Description

Technical Field

[0001] This utility model relates to the technical field of server chassis, specifically to a rear shell mechanism of a pull-out chassis. Background Technology

[0002] Existing server chassis, which need to be stacked within the server rack, are generally designed as pull-out chassis. During the pulling-out process, the connecting devices on the shelves are moved, causing the connecting cables to move as well. The existing pull-out chassis do not consider the movement path of the connecting cables in their design, resulting in the connecting cables being stuck or completely exposed on the outside of the back shell when the shelves are pulled out. This leads to a large number of connecting cables remaining on the outside of the back shell, occupying space for adjacent servers. Therefore, there is an urgent need to develop a back shell mechanism that can temporarily store the connecting cables, thereby making the server chassis layout neat and aesthetically pleasing, and ensuring that the shelf pulling is reliable and smooth. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a rear shell mechanism for a pull-out chassis, which buffers excess connecting cables within the rear protruding cavity, resulting in a neat and aesthetically pleasing server room after assembly.

[0004] A rear shell mechanism for a pull-out chassis, located at the rear end of the chassis body, characterized in that it comprises: One rear upright board; And two rear convex cavities, each set of rear convex cavities includes a C-shaped surrounding plate, a top plate, and a bottom plate. The C-shaped surrounding plate is a bent sheet metal part formed by combining two side plates and a rear plate. The top plate and the bottom plate are respectively formed with bent connecting edges on both sides. The top plate is fixedly installed at the upper end of the C-shaped surrounding plate, and the bottom plate is fixedly installed at the lower end of the C-shaped surrounding plate. The rear upright plate has rectangular clearance holes on both sides corresponding to the width direction. The C-shaped side panels of the rear convex cavity have side protrusions to form sheet metal connecting edges. The rear convex cavity is covered by the rectangular clearance holes and fixed to the corresponding outer side of the rectangular clearance holes through the sheet metal connecting edges.

[0005] Its further features are: The inner side panel of the C-shaped enclosure has at least two first inlet / outlet holes arranged from top to bottom, which allow the connecting wires to connect the chassis and the outside through the first inlet / outlet holes; The top plate is provided with a second inlet / outlet hole, through which the connecting cable connects the chassis and the outside. The base plate is a closed structure, which ensures that no entry or exit line will detach from the rear convex cavity due to gravity; The top edge and the edges of both sides of the rectangular clearance hole are respectively welded with reinforcing ribs. The two sides of the C-shaped enclosure are fixed to the corresponding positions of the rear upright plate by fasteners. The reinforcing ribs ensure the stable and reliable assembly of the entire rear convex cavity and ensure that no deformation occurs. The inner side panel of the C-shaped enclosure has three sets of fastener positioning holes arranged from top to bottom on the sheet metal connection edge, and the outer side panel of the C-shaped enclosure has two sets of fastener positioning holes arranged from top to bottom on the sheet metal connection edge. This results in a different number of fasteners on each side, which facilitates error prevention and allows for quick and reliable assembly.

[0006] With the structure of this utility model, a rear-protruding cavity is provided on both sides of the width direction of the rear upright plate, so that the excess connecting wires are placed in the rear-protruding cavity after assembly. This makes the excess connecting wires of the pull-out chassis buffered in the rear-protruding cavity, resulting in a neat and beautiful server room after the server chassis is assembled.

[0008] A rear shell mechanism for a pull-out chassis, located at the rear end of the chassis body, see... Figures 1-3 It includes: a rear upright plate 10 and two rear convex cavities 20; Each set of rear convex cavities 20 includes a C-shaped surrounding plate 30, a top plate 40, and a bottom plate 50. The C-shaped surrounding plate 30 is formed by combining an inner side plate 31, a rear plate 32, and an outer side plate 33 to form a bent sheet metal part. The top plate 40 and the bottom plate 50 are respectively formed with bent connecting edges 1 on both sides. The top plate 40 is fixedly installed at the upper end of the C-shaped surrounding plate 30, and the bottom plate 50 is fixedly installed at the lower end of the C-shaped surrounding plate 30. Rectangular clearance holes 11 are provided on both sides of the rear upright plate 10 corresponding to the width direction. The two side plates of the C-shaped enclosure 30 of the rear convex cavity 20 are respectively convex to form sheet metal connecting edges 2. The rear convex cavity 20 is covered by the rectangular clearance holes 11 and fixed to the corresponding outer side of the rectangular clearance holes 11 through the sheet metal connecting edges 2.

[0009] In a specific embodiment, three first inlet / outlet holes 3 are arranged from top to bottom on the inner side plate 31 of the C-shaped enclosure 30, which allows the connecting wire to connect the chassis and the outside through the first inlet / outlet holes 3; A second inlet / outlet hole 4 is provided on the top plate 40, which allows the connecting cable to connect the chassis and the outside through the second inlet / outlet hole 4; The base plate 50 is a closed structure, which ensures that no entry or exit line will be detached from the rear convex cavity 20 due to gravity.

[0010] In a specific embodiment, reinforcing ribs 5 are welded to the top edge and the edges of both sides of the rectangular clearance hole 11. The two sides of the C-shaped enclosure 30 are fixed to the corresponding positions of the rear upright plate 10 by fasteners. The reinforcing ribs 5 ensure the stable and reliable assembly of the entire rear convex cavity 20 and ensure that no deformation occurs.

[0011] In a specific embodiment, the sheet metal connecting edge 2 of the inner side plate 31 of the C-shaped enclosure 30 is arranged with three sets of fastener positioning holes 6 from top to bottom, and the sheet metal connecting edge 2 of the outer side plate 33 of the C-shaped enclosure 30 is arranged with two sets of fastener positioning holes 6 from top to bottom. This makes the number of fasteners on both sides different, which facilitates error prevention and makes assembly quick and reliable.

[0012] The principle is as follows: A rear-protruding cavity is provided on both sides of the width direction of the rear panel, so that the excess connecting wires are placed in the rear-protruding cavity after assembly. This makes the excess connecting wires of the pull-out chassis buffered in the rear-protruding cavity, which makes the entire computer room neat and beautiful after the server chassis is assembled.
