Claim 5:
6. The coil assembly according to claim 1, wherein:
the ring base plate has two opposite large ring surfaces, a circumferential inner lateral surface with respect to the longitudinal centre axis radially inside and a circumferential outer lateral surface with respect to the longitudinal centre axis radially outside, wherein the circumferential outer lateral surface forms the outer edge of the ring base plate,
the counter-ring base plate has two opposite counter-large ring surfaces, a circumferential counter-inner lateral surface with respect to the counter-longitudinal centre axis radially inside and a circumferential counter-outer lateral surface with respect to the counter-longitudinal centre axis radially outside, wherein the circumferential counter-outer lateral surface forms the counter-outer edge of the counter-ring base plate,
a clamping surface provided between two fold-over edge regions of the ring base plate adjacent in the circumferential direction is arranged on a projection projecting in the circumferential direction between the two fold-over outer edge regions and from the outer lateral surface of the ring base plate in the radial direction to the outside, wherein the clamping surface is formed by a front face of the projection pointing in the radial direction to the outside, and
a counter-clamping surface provided between two counter-fold-over outer edge regions of the counter ring base plate adjacent in the counter-circumferential direction is arranged on a counter-projection projecting in the counter-circumferential direction between the two counter-fold-over outer edge regions and in the radial direction from the counter-outer lateral surface of the counter-ring base plate, wherein the counter-clamping surface is formed by a front face of the counter-projection pointing in the radial direction to the outside.
