Abstract
A transformer (1) for a printed circuit board (2) is provided with physically separate flat metal windings (6) which are chosen to take the highest or the two highest currents handled by the transformer (1). The lower currents which will often include the power input to the primary are printed on the surfaces (3,4) of the printed circuit board (2). The flat metal windings (5) may be pre-assembled with the core halves (6,7).
Claims19
A transformer comprising:
- a printed circuit board;
- a main low current winding comprising a printed winding for the transformer formed on the circuit board;
- a high current winding comprising a physically separate winding formed from a flat metal sheet and integral terminals formed by portion of the sheet;
- a core mounting means formed by core receiving through holes in the printed circuit board;
- a core formed from upper and lower core halves having portions extending respectively through the core receiving through holes and mounting the separate winding in register with the printed winding and in close contact therewith;
- means for connecting the core halves;
- and
- the printed winding incorporates an auxiliary winding for modified voltage output for other parts of a circuit of the printed circuit board.

A transformer comprising:
- a multi-layer printed circuit board;
- a main low current winding comprising a printed winding for the transformer formed on the circuit board;
- at least one auxiliary winding incorporated in the printed winding for modified voltage output for other parts of a circuit of the printed circuit board;
- a high current winding comprising a physically separate winding formed a flat metal sheet and integral terminals formed by portion of the sheet;
- a core mounting means formed by core receiving through holes in the printed circuit board;
- a core formed from upper and lower core halves having portions extending respectively through the core receiving through holes and mounting the separate winding in register with the printed winding and in close contact therewith;
- and
- means for connecting the core halves.
5 more elements
A transformer comprising:
- a multi-layer printed circuit board;
- a plurality of main low current windings printed on different layers of the printed circuit board;
- at least one auxiliary low current winding printed on one of the layers of the printed circuit board said auxiliary low current winding having a current output different to that of the main low current windings for modified voltage output for other parts of the printed circuit board;
- a core formed from upper and lower core halves having portions extending respectively through the core receiving through holes and mounting a separate winding in register with at least one main low current printed winding and in close contact therewith;
- and
- means for connecting the core halves.
