Shell, manufacturing method of shell, and electronic device with shell

Abstract

A manufacturing method of a shell includes the following steps that a metal base body is provided, micro-fracture cutting is conducted on the metal base body so that the metal base body can be cut into at least one metal piece and at least one body part, two first side surfaces which are parallel are formed on each metal piece, and second side surfaces opposite to the metal pieces are formed on the body parts as well; surface processing is conducted on the metal pieces and the body parts where micro-fracture cutting is conducted, and a plurality of holes are formed in the first side surfaces and the second side surfaces; and the body parts and the metal pieces are placed in a mold in a butt joint manner, the width of gaps between the body parts, between the body parts and the adjacent metal pieces and between the adjacent metal pieces is 0.1-0.3 mm, non-conductor parts are contained in the gaps and are partly embedded in the holes, and therefore the body parts and the metal pieces are connected through the non-conductor parts. The invention further provides the shell manufactured through the manufacturing method, and an electronic device with the shell.

Description

technical field [0001] The invention relates to a casing, a manufacturing method of the casing and an electronic device using the casing. Background technique [0002] Electronic devices with thinner metal shells are favored by consumers, but the metal shells will shield the electronic signals of the antennas and reduce the radiation performance of the antennas. [0003] In the prior art, a slit is opened on the metal shell through computer numerical control (CNC), and then plastic parts are filled in the slit to ensure that the transmission of the antenna signal is not affected by the metal shell. However, the width of the gap made by CNC cutting is relatively large, which makes it difficult to achieve a good combination between the metal casing and the plastic part, resulting in the plastic part falling off the metal casing more easily, thereby reducing the service life of the electronic device. Furthermore, the plastic parts will occupy a large internal space of the elec...

Problems solved by technology

However, the width of the gap made by CNC cutting is relatively large, which makes it impossible to achieve a good combination between the metal casing and the plastic parts, causing the plastic parts to fall off the metal casing more easily, thereby reducing the service life of the electronic device

Furthermore, plastic parts will occupy a large internal space of the electronic device, which is not conducive to the development trend of thinner electronic devices
