Abstract

A communication system includes a first circuit card assembly having a first PCB and a first electrical connector having a receptacle housing and a mating housing received in the receptacle housing and being movable in the receptacle housing in a connector mating direction along a connector mating axis. The second circuit card assembly includes a second PCB and a second electrical connector having a header housing holding second contacts. The first PCB and/or the second PCB includes a slot receiving the other PCB in a board loading direction. The receptacle housing is coupled to the header housing in the board loading direction and the mating housing is movable within the receptacle housing toward the header housing in a connector mating direction generally perpendicular to the board loading direction.

First claim

What is claimed is:

1. A communication system comprising:
a first circuit card assembly having a first printed circuit board (PCB) and a first electrical connector mounted to the first PCB, the first electrical connector having a first mating end and first contacts at the first mating end, each of the first contacts having a first mating interface, the first electrical connector having a receptacle housing and a mating housing received in the receptacle housing and being movable in the receptacle housing in a connector mating direction along a connector mating axis; and
a second circuit card assembly having a second PCB and a second electrical connector mounted to the second PCB, the second electrical connector having a second mating end and second contacts at the second mating end, each of the second contacts having a second mating interface, the second electrical connector having a header housing holding the second contacts, the second mating end being oriented parallel to the second PCB, the second mating interfaces of the second contacts being arranged along the second mating end;
wherein at least one of the first PCB and the second PCB includes a slot receiving the other of the first PCB and the second PCB in a board loading direction along a board loading axis;
wherein the receptacle housing is coupled to the header housing in the board loading direction as the first PCB and the second PCB are mated, and wherein the mating housing is movable within the receptacle housing toward the header housing in the connector mating direction generally perpendicular to the board loading direction;
wherein the first electrical connector includes a driving element operably coupled to the mating housing, the driving element engaging the second electrical connector to force the mating housing to move in the connector mating direction.

2. The communication system of claim 1 , wherein the mating housing moves in the board loading direction with the receptacle housing and is configured to move independent of the receptacle housing in the connector mating direction.

3. The communication system of claim 1 , wherein the driving element of the first electrical connector includes a cam lever operably coupled between the receptacle housing and the mating housing, the cam lever engaging the second electrical connector to move the cam lever and force the mating housing to move relative to the receptacle housing.

4. The communication system of claim 1 , wherein the first electrical connector includes a cam lever pivotably coupled to the receptacle housing and pivotably coupled to the mating housing, the cam lever having a cam surface configured to engaging the second electrical connector to move the cam lever and force the mating housing to move relative to the receptacle housing toward the header housing, the cam lever having a return cam surface configured to engaging the second electrical connector to move the cam lever and force the mating housing to move relative to the receptacle housing away the header housing.

5. The communication system of claim 1 , wherein the first electrical connector includes a cam lever having a body including a first side and a second side, the cam lever includes a fixed pivot extending from the first side being pivotably coupled to the receptacle housing, the cam lever includes a movable pivot coupled to the mating housing, the cam lever includes a cam surface engaging the second electrical connector to cause rotation of the body about the fixed pivot, the rotation of the body causes the movable pivot to move relative to the receptacle housing causing the mating housing to move relative to the receptacle housing.

6. The communication system of claim 1 , wherein the header housing includes a wall defining a cavity configured to receive the mating housing, the wall having an actuator engaging the first electrical connector to actuate and move the mating housing relative to the receptacle housing.

7. The communication system of claim 1 , wherein the header housing includes a wall defining a cavity configured to receive the mating housing, the wall having an actuator including a ramp surface, the first electrical connector includes a cam lever pivotably coupled to the receptacle housing and pivotably coupled to the mating housing, the cam lever engaging the ramp surface to move the cam lever and force the mating housing to move relative to the receptacle housing.

8. The communication system of claim 1 , wherein the first electrical connector includes a front section and a rear section, the first electrical connector having a first driving element operably coupled to the mating housing at the front section for driving the mating housing in the connector mating direction relative to the receptacle housing at the front section and a second driving element operably coupled to the mating housing at the rear section for driving the mating housing in the connector mating direction relative to the receptacle housing at the rear section.

9. The communication system of claim 1 , wherein the first electrical connector includes a top and a bottom, the first electrical connector having a first driving element operably coupled to the mating housing at the top for driving the mating housing in the connector mating direction relative to the receptacle housing at the top and a second driving element operably coupled to the mating housing at the bottom for driving the mating housing in the connector mating direction relative to the receptacle housing at the bottom.

10. The communication system of claim 1 , wherein the header housing includes a gear member having gear teeth, the first electrical connector includes a crank having crank gear teeth engaging the gear teeth of the gear member causing the crank to rotate, the crank being operably coupled to the mating housing and causing the mating housing to move in the connector mating direction as the crank rotates.

11. The communication system of claim 1 , wherein the header housing includes an actuator, the first electrical connector includes a lever and at least one link member coupled to the lever and operably coupled to the mating housing, the lever engaging the actuator causing the at least one link member to move causing the mating housing to move in the connector mating direction.

12. The communication system of claim 1 , wherein the first and second PCBs move relative to each other along the board loading axis, the receptacle housing moves relative to the header housing along the board loading axis, and the mating housing moves relative to the header housing along the connector mating axis perpendicular to the board mating axis.

13. The communication system of claim 1 , wherein either the first PCB or the second PCB is oriented horizontally and the other of the first PCB or the second PCB is oriented vertically.

14. The communication system of claim 1 , wherein the first mating end is oriented perpendicular to the first PCB, and wherein the second mating end is oriented parallel to the second PCB.

15. A communication system comprising:
a first circuit card assembly having a first printed circuit board (PCB) and a first electrical connector mounted to the first PCB, the first electrical connector having a first mating end and first contacts at the first mating end, each of the first contacts having a first mating interface, the first electrical connector having a receptacle housing and a mating housing received in the receptacle housing and being movable in the receptacle housing in a connector mating direction along a connector mating axis; and
a second circuit card assembly having a second
