Abstract

A direct mate orthogonal connector for a high density of high speed signals. The connector may include right angle leadframe assemblies with signal conductive elements and ground shields held by a leadframe housing. The leadframe assemblies may each have signal mating ends extending from the signal conductive elements and ground mating ends extending from the ground shield. High frequency performance may be achieved with features on the leadframe housing and on the ground shield. The features may be simple to form yet ensure the positional relationship between the contacts points of the ground mating ends and the contact points of the signal mating ends to sustain forces generated during operating the connector to mate with another connector and/or mount to a board.

First claim

What is claimed is:

1 . A lead assembly comprising:
a plurality of conductive elements, each of the plurality of conductive element comprising a mating end, a mounting end opposite the mating end, and an intermediate portion extending between the mating end and the mounting end, the mating ends of the plurality of conductive elements aligned in a first row, the mounting ends of the plurality of conductive elements aligned in a second row parallel to the first row, wherein the intermediate portions of the plurality of conductive elements are bent so as to provide first segments parallel to the mating ends and second segments parallel to the mounting ends; an assembly housing holding the intermediate portions of the plurality of conductive elements, the assembly housing comprising a first portion holding the first segments of the plurality of conductive elements and comprising a first plurality of projections, and a second portion holding the second segments of the plurality of conductive elements and comprising a second plurality of projections; and a shield separated from the plurality of conductive elements by the assembly housing, the shield comprising:
a first plurality of openings having the first plurality of projections extending therethrough;
a second plurality of openings having the second plurality of projections extending therethrough;
a plurality of mating ends aligned in the first row; and
a plurality of mounting ends aligned in a third row that is parallel to and offset from the second row,

wherein:
the second plurality of openings are partially unfilled.

2 . The lead assembly of claim 1 , wherein:
the first plurality of projections have distal portions that are wider, in at least one direction, than the first plurality of openings; and the second plurality of projections have distal portions that are wider, in at least one direction, than the second plurality of openings.

3 . The lead assembly of claim 1 , wherein:
the first plurality of openings are circular, and the second plurality of openings are elongated.

4 . The lead assembly of claim 1 , wherein:
the first plurality of projections have a same size of the second plurality of projections, and the first plurality of openings are smaller than the second plurality of openings.

5 . The lead assembly of claim 1 , wherein:
the first plurality of projections are disposed in rows parallel to the first row and columns perpendicular to the first row.

6 . The lead assembly of claim 5 , wherein:
the first portion of the assembly housing comprises a plurality of first openings that separate the first plurality of projections in the rows.

7 . The lead assembly of claim 6 , wherein:
the first portion of the assembly housing comprises a plurality of second openings disposed in rows parallel to the first row and offset from the rows of the first plurality of projections.

8 . The lead assembly of claim 7 , wherein:
portions of the intermediate portions of the plurality of conductive elements are exposed through the plurality of first openings and the plurality of second openings, and the exposed portions of the intermediate portions of the plurality of conductive elements are wider than unexposed portions of the intermediate portions of the plurality of conductive elements.

9 . An electrical connector comprising:
a housing; and a plurality of lead assemblies held by the housing, each lead assembly comprising:
a plurality of conductive elements, each of the plurality of conductive elements comprising a mating end, a mounting end opposite the mating ends, and an intermediate portion extending between the mating end and the mounting end,
an assembly housing holding the intermediate portions of the plurality of conductive elements and comprising a first plurality of projections and a second plurality of projections, and
a shield coupled to the assembly housing and comprising a body comprising:
a first plurality of openings having the first plurality of projections extending therethrough; and
a second plurality of openings having the second plurality of projections extending therethrough,

wherein:
the first plurality of projections have a same size of the second plurality of projections,
the first plurality of openings are smaller than the second plurality of openings, and
the first plurality of openings of the body of the shield is closer to the mating ends than the second plurality of openings of the body of the shield.

10 . The electrical connector of claim 9 , wherein:
the shield comprises a plurality of mating ends aligned in a first row, the mounting ends of the plurality of conductive elements are aligned in a second row, and the shield comprises a plurality of mounting ends aligned in a third row that is parallel to and offset from the second row.

11 . The electrical connector of claim 9 , wherein:
the first plurality of projections and the second plurality of projections of the assembly housing have distal portions that are wider, in at least one direction, than the plurality of openings of the shield.

12 . The electrical connector of claim 9 , wherein:
the first plurality of openings of the body of the shield comprise a width in a row direction and a first length in a direction perpendicular to the row direction, the second plurality of openings of the body of the shield comprise the width in the row direction and a second length in the direction perpendicular to the row direction, and the second length is longer than the first length.

13 . The electrical connector of claim 9 , wherein:
the assembly housing comprises a plurality of openings having portions of the intermediate portions of the plurality of conductive elements exposed therethrough, and the exposed portions of the intermediate portions of the plurality of conductive elements exposed therethrough are wider than unexposed portions of the intermediate portions of the plurality of conductive elements.

14 . The electrical connector of claim 9 , wherein, for each lead assembly:
the assembly housing comprises a first portion holding first segments of the plurality of conductive elements and a second portion holding second segments of the plurality of conductive elements, the first portion of the assembly housing comprises the first plurality of projections, and the second portion of the assembly housing comprises the second plurality of projections.

15 . The electrical connector of claim 14 , wherein:
the second portion of the assembly housing comprises a plurality of members, and the shield comprises a third plurality of openings receiving the plurality of members of the second portion of the assembly housing.

16 . The electrical connector of claim 14 , wherein:
the first plurality of openings of the body of the shield is filled by the first plurality of projections, and the second plurality of openings of the body of the shield is partially unfilled.

17 . A method of manufacturing a lead assembly that comprises a plurality of conductive elements each comprising a mating end, a mounting end opposite the mating ends, and an intermediate portion extending between the mating end and the mounting end, and an assembly housing holding the intermediate portions of the plurality of conductive elements, the method comprising:
