Abstract

The invention relates to an electric compressor that extends along a longitudinal axis and comprises at least one casing housing at least: a mechanism for compression of a coolant fluid; a drive unitarranged inside the casing and that drives the compression mechanism; a module for control of the drive unit; at least one electric connector (16) intended to connect the control module electrically to an energy source outside the compressor; and a cover (13) comprising a metallic part (22) and a synthetic part (23) arranged one against the other along the longitudinal axis and traversed by the electric connector (16). The electric compressor is characterised in that at least one sealing device (28) is arranged between the metallic part (22) and the synthetic part (23), the sealing device (28)extending around an electric connector (16).

Description

technical field [0001] The field of the invention is that of compressors fitted to air-conditioning units of motor vehicles. The invention relates more particularly to a method for sealing an electric compressor, and in particular to an electrical connector providing the same. Background technique [0002] The air conditioning unit of a motor vehicle comprises a closed air conditioning circuit in which a coolant fluid flows. Continuously and in the direction in which the coolant fluid flows through it, the air conditioning circuit basically comprises a compressor, a condenser, an expansion chamber and an evaporator. [0003] The compressor includes an axially extending casing of generally cylindrical shape. The housing is equipped with an inlet opening through which fluid enters the housing interior at low pressure. Fluid then flows through the housing from the inlet opening towards the mechanism for compressing the coolant fluid. The outlet opening communicates with the...
