Abstract

A twisted pair symmetric bus bar structure for electric power distribution includes a first conductor; a second conductor; an insulator; wherein the first conductor and the second conductor form an interwoven alternating interlocking pattern; wherein the first and second conductors are formed from a series of Z-shaped sections; wherein the insulator is H-shaped and has a series of slots for receiving the first and second conductors; and wherein the insulator is sandwiched between the first and second conductor.

Claims (32)

1. A twisted pair symmetric bus bar structure for electric power distribution, comprising:

a first conductor;

a second conductor;

an insulator;

wherein the first conductor and the second conductor form an interwoven alternating interlocking pattern;

wherein the first and second conductors are formed from a series of Z-shaped sections;

wherein the insulator is H-shaped and has a series of slots for receiving the first and second conductors; and

wherein the insulator is sandwiched between the first and second conductor.

2. The structure of claim 1 , wherein the first and second conductors are formed from a series of modular units with bridging connections; and

wherein the modular units are joined by soldering the bridging connections together when the modular units are arranged in an alternating fashion.

3. The structure of claim 1 , wherein the first and second conductors are individually formed from a single machine stamped conductor.

4. The structure of claim 1 , wherein one or more common mode ferrite members encapsulate portions of the twisted pair symmetric bus bar.

5. The structure of claim 1 , wherein one or more normal mode ferrite members are inserted in slots placed within the insulator and the first and second conductors.

6. The structure of claim 1 , wherein the twisted pair symmetric bus bar has a square cross section.

7. The structure of claim 1 , wherein the twisted pair symmetric bus bar has a rectangular cross section.

8. The structure of claim 1 , wherein the insulator has upward facing wings and downward facing wings that are formed from the series of slots.

9. A method of forming a twisted pair symmetric bus bar, the method comprising:

forming a first conductor;

forming a second conductor;

forming an insulator;

wherein the first and second conductors are formed from a series of modular units with bridging connections;

wherein the modular units are joined by soldering the bridging connections together when the modular units are arranged in an alternating fashion;

wherein the insulator has a series of slots for receiving the bridging connections of the first and second conductors; and

wherein the insulator is sandwiched between the first and second conductors.

10. A method of forming a twisted pair symmetric bus bar, the method comprising:

forming a first conductor;

forming a second conductor;

forming an insulator;

wherein the first and second conductors are individually formed from a single machine stamped conductor;

wherein the insulator has a series of slots for receiving the first and second conductors;

wherein the insulator is sandwiched between the first and second conductors; and

wherein the first and second conductors form an alternating interwoven structure.
