Abstract

A header transition connector includes a header housing having a separating wall separating a first cavity from a second cavity. Header signal contacts are held by the header housing. The header signal contacts are arranged in pairs carrying differential signals. The header signal contacts have first mating ends in the first cavity for mating with a first receptacle connector. The header signal contacts have second mating ends in the second cavity for mating with a second receptacle connector. Header ground shields are held by the header housing. The header ground shields have first mating ends in the first cavity for mating with the first receptacle connector. The header ground shields have second mating ends in the second cavity for mating with the second receptacle connector. At least a group of the header ground shields are electrically commoned with each other within the header housing.

First claim

What is claimed is:

1. A header transition connector comprising:
a header housing having a separating wall separating a first cavity from a second cavity;
header signal contacts held by the header housing, the header signal contacts arranged in pairs carrying differential signals, the header signal contacts having first mating ends in the first cavity for mating with a first receptacle connector, the header signal contacts having second mating ends in the second cavity for mating with a second receptacle connector; and
header ground shields held by the header housing, the header ground shields having walls surrounding associated pairs of header signal contacts on at least two sides thereof, the header ground shields having first mating ends in the first cavity for mating with the first receptacle connector, the header ground shields having second mating ends in the second cavity for mating with the second receptacle connector, the header ground shield comprising an engagement feature integral with the corresponding header ground shield, the engagement feature having an engagement surface, wherein at least a group of the header ground shields are electrically commoned via engagement of the engagement feature in physical contact at the engagement surface with at least one other header ground shield of the group within the header housing.

2. The header transition connector of claim 1 , wherein the header ground shields are arranged in an array of rows and columns, the group of header ground shields comprising header ground shields within a first column of the columns.

3. The header transition connector of claim 1 , wherein the header ground shields are arranged in an array of rows and columns, the group of header ground shields comprising header ground shields within a first row of the rows.

4. The header transition connector of claim 1 , wherein the header ground shields are arranged in an array of rows and columns, the group of header ground shields comprising header ground shields within a first column of the columns, at least some of the header ground shields of each other column being electrically commoned with at least some of the other header ground shields of the same column.

5. The header transition connector of claim 1 , wherein the header ground shields are arranged in an array of rows and columns, the group of header ground shields comprising header ground shields within a first column of the columns, at least some of the header ground shields of each other column being electrically commoned with at least some of the other header ground shields of the same column, at least some of the header ground shields of each row being electrically commoned with at least some of the other header ground shields of the same row.

6. The header transition connector of claim 1 , wherein the header ground shields are arranged in an array of rows and columns, the group of header ground shields comprising header ground shields within a first column of the columns, the header ground shields of the group being electrically commoned with each other via engagement in physical contact with another header ground shield of the group that is adjacent within the first column.

7. The header transition connector of claim 1 , wherein the engagement feature is a spring arm that is engaged in physical contact with another header ground shield of the group to electrically common the header ground shields of the group.

8. The header transition connector of claim 1 , wherein the engagement feature is a tab that is engaged in physical contact with another header ground shield of the group to electrically common the header ground shields of the group.

9. The header transition connector of claim 1 , wherein the walls of the header ground shields comprise base walls and side walls that extend from the base walls, the engagement feature extends from the base wall and is engaged in physical contact with an end of a side wall of another header ground shield of the group to electrically common the header ground shields of the group.

10. The header transition connector of claim 1 , wherein the header ground shields are C-shaped.

11. The header transition connector of claim 1 , wherein the walls of the header ground shield comprise a base wall and a side wall that extends from the base wall, the base wall spanning across both header signal contacts of the corresponding pair of header signal contacts.

12. The header transition connector of claim 1 , wherein the header ground shield is a stamped and formed structure, the engagement feature is formed from the header ground shield.

13. A header transition connector comprising:
a header housing having a separating wall separating a first cavity from a second cavity;
header signal contacts held by the header housing, the header signal contacts arranged in pairs carrying differential signals, the header signal contacts having first mating ends in the first cavity for mating with a first receptacle connector, the header signal contacts having second mating ends in the second cavity for mating with a second receptacle connector; and
header ground shields held by the header housing, the header ground shields having walls surrounding associated pairs of header signal contacts on at least two sides thereof, the header ground shields having first mating ends in the first cavity for mating with the first receptacle connector, the header ground shields having second mating ends in the second cavity for mating with the second receptacle connector, the header ground shield comprising an engagement feature integral with the corresponding header ground shield, the engagement feature having an engagement surface, wherein the engagement feature of a first header ground shield is engaged in physical contact at the engagement surface with a second header ground shields such that the first and second header ground shields are electrically connected together.

14. The header transition connector of claim 13 , wherein the header ground shields are arranged in an array of rows and columns, the first and second header ground shields being arranged within the same column.

15. The header transition connector of claim 13 , wherein the header ground shields are arranged in an array of rows and columns, the first and second header ground shields being arranged adjacent to each other within the same column.

16. The header transition connector of claim 13 , wherein the header ground shields are arranged in an array of rows and columns, the first and second header ground shields being arranged within a first column of the columns, at least some of the header ground shields of the first column being electrically commoned with each other within the header housing.

17. The header transition connector of claim 13 , wherein engagement feature is a spring arm that is engaged in physical contact with the second header ground shield to electrically connect the first and second header ground shields.

18. The header transition connector of claim 13 , wherein the engagement feature is a tab that is engaged in physical contact with the second header ground shield to electrically connect the first and second header ground shields.

19. The header transition connector of claim 13 , wherein the walls of the header ground shields comprise base walls and side walls that extend from the base walls, the engagement feature extends from the base wall and is engaged in physical contact with an end of a side wall of the second header ground shield to electrically connect the first and second header
