Abstract

An electrical connector that includes a housing with an interior cavity configured to receive a card. Electrical contacts are secured across a wall of the housing within the interior cavity and are configured to matingly receive corresponding electrical contacts of the card. The plurality of electrical contacts secured across the wall of the housing are the only electrical contacts of the electrical connector. Each of the plurality of electrical contacts includes a mating interface and the mating interface of each of the plurality of electrical contacts is co-planer. Additionally, the housing includes a card slot opening and each of the plurality of electrical contacts are arranged on one side of the card slot opening.

First claim

What is claimed is:

1. An electrical connector, comprising:
a housing including an interior cavity configured to receive a card, the housing having a top and a bottom, the bottom configured to be mounted to a substrate;
a plurality of electrical contacts secured across a wall of the housing within the interior cavity and configured to matingly receive corresponding electrical contacts of the card;
wherein the plurality of electrical contacts secured across the wall of the housing are the only electrical contacts of the electrical connector;
wherein each of the plurality of electrical contacts includes a mating interface; wherein the mating interface of each of the plurality of electrical contacts is co-planer; and
wherein the housing includes a card slot opening receiving the card and the card slot opening being open at the top of the housing, each of the plurality of electrical contacts are arranged on one side of the card slot opening to mate with one the electrical contacts of the card on one side of the card, the housing configured to receive the card with the card oriented parallel to the bottom of the housing.

2. The electrical connector of claim 1 , wherein the housing is four millimeters or less in height.

3. The electrical connector of claim 1 , wherein the electrical connector is a surface mount technology connector or a through hole socket mount electrical connector.

4. The electrical connector of claim 1 , further comprising a stop element on the wall of the housing and configured to prevent movement of the card.

5. The electrical connector of claim 1 , wherein the wall is a bottom wall of the housing such that the plurality of electrical contacts are configured to be positioned below the card.

6. The electrical connector of claim 5 , wherein the card slot opening is above the bottom wall and configured to receive the card.

7. The electrical connector of claim 1 , further comprising:
a first stop element on the wall of the housing configured to be received by an opening within the card;
a second stop element configured to receive the card; and
a third stop element configured to receive the card.

8. The electrical connector of claim 7 , wherein the housing includes a first sidewall adjacent the first stop element, and a second sidewall adjacent the second stop element.

9. The electrical connector of claim 1 , wherein the plurality of electrical contacts include at least one electrical contact that comprises:
a terminating section configured to engage and extend along a substrate;
a vertical section extending from the terminating section; and
a mating section extending from the vertical section to an arcuate section configured to bias against the card.

10. The electrical connector of claim 9 wherein the substrate is a printed circuit board (PCB).

11. The electrical connector of claim 9 , wherein each of the electrical contacts of the plurality of electrical contacts is the same length.

12. An electrical device comprising:
a substrate having an electrical component mounted to an upper surface of the substrate;
a heat sink coupled to one of the substrate or electrical component to interface with an upper surface of the electrical component to dissipate heat from the electrical component;
an electrical connector mounted to the upper surface of the substrate proximate to the electrical component, the electrical connector including a housing having a plurality of electrical contacts therein being electrically connected to the electrical component through the substrate, the housing having a cavity configured to matingly receive a card, the electrical contacts arranged in the cavity to electrically connect to the card, the electrical contacts electrically connecting the card with the electrical component; and
wherein the electrical connector is coupled to the substrate between the upper surface of the substrate and a bottom of the heat sink to position the card in a space between the upper surface of the substrate and the bottom of the heat sink.

13. The electrical device of claim 12 , wherein the electrical component is an application specific integrated circuit (ASIC) having a bottom surface secured to the substrate and a top surface engaging the heat sink, the ASIC having a height from the bottom surface to the top surface, wherein the height of the electrical connector is equal to or less than the height of the ASIC.

14. The electrical device of claim 12 , wherein the substrate is a printed circuit board (PCB).

15. The electrical device of claim 12 , wherein the electrical connector is four millimeters or less in height.

16. The electrical device of claim 12 , wherein the plurality of electrical contacts include at least one electrical contact that comprises:
a terminating section configured to engage and extend along a substrate;
a vertical section extending from the terminating section; and
a mating section extending from the vertical section to an arcuate section configured to bias against the card.

17. A electrical connector comprising:
a housing including an interior cavity configured to receive a card having a first electrical component on a first surface and a second electrical component on a second surface, the housing including a bottom configured to be mounted to a substrate, the interior cavity receiving the card with the card oriented parallel to the bottom;
a plurality of electrical contacts secured to a wall within the interior cavity of the housing and configured to matingly receive corresponding electrical contacts of the card; and
wherein the housing includes a top wall having a top surface wherein the top surface of the top wall is at or below a plane formed by a top surface of the first electrical component, and wherein the top surface of the top wall is at or above a plane formed by the first surface of the card.

18. The electrical connector of claim 17 , wherein electrical contacts of the plurality of electrical contacts are secured to the top wall of the housing within the interior cavity and electrical contacts of the plurality of electrical contacts are secured to a bottom wall of the housing within the interior cavity.

19. The electrical connector of claim 17 , wherein the electrical connector is a surface mount technology connector or a through hole socket mount electrical connector.

20. The electrical connector of claim 17 , wherein the housing is four millimeters or less in height.
