Abstract

A cable harness for passing one or more cables through an opening the wall includes a cable conduit including a generally S-shaped channel defined by an inner surface of a first shell portion and an inner surface of a second shell portion attached to the first shell portion and a least one cable disposed in the cable conduit. A method of mounting a cable relative to an opening in a wall is also disclosed.

Claims

1. A cable conduit for passing, supporting, and guiding one or more cables through an opening in a wall, comprising:

a first shell having a first end and an opposite second end; and

,

a second shell having a first end and an opposite second end;

the second shell being attachable along its length to the first shell with the first end of the second shell mating with the second end of the first shell, inner surfaces of the first shell and second shell defining a generally S-shaped channel having a first end portion laterally offset from a second end portion, central axes of the first end portion and the second end portion lying in parallel planes and joined by a central portion oblique to the first end portion and second end portion,

the first shell including at the first end an outwardly extending first shell mounting flange parallel to the central axis of the first end portion, wherein the first shell mounting flange is attachable to a wall at an opening in the wall so that S-shaped channel traverses the opening with the central portion disposed in the opening.

2. The cable conduit as set forth in claim 1, wherein the central axes of the first end portion of the channel and the second end portion of the channel are parallel.

3. The cable conduit as set forth in claim 1, the second shell further comprising a second shell mounting flange extending from the second shell and parallel to the first shell mounting flange, the second shell mounting flange being attachable to a wall.

4. The cable conduit as set forth in claim 3, wherein the first shell mounting flange and the second shell mounting flange are disposed in a common plane and are attachable to a common wall surface.

5. The cable conduit as set forth in claim 1, comprising at least one wrapping member for securing at least one cable in a portion of the channel defined by one of the first shell and the second shell.

6. The cable conduit as set forth in claim 5, wherein the at least one wrapping member extends through holes extending through the portion of the channel.

7. The cable conduit as set forth in claim 5, comprising insulation inside the channel.

8. The cable conduit as set forth in claim 7, wherein the insulation is disposed at least proximate end portions of the channel.

9. The cable conduit as set forth in claim 1, comprising a plurality of wrapping members for securing one or more cables in the portion of the channel defined by one of the first shell and the second shell.

10. The cable conduit as set forth in claim 1, comprising insulation inside the channel,

11. The cable conduit as set forth in claim 10, wherein the insulation is disposed at least proximate end portions of the channel.

12. The cable conduit as set forth in claim 1, wherein the first and second shell portions are identical.

13. A method of mounting a cable relative to an opening in a wall, comprising:

providing a cable conduit comprising a first shell having an inner surface and a second shell having an inner surface, the second shell attachable along its length to the first shell to define a generally S-shaped channel, the S-shaped channel having a first end portion, a second end portion laterally offset and parallel to the first end portion, and a central portion oblique to the first end portion and second end portion, the cable conduit having at least one flange attachable to a wall;

positioning at least one cable in the S-shaped channel;

positioning the cable conduit relative to an opening in a wall with the first end portion on one side of the wall and the second end portion on an opposite side of the wall, and the central portion extending through the opening, the flange being in mounting contact with the wall and a first end of the cable disposed on one side of the wall and a second end of the cable is disposed on an opposite side of the wall.

14. The method of mounting set forth in claim 13, comprising fastening the flange to the wall.

15. The method of mounting set forth in claim 13, wherein the cable conduit is partially extended through the opening subsequent to positioning the at least one cable in the S-shaped channel.

16. The method of mounting set forth in claim 13, wherein the at least one flange is formed on the first shell at the first end parallel to a central axis of the first end portion.
