  • Patent number: 9209554
    Abstract: A housing for an electronic circuit includes a plug-housing part having an electric plug connector and a venting channel. A web is shaped onto an inside of the plug-housing part so as to delimit an installation area. A pressure equalizing element is disposed in the installation area below the venting channel and glued to the inside of the plug-housing part. The plug-housing part includes, in the installation area, a venting cutout having a first cross section disposed between the pressure equalizing element and a first venting channel. The first venting channel has a second cross section that is smaller than the first cross section and opens up into a second venting channel that runs essentially perpendicular to the first venting channel. The second venting channel is disposed inside a housing projection on an outside of the plug-housing part and has, at each axial end, an opening to the outside.
