Abstract
A transformer comprises a core formed by laminations, each having a rectangular plate with two spaced windows for receiving a set of coils passing through the windows in turn; a pair of terminal supports made of dielectric material, the supports extending through the core laminations down to the bottom thereof and being terminated by L-shaped brackets for mounting on the surface of the circuit board, the brackets spanning the width of the transformer and carrying two arrays of pins extending from the output transformer for providing connections of the coil ends with other components of the electronic device; a hexahedron mold block of thermoplastic resin with glass fiber for encapsulating the transformer leaving the pins for electrical connections.
