Patent ID: 7498917

Claim:
A transformer for mounting on a top surface of an electronic circuit board having multiple components and printed at its bottom surface with traces of circuit, wherein the transformer comprises a core formed from portions of ferrite core material, each portion of ferrite core material adapted and shaped for receiving coils passing around the core; a pair of terminal supports made of dielectric material extending through the core laminations and terminated by L-shaped brackets mounted on the surface of the circuit board, the brackets spanning the width of the transformer and carrying an array of pins extending from the output transformer for providing connections with the circuit board by soldering as with other components, an improvement comprising: an injected thermoplastic block for completely surrounding the transformer leaving the array of connecting pins, whereby dissipation of heat from the operating transformer is less interfered by other components but expedited through the thermoplastic block as well as the atmosphere, wherein the terminal supports of the transformer having one of its L-shaped brackets hug the circuit board at its top surface and a side wall area and fixed thereto in a cantilevered mounting with an array of the pins from the transformer making direct contact with the trace of the circuit board.
