Abstract

The present disclosure enables a cost reduction for a circuit assembly including electronic components. A circuit assembly includes: an electronic component; a conductive plate to which the electronic component is connected; and a holding member that holds the conductive plate. The conductive plate includes a mounting portion on which the electronic component is mounted, and a fiducial mark for positioning and mounting the electronic component. The fiducial mark is constituted by a hole formed in the conductive plate.

First claim

What is claimed is:

1. A circuit assembly comprising:
an electronic component;
a conductive plate to which the electronic component is connected; and
a holding member that holds the conductive plate,
wherein the conductive plate includes a mounting portion on which the electronic component is mounted, and a fiducial mark for positioning and mounting the electronic component, and
the fiducial mark is constituted by a hole formed in the conductive plate; and wherein the holding member includes a base portion that is plate-shaped and is provided along the conductive plate, and the base portion includes an opening that exposes a region that includes the hole and an area surrounding the hole.

2. The circuit assembly according to claim 1 , wherein the holding member is made of a resin, and
the conductive plate and the holding member are formed as one piece with the conductive plate partially buried in the holding member.

3. The circuit assembly according to claim 2 , wherein a plurality of conductive plates are held by the holding member, and
each of the conductive plates is provided with a hole.

4. The circuit assembly according to claim 2 , wherein the conductive plate is provided with a plurality of holes.

5. The circuit assembly according to claim 1 , wherein a plurality of holes serve as fiducial marks and are provided while being distanced from each other.

6. The circuit assembly according to claim 5 , wherein a plurality of conductive plates are held by the holding member, and
a first conductive plate has one of the holes serving as the fiducial marks, and
a second conductive plate has another hole serving as the fiducial mark.

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