Method for mounting a contact pin for a piezoelectric element, sleeve, and actuator unit

摘要: During the production of an actuator unit (11), which should be installed in a fuel injector, piezoelectric element (8) is firstly inserted into plastic sleeve (1). Two contact pins (5) are provided for external power supply (8), and guided outside In order to fix position (5), particularly before encapsulating with (1), pin mounts (2) form detent connections (5). The designed fixing thereof after they have been these connections. one particular embodiment, (1) one-piece hollow body so that mounting can effected simple manner.
