twisting together the first end of the second wire with the second end of the first wire; and
twisting together the first end of the third wire with the second end of the fourth wire.
5. The connector as recited in claim 3 , wherein the wires comprise four pairs of twisted wires.
6. The connector as recited in claim 3 , wherein the core is a first core and the connector further comprises a common mode choke device formed by the steps of:
inserting two of the wires through a third hole in a second core;
wrapping the two of the wires around a side of the second core; and
inserting the two of the wires through a fourth hole of the second core, the fourth hole of the second core being spaced from the third hole of the second core and having a longitudinal axis extending parallel to a longitudinal axis of the third hole.
7. The connector as recited in claim 6 , wherein each wire has a first end and a second end, the first end not being inserted through the first core, the second end coming out from the second hole of the first core, and wherein the electric device is further formed by:
twisting together the first end of the first wire with the second end of the second wire;
twisting together the first end of the second wire with the second end of the first wire; and
twisting together the first end of the third wire with the second end of the fourth wire.
8. The connector as recited in claim 7 , wherein the two of the wires include the second end of the third wire and the first end of the fourth wire.
9. The connector as recited in claim 6 , wherein the common mode choke device is further produced by repeating the steps of inserting two of the wires, wrapping the two of the wires, and inserting the two of the wires, a desired number of times.
10. A connector for enabling electrical communication with a plug, the connector comprising:
at least one contact effective to communicate with a terminal of a plug;
a magnetic filter circuit in communication with the contact; and
a terminal in communication with the magnetic filter circuit; wherein
the magnetic filter circuit includes an electric device, the electric device including a core, the core having a first hole with a first longitudinal axis and a second hole spaced from the first hole, the second hole having a second longitudinal axis parallel to the first longitudinal axis, the core including at least one wire inserted through the first hole, wrapped around a side of the core and inserted through the second hole.
11. The connector as recited in claim 10 , wherein the at least one wire is inserted through the first hole, wrapped around the side of the core, and inserted through the second hole a desired number of times.
12. A method for producing a connector for enabling electrical communication with a plug, the method comprising:
inserting at least one wire through a first hole of a core,
wrapping the at least one wire around a side of the core;
inserting the at least one wire through a second hole of the tore to form an electric device, the second hole of the core being spaced from the first hole and having a longitudinal axis extending parallel to a longitudinal axis of the first hole;
coupling the electric device to at least one terminal; and
coupling the electric device to at least one contact.
13. The method as recited in claim 12 , wherein the electric device is further formed by repeating the steps of inserting at least one wire, wrapping, and inserting the at least one wire a desired number of times.
14. The method as recited in claim 12 , where the at least one wire comprises a first, second, third and fourth wire.
15. The method as recited in claim 14 , wherein each wire has a first end and a second end, the first end not being inserted through the core, the second end coming out from the second hole of the core, and wherein the electric device is further formed by:
twisting together the first end of the first wire with the second end of the second wire;
twisting together the first end of the second wire with the second end of the first wire; and
twisting together the first end of the third wire with the second end of the fourth wire.
