controller

Abstract

A controller and a plug element comprising: an electronic module, a housing, the electronic module being arranged in an electronics compartment in the housing; a plug element having a seat element with a first side and a second side, the plug element There is also at least one electric wire leading from the first side of the support element to its second side, the potting material is arranged on the support element, so that the potting material completely surrounds the electric wire on the longitudinal section of the electric wire, the support element is composed of Made of a first material with a first coefficient of thermal expansion, the wire is made of a second material with a second coefficient of thermal expansion, the potting material is made of a third material with a third coefficient of thermal expansion, the plug element is received in the housing superior. The second material and the third material are selected such that the second and third thermal expansion coefficients are between 13 ppm / K and 30 ppm / K and in particular between 17 ppm / K and 24 ppm / K, and the first material is selected such that , so that the first coefficient of thermal expansion is between 13 ppm / K and 30 ppm / K and especially between 17 ppm / K and 24 ppm / K at least along two spatial directions.

Description

technical field [0001] The invention relates to a controller and the use of a plug element in the controller. Background technique [0002] In the motor vehicle field, controllers are used in a wide variety of applications. These controllers typically have an electronics compartment with sensitive electronics disposed therein. The control unit is often subjected to unfavorable conditions at its location in the vehicle. Among the unfavorable conditions are vibration loads, severe temperature fluctuations and often also the environment due to aggressive media such as exhaust gases, brake fluid, fuel and transmission oil. [0003] The electronics in the control unit must be permanently and reliably protected against all these influences, especially in contact with aggressive media, since otherwise individual electronic components or the entire electronics could be damaged. For this purpose, the electronic device is generally surrounded by a housing, wherein the power supply ...

Problems solved by technology

[0004] But here arises the following problem: most wires made of metal and the plastic surrounding them have very different coefficients of thermal expansion (CTE) from each other

However, the sealant is relatively expensive, while the reliable filling of the entire surrounding space with said sealant represents high demands on the production technology
