Abstract

A card edge connector assembly includes a card edge connector having a housing defining a card slot receiving a pluggable module and a card guide module coupled to the housing. The card guide module has a main body having a cavity receiving the pluggable module and support beams secured to the host circuit board with a window defined between the support beams under the main body receiving the card edge connector. A latch is coupled to the main body being latchably coupled to the pluggable module in a latched position to secure the pluggable module in the cavity and being decoupled from the pluggable module in an unlatched position to allow the pluggable module to be removed from the cavity. An actuator with a ramp surface may be pressed downwardly to drive the latch to the unlatched position.

5. The card edge connector assembly of claim 1, wherein the latching member includes a latching finger extending through a wall of the main body into the cavity to engage the pluggable module in the latched position.

6. The card edge connector assembly of claim 1, wherein the latch includes a latching finger movable in a latching direction perpendicular to a loading direction of the pluggable module into the cavity.

7. The card edge connector assembly of claim 1, wherein the support beams include locating surfaces engaging the housing of the card edge connector to locate the card guide module with respect to the card edge connector.

8. The card edge connector assembly of claim 1, wherein the card guide module includes a guide surface in the cavity to locate the pluggable module in the cavity.

9. The card edge connector assembly of claim 1, wherein the main body includes a first side and a second side, the main body includes a first end and a second end between the first and second sides with the first and second sides being wider than the first and second ends, the main body includes a top between the first and second sides and between the first and second ends having a top opening to the cavity for receiving the pluggable module, and the main body includes a bottom between the first and second sides and between the first and second ends having a bottom opening to the window for loading the pluggable module into the card edge connector, the latch being coupled to the first side of the main body.

10. The card edge connector assembly of claim 9, wherein the main body includes a latch frame extending from the first side defining a latch pocket, the latch being received in the latch pocket, the latch having a latching finger extending through a slot in the first side of the main body to engage the pluggable module in the cavity in the latched position.

11. The card edge connector assembly of claim 1, wherein the latch includes a return spring being spring biased against the main body to force the latch to return to the latched position.

12. The card edge connector assembly of claim 1, wherein the main body includes a track, the latch including a rail received in the track to guide actuation of the latch.

13. The card edge connector assembly of claim 1, wherein the latch includes a latching finger having a ramp surface configured to engage the pluggable module when the pluggable module is loaded into the cavity to force the latch to the unlatched position as the pluggable module is loaded into the cavity.

14. A card edge connector assembly comprising:

a card edge connector having a housing defining a card slot configured to receive a pluggable module in a mating direction, the housing holding contacts in the card slot to electrically connect to the pluggable module, the contacts being configured to be electrically connected to a host circuit board;

a card guide module having a main body having a cavity configured to receive the pluggable module, the card guide module having support beams extending from the main body configured to be secured to the host circuit board, wherein the support beams support the main body independent of the card edge connector on the host circuit board, the card guide module having a window defined between the support beams under the main body receiving the card edge connector; and

a latch coupled to the main body movable between a latched position and an unlatched position, the latch latchably coupled to the pluggable module in the latched position to secure the pluggable module in the cavity, the latch being decoupled from the pluggable module in the unlatched position to allow the pluggable module to be removed from the cavity.

15. The card edge connector assembly of claim 14, wherein the latch includes a latching member and an actuator operably coupled to the latching member.

16. A card edge connector assembly comprising:
