Abstract

Cable assemblies for providing electrical communication between hinged sections of an electronic device are described. The cable assemblies can include a cover that covers one or more cables that run through a hinge region of the electronic device. The cable and cover can be drawn over a mandrel of the hinge region. The cover and the portions of the mandrel can be visible to a user at the hinge region of the electronic device. The cover can be sufficiently rigid to guide a path of the cable and protect the cable from bending beyond a prescribed angle during rotation of the electronic device at the hinge region. The cover can also be sufficiently rigid to prevent ceasing or folding of the cover and the cable during rotation of the electronic device at the hinge region.

First claim

What is claimed is:

1. An electronic device, comprising:
a first housing including a mandrel surface;
a second housing;
a hinge coupling the first housing and the second housing, the mandrel surface being located at the hinge;
a cable routed from the first housing to the second housing, wherein the cable has an inner surface, wherein a portion of the mandrel surface is compressible from a first shape to a second shape while a particle is positioned between the mandrel surface and the inner surface of the cable.

2. The electronic device of claim 1 , further comprising a cover positioned between the cable and the second housing.

3. The electronic device of claim 2 , further comprising a tensioning mechanism positioned in the second housing and attached to the cover.

4. The electronic device of claim 1 , wherein the cable is bendable to furl and unfurl relative to the mandrel surface.

5. The electronic device of claim 1 , wherein the portion of the mandrel surface is configured to evenly distribute compression forces or pressure of the particle against the mandrel surface.

6. The electronic device of claim 1 , wherein the particle is substantially flush with a second portion of the mandrel surface while the portion of the mandrel surface is compressed into the second shape.

7. The electronic device of claim 1 , wherein the portion of the mandrel is configured to resume the first shape after being compressed to the second shape.

8. The electronic device of claim 1 , wherein the inner surface of the cable is spaced away from the mandrel surface by a gap.

9. A computing device, comprising:
an upper housing;
a lower housing coupled to the upper housing via a hinge, wherein a gap is formed between the upper housing and the lower housing;
a cover mounted to the upper housing and movable relative to the upper housing;
wherein when the upper housing is in a closed position relative to the lower housing, the cover is biased against a surface of the lower housing across the gap;
wherein when the upper housing is in an open position relative to the lower housing, the cover is spaced away from the surface of the lower housing.

10. The computing device of claim 9 , further comprising a flexible circuit, wherein the cover bows inwardly toward the flexible circuit.

11. The computing device of claim 9 , wherein the upper housing includes a stop surface, wherein when the upper housing is in the closed position, the stop surface is spaced away from the cover, and wherein when the upper housing is in the open position, the stop surface contacts the cover.

12. The computing device of claim 9 , wherein the cover comprises at least one recess or at least one opening.

13. The computing device of claim 9 , wherein the cover is spaced away from the surface of the lower housing when the upper housing is in the open position in response to the cover being lifted by the upper housing away from the lower housing.

14. The computing device of claim 9 , wherein the surface of the lower housing is recessed relative to an outer surface of the lower housing adjacent to the surface.
