Abstract

An automated assembly sensor cable has a generally wide and flat elongated body and a registration feature generally traversing the length of the body so as to identify the relative locations of conductors within the body. This cable configuration facilitates the automated attachment of the cable to an optical sensor circuit and corresponding connector. In various embodiments, the automated assembly sensor cable has a conductor set of insulated wires, a conductive inner jacket generally surrounding the conductor set, an outer jacket generally surrounding the inner jacket and a registration feature disposed along the surface of the outer jacket and a conductive drain line is embedded within the inner jacket. A strength member may be embedded within the inner jacket.

First claim

What is claimed is:

1. An automated assembly sensor cable comprising:
a conductor set of insulated wires comprising a first wire and a second wire;
a drain line;
an inner jacket generally surrounding the conductor set and the drain line, the drain line being configured to drain electrical charge from the inner jacket;
an outer jacket generally surrounding the inner jacket and having a flat outer surface on at least two elongated sides of the outer jacket; and
a machine-readable registration feature configured to facilitate automatic location and attachment of the first wire to a first cable conductor and facilitate automatic location and attachment of the second wire to a second cable conductor different from the first cable conductor.

2. The automated assembly sensor cable according to claim 1 , wherein the conductor set and the drain line are linearly arranged.

3. The automated assembly sensor cable according to claim 1 , wherein the outer jacket and the inner jacket comprise PVC.

4. The automated assembly sensor cable according to claim 3 , wherein the inner jacket comprises co-extruded conductive PVC, and the outer jacket comprises semi-pressure extruded PVC.

5. The automated assembly sensor cable according to claim 3 , wherein the inner jacket is conductive.

6. The automated assembly sensor cable according to claim 1 , wherein the conductor set comprises a pair of emitter wires for transmitting drive currents to sensor LEDs and a pair of detector wires for receiving currents from sensor photodiodes.

7. The automated assembly sensor cable according to claim 1 , wherein a total of four wires are included in the conductor set.

8. The automated assembly sensor cable according to claim 1 , in combination with a connector comprising the first cable conductor and the second cable conductor, the first cable conductor being a first pin and the second cable conductor being a second pin.

9. The automated assembly sensor cable according to claim 1 , in combination with a connector comprising the first cable conductor and the second cable conductor, the first cable conductor being a first pad and the second cable conductor being a second pad.

10. The automated assembly sensor cable according to claim 1 , wherein the drain line is embedded within the inner jacket.

11. The automated assembly sensor cable according to claim 10 , wherein the inner jacket contacts each insulated wire of the conductor set.

12. The automated assembly sensor cable according to claim 1 , wherein the inner jacket separates each insulated wire of the conductor set from the other insulated wires of the conductor set.

13. The automated assembly sensor cable according to claim 1 , wherein the inner jacket has a flat outer surface on at least two elongated sides of the inner jacket.

14. The automated assembly sensor cable according to claim 1 , wherein the drain line is positioned between two insulated wires of the conductor set.

15. The automated assembly sensor cable according to claim 1 , wherein the machine-readable registration feature is configured to be optically sensed to facilitate automatic location and attachment of the first insulated wire to the first cable conductor and facilitate automatic location and attachment of the second insulated wire to the second cable conductor.

16. The automated assembly sensor cable according to claim 1 , wherein the machine-readable registration feature comprises a printed indicator.

17. The automated assembly sensor cable according to claim 16 , wherein the printed indicator comprises a line.

18. The automated assembly sensor cable according to claim 1 , wherein the machine-readable registration feature extends along a length of the automated assembly sensor cable.

19. The automated assembly sensor cable according to claim 1 , wherein the machine-readable registration feature is configured to facilitate automatic detection of an orientation of the outer jacket.

20. The automated assembly sensor cable according to claim 1 , wherein the conductor set comprises a plurality of first wires and a plurality of second wires,
wherein the plurality of first wires, the drain line, and the plurality of second wires are linearly arranged, and
wherein a first spacing between the plurality of first wires is the same as a second spacing between the plurality of second wires.
