Solenoid coil assembly and method for winding coil

摘要

A coil assembly (10) includes a spool (12) and a connector (14) keyed thereto. To wind a coil (50) on the spool (12), the spool (12) is moved linearly with respect to the connector (14) until the connector (14) does not interfere with the winding bay (22) on the spool (12). Thereafter, a wire (48) is wound around the spool (12) within the winding bay (22) to form the coil (50). Once the coil (50) is complete, the spool (12) can be moved linearly with respect to the connector (14) until a keying structure on the spool (12) engages an opposing keying structure on the connector (14) and a locking mechanism on the spool (12) engages a corresponding locking mechanism on the connector (14). Thus, a complete coil assembly (10) can be manufactured in one operation with minimal manufacturing steps.
