Described back cover is the rectangular plate shape structure, is equipped with a square groove 2 in the interposition of plate, pulls for the staff button, is convenient to plasma display system be mentioned and put down.In addition, on the rectangular slab of the relative both sides of described groove 2, be provided with louvre 3, plasma display system can be better dispelled the heat, and make poroid so electric zine plate back cover, save material more.
Be provided with the bar shaped fixed head 4 vertical in the inboard of described back cover 1, back cover is played fixation, prevent that poroid back coverboard is damaged with described rectangular recess 2.
Described back cover 1 dual-side also is respectively equipped with strip groove 5, in described groove 5, be interval with several joining holes 6, this joining hole 6 in order to display device in the tipping of set component groups join, specifically, this joining hole can adopt in spiro connection structure and the display device set component groups to be hinged with to join; The back cover 1 of described plasma display system can adopt impact style to make in process of production.
It is as follows that modified of the present invention electricity zine plate is applied to the beneficial effect that produced on the back cover of plasma display system:
Common electric zine plate has intensity and surface quality and electric conductivity preferably, but show by a large amount of tests, common electric zine plate can not satisfy the requirement of all tv products, especially large-sized plasm TV product, therefore, it is impracticable directly adopting current material to be applied on the plasma product.Want successful Application on plasm TV, the final purpose that realizes falling cost, the moulding that must satisfy the plasm TV back cover requires (punch process is good, damage resistant), EMC test request (electric conductivity will be got well).
The present invention is improved the performance of material by the trade mark of the selection electricity zine plate material of science.Die trial test and electric performance test through too much taking turns, electric zine plate material to the existing trade mark repeatedly improves, finally made the qualified steel plate back cover that satisfies test standard, determine that the electric zine plate that adopts is the SECC-N5 (mechanical property and electric conductivity are improved) of 0.47mm, electric zine plate after employing improves has satisfied the requirement that stretches makes back cover in punching course, four bights of back cover are not easy by drawing crack, and its mouldability has obtained improving greatly; Adopt the electric zine plate after improving to satisfy requirement on electric performance (as Fig. 2) equally; In addition, electric zine plate as base material is not limited in the SECC-N5 type, the electric zine plate of selecting other reasonable trade mark is also by after the measure improvement current material performances such as raising yield tensile ratio, can satisfy the especially requirement of punching press of mechanical property equally, and the electric zine plate material after improving there is good versatility to the back cover of size dimension plasma display system.
After the present invention adopts the original aluminium sheet of follow-on electric zine plate material substitution, greatly reduce the production cost of plasma display system back cover, finally make it on tv product, to obtain high volume applications.Present this technology successful Application on Hisense's plasm TV product, organic type and the new product that just dropped into have all adopted this lower cost materials, make enterprise occupy favourable cost advantage in market competition.
Except the improvement on the material, the back cover of plasma display system of the present invention also greatly reduces on materials, compares with aluminium sheet, and the thickness of plasma display system back cover of the present invention can reduce one times, greatly reduces cost.For example: 42 cun PDP products are sold 30,000 meters per year, as use the benefit that this technology can realize 900,000 yuan of cost savings every year.If 50 cun are sold according to 10,000 meters in PDP product year, the then annual benefit that can realize 550,000 yuan.
Abovely technical scheme of the present invention is described in conjunction with preferred embodiment; do not limit protection scope of the present invention with this; those skilled in the art is under the situation that does not deviate from inventive concept; embodiments of the invention are done to be equal to the replacement and the change of purpose; as the yield tensile ratio of the selected base material of electric zine plate of the present invention numerical value about near 0.7; the subtle change of electricity zine plate thickness between 0.45～0.6 all should be covered by among protection scope of the present invention.
