Abstract
With regard to safe and long-term use of a coil arrangement with structurally simple means, a coil arrangement (1), in particular for use as an inductor, and in an embodiment for inductive sensors and eddy current sensors, with a winding body (3) and at least one coil wound on the winding body (3). or windable coil (2), is designed and developed in such a way that the winding body (3) has at least one resilient or elastic element (8, 8′) and/or at least one resilient or elastic region for at least partial compensation of different thermal expansions and/or contractions of the winding body (3) and the coil (2).
Claims3
A coil arrangement (1), for use as an inductor with inductive sensors and eddy current sensors, comprising:
- a circular-cylindrical winding body (3);
- and
- a coil (2) that is wound onto the winding body (3),
- wherein the winding body (3) is configured such that the winding body (3) has
- at least one resilient or elastic region for at least partial compensation of different thermal expansions and/or contractions of the winding body (3) and the coil (2),
- wherein the at least one resilient or elastic region is formed by at least one slot (4, 4″) in the winding body (3) and by a circumferential groove (9) in the winding body (3),
- wherein the at least one slot (4, 4) extends in an axial direction of the winding body (3) into an interior formed by said coil (2) and through the winding body (3) along an axis (5) of the winding body (3),
- wherein by the at least one slot, segments (6) are formed in the winding body (3), which form resilient elements (8) in a radial direction (7), and
- wherein the groove (9) is formed inside the coil (2) with its width in the radial direction, whereby between the groove and the coil a circumferential web 10, interrupted by the at least one slot and consisting of resilient elements (8′), is formed.
