Abstract: Example implementations relate to an insertion key assembly for a pluggable module. The insertion key assembly includes a stopper element having a stopping tab, a biasing element, and a driver element having a driving tab. The biasing element is connected to the stopper element and the driver element. In a relaxed state of the biasing element: i) the stopper element is pushed outwards by the biasing element to protrude the stopping tab into a passageway defined by a plurality of walls of a chassis, to block insertion of the pluggable module inside the passageway, and ii) the driver element is pushed outwards by the biasing element to protrude the driving tab into adjacent passageway. In a biased state of the biasing element, the stopper element is pulled inwards by the biasing element to retract the stopping tab from the passageway to allow insertion of the pluggable module inside the passageway.

Abstract: A technique and corresponding device to provide for a floating heat sink is disclosed. The technique includes a method that allows for insertion of an electronic component (e.g., an optical transceiver) into a cage that has a pre-installed heatsink. At the beginning phases of insertion, no friction is present between the electronic component and the heatsink. At or very near an insertion end phase (the electronic component is almost fully inserted), an actuator (e.g., roller or button) is impacted to impart a pivot motion via a lever arm to cause lowering of the heatsink toward the electronic component. A thermal interface material (TIM) may therefore be present to establish a thermal coupling between the heatsink and the electronic component. The TIM and heatsink contact the electronic component via a downward motion (caused by the pivot) to provide a nearly frictionless sliding impact to the TIM.
