Abstract
The utility model relates to a metal cell -phone backshell. This metal cell -phone backshell's the metal main casing body is gone up to open has the through -hole, and the through -hole plastics of having moulded plastics form metal and plastics integration backshell. The through -hole is gone up along sky wire casing with edge down and the microscler hole that lies in metal cell -phone backshell upper end and lower extreme including lieing in metal cell -phone backshell. The utility model discloses metal cell -phone backshell owner's material is the metal, therefore feel is good, and it is good to dispel the heat, and specific position has set up the through -hole on the backshell, and the through -hole location plastics of having moulded plastics form metal and plastics integration backshell, avoids the cell -phone signal shielding phenomenon that the all -metal backshell leads to.
Description
Technical field
The utility model relates to a kind of metallic mobile phone back cover.
Background technology
In today that mobile phone industry develops increasingly, we not only see the innovation day by day of technology, more see mobile phone market keen competition.In mobile phone industry, emerge much outstanding cell phone manufacturer, impel mobile phone industry constantly to compete, development, and then impel whole mobile phone industry to achieve in development in science and technology to stride forward greatly.Existing mobile phone battery cover major part is plastics back cover, and the great advantage of plastics back cover is that signal can not conductively-closed, but plastics matter is soft, texture is not good, can only play cover and decoration function mobile phone, and plastics not easy heat radiation, has a strong impact on the life-span of mobile phone CPU simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of metal mobile phone battery cover integrated with plastics.This metallic mobile phone back cover is using metal as main body, and metal master shell has through hole, and through hole is injected with plastics, the metal back cover integrated with plastics of formation, and texture is excellent, and heat dispersion is strong, does not affect mobile signal quality simultaneously.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of metallic mobile phone back cover, comprise master metal housing, master metal housing has through hole, and through hole is injected with plastics, forms metal back cover integrated with plastics.
Further, described through hole comprises the antenna slot of metallic mobile phone back cover.
Further, described antenna slot is positioned at edge and lower edge on metallic mobile phone back cover.
Further, on described metallic mobile phone back cover, edge and lower edge respectively have two antenna slots in left and right.
Further, described through hole comprises each elongated hole of metallic mobile phone back cover top and bottom.
Further, the metallic member of described metallic mobile phone back cover is the aluminum alloy base material with nanometer micropore.
Further, described plastics are any one in PBT, PPS, PET.
For the metallic mobile phone back cover of aluminum alloy material, metallic mobile phone back cover preparation method of the present utility model can carry out as follows:
(1): processed by CNC, the elongated hole of the empty aluminium alloy main casing of milling and antenna slot position;
(2): step (1) gained aluminum alloy base material is hung on special hanger, according to ultrasonic degreasing, washing, alkaline etching, washing, table is adjusted, the sequencing of washing carries out pre-treatment to aluminum alloy surface;
(3): the semi-finished product that step (2) obtains are carried out anodic oxidation by sulfuric acid solution anodizing tank, sulfuric acid concentration is 160 ~ 300g/L, voltage is 10 ~ 35V, processing time 10 ~ 60min, obtain the oxidation film layer aluminum alloy base material of surface containing nanometer micropore, the oxidation film layer thickness of nanometer micropore is 3 ~ 50
μm;
(4): semi-finished product step (3) obtained immerse
pHbe 8.5 ~ 13, based on sodium metal ion, containing in the solution of one or more sodium salt mixts, obtain the aluminum alloy base material with corrosion nanometer micropore, the time of immersion is 50 ~ 800s, need repeat to immerse taking-up 3 ~ 8 times, cleans up after each taking-up with water;
(5): the semi-finished product that step (4) is obtained by casting resin body, as the resinites such as PBT, PPS, PET obtain the metal product integrated with resin.
The utility model has following beneficial effect:
Metallic mobile phone back cover of the present utility model has through hole, through hole is injected with plastics, forms metal back cover integrated with plastics, because main material is metal, therefore texture is good, dispel the heat good, grade is high-end, because on back cover, ad-hoc location is provided with through hole, lead to the hole site is injected with plastics, avoid the mobile phone signal shielding phenomenon that all-metal back cover causes, and mobile phone can be made lighter, do not affect again the texture of mobile phone, and play certain decoration function.
