1. A strain relief plug to restrict movement of one or more lead wires on a printed circuit board, the strain relief plug comprising:
an elongated stem along a vertical axis normal to a plane of the printed circuit board;
an in-board flange defined by the elongated stem, the in-board flange configured to seat in a bore defined by the printed circuit board;
an anchor defined by a first end of the elongated stem configured to prevent the strain relief plug from releasing from the printed circuit board; and
a bar defined by a second end of the elongated stem and transverse the vertical axis, the bar and the elongated stem configured to form one or more lead wire channels to trap and apply pressure to the one or more lead wires between the bar and the printed circuit board and, in turn, strain relief the one or more lead wires.
