A metal shell of communication equipment and its preparation method and application

Abstract

Provided are a metal housing for a communication device, a preparation method therefor, and applications thereof. The preparation method for the metal housing comprises: 1) injecting plastic on the inner surface of a metal housing (1) to form a plastic layer (2) provided with at least one narrow gap; 2) forming a decorative layer (3) on the outer surface of the metal housing (1); 3) forming a protective layer on the outer surface of the decorative layer (3); 4) etching the metal housing (1) corresponding to the narrow gap from the inner surface of the metal housing (1), so as to enable the metal housing (1) at the position of the narrow gap to penetrate through; 5) forming a colloidal stuffed piece (4); and 6) removing the protective layer.

Description

technical field

[0001] The invention relates to the field of metal shells, in particular to a metal shell of a communication device and a preparation method and application thereof. Background technique

[0002] The mobile phone antenna is a device used to receive signals on the mobile phone. At present, most smart phones have built-in antennas, which requires that the back cover of the mobile phone cannot shield the signal. Plastic casing mobile phones do not have this problem. For the emerging popular metal casing mobile phones, how to solve the signal shielding problem is one of the keys to their design and manufacture.

[0003] At present, most metal mobile phones adopt the method of opening antenna slots and injection molding to solve the problem of signal shielding of the fuselage, such as the upper and lower antenna slots of HTCONE, and the side antenna slots of iPhone 5 / 5S. The above-mentioned prior art prevents signal shielding by filling the antenna slot with plas...
