Abstract

A sensor dome arrangement has a sensor dome and a housing wall, which is particularly a transmission wall. The sensor dome includes a sensor, dome contacts which are electrically connected to the sensor, and a dome housing. The dome housing has a first dome housing section in which the sensor is arranged, and a second dome housing section on or in which the dome contacts are arranged. A through-opening is made in the housing wall, and the sensor dome is attached to the housing wall such that at least one outer surface of the first dome housing section faces a first chamber which is adjacent to the sensor dome and an inner side of the housing wall, and such that the dome contacts face a second chamber which is adjacent to the sensor dome and an outer side of the housing wall.

First claim

1 - 20 . (canceled)

21 . A sensor dome arrangement, comprising:
a housing wall having an inner side, an outer side, and a dome through-opening formed therein; a sensor dome attached to said housing wall and projecting in said dome through-opening, said sensor dome having a dome housing with a first dome housing section and a second dome housing section, a sensor disposed in said first dome housing section and dome contacts disposed in said second dome housing section and electrically connected to said sensor; an outer surface of said first dome housing section facing toward a first chamber adjoining said sensor dome and an inner side of said housing wall, and said dome contacts facing toward a second chamber adjoining said sensor dome and an outer side of said housing wall.

22 . The sensor dome arrangement according to claim 21 , which comprises a seal, and wherein said sensor dome and said seal are attached to said housing wall to form a closure of said through-opening, and wherein said seal seals a closure between said first chamber and said second chamber.

23 . The sensor dome arrangement according to claim 21 , wherein said sealed closure forms an oil-tight seal.

24 . The sensor dome arrangement according to claim 23 , wherein said sealed closure forms a gas-tight seal.

25 . The sensor dome arrangement according to claim 21 , which further comprises a fastening device for fastening said sensor dome to said housing wall.

26 . The sensor dome arrangement according to claim 25 , wherein said dome housing has a connecting section formed between said first dome housing section and said second dome housing section, and which is fastened to form a seal to an outer side of said housing wall by way of said fastening device and said seal.

27 . The sensor dome arrangement according to claim 21 , wherein said dome housing comprises plastic or consists of plastic and said sensor is embedded in said plastic.

28 . The sensor dome arrangement according to claim 26 , wherein said connecting section is a flange, and wherein, with respect to a longitudinal direction of said sensor dome, said first dome housing section is formed on a first side of said flange and said second dome housing section is formed on a second side of said flange.

29 . The sensor dome arrangement according to claim 26 , wherein said seal has a sealing ring inserted into a groove formed on an outer side of said wall or in said connecting section.

30 . The sensor dome arrangement according to claim 28 , wherein said second dome housing section has a plug wall which proceeds from said flange and extends around said dome contacts, and is circumferentially closed in a ring shape.

31 . The sensor dome arrangement according to claim 21 , wherein said dome contacts are insulation-piercing contacts or blade contacts.

32 . The sensor dome arrangement according to claim 21 , wherein said sensor is disposed, with respect to a longitudinal direction of said sensor dome, at a greater distance from said seal than said dome contacts.

33 . The sensor dome arrangement according to claim 21 , which further comprises a control circuit having circuit contacts to be electrically connected to said dome contacts.

34 . The sensor dome arrangement according to claim 33 , wherein said dome contacts and said circuit contacts are configured to bring about an electrically conductive plug-in connection, formed as a plug-in terminal connection between one dome contact each and one circuit contact each.

35 . The sensor dome arrangement according to claim 33 , wherein one of the following is true:
said dome contacts are insulation-piercing contacts and said circuit contacts are blade contacts; or said dome contacts are blade contacts and said circuit contacts are insulation-piercing contacts.

36 . The sensor arrangement according to claim 21 , wherein:
said housing wall is formed with a plurality of through-openings, said sensor dome is one of a plurality of sensor domes, and said seal is one of a plurality of seals; each one of said sensor domes is attached to said housing wall at a respective one of said through-openings, such that at least one outer surface of said first dome housing section faces a first chamber that adjoins said sensor dome and an inner side of said housing wall, and such that said dome contacts face a second chamber that adjoins said sensor dome and an outer side of said housing wall; and the respective said sensor dome and said seal are attached to said housing wall to form a closure of the respective said through-opening, such that said seal seals the closure between said first chamber and said second chamber.

37 . The sensor dome arrangement according to claim 36 , wherein each said sensor dome is connected to a control circuit or is to be connected to said control circuit by way of an electrical plug-in connection.

38 . The sensor dome arrangement according to claim 21 , wherein said housing wall is an outer wall of a transmission, said first chamber is an interior of the transmission, in which gear wheels are located, and said second chamber is sealed overall by said first chamber.

39 . The sensor dome arrangement according to claim 33 , wherein said circuit contacts lead from said control circuit into a plug which has a plug base and a plug collar that proceeds from said plug base, wherein said plug collar is closed along a plug circumference, wherein said circuit contacts protrude beyond said plug base, and wherein said plug collar and said plug wall overlap one another in a plugging direction of the electrical plug-in connection.

40 . The sensor dome arrangement according to claim 33 , wherein said control circuit is an electronic circuit configured for performing open-loop and/or closed-loop control of a transmission.
