Electrical connector

A system comprising:

• a piece of material that extends generally along a lateral direction;
• an electrical conductor that extends from the piece of material;
• and
• an electrical connector comprising a male element and female element configured to form a rivet for fastening the electrical connector to the piece of material,
• wherein the electrical connector further includes a neck washer comprising a washer portion and a neck portion, wherein the neck washer is monolithic so that the washer portion and the neck portion are physically interconnected, and wherein the neck washer is arranged between the male element and the female element of the rivet,
• wherein the electrical conductor comprises a loose end that extends from the piece of material along a longitudinal direction perpendicular to the lateral direction,
• wherein the loose end of the electrical conductor is clamped between the neck portion of the neck washer and the male element to form an electrical connection area configured to make electrical connection with the loose end of the electrical conductor of the piece of material,
• wherein, with the neck washer placed between the male element and the female element of the rivet:
• the washer portion extends radially away from the male element and the neck portion, and
• the neck portion extends in the longitudinal direction from an opening in the piece of material through which the male element extends toward the female element, is radially inward of the washer portion and radially outward of the male element of the rivet, and is arranged directly between the male element and an innermost radial surface of the female element in the lateral direction, and wherein the neck portion of the neck washer is configured to electrically connect the electrical conductor to at least one of the male element and the female element.
