Abstract

A sensor housing (1) including a longitudinal axis (2), a clamping area (3) surrounding the longitudinal axis (2) and a recess (4) in the clamping area (3) is described, the recess (4) running in circumferential direction. In such a sensor housing a recess in the clamping area (3) should be provided with low production costs. To this end the recess (4) is formed between a part 6 of the housing (1) and a locking element (5) fixed to the housing (1).

First claim

What is claimed is:

1. A sensor housing comprising
a longitudinal axis,
a housing part surrounding the longitudinal axis and having an axially-facing clamping surface,
an extension surrounding the longitudinal axis and extending from the axially-facing clamping surface,
a circumferential groove extending around the extension, the groove being axially-spaced from the axially-facing clamping surface, and
a locking element located in the groove,
wherein a circumferential recess is formed between the axially-facing clamping surface and the locking element.

2. The sensor housing according to claim 1 , wherein the extension has a cross section area smaller than a cross section area of the housing part, wherein the locking element is fixed to the extension.

3. The sensor housing according to claim 2 , wherein the extension is arranged coaxially to the longitudinal axis.

4. The sensor housing according to claim 3 , wherein the locking element at least partly surrounds the extension.

5. The sensor housing according to claim 4 , wherein the extension is of cylindrical form.

6. The sensor housing according to claim 4 , wherein the extension extends perpendicularly from the axially-facing clamping surface of the housing part.

7. The sensor housing according to claim 4 , wherein the locking element is a clip element which is snapped into the groove.

8. The sensor housing according to claim 3 , wherein the extension is of cylindrical form.

9. The sensor housing according to claim 3 , wherein the extension extends perpendicularly from the axially-facing clamping surface of the housing part.

10. The sensor housing according to claim 3 , wherein the locking element is a clip element which is snapped into the groove.

11. The sensor housing according to claim 2 , wherein the extension is of cylindrical form.

12. The sensor housing according to claim 2 , wherein the extension extends perpendicularly from the axially-facing clamping surface of the housing part.

13. The sensor housing according to claim 2 , wherein the locking element is a clip element which is snapped into the groove.

14. The sensor housing according to claim 13 , wherein the clip element is E-shaped.

15. The sensor housing according to claim 2 , wherein the locking element is a locking washer.

16. The sensor housing according to claim 2 , wherein a working section of the sensor housing extends from the extension.

17. The sensor housing according to claim 16 , wherein the working section has a cross section area smaller than that of the extension.

18. The sensor housing according to claim 16 , wherein the working section comprises a threaded portion.

19. The sensor housing according to claim 1 , wherein the locking element is a planar clip element.

20. The sensor housing according to claim 1 , wherein the locking element is a locking washer that encircles the extension.
