AI Technical Summary

Technical Problem

Existing electrical connection units face challenges in improving thermal characteristics, particularly in managing heat generation and thermal interference from electronic components and wiring materials.

Method used

The electrical connection unit incorporates a first wiring material with a connection portion and a first heat storage member, where the thickness of the heat storage member in a specific direction is at least twice that of the connection portion, and is clamped together with the wiring material, enhancing heat storage capacity and reducing thermal interference.

Benefits of technology

This configuration effectively suppresses large temperature rises and thermal interference, improving the thermal characteristics of the electrical connection unit by efficiently managing heat generated from connection points.

Abstract

This electrical connection unit (1) comprises a first wiring material (30A) and a first heat storage member (50A). The first wiring material (30A) includes a connection part (31) that has a first attachment hole (31h) and is fixed to a first connection target (10) by a first fastening member (41A) inserted into the first attachment hole (31h). The first heat storage member (50A) has a second attachment hole (50h) facing the first attachment hole (31h) and is fastened together with the first wiring material (30A) due to the first fastening member (41A) being inserted into the second attachment hole (50h). When the direction in which the first connection target (10) and the connection part (31) overlap is defined as a first direction, the thickness (T50) of the first heat storage member (50A) in the first direction is twice or more the thickness of the connection part (31) in the first direction.
