Abstract
Abstract A reactor coil form or bobbin comprising shelves for holding magnetic laminations in place and structured to additionally space the reactor from a potting container. The shelves include irregularities to produce better bonding of the potting compound to the shelves and the magnetic laminations. Further, the coil form includes integral stand-off and mounting projections for positioning and holding a potted reactor to and slightly off a mounting base.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
215 words
Integral reactor coil form means for use with an electrical winding means and magnetic core means comprising, in combination: a rectangular conduit means including first, second, third, and fourth sides each having first and second ends and each having interior and exterior portions; flanges perpendicular to said first and third sides at said first and second ends thereof; and shelves extending outwardly from said conduit means parallel to said second and fourth sides at the first and second ends of each of said second and fourth sides, said shelves further extending outwardly at the ends thereof in a direction parallel with the axis of the conduit means further than at the more centrally located portions of said shelves, said shelves being further structured to include spherical contact means on the interior portion thereof for providing contact with inserted magnetic core means and said shelves being further structured so that the more centrally located edges thereof slope inward from the exterior portion to the interior portion, whereby magnetic core means inserted into the interior portion of said coil form are held in place by said spherical contact means of said shelf means and wherein said flange means prevents contact of the magnetic core means with electrical winding means on the exterior portion of said conduit means.
Claim 2
Dependent Claim
215 words
Integral reactor coil form means for use with an electrical winding means and magnetic core means comprising, in combination: a rectangular conduit means including first, second, third, and fourth sides each having first and second ends and each having interior and exterior portions; flanges perpendicular to said first and third sides at said first and second ends thereof; and shelves extending outwardly from said conduit means parallel to said second and fourth sides at the first and second ends of each of said second and fourth sides, said shelves further extending outwardly at the ends thereof in a direction parallel with the axis of the conduit means further than at the more centrally located portions of said shelves, said shelves being further structured to include spherical contact means on the interior portion thereof for providing contact with inserted magnetic core means and said shelves being further structured so that the more centrally located edges thereof slope inward from the exterior portion to the interior portion, whereby magnetic core means inserted into the interior portion of said coil form are held in place by said spherical contact means of said shelf means and wherein said flange means prevents contact of the magnetic core means with electrical winding means on the exterior portion of said conduit means.
Claim 3
Dependent Claim
33 words
Apparatus as claimed in claim 1 wherein said shelves additionally comprise internally threaded mounting posts on the shelves attached to said second side, said posts being perpendicular to the plane of said shelves.
Claim 4
Dependent Claim
86 words
A reactor means including the apparatus of claim 1 and comprising in addition for receiving electrical terminal means; winding means wound on said conduit means; and magnetic core means inserted in said conduit means and between said shelves whereby said spherical contact means of said shelves hold said magnetic means in place and said shelves extend in all directions beyond said magnetic means for protection of said magnetic means for environmental contacts and wherein said flanges protect said winding means from contact with said magnetic means.
Claim 5
Dependent Claim
33 words
Apparatus as claimed in claim 3 wherein at least one of said shelves include friction fitted terminals inserted in the cavities thereof for connection to input and output leads of said reactor winding.
Claim 6
Dependent Claim
60 words
Apparatus as claimed in claim 3 wherein said shelves include further flanges in the form of teeth to separate wires leading to said winding and to prevent spreading of the winding as it is placed on said reactor coil form and additionally including straight wire terminals inserted in the cavities of said shelf means for connection to said winding leads.
Claim 7
Dependent Claim
70 words
Hermetically sealed reactor means including the apparatus of claim 5 and comprising in addition: environmental protective container means enclosing said reactor means; hermetic sealing compound situated in said container means and substantially enclosing said reactor means; internally threaded mounting posts forming an integral part of the shelves of said form and electric terminals extending from said shelves and both said posts and said terminals protruding from said hermetic sealing compound.
Claim 8
Dependent Claim
33 words
Apparatus as claimed in claim 6 wherein said posts also extend beyond the confines of said container means anD wherein one of said posts includes orientation means for identification of the electric terminals.
