Claims

[Claims for Utility Model Registration] (1) In a bobbin for a magnetic head that is inserted into the yoke of the core and stored in a case together with the core, the yoke of the core is inserted into the inner periphery and the winding is formed on the outer periphery. A cylindrical portion to be wound, a flange integrally formed on both ends of the cylindrical portion, and a flange integrally formed on one of the flange portions, protruding toward the outer circumferential side of the cylindrical portion, and having a connector pin. a base portion, the connector portion having a lower end surface continuous with the lower end surface of the collar portion, and a flat upper end surface;
It has a plate-shaped receiving part that is integrally formed with the base and protrudes upward almost perpendicularly from the upper end surface of the base on the inner circumferential side of the cylindrical part of the base, and the two connector pins are bent to form the base. One end of the connector pin is made to protrude almost perpendicularly to the upper end surface of the base to serve as a pin terminal, and the other end of the connector pin is made to protrude from the outer peripheral side of the base to serve as a winding connection part. A bobbin for a magnetic head, characterized in that a rib is formed on the receiving part, facing the pin terminal and substantially perpendicular to the pin terminal. (2) Utility model registration claim No. 1 in which the receiving portion protrudes upward almost perpendicularly from the inner peripheral side of the base.
A bobbin for a magnetic head as described in . (3) The bobbin for a magnetic head according to claim 1, wherein the receiving portion projects upward almost perpendicularly with a gap from the circumferential side surface of the base. (4) The bobbin for a magnetic head according to any one of claims 1 to 3, wherein a groove is formed in the pin terminal side connecting portion between the receiving portion and the upper end surface of the base.
