Abstract

A field installable connector that conforms to standard physical requirements while providing high performance at high speeds. The connector includes a housing holding conductive elements configured for pressure mount to a printed circuit board. The housing has a mating surface, a mounting surface opposite the mating surface in a vertical direction, and a slot extending through the mating surface. Each conductive element has a mating end curving into the slot, and a mounting end extending out of the mounting surface at an angle to the vertical direction. The mounting end has a contact surface configured to make contact with a contact pad on the board. The housing includes holes aligned with holes of the board such that a connecting member can extend through the aligned holes to secure the housing to the board and provide force for sufficient contact between conductive elements and respective contact pads.

First claim

What is claimed is:

1 . An electrical connector, comprising:
a housing comprising a mating surface, a mounting surface separated from the mating surface in a vertical direction, and a slot extending through the mating surface and elongated in a longitudinal direction perpendicular to the vertical direction; and a plurality of conductive elements held in the housing, each of the plurality of conductive elements comprising:
a mating end curving into the slot,
a mounting end extending out of the mounting surface and configured for pressure mount, and
an intermediate portion joining the mating end and the mounting end, wherein, for each of the plurality of conductive elements:
the mounting end extends from the intermediate portion at an angle to the vertical direction; and the angle is greater than zero degrees and less than ninety degrees, wherein the housing comprises a pair of towers disposed at opposite ends of the slot and a pair of latches pivotably attached to respective ones of the pair of towers.

2 . The electrical connector of claim 1 , wherein, for each of the plurality of conductive elements:
the mounting end is thinner and/or narrower than the intermediate portion.

3 . The electrical connector of claim 1 , wherein, for each of the plurality of conductive elements:
the mounting end is thinner than the mating end.

4 . The electrical connector of claim 1 , wherein, for each of the plurality of conductive elements:
the mating end comprises a first curved portion and a second curved portion; the first curved portion joins the second curved portion and the intermediate portion; and the second curved portion comprises a mating contact region in the slot.

5 . The electrical connector of claim 1 , wherein:
for each of the plurality of conductive elements, the mounting end is thinner and narrower than the intermediate portion.

6 . The electrical connector of claim 1 , wherein:
each of the pair of towers comprises a lug extending outwards of the slot and comprising a mounting hole extending therethrough.

7 . The electrical connector of claim 6 , wherein:
the housing comprises another mounting hole disposed between the pair of towers.

8 . The electrical connector of claim 1 , wherein:
the housing comprises one or more mounting holes; and the electrical connector comprises a member comprising one or more mounting holes aligned with respective ones of the one or more mounting holes of the housing.

9 . The electrical connector of claim 8 , wherein:
the member comprises a pair of openings; and the housing comprises a pair of towers disposed at opposite ends of the slot and extending through respective ones of the pair of openings and in the vertical direction.

10 . An electrical connector, comprising:
a housing comprising:
a mating surface,
a mounting surface separated from the mating surface in a vertical direction,
a slot extending through the mating surface and elongated in a longitudinal direction perpendicular to the vertical direction, and
one or more mounting holes;
a plurality of conductive elements held in the housing, each of the plurality of conductive elements comprising a mating end curving into the slot and a mounting end extending out of the mounting surface; and a member at least partially disposed on the housing and comprising:
a slot aligned with the slot of the housing, and
one or more mounting holes aligned with respective ones of the one or more mounting holes of the housing, wherein:
the member comprises a pair of openings; and the housing comprises a pair of towers disposed at opposite ends of the slot and extending through respective ones of the pair of openings and in the vertical direction.

11 . The electrical connector of claim 10 , wherein:
the one or more mounting holes of the member comprise a first mounting hole disposed outside the pair of towers and a second mounting hole disposed between the pair of towers.

12 . The electrical connector of claim 10 , wherein:
the member comprises material stronger than material of the housing.

13 . The electrical connector of claim 10 , wherein, for each of the plurality of conductive elements:
the mounting end extends from an intermediate portion at an angle to the vertical direction; and the angle is greater than zero degrees and less than ninety degrees.

14 . The electrical connector of claim 13 , wherein:
the mounting end comprises a contact surface perpendicular to the vertical direction.

15 . The electrical connector of claim 14 , wherein:
the contact surface comprises a conductive layer.

16 . The electrical connector of claim 10 , wherein:
the member comprises a first portion disposed on the mating surface; and the first portion of the member comprises the slot of the member.

17 . The electrical connector of claim 16 , wherein:
the member comprises a second portion extending from the first portion and in the vertical direction.

18 . An electronic system, comprising:
a printed circuit board comprising a memory bus; a first electrical connector electrically coupled to the memory bus; a second electrical connector disposed next to the first electrical connector and electrically coupled to the memory bus; and a connecting member holding both the first electrical connector and the second electrical connector to the printed circuit board, wherein: the connecting member extends through a hole; the first electrical connector comprises a first housing comprising a first portion of the hole; and the second electrical connector comprises a second housing comprising a second portion of the hole.

19 . The electronic system of claim 18 , wherein:
the first electrical connector comprises a first housing and a first member at least partially disposed on the first housing; and the connecting member holds the first member of the first electrical connector to the printed circuit board.

20 . The electronic system of claim 19 , wherein:
the second electrical connector comprises a second housing and a second member at least partially disposed on the second housing; and the connecting member holds the second member of the second electrical connector to the printed circuit board.
