Each passageway defines a first stopping shoulder adjacent to the second surface and a second stopping shoulder adjacent to the first surface. The stopping ribs are lodged against the first stopping shoulder or the spring ribs are lodged against the second stopping shoulder so that the terminals are moveable limited in the passageways.

Abstract: An electrical connector includes a shielding cage, an insulative housing disposed within the shielding cage, at least two rows of terminals secured in the insulative housing and a metal sheet embedded in the insulative housing and disposed between the rows of terminals. An insulative housing defines a mating face and a mounting face perpendicular to the mating face. The metal sheet extends from the mating face to the mounting face and comprises at least one tail extending beyond the mounting face.

Abstract: An electrical connector assembly includes a first and a second electrical connector each having two connector ports. The first connector port of the first connector has an insulating mating tongue with a plurality of contacts thereon and an insulating protecting frame arranged side by side with the mating tongue along a longitudinal direction of the first connector and spaced away from the mating tongue. The second connector port is received in the protecting frame and has a shielding shell surrounding therearound.

Abstract: An electrical connector includes an insulating seat loaded with a circuit card therein. The circuit card includes a mating end intended to engage with a complementary connector and a terminal end intended to connect with cables. The mating end includes a row of conductive pad exploding to a first surface thereof. The row of conductive pad includes grounding pads and pairs of differential signal pads between every two of the grounding pads.

Abstract: A battery holder for a button-type battery (1) includes a holder body having a base wall (100) thereof for receiving the battery, and positive and negative terminals (20, 30) assembled to the holder body. The negative terminal has short and long spring elements (311, 315) defining first and second supporting point (311A, 315B) respectively, such that in an initial released position, the button-type battery is lifted up by the first and second supporting points bearing against the base wall, and in a fully released position, that battery is lifted by the second supporting point against the base wall with the first supporting point leaving away from the base wall. The above spring elements provides two-stage elastic forces, for ease of the user to release the battery from the battery holder.
