Abstract

A connector includes a first and second housing that are configured to be coupled together. The connector may include two circuit cards supported by card supports. Mating edges of the first and second housing are configured to be coupled together and may include one or more crushed ribs positioned in an elongated channel/elongated shoulder interface. The one or more crushed ribs may be configured so as to be spaced apart a distance that acts to improve the electrical shielding provided by the connector. The connector may be configured to be coupled to a cable.

Claims

1. A connector, comprising:

a first housing with a first mating edge extending a first length, the first mating edge including a first elongated slot extending along a portion of the first length, the first elongated slot including a plurality of ribs;

a second housing with an elongated shoulder configured to be inserted into the elongated slot, the elongated shoulder configured to fill a portion of the elongated slot so as to crush the plurality of ribs when the first and second housing are joined, wherein the first and second housing define an interior cavity; and

a circuit card positioned in the interior cavity, the circuit card including a plurality of contact pads on a first end, the contact pads configured in operation to engage terminals in a corresponding connector.

2. The connector of claim 1, wherein the first housing further includes a second mating edge with a second elongated slot, the second elongated slot including a plurality of spaced-apart ribs and the second housing including a second elongated shoulder configured to be inserted into the second elongated slot.

3. The connector of claim 2, wherein the plurality of ribs in the first and second elongated slots are positioned on alternating sides of the elongated slots.

4. The connector of claim 3, wherein the plurality of ribs are spaced apart not more than 3 millimeters

5. The connector of claim 1, wherein the plurality of ribs are spaced apart so as to be separated a distance of about two to six millimeters between adjacent ribs.

6. The connector of claim 5, wherein elongated slot has a width and the plurality of ribs extend a distance into the elongated slot that is about ten to 26 percent of the width.

7. The connector of claim 1, wherein the circuit card is a first circuit card, the connector further comprising at least one additional circuit card.

8. A connector, comprising:

a two-piece housing defining an internal cavity, the two-piece housing including a first mating intersection between the two pieces, the first mating intersection including a first side and a second side, wherein the first side includes a first mating edge with a first elongated slot and the second side includes a first elongated shoulder configured to be inserted into the first elongated slot;

at least one crushed rib positioned between the first elongated slot and the first elongated shoulder; and

a circuit card positioned at least partially in the internal cavity and supported by the housing, the circuit card including a plurality of contact pads on a first end.

9. The connector of claim 8, wherein the two-piece housing further include a second mating intersection with a third side and a fourth side, wherein the third side includes a second mating edge with a second elongated slot and the fourth side includes a second elongated shoulder configured to be inserted in the second elongated slot, the connector further including at least one crushed rib between the second elongated slot and the second elongated shoulder.

10. The connector of claim 9, wherein the at least one crushed rib in the first elongated slot and the at least one rib in the second elongated slot are each a plurality of ribs spaced apart so as to be not more than about six millimeters apart.

11. The connector of claim 10, wherein the plurality of ribs are positioned on alternate sides of the respective first and second elongated slot and are positioned not more than three millimeters apart.

12. The connector of claim 9, wherein the circuit card is a first circuit card, the connector further comprising at least a second circuit card, the first and at least second circuit card being arranged in a substantially parallel alignment.

13. The connector of claim 9, further comprising a plurality of fasteners configured to couple the two-piece housing together.

14. The connector of claim 13, wherein the two-piece housing includes a first side with a latch groove and further includes a second side and opposing third side, wherein the plurality of fasteners are positioned on the second and opposing third side.

15. A connector, comprising:

a first and second housing coupled together and defining an internal cavity and a plug portion, wherein one of the first and second housing includes a first mating edge with a first elongated slot, and the other of the first and second housing include a first elongated shoulder inserted in the first elongated slot;

a plurality of crushed ribs positioned between the first elongated shoulder and the first elongated slot; and

at least one circuit card positioned in the internal cavity of housing and extending into the plug portion.

16. The connector of claim 15, wherein one of the first and second housing includes a second mating edge with a second elongated slot and the other of the first and second housing includes a second elongated shoulder inserted into the second elongated slot, the connector further comprising a plurality of crushed ribs that are spaced apart and are positioned between the second elongated shoulder and the second elongated slot.

17. The connector of claim 15, wherein the plurality of ribs are positioned not more than six millimeters apart.

18. The connector of claim 15, wherein the first mating edge does not extend into the plug portion and the at least one circuit card extends partially out of the plug portion and the plurality of crushed ribs are positioned on alternating sides of the first elongated slot.

19. The connector of claim 18, wherein the elongated slot has a width and, prior to insertion of the elongated shoulder into the elongated slot, the plurality of ribs extends into the elongated slot a distance that is between about ten to twenty six percent of a width of the elongated slot.

20. The connector of claim 15, wherein the first and second housing are coupled together with a plurality of clips that crimp the first and second housing together.

21. The connector of claim 15, wherein one of the first and second housing includes a first face, a second face and a third face, the first face including a latch groove positioned thereon, wherein the first and second housing are coupled together with a plurality of fasteners and at least one of the plurality of fasteners is mounted on each of the second and third face.

22. The connector of 15, wherein the connector is configured to engage a plurality of cables.
