Embodiment
With reference to figure 2, backlight assembly 100 of the present invention comprises a plurality of fluorescent tubes 10 and a low compressing tablet 20, though will be appreciated that in the present embodiment and do explanation with backlight assembly, the formation of low compressing tablet 20 of the present invention also need be fixed in the light source of a plurality of fluorescent tubes applicable to other.
As shown in Figure 2, low compressing tablet 20 can be divided into one first side plate 21, a base plate 22 and one second side plate 23, block rubber 13 butts of first side plate 21 and fluorescent tube 10 wherein, and than second side plate 23 more near the body 12 of fluorescent tube 10, a plurality of groove 21a are set on first side plate 21, and the position of groove 21a is corresponding with electrode 11 positions of fluorescent tube 10 respectively, to support respectively and keeper electrode 11; Base plate 22 is connected with first side plate 21, forms a salient point (rib) 22a respectively in the both sides of groove 21a, and strengthening the intensity of low compressing tablet 20, and may command adds tin 30 scope in man-hour; Second side plate 23 is connected with base plate 22, and also is formed with a plurality of groove 23a thereon, and its position is corresponding to the position of the groove 21a on first side plate 21, to support respectively and keeper electrode 11.
Will be appreciated that low compressing tablet 20 can be made of copper, and its section is the U font,, and can increases the intensity of low compressing tablet 20 with compressed side hem width degree; Again, first side plate 21, base plate 22 and second side plate 23 can be integrally formed.
In addition, in Fig. 2, groove 21a, 23a are the U font, but are not limited to this, and with reference to figure 3, groove 21a ' also can be the V font; Again, in Fig. 2, on first side plate 21 and second side plate 23, be equipped with groove, but be not limited to this,, also can only on the first side plate 21a, form groove 21a ' with reference to figure 3.
