Abstract

An electrical junction box includes: a circuit board on which an electronic component having a main body is mounted on a mounting surface; a frame inside of which the circuit board is accommodated; a cover portion covering the circuit board from the mounting surface side; and a heat transfer member disposed between the main body and the cover portion, and the frame includes a heat transfer member holding portion holding the heat transfer member at a position where the heat transfer member is in heat conductive contact with both the main body and the cover portion.

Description

technical field [0001] The technology disclosed in this specification relates to an electrical junction box. Background technique [0002] Conventionally, an electrical junction box configured by accommodating a circuit board mounted with various electronic components in a housing is known as a device for performing energization or deenergization of, for example, an in-vehicle electrical component. [0003] In such a device, among the electronic components mounted on the circuit board, there are components that generate relatively large amounts of heat, and the inside of the housing may become high in temperature due to the heat generated from such electronic components. If the inside of the case becomes high temperature, the performance of electronic components may decrease. [0004] Therefore, various structures for dissipating heat generated from circuit boards or electronic components have been proposed conventionally. For example, Patent Document 1 discloses a structu...
