An arrangement for introducing a plate element, for which heat needs to be dissipated by means of conduction, into a slot of a chassis which is adapted to absorb the heat. The slot has a back wall adapted to contact the plate element upon its insertion, an opposing front wall, and a base wall. The plate element has margins adapted for carrying the arrangement. The arrangement comprises has a seat located on the margins. The arrangement further has a wedgelock moveably attached to the seat, having two slot engaging surfaces adapted to contact the front and base walls of the slot, and a seat engaging portion adapted to contact the seat. The arrangement further has an actuating mechanism adapted to cause a movement of the wedgelock in a direction toward the front wall and in a direction toward the base wall of the slot until a tight contact is established between the slot engaging surfaces of the wedgelock and the slot's front and base walls, while maintaining a tight contact between the seat engaging portion of the wedgelock and the seat and between the module and the back wall of the slot.

Wedgelock for electronic circuit card module

A conduction cooled electronic card module is designed for insertion into a chassis of an electronic device so as to transfer thereto a heat generated by electronic components of the module. The module comprises a circuit card of a convection cooled type, and a thermally conductive frame carrying the circuit card. The circuit card has a front surface carrying at least a part of the electronic components, and a rear surface at least edge areas of which are adapted to be in thermal contact with the chassis. The frame is in thermal contact with the part of the electronic components and with the front surface of the circuit card at least at edge areas thereof, so as to conduct heat generated by the electronic components, via the edge areas of the front surface to the edge areas of the rear surface of the circuit card.
