Abstract
A contacting device for electrically connecting rows of tubular piezo transducers of a printing head of an ink printing device consisting of a printed circuit board having separate conductor paths, a row of feedthrough holes for each row of transducer elements with one hole for each element, a first contact element having an inside contact sleeve biased against the inside wall of the transducer element and a flexible spacer extending therefrom and through an opening in the board adjacent the feedthrough hole, a second contacting element having a resilient connector supporting a resilient clamp for embracing the outer surface of the element being mounted in another hole adjacent the feedthrough opening with both the elastic spacer and the resilient connector being soldered to the conductor paths so that the element is positioned above the feedthrough hole and an electrical current can be applied to the transducer.
