Claims3
An electromagnet assembly for mosaic printing head comprising:
- (a) a plurality of separate electromagnets, each one formed by a separate individual core and at least a winding coupled to said core, said winding being supported by a reel provided with electrical connecting pins;
- (b) a printed circuit board to which said plurality of electromagnets is fixed by soldering of said pins to said printed circuit board, with exclusion of any other means fixing together said electromagnets;
- (c) connection means through which said printed circuit board may be connected to an external electric circuit;
- and
- (d) insulating plastic means (enclosing) steadily encapsulating as an insert said printed circuit board and said plurality of electromagnets, except said connection means, in a unitary block, said plastic means and said printed circuit board being in lieu of any other mechanical support of said plurality of electromagnets.
