Abstract
For electrically and mechanically connecting a printed circuit board bonding pad to a metallic housing part, in particular for connecting to ground, friction-type connections such as screw fastenings or rivets are usually provided for connecting the printed circuit board directly to the housing part. However, since the printed circuit boards are mostly made of plastic material and the forces at the friction-type connections diminish, the electrical connection may become loose, especially in the aging process. To prevent this a connecting element comprising a base surface having a hole for inserting the friction-type connection to the housing part and at least one contact finger on the base surface are provided, whereby the contact finger provides connection to the printed circuit board bonding pad. The base surface is insensitive to mechanical loads at the friction-type connection and can distribute these evenly. Electrical connection is guaranteed and fabrication simplified.
