Abstract
A track mounting device for printed circuit board includes an elongated channel member of generally U-shaped cross-section, and including intermediate opposed resilient finger means for resiliently gripping the circuit board, as well as opposed intermediate thickened portions for reinforcing the upstanding parallel side walls of the track device. Furthermore, the track mounting device is provided with opposed protrusions disposed at the opposite ends of the side walls and projecting into the space between said side walls. The spacing between the opposed protrusions is less than the spacing between the opposed thickened portions, but greater than the spacing between the opposed resilient fingers. The end protrusions limit the vibration of the printed circuit board at its extremities where vibrations are the greatest, and also prevent the inadvertant insertion into the track of oversized (thickness) printed circuit cards. The protrusions also aid in reinforcing the upstanding side walls of the track mounting device.
