Abstract

An electrical junction box for distributing electric power in a vehicle includes: a metal core substrate 1 provided with a core metal assembly having two core metal plates arranged with a gap, and an insulating layer embedded in the gap and covering surfaces of the metal core plates to integrate the metal core plates; and electronic components. Electric power from a battery is inputted into the core metal plate, and electric power from an alternator is inputted into the core metal plate. The electronic components are provided with a plurality of attaching portions soldered or screwed to the metal core substrate. At least one of the attaching portions is attached to the core metal plate, and at least one of the attaching portions is attached to the core metal plate.

Claims

1. An electrical junction box for respectively distributing inputted electric power from power sources of a plurality of systems to a plurality of metal core plates comprising:

a metal core substrate provided with a core metal assembly having the core metal plates arranged with slit-shaped gaps, and an insulating layer embedded in the gaps and covering surfaces of the metal core plates to integrate the metal core plates; and

electronic components mounted on the metal core substrate,

wherein the electronic components are provided with a plurality of attaching portions soldered or screwed to the metal core substrate, and

wherein at least one of the attaching portions is soldered or screwed to one of the cone metal plates adjacent to each other with the gap therebetween, and at least one of the attaching portions is soldered or screwed to the other one of the core metal plates adjacent to each other with the gap therebetween.

2. The electrical junction box as claimed in claim 1,

wherein the core metal assembly is formed in a rectangular shape, and

wherein the gap at least includes:

a first straight portion extended straight from one side of the rectangular shape; and

a second straight portion extended from the other side of the rectangular shape, parallel to a virtual extension line of the first straight portion, and not arranged in alignment with the first straight portion.

3. The electrical junction box as claimed in claim 1,

wherein one of the core metal plates adjacent to each other with the gap therebetween is provided with a convex projected toward the other core metal plate, and the other core metal plate is provided with a concave where the convex is positioned.

4. The electrical junction box as claimed in claim 2,

wherein one of the core metal plates adjacent to each other with the gap therebetween is provided with a convex projected toward the other core metal plate, and the other core metal plate is provided with a concave where the convex is positioned.
