Manufacturing method of transformer device
A transformer device includes: a transformer that includes a magnetic body core and a winding; a case that houses the transformer; an external terminal that is provided in the case; a relay section that is provided in the case and to which an end portion of the winding of the transformer is connected; and a conducting wire of which one end is wound around the external terminal and bonded thereto, and another end is connected to the relay section.
1. A method for manufacturing a transformer device, the method comprising:
disposing a transformer that includes a magnetic body core and a winding within a case;
winding an extending portion of the winding of the transformer around an external terminal that is provided in the case, and bonding the extending portion thereto;
severing the extending portion and detaching the extending portion from the winding of the transformer;
connecting an end portion of the extending portion on a side of the extending portion opposite to a side of the extending portion that is bonded to the external terminal to a relay section that is provided in the case; and
connecting an end portion of the winding of the transformer from which the extending portion has been detached to the relay section.
2. A method for manufacturing a transformer device, the method comprising:
disposing a transformer that includes a magnetic body core and a winding within a case which has a pillar shaped relay section:
connecting one end of a conducting wire to an external terminal provided on the case by winding the conducting wire around the external terminal:
bonding another end of the conducting wire to a top of the pillar shaped relay section; and
bonding an end portion of the winding of the transformer to the top of the pillar shaped relay section.
3. The method according to claim 2 , further comprising
covering the one end of the conductive wire wound to the external terminal with a conductive material.
4. The method according to claim 2 ,
wherein the disposing includes disposing the transformer such that the pillar shaped relay section is positioned between the external terminal and the transformer.
