Problems solved by technology

However, for electronic devices with signal transceiving devices, a housing made entirely of metal will affect signal transceiving due to electromagnetic shielding.
Moreover, a single metal shell has a large weight, which is not conducive to the development of thinner and lighter electronic products
Although the plastic shell is light in weight, its thinning is also limited due to its low strength

Embodiment Construction

[0030] see figure 1 and figure 2 The case 10 of the electronic device in the preferred embodiment of the present invention takes a mobile phone back cover as an example, which includes a metal part 12 and a plastic part 14 combined with the metal part 12 .

[0031] The metal piece 12 is substantially rectangular, and includes a first portion 122 , a second portion 124 opposite to the first portion 122 , and a connection portion 126 between the first portion 122 and the second portion 124 . The first portion 122 is adjacent to one end of the metal member 12 , and the second portion 124 is adjacent to another opposite end of the metal member 12 .

[0032] The first portion 122 defines a plurality of first stepped holes 1221 . The distribution density of the first stepped holes 1221 on the metal piece 12 gradually decreases from the first portion 122 to the connecting portion 126, and the diameter of the first stepped holes 1221 gradually decreases from the first portion 122 t...

Abstract

The invention provides an electronic device shell which comprises a metal piece and a plastic piece, wherein the plastic piece is combined with the metal piece; a plurality of step holes are formed on at least one part of area of the metal piece; the metal piece and the plastic piece are integrally moulded in an insert moulding manner; and the metal piece is laminated on one surface of the plastic piece, and the step hole is filled with the plastic piece so that the metal piece and the plastic piece form a smooth appearance together. The invention also provides a manufacture method of the electronic device shell.

Description

technical field [0001] The invention relates to an electronic device casing and a manufacturing method thereof. Background technique [0002] The casing is one of the main components of electronic devices, and it is widely used in electronic devices such as telephones, calculators, and computers. [0003] Electronic device housings are generally made of metal or plastic, and metal housings are widely used in electronic devices due to their high strength and good electromagnetic shielding effect. However, for an electronic device with a signal transceiving device, a casing made entirely of metal will affect signal transceiving due to electromagnetic shielding. Moreover, a single metal casing has a large weight, which is not conducive to the development of thinner and lighter electronic products. Although the plastic casing is light in weight, its thinning is also limited due to its low strength. Contents of the invention [0004] In view of this, it is necessary to provi...
