Filament F, an end is fixed in pillar 121, and the other end then is fixed in the elastic portion 1221 of fixture 122, and gives its predetermined tension force by elastic portion 1221.From the electronics that filament F is emitted, to be controlled by grid 2, the fluorophor (not shown) that will be formed at the anode of substrate 1 by its mesh portion 22 encourages and carries out luminous.
And grid 2 is not limited to mesh configuration, and for example curtain columnar structure etc. has the article with lead-in opening structure that electronics is passed through and gets final product.Therefore will have the article with lead-in opening structure that electronics can pass through and be called mesh configuration.
Because will be made as grid 2 and vibrationproof member 3, in that to open the width (length) of the direction of set direction quadrature identical with filament F, and be identical with the height setting of the portion of holding up 211,312 of these tabs, so as described later, can form simultaneously on a slice metallic plate, both tab is shaped simultaneously and portion of holding up 211,311 and fixed part 212,312 are shaped.And because the width of the aforementioned direction of vibrationproof member 3 can be not bigger than the width of the aforementioned direction of the edge portion 23 of grid 2, so dead space is increased.In addition, if make the tab 21 of grid 2 and the tab 31 of vibrationproof member 3 be arranged in a row (or if making aligned in position of above-below direction tab), just then the bending machining of tab can become easy with crooked processing with mould as Fig. 1 (a).
The size and shape of grid 2 is looked the literal of demonstration and the pattern of figure (display pattern) and is become, and the arrangement of similarly a plurality of grids 2 also can be looked display pattern and become.On the other hand, vibrationproof member 3 is because be configured between grid 2 and the grid 2, so the Pareto diagram that its allocation position also can the grid utmost point 2 and becoming.Vibrationproof member 3 allocation positions among Fig. 1 are the one example.
The allocation position of vibrationproof member 3, though the Pareto diagram of the grid utmost point 2 and becoming, but because vibrationproof member 3 as the some of the Pareto diagram of grid 2 side by side integrally formed with a slice metallic plate and grid 2, so when vibrationproof member 3 is installed on substrate 1, do not need independent vibrationproof member 3 location that are.Therefore, the present invention makes the formation operation of vibrationproof member 3 and the installation exercise of substrate 1 is simplified and becomes easy.
In Fig. 1 (a), the 1st row, the 2nd arranges the grid 2 and vibrationproof member 3 of (going up hypomere 2 rows), also can form 2 row's parts simultaneously.When the 1st row, the 2nd row's gate pattern was identical during this situation, vibrationproof member 3 just can integrally formed 2 row's parts.
The 2nd embodiment
Fig. 2 represents the embodiment of vibrationproof member involved in the present invention.
Fig. 2 (a) to (d) represents the expanded view before each vibrationproof component forming.In addition, symbols such as broken curve only are recorded in initial accompanying drawing, then omit in other accompanying drawing.
The example of Fig. 2 (a) is configured as vibrationproof portion 32 with being connected partly of vibrationproof portion 32 and tab formation portion 33 along broken curve X2 warpage, and with broken curve X3, X4 part warpage and the portion of holding up 311, the fixed part 312 of shaping tab 31.At this moment, if the width W 2 of width (length) W1 that the filament of vibrationproof portion 32 is opened set direction and tab formation portion 33 is set at W1＜W2 (or W1=W2) at least, then the warpage of broken curve X2 part just can become easy.In the present embodiment, use the metallic plate of the about 0.05mm of thickness of slab, and setting width W 1 is about 1.5mm for about 0.45mm, width W 2.
Example shown in Fig. 2 (b) forms slit S11, S12 at broken curve X2 part (coupling part of vibrationproof portion 32 and tab formation portion 33) residual continual-connecting-part 351, partly forms slit S21 at broken curve X3, partly forms slit S22 at broken curve X4.In addition, bight part of vibrationproof portion 32 is formed with circular corner cut 34.When figure (b), by forming slit S11, S12, and the cause that the vibrationproof portion 32 and the continual-connecting-part that is connected part of tab formation portion 33 are diminished, so the warpage of broken curve X2 part is become easily, even and the width of the width of vibrationproof portion 32 and tab formation portion 33 is set as than Fig. 2 (a) is littler also can be easy to warpage.In addition, make the warpage of tab 31 parts become easy by forming slit S21, S22.And, because be formed with the cause of circular corner cut 34 the bight of vibrationproof portion 32 part, when being installed on pillar and fixture giving predetermined tension with filament, that is when opening of filament established operation, filament can not caught on or catch on and cut off by bight part of vibrationproof portion 32.Therefore opening of filament established operation and become smoothly and easily.

The 3rd embodiment
Fig. 3, Fig. 4 represent the formation step and the forming step of grid of the present invention and vibrationproof member.
The formation step of grid and vibrationproof member at first, is described with Fig. 3.
Shown in Fig. 3 (a),, will form (at the inboard mesh pattern shape that forms of single chain line) as the etched pattern of grid 2, vibrationproof member 3 such as the dotted line at metallic plate MP (for example SUS304 (stainless steel) thickness of slab 0.05mm).Also be about to a plurality of grids 2 and carrying out pattern-forming with a slice metallic plate MP simultaneously with vibrationproof member 3.Also determined the installation site of vibrationproof member 3 by this pattern-forming.The metallic plate MP that has been formed with etching resistance agent pattern with carry out etching and launch, make being linked to just like the state of a plurality of grids 2 shown in Fig. 3 (b) with vibrationproof member 3 relative a pair of be that the shaping of sheet 41 is with launching part 4.Grid 2 and vibrationproof member 3 launch part 4 by the shaping usefulness that forms of the one with a slice metallic plate MP.In Fig. 3 (b), grid 2 and vibrationproof member 3 be that the be orthogonal length setting of tab 21 and the tab 31 of vibrationproof member 3 of the width of direction of (or open set direction with filament be orthogonal) and grid 2 of sheet 41 is identical.
The shaping of Fig. 3 (b) uses mould to form as illustrated in fig. 4 with launching part 4.
In Fig. 4, Fig. 4 (a) is illustrated in the section of the X5 part of Fig. 3 (b) along the arrow direction.
At first, the shaping of Fig. 3 (b) is with launching part 4, shown in Fig. 4 (b), with the broken curve X2 part warpage of Fig. 3 (b) and shaping vibrationproof portion 32, secondly shown in Fig. 4 (c), with the broken curve X3 part warpage of Fig. 3 (b) and shaping tab 31 (tab 21), for another example shown in Fig. 4 (d), with Fig. 3 (b) broken curve X4 part warpage and the portion of holding up 311, the fixed part 312 (portion of holding up 211 of tab 21, fixed part 212) of shaping tab 31.During with broken curve X3, X4 part warpage, the tab 21 of grid 2 and the tab 31 of vibrationproof member 3 are shaped simultaneously.
The fixed part 212,312 of the grid 2 of the formation of parts of Fig. 4 (d) and the tab 21,31 of vibrationproof member 3 is bonding and be installed on substrate 1, will be that sheet 41 cuts off after it is installed.
Through the vibrationproof member 3 of the step made of Fig. 3, Fig. 4 because use the cause of the metallic plate identical with grid 2, its thickness of slab is 0.05mm, become as thin as a wafer, but because vibrationproof member 3 only contacts with filament when filament vibrates, different with the member of as the pillar of filament or fixture, filament being supported, so the cause that does not need hard intensity is even thin also not influence.Therefore, vibrationproof member 3 can be made of the metallic plate identical with grid 2.
When Fig. 3, Fig. 4, using the identical metallic plate of a slice to make a plurality of grids and the utilization of vibrationproof member is that the shaping of the sheet state that forms binding is with the expansion part, and utilize this shaping the tab of a plurality of grids and vibrationproof member to be shaped simultaneously with the expansion part, and the fixed part of these tabs is bonding simultaneously and be installed on the cause of substrate, so can make formation step, the forming step of grid and vibrationproof member, the operation minimizing of installation steps.In addition, the vibrationproof member is installed on the position of substrate, and the cause that then yet can determine inevitably when the decision of the installation site of grid is not so the vibrationproof member needs independently to locate.
The 4th embodiment
Fig. 5 to Fig. 7 represents the formation step and the forming step of vibrationproof member and this vibrationproof member and the grid of the present invention the 4th embodiment.
At first the vibrationproof member is described with Fig. 5.
Fig. 5 (a) is a side view, and Fig. 5 (b) is a plane graph, and Fig. 5 (c), Fig. 5 (d), Fig. 5 (e1), Fig. 5 (e2) are the location diagrams of explanation filament.
Among Fig. 5 (a), Fig. 5 (b),, be formed with the peristome (eel-like figure portion) 321 that filament F is passed through in the vibrationproof portion 32 of vibrationproof member 3.Peristome 321 forms the shape that filament F is impaled from 3 directions as U word shape, V word shape, semiellipse shape etc.
The vibrationproof portion 32 of the 1st embodiment to the 3 embodiment forms the face that filament F is contacted smooth, though at filament F towards upper and lower during to (direction vertical) vibration with the substrate 1 of Fig. 1, prevent that it from contacting with grid etc., but filament F also can be toward transverse direction (direction parallel with the substrate 1 of Fig. 1) and these third sides to vibrating.That is filament F 360 degree directions around filament F are vibrated.In addition, the vibration of filament F is except because producing, also have situation about producing because of filament F vibration frequency and the interference of fluorescent display tube driving frequency from vibration that the fluorescent display tube outside applied.In the latter's situation, though vibration amplitude is so not big, can produces flicker and make display flashing, make the display quality reduction.
Present embodiment vibrationproof portion 32, because be formed with the peristome 321 that filament F is impaled from 3 directions, even so filament F any direction vibration such as direction or transverse direction up and down, also because filament F understands the cause of contact openings portion 321 bottom surfaces or side, and the vibration of attenuating filament that can be certain.In addition, shown in Fig. 5 (c), by often making the side of filament F contact openings portion 321, also can lower the small amplitude motion that becomes the flicker reason.Therefore, when the doubt situation that produces the less vibration of the amplitude become the flicker reason is arranged,, filament F is often contacted with opening 321 sides, then can effectively prevent its vibration if shown in Fig. 5 (c).
And, when filament F contacts with vibrationproof portion 32, though its contact part temperature can reduce and the electronics discharging amount also can reduce, for example under situation shown in Figure 1, because its contact partly position in the centre of adjoins gate and the position outside the viewing area, so do not hinder to showing.
Be provided with many filaments though fluorescent display tube is generally all opened, all filaments all opened be located at identical height its difficulty is arranged, how many height has different situation with filament.If the filament height is different, then has and look filament and the different situation of vibration-isolating effect.For example, shown in Fig. 5 (d), when observing with regard to the different situation of height H 1, the H2 of 2 filament F1, F2, do not form peristome 3211,3212 in vibrationproof portion 32, and when plane with these peristome bottom surface height H 3 equal heights is only arranged, when filament F1, F2 up-down vibration, though filament F1 can contact with vibrationproof portion 32, filament F2 then has discontiguous situation.
In aforesaid situation, if peristome 3211,3212 is set shown in Fig. 5 (d), contact because of the side of meeting when then filament F1, F2 vibrate, so vibration is lowered with peristome 3211,3212.Therefore, even peristome 3211,3212 is still effective as filament vibrationproof means when the height of a plurality of filaments is different.
If peristome is set, then because the needs that make filament consistent with the peristome position are arranged, so the needs that filament correctly are installed on the precalculated position are arranged in vibrationproof portion.Corresponding means when this illustrates the offset of filament and peristome with Fig. 5 (e1), (e2).And Fig. 5 (e1), Fig. 5 (e2) are plane graphs.
Fig. 5 (e1), Fig. 5 (e2), peristome 321 is provided with a plurality of (figure is 3) in a place, in Fig. 5 (e1), (e2), when the position of filament when opening the parallel direction skew of set direction with filament, for example filament Fa position is when the offset of filament Fb, and filament Fb just can engage with adjacent peristome 321.Therefore when Fig. 5 (e1), (e2), though opening of filament establish the position a little skew arranged, also can be with filament by (embedding) peristome 321.
Whether as shown in Figure 5, the vibrationproof portion of vibrationproof member be provided with peristome, with and the peristome side whether should often make the filament contact, at the drive condition of the place of considering to be provided with fluorescent display tube and environment, fluorescent display tube etc., and consider to select to get final product after the magnitude of vibrations that takes place and the kind.
