Problems solved by technology

However, due to the material of the contact element and the connecting cable, welding methods that generate fusion cannot be used or cause weakening of the material, so that the detector can no longer meet the requirements during operation

Embodiment Construction

[0041] figure 1 A schematic cross-sectional view of the detector 10 is shown. Sensor 10 is designed, for example, as an air intake sensor. The air intake sensor is used to control the air-fuel mixture of the internal combustion engine, so that by measuring the concentration of the oxygen component in the exhaust gas, it can adjust the mixture as stoichiometric as possible, so that the emission of harmful substances can be minimized through the most optimal combustion. Within the scope of the invention, the measurement space can therefore be an exhaust system of the internal combustion engine. The basic structure and mode of function are described, for example, in Konrad Reif (published): Sensors in Motor Vehicles, first edition 2010, pp. 160-165. Using broadband air mass sensors, in particular planar broadband air mass sensors, it is possible, for example, to determine the oxygen concentration in the exhaust gas over a large area and thus to draw conclusions about the air-fu...

Abstract

The invention disclsoes a method used for manufacturing a detetcor especially a sensor, and the method is used for manufacturing at least one characteristic of measured gas, especially used for verifying the gas composition or the temperature of the measured gas. The method comprising the following steps: at least one sensor element is disposed in a detector housing, and is connected with at least one contact element; at least one connecting cable is provided; the connecting cable is connected with the contact element in a shape-locking connection or in a force-locking connection; the connecting cable is connected with the contact element material in a locked manner. The invention also relates to the above mentioned detector, especially the sensor. The detector comprises a detector housing and at least one sensor element in the detector housing, and the sensor element is connected with at least one contact element. The contact element is in the shape-locking connection or the force-locking connection with the connecting cable, and the contact element and the connecting cable are connected together with the help of the welding material.

Description

Background technique [0001] Various detectors and methods for determining at least one property of a measurement gas in a measurement gas space are known from the prior art. Basically any physical and / or chemical characteristic of the gas can be measured here, one or more characteristics can be detected. The invention will be described below in particular with regard to the qualitative and / or quantitative detection of certain gas components of the measurement gas, in particular with regard to the detection of the oxygen component in the measurement gas. The oxygen content can be detected, for example, as partial pressure and / or as a percentage. Instead or in addition, however, other characteristics of the measurement gas can also be detected, for example the temperature of the measurement gas. [0002] Such a sensor can be designed, for example, as a so-called air intake sensor, as is known, for example, from Konrad Reif (published): Sensors in Motor Vehicles, first edition ...
