Abstract

A reception bush for a piezoelectric actuator is provided with two connection pins for electrically bonding the piezoelectric actuator, in particular for a piezoelectric actuator controlling the injector of an injection system for an internal combustion engine. The reception bush has a first (1) and a second (2) bush elements which are interconnected when the bush is mounted. The first element (1) is provided with through holes (4, 5) for the connection pins of the inventive piezoelectric actuator. The second element (2) is provided with at least one guide (12) for the connection pins.
