Case device with pressure compensation

Claim 1

A pressure-relieving casing arrangement, in particular for a pressure sensor, having the following features: a) a first casing (11, 5) for receiving at least one electrical component (10) is provided; b) the first casing (11, 5) has at least one electrically conductive contact element (18) which is connectable to the electrical component (10); c) a second casing (1, 2) is provided, which has at least one electrically conductive mating contact element (19) which is connected to at least one electrically conductive connecting element (24) positioned at least partially inside the second casing (1, 2); d) the contact element (18) of the first casing (11, 5) and the mating contact element (19) of the second casing (1, 2) are constructed so that they can be joined to one another in the manner of a plug-and-socket connection; e) at least one sealing element (29) is provided, which is arranged so that, when the plug-and- socket connection is made, the contact element (18) and the mating contact element (19) are positioned inside a space, sealed off by the sealing element (29), between the two casings (11, 5, 1, 2); f) the first casing (11, 5) has an opening (10) for pressure relief in the first casing (11, 5); characterized by the following features: g) the opening (6) of the first casing (11, 5) for the pressure relief in the first casing (11, 5) leads into the space, sealed off by the sealing element (29), between the two casings (11, 5, 1, 2); h) the second casing (1, 2) has an opening (3) which opens into the sealed space between the two casings (11, 5,1, 2) and which connects the interior (25) of the second casing (1, 2) to this sealed space; i) the second casing (1, 2) has an outlet (23) leading from the second casing (1, 2), which outlet (23) is connected to the interior of the second casing (1,2).
