Abstract

An electrical connector includes an insulative connector housing. The connector housing includes a longitudinal bottom wall having a plurality of contact openings, first and second side walls extending upwardly from the bottom wall at opposing sides of the bottom wall, first and second end walls extending upwardly from the bottom wall at opposing ends of the bottom wall, and first and second pairs of latch openings at opposing ends of the bottom wall. Each latch opening extends through the bottom wall and through a side wall and is configured to allow a latch to eject a mating connector by moving within the opening.

First claim

What is claimed is:

1. An electrical connector comprising:
an insulative connector housing including a longitudinal bottom wall having a plurality of contact openings, first and second side walls extending upwardly from the bottom wall at opposing sides of the bottom wall, first and second end walls extending upwardly from the bottom wall at opposing ends of the bottom wall, and first and second pairs of latch openings at opposing ends of the bottom wall, each latch opening extending through the bottom wall and through a side wall, such that when a latch is pivotably attached to the connector housing at an end of the bottom wall, the latch is configured to eject a mating connector by moving within the pair of latch openings at the end of the bottom wall.

2. The electrical connector of claim 1 , wherein the bottom wall further includes first and second end standoffs extending downwardly therefrom at opposing ends of the connector housing.

3. The electrical connector of claim 1 , wherein the bottom wall further includes at least one center standoff extending downwardly therefrom between opposing ends of the connector housing.

4. The electrical connector of claim 1 , wherein the bottom wall further includes engagement edges at opposing ends thereof and shaped to engage with portions of the latches.

5. The electrical connector of claim 1 , wherein a portion of the bottom wall is positioned between at least one of the first and second pairs of latch openings.

6. The electrical connector of claim 1 , wherein the side walls include an electrical conductor recess between opposing ends of the connector housing and configured to receive a portion of an electrical conductor.

7. The electrical connector of claim 1 , wherein one of the side walls includes a polarization opening at a middle thereof and configured to receive a portion of a polarization element of a mating connector.

8. The electrical connector of claim 7 , wherein the side wall includes a pair of engagement elements extending into the polarization opening, the engagement elements including an interior surface configured to frictionally engage with a polarization element of a mating connector.

9. The electrical connector of claim 1 , wherein one of the side walls includes engagement ramps extending from an interior surface thereof and configured to engage with a mating connector.

10. The electrical connector of claim 1 , wherein the side walls and the end walls include chamfers configured to accommodate engagement of the mating connector.

11. The electrical connector of claim 1 , wherein the end walls include a slot positioned between opposing sides of the connector housing and configured to frictionally engage with a friction lock of the latches.

12. The electrical connector of claim 11 , wherein the slot has a curvilinear shape.

13. The electrical connector of claim 1 , wherein the end walls include a retention clip retainer having a retention clip opening extending therethrough in an insertion direction and configured to receive a portion of a retention clip.

14. The electrical connector of claim 1 , wherein the insulative connector housing further includes first and second pivot pin holes extending through the bottom wall in a transverse direction perpendicular to an insertion direction at opposing ends of the connector housing, each pivot pin hole configured to receive a portion of a pivot pin.

15. The electrical connector of claim 14 , wherein each pivot pin hole includes a restricted portion configured to position and retain a pivot pin.

16. The electrical connector of claim 1 , wherein the latch openings are shaped to accommodate a pivoting motion of the latches.

17. The electrical connector of claim 1 , wherein the latch openings extend into the bottom wall beyond the side walls.

18. The electrical connector of claim 1 , wherein the bottom wall includes a friction bump recess in a side surface thereof behind each latch opening, configured to receive a friction bump of the latches.

19. The electrical connector of claim 1 further comprising first and second latches pivotably attached to the connector housing at opposing ends thereof.

20. The electrical connector of claim 19 further comprising first and second pivot pins configured to pivotably attach the respective first and second latches to the connector housing.

21. The electrical connector of claim 20 , wherein the pivot pins include a recessed portion configured to position and retain the pivot pins in the connector housing.

22. The electrical connector of claim 19 , wherein the connector housing has a length that is less than about 36 mm and includes at least 50 contact openings, and wherein the latches add less than about 30% to the length of the electrical connector.

23. The electrical connector of claim 1 further comprising a plurality of electrical contact pins extending through the contact openings in an insertion direction.

24. The electrical connector of claim 1 further comprising first and second retention clips attached to the connector housing at opposing ends thereof.
