Abstract

An example electronic assembly for securing an electronic card. In some forms, the electronic assembly further includes a printed circuit board. The electronic assembly includes a housing having a first set of electrical contacts and a second set of electrical contacts. The housing is configured to receive the electronic card between the first and second set of electrical contacts. The housing further includes a third set of electrical contacts and a fourth set of electrical contacts. The housing is configured to receive the electronic card between the third and fourth set of electrical contacts. A ground shield is positioned between at least one of the first and third set of electrical contacts and the second and fourth set of electrical contacts. In some forms, the ground shield may be positioned between both the first and third set of electrical contacts and the second and fourth set of electrical contacts.

First claim

1 . An electronic assembly for securing an electronic card comprising:
a housing that includes a first set of electrical contacts and a second set of electrical contacts, wherein the housing is configured to receive the card between the first and second set of electrical contacts, wherein the housing further includes a third set of electrical contacts and a fourth set of electrical contacts, wherein the housing is configured to receive the card between the third and fourth sets of electrical contacts; and a ground shield embedded within the housing and positioned between at least one of the first and third sets of electrical contacts and the second and fourth sets of electrical contacts.

2 . The electronic assembly of claim 1 wherein the ground shield includes a first portion between the first and third sets of electrical contacts and a second portion between the second and fourth sets of electrical contacts.

3 . The electronic assembly of claim 2 wherein the first and second sets of electrical contacts are configured to compress the card when the card is positioned between the first and second sets of electrical contacts.

4 . The electronic assembly of claim 3 wherein the third and fourth sets of electrical contacts are configured to compress the card when the card is positioned between the third and fourth sets of electrical contacts.

5 . The electronic assembly of claim 4 further comprising a printed circuit board, wherein the first, second, third and fourth sets of contacts are mounted to conductive pads on the printed circuit board and the first and second portions of the ground shield are mounted to ground pads on the printed circuit board.

6 . The electronic assembly of claim 5 wherein the first, second, third and fourth sets of contacts are each mounted to separate rows of conductive pads on the printed circuit board.

7 . The electronic assembly of claim 6 wherein the rows of conductive pads include opposing ends such that the ground pads on the printed circuit board are adjacent to the opposing ends of the rows of conductive pads.

8 . An electronic assembly for securing an electronic card comprising:
an outer housing that includes a first member having a first set of electrical contacts and a second member having a second set of electrical contacts, wherein the outer housing is configured to receive the card between the first and second sets of electrical contacts; an inner housing that includes a third set of electrical contacts and a fourth set of electrical contacts, wherein the inner housing is configured to receive the card between the third and fourth sets of electrical contacts; and a ground shield embedded within at least one of the inner housing and the outer housing, wherein the ground shield is positioned between at least one of the first and third sets of electrical contacts and the second and fourth sets of electrical contacts.

9 . The electronic assembly of claim 8 wherein the ground shield includes a first portion between the first and third sets of electrical contacts and a second portion between the second and fourth sets of electrical contacts.

10 . The electronic assembly of claim 8 wherein the first and second sets of electrical contacts are configured to compress the card when the card is positioned between the first and second sets of electrical contacts, and wherein the third and fourth sets of electrical contacts are configured to compress the card when the card is positioned between the third and fourth sets of electrical contacts.

11 . The electronic assembly of claim 10 wherein the first member of the inner housing is secured with the outer housing and the second member of the inner housing is secured with the outer housing.

12 . The electronic assembly of claim 11 wherein the first member of the inner housing is molded to the first member of the outer housing and the second member of the inner housing is molded to the second member of the outer housing.

13 - 14 . (canceled)

15 . An electronic assembly for securing an electronic card comprising:
a housing that includes a first set of electrical contacts and a second set of electrical contacts, wherein the housing is configured to receive the card between the first and second sets of electrical contacts, wherein the housing further includes a third set of electrical contacts and a fourth set of electrical contacts, wherein the housing is configured to receive the card between the third and fourth sets of electrical contacts, and wherein the housing further includes a ground shield having a first portion between the first and third sets of electrical contacts and a second portion between the second and fourth sets of electrical contacts: a plurality of first cables that each include a first signal conductor and a first ground conductor, wherein the first signal conductor is electrically connected to the first set of contacts and the first ground conductor is electrically connected to the first portion of the ground shield; a plurality of second cables that each include a second signal conductor, wherein the second signal conductor is electrically connected to the third set of contacts; a plurality of third cables that each include a third signal conductor, wherein the third signal conductor is electrically connected to the fourth set of contacts; and a plurality of fourth cables that each include a fourth signal conductor and a second ground conductor, wherein the fourth signal conductor is electrically connected to the second set of contacts and the second ground conductor is electrically connected to the second portion of the ground shield.

16 . The electronic assembly of claim 15 wherein the ground shield includes a third portion between the third and fourth sets of electrical contacts and a fourth portion between the third and fourth sets of electrical contacts.

17 . The electronic assembly of claim 16 wherein the plurality of second cables includes a third ground conductor that is electrically connected to the third portion of the ground shield.

18 . The electronic assembly of claim 17 wherein the plurality of third cables includes a fourth ground conductor that is electrically connected to the fourth portion of the ground shield.

19 . The electronic assembly of claim 16 wherein the first, second, third and fourth plurality of cables each include an insulating sleeve between the respective signal conductors and the ground conductors.

20 . The electronic assembly of claim 16 wherein the first, second, third and fourth plurality of cables each include an outer insulating layer.
