Abstract

A connector for use in connecting a communication element to a transmission line in a wired pipe segment includes a first female end adapted to surround and make electrical contact with a coupler connection that extends away from a communication element of the coupler; a second female end adapted to receive an inner conductor of a coaxial cable; and an inner connection element formed on an inner surface of the connector adapted to electrically connect the coupler connection and the inner conductor, the inner connection element formed such that it does not completely surround at least one of the inner conductor and the coupler connection.

First claim

What is claimed is:

1. A wired pipe segment comprising:
a body extending from a box end to a pin end;
a signal coupler located in one of the box and pin ends, the signal coupler including a communication element and a coupler connection in electrical communication with the communication element and extending away from the communication element;
a transmission line extending away from the coupler towards the other of the box and pin end, the transmission line including an inner conductor surrounded by a dielectric material, the inner conductor extending beyond an end of the dielectric material; and
a hollow connector that electrically connects the coupler to the transmission line, the hollow connector including first and second female ends that respectively receive the inner conductor and a portion of the coupler connection, the hollow connector including and an inner connection element formed on an inner surface of the hollow connector, wherein the inner connection electrically connects the inner conductor and the portion of the coupler connection, wherein the inner connection element is formed such that the inner connection element does not completely surround at least one of the inner conductor and the portion of the coupler connection,
wherein the hollow connector is formed by a first half shell and second half shell joined together; and
wherein the connection element is formed as a conductive strip deposited by laser direct structuring on the first half shell.

2. The wired pipe segment of claim 1 , wherein the first and second half shells are formed of a non-conductive material.

3. The wired pipe segment of claim 1 , wherein the coupler is one of: an inductive coupler, a capacitive coupler, a direct connection and a resonant coupler.

4. An electrical connector for use in connecting a communication element of a signal coupler to an inner conductor of a transmission line in a wired pipe segment, the electrical connector comprising:
a first female end adapted to surround and make electrical contact with a coupler connection of the communication element;
a second female end adapted to receive the an inner conductor; and
an inner connection element formed on an inner surface of the connector adapted to electrically connects the coupler connection and the inner conductor, the inner connection element formed such that the inner connection element does not completely surround at least one of the inner conductor and the coupler connection;
wherein the hollow connector is formed by a first half shell and second half shell joined together; and
wherein the connection element is formed as a conductive strip deposited by laser direct structuring on the first half shell.

5. The connector of claim 4 , wherein the first and second half shells are formed of a non-conductive material.
