AI Technical Summary
Technical Problem
In electrical connection units where fuses are fixed to a base member, thermal expansion and contraction of the base member due to heat generation cause repeated stress on the fuse, leading to a shortened lifespan.
Method used
The electrical connection unit incorporates a base member with a space between the fixing portions for the fuse terminal portions, allowing thermal expansion and contraction to be absorbed, thereby reducing stress on the fuse.
Benefits of technology
This configuration extends the lifespan of the fuse by minimizing changes in the distance between the terminal portions, reducing thermal stress and facilitating easy assembly.

Abstract
To provide an electrical connection unit that can extend the lifespan of fuses. [Solution] An electrical connection unit according to one embodiment comprises a base member having an arrangement surface facing one side in the first direction, a fuse body, a fuse having two terminal portions provided at both ends of the fuse body and arranged on the arrangement surface, and a fixing member for fixing the terminal portions to the base member. A space is provided in the base member between the two fixing portions to which the two terminal portions are fixed.
