The granted patent (Publication Number: US11929567B2) discloses a card edge connector with a unique design to improve signal transmission and grounding. The connector includes a housing with two elongate walls and a card slot between them. Two rows of terminals are arranged on the walls, with signal and grounding terminals each having contacting and soldering portions. The soldering portions are organized into pairs, with most pairs consisting of a signal terminal and a grounding terminal, while the remaining pairs are either two signal terminals or two grounding terminals. This configuration aims to enhance the efficiency of signal transmission and grounding within the connector.

Furthermore, the patent describes another embodiment of the card edge connector with a similar design but a different arrangement of terminal pairs. In this version, the soldering portions of terminal pairs are aligned within each row but offset from adjacent pairs, creating four rows of soldering portions. The majority of terminal pairs consist of a signal terminal and a grounding terminal, while the rest are either two signal terminals or two grounding terminals. This innovative layout of terminal pairs aims to further optimize signal integrity and grounding performance in the card edge connector.
