Piezoelectric printing head for ink jet printer, and method

摘要

A printing head for an ink jet printer has a plurality of ink channels formed as hollow tubes, each with a hollow cylindrical piezoelectric transducer, which tubes are interconnected to form a piezoelectric tube group. The piezoelectric tube group is assembled with a front housing part which supports the front end of the tube group, and a housing cap bearing electrical contacts engaging the piezoelectric tube elements is assembled in place, after which the interior is filled with a casting resin.
