Abstract: A bridging terminal includes a cap and four conductive pieces. Each of the flexible conductive pieces has two pin portions and a connecting portion. The connecting portions are combined in an assembling chamber of the cap. The pin portion of the first flexible conductive piece has a front-left-outer facet and a front-right-outer facet jutting frontward, and has a flexible arch jutting backward. The second and third flexible conductive pieces have each of their pin portions including a left-outer facet, a right-outer facet and a slot. The pin portion of the fourth flexible conductive piece has a rear-left-outer facet and a rear-right-outer facet jutting backward, and has a flexible arch jutting frontward. When the flexible conductive pieces are aligned and piled, the flexible arches are received in the corresponding slots. Thereby, the bridging terminal provides improved electric conductivity, bonding strength and stability, while preventing elastic fatigue and premature failure.
