Abstract

This application relates to cable assemblies with an outer (exterior) layer formed from braiding materials together. To achieve a desired pattern, a machine tool forming the outer layer undergoes several modifications. For a machine tool with two tracks (e.g., inner and outer track) with multiple carriers of material to be braided, each carrier position may include multiple bobbins, with each bobbin carrying a spool/coil of the material. During a braiding operation performed by the machine tool, each track rotates in opposite directions. Moreover, some bobbins include an arm that guides the material in a particular manner. For example, during rotation of the track, the arm provides a swinging motion, causing the material carried by the arm to move in a periodic (e.g., sinusoidal) motion. An additional track may be used to guide the arms.

First claim

What is claimed is:

1. A cable assembly, comprising:
a first connector;
a second connector;
a cord extending between the first connector and the second connector, the cord configured to provide power and data transmission from the first connector to the second connector, the cord comprising:
an outer layer, the outer layer comprising:
a first set of strands, wherein each strand of the first set of strands comprises a circular cross section,
a second set of strands adjacent to the first set of strands, and
a third set of strands weaved with the first set of strands and the second set of strands;

an insulated wire electrically connected to the first connector and the second connector;
an uninsulated wire electrically connected to the first connector and the second connector, wherein the insulated wire and the uninsulated wire are configured to provide the power and data transmission from the first connector to the second connector; and
a fill material between the insulated wire and the uninsulated wire, wherein the fill material contacts the insulated wire and the uninsulated wire.

2. The cable assembly of claim 1 , wherein the first set of strands and the second set of strands includes yarn.

3. The cable assembly of claim 1 , wherein each of the first set of strands, the second set of strands, and the third set of strands includes two strands.

4. The cable assembly of claim 1 , wherein each of the first set of strands, the second set of strands, and the third set of strands includes exactly two strands.

5. The cable assembly of claim 1 , wherein the first set of strands is parallel with respect to the second set of strands.

6. The cable assembly of claim 1 , wherein the outer layer defines an exterior of the cord.

7. The cable assembly of claim 1 , wherein:
the first connector is configured to plug into an electronic device, and
the second connector is configured to plug into a power adapter.

8. A cable assembly, comprising:
a first connector;
a second connector; and
a cord extending between the first connector and the second connector, the cord comprising an outer layer, the outer layer comprising:
a first pair of strands,
a second pair of strands adjacent to the first pair of strands, and
a third of pair strands, wherein the third pair of strands passes over the first pair of strands and passes under the second pair of strands;
a plurality of insulated wires electrically connected to the first connector and the second connector;
a plurality of uninsulated wires electrically connected to the first connector and the second connector, wherein the plurality of insulated wires and the plurality of uninsulated wires are configured to provide power and data transmission from the first connector to the second connector; and
a fill material between the plurality of insulated wires and the plurality of uninsulated wires, wherein the fill material contacts i) each insulated wire of the plurality of insulated wires and ii) each uninsulated wire of the plurality of uninsulated wires.

9. The cable assembly of claim 8 , wherein the first pair of strands is parallel with respect to the second pair of strands.

10. The cable assembly of claim 8 , wherein at least one of the first pair of strands, the second pair of strands, and the third pair of strands comprises yarn.

11. The cable assembly of claim 8 , wherein:
the first pair of strands comprises two strands, and
the second pair of strands comprises two strands.

12. The cable assembly of claim 11 , wherein the third pair of strands comprises two strands.

13. A cable assembly, comprising:
a connector;
a cord connected to the connector, the cord comprising an outer layer, the outer layer comprising:
a first set of strands,
a second set of strands parallel to the first set of strands, and
a third of set strands, wherein the third set of strands passes over the first set of strands and passes under the second set of strands;

a plurality of insulated wires electrically connected to the connector;
a plurality of uninsulated wires electrically connected to the connector; and
a fill material between, and in contact with, the plurality of insulated wires and the plurality of uninsulated wires.

14. The cable assembly of claim 13 , wherein the first set of strands is adjacent to the second set of strands.

15. The cable assembly of claim 13 , wherein at least one of the first set of strands, the second set of strands, and the third set of strands comprises yarn.

16. The cable assembly of claim 13 , wherein:
the first set of strands comprises two strands, and
the second set of strands comprises two strands.

17. The cable assembly of claim 16 , wherein the third set of strands comprises two strands.
