Abstract
Latching mechanisms for pluggable electronic devices when received within a host cage of a host device. In one example embodiment, the host cage is configured to be connected to a host printed circuit board and configured to at least partially surround a host connector. The host cage includes a pair of inwardly biased leaf springs that extend toward the host connector and thereby engage with the latching mechanism of the pluggable electronic module in order to secure the pluggable electronic module within the host cage.
Claims15
A host device comprising:
- a host connector connected to a host printed circuit board, the host connector sized and shaped to receive and electrically connect to an edge connector of a printed circuit board of a pluggable electronic device;
- and
- a host cage connected to the host printed circuit board and shaped to at least partially surround the host connector, the host cage also sized and shaped to at least partially receive the pluggable electronic device, the host cage including a pair of inwardly biased leaf springs that extend toward the host connector;
- wherein the host connector comprises a hard stop for the pluggable electronic device such that the pluggable electronic device abuts the host connector to prevent the pluggable electronic device from being inserted further into the host cage;
- wherein the hard stop includes an upper face and a lower face of the host connector, the upper face and the lower face defining a slot sized and shaped to receive the edge connector of the printed circuit board, the slot positioned between the upper face and the lower face, the upper face and the lower face positioned to abut the pluggable electronic device when the edge connector of the printed circuit board is positioned in the slot;
- and
- conductive pads, the conductive pads positioned entirely in the slot between the upper face and the lower face.
