AI Technical Summary
Technical Problem
Conventional terminal blocks do not adequately suppress the co-rotation of bus bars, leading to potential stress concentration and instability.
Method used
A terminal block design featuring a first anti-rotation portion overlapping the fastening member in the width direction and a second anti-rotation portion spaced apart from the first in the axial direction, which distributes stress and suppresses co-rotation by supporting opposite ends of the bus bar.
Benefits of technology
The design effectively prevents localized stress concentration and co-rotation of bus bars, enhancing stability and ease of assembly.

Abstract
To provide a terminal block capable of properly suppressing bus bar corotation.SOLUTION: A terminal block 1 includes: a bus bar 10 extending along an axial direction X and connected to an external terminal 2; a housing 20 for holding the bus bar 10; and a fastening member 30 for fastening the bus bar 10 and the external terminal 2 to the housing 20 along a fastening direction Z. The housing 20 includes: a first detent part 25 supporting one end portion of the bus bar 10 in a width direction Y; and a second detent part 26 supporting another end portion of the bus bar 10 in the width direction Y. The first detent part 25 is arranged at a position overlapping the fastening member 30 in the width direction Y along the axial direction X, and the second detent part 26 is arranged at a position separated from the fastening member 30 and the first detent part 25 in the axial direction X.SELECTED DRAWING: Figure 4
