Abstract

The invention relates to a fastening arrangement for a sensor (2) on a receptacle (1), with a receptacle through-hole (13, 13a) leading to the interior (12) of the receptacle (1), a receptacle stop (16), and a sensor housing (20-23) exhibiting a sensor device (28) and a circumferential housing stop (27). To advantageously fasten the sensor to the receptacle a pressure screw (4) is provided, which exhibits a pressure screw through-hole (41), which receives the housing (20, 23); and exhibits a pressure area (43) used in pressing the housing stop (27) against the receptacle stop (16) to fasten together the sensor housing (20, 23) and the receptacle (1).

Claims

1. A fastening arrangement for a sensor (2) on a receptacle (1) with

a receptacle through-hole (13, 13a) leading to the interior (12) of the receptacle (1) and with a receptacle stop (16), and

a housing (20-23) for the sensor (2), with a sensor device (28) and a circumferential housing stop (27),

wherein

a pressure screw (4) with a pressure screw through-hole (41) encompasses the housing (20, 23) and exhibits a pressure area (43) for pressing the housing stop (27) against the receptacle stop (16) in order to fasten together the sensor housing (20, 23) and the receptacle (1), where the pressure screw (4) engages in screw-like fashion with a thread (13, 13a) of the receptacle (1) during the fastening process.

2. A fastening arrangement according to claim 1 for a pressure sensor (2) serving as the sensor device on the receptacle (1) with

a pressure sensor housing (2) serving as the sensor housing, which receives the pressure sensor device (28) serving as sensor device and which exhibits an at least partially circumferential housing stop (27),

a fastening device (14) on the receptacle (1), which fastening device (14) exhibits a through-hole (13, 13a) serving as receptacle through-hole to the interior (12) of the receptacle (1) and exhibits the receptacle stop (16), as well as a thread (15) for securing the housing (20, 23) to the fastening device (14), and

a fastening means (4) for securing the housing stop (27) to the receptacle stop (16),

wherein

the thread (15) takes the form of an inner thread (15) in the receptacle through-hole (13, 13a), and

the fastening means takes the form of the pressure screw (4) exhibiting an outer thread (42) for engaging with the inner thread (15) and exhibiting a pressure screw through-hole (41) running in the axial direction for at least partial reception of the housing (20, 23) and exhibiting a pressure area (43) on its front end for pressing the housing stop (27) against the receptacle stop (16) to establish a secure connection.

3. A fastening arrangement according to claim 2, in which the inner thread (15) is designed for a screw engagement with the pressure screw (4) in an outwardly directed section of the receptacle through-hole (13) or the bushing through-hole (13a).

4. A fastening arrangement according to claim 1, in which the receptacle stop (16) is designed as a bushing in the receptacle (1).

5. A fastening arrangement according to claim 1, in which the pressure screw (4) exhibits the central axial pressure screw through-hole (41) such that the pressure screw (4) rotates around the housing (20, 23) when the sensor (2, 20, 23) is secured to the receptacle (1).

6. A fastening arrangement according to claim 5, in which the housing (20, 23) is sealed with a circumferential seal (24) vis-a-vis the receptacle through-hole (13, 13a), where for the purpose of screwing the pressure screw (4) is designed for easily-rotating, axial insertion of the housing (20, 23) into the receptacle through-hole (13).

7. A fastening arrangement according to claim 1, in which the housing stop (27) protrudes from the outside of the housing (20, 23) and exhibits a housing stop area (27a) pointing in the direction of the receptacle (1) in order to limit the insertion depth of the housing (20, 23) into the receptacle through-hole (13, 13a) through abutment with the receptacle stop (16).

8. A fastening arrangement according to claim 1, in which the receptacle stop (16) is located inside the receptacle through-hole (13) or the bushing through-hole (13a).

9. A fastening arrangement according to claim 1, in which the housing stop (27) and/or another housing stop which projects laterally from the housing (20, 23) exhibits a stop area that faces away from the receptacle (1) and serves as a counter-stop for the pressure area (43) of the pressure screw (4).

10. A fastening arrangement according to claim 1, in which the sensor device (28) is a pressure sensor with an outer diameter of less than 115 mm, particularly less than or equal to 30 mm.

11. A fastening arrangement according to claim 1, in which the housing (20, 23) in its section that is to be inserted into the receptacle through-hole (13, 13a) exhibits an outer diameter that is less than 115 mm, particularly less than or equal to 30 mm.

12. A fastening arrangement according to claim 1, in which the housing (20, 21) has an external housing stop (5) which projects outward from the housing (20, 21) in a section that is located on the side of the pressure screw (4) that faces away from the receptacle (1).
