An apparatus may include a conductive wire and a plug. The plug may be electrically and mechanically coupled to the conductive wire. The plug may include a non-conductive overmold, an electrically conductive barrel, and a lip. The non-conductive overmold may surround the conductive wire. The electrically conductive barrel may extend from the overmold, and may have a width that is smaller than a width of the overmold. The lip may extend from the barrel in a direction substantially perpendicular to a direction in which the barrel extends from the overmold. A distance from an outer portion of the lip to an opposite outer portion of the lip may be at least twice a length that the barrel extends from the overmold.
