Abstract
Es wird ein Messfühler zur Bestimmung einer physikalischen Eigenschaft eines Messgases, insbesondere zur Bestimmung von Druck, Temperatur oder der Konzentration einer Gaskomponente, im Abgas von Brennkraftmaschinen angegeben, der ein Sensorelement (15), das auf einem anschlussseitigen Abschnitt (152) elektrische Kontaktstellen (16) trägt, und ein gegeneinander elektrisch isolierte Leiter aufweisendes Anschlusskabel (20) aufweist, dessen Leiter mit den Kontaktstellen (16) verbunden sind. Zur Gewinnung eines fertigungs- und montagetechnisch kostengünstigen Anschlusskabels (20) für das Sensorelement (15), das im Hochtemperaturbereich eine zuverlässige elektrische Signal- und Stromleitung und eine zuverlässige Isolation zwischen den elektrischen Leitern gewährleistet, weist das Anschlusskabel (20) mindestens eine hochtemperaturfeste, flexible Folie (21) auf und sind die Leiter von auf der mindestens einen Folie (21) verlaufenden Leiterbahnen (22) gebildet.A sensor is provided for determining a physical property of a measurement gas, in particular for determining pressure, temperature or the concentration of a gas component in the exhaust gas of internal combustion engines, comprising a sensor element (15) having electrical contact points (16) on a connection-side section (152) ), and having a mutually electrically insulated conductor exhibiting connection cable (20) whose conductors are connected to the contact points (16). To obtain a production and assembly technology cost-effective connection cable (20) for the sensor element (15), which ensures a reliable electrical signal and power line and reliable insulation between the electrical conductors in the high temperature range, has the connection cable (20) at least one high-temperature resistant, flexible Slide (21) and the conductors of on the at least one film (21) extending conductor tracks (22) are formed.
Description
Die Erfindung geht aus von einem Messfühler zur Bestimmung einer physikalischen Eigenschaft eines Messgases, insbesondere zur Bestimmung von Druck, Temperatur oder der Konzentration einer Gaskomponente im Abgas von Brennkraftmaschinen, nach dem Oberbegriff des Anspruchs 1.The The invention is based on a sensor for determining a physical Property of a sample gas, in particular for the determination of pressure, Temperature or the concentration of a gas component in the exhaust gas of Internal combustion engine, according to the preamble of claim 1.

Vorteile der ErfindungAdvantages of invention
Der erfindungsgemäße Messfühler mit den Merkmalen des Anspruchs 1 hat den Vorteil eines fertigungs- und montagetechnisch kostengünstigen Anschlusskabels für das Sensorelement, das im Hochtemperaturbereich zwischen 400–800°C eine zuverlässige elektrische Signal- und Stromleitung und eine zuverlässige Isolation zwischen den elektrischen Leitern gewährleistet. Das Anschlusskabel kann beliebig geführt und gebogen werden, was die Montage wesentlich erleichtert, und gleicht selbsttätig thermische und/oder mechanische Ausdehnungen und Bewegungen aus. Darüber hinaus ermöglicht das Anschlusskabel eine flache Ausbildung des Kontaktierbereichs des Sensorelements, so dass ein das Sensorelement aufnehmendes Fühlergehäuse bauklein ausgeführt werden kann.Of the inventive sensor with The features of claim 1 have the advantage of a manufacturing and mounting technology cost-effective Connection cable for the sensor element, which in the high temperature range between 400-800 ° C a reliable electrical Signal and power line and a reliable one Ensuring insulation between the electrical conductors. The connection cable can be arbitrary and be bent, which facilitates the assembly, and equals self-acting thermal and / or mechanical expansions and movements. About that also allows the connection cable a flat configuration of the Kontaktierbereichs the sensor element, so that a sensor housing receiving sensor housing are made small construction can.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Messfühlers möglich.By in the further claims listed activities are advantageous developments and improvements of the claim 1 specified sensor possible.
