Embodiment Construction

[0017] see Figure 1 to Figure 3 , the housing of the electronic device of the present invention can be a computer case, and its preferred embodiment comprises a bottom plate 11 and two side plates 12 perpendicular to the bottom plate 11, a front plate 14 and a rear plate 16, the two side plates 12 are parallel to each other and perpendicular to the front panel 14 and the rear panel 16 .

[0018] The rear panel 16 includes a rectangular body 160 and folded edges 163 vertically bent along the peripheral edges of the body. Among the folded edges 163, the edges of two opposite folded edges 163 are bent at intervals to have roughly cylindrical shapes. Crimping 1631. Distributed on the body 160 is a PCI area 161 for fixing expansion cards, a slot 162 for fixing an I / O backplane (not shown), and a fan area fixed together with a fan (not shown). 165 and a power supply area 167.

[0019] The PCI area 161 is riveted with some anti-electromagnetic interference shrapnel (not shown), s...

Abstract

The invention relates to an electronic device shell which comprises a rear plate, wherein the rear plate comprises a body, the body comprises a fan region and is provided with a first reinforced rib, a second reinforced rib and a third reinforced rib; the first reinforced rib is convexly formed along the edge of the circumference of the fan region and approximately encircles into a rectangle; the second reinforced rib is convexly formed closely adjacent to one side of the fan region and approximately encircles into a rectangle; the second reinforced rib is positioned at one side of the first reinforced rib; and the third reinforced rib encircles the first reinforced rib and the second reinforced rib.

Description

technical field [0001] The invention relates to an electronic device casing, in particular to an electronic device casing capable of improving the structural strength of a computer rear board. Background technique [0002] With the rapid development of computers, people in today's society pay more and more attention to computers. Generally, the back panel of a computer case has five areas, including a power supply area, a rear panel sky area, a fan area, and a PCI (Peripheral Component Interconnect, peripheral component expansion) area and an I / O (Input / Output, input / output) backplane area. In order to ensure the structural strength of the back plate of the computer case, the thickness of the back plate of the existing case is usually 1.00 mm. However, as the price of raw materials continues to rise, the cost of computer cases also continues to rise. In order to save production costs, the industry uses boards smaller than 1.00mm to produce the rear boards of computer cases...
