LOW RELUCTANCE INDUCTOR
First Claim
1. An inductive device comprising a brittle, sintered cylindrical core, a winding thereon, and a brittle, sintered shell having side wall, end walls and a cavity therewithin containing said core and enclosing said winding, said shell being longitudinally divided on a plane containing the axis of said core and having arcuate notches in the free edges of the end walls thereof conforming to and encompassing the cylindrical ends of said core, said notches being less than semicircular so that the facing edges of said shell parts are spaced narrowly apart when said core is contained in said notches, adhesive means spanning said facing edges of said shell parts to secure said shell parts together and in direct contact with said cylindrical ends of said core, said device being characterized by the absence of adhesive between said core and said notches.
