Therefore, in the embodiment of the present invention, a printing layer 5 is provided on the outer surface of the insulating layer 4 to change the appearance of the insulating layer 4 .

It can be understood that it is difficult to match the color of the insulating layer 4 with the metal by adjusting the color of the insulating material, but it is much easier to match the color of the ink with the metal. Moreover, the printing layer 5 can be formed into different styles according to different requirements. In this way, the same color as the metal shell can be used, and the insulating layer 4 and the metal can be made to have the same color to improve the overall appearance of the metal shell. You can also choose other colors to decorate to beautify the appearance of the metal case.
