Abstract

A connection of a connection wire and a connection element are disclosed. In an embodiment a connection includes a connection wire having an insulation and a stud-shaped metallic connection element, wherein the connection wire is wound in a plurality of turns around the connection element, and wherein the turns include a first wire section, in which the connection wire is insulation-stripped, and a second wire section, in which the insulation is present.

First claim

The invention claimed is:

1. A connection comprising:
a connection wire having an insulation;
a stud-shaped metallic connection element,
wherein the connection wire is wound in a plurality of turns around the connection element, and
wherein the turns comprise a first wire section, in which the connection wire is insulation-stripped, and a second wire section, in which the insulation is present; and
a solder covering all turns in the first wire section,
wherein the insulation is a high-temperature-resistant wire insulation, and
wherein the high-temperature-resistant wire insulation remains stable when the connection wire is soldered or welded to the connection element.

2. The connection according to claim 1 , wherein the first and the second wire sections each comprises one turn.

3. The connection according to claim 1 , wherein the first wire section is soldered or welded to the connection element.

4. The connection according to claim 1 , wherein the connection element is connected to an electrical component by the connection wire, wherein the turns are arranged in a row around the connection element, wherein one turn of the second wire section is arranged at an end of the row of turns at which the connection wire is routed out from the connection element to the electrical component.

5. The connection according to claim 4 , wherein the electrical component is an inductance.

6. The connection according to claim 4 , wherein the electrical component is a coil.

7. The connection according to claim 1 , wherein the connection wire incorporates copper as a conductor material.

8. The connection according to claim 1 , wherein the insulation-stripped wire section is located at one end of the connection wire.

9. The connection according to claim 1 , wherein the connection wire incorporates aluminum as a conductor material.

10. A connection comprising:
a connection wire having an insulation;
a stud-shaped metallic connection element,
wherein the connection wire is wound in a plurality of turns around the connection element, and
wherein the turns comprise a first wire section, in which the connection wire is insulation-stripped, and a second wire section, in which the insulation is present; and
a solder covering at least one full turn in the first wire section,
wherein the insulation is a high-temperature-resistant wire insulation, and
wherein the high-temperature-resistant wire insulation remains stable when the connection wire is soldered or welded to the connection element.

11. The connection according to claim 10 , wherein the first and the second wire sections each comprises one turn.

12. The connection according to claim 10 , wherein the first wire section is soldered or welded to the connection element.

13. The connection according to claim 10 , wherein the connection element is connected to an electrical component by the connection wire, wherein the turns are arranged in a row around the connection element, wherein one turn of the second wire section is arranged at an end of the row of turns at which the connection wire is routed out from the connection element to the electrical component.

14. The connection according to claim 13 , wherein the electrical component is an inductance.

15. The connection according to claim 13 , wherein the electrical component is a coil.

16. The connection according to claim 10 , wherein the connection wire incorporates copper as a conductor material.

17. The connection according to claim 10 , wherein the insulation-stripped wire section is located at one end of the connection wire.

18. The connection according to claim 10 , wherein the connection wire incorporates aluminum as a conductor material.
