Drill string transmission line
First Claim
1. A transmission line assembly for transmitting information along a downhole tool, the downhole tool comprising a pin end, a box end, and a central bore traveling between the pin end and the box end, the transmission line assembly comprising:
- a protective conduit;
a transmission line routed through the protective conduit;
the protective conduit being further routed through the central bore, the ends thereof being routed through channels formed in the pin end and box end; and
the protective conduit being further elastically forced into a non-linear path through the central bore by elastically confining the protective conduit to a length within the central bore shorter than the protective conduit wherein the diameter of the protective conduit is narrowed to provide improved contact between the protective conduit and the transmission line.

Abstract
A transmission line assembly for transmitting information along a downhole tool comprising a pin end, a box end, and a central bore traveling between the pin end and the box end, is disclosed in one embodiment of the invention as including a protective conduit. A transmission line is routed through the protective conduit. The protective conduit is routed through the central bore and the ends of the protective conduit are routed through channels formed in the pin end and box end of the downhole tool. The protective conduit is elastically forced into a spiral or other non-linear path along the interior surface of the central bore by compressing the protective conduit to a length within the downhole tool shorter than the protective conduit.

9. A method for routing a transmission line assembly through a drill tool having a pin end, a box end, and a central bore traveling between the pin end and the box end, the method comprising:
-
providing a protective conduit; routing a transmission line through the protective conduit; narrowing the diameter of the protective conduit to provide improved contact between the protective conduit and the transmission line; routing the protective conduit through the central bore, the ends thereof being routed through channels formed in the pin end and box end; and forcing the protective conduit to take a non-linear path through the central bore by elastically forcing the protective conduit to fit within a length of the central bore shorter than the protective conduit. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for forming a transmission line assembly for routing through a drill tool living a pin end, a box end, and a central bore traveling between the pin end and the box end, the method comprising:
-
providing a protective conduit; routing a transmission line through the protective conduit; narrowing the diameter of the protective conduit to provide improved contact between the conduit and the transmission line; and routing the protective conduit through the drill tool such that it substantially spirals elastically around the interior surface of the central bore, the ends thereof being routed through channels formed in the pin end and box end. - View Dependent Claims (18)
