Definitions

  • cases accommodating a printed circuit board whose edges match an internal contour of a housing defined jointly by a body and a cover of the case. Furthermore, the sealing of the case is maintained thanks to a seal interposed between the body and the cover.
  • the invention aims to at least partially overcome the above drawbacks and to this end proposes a housing, in particular a compressor housing, said housing comprising first and second parts jointly defining a first housing, said housing further comprising a plate, one or more supports for holding said plate and a seal, said plate and said holding support(s) being arranged in said first housing, said seal being located between said first and second parts, said seal comprising one or more protrusions directed towards the inside of the first housing and pressing on said plate at a contour of said plate to apply said plate to said holding support(s).
  • the protrusion(s) provided on the seal contribute to reinforcing the retention of said plate in the housing.
  • the risks of vibrations of free edges of the plate are limited without having to multiply specific plate fixing members, such as screws or rivets.
  • the protrusions have a limited surface reinforcing the effectiveness of the retention.
  • the invention also relates to a compressor comprising a housing as presented above.
  • the invention relates to a housing. It will find its applications, for example, in a motor vehicle as a compressor of a refrigerant fluid of a thermoregulation system of zones of the vehicle, such as a passenger compartment of the vehicle, and/or of components of the vehicle, such as an electrical energy storage device, an electric machine for motorizing the vehicle and/or an electronic device for controlling said electric machine.
  • said housing accommodates an electric motor and a compression system driven by said motor.
  • Said housing comprises first and second parts 2, 4 jointly defining a first housing, not visible in this figure.
  • the first part 2 forms a body of the housing and the second part 4 forms a cover of said housing.
  • said housing for example said body, advantageously comprises a second housing 6 intended to accommodate said electric motor and/or said compression system, not illustrated.
  • Said body also comprises inlet/outlet pipes 7 for the refrigerant fluid intended to enter said second housing 6, at low pressure, and to exit therefrom, at high pressure.
  • Said second housing 6 is intended to be closed by another cover, not shown, of said housing.

  • Said housing further comprises a plate 8.
  • Said plate 8 is arranged in said first housing 10.
  • Said plate 8 is formed, for example, of a printed circuit board carrying various electronic components used, in particular, for controlling the drive motor located in said second housing 6.
  • a bottom of the first housing 10 advantageously forms a partition separating the first and second housings 6, 10.
  • Said second housing 6 is preferably configured so that the refrigerant circulating in said second housing 6 is in contact with said partition, which makes it possible to evacuate at least part of the heat released by said electronic components located in said first housing 10.
  • Said housing further comprises a seal 12, located between said first and second parts 2, 4, to ensure a sealed closure of said first housing 10.
  • Said seal 12 comprises, for example, a metal core coated at least partially with an elastomeric material.
  • said housing comprises one or more supports 14 for holding said plate 8. Said holding support(s) 14 are arranged in said first housing 10.
  • said sealing joint 12 comprises one or more protrusions 22, here two, directed towards the inside of the first housing 10.
  • said protrusion or protrusions 22 press on said plate 8 at the level of a contour 24 of said plate 8 to apply said plate 8 to said holding support or supports 14.
  • the holding of the plate 8 is reinforced, which makes it possible to limit the risks of vibrations of the free edges of the plate 8 without having to multiply specific members for fixing the plate, such as screws or rivets.
  • the protrusions 22 have a limited surface area. Indeed, it is understood that the said holding support(s) 14 are located along said contour 24 of the plate 8.
  • the contour 24 of the plate 8 is free over at least part of said contour 24, in particular at the level of said protrusions 22.
  • the contour 24 of the plate 8 is free over its entirety and/or fits a wall 28 of said first housing 10, with a slight clearance.
  • said protrusion(s) 22 bear on said plate 8 and said plate 8 bears on the holding support(s) 14 in respective bearing zones.
  • the support zone(s) of the plate 8 on the holding support(s) 14 and the support zone(s) of the protrusions 22 on the plate 8 are located in line with each other.
  • the plate 8 is thus sandwiched between said protrusion(s) 22 and the holding support(s) 14.
  • said housing comprises one or more fixing supports 14' for said plate 8.
  • Said fixing support(s) 14' are located, in particular, along said contour 24 of the plate 8.
