Abstract

A pluggable print head for an electroerosion printer can be fabricated by forming a pair of planar multielectrode devices, mounting the devices on opposite sides of a supporting insulator, and severing the ends of the devices into separate electrodes.

Multielement Print Head

A pluggable print head for an electroerosion printer can be fabricated by forming a pair of planar multielectrode devices, mounting the devices on opposite sides of a supporting insulator, and severing the ends of the devices into separate electrodes.

Referring to Fig. 1, a six-electrode device 1 is formed by stamping or etching to have substantially parallel electrodes 2 joined at writing ends 3 and connection ends 4. A second device (not shown), having five electrodes, is formed by the same technique. These two devices are vertically displaced with respect to each other so that the ends of the electrodes are intermeshed and then cemented to opposite sides of insulator sheet 5, as seen in Fig. 2. The exposed writing ends of the electrodes 2 and insulator sheet 5 can be coated with glass 8 to provide a wear surface. Electrode ends 3 and 4 are thereafter cut off, leaving two layers of individual electrodes. The assembled electrodes and insulator plate are then encapsulated with support guides 6 in a suitable mold to form a pluggable head
7.
