At least one electrical connection exists between the conductor and an electrical contact region arranged at an adjoining region of the gradient coil unit. The electrical connection is formed by a flexible circuit board that is electrically connected both with the conductor and with the contact region. Such an electrical connection of the antenna rod is insensitive to strong vibrations.

摘要： A magnetic resonance apparatus with a radio-frequency shield at a reference potential, a detuning circuit and an electrical line which is connected with the detuning circuit. The electrical line is fashioned as a strip conductor and is attached to the radio-frequency shield. The strip conductor can be used for direct icurrent/direct voltage supply of the detuning circuit. This has the advantage that the detuning circuit can be activated without exerting a significant interfering influence on the magnetic field in the magnetic resonance apparatus.
