Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 180 words
A transformer comprising: a core having an extending member or leg; a coil winding positioned around said leg and including connecting leads, and forming a spacing between the core and the inner surface of said coil winding; an inverted L-shaped terminal support of non-conductive material having an upper body portion and a downwardly-extending leg, said downwardly-extending leg being received in friction-fit relation between said core and coil in said spacing; said body portion being sub-divided into a plurality of compartments; terminal plates conforming substantially to the size of said compartments, each of said plates including a front end having a flat section and downwardly-angled tines, said compartments having a front wall providing an upper support surface and a vertical surface, a back wall and side walls, said back wall including an overhang for engaging the back portion of said plate along its upper surface, said downwardly-angled tines being wedged and snapfittable against the vertical surface of said front wall, and said flat section engaging the upper surface of said front wall to thereby position said plates securely in respective compartments.
Claim 2
Dependent Claim 180 words
A transformer comprising: a core having an extending member or leg; a coil winding positioned around said leg and including connecting leads, and forming a spacing between the core and the inner surface of said coil winding; an inverted L-shaped terminal support of non-conductive material having an upper body portion and a downwardly-extending leg, said downwardly-extending leg being received in friction-fit relation between said core and coil in said spacing; said body portion being sub-divided into a plurality of compartments; terminal plates conforming substantially to the size of said compartments, each of said plates including a front end having a flat section and downwardly-angled tines, said compartments having a front wall providing an upper support surface and a vertical surface, a back wall and side walls, said back wall including an overhang for engaging the back portion of said plate along its upper surface, said downwardly-angled tines being wedged and snapfittable against the vertical surface of said front wall, and said flat section engaging the upper surface of said front wall to thereby position said plates securely in respective compartments.
Claim 3
Dependent Claim 29 words
An apparatus as in claim 1, wherein said compartments have a substantially rectangularly-shape; said flat section of said plates located centrally and said downwardly-angled tines straddling said flat section.
Claim 4
Dependent Claim 27 words
An apparatus as in claim 1, further including ledges on said side walls for engaging the sides of said plates along the lower surface of said plates.
Claim 5
Dependent Claim 33 words
An apparatus as in claim 1, wherein said terminal plates include an opening for receiving associated leads which may be inserted to extend outwardly to enable soldering or welding of said leads thereon.
