Abstract

Contact structures that are readily manufactured, where contacts in the contact structures consume a minimal amount of surface area, depth, and volume in an electronic device.

First claim

What is claimed is:

1. An electronic device comprising:
a device enclosure having a plurality of openings;
a plurality of electrical contacts, each electrical contact located in a corresponding one of the plurality of openings in the device enclosure such that a gap exists between an outside edge of each contact and an inside edge of the corresponding opening in the device enclosure, each electrical contact having a contacting surface for mating with a contact on a corresponding device when the electronic device and corresponding device are mated;
a housing comprising a plurality of insulating rings, each of the plurality of insulating rings filling the gap between the outside edge of an electrical contact and the inside edge of the corresponding opening in the device enclosure, the housing further comprising a plurality of alignment features on a back side; and
a flexible circuit board attached to the back side of the housing, the flexible circuit board comprising a plurality of openings, each opening to align with a corresponding alignment feature.

2. The electronic device of claim 1 wherein each of the plurality of electrical contacts are soldered to the flexible circuit board.

3. The electronic device of claim 2 further comprising a bracket positioned such that the plurality of electrical contacts are between the bracket and the device enclosure.

4. The electronic device of claim 3 wherein the bracket comprises fastener openings at opposing ends, and further comprising a plurality of fasteners, each passing through a corresponding fastener opening and into a corresponding fastener opening in the device enclosure.

5. The electronic device of claim 1 wherein the contacting surface of each of the plurality of electrical contacts is flat and is at least substantially flush with an outside surface of the device enclosure.

6. The electronic device of claim 1 wherein the contacting surface of each of the plurality of electrical contacts is at least substantially flush with an outside surface of the device enclosure.

7. The electronic device of claim 1 wherein the flexible circuit board is attached to the housing using an adhesive.

8. An electronic device comprising:
a device enclosure having a plurality of openings;
a plurality of electrical contacts, each electrical contact located in a corresponding one of the plurality of openings in the device enclosure, each electrical contact having a contacting surface for mating with a contact on a corresponding device when the electronic device and corresponding device are mated;
a housing comprising a plurality of insulating rings, each insulating ring between a contact and the device enclosure, the housing further comprising a plurality of alignment features on a back side; and
a flexible circuit board attached to the back side of the housing, the flexible circuit board comprising a plurality of openings, where each of the alignment features pass through a corresponding opening in the plurality of openings in the flexible circuit board.

9. The electronic device of claim 8 further comprising a bracket positioned such that the plurality of electrical contacts are between the bracket and the device enclosure.

10. The electronic device of claim 9 further comprising a silicone gasket between the housing and the device enclosure.

11. The electronic device of claim 8 wherein the contacting surface of each of the plurality of electrical contacts is at least substantially flush with an outside surface of the device enclosure.

12. The electronic device of claim 8 wherein the contacting surface of each of the plurality of electrical contacts is flat and is at least substantially flush with an outside surface of the device enclosure.

13. An electronic device comprising:
a device enclosure having a plurality of openings;
a plurality of electrical contacts, each electrical contact having a contacting surface on a first side and a contacting portion on a second side opposing the first side, each contacting surface for mating with a contact on a corresponding device when the electronic device and corresponding device are mated, and each electrical contact located in a corresponding one of the plurality of openings in the device enclosure;
a housing comprising a plurality of insulating rings, each insulating ring around an outside of a corresponding one the plurality of electrical contacts, wherein the housing fits in a recess in the device enclosure;
a bracket having fastener openings at opposing ends;
a flexible circuit board attached to a rear surface of the housing such that the flexible circuit board is between the housing and the bracket; and
a plurality of fasteners, each passing through a corresponding fastener opening in the bracket and into a corresponding fastener opening in the device enclosure.

14. The electronic device of claim 13 wherein the housing is formed of plastic.

15. The electronic device of claim 14 further comprising a seal between the housing and the device enclosure, wherein the seal is a gasket.

16. The electronic device of claim 15 wherein the flexible circuit board is attached to contacting portions of each of the plurality of electrical contacts, and wherein the flexible circuit board is attached to the housing using a heat-activated film.

17. The electronic device of claim 16 wherein the housing further comprises a plurality of posts and wherein the flexible circuit board comprises a plurality of openings, each of the posts extending through a corresponding one of the openings in the flexible circuit board.

18. The electronic device of claim 17 further comprising a shim between the housing and the device enclosure.

19. The electronic device of claim 13 wherein the contacting surface of each of the plurality of electrical contacts is at least substantially flush with an outside surface of the device enclosure.

20. The electronic device of claim 13 wherein the contacting surface of each of the plurality of electrical contacts is flat and is at least substantially flush with an outside surface of the device enclosure.
