Appl. No.:

10/822417

Inventors:

Norman Hahn - Anderson SC, US
Grady Prewitt - Anderson SC, US
Craig Magera - Simpsonville SC, US

Assignee:

Robert Bosch GmbH - Stuttgart

International Classification:

G01N 27/407

US Classification:

204428, 204424, 439260

Abstract:

An insulation bushing assembly for use with an exhaust gas sensor. The insulation bushing assembly includes an insulation bushing having a passageway defining a surface, and a contact plate assembly having a contact plate coupled with the insulation bushing. A resilient member extends from the contact plate and into the passageway. The resilient member is engageable with the surface of the passageway such that the member is deflected by the surface from an undeflected position with respect to the contact plate to a deflected position with respect to the contact plate to retain the contact plate assembly in engagement with the bushing.

US Classification:

73 2331, 73 3105, 204424

Abstract:

A gas sensor, whose purpose is to determine a physical property of a measuring gas, e. g. , to determine the concentration of a gas component or the temperature of an exhaust gas. The gas sensor includes a sensor element arranged in a metal housing which is sealed by at least one sealing element arranged in a metal receptacle. The metal receptacle is affixed to the housing. The sealing element surrounds the sensor element in a centered position along its longitudinal extension L or on its half facing the measuring gas.

International Classification:

H01R013/40

US Classification:

439/587000

Abstract:

A replacement kit for replacing an electrical device coupled to a vehicle via a plurality of vehicle lead wires. The replacement kit includes a replacement electrical device, a plurality of lead wires extending from the replacement electrical device, and a housing assembly for protecting a spliced connection formed with the lead wires to create an electrical connection between the electrical device and the vehicle. The housing assembly includes a base having a plurality of individually isolated bores extending therethrough. Each bore is capable of housing a spliced connection of a respective vehicle lead wire and a respective replacement electrical device lead wire, and each bore has therein a plurality of seal rings to form a substantially water-tight seal around the associated portion of the spliced connection. The housing assembly also includes a cap secured to the base. Preferably, the electrical device and the replacement electrical device are oxygen sensors.

G01N 27/416

Abstract:

A system configured to detect defects in a first oxygen sensor is disclosed. The system is configured to detect defects in a first oxygen sensor. The system includes an X-ray imaging device configured to capture a production X-ray image of the first oxygen sensor and an electronic processor configured to use a trained oxygen sensor defect detection model to identify a defect of the first oxygen sensor by producing a pseudo X-ray image by simulating a projection of a fan beam through CT data of a second oxygen sensor. The electronic processor is also configured to measure, via the trained oxygen sensor defect detection model, a fan-beam distortion in the production X-ray image; select, via the trained oxygen sensor defect detection model, the pseudo X-ray image based on the fan-beam distortion; perform a comparison, via the trained oxygen sensor defect detection model, of the production X-ray image to the pseudo X-ray image; and, classify, based on the comparison, the production X-ray image as representing an improperly assembled oxygen sensor.

International Classification:

G01N 33/00
G01M 15/10

US Classification:

73 2331

Abstract:

A gas sensor includes a sensor housing and a sensing element located within the sensor housing. The sensing element has a distal end and defines an axis. The gas sensor also includes a sensor protection device coupled to the sensor housing and at least partially surrounding the distal end of the sensing element. The sensor protection device includes a first member coupled to the housing, the first member having a generally rectangular cross-sectional shape in a plane perpendicular to the axis. The first member includes a gas inlet and a gas outlet. The sensor protection device also includes a second member coupled to the housing.

Assignee:

Robert Bosch GmbH - Stuttgart

International Classification:

G01N 33/00

US Classification:

73 232

Abstract:

A gas sensor includes a gas sensing element positioned at least partially within a body and exposed at a first end to measure a gas in contact with the first end. The gas sensing element defines an axial direction. A flange extends from the body in a direction transverse to the axial direction. The flange has a first side facing toward the first end and a second side facing toward a remote end of the gas sensor. An O-ring is configured to sealingly position the gas sensor within a bore. An insertion portion of the gas sensor is defined by a wall and configured to hold the O-ring. The wall of the insertion portion is spaced a distance from the body at an axial position of the O-ring to provide a gap therebetween.

Abstract:

A gas sensor includes a sensor housing and a sensing element located within the sensor housing. The sensing element defines an axis. The sensing element has a distal end extending from the sensor housing. The gas sensor further includes a sensor protection element coupled to the sensor housing and at least partially surrounding the distal end of the sensing element. The sensor protection element includes a tube having a conical portion, and a gas inlet located on the tube, the gas inlet spaced from the axis. The gas inlet is shaped to direct gas into the tube to induce a vortex gas flow within the conical portion of the tube.
