Contact device manufacturing method for piezo actuator of leakingless common rail injector, involves providing parallel contact guides, where one guide has contact pin for electrically contacting external electrode and contact plate

摘要

The method involves providing two parallel contact guides, where one of the contact guides has a contact pin for electrical contacting of an external electrode of a piezo actuator and a contact plate for electrical contacting with a supply potential. The contact guides are injection molded with a plastic and arranged in a high pressure adapter through drillings. The contact guides are injection molded with another plastic for the formation of a plug, which is coupled with a supply potential connection device. An independent claim is also included for a contact device for electrical contact of a piezo actuator of an injector.
