Abstract

Provided is a circuit assembly that does not need to include test circuit components that are mounted on a control board in a one-to-one relationship with electronic components. A circuit assembly includes a plurality of electronic components; a plurality of control terminals electrically connected to the plurality of electronic components; a holding member that has insulating properties and holds the plurality of control terminals; and a control board configured to output signals to the electronic components via the control terminals, wherein each of the control terminals includes: a first terminal body portion connected to the control board: a pad portion that is electrically connected to the first terminal body portion, is provided along the holding member, and is exposed from part of the holding member; and a second terminal body portion electrically connected to the pad portion and the corresponding electronic component.

First claim

What is claimed is:

1 . A circuit assembly comprising:
a plurality of electronic components; a plurality of control terminals electrically connected to the plurality of electronic components; a holding member that has insulating properties and holds the plurality of control terminals; and a control board configured to output signals to the electronic components via the control terminals, wherein each of the control terminals includes:
a first terminal body portion connected to the control board;
a pad portion that is orthogonal to the first terminal body portion and is electrically connected to the first terminal body portion, is provided along the holding member, wherein the pad portion has a bottom surface that is embedded in the holding member and a top surface opposite of the bottom surface that is exposed from part of the holding member; and
a second terminal body portion electrically connected to the pad portion and the corresponding electronic component.

2 . The circuit assembly according to claim 1 , wherein the first terminal body portion includes: a first face exposed from the holding member; and a second face that is located opposite to the first face and is exposed from the holding member, and
the pad portion includes: an exposed face exposed from the holding member; and a contact face that is located opposite to the exposed face and is in contact with the holding member.

3 . The circuit assembly according to claim 1 , wherein the first terminal body portion, the pad portion, and the second terminal body portion are made of a single metal member.

4 . The circuit assembly according to claim 1 , wherein the pad portion extends from a base portion of the first terminal body portion, and
the holding member includes an embedding portion in which a boundary region between the first terminal body portion and the pad portion of the control terminal is embedded.

5 . The circuit assembly according to claim 1 , wherein the exposed face of the pad portion has an elongated shape.

6 . The circuit assembly according to claim 1 , wherein the second terminal body portion includes: a terminal face that is exposed from the holding member and is connected to the corresponding electronic component; and a second exposed face that is located opposite to the terminal face and is exposed from the holding member.

7 . An electrical junction box comprising:
the circuit assembly according to claim 1 ; and a cover that covers the circuit assembly.
