    摘要: Magnetic resonance device with an assembly having a recess, in which a gradient coil unit is attached with at least one attachment means, the attachment means having two members, between which an elastic element is disposed, only one of the members in each instance being in contact with either the gradient coil unit or the assembly, with the attachment means acting as an attachment means having no elastic element in a first attachment state, in which at least a minimum force presses the two members together, in that the two members have stop surfaces, which are in contact with each other due to the minimum force acting on the members compressed elastic element and with the attachment means acting as a spring unit in a second fixing state, in that the elastic element pushes the members apart in the event of forces smaller than the minimum force and causes the attachment means to be fixed in relation to the gradient coil unit and the assembly. This has the advantage that there is no loosening of the attachment means in particular even in the event of thermal fluctuations.

The connection device is fashioned to electrically connect a first gradient current feed line with a second gradient current feed line and is associated with a gradient coil that forms a gradient field via a supplied gradient current for a spatial direction. The supply ensues via the two gradient current feed lines connected with one another. A base plate that is fashioned for fastening the connection plate to a magnet housing of the magnetic resonance apparatus. An electrically insulating layer to damp vibrations of the connection plate is arranged between the base plate and the connection plate.
