Claims

[Scope of utility model registration request]

An outer bobbin is provided with a flange having a hole for passing the external lead wire at one end of the winding drum, and an outer lead is provided at the opposite end of the inner winding drum that is inserted into the winding drum of the outer bobbin. It consists of an inner bobbin provided with a flange having a hole for wire insertion, and this inner bobbin has a discontinuous section on the outer peripheral surface of the winding drum that separates the coil-wound part at the center and the non-wound parts at both ends. A protrusion is formed, and this protrusion is brought into close contact with the winding drum of the outer bobbin, and the flange of the inner bobbin engages with the outer bobbin winding.
In addition to providing a groove for air ventilation at the end of the body,
A coil bobbin characterized in that a concave groove is provided at the end of the outer bobbin opposite to the winding drum for allowing a filler to penetrate into the winding drum.
