Abstract

An example apparatus for connecting linear edge cards includes a housing to hold at least one set of conductive contacts facing perpendicularly towards a mating plane. The apparatus further includes an activator bar coupled to the housing, the activator bar to hold two parts of the housing apart via two opposing normal forces. The apparatus also includes a contact load spring coupled to the housing, the contact load spring to apply two forces parallel to the direction of the conductive contacts and against the two opposing normal forces of the activator bar. The apparatus further includes an ejector spring coupled to the contact load spring and the activator bar. The ejector spring is to apply a force perpendicular to the two opposing normal forces of the activator bar and in a direction of an opening of the housing.

First claim

What is claimed is:

1. An apparatus for connecting linear edge cards, comprising:
a housing to hold at least one set of conductive contacts facing perpendicularly towards a mating plane;
an activator bar coupled to the housing, the activator bar to hold two parts of the housing apart via two opposing normal forces;
a contact load spring coupled to the housing, the contact load spring to apply two forces parallel to the direction of the conductive contacts and against the two opposing normal forces of the activator bar; and
an ejector spring coupled to the contact load spring and the activator bar, the ejector spring to apply a force perpendicular to the two opposing normal forces of the activator bar and in a direction of an opening of the housing.

2. The apparatus of claim 1 , wherein the activator bar further comprises a recess parallel to the mating plane to receive a circuit board and guide the circuit board into a position for insertion.

3. The apparatus of claim 1 , wherein the housing further comprises two ramps, the two ramps to guide the activator bar between a closed position and an open position.

4. The apparatus of claim 1 , further comprising a plurality of cables electrically coupled to the conductive contacts of the housing.

5. The apparatus of claim 1 , further comprising at least one ground bar coupled to the housing to provide grounding for the conductive contacts.

6. The apparatus of claim 1 , wherein the housing comprises two sets of conductive contacts facing perpendicular to the mating plane and in opposing directions towards the mating plane.

7. The apparatus of claim 1 , further comprising an over-molding coupled to the housing to protect the apparatus from contamination.

8. A method for connecting circuit boards, comprising:
receiving a circuit board at an activator bar;
engaging, via a force from the circuit board, an ejector spring until the activator bar reaches a closed position, the ejector spring applying a force perpendicular to the two opposing normal forces of the activator bar and in a direction of an opening of a housing; and
engaging, via a contact load spring force, contacts of the housing to circuit board pads of the circuit board, wherein the contacts of the housing engage the circuit board pads at a perpendicular angle to the force from the circuit board.

9. The method of claim 8 , further comprising engaging, via the contact load spring force, the housing with a notch or a hole in the circuit board to stabilize the circuit board.

10. The method of claim 8 , further comprising providing a tactile indication of a proper mating via a snapping of the activator bar into the housing in response to the activator bar reaching the closed position.

11. The method of claim 8 , further comprising guiding the circuit board into a position for insertion.

12. The method of claim 8 , wherein the circuit board is inserted into the housing without any contact between the contacts of the housing and the circuit board pads until the activator bar reaches the closed position.

13. The method of claim 8 , further comprising ejecting the circuit board via the ejector spring in response to a release of the contact load spring.

14. A system for connecting linear edge cards, comprising:
a linear edge card connector comprising:
a housing to hold at least one set of conductive contacts facing perpendicularly towards a mating plane;
an activator bar coupled to the housing, the activator bar to hold two parts of the housing apart via two opposing normal forces;
a contact load spring coupled to the housing, the contact load spring to apply two forces parallel to the direction of the conductive contacts and against the two opposing normal forces of the activator bar;
an ejector spring coupled to the contact load spring and the activator bar, the ejector spring to apply a force perpendicular to the two opposing normal forces of the activator bar and in a direction of an opening of the housing; and

a circuit board to be coupled to the linear edge card connector via the at least one set of conductive contacts and the activator bar.

15. The system of claim 14 , wherein the circuit board is to be further coupled to the housing via coupling between the housing and a notch or a hole in the circuit board.

16. The system of claim 14 , wherein the activator bar further comprises a recess parallel to the mating plane to receive the circuit board and guide the circuit board into a position for insertion.

17. The system of claim 14 , wherein the housing further comprises two ramps, the two ramps to guide the activator bar between a closed position and an open position.

18. The system of claim 14 , wherein the housing comprises a lead-in to guide the circuit board into position for insertion.

19. The system of claim 14 , wherein the circuit board is to communicate with the system via high speed signaling.
