Electrical connector

A connector comprising:

• an insulating housing comprising a facing surface configured to face a circuit board;
• and
• a plurality of conductive contacts held by the insulating housing so as to align along an arrangement direction that is parallel to the facing surface,
• wherein the plurality of conductive contacts comprise:
• a first signal contact comprising a first connection portion configured to be connected to a first signal conductor of the circuit board and a first contact portion configured to contact a first mate signal contact of a mate connector;
• a second signal contact comprising a second connection portion configured to be connected to a second signal conductor of the circuit board and a second contact portion configured to contact a second mate signal contact of the mate connector;
• and
• a ground contact comprising a ground connection portion configured to be connected to a ground conductor of the circuit board and a ground contact portion configured to contact a mate ground contact of the mate connector,
• wherein the ground contact is located between the first signal contact and the second signal contact and extends to be perpendicular to the arrangement direction to form a partition wall between a first region including the first signal contact and a second region including the second signal contact,
• wherein the first connection portion and the second connection portion are located outside the insulating housing when viewed from a perpendicular direction that is perpendicular to the facing surface,
• wherein the ground contact comprises:
• a first partition portion extending to be perpendicular to the arrangement direction between the first connection portion and the second connection portion outside the insulating housing;
• and
• a second partition portion extending to be perpendicular to the arrangement direction between the first contact portion and the second contact portion inside the insulating housing, and
• wherein the ground connection portion is formed in the first partition portion, and the ground contact portion is formed in the second partition portion.
