Definitions

  • the invention relates to an electrical contact element with the features mentioned in the preamble of claim 1.
  • Sensor elements are known which are exposed to high temperatures and vibration loads, such as can occur, for example, in the exhaust gas tract of motor vehicles.
  • the electrical leads to such sensor elements are considerable
  • connection points of the sensor elements to the electrical supply lines and their insulation layers must be effectively shielded against excessive temperatures.
  • high temperature-resistant metal sheathed cables which must have a certain minimum length, are usually used in lambda probes.
  • Conventional cables can only take over the electrical connection to a downstream evaluation unit from a certain distance to the high-temperature measuring location.
  • the connection point between the temperature-resistant metal jacket line and the conventional flexible cable line must, however, be completely sealed against external influences.
  • Another problem is that the length of the metal sheathed cable is too long, which in this case is at risk of vibration breakage.
  • the metal sheathed line must therefore be as short as possible due to the resulting vibration load, which is why, in addition to sealing against weathering and moisture, the highest possible temperature resistance of the connection point is necessary.
  • the object of the invention is to produce a tight and temperature-resistant connection between a metal sheathed line and flexible cable lines, which also has the lowest possible mass.
  • An elastomer seal ensures a sealed encapsulation of the connecting element that is resistant to temperatures of over 200 ° C.
  • the contact housing of the contact element must be able to withstand relatively high temperatures and can do so Purpose, for example, consist of a thermosetting plastic or a ceramic material. These materials also have the advantages of high rigidity and mechanical resilience and a relatively free three-dimensional design freedom. The mechanical properties can be further improved by fiber reinforcements.
  • the contour of the contact element can be cylindrical, but due to the free formability in the casting or injection molding process, it can also be designed in any other way, depending on the desired installation position or additional anchoring or fixing.

  • This insulation can be, for example, a ceramic powder insulation 6 or some other type of temperature-resistant insulation.
  • Such a ceramic powder insulation 6 has, in addition to the desired insulation effect, the favorable property of having a vibration-damping effect and thereby reducing the risk of breakage of the line 2 due to shocks, sudden impacts or vibrations.
  • the free length of the line 2 as the connection between the sensor element and the contact element 1 is to be made as short as possible, the minimum length being due to the maximum temperature resistance of the contact element 1 or the sealing elements made of elastomer material located thereon. given.

  • This chamfer 84 may have a slope of 15 degrees or more, for example.
  • the depth of the chamfer 84 is appropriate to be chosen moderately so that it is more than 5% of the diameter of the opening 80 to provide an effective insertion aid.
  • the opening 80 has a taper 82 which serves as a stop for the metal jacket line 4.
  • this taper 82 acts as a guide for the contact lugs 12 and 14, which are preferably slightly bent outwards before insertion, so that they are pushed into a defined position in the contact housing 62 when the metal jacket line 4 is inserted.
