REACTOR AND MANUFACTURING METHOD OF THE SAME
First Claim
1. A manufacturing method of a reactor, comprising:
- assembling an assembly constituted by a coil and a bobbin which bobbin includes a tube portion and a flange portion, by inserting the bobbin, through the coil so that a tip of the tube portion protrudes from the coil;
forming a cavity by installing the assembly in a first die so that a portion of a coil lateral face comes into contact with a cavity face of the first die, and closing a second die so that the second die is opposed to the first die; and
inserting first press rods into the cavity to reach the bobbin through a cavity face of the second die, and injecting a resin into the cavity while pressing, from an opposite side of the tube portion from the portion of the coil lateral face, both ends of the bobbin in an axial direction of the coil with the first press rods.

7. A reactor comprising:
-
a bobbin that is constituted by at least a bobbin body and a flange part; a coil that is constituted by a rectangular wire wound edgewise outside the bobbin; and a core that passes inside the bobbin, wherein the bobbin body is constituted by a tube portion, a flange portion that is fixed to a first end of the tube portion, and a plate portion that extends from a second end of the tube portion in an axial direction of the tube portion, the flange part is mounted to the second end of the tube portion, and a coil lateral face includes a portion that is exposed from a resinous cover, and a portion that is covered with the resinous cover. - View Dependent Claims (8, 9)
