Patent ID: 8167631

Claim:
A card edge connector serving as a female connector, said card edge connector comprising: a plurality of signal line contacts; and a plurality of ground contacts that are arranged in parallel in at least one row, wherein each of said plurality of signal line contacts includes a contact point portion adapted to contact an external contact point of a male connector at a desired contact pressure, an elastically deformable portion adapted to impart the desired contact pressure to the contact point portion, a fixing portion being held on the card edge connector, and a terminal portion being connectable to an external contact point of a printed wiring board on which the card edge connector is mounted, each of said plurality of ground contacts includes a contact point portion adapted to contact an external contact point of a male connector at a desired contact pressure, an elastically deformable portion adapted to impart the desired contact pressure to the contact point portion, a fixing portion being held on the card edge connector, and a terminal portion being connectable to an external contact point of a printed wiring board on which the card edge connector is mounted, the signal line contacts and the ground contacts are arranged in a way that every two signal line contacts for high-speed signals to send and return respectively there through are interposed between two grounds contacts, and all of the plurality of ground contacts arranged in the one row are electrically connected on one another through said fixing portions of said plurality of ground contacts by use of a plurality of common contacts, each of said plurality of common contacts includes a flat main body and two leg portions which are formed by bending right and left end portions of the flat main body, and each of said two leg portions is formed with two clamping portions clamping corresponding fixing portions of two ground contacts such as to electrically connect said two ground contacts between which the two signal line contacts are interposed.
