Electronic device with female screw and structure for mounting the electronic device in the interior of an automobile










Image Number 3 for United States Patent #5674025.

An electronic device mounting structure, which allows threaded engagement with a standardized male screw compliant with the JIS, DIN or the like without having to perform tapping on a plate material, includes an engagement hole having first and second cutouts formed in a peripheral edge section thereof, wherein the peripheral edge section of the engagement hole is deformed in the plate thickness direction such that there is a positional deviation from a first peripheral edge end section bordering on the first cutout toward a second peripheral edge section bordering on the second cutout by approximately one half of the pitch of a standardized male screw compliant with the JIS and a further positional deviation from a third peripheral edge end section bordering on the second cutout toward a fourth peripheral edge end section bordering on the first cutout by approximately one half of the pitch, with the result that there is a positional deviation corresponding to one pitch of the male screw between the first and fourth peripheral edge end sections on opposite sides of the first cutout, thereby making it possible for the male screw compliant with the JIS to be threadedly engaged with the engagement hole. The provision of two cutouts in the engagement hole makes it possible for the peripheral edge section to be deformed with high accuracy.
