Abstract

A device and method for reducing crosstalk between wires is provided. The method includes spatially separating first and second sets of wires. A device is disposed relative to the first and second sets of wires to maintain the spatial separation. The method also comprises coupling pins to the first and second sets of wires. Additionally, the method includes covering the device with a connector housing.

Claims

1. A method of manufacturing an electrical cable comprising:

spatially separating a first set of wires from a second set of wires;

disposing an insulative member relative to the first and second sets of wires to maintain complete spatial separation of the first and second set of wires as the first and second set of wires pass through the insulative member;

coupling pins to the first and second sets of wires; and

completely surrounding the insulative member with a separate connector housing.

2. The method of claim 1, wherein disposing the insulative member comprises passing the first set of wires through a first aperture of the insulative member and passing the second set of wires through a second aperture of the insulative member.

3. The method of claim 1, wherein disposing the insulative member comprises disposing the first set of wires in an first open ended aperture on a first side of the insulative member and disposing the second set of wires in a second open ended aperture on a second side of the insulative member.

4. The method of claim 1, wherein disposing the insulative member comprises disposing a conductive piece in between the wires, the conductive piece being coupled to ground.

5. The method of claim 1, wherein disposing the insulative member comprises disposing the wires in a dielectric gel and allowing the gel to cure while the wires are spatially separated.

6. The method of claim 1, comprising stripping the cable to expose the first and second sets of wires.

7. The method of claim 1, wherein completely surrounding the insulative member with a separate connector housing comprises an over-molding process.

8. The method of claim 1, wherein completely surrounding the insulative member with a separate connector housing comprises an assembly of pre-configured components.

9. The method of claim 1, comprising stripping internal electrical isolation insulation from the first set of wires.

10. A method of manufacturing an electrical cable comprising:

spatially separating a first set of wires from a second set of wires;

disposing a device relative to the first and second sets of wires to maintain the spatial separation, wherein disposing the device comprises coupling the first and second sets of wires to the device, wherein the device comprises a printed circuit board;

coupling pins to the first and second sets of wires; and

completely surrounding the device with a separate connector housing.

11. The method of claim 10, comprising coupling the pins to the printed circuit board to electrically couple the first and second sets of wires to the pins.

12. The method of claim 11, wherein coupling the pins to the printed circuit board comprises inserting the printed circuit board in between the pins and soldering the pins to the printed circuit board.

13. A method of manufacturing an electrical cable comprising:

spatially separating a first set of wires from a second set of wires;

disposing a device relative to the first and second sets of wires to maintain the spatial separation, wherein disposing the device comprises coupling the first and second sets of wires to an insulative object, the insulative object having a first set of conductive traces disposed on a first side of the insulative object and a second set of conductive traces disposed on a second side of the insulative object;

coupling pins to the first and second sets of wires; and

completely surrounding the device with a separate connector housing.

14. A method of manufacturing a cable connector comprising:

stripping internal electrical isolation insulation from a first set of wires of a cable;

inserting the first set of wires through a first hole of an insulative member; and

inserting a second set of wires of the cable through a second hole of an insulative member to completely spatially separate the first set of wires from the second set of wires as the first and second set of wires pass through the insulative member;

coupling pins to the first and second sets of wires; and

completely covering the insulative member with a separate connector housing.

15. The method of claim 14, wherein completely covering the insulative member with a separate connector housing comprises an over-molding process.

16. The method of claim 14, wherein stripping the internal electrical isolation insulation from a first set of wires comprises removing a metallic mesh surrounding the first pair of wires.

17. The method of claim 14, comprising stripping insulation surrounding both the first and second sets of wires.

18. The method of claim 17, wherein stripping insulation surrounding both the first and second sets of wires comprises removing a metallic mesh that surrounds both the first and second sets of wires.
