Problems solved by technology

The punching process of the convex hull is actually a process of stretching the sheet to locally thin the sheet to enlarge the surface area, which makes it easy to break at the side wall of the convex hull after punching, which seriously affects the product yield and causes The cost has increased significantly

Embodiment Construction

[0018] see figure 1 A preferred embodiment of the electronic device 8 of the present invention includes a metal casing 20 and a plurality of electronic components 10 accommodated in the metal casing 20 .

[0019] In this embodiment, the maximum frequency of the electromagnetic waves generated by the electronic component 10 during operation does not exceed 2 GHz, that is, the minimum wavelength of the generated electromagnetic waves is not less than 150 mm.

[0020] The casing 20 includes a frame 30 and a cover 40 covering the frame 30 .

[0021] Several holes 31 are provided on the frame 30 . The diameter of each hole 31 is not greater than one-thirtieth of the minimum wavelength, that is, 5 mm, so as to prevent electromagnetic waves generated by the electronic components 10 from leaking out of the casing 20 . The hole 31 can assist the electronic device 8 to dissipate heat.

[0022] The cover plate 40 can be made of iron, and the iron cover plate can be processed by second...

Abstract

The invention relates to a metal meshed board. The metal meshed board comprises a meshed area, wherein the meshed area contains a plurality of adjacent hole units; each two adjacent hole units share an edge; each hole unit contains a punched hole and a plurality of edges around the hole; the centre line of each edge is a curve; and the meshed area can be drawn and deformed along any direction parallel to the meshed area on the condition that the thickness is not changed. The extending ability of the meshed area greatly makes up for the defect that the plate has poor extensibility, thus efficiently solving the fracture problem in the drawing process of the plate. The invention also relates to a preparation method of a cover plate and an electronic device.

Description

technical field [0001] The invention relates to a mesh design on a metal material. Background technique [0002] Electronic devices generally have metal housings. Convex designs are often required on metal housings. Convex hulls are usually stamped on flat sheets. The punching process of the convex hull is actually a process of stretching the sheet to locally thin the sheet to enlarge the surface area, which makes it easy to break at the side wall of the convex hull after punching, which seriously affects the product yield and causes The cost has increased significantly. Contents of the invention [0003] In view of the above, it is necessary to provide a metal mesh plate that can solve the fracture problem during the stretching process of the plate, a manufacturing method and a related product. [0004] A metal mesh plate, including a mesh area, the mesh area includes a plurality of hole units adjacent to each other, every two adjacent hole units share a lap, and each...
