A production method for a contact mat for electrical contacting of an actuator uses a contact mat roll including (a) a plurality of terminal posts spaced apart from each other and extending in a first direction and (b) a plurality of electrically-conductive wires extending parallel to each other in a second, perpendicular direction, such that each wire extends across the terminal posts. The method includes unwinding the contact mat roll; connecting the wires to a metallization strip of an actuator; separating the wires at a location between adjacent terminal posts in the mat, such that a contact mat, including a single terminal post and the wires extending from the metallization strip to the terminal post, is connected to the actuator; and winding a free end of the contact mat including the terminal post at least partially around the actuator and securing the terminal post in position.

Production method of contact mat for an actuator

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 () and a second () bush elements which are interconnected when the bush is mounted. The first element () is provided with through holes () for the connection pins of the inventive piezoelectric actuator. The second element () is provided with at least one guide () for the connection pins.

Reception bush for a piezoactuator

A contact mat () for electrically contacting an actuator, particularly a piezo actuator for an injector of an injection system has several electrically conductive wires () that are placed next to each other and several mechanical transversal connections located between the individual wires (). The transversal connections consist of one respective terminal post (-) of the actuator.

Contact mat for an actuator, and associated production method

The invention relates to a receiving sleeve for a piezoelectric actuator, in particular for a piezoelectric actuator for driving an injector of an injection system in an internal combustion engine. Said sleeve comprises a first sleeve part () and a second sleeve part (), the first sleeve part () being connected to the second sleeve part () when the sleeve is assembled. In addition, the inventive receiving sleeve comprises an anti-rotation element () for maintaining a predefined angular position between the first sleeve part () and the second sleeve part ().
