Abstract
Abstract Electrical inductive apparatus having a static plate which includes a flat, electrically conductive sheet member disposed between first and second sheets of electrical insulating material, and electrically conductive edge strips disposed about the inner and outer edges thereof. The electrically conductive edge strips are formed of metallic wire cloth disposed to provide a single turn about a flexible insulating core. The metallic wire cloth is sized to provide at least one flap which extends outwardly from the insulating core, with the flap being of sufficient length to overlap the adjacent edge of the electrically conductive sheet member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
Electrical inductive apparatus comprising: a magnetic core, a plurality of pancake coils disposed in inductive relation with said magnetic core, said plurality of pancake coils being electrically connected to provide at least one winding, and at least one static plate disposed adjacent a predetermined pancake coil, said static plate including an electrically conductive member having first and second major opposed sides, Means electrically insulating said electrically conductive member, and edge strip means disposed about the edges of said static plate for shielding the edges of said electrically conductive member, said edge strip means including a core member formed of an electrically insulating material, an electrically conductive member formed of metallic wire cloth which is folded about said core member, said metallic wire cloth having a width dimension sufficient to provide first and second outwardly extending flaps, said flaps overlapping and electrically contacting said first and second major opposed sides, respectively, of said electrically conductive member.
