A cable for operating a gradient coil of a magnetic resonance apparatus, the cable comprising:
- at least one electric conductor configured to enable a current flow between the gradient coil and a current source of the gradient coil;
- and
- a stabilizing sheathing that surrounds the at least one electric conductor at least partially,
- wherein the stabilizing sheathing has at least one connecting portion parallel to a longitudinal axis of the cable, the at least one connecting portion being configured to provide a connection between the at least one electrical conductor and the stabilizing sheathing, and
- wherein a first outer surface of the stabilizing sheathing is radially inner relative to a second outer surface of the stabilizing sheathing, the first outer surface of the stabilizing sheathing being an outer surface of a connecting portion of the at least one connecting portion.
A magnetic resonance apparatus comprising:
- at least one cable for operating a gradient coil of the magnetic resonance apparatus, a cable of the at least one cable comprising:
- at least one electric conductor configured to enable a current flow between the gradient coil and a current source of the gradient coil;
- and
- a stabilizing sheathing that surrounds the at least one electric conductor at least partially,
- wherein the stabilizing sheathing has at least one connecting portion parallel to a longitudinal axis of the cable, the at least one connecting portion being configured to provide a connection between the at least one electrical conductor and the stabilizing sheathing, and
- wherein a first outer surface of the stabilizing sheathing is radially inner relative to a second outer surface of the stabilizing sheathing, the first outer surface of the stabilizing sheathing being an outer surface of a connecting portion of the at least one connecting portion.
A method for manufacturing a cable for operating a gradient coil of a magnetic resonance apparatus, the method comprising:
- introducing at least one electric conductor into a stabilizing sheathing, the at least one electric conductor being configured to enable a current flow between the gradient coil and a current source of the gradient coil, wherein the stabilizing sheathing has at least one connecting portion parallel to a longitudinal axis of the cable, the at least one connecting portion being configured to provide a connection between the at least one electrical conductor and the stabilizing sheathing, and wherein a first outer surface of the stabilizing sheathing is radially inner relative to a second outer surface of the stabilizing sheathing, the first outer surface of the stabilizing sheathing being an outer surface of a connecting portion of the at least one connecting portion;
- and
- creating at least one form-fitting connection between the stabilizing sheathing and the at least one electric conductor.
The method as claimed of 16, wherein the form-fitting connection is created by crimping, hot-forming, or crimping and hot-forming.
