Electrical connector

A connector comprising:

• a plurality of signal contacts aligned along an arrangement orientation, each of the plurality of signal contacts extending along an extending orientation crossing the arrangement orientation and comprising:
• a connecting portion configured to be connected to a signal conductor of a coaxial cable;
• and
• a contacting portion extending from the connecting portion along the extending orientation and configured to contact a mate signal contact of a mate connector;
• a plurality of conductive ground contacts each extending along the extending orientation and comprising:
• a ground connecting portion configured to be connected to an outer conductor of the coaxial cable;
• and
• a ground contacting portion extending from the ground connecting portion along the extending orientation and configured to contact a mate ground contact of the mate connector;
• an insulating housing holding the plurality of signal contacts and the ground contact;
• and
• a conductive shell covering at least a portion of the insulating housing around the extending orientation,
• wherein the plurality of signal contacts include a plurality of pairs of signal contacts,
• wherein the ground contacts and the plurality of pairs of signal contacts are arranged alternately along the arrangement orientation,
• wherein the shell comprises a plurality of projecting portions respectively corresponding to the plurality of ground contacts,
• wherein each of the plurality of projecting portions is in contact with a corresponding ground contact of the plurality of ground contacts, and
• wherein each of the plurality of projecting portions and the corresponding ground contact form a wall extending along the extending orientation between two adjacent pairs of the plurality of pairs.
