A convergence cup for use in color kinescopes includes an improved shield structure for magnetically separating the pairs of pole pieces. The one-piece shield is formed from a single metal strip with tabs at its ends by bending it 180 DEG along a lateral line and cutting from the strip a third tab extending from the bend line, and bending the resulting legs 120 DEG outwardly along central lateral lines to form a Y-shaped shield. The one-piece shield is then secured in position inside the cup by spot welding the tabs to the cup wall.
