Abstract

A sensor device includes a resin inner housing which has an accommodating space therein and in which an opening is provided, an externally exposed part which is disposed to cover the opening or pass through the opening and of which at least a part is exposed to the outside of the inner housing, and a metal outer housing which is positioned outside the inner housing and accommodates the inner housing and covers the inner housing. When a sealing treatment is performed between the inner housing and the externally exposed part, the accommodating space is sealed off from a space outside the inner housing. When a cut-off part is provided in the outer housing at a position corresponding to the part exposed to the outside of the inner housing of the externally exposed part, the part of the externally exposed part is also exposed to the outside of the outer housing.

First claim

What is claimed is:

1. A sensor device comprising:
an inner housing made of resin which has an accommodating space therein and in which an opening is provided;
an externally exposed part which is disposed to cover the opening or pass through the opening and at least a part of the externally exposed part is exposed to the outside of the inner housing; and
an outer housing made of metal which is positioned outside the inner housing and accommodates the inner housing and covers the inner housing,
wherein, a sealing treatment is performed between the inner housing and the externally exposed part, and the accommodating space is sealed off from a space outside the inner housing, and
wherein, a first cut-off part is provided in the outer housing at a position corresponding to the part exposed to the outside of the inner housing of the externally exposed part, the at least a part of the externally exposed part is also exposed to the outside of the outer housing.

2. The sensor device according to claim 1 ,
wherein the outer housing is formed by combining at least two or more divided segments.

3. The sensor device according to claim 2 ,
wherein each of the two or more divided segments is formed of a press molded product of a metal plate member.

4. The sensor device according to claim 1 ,
wherein a heat insulating layer is positioned between the outer housing and the inner housing.

5. The sensor device according to claim 2 ,
wherein a heat insulating layer is positioned between the outer housing and the inner housing.

6. The sensor device according to claim 3 ,
wherein a heat insulating layer is positioned between the outer housing and the inner housing.

7. The sensor device according to claim 1 , further comprising:
a fixed member made of metal that defines a screw hole for installing the sensor device by screw fastening,
wherein the fixed member is buried in the inner housing so that the screw hole is exposed to the outside of the inner housing, and
wherein, a second cut-off part is provided at a position corresponding to the screw hole on the outer housing, and the screw hole is also exposed to the outside of the outer housing.

8. The sensor device according to claim 2 , further comprising:
a fixed member made of metal that defines a screw hole for installing the sensor device by screw fastening,
wherein the fixed member is buried in the inner housing so that the screw hole is exposed to the outside of the inner housing, and
wherein, a second cut-off part is provided at a position corresponding to the screw hole on the outer housing, and the screw hole is also exposed to the outside of the outer housing.

9. The sensor device according to claim 3 , further comprising:
a fixed member made of metal that defines a screw hole for installing the sensor device by screw fastening,
wherein the fixed member is buried in the inner housing so that the screw hole is exposed to the outside of the inner housing, and
wherein, a second cut-off part is provided at a position corresponding to the screw hole on the outer housing, and the screw hole is also exposed to the outside of the outer housing.

10. The sensor device according to claim 4 , further comprising:
a fixed member made of metal that defines a screw hole for installing the sensor device by screw fastening,
wherein the fixed member is buried in the inner housing so that the screw hole is exposed to the outside of the inner housing, and
wherein, a second cut-off part is provided at a position corresponding to the screw hole on the outer housing, and the screw hole is also exposed to the outside of the outer housing.

11. The sensor device according to claim 5 , further comprising:
a fixed member made of metal that defines a screw hole for installing the sensor device by screw fastening,
wherein the fixed member is buried in the inner housing so that the screw hole is exposed to the outside of the inner housing, and
wherein, a second cut-off part is provided at a position corresponding to the screw hole on the outer housing, and the screw hole is also exposed to the outside of the outer housing.

12. The sensor device according to claim 6 , further comprising:
a fixed member made of metal that defines a screw hole for installing the sensor device by screw fastening,
wherein the fixed member is buried in the inner housing so that the screw hole is exposed to the outside of the inner housing, and
wherein, a second cut-off part is provided at a position corresponding to the screw hole on the outer housing, and the screw hole is also exposed to the outside of the outer housing.

13. The sensor device according to claim 1 ,
wherein the externally exposed part is at least one of a detection part, a display part, an operation part, and a cable drawing out part.

14. The sensor device according to claim 2 ,
wherein the externally exposed part is at least one of a detection part, a display part, an operation part, and a cable drawing out part.

15. The sensor device according to claim 3 ,
wherein the externally exposed part is at least one of a detection part, a display part, an operation part, and a cable drawing out part.

16. The sensor device according to claim 4 ,
wherein the externally exposed part is at least one of a detection part, a display part, an operation part, and a cable drawing out part.

17. The sensor device according to claim 5 ,
wherein the externally exposed part is at least one of a detection part, a display part, an operation part, and a cable drawing out part.

18. The sensor device according to claim 6 ,
wherein the externally exposed part is at least one of a detection part, a display part, an operation part, and a cable drawing out part.
