ABSTRACT:
An improved transformer assembly includes a core windings about the core, and a mechanism attached to opposing ends of the core for slideably mounting the assembly to interior edges of a printed circuit board (pcb) which define a recess in the pcb. A further mechanism permits making direct electrical connection between conductors on the printed circuit board and the transformer windings. No additional fasteners or additional soldering is required. This transformer assembly is especially suited for utilization in a modem in order to reduce the thickness of its housing.
