Problems solved by technology

[0003] However, since the metal shield needs to cover the outer surface of the device to be shielded, when it is assembled into the electronic device, the thickness of the electronic device will increase, which is contrary to the development needs of thinner and lighter electronic devices

Embodiment 1

[0044] Embodiment 1: split structure

[0045] In an exemplary embodiment, such as image 3 As shown, the plate-shaped body 31 and the hollow cylinder 5 can be manufactured separately, and then by connecting one end of the hollow cylinder 5 to the side of the plate-shaped body 31 close to the printed circuit board 1, the hollow cylinder can be formed. The side wall of the body 5 and the surface of the plate-shaped body 31 enclose a groove 33 (or called the raised portion 32 provided with the groove 33 ).

[0046]In this embodiment, by determining the thickness of the corresponding to-be-shielded device 2 in advance, and the distances that need to be kept between the to-be-shielded device 2 and the bottom surface and side wall of the groove 33, the requirements for each to-be-shielded device 2 can be respectively obtained. The hollow cylinder 5 is then connected to the plate body 5 to form a corresponding groove 33 . Wherein, the connection between the hollow cylinder 5 and th...

Embodiment 2

[0047] Embodiment 2: Integrated structure

[0048] In another exemplary embodiment, the metal shell 3 can be integrally formed; for example, the metal shell 3 required by the present disclosure can be directly obtained through die-casting, so that the plate-shaped body 31 is provided with a concave Several protrusions 32 of the groove 33.

[0049] Of course, the above-mentioned "die-casting" process is only an optional form, and it is obvious that the required metal shell 3 can also be processed in other ways, which is not limited in the present disclosure.

[0050] 2. The specifications of the protrusion 32 and the groove 33

[0051] As an exemplary embodiment, such as Figure 2B As shown, the bottom surface of the groove 33 is flush with the surface of the plate-shaped body 31, and the height of the raised portion 32 needs to be reasonably set to meet the requirements between the top surface of the device 2 to be shielded and the bottom surface of the groove 33. keep a di...

Abstract

The invention relates to electronic equipment and a metal casing thereof. The metal casing can replace an electromagnetic shielding can in the electronic equipment to reduce the thickness of the electronic equipment. The electronic equipment is internally provided with a PCB (Printed Circuit Board) adjacent to the metal casing, and the side, close to the metal casing, of the PCB is provided with devices to be shielded; the metal casing comprises a plate-shaped casing body, and projection portions formed in the side, close to the PCB, of the plate-shaped casing body in one to one correspondence with the devices to be shielded, and the end surface of each projection portion forms a groove inwardly; and the size and specification of each groove match those of the corresponding device to be shielded, so that when the metal casing and the PCB are assembled to the electronic equipment, each groove is electrically connected to the PCB, can accommodate the corresponding device to be shielded, and is separated from the accommodated device to be shielded for a preset interval.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular, to a metal case of an electronic device and the electronic device. Background technique [0002] In related technologies, it is necessary to add corresponding electromagnetic shielding covers to shielding devices such as CPU and radio frequency chips in electronic equipment, so as to meet electromagnetic radiation requirements and ensure normal operation of electronic equipment. [0003] However, since the metal shield needs to cover the outer surface of the device to be shielded, when it is assembled into the electronic device, the thickness of the electronic device will increase, which is contrary to the development requirements of thinner and lighter electronic devices. Contents of the invention [0004] The disclosure provides a metal casing of an electronic device and the electronic device to solve the deficiencies in the related art. [0005] According to th...
