Abstract

The embodiment of the invention provides a metal shell, a fabrication method thereof and a mobile terminal. The metal shell comprises a back cover and an intermediate frame, wherein the back cover andthe intermediate frame are connected to form an inner cavity of the metal shell, at least one antenna slot is formed in a corresponding part on the back cover and/or the intermediate frame, glue grabbing structures are respectively arranged at parts, at two sides of the antenna slot, of an inner side surface of the intermediate frame, gear shaping grooves are formed in the glue grabbing structures, the antenna slot is filled with plastic, and the glue grabbing structures are coated with the plastic. In the metal shell disclosed by the embodiment of the invention, the glue grabbing capabilityof the glue grabbing structures are improved by the gear shaping grooves, the bonding capability of the metal shell and the plastic is effectively improved, so that the mobile terminal can be prevented from being abandoned due to separation of metal and the plastic during falling or maintenance and disassembly, and the brand quality and competiveness can be improved; and moreover, the gear shapinggrooves can be formed in protruding parts by a mode of gear shaping, the metal shell is not needed to be partitioned into multiple segments for drilling and injection molding after processing, the processing technology is simplified, and the processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic product processing, in particular to a metal casing, a preparation method thereof, and a mobile terminal. Background technique [0002] With the popularization of mobile terminals, people put forward higher requirements on the appearance of mobile terminals, requiring better experience in tactile and visual appearance, which prompts more and more manufacturers to use metal casings as the body of mobile terminals. [0003] In a mobile terminal using a metal casing as the body, in order to improve the radio frequency capability of the antenna, it is usually necessary to provide an antenna slot on the metal casing, and inject plastic into the antenna slot to ensure the integrity and structural strength of the body. In order to improve the bonding strength between the plastic and the metal casing, the metal casing is usually provided with a gripping structure. [0004] Such as figure 1 As shown, ...
