Metal core board for vehicle-mountable junction box

摘要

Provided is a metal core board which has a preferable function for a vehicle-mountable junction box, specifically, is reduced in size or improved in mounting efficiency. A metal core board for a vehicle-mountable junction box, which is mountable on the vehicle-mountable junction box, wherein a core plate forming an intermediate layer of the metal core board has a plurality of slits and an island surrounded by separating connection parts present between the slits; and in the state where the island is held between insulating layers stacked on both of two surfaces of the core plate, through-bores 46 are formed at the separating connection parts to remove the separating connection parts and the island is made electrically independent from a remaining part of the core plate while being held between the insulating layers. Thus, a plurality of circuits can be formed.

1. A metal core board for a vehicle-mountable junction box, which is mountable on the vehicle-mountable junction box, comprising:
a core plate forming an intermediate layer of the metal core board comprising an island, a plurality of slits that surround an entirety of the island, and separating connection parts present between the slits; wherein the core plate is a first thickness; wherein the separating connection parts are a second thickness; wherein the plurality of slits are a third thickness that is more than twice the first thickness; wherein the second thickness and the third thickness are substantially the same; wherein the plurality of slits have shapes of bent and/or straight thready-lines; and wherein, in the state where the island is held between insulating layers stacked on both of two surfaces of the core plate, the separating connection parts are removed and the island is made electrically independent from a remaining part of the core plate while being held between the insulating layers.
