ABSTRACT:
A connector requiring minimal insertion force and forming a reliable connection has a female terminal and a male terminal. A shaft portion of the male terminal is insertable into a closed end insertion tubular portion of the female terminal. The shaft portion has an expanding slot extending along a length thereof. A projection is provided within the insertion tubular portion near the closed end. A bore diameter of the insertion tubular portion is larger than a diameter of a portion of the shaft portion that is to be first inserted. At a final stage of an insertion operation, the projection fits in the expanding slot. Accordingly, at the final stage of the insertion operation, the shaft portion is forcibly expanded radially outward and brought into contact with the bore wall of the insertion tubular portion at a predetermined contact pressure.
