Abstract

An electronic device may have a conductive housing. A dielectric structure may be mounted in the conductive housing to form an antenna window. An electrical component such as a camera, light sensor, or other device may press against a conductive foam structure. A printed circuit may have conductive traces that form an antenna ground and antenna resonating element. The printed circuit may be wrapped around a support structure. The electrical component, the conductive foam structure, and the printed circuit wrapped around the support structure may be compressed between a display cover layer and the antenna window. A camera window may be attached to a camera window trim using multiple adhesives. The trim may have a curved exterior surface that matches a curved housing surface. A flexible printed circuit cable may have a folded portion. A band structure may surround the folded portion to form a service loop.

Claims

1. A flex circuit cable assembly, comprising:

a first component;

a second component;

a flexible printed circuit cable having a first end that is coupled to the first component, having a second end that is coupled to the second component, and having a folded portion; and

a band structure that extends around the folded portion of the flexible printed circuit cable to form a service loop in the flexible printed circuit cable.

2. The flex circuit cable assembly defined in claim 1 wherein the band structure is attached to at least some of the flexible printed circuit cable with adhesive.

3. The flex circuit cable assembly defined in claim 2 wherein the band structure has at least one interior surface portion that is free of adhesive so that a layer of the flexible printed circuit cable in the folded portion is free to slide relative to the band structure to adjust the service loop.

4. The flex circuit cable assembly defined in claim 1 wherein the band structure is formed from an elastomeric loop.

5. The flex circuit cable assembly defined in claim 4 wherein the elastomeric loop has an inner surface that surrounds first and second layers of the flexible printed circuit cable in the folded portion and wherein the inner surface is free of adhesive so that both the first and second layers of the flexible printed circuit cable are free to slide relative to the band structure to adjust the service loop.

6. The flex circuit cable assembly defined in claim 1 wherein the band structure is formed from a strip of polymer and wherein a layer of adhesive attaches a first portion of the strip of polymer to a second portion of the strip of polymer.

7. An electronic device, comprising:

a housing having a rectangular periphery and four corners;

a corner bracket in one of the four corners;

a rectangular display cover layer; and

a rectangular ring-shaped gasket that runs around the rectangular periphery and that is interposed between the display cover layer and the housing, wherein the ring-shaped gasket has a portion that is sandwiched between corner bracket and the display cover layer.

8. The electronic device defined in claim 7 wherein the corner bracket has a recess that receives the portion of the ring-shaped gasket.

9. The electronic device defined in claim 7 wherein the ring-shaped gasket comprises an elastomeric polymer.

10. The electronic device defined in claim 7 further comprising an adhesive that attaches the display cover layer to the corner bracket.

11. The electronic device defined in claim 7 wherein the ring-shaped gasket has an L-shaped cross-sectional shape.

12. The electronic device defined in claim 11 wherein the L-shaped cross-sectional shape of the ring-shaped gasket forms a recess and wherein the display cover layer is received within the recess.

13. The electronic device defined in claim 7 wherein the rectangular display cover layer comprises a layer of cover glass.

14. The electronic device defined in claim 7 wherein the corner bracket comprises metal.

15. An electronic device, comprising:

a housing having four corners;

a display cover layer mounted in the housing, wherein the display cover layer has upper and lower opposing surfaces;

an elastomeric gasket that surrounds the display cover layer and that is interposed between the display cover layer and the housing; and

four corner brackets, wherein each corner bracket is attached to the lower surface of the display cover layer in a respective one of the four corners and wherein a portion of the elastomeric gasket extends between the display cover layer and a respective one of the corner brackets.

16. The electronic device defined in claim 15 wherein the respective one of the corner brackets has a recess for accommodating the portion of the elastomeric gasket.

17. The electronic device of claim 15 wherein the corner brackets comprise metal.

18. The electronic device defined in claim 15 wherein the elastomeric gasket has an L-shaped cross sectional shape that forms a recess and wherein the display cover layer is received within the recess.

19. The electronic device defined in claim 15 wherein the elastomeric gasket has a narrowed width at each of the four corners of the housing to accommodate the corner brackets.

20. The electronic device defined in claim 15 further comprising adhesive that attaches each of the corner brackets to the lower surface of the display cover layer.
