Shell processing method, shell and mobile terminal

Abstract

The invention discloses a processing method for a casing, which includes: providing a casing, the casing is made of a signal shielding material; removing a material of a first preset thickness of the casing along a preset track on a first surface of the casing processing the antenna slot; filling the antenna slot with non-signal shielding material; removing a material with a second preset thickness on the second surface of the casing, so that the antenna slot penetrates the casing. The processing method of the housing provided by the embodiment of the present invention removes the first preset thickness of the housing along the preset trajectory to open an antenna slot that does not penetrate the housing, that is, the position of the antenna slot of the housing remains The thickness of the antenna slot provides good strength, so that when the antenna slot is filled with non-signal shielding materials, it has better strength support and will not cause deformation of the antenna slot due to excessive pressure, thereby improving the appearance of the housing. . The invention also provides a casing 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 shell, the shell 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 antenna seams were processed by CNC machine tools, and then nano injection molding was performed. Due to the high injection pressure during injection molding, the antenna slit is easily deformed due to extrusion, resulting in uneven width of the antenna slit and affecting the overall appearance of the housing.

[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 antenna seams were processed by CNC machine tools, and then nano injection molding was performed. Due to the high injection pressure during injection molding, the antenna gap is easily deformed due to extrusion, resulting in uneven width of the antenna gap, which affects the overall appearance of the housing
