Electrical connector for high-speed transmission

1 . A connector comprising:

a top pin group having a plurality of contact pins aligned in a predetermined direction; and

a bottom pin group having a plurality of contact pins aligned in the predetermined direction, the bottom pin group being arranged so as to face the top pin group and located on a substrate side,

wherein each of the contact pins is at least either one of a signal pin used for signaling and a ground pin used for grounding,

wherein the top pin group includes a double ground configuration in which sets of signal pins and ground pins are aligned adjacent to each other in the predetermined direction, each of the sets comprising two of the signal pins aligned between two of the ground pins, and

wherein the connector further comprises a conductive member electrically connected to adjacent two of the ground pins in the top pin group, the conductive member including a protruding shape arranged between adjacent two of the ground pins in the top pin group.

2 . The connector according to claim 1 used for high-speed transmission that is faster than or equal to 100 Gbps.

3 . The connector according to claim 1 , wherein the conductive member is electrically connected to each of the ground pins of the bottom pin group.

4 . The connector according to claim 1 ,

wherein each of the contact pins includes a mount portion mounted on a substrate, an erect portion erecting in substantially a vertical direction from the mount portion, and a substantially-straight portion extending in substantially a horizontal direction from the erect portion and including a contact point with a counterpart terminal, and

wherein the conductive member is electrically connected to the erect portion of each of the ground pins of the top pin group.

5 . The connector according to claim 4 , wherein the conductive member includes a dimension in a height direction that is larger than or equal to 50% of a dimension of the erect portion.

6 . The connector according to claim 4 , wherein the conductive member is electrically connected to a front face of the erect portion,

the connector further comprising a back face member that is located on a back face of the erect portion of each of the ground pins of the top pin group and holds the erect portion of each of the ground pins of the top pin group between the back face member and the conductive member.

7 . The connector according to claim 1 further comprising a housing that holds the top pin group and the bottom pin group,

wherein each of the contact pins extends outward such that a portion on a tip side including a contact point with a counterpart terminal is inclined from the housing, and

wherein a first wall extending in an extending direction of each of the contact pins and separating inclined portions of each of the contact pins extending outward from the housing from each other is formed in the housing.

8 . The connector according to claim 7 , wherein a second wall extending in the extending direction of each of the contact pins and facing an inner face of the inclined portion of each of the contact pins is formed in the housing.

9 . The connector according to claim 1 further comprising a housing that holds the top pin group and the bottom pin group,

wherein each of the contact pins extends outward such that a portion on a tip side including a contact point with a counterpart terminal is inclined from the housing, and

wherein an inclined portion of each of the contact pins extending outward from the housing includes a length that is larger than or equal to 2 mm from a root to the contact point.
