COIL BOBBIN FOR DRIVE COIL, AND MANUFACTURING METHOD OF THE DRIVE COIL USING THE COIL BOBBIN

摘要

PROBLEM TO BE SOLVED: To provide a bobbin of a drive coil, which makes sure the winding of the drive coil of a hammer pin drive machine element and at the same time improves the manufacturing, and to provide a manufacturing method of the drive coil using the bobbins for drive coils.;SOLUTION: In the coil bobbin for a drive coil of the drive machine element for hammer pins, a projection made of a thermoplastic material is provided at the passage of the lead-out wire at the support trunk section of the coil bobbin for retaining along the projection after the winding to the coil bobbin is completed, and the projection is heated and softened for lean on the lead-out wire, thus fixing the lead-out wire to the support trunk section of the coil bobbin.;COPYRIGHT: (C)2002,JPO
