摘要:
A contact element, in particular for making electrical contact to a sensing element of a gas sensor. The contact element has at least one connecting conductor, guided in a metal-sheathed line and contacted to at least one flexible connecting line. A connecting point between the at least one connecting conductor and the at least one connecting line is arranged in a contact housing that allows sealed and temperature-resistance contacting. The contact housing has at least one connecting element that is immovably joined to the at least one connecting line and may be contacted to the at least one connecting conductor. The at least one connecting element is arranged with an interference fit and in a form locking manner in the contact housing. The contact housing is enclosed by a temperature-resistant protective sleeve, which is joined directly to the metal-sheathed line (20,22) and to the at least one connecting line (20, 22).
摘要:
A gas sensor having a sensor element which is immobilized in gas-tight fashion in a metal housing. The gas sensor has a double-walled protective tube with an outer protective sleeve and an inner protective sleeve, each of which possesses openings for the entry and/or exit of gas. The inner protective sleeve forms a gas space into which the sensor element projects with a section at the measurement-gas end. The outer protective sleeve is a sleeve having a closed enveloping surface, the openings for the entry and/or exit of gas being arranged in the cavity at the end face of the sleeve. The gas space formed by the inner protective sleeve has, perpendicular to the extension direction of the sensor element, a rectangular cross section.

A measuring sensor, in particular for determining the oxygen content in exhaust gases of internal combustion engines, having a sensor element fixed in gastight fashion in a metal housing (14) and having a sealing flange (60) mounted on the housing (14) and resting on a sealing seat (76) embodied in an exhaust system (11). A union nut (80) is guided over onto the housing (14) and can be screwed into a thread (78) of an opening (70) provided in the exhaust system (11) and presses the sealing flange (60) against the sealing seat (76). The housing (14) has a housing part (12) on the side toward the gas to be measured and a further housing part (13) on the side toward the connection, and the sealing flange (60) is disposed on the housing part (13) on the side toward the connection and is shaped from the material of the housing part (13) on the side toward the connection.
摘要:
The invention relates to a measuring instrument, particularly an electrochemical measuring sensor, having a sensor element arranged at a measuring point, which sensor element can be connected via electrical connecting leads with an evaluating circuit removed from the measuring point, with the electrical connecting leads being guided so as to be protected against external influences, especially against high temperature influences, at least in the proximity of the measuring point. At its end facing away from the sensor element (12), a protective device (24) receiving the electrical connecting leads (22) is provided with a connecting device (30) which can be connected to a connecting lead (54, 56) to the evaluating circuit.
摘要:
Multiple contacts are provided in an electrical contacting arrangement of a sensor element, and the sensor element has a connection-side section with contact points, or contact pads, which are each integrally bonded to a corresponding contact. Each of the multiple contacts, at least on the section in contact with the contact point on the sensor element, has a layer by which the integral bond is formed between the contact and the contact point on the sensor element. The contacts are joined to the corresponding contact points on the sensor element by diffusion soldering or diffusion welding. Each contact has a curved intermediate section which compensates for thermal and/or mechanical expansion and movements.

A sensor, particularly for determining the oxygen content in exhaust gasses of internal combustion engines, includes sensor element which is fixed in a metallic housing and a sealing flange which is integrally formed on the housing and rests on a sealing seat which is formed on an exhaust system. The sealing flange has two ring elements which are integrally formed on the housing and each have an inclined sealing surface, a hollow space being formed between the two ring elements inside the housing.

The circuit device has a contact element, which electrically connects a wave guide (1) with a conductor strip (2). To avoid mechanical stresses due to thermal expansion the contact element is a pre-stressed prefabricated leaf spring having reproducible properties, which is bonded at one contacting area to the wave guide (1) or the conductor strip (2) by electrically conducting adhesive or glue, while a sliding contact is provided on the conductor strip (2) or the wave guide (1) at the other contacting area. The prefabricated leaf spring is preferably a MIGA leaf spring precisely made by UV depth lithography and multiplayer galvanic methods in a batch production process.
