摘要： A color display tube (1) is disclosed having an improved suspension system of the color selection electrode (12). The positional stability of the color selection electrode (12) is of eminent importance for the color purity of the color display tube (1). If the color selection electrode (12) slightly shifts, the electron beams (7,8,9) may impinge on electroluminescent material of the wrong color, leading to discolorations. It is recognized that this positional stability is improved by applying free end portions (22) of a smaller diameter on the supporting elements (17) because this will lower the friction between the free end portions (22) and the suspension means (20). This smaller diameter has the disadvantage that the insertion of the color selection electrode (12) into the display window (3) of the color display tube (1) becomes more difficult. This invention solves this problem by applying free end portions (22), which are provided with a centering tip (44). In order to prevent scratches—which lead to loose particles in the color display tube (1)—when the color selection electrode (12) is inserted or extracted, the free end portion (22) is smoothly shaped.

摘要： A color display tube (1) is disclosed, which comprises an improved suspension system of the color selection electrode (12). The color display tube has suspension means that are constructed so as to be self-locking. The suspension means (20) are provided with an additional flat portion (31). This plate has an aperture (32) that is shaped such that it has at least three surfaces of engagement (42, 43) for the free end portion (22) of the supporting elements (17) connected to the inside of the upright edge (18) of the display window (3). When the color display tube is exposed to shock loading, the construction of the flat portion (31) is capable of absorbing this shock without the color selection electrode (12) becoming detached from the supporting elements (17). The action is based on the friction between the surfaces of engagement (42) and the free end portion (22). When a force is applied in the plane (47) of the resilient element (30), the suspension means (20) slip from their rest position and are locked by a surface of engagement (48), whereby the preload caused by the resilient element (30) and the spring (40) will cause the suspension means (20) to resume its original position. In this manner, a color display tube (1) with a good positional stability of the color selection electrode (12) is obtained. Furthermore, the color selection electrode (12) can be reclaimed in case the color display tube (1) is rejected because there is no need to weld the suspension means (20) to the free end portions (22) anymore.
