Abstract

An objective of the present invention is to provide a terminal connecting structure which may enable the conductivity to be improved. A terminal connecting structure is intended for connecting a terminal to an electric wire, the electric wire including an aluminum conductor with aluminum, wherein the terminal connecting structure further comprises a conductive connection body formed with aluminum, wherein one end of the connection body is butt-connected to the aluminum conductor, and wherein another end of the connection body is connected to the terminal via crimping. This enables the terminal to be connected to the electric wire via the connection body without crimping the bundle of cores. This may eliminate influence of crimping on the aluminum conductor and enable the conductivity between the electric wire and the terminal to be improved.

First claim

wherein one end of the connection body is butt-connected to the aluminum conductor, and
wherein another end of the connection body is connected to the pair of connection body crimped elements via crimping and only the connection body is crimped.

2. The terminal connecting structure according to claim 1 ,
wherein the terminal includes a partner connecting section, and
wherein the partner connecting section has a bolt hole and is formed in a plate-shape.

3. The terminal connecting structure according to claim 1 ,
wherein the aluminum conductor is formed from a bundle of the multiple aluminum strands,
wherein the connection body comprises an intersection face intersecting an axis of the electric wire, and
wherein it is configured so that each of the tip end faces of the multiple aluminum strands comes into contact with the intersection face to electrically connect the aluminum conductor to the connection body.

4. The terminal connecting structure according to claim 2 ,
wherein the aluminum conductor is formed from a bundle of multiple aluminum strands,
wherein the connection body comprises an intersection face intersecting an axis of the electric wire, and
