Abstract
A solenoid for an electric starter. The solenoid has a metal case that contains a coil winding assembly. The coil winding assembly includes a plastic coil spool that carries a pull-in coil and a hold-in coil. One end of the coil spool supports a plurality of axially extending metallic threaded studs that are insert molded into the end of the coil spool. The end leads of the coils are wrapped around the studs and welded thereto. The studs, together with nuts that are threaded onto the threaded portions of studs, serve to secure a plastic cover to an end of the metal case.
