PROBLEM TO BE SOLVED: To provide a connection terminals of fitting type which can reduce the inserting force of terminals with stable contact resistance maintained. SOLUTION: Tinning thickness of one of a male terminal 10 or a female terminal 20 is set for 0.1μm to 0.3μm, and the other tinning thickness is set for 0.1μm or above. As the tinning gets thinner, hardness of copper or a copper alloy begins to affect hardness of the terminals, then apparent hardness of the terminals gets higher. Consequently cohesion of the tinning is inhibited, and the terminal inserting force can be reduced by at least 10% or above compared with the benchmark (10μm in both of male and female terminals). The inserting force can be reduced by 30% or above, particularly when thickness of the male terminal 10 is set for 0.1μm, and thickness of the female terminal 20 is set for 0.3μm to 1.0μm. |
