Abstract

A busbar unit includes a busbar connected by welding to a connection terminal of a ceramic capacitor and a molding part formed of the molding resin to cover the busbar, the busbar includes a body part covered by the molding part and a terminal part projecting from the molding part and connected to the connection terminal of the ceramic capacitor, and the molding part is formed with a guide hole to guide the connection terminal of the ceramic capacitor to bring the connection terminal into contact with or into proximity to the terminal part.

First claim

1 . A busbar unit, comprising:
a busbar connected by welding to a connection terminal of an electronic component; and a molding part formed of molding resin to cover the busbar; wherein the busbar includes:
a body part covered by the molding part; and
a terminal part projecting from the molding part and connected to the connection terminal of the electronic component; and
the molding part is formed with a guide hole to guide the connection terminal of the electronic component to bring the connection terminal into contact with or into proximity to the terminal part.

2 . The busbar unit according to claim 1 , wherein:
a part of an inner peripheral surface of the guide hole is formed to be continuous with a side surface of the terminal part connected to the connection terminal of the electronic component.

3 . The busbar unit according to claim 2 , wherein:
the inner peripheral surface of the guide hole has a D-shaped cross-sectional shape having a flat surface part and a curved surface part; and the flat surface part is formed to be continuous with the side surface.

4 . The busbar unit according to claim 1 , wherein the guide hole includes:
a guide part into which the connection terminal of the electronic component is inserted to guide the connection terminal of the electronic component to bring the connection terminal into contact with or into proximity to the terminal part; and a tapered part open in a tapered manner on a surface of the molding part on a side where a body part of the electronic component is provided.

5 . An electronic device, comprising:
the busbar unit according to claim 1 ; and the electronic component; wherein: the connection terminal of the electronic component includes a bent part formed by being bent; and a part of the connection terminal of the electronic component closer to a tip than the bent part is inserted into the guide hole.
