Connector

A connector comprising:

• two by N contacts arranged in two columns and N rows, where N is an integer of three or more,
• wherein N contacts in each column are arrayed at a predetermined contact-to-contact pitch in a first direction parallel to each column within a corresponding one of column areas each extending in the first direction and having a predetermined width in a second direction perpendicular to the first direction,
• wherein a distance between two contacts in one endmost row in the first direction among the N rows is larger than a distance between two contacts in each of the other rows and is different in length from the predetermined contact-to-contact pitch, and
• wherein a distance between two contacts in the other endmost row in the first direction among the N rows is smaller than a distance between two contacts in each of the other rows and is different in length from the predetermined contact-to-contact pitch.
