Communication equipment metal shell

Abstract

The invention discloses a communication equipment metal shell, which comprises a metal substrate, more than one slit, a plastic support layer and a decorative layer, wherein the more than one slit runs through the metal substrate; the plastic support layer is formed on the inner surface of the metal substrate; the decorative layer is formed on the outer surface of the metal substrate; the communication equipment metal shell is characterized in that the widths of the slits on the outer surface of the metal substrate are 15-500microns; the widths of the slits on the inner surface of the metal substrate are 20-600microns; and the ratio of the widths of the slits on the inner surface of the metal substrate to those on the outer surface of the metal substrate is (1.05-1.5) to 1. The communication equipment metal shell which is relatively small in slit taper and beneficial to passing of an electromagnetic signal, and has an integrated effect in appearance can be provided.

Description

technical field

[0001] The invention relates to a metal casing of communication equipment. Background technique

[0002] With the development of metal processing technology, mobile communication devices such as mobile phones and tablet computers are increasingly inclined to use metal casings, especially large-area metal casings, but electromagnetic waves cannot penetrate metals. In order to achieve good electrical signal effects, metal casings are used. It is necessary to process single or multiple slits on the shell, and design the antenna at the slit.

[0003] The existing method of processing slits is mainly to use short-wavelength lasers such as green light to etch the metal substrate layer by layer. This method has low processing efficiency and cannot process thick slits due to the problem of depth of focus. The metal base material (up to 0.4mm), the processed product has low strength. In addition, this method requires repeated processing many times to cut through the...
