Abstract

A circuit assembly includes a substrate having a conductive path, electronic components mounted on the substrate, and a terminal block that is in contact with the substrate, in which the terminal block includes a terminal portion that is connectable to a counterpart terminal, a terminal holding portion for holding the terminal portion, and support portions for supporting the terminal holding portion, and the electronic components are disposed between the terminal holding portion and the substrate.

First claim

The invention claimed is:

1. A circuit assembly comprising:
a substrate having a conductive path;
an electronic component mounted on the substrate;
an extension portion that is continuous with the terminal portion and extends along a surface of the substrate, wherein the extension portion is enveloped by a magnetic core;
an extension holding portion for holding the extension portion,
the extension holding portion extends from at least one of the terminal holding portion and the support portion;
a terminal block that is in direct contact with the substrate;
wherein the terminal block includes a terminal portion that is connected to a counterpart terminal,
a terminal holding portion for holding the terminal portion,
and a support portion for supporting the terminal holding portion;
the electronic component is disposed between the terminal holding portion and the substrate; and
the extension holding portion has a fitting portion that is cut out such that the magnetic core is fitted around the fitting portion.

2. The circuit assembly according to claim 1 , wherein a detection portion for detecting a voltage of the terminal portion is branched from the extension portion, and the detection portion is connected to a conductive path of the substrate.

3. The circuit assembly according to claim 2 , wherein the terminal portion is an output terminal for outputting power to the counterpart terminal.

4. The circuit assembly according to claim 1 ,
wherein an extension holding portion for holding the extension portion extends from at least one of the terminal holding portion and the support portion, and
the extension holding portion has a fitting portion that is cut out such that the magnetic core is fitted around the fitting portion.

5. The circuit assembly according to claim 1 , wherein the terminal portion is an output terminal for outputting power to the counterpart terminal.

6. An electrical junction box comprising:
the circuit assembly according to claim 1 ; and
a case for housing the circuit assembly.

7. The electrical junction box according to claim 6 , wherein a detection portion for detecting a voltage of the terminal portion is branched from the extension portion, and the detection portion is connected to a conductive path of the substrate.
