Integrated solenoid circuit assembly

摘要

An improved method is provided for mounting a header to an insulator body of an automatic transmission solenoid assembly. The insulator body is provided with an overmolded lead frame. The insulator body and lead frame each include a plurality of terminal pin receiving holes for receiving respective terminal pins of a header therein. The terminal pins are fountain soldered to the lead frame in order to provide a connection between the terminal pins and the lead frame. The header is also provided with a pair of header posts which extend through corresponding holes in the insulator body. Weld nuts are ultrasonically welded to the header posts in order to secure the header to the insulator body.
