Embodiment 1

[0018] Figure 1a A schematic diagram of the metal casing in Embodiment 1 of the present invention is shown. Such as Figure 1a As shown, there is a gap on the metal shell 1; the gap is filled with an insulator 3, and the insulator 3 includes a plastic material, a first pigment and a second pigment, wherein the first pigment is used for the plastic material Coloring, so that the insulator 3 presents the same color as the finished metal shell (the color layer 4 can be formed in the area of ​​the metal shell without gaps through a surface treatment process, thereby obtaining the finished metal shell), and the second pigment is used In order to change the luster of the plastic material, the insulator 3 has the same metallic luster as the finished metal shell.

[0019] The mass percentage of the first pigment in the insulator 3 is 0.1%-0.5%, the mass percentage of the second pigment is 0.1%-1%, and the rest is plastic material. The plastic material includes polyphenylene sulfide ...

Embodiment 2

[0027] Figure 2a A flow chart of the manufacturing method of the metal shell in the second embodiment of the present invention is shown. This method is applicable to the situation of preparing the metal shell in the above-mentioned embodiment, such as Figure 2a As shown, the manufacturing method of the metal shell comprises the following steps:

[0028] Step 110, machining gaps at the set positions of the metal shell.

[0029] Figure 2b It shows a schematic diagram of the metal shell processed with gaps in the manufacturing method of the metal shell provided in the second embodiment of the invention. Such as Figure 2b As shown, taking the back shell of a smart phone as an example, a through channel extending from the first surface of the back shell to the second surface is respectively opened at the top and bottom of the metal shell 1 as the gap 2, thereby destroying the metal shell 1. The closure of the housing 1.

[0030] Optionally, a slit can also be provided at ...

Embodiment 3

[0054] This embodiment provides a mobile terminal, which includes the metal casing as described in the above embodiments, and components for supporting the normal operation of the mobile terminal. Exemplarily, the mobile terminal in this embodiment may specifically be a terminal such as a mobile phone, a tablet computer, and a digital reader, preferably a smart phone. The metal casing may be the rear casing or the middle frame of the mobile terminal. The metal shell is prepared by the manufacturing method of the metal shell provided in Example 2, so that the insulator filled in the gap has the same color and luster as the finished metal shell, visually presents a seamless appearance effect, and solves the problem of the current antenna The problem of inconsistency between the appearance of the partition strip and the metal shell saves the step of spraying the paint layer on the antenna partition strip, achieving the effects of reducing the process flow, improving production ef...

Abstract

The invention discloses a metal casing and a manufacture method thereof and a mobile terminal, and relates to the field of mobile terminals. The metal casing includes a slit, the slit is filled with an insulator, and the insulator comprises a plastic material, a first pigment and a second pigment; the first pigment is used to coloring the plastic material so that the color of the insulator is the same with that of a finished metal casing; and the second pigment is used to change luster of the plastic material, so that metal luster of the insulator is the same with that of the finished metal casing. According to the invention, the appearance of the finished metal casing is consistent with that of the insulator, the problem that the appearance of an antenna isolating strip is inconsistent with that of the metal casing at present is solved, a step of coating the antenna isolating strip with a paint layer is omitted, process flows are reduced, the production efficiency is improved, the metal feeling and of the whole mobile terminal is enhanced, and the beauty level of appearance is improved.

Description

technical field [0001] Embodiments of the present invention relate to mobile terminal technologies, and in particular, to a metal casing, a manufacturing method, and a mobile terminal. Background technique [0002] The antenna is an important part of the mobile terminal, and it is an important wireless device for transmitting and receiving communication signals when the mobile terminal communicates with the base station. When the mobile terminal transmits a communication signal, the antenna converts the electrical signal into an electromagnetic wave signal and sends it out; at the same time, it can timely convert the received electromagnetic wave signal into an electrical signal, and output it to the corresponding circuit inside the mobile terminal. [0003] With the improvement of users' requirements for the appearance and touch of mobile terminals, more and more mobile terminal shells are made of metal materials, that is, except for the front display screen, the sides and ...
