Transformer device and manufacturing method thereof
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 transformer device comprising:
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,
wherein the conducting wire is formed by an extending portion of the winding of the transformer, and
the extending portion is severed at the end portion of the winding of the transformer and detached from the winding of the transformer.
2. The transformer device according to claim 1 , wherein
the relay section is formed by an electrically conductive adhesive or a brazing material.
3. The transformer device according to claim 1 , wherein
the relay section is formed by an electrically conductive adhesive.
4. The transformer device according to claim 1 , wherein
the relay section is formed by an electrically conductive adhesive that fills a recessing section formed in the case.
5. The transformer device according to claim 1 , wherein
the one end of the conducting wire is bonded to the external terminal by an electrically conductive adhesive or a brazing material.
