Patent ID: 7952024

Claim:
A U-turn bus bar comprising: a body portion constituting a linear essential part formed of a conductive plate member, having an overall thickness (t) and an overall width ( 2 b ); at least a terminal portion expanded in the direction perpendicular to the longitudinal direction of the body portion; and a connection hole formed at one end of the body portion; wherein the body portion includes the U-turn bend formed by bending, in the U-turn shape, a single wire member of a conductive material having the width (b) of one half of the overall width ( 2 b ) and the same thickness (t) as the overall thickness, wherein the wire member is divided into a first wire member on one side and a second wire member on the other side at the U-turn bend, wherein the body portion also includes a parallel portion having the first wire member and the second wire member coupled to each other, the parallel portion being fixed by a spot, wherein the second wire member of the body portion of the bus bar is formed with at least a protrusion for a terminal, being bent and projected in such a manner so as to be spaced from the first wire member, and wherein the U-turn bend has a connection hole formed by coupling the first wire member and the second wire member in annular shape.
