Abstract

A dual connector system includes a host circuit board and first and second electrical connectors for electrically connecting to a module circuit board of a dual connector module. The dual connector module has a latch at a front wall movable between a latched position and an unlatched position. The latch engages a latching feature of the first electrical connector in the latched position. The dual connector module has an ejector at the front wall operably coupled to the latch. The ejector is actuated in an actuation direction to release the latch and eject the dual connector module from the mated position to the unmated position after the latch is moved from the latched position to the unlatched position.

First claim

What is claimed is:

1. A dual connector system comprising:
a host circuit board having a front mounting area and a rear mounting area;
a first electrical connector at the front mounting area of the host circuit board, the first electrical connector having a housing having a card slot, the housing holding first contacts at the card slot, the first contacts being terminated to the host circuit board, the first electrical connector having a latching feature;
a second electrical connector at the rear mounting area of the host circuit board, the second electrical connector having a housing having an upper mating surface, the housing holding second contacts at the upper mating surface, the second contacts being terminated to the host circuit board;
a dual connector module movable between a mated position and an unmated position with the first and second electrical connectors, the dual connector module having a module circuit board including an upper surface and a lower surface facing the host circuit board, the module circuit board having at least one communication component on the upper surface, the module circuit board extending between a front edge and a rear edge, the module circuit board having front contact pads proximate to the front edge for electrically connecting to the first electrical connector, the module circuit board having rear contact pads remote from the front edge for electrically connecting to the second electrical connector, the dual connector module having a front wall proximate to the front edge, the dual connector module having a latch at the front wall movable between a latched position and an unlatched position, the latch engaging the latching feature of the first electrical connector in the latched position to hold the dual connector module in the mated position with the first electrical connector, the dual connector module having an ejector at the front wall operably coupled to the latch, the ejector being actuated in an actuation direction to release the latch and eject the dual connector module from the mated position to the unmated position after the latch is moved from the latched position to the unlatched position.

2. The dual connector system of claim 1 , wherein the ejector forces the dual connector module in an unmating direction as the ejector is actuated after the latch is moved to the unlatched position.

3. The dual connector system of claim 1 , wherein the latch includes a support beam imparting a return force to return the latch to the latched position.

4. The dual connector system of claim 3 , wherein the return force forces the ejector to return to a released position.

5. The dual connector system of claim 1 , wherein the latch is lifted upward in an unlatching direction perpendicular to the acting direction of the ejector.

6. The dual connector system of claim 1 , wherein the latch includes a latching beam engaging the latching feature and a support beam fixed to the front wall, the support beam being elastically deformed as the latch is moved from the latched position to the unlatched position, the support beam returning to an undeformed state when the ejector is released to return the latch to the latched position.

7. The dual connector system of claim 1 , wherein the ejector extends forward of the front wall and is pushed rearward toward the front wall to actuate the latch, the ejector pushing the dual connector module rearward to the unmated position after the latch is released to the unlatched position.

8. The dual connector system of claim 1 , wherein the latch includes a cam surface, the ejector engaging the cam surface, the cam surface causing the ejector to return to a released position as the latch is moved downward from the unlatched position to the latched position.

9. The dual connector system of claim 1 , wherein the ejector is movable linearly parallel to the host circuit board between a released position and an actuated position, the latch being rotated upward from the latched position to the unlatched position as the ejector is moved rearward to the actuated position and rotated downward from the unlatched position to the latched position to cause the ejector to move forward to the released position.

10. The dual connector system of claim 1 , wherein the ejector is accessible forward of the dual connector module immediately above the first electrical connector.

11. A dual connector system comprising:
a host circuit board having a front mounting area and a rear mounting area;
a first electrical connector at the front mounting area of the host circuit board, the first electrical connector having a housing having a card slot, the housing holding first contacts at the card slot, the first contacts being terminated to the host circuit board, the first electrical connector having a latching feature;
a second electrical connector at the rear mounting area of the host circuit board, the second electrical connector having a housing having an upper mating surface, the housing holding second contacts at the upper mating surface, the second contacts being terminated to the host circuit board;
a dual connector module matable with the first and second electrical connectors, the dual connector module having a module circuit board including an upper surface and a lower surface facing the host circuit board, the module circuit board having at least one communication component on the upper surface, the module circuit board extending between a front edge and a rear edge, the module circuit board having front contact pads proximate to the front edge for electrically connecting to the first electrical connector, the module circuit board having rear contact pads remote from the front edge for electrically connecting to the second electrical connector, the dual connector module having a front wall proximate to the front edge, the dual connector module having a latch at the front wall movable between a latched position and an unlatched position, the latch engaging the latching feature of the first electrical connector in the latched position, wherein the dual connector module is coupled to the host circuit board by lowering the dual connector module in a loading direction generally perpendicular to the host circuit board to a pre-staged, unmated position where the first connector interface is adjacent to the first electrical connector and the second connector interface is adjacent to the second electrical connector, and wherein the dual connector module is slid forward from the pre-staged, unmated position to a mated position in a mating direction generally parallel to the upper surface of the host circuit board to mate the first connector interface to the first electrical connector by loading the front edge of the module circuit board into the card slot of the first electrical connector to mate the first contacts to the first contact pads and to mate the second connector interface to the second electrical connector to mate the second contacts to the second contact pads; and
an ejector provided at the front wall being operably coupled to the latch, the ejector is actuated in an actuation direction parallel to the host circuit board to release the latch and eject the dual connector module in an unmating direction from the mated position to the unmated position after the latch is moved from the latched position to the unlatched position.

12. The dual connector system of claim 11 , wherein the ejector forces the dual connector module in an unmating direction as the ejector is actuated after the latch is moved to the unlatched position.

13. The dual connector system of claim 11 , wherein the latch imparts a return force to force the ejector t
