Metal housing and manufacturing method thereof

Abstract

The invention discloses a metal housing and a manufacturing method thereof. According to the invention, a metal thin layer is deposited in an electrical connection contact area on a shell of the metalhousing, and the abrasion resistance and corrosion resistance of the metal thin layer are higher than that of a metal base material adopted by the shell, so that the metal thin layer is exposed at anelectrical connection contact in the actual using process, the high abrasion resistance and high corrosion resistance of the metal thin layer can avoid repeated friction between the electrical connection contact and a metal elastic piece on a mainboard of electrical equipment to generate particles, and thus the conductivity of the electrical connection contact is avoided from being affected by oxidation and accumulation of the particles. Compared with a mode of fixing a metal sheet on the electrical connection contact through laser welding, ultrasonic welding or screws in the prior art, the deposited metal thin layer in the embodiment of the invention is not limited by the space of an inner cavity of the shell and can be implemented on any sizes of electrical connection contacts, so thatthe embodiment of the invention can fundamentally solve a conductive problem of the electrical connection contact on the metal housing.

Description

technical field [0001] The invention relates to the technical field of electronic equipment manufacturing, in particular to a metal casing and a manufacturing method thereof. Background technique [0002] At present, most electronic devices use metal casings to use the metal casing as an antenna or a part of the antenna, thereby reducing the space occupied by the antenna, which is conducive to the miniaturization and ultra-thinning of electronic devices, and is more convenient for users to carry. . [0003] Figure 1A It is a schematic diagram of a partial structure of the inner cavity of a metal casing of an existing electronic device, Figure 1B It is a schematic diagram of a partial structure of a motherboard of an electronic device. refer to Figure 1A , there are usually more than a dozen electrical connection contacts in the inner cavity of the metal casing, including the areas marked by labels 111-115; correspondingly, refer to Figure 1B , the main board is provid...
