Abstract
Abstract A mounting device includes a clamp-like first end portion adapted to engage an upper portion of a ferrite core and toroidal winding combination and an elongated, linear second end portion. Disposed along the length of the second end portion of the mounting device in a spaced manner are a plurality of transverse, flexible fingers. The second end portion of the mounting device is adapted for insertion through an aperture in a printed wiring board (PWB), such that the flexible fingers are deflected upon insertion of the mounting device through the aperture and prevent the removal of the mounting device from the PWB. A double coated foam-type tape or an epoxy glue is disposed between the PWB and a lower portion of the coil/core combination as well as between the first upper end portion of the mounting device and an upper portion of the coil/core combination to protect the toroidal winding from unnecessary contact and possible damage and to maintain the mounted assembly under tension. The portion of the mounting device extending through and beyond the PWB is cut away prior to wave soldering of the ends, or leads, of the toroidal coil to circuitry on the PWB.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
93 words
An apparatus mounting a toroidal coil/core combination to a support structure having an aperture therein comprising: first engaging means adapted for insertion in the support structure's aperture securely engaging the support structure, wherein said first engaging means includes keying means for permitting said apparatus to be attached to said support structure only in a given, predetermined orientation; and second engaging means coupled to said first engaging means engaging and urging the toroidal coil/core combination in intimate contact with the support structure when said first engaging means is inserted in the support structure's aperture.
Claim 2
Independent Claim
93 words
An apparatus mounting a toroidal coil/core combination to a support structure having an aperture therein comprising: first engaging means adapted for insertion in the support structure's aperture securely engaging the support structure, wherein said first engaging means includes keying means for permitting said apparatus to be attached to said support structure only in a given, predetermined orientation; and second engaging means coupled to said first engaging means engaging and urging the toroidal coil/core combination in intimate contact with the support structure when said first engaging means is inserted in the support structure's aperture.
