Abstract: An electrical connector structure with high performance to support a new generation hardware structure for high-frequency signal transmission is illustrated. In one of the terminal slots of an upper row and a lower row, there are paired differential signal terminals and two ground terminals, by making the paired differential signal terminals not completely isolated to each other and making the two ground terminals adjacent to the paired differential signal terminals not completely isolated to the differential signal terminals respectively, the two differential signal terminals can efficiently transmit the high-frequency signals at a high speed. Moreover, by disposing the rib on the wall surface and by effectively widening the widths of the conductive terminals and shortening the lengths of the conductive terminals, the impendences which the conductive terminals are exposed to the air can be reduced.

Abstract: A grounding sheet having a body and elastic conduction sheets is provided. The elastic conduction sheet has a first elastic sheet and a second elastic sheet, each of the first elastic sheet and the second elastic sheet a closed terminal, a floating arm, a connection arm, at least one free terminal and at least one end terminal, wherein the closed terminal is connected to the body of the grounding sheet, the connection arm is connected to the closed terminal and the floating arm, the free terminal is connected to the floating arm, and the end terminal is connected to the free terminal and corresponds to the floating arm. The first elastic sheet has the merely one free terminal, and the second elastic sheet has the two free terminals and the two end terminals. The connector using the same can quickly conduct noise outside.
