A grounding component for electrically grounding a connector installed at an edge of a printed circuit board, wherein said grounding component is formed as a single sheet of bent metal and wherein the grounding component comprises: - a frame configured to be positioned around an opening of said connector, the opening of the connector being configured to be accessible from an outside of a device once said connector is installed in said device, the connector having an electrically conductive part formed by surrounding electrically conductive rims (214, 216, 218, 220) among which at least two side rims (214, 220); - a return configured to be positioned over a surface of the connector that is perpendicular to the opening of said connector, the frame and the return giving a substantial L-shape to the grounding component; - each of two sides (150, 160) of the frame that are positioned around the opening of the connector comprising a first retaining element, being configured to be positioned on a rear face, with respect to the opening of the connector, of a corresponding side rim (214, 220) of the connector, the first retaining element being configured to establish electrical contact with the electrically conductive part of the connector when said grounding component is mounted on the connector; - a further side of the frame furthest from the return, said further side being configured to be positioned on a rear face, with respect to the opening of the connector, of at least one corresponding rim (216, 218) of the connector when the grounding component is mounted on the connector; - the first retaining element, the further side, and the return being configured to cooperate to maintain the grounding component in its mounting position once the grounding component is mounted on the connector. - a frame configured to be positioned around an opening of said connector, the opening of the connector being configured to be accessible from an outside of a device once said connector is installed in said device, the connector having an electrically conductive part formed by surrounding electrically conductive rims (214, 216, 218, 220) among which at least two side rims (214, 220); - a return configured to be positioned over a surface of the connector that is perpendicular to the opening of said connector, the frame and the return giving a substantial L-shape to the grounding component; - each of two sides (150, 160) of the frame that are positioned around the opening of the connector comprising a first retaining element, being configured to be positioned on a rear face, with respect to the opening of the connector, of a corresponding side rim (214, 220) of the connector, the first retaining element being configured to establish electrical contact with the electrically conductive part of the connector when said grounding component is mounted on the connector; - a further side of the frame furthest from the return, said further side being configured to be positioned on a rear face, with respect to the opening of the connector, of at least one corresponding rim (216, 218) of the connector when the grounding component is mounted on the connector; - the first retaining element, the further side, and the return being configured to cooperate to maintain the grounding component in its mounting position once the grounding component is mounted on the connector.
