Abstract

A dual connector system includes a host circuit board with first and second electrical connectors. The first electrical connector has a housing with a card slot, first contacts and a latching feature. The second electrical connector has a housing with second contacts. The dual connector system includes a dual connector module having a module circuit board having contact pads. The dual connector module has a latch movable between a latched position and an unlatched position. The latch engages the latching feature of the first electrical connector in the latched position to hold the dual connector module in a mated position. A release mechanism is operably coupled between the dual connector module and at least one of the first electrical connector and the second electrical connector. The release mechanism forces the dual connector module to an 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 having first and second side edges 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 latch 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; and
a release mechanism operably coupled between the dual connector module and at least one of the first electrical connector and the second electrical connector, the release mechanism forcing the dual connector module 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 release mechanism ejects the dual connector module from the first electrical connector.

3. The dual connector system of claim 1 , wherein the release mechanism includes a spring imparting a spring force on the dual connector module in an un-mating direction parallel to the host circuit board.

4. The dual connector system of claim 1 , wherein the release mechanism is compressed as the dual connector module is moved from the unmated position to the mated position and the release mechanism is extended as the dual connector module is moved from the mated position to the unmated position.

5. The dual connector system of claim 1 , wherein the dual connector module includes a tab extending below the lower surface of the module circuit board, the tab engaging the second electrical connector, the release mechanism being positioned between the tab and the second electrical connector.

6. The dual connector system of claim 5 , wherein the tab engages a ledge of the second electrical connector to prevent lift off of the module circuit board from the upper mounting surface of the second electrical connector.

7. The dual connector system of claim 1 , wherein the release mechanism is coupled to the second electrical connector remote from the latch and is compressed by the dual connector module when the dual connector module is moved from the unmated position to the mated position.

8. The dual connector system of claim 1 , wherein the release mechanism is coupled to the first electrical connector and is compressed by the dual connector module when the dual connector module is moved from the unmated position to the mated position.

9. The dual connector system of claim 1 , wherein the release mechanism is coupled to the dual connector module and is compressed by the dual connector module against at least one of the first electrical connector and the second electrical connector when the dual connector module is moved from the unmated position to the mated position.

10. The dual connector system of claim 1 , wherein the latch is released in a releasing direction perpendicular to the acting direction of the release mechanism.

11. The dual connector system of claim 1 , wherein the latch includes a latching beam engaging the latching feature and an actuator coupled to the latching beam and operated to actuate the latching beam from the latched position to the unlatched position.

12. The dual connector system of claim 11 , wherein the latching beam and the actuator are contained forward of the second electrical connector.

13. 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 having first and second side edges 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 latch 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
a release mechanism operably coupled between the dual connector module and at least one of the first electrical connector and the second electrical connector, the release mechanism forcing the dual connector module to the pre-staged unmated position after the latch is moved from the latched position to the unlatched position.
