Description

Zirconia ceramics U-shield box back board structure

Technical field

The U-shield box back board structure of the utility model and a kind of zirconia ceramics, especially a kind of 5G-U-shield box backboard belong to In U-shield accessory technical field.

Background technology

U shields are the smart machines for protecting Web bank's client secure, include mainly that intelligent chip and shape are similar With the hardware in kind of flash memory, including a U-shield box；The U-shield box is the shell made of box body and backboard configuration, usual U The enclosure material selection of shield box nearly all uses plastic material.This plastic shell is although at low cost, is easy molding making, but matter Feel bad, it is more dull, even if the different designs element such as decorative pattern or simulated leather is added, but it is still more inferior for feel； Especially plastic shell is easily deformed the defects of equal there is also difference of hardness, and be also easy to make the internal intelligent chip installed by To the interference of external electromagnetic, increase the loss of electric signal, safety is poor.

Invention content

The purpose of the utility model is to overcome the shortcomings of the prior art, and it is simple to provide a kind of production method, system Make efficient, at low cost, density is high, and intensity is good, and electromagnetic interference is few, and electric signal loses small, the good zirconia ceramics U-shield of safety Box back board structure.

To achieve the above object, the utility model adopts the following technical solution：A kind of zirconia ceramics U-shield box backboard knot Structure, including one is being arranged corresponding to U-shield box body, shape is rectangular U-shield box backboard, four corners of the U-shield box backboard There are arc transition connection, the U-shield box backboard to be formed using compound zirconia material injection molding, the U-shield box backboard Inner face is provided with rectangular concave lacking groove, and forms the moulding that surrounding encloses, and the outer face surface of the U-shield box backboard has essence It grinds superficial layer and transits to inner face edge with arc surface at four edges.

As preferred：Four edges of the U-shield box backboard are provided with arc surface transition and form the V-shaped of an evagination Four peripheries；One upper end side of centre of the U-shield box backboard at least provided with a round or Ω type preformed holes, the concave lacking groove End edge is provided with the preformed hole of strip in side；The thickness of the U-shield box backboard is 1.25-3mm, wherein notch groove depth In 0.8-2mm；Uniformly be parallel in the groove bottom of the concave lacking groove long side or in it is criss-cross, be highly not more than 0.1mm A plurality of shallow rib.

The utility model belongs to improvements over the prior art, it has production method simple, and producing efficiency is high, at low cost, The features such as density is high, and intensity is good, and electromagnetic interference is few, and electric signal loss is small, and safety is good.

Fig. 1 is the inner face structural schematic diagram of the utility model.

Fig. 2 is the formation outside schematic diagram of the utility model.

Fig. 3 is the one side structural schematic diagram of the utility model.

Specific implementation mode

The utility model is described in detail below in conjunction with attached drawing：Shown in Fig. 1-3, one kind described in the utility model Zirconia ceramics U-shield box back board structure, including one is being arranged corresponding to U-shield box body, shape is rectangular U-shield box backboard 1, institute Four corners for stating U-shield box backboard 1 have the connection of arc transition 2, the U-shield box backboard 1 to use compound zirconia Material injection It is molded with, the inner face of the U-shield box backboard 1 is provided with rectangular concave lacking groove 3, and forms the moulding 4 that surrounding encloses, institute The outer face surface 5 for stating U-shield box backboard 1 has lappingout superficial layer and transits to inner face edge in four edge arc surfaces 6.

As shown in the figure, four edges of the U-shield box backboard 1 are provided with 6 transition of arc surface and form the V words of an evagination Four peripheries 7 of shape；One upper end side of centre of the U-shield box backboard 1 is described recessed at least provided with a round or Ω types preformed hole 8 End edge is provided with the preformed hole 9 of strip in the side of short slot；The thickness of the U-shield box backboard 1 is 1.25-3mm, concave 3 depth of short slot is in 0.8-2mm；Uniformly be parallel in the groove bottom of the concave lacking groove 3 long side or in criss-cross, height A plurality of shallow rib 10 no more than 0.1mm.

Embodiment：The utility model is using conventional compound zirconia material injection molding, and manufacture craft is simple, efficiency Height, at low cost, elasticity modulus is more than 195Gpa, and Vickers hardness is more than 1200Kgf/mm2, and density is more than 5.98g/cm3, stomata Rate is less than 0.3%.
