Patent ID: 6900715

Claim:
A fastening device for fastening a toroidal choking coil to a base or the like, the toroidal choking coil comprising: an inner circumference defined by a surface parallel with an axis of rotation of the toroidal choking coil and located closest to the axis of rotation; an outer circumference defined by a surface parallel with the axis of rotation of the toroidal choking coil and located outermost from the axis of rotation, and; side surfaces defined by surfaces perpendicular to the axis of rotation of the toroidal choking coil and connecting the inner circumference and the outer circumference, the fastening device comprising at least one pair of choking coil fasteners, comprising: a first choking coil fastener and a second choking coil fastener, arranged to be installed on opposite side surfaces of the toroidal choking coil, and that at least one choking coil fastener is arranged to come at least partly into contact with the outer circumference of the toroidal choking coil and at least one choking coil fastener is arranged to come at least partly into contact with the inner circumference of the toroidal choking coil, wherein each choking coil fastener comprises branches as viewed in a direction of rotation of the toroidal choking coil, and the fastening device further comprises a pair of connecting devices comprising a first connecting device and a second connecting device which, interconnected, are arranged to subject at least one pair of choking coil fasteners to forces that are parallel with the axis of rotation of the toroidal choking coil and directed toward a center of the toroidal choking coil, enabling the toroidal choking coil to be squeezed between the at least one pair of choking coil fasteners.
