Abstract
Abstract A mounting for an especially current-compensated ferrite ring core choke, includes an insulating material plate, and a potential-isolating device, the potential-isolating device including straps fastened upright on the insulating material plate, and a resilient ring interconnecting the straps, the straps having inner edges facing each other and outer edges, the ferrite ring core choke being slipped on the potential-isolating device with the outer edges of the straps resting resiliently against the ferrite ring core and windings on different sections of the ring core physically separated from each other.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
Mounting and current-compensated ferrite ring core choke, comprising an insulating material plate, and a potential-isolating device, said potential-isolating device including straps fastened upright on said insulating material plate, and a resilient ring interconnecting said straps, said straps having inner edges facing each other and outer edges, the ferrite ring core choke being slipped on said potential-isolating device with said outer edges of said straps resting resiliently against the ferrite ring core and windings on different sections of the ring core physically separated from each other.
Claim 2
Dependent Claim
85 words
Mounting and current-compensated ferrite ring core choke, comprising an insulating material plate, and a potential-isolating device, said potential-isolating device including straps fastened upright on said insulating material plate, and a resilient ring interconnecting said straps, said straps having inner edges facing each other and outer edges, the ferrite ring core choke being slipped on said potential-isolating device with said outer edges of said straps resting resiliently against the ferrite ring core and windings on different sections of the ring core physically separated from each other.
Claim 3
Dependent Claim
36 words
Mounting and current-compensated ferrite ring core choke according to claim 1, wherein said insulating material plate has cutouts formed therein defining resilient bracket elements between said cutouts, said straps being connected to said resilient bracket elements.
Claim 4
Dependent Claim
26 words
Mounting and current-compensated ferrite ring core choke according to claim 2, wherein said insulating material plate, said straps and said ring are integral with each other.
Claim 5
Dependent Claim
27 words
Mounting and current-compensated ferrite ring core choke according to claim 1, wherein said straps are in the form of two co-planar straps interconnected by said resilient ring.
Claim 6
Dependent Claim
45 words
Mounting and current-compensated ferrite ring core choke according to claim 1, wherein said straps are in the form of at least three straps disposed equidistant from the longitudinal central axis of said potential-isolating device, said straps having inner edges being interconnected by said resilient ring.
Claim 7
Dependent Claim
41 words
Mounting and current-compensated ferrite ring core choke according to claim 1, wherein said outer edges of said straps define the outer periphery of said potential-isolating device and rest resiliently against opposite surfaces defining a hole formed in the ferrite ring core.
Claim 8
Dependent Claim
54 words
Mounting and current-compensated ferrite ring core choke according to claim 1, wherein said straps have end surfaces facing away from said insulating material plate, and one of said straps is wider than the other of said straps at least at said end surface thereof, for positioning the windings relative to the ferrite ring core.
