In this case, the clamping element 16 is at least partially elastic, whereby the position of a marginal area of the holding element 16, as indicated in figure 7, can vary at least 2 mm relative to the position of a central area of the holding element 16 at least in the direction perpendicular to the main extension plane of the element of clamping 16. In this way, tolerances can be effectively compensated
de fabricacion del elemento de ferrita 14, en concreto, sin provocar la rotura del material relativamente inelastico del elemento de sujecion 16. Ademas, a pesar de las posibles tolerancias de fabricacion, los elementos de soporte de ferrita 24 estan previstos para presionar al elemento de ferrita 14 contra el soporte de bobina 10 de manera segura.of fabrication of the ferrite element 14, in particular, without causing the relatively inelastic material of the fastening element 16 to break. In addition, despite the possible manufacturing tolerances, the ferrite support elements 24 are provided to press the element of Ferrite 14 against coil holder 10 in a safe manner.
5 Ademas, a traves de los elementos de soporte de ferrita 24 es posible presionar contra el soporte de bobina 10 de manera segura los elementos de ferrita con un espesor de material y/o grosor reducido en comparacion con un espesor de material de referencia y/o grosor de referencia.5 Furthermore, through the ferrite support elements 24 it is possible to press against the coil support 10 the ferrite elements with a reduced material thickness and / or thickness in comparison with a reference material thickness and / or reference thickness.
