Magnetic core device, has spacer comprising elastic strip and two ends that are connected with one another by using welded joint, where spacer comprises height that corresponds to nominal height of coil

摘要

The device (100) has a core (101) e.g. ring core, and a spacer (102) comprising an elastic strip. The spacer has two ends (120, 130) that are connected with one another by using a welded joint (110), where the strip is a self-adhesive strip. The spacer comprises a height that corresponds to a nominal height of a coil that is arranged on the device, and has a width, which correlates with a tension strain desired value for the coil, where the spacer is manufactured from a hardening material e.g. adhesive material.
