Abstract:
1. A housing for receiving an electronic circuit ( 4 ) made from a plurality of components ( 5 ) comprising a carrier plate ( 7 ) and a housing cover ( 8 ) including a circumferentially enclosing wall ( 9 ) disposed on the carrier plate ( 7 ) and a cover part ( 10 ) disposed on the wall ( 9 ), wherein the cover part ( 10 ) lies opposite the carrier plate ( 7 ), a volume compensation element ( 11 ) is attached on the carrier plate ( 7 ) in an interior ( 12 ) of the housing cover ( 8 ) which is enclosed in a pressure-tight manner with respect to an external atmosphere, the volume compensation element ( 11 ) is elastically formed such that there is a variable volume for compensation of pressure fluctuations occurring in the interior ( 12 ), which variable volume is due to a change in position of the volume compensation element ( 11 ) with respect to the carrier plate ( 7 ), and a gap between the volume compensation element ( 11 ) and the carrier plate ( 7 ) is connected to the external atmosphere, wherein an attachment section ( 16 ) of the volume compensation element has a volume element ( 26 ) on a side of the attachment section facing towards the electronic circuit ( 4 ), wherein the volume element protrudes into gaps between the electronic components ( 5 ) and wherein the wall ( 9 ) and serve to reduce the air volume present in the interior ( 12 ), and wherein the volume compensation unit ( 11 ) is formed of an outer attachment section ( 16 ) and an inner membrane section ( 17 ) which are circumferentially connected to each other by a resilient connecting part ( 18 ).
