Solenoid coil assembly and method for winding coils

摘要

A coil assembly includes a spool and a connector keyed thereto. To wind a coil on the spool, the spool is moved linearly with respect to the connector until the connector does not interfere with the winding bay on the spool. Thereafter, a wire is wound around the spool within the winding bay to form the coil. Once the coil is complete, the spool can be moved linearly with respect to the connector until a keying structure on the spool engages an opposing keying structure on the connector and a locking mechanism on the spool engages a corresponding locking mechanism on the connector. Thus, a complete coil assembly can be manufactured in one operation with minimal manufacturing steps.
