Abstract: A printed circuit board includes a plurality of layer structures disposed in a stacked manner, and the printed circuit board has a disposing face. A differential pair unit and a shielding structure for shielding the differential pair unit are disposed on the disposing face. The differential pair unit includes two signal via holes, each signal via hole passes through the plurality of layer structures, and an anti-pad corresponding to each signal via hole is disposed on a ground layer through which the signal via hole passes. A part of metal of a ground layer is spaced between two anti-pads. Each signal corresponds to one anti-pad, and a ground layer is spaced between anti-pads.

Abstract: The technology of this application relates to a shielding piece, a female connector, and a connector assembly. The shielding piece includes a main body and a contact portion, and the contact portion is connected to the main body by using at least two elastic arms or a connecting portion. The connecting portion surrounds the contact portion, and forms, jointly with the contact portion, a convexity protruding from the main body. The at least two elastic arms are connected to the main body at a periphery of the contact portion along different directions, and a gap is formed between the main body and the at least two elastic arms. The contact portion is configured to abut against a ground terminal of a male connector.

Abstract: A connector includes an insulation base, a terminal array, a metal shielding piece, and a first common grounding conductor (CGC). The insulation base has two surface. The terminal array is fastened on the insulation base and includes many rows of terminals. Each row of terminals includes a signal terminal and a ground terminal, both which penetrate the insulation base, and a metal shielding piece is between two adjacent rows of terminals. The first CGC is on one surface, two through holes (THs) are on the first CGC, the signal terminal penetrates the first TH and is insulated from an inner wall of the first TH, the ground terminal penetrates the second TH and is in contact with and conducted with at least a part of an inner wall of the second TH, and the metal shielding piece is in contact with and conducted with the first CGC.

Abstract: A printed circuit board includes a connector insertion area including many rows of crimping holes, each row of crimping holes includes at least two pairs of signal crimping holes (SCHs), and each pair of SCHs includes two SCHs. In a row arrangement direction of the crimping holes, at least one ground crimping hole (GCH) is arranged on either side of each pair of SCHs. A depth of the GCH is greater than or equal to a depth of the SCH, the GCH includes a main hole and a shielding component on at least one side of the main hole, a part of a side wall of the main hole is a part of a side wall of the shielding component, and a sum of lengths of the main hole and the shielding component in a first direction is greater than a length of the SCHs in the first direction.
