Embodiment Construction

[0032] exist Figure 1a An embodiment of a device ( 600 ) is shown in , with an elastic sealing element ( 300 ), wherein the means (measures) for achieving negative pressure are located inside the elastic sealing element ( 300 ). In this embodiment the elastic sealing part ( 300 ) is arranged on the second member ( 200 ) via its second surface ( 320 ), which in this embodiment consists of the circuit carrier ( 202 ), in particular having a planar and smooth surface The circuit board (204) constitutes. In this case, a recess ( 330 ) is located within the second surface ( 320 ) of the elastic sealing element ( 300 ), which recess acts as a pressure chamber. There is an underpressure in the recess ( 330 ) relative to the ambient pressure, in particular the atmospheric pressure, which causes the elastic sealing element ( 300 ) to adhere under pressure to the second component ( 320 ) (similar to a suction cup effect). The recess ( 330 ) forming the pressure chamber is inserted in...

Abstract

The invention relates to a device (600), in particular for an electronic control unit, having at least a first component (100) and having at least a second component (200) and having at least one elastic sealing part (300) arranged between the at least one first component (100) and the at least one second component (200), wherein the first component (100) bears against a first surface (310) of the at least one elastic sealing part (300), and a second surface (320) of the at least one elastic sealing part (300) bears against the second component (200). In order to secure the elastic sealing part (300) on the second component (200) in a positionally accurate and captive manner, provision is made here for the at least one elastic sealing part (300) to be provided with means for achieving vacuum adhesion of the at least one elastic sealing part (300) on the second component (200). The invention further relates to a method for producing a device which seals against external media, in which method the elastic sealing means (300) adheres by vacuum adhesion on the second component (200) in a positionally accurate and captive manner.

Description

technical field [0001] The invention relates to a device, in particular for an electronic controller, having the features stated in the preamble of the independent device claim, and to a method for manufacturing such a device. Background technique [0002] A device constructed in this way is known from DE 10 2007 029 913 A1. [0003] When using electronic devices, such as controllers used in motor vehicles, it is often necessary to protect electronic components from external media. For this purpose, the electronic components are arranged in a housing that is sealed against the external medium and has, for example, two components. In DE 10 2007 029 913 A1, the housing cover as the first component is fastened to the second component formed here by the circuit board in order to establish the tightness, and a sealing element in the form of an elastic seal is arranged between the housing cover and the circuit board, It is tightly pressed against the circuit board by the housing...
