Abstract
A connecting terminal developed speedily while limiting a temperature rise when a current flows, comprising male and female terminals each having a wire crimp portion to which a wire is crimped, and a joint portion where the male and female terminals are joined to each other, wherein a contact resistance value of the whole connecting terminal is a sum of contact resistance values in the wire crimp portions and the joint portion, and a length of a contact portion is a sum of lengths of the wire crimp portions and the joint portion, wherein a normalized contact resistance value Rter is derived by dividing the contact resistance value by the length, and a relationship of a wire resistance value Rwire of the wire, a current value I and a permissive increase in temperature ΔT to the normalized contact resistance value Rter is expressed by Rter<ΔT/(752×I2)−3.7×Rwire.
