Abstract: An electrical connector assembly adapted to be removably secured to a supporting mounting plate and featuring mounting clip spring adjustments to accommodate variations in mounting plate thickness. Mounting clips at each end of the assembly are each provided with a horizontal flange having slightly downturned ends adapted to make spring action engagement with one surface of a mounting plate. Each clip also has a blade adapted for insertion into an access slot of the mounting plate, the blade having deflectable shoulders for engaging the opposite surface of the mounting plate. Mounting plate thickness variations may thus be accommodated by the spring action of both the flange ends and the shoulders as the mounting plate is gripped therebetween.
