Abstract

PURPOSE:To prevent the deformation of sheet cores by a method wherein when a plurality of sheet cores of two kinds consisting of long E-shaped core sheets and short E-shaped core sheets which differ individually in a protruded length is laminated alternately and inserted into a winding bobbin, the surface of the core is coated preliminarily with themosetting resin and insertion after adhesion- fixing is performed. CONSTITUTION:A protruded segments 1a-1c of a long E-shaped sheet core 1 is built to be longer, and a protruded segments 2a-2c of a short E-shaped sheet core 2 is built to be shorter than the protruded segments 1a-1c. Next these cores 1 and 2 are laminated alternately, and by protruded segments 1b and 2b which are faced with each other in two E-shaped cores of laminated elements butted through insertion into a winding bobbin, a coil with magnetic core is completed. In this constitution after thermosetting resin is applied all over the surface before a laminated elements are completed, that is when they are still thin plates of a permalloy or a silicon steel, they are punched out by press, and after these punched core are laminated, they are fixed mutually by heating.
