Abstract: A repeater case capable of housing HDSL telecommunications modules without an excessive buildup of heat. The repeater case has a base, an open-topped housing, and a closure member that closes the housing. The closure member is provided in the form of a pair of thermal covers that share a common construction, including heat-radiating fins formed on their respective top walls and heat transferring structures positioned on the respective interior sides of their top walls. The housing includes multiple printed circuit boards to further enhance internal air flow, each of which is protected from short circuits by an acrylic plastic barrier mounted in vertically spaced apart relation from it. The spacing between each printed circuit board and its barrier provides ample space for the connection of individual conductors from a stub cable that enters the repeater case through an opening formed in the base. The spacing also enhances the air flow within the repeater case.
