Document Type and Number:
WIPO Patent Application WO/2023/273757
Kind Code:
A1
Abstract:
Disclosed in the present application are a printed circuit board and an electronic device. The printed circuit board comprises a connector plugging area, wherein a plurality of rows of crimping holes are provided in the connector plugging area; each row of crimping holes comprises at least two pairs of signal crimping holes arranged at intervals; each pair of signal crimping holes comprises two signal crimping holes; the row arrangement direction of the crimping holes is a first direction; one grounding hole group is provided, in the first direction, on each of the two sides of each pair of signal crimping holes; the grounding hole group comprises a grounding crimping hole and a ground hole located on at least one side of the ground crimping hole; at least one shielding hole is further provided between the two signal crimping holes in each pair of signal crimping holes; and the grounding crimping holes, the ground holes and the shielding holes are all grounded and jointly surround the signal crimping holes. Therefore, an electromagnetic field of one pair of signal crimping holes is limited within a certain range, thereby reducing signal crosstalk between each pair of signal crimping holes, such that a high-speed signal can meet a corresponding transmission requirement when being transmitted in the printed circuit board.
