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 dielectric bobbin threading the windows, the coils being wound over the bobbin passing through the windows in turn to form primary and secondary windings, each of the coil ends having connection pins arranged in at least two arrays, a pair of pin supports formed integral to the bobbin to span the width of the transformer and carry the arrays of connection pins, the supports extending through the core laminations down to the bottom thereof and terminating by flat bottoms resting upon the circuit board, and outwardly bent sections of the connection pins in one of the arrays to hook the circuit board at its thru holes making instantly a secure provisional joint with the trace of the circuit board.
