Machining method of clearance area of shell, shell and mobile terminal

Abstract

The invention discloses a machining method of a clearance area of a shell. The method comprises the steps that the shell is provided, wherein the shell is made of signal shielding materials and provided with a preset area, and the preset area comprises a first surface and a second surface which are oppositely arranged; at least one support structure is machined on the first surface of the preset area; a laser cutting machine is aligned with the second surface of the preset area, a preset number of hair cracks are cut in the preset area, and the hair cracks are arranged at intervals in parallel; each hair crack is filled with materials which do not shield signals, so that the clearance area is obtained; the support structures are cut out. According to the machining method of the clearance area of the shell, the preset number of the hair cracks are cut in the shell through lasers, and the hair cracks are filled with the materials, so that the clearance area is formed, and the clearance area with a specific shape is obtained; meanwhile, due to the fact that the hair cracks are narrow, the proportion of the materials which do not shield the signals in the shell is decreased, and the appearance integrity of the shell is guaranteed. The invention further provides the shell and a mobile terminal.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a processing method for a clearance area of ​​a housing, the housing and a mobile terminal. Background technique [0002] With the development of technology and market demand, the demand for all-metal mobile phones is increasing. Although the all-metal mobile phone is beautiful, its metal shell will block the radio frequency signal of the antenna to a certain extent. [0003] In the prior art, a certain clearance area is generally processed by CNC machine tools on the back of the metal mobile phone for the passage of radio frequency signals. However, the inventor found that the clearance area is limited by the cutting tool or control mode of the CNC machine tool when processing the above process. It cannot process the headroom area of ​​a specific shape, or the area of ​​the headroom area is often large, which affects the overall sense of the mobile phone. Contents of the i...
