ABSTRACT:
A holder molded of suitable elastomeric material cradles a plug-in relay in operating position, with access openings for calibration adjustments, visual inspection of contacts, and plug coupling of connecting leads. The holder is mounted to a mounting plate and/or the shelf by bolts inserted into cylindrical openings in the bottom of the holder and through a web or diaphragm molded as an integral part of the holder. A spacer tube placed over each bolt spaces the holder a selected distance above the mounting plate. Washer disks of the elastomeric material are placed on both sides of the diaphragm and a lock nut secured onto the bolt to fasten the holder in place. The diaphragms, disks, and spacers combine to provide vibration damping and shock isolation for the relay.
