Abstract
A controller includes: a circuit board; a retaining member; a bus bar that has an embedded portion embedded in and retained by the retaining member and an exposed portion that is exposed from the retaining member and that is electrically connected to the circuit board; and an electrical element that has a terminal connected to the exposed portion. The bus bar is formed in such a manner that a metal plate of which an outer surface is plated with a plating layer is cut along a predetermined cutting plane. The cutting plane at the exposed portion has a parallel portion that is arranged substantially parallel to a principal surface of the circuit board. The parallel portion and the terminal are joined to each other.
Claims8
A controller comprising:
- a circuit board;
- a retaining member;
- a bus bar that has an embedded portion embedded in and retained by the retaining member and an exposed portion that is exposed from the retaining member and that is electrically connected to the circuit board;
- and
- an electrical element that has a terminal that extends parallel to a principal surface of the circuit board and is connected to the exposed portion,
- wherein the bus bar is formed in such a manner that a metal plate of which an outer surface is plated with a plating layer is cut along a predetermined cutting plane,
- wherein the cutting plane at the exposed portion has a parallel portion that is arranged substantially parallel to the principal surface of the circuit board, and
- wherein the parallel portion and the terminal are joined to each other.
A method of manufacturing a controller that includes:
- a circuit board;
- a retaining member;
- a bus bar that has an embedded portion embedded in and retained by the retaining member and an exposed portion that is exposed from the retaining member and that is electrically connected to the circuit board;
- and an electrical element that has a terminal that extends parallel to a principal surface of the circuit board and is connected to the exposed portion,
- the method of manufacturing the controller comprising:
- producing the bus bar by cutting a metal plate of which an outer surface is plated with a plating layer along a predetermined cutting plane;
- arranging the cutting plane at the exposed portion substantially parallel to the principal surface of the circuit board;
- and
- joining the cutting plane and the terminal to each other.
