compressor comprising:

• a compression assembly,
• an electric motor arranged to drive the compression assembly;
• a compressor housing forming hermetic accommodation of the electric motor and the compression assembly;
• and
• a hermetic terminal comprising:
• a terminal holder defining a cavity and forming part of the housing, wherein the cavity formed by the terminal holder being terminated by a circumferential edge of a sidewall welded into the compressor housing and thereby forming one single unit with the compressor housing,
• at least two electrically conductive terminal pins extending through the terminal holder and connected to the electric motor, and
• an insulative structure insulating the terminal pins from the terminal holder and having a surface exposed in the cavity,
• wherein the electric compressor further comprises a sealing element defining an enclosed space in the cavity,
• wherein the sealing element forms a base and an annular wall extending from the base and configured to extend into the cavity such that the annular wall is in contact with the sidewall, and
• wherein the sealing element comprises at least one annular ridge extending upwards from the base, the annular ridge extending about the annular wall outside the cavity.
