Description

Technical Field

[0001] This invention relates to the field of server slide rail technology, specifically a server slide rail with a cable management rack. Background Technology

[0002] Servers in data centers are typically placed in racks. The front and rear ends of the server rails are connected to the front and rear ends of the rack via mounting brackets. The server chassis is installed in the rack via the server rails, so the chassis can be pulled out or retracted from the rack via the rails.

[0003] Server rails typically include a cable management rack, rail assemblies on both sides, and mounting brackets on both sides. The rail assemblies are generally divided into two-section (including inner rail, outer rail, and ball bearing bracket) or three-section (including inner rail, middle rail, outer rail, and ball bearing bracket). The inner rail of the rail assembly is used to mount the server chassis, while the mounting bracket is used to connect to the outer rail and provide support for the rail assembly. The cable management rack is used to store server cables and is generally located at the rear of the rail assembly. It usually includes two foldable cable management arms and a support plate for support. One of the cable management arms is connected to the rear of the inner rail, so that when the rail assembly is opened, the cable management arm moves together with the inner rail, allowing the cables to move with the server chassis. The support plate of the cable management rack is connected to the rear of the outer rail of the two side rail assemblies through connectors at both ends, thereby providing support for the cable management rack.

[0004] During installation, the mounting bracket is usually fixed to the cabinet, and then the slide rails are installed on the brackets. The chassis is installed on the inner rails, and the cable management rack is connected to the inner and outer rails of one slide rail assembly and the outer rail of the other slide rail assembly via connectors. Traditional slide rail assemblies have fixed positions, so slide rail assemblies on the left must be connected to the left mounting bracket, and slide rail assemblies on the right must be connected to the right mounting bracket. This requires distinguishing the slide rail assemblies during installation, which is inconvenient. Summary of the Invention

[0005] To address the issue that traditional server slide rail assemblies require distinguishing between left and right, this invention provides a server slide rail with a cable management rack. During installation, it is not necessary to distinguish between the left and right sides of the slide rail assembly, making installation and use easier.

[0006] The technical solution is as follows: a server slide rail with cable management rack, comprising slide rail assemblies on both sides, mounting brackets on both sides, and cable management racks. The slide rail assemblies on both sides each include an inner rail and an outer rail. The inner rail has mounting holes for connecting to a server chassis, and the outer rail has assembly holes for connecting to the mounting brackets. The rear ends of the inner rail and the outer rail are respectively provided with connectors for connecting to the cable management racks. The mounting holes are symmetrically distributed with the central axis of the corresponding side slide rail assembly as the axis of symmetry. The assembly holes are symmetrically distributed with the central axis of the corresponding side slide rail assembly as the axis of symmetry. The connectors include a main connector and a spare connector, which are symmetrically distributed with the central axis of the corresponding side slide rail assembly as the axis of symmetry.

[0007] Its further features are:

[0008] The slide rail assembly also includes a self-locking mechanism, which includes a locking plate one, a locking plate two, a compression spring, and a locking block. When the slide rail assembly is a three-section slide rail, the locking block is located at the front end of the middle rail; when the slide rail assembly is a two-section slide rail, the locking block is located at the front end of the outer rail. The rear end of the locking plate one is rotatably connected to the inner rail. The bottom / top of the locking plate one has a locking groove that mates with the locking block. The front and rear walls of the locking groove are vertical or inclined inward. The bottom / top of the locking plate one is also provided with a locking groove in front of the locking groove. The inclined guide clearance surface allows the locking block to be positioned on the guide clearance surface and the moving path of the locking groove when the slide rail assembly is open and the locking block is not in contact with the locking piece one. The front end of the locking piece one is connected to the inclined limiting groove two on the locking piece two via a connecting pin one. The locking piece one is also connected to the inner rail via a compression spring, which is used to press the locking piece down / up. The locking piece two includes the limiting groove two located at the rear, an extended part in the middle, and an unlocking part at the front. The locking piece two is slidably connected to the inner rail.

[0009] When the locking block is located in the locking groove and the slide rail assembly is a two-section slide rail, the unlocking part is located in front of the outer rail; when the locking block is located in the locking groove and the slide rail assembly is a three-section slide rail, the unlocking part is located in front of the middle rail.

[0010] A reinforcing plate is also installed at the front end of the outer rail. The shape of the reinforcing plate corresponds to the shape of the outer rail, and the reinforcing plate is set to fit the upper and lower sides of the front end of the outer rail.

[0011] The cable management rack includes a cable routing arm 1, a cable routing arm 2, an adapter, a connector 1, a connector 2, a connector 3, and a support plate. One end of the cable routing arm 1 is rotatably connected to the connector 1, and the other end is rotatably connected to one end of the adapter. The other end of the adapter is rotatably connected to one end of the cable routing arm 2, and the other end of the cable routing arm 2 is rotatably connected to the connector 2. One end of the support plate is connected to the bottom of the connector 2, and the other end is connected to the connector 3. The connector 1 and the connector 2 are respectively connected to the inner rail and outer rail of one side of the slide rail assembly, and the connector 3 is connected to the outer rail of the other side of the slide rail assembly. The connector 1, the connector 2, and the connector 3 each include a connecting end and an extension end. The connecting end is used to connect to the slide rail assembly. The connector 1 also includes an extension mechanism, which includes an extension plate. One end of the extension plate is rotatably connected to the cable routing arm 1, and the other end is connected to the middle of the extension end via a tension spring. The extension plate is slidably connected to the extension end.

[0012] A groove is provided on the extended end of connector one. A guide post is connected to the extended plate. The guide post passes through the groove and is connected to a limiting block. The width of the limiting block is greater than the width of the groove. A telescopic mechanism is also installed at the end of cable routing arm one and cable routing arm two away from the adapter. The telescopic mechanism includes a telescopic plate. Cable routing arm one and cable routing arm two are respectively connected to the telescopic plate by a tension spring. The telescopic plate is rotatably connected to the extended plate of connector one / the extended end of connector two. A groove is provided on cable routing arm one and cable routing arm two. A guide post is connected to the telescopic plate. The guide post passes through the groove and is connected to a limiting block. The width of the limiting block is greater than the width of the groove.

[0013] The main connector and the spare connector are vertically arranged connecting hooks that bend towards each other. The rear end of the connecting hook has an inclined guide surface one, and the front end of the connecting hook has a vertical snap-fit ​​surface one. The connecting end includes an unlocking hole, a snap-fit ​​component, and a torsion spring. The snap-fit ​​component is rotatably connected to connector one / connector two / connector three through the torsion spring. The snap-fit ​​component includes a hook-shaped snap-fit ​​end and an unlocking end. The front end of the snap-fit ​​end is a guide surface two that mates with guide surface one, and the rear end of the snap-fit ​​end is a snap-fit ​​surface two that mates with snap-fit ​​surface one. A portion of the unlocking end overlaps with a portion of the unlocking hole.

[0014] The mounting bracket includes a front bracket and a rear bracket. The front bracket is used to connect with the front bracket of the cabinet, and the rear bracket is used to connect with the rear bracket of the cabinet. The front bracket and the rear bracket each include a guide positioning mechanism, which is used to extend into the mounting hole on the cabinet bracket. The guide positioning mechanism includes a base plate, a mounting plate, a guide post, a guide sleeve, and a spring. The base plate and the mounting plate form a mounting cavity. One end of the guide post is connected to the wall of one end of the mounting cavity, and the other end of the guide post passes through the wall of the other end of the mounting cavity through a through hole and extends out of the mounting cavity. The guide sleeve passes through the wall of the mounting cavity through the through hole and is sleeved on the guide post. The spring is provided between the end face of the guide sleeve located in the mounting cavity and the wall of one end of the mounting cavity.

[0015] The guide sleeve has a flange one at one end located in the mounting cavity, and the diameter of the flange one is larger than the diameter of the through hole. The guide sleeve has a flange two at the other end, and the diameter of the flange two is larger than the diameter of the through hole.

[0016] The base plate is L-shaped and includes a mounting part one and a connecting part one. The mounting plate is Z-shaped and includes an enclosing part, a mounting part two, and a connecting part two. The connecting part one, mounting part one, enclosing part, and mounting part two sequentially enclose to form the mounting cavity. The guide post is connected to the mounting part two. The through hole is opened on the mounting part one. The connecting part two is connected to the connecting part one.

[0017] With this structure, the mounting holes for installing server chassis and the assembly holes for connecting mounting brackets are symmetrically distributed around the central axis of the slide rail assembly. Even if the slide rail assembly is rotated 180 degrees from one side and installed on the other side, it can still be used normally for installing server chassis and connecting mounting brackets. At the same time, since both the inner and outer rails of the slide rail assembly are equipped with connectors, each connector includes main and backup connectors symmetrically distributed along the central axis, even if the slide rail assembly is rotated 180 degrees from one side and installed on the other side, it can still be used normally for installing cable management racks. Thus, it is not necessary to distinguish between the left and right sides of a pair of slide rail assemblies, which is convenient for installation and use. Attached Figure Description

[0033] like Figure 1 , Figure 2 , Figure 6 The server slide rail with cable management rack shown (in this embodiment, "front" refers to the forward direction of the inner rail when the slide rail is opened) includes slide rail assemblies a (which are three-section slide rail assemblies) located on both sides, mounting brackets 5 and cable management racks 7 located on both sides. The slide rail assemblies a on both sides respectively include an inner rail 1 and an outer rail 2, and a middle rail 3 located on the inner rail 1 and the outer rail 2 and interlocking with them. Figure 2 The middle 4 is a ball bearing cage, combined with Figure 3 ( Figure 3 The inner rail is Figure 2 The inner rail 1 (on the back side) has mounting holes 101 for connecting to the server chassis, and the outer rail 2 has assembly holes 201 for connecting to the mounting bracket 5. The mounting bracket 5 is connected to the outer rail 2 via a pin located in the assembly hole 201. Figure 4The inner rail 1 and the outer rail 2 are respectively provided with connectors 6 for connecting to the cable management rack 7. The mounting holes 101 are symmetrically distributed with the central axis of the slide rail assembly as the axis of symmetry. The assembly holes 201 are symmetrically distributed with the central axis of the slide rail assembly as the axis of symmetry. The connectors 6 include a main connector 601 and a spare connector 602. The main connector 601 and the spare connector 602 are symmetrically distributed with the central axis of the slide rail assembly as the axis of symmetry. After the slide rail assembly is flipped, the cable management rack can be connected to the spare connector 602.

[0034] Specifically, the mounting hole 101 includes an insertion hole 1011 for the head of the mounting pin of the server chassis to extend into, and an oblong hole 1012 communicating with the insertion hole 1011 for the rod of the mounting pin of the server chassis to pass through. The head of the mounting pin is larger than the rod and its cross-section is T-shaped. When installing the chassis, the head is first inserted into the insertion hole, and then the chassis is moved forward so that the rod moves into the oblong hole 1012. In this way, the chassis can complete the connection with the inner rail.

[0035] The main connector 601 and the spare connector 602 are hook-shaped, and their hook-shaped parts are as follows: Figure 4 The relative arrangement shown is for connection with the hook-shaped connector of the cable management frame 7.

[0036] Combination Figure 3 , Figure 5 The slide rail assembly a also includes a self-locking mechanism, which includes a locking plate 102, a locking plate 103, a compression spring 104, and a locking block 301; when the slide rail assembly is a three-section slide rail, such as Figure 5As shown, the locking block 301 is located at the front end of the middle rail 3, while when the slide rail assembly is a two-section slide rail, the locking block is located at the front end of the outer rail. The rear end of the locking piece 102 is rotatably connected to the inner rail 1 via a pin. The bottom of the locking piece 102 (or the top if used by flipping it 180 degrees) is provided with a locking groove 105 that mates with the locking block. The front and rear walls of the locking groove 105 are either vertical or inclined inward (this ensures that when the locking block is in the locking groove, it will not disengage from the locking groove when subjected to forward or backward forces). The bottom of the locking piece 102 (or the top if used by flipping it 180 degrees) in front of the locking groove 105 is also provided with an inclined guide avoidance surface 106. This way, when the inner rail is pulled out, the guide avoidance surface 106 will contact the protruding locking block, causing the locking piece 102 to be inclined again. Under the action of rotation upward, when the slide rail assembly is open and the locking block 301 is not in contact with the locking piece 102, the locking block 301 is located on the moving path of the guide clearance surface 106 and the locking groove 105. The front end of the locking piece 102 is connected to the inclined limiting groove 108 on the locking piece 2 103 through the connecting pin 107. The locking piece 102 is also connected to the inner rail 1 through the compression spring 104. The compression spring 104 is used to press the locking piece 102 down (or up if it is used by flipping 180 degrees). The locking piece 2 103 includes the limiting groove 2 108 at the rear, the extended part 1031 in the middle, and the unlocking part 1032 at the front. The locking piece 2 103 is slidably connected to the inner rail 1.

[0037] When the server chassis is pulled out, the inner rail moves forward with the chassis until the guide relief surface of locking plate one contacts the locking block. Under continuous pulling force, because the guide relief surface is inclined, it will give locking plate one an upward force to lift it up until the locking block enters the locking groove. Locking plate one then falls under the action of the compression spring, and the locking block will be stuck in the locking groove and cannot be automatically disengaged, thus locking the inner rail and preventing it from retracting or being pulled out further. Only by pulling locking plate two forward, under the action of the inclined limiting groove two, can locking plate one be rotated again. At this time, pushing the inner rail can unlock it. Because of the use of locking plate two, the force applied during unlocking is parallel to the central axis of the slide rail assembly. This way, even after flipping the slide rail assembly, the unlocking method remains unchanged, so there is no need to distinguish between left and right.

[0038] Combination Figure 6 When the locking block 301 is located in the locking groove 105 and the slide rail assembly is a two-section slide rail, the unlocking part 1032 is located in front of the outer rail 2; when the locking block 301 is located in the locking groove 105 and the slide rail assembly is a three-section slide rail, the unlocking part 1032 is located in front of the middle rail 3; this extension of the unlocking part ensures that the unlocking part of the locking piece 2 of the inner rail is exposed in the locked state, making it convenient to use.

[0039] In addition, combined Figure 7The outer rail 2 is also equipped with a reinforcing plate 8 (connected to the mounting bracket by rivets). The shape of the reinforcing plate 8 corresponds to the shape of the outer rail 2. The reinforcing plate 8 is set to fit the upper and lower sides of the front end of the outer rail 2. By wrapping the outer rail with the reinforcing plate, it can ensure that the rail does not deform, prevent the middle rail from falling out, and reduce shaking when used in overtravel slide rail.

[0040] Combination Figure 1 , Figure 8 , Figure 9 The cable management rack 7 includes a first cable management arm 71, a second cable management arm 72, an adapter 73, a first connector 74, a second connector 75, a third connector 76, and a support plate 77. One end of the first cable management arm 71 is rotatably connected to the first connector 74 via a component such as a pin, and the other end is rotatably connected to one end of the adapter 73. The other end of the adapter 73 is rotatably connected to one end of the second cable management arm 72, and the other end of the second cable management arm 72 is rotatably connected to the second connector 75. One end of the support plate 77 is connected to the bottom of the second connector 75, and the other end is connected to the third connector 76. In this way, the support plate can support the cable arm, and the support plate is fixed by the second and third joints connected to the outer rail of the slide rail. The first joint 74, the second joint 75, and the third joint 76 respectively include a connecting end 78 and an extension end 79. The connecting end 78 is used to connect with the slide rail. The first joint 74 also includes an extension mechanism, which includes an extension plate 710. One end of the extension plate 710 is rotatably connected to the cable arm 71, and the other end is connected to the middle of the extension end through a tension spring 711. The extension plate 710 is slidably connected to the extension end 79.

[0041] The extension end can increase the length of the connector, and its parallel arrangement to the slide rail also increases the total stroke of the device, allowing the server length requirements to be met without excessively lengthening the slide rail and affecting its strength. Additionally, an extension mechanism at the connector allows for further stretching, enabling the cable management rack to meet the long-stroke slide rail length requirements, achieving an overtravel of approximately 910mm.

[0042] In addition, combined Figure 10 A groove 712 is provided on the extension end 79 of the connector 74. The extension plate 710 is connected to a guide post 713. The guide post 713 passes through the groove 712 and is connected to the limiting block 714. The width of the limiting block 714 is greater than the width of the groove 712, which facilitates the guidance of the extension plate 710.

[0043] Combination Figure 9The ends of cable routing arms 71 and 72 furthest from the adapter 73 are also equipped with telescopic mechanisms (taking cable routing arm 71 as an example in the figure). The telescopic mechanism includes a telescopic plate 715. Cable routing arms 71 and 72 are respectively connected to the telescopic plate 715 via tension springs 711. The telescopic plate 715 is rotatably connected to the extension plate 710 of connector 74 and the extension end 79 of connector 75. Thus, based on the extension mechanism, the telescopic mechanism can further increase the length of the cable management rack.

[0044] To facilitate the guiding and positioning of the telescopic mechanism, the cable routing arm 71 and the cable routing arm 72 are respectively provided with a sliding groove 712. The telescopic plate 15 is connected to a guide post, which passes through the sliding groove 712 and is connected to the limiting block 714. The width of the limiting block 714 is greater than the width of the sliding groove 712.

[0045] Combination Figure 4 , Figure 11 , Figure 12 The main connector 601 and the spare connector 602 are vertically arranged connecting hooks that bend towards each other. The rear end of the connecting hook has an inclined guide surface 6001, and the front end of the connecting hook is a vertical snap-fit ​​surface 6002. The connecting end 78 includes an unlocking hole 781, a snap-fit ​​member 782, and a torsion spring 783. The snap-fit ​​member 782 is rotatably connected to the connector 74 / connector 75 / connector 76 through the torsion spring 783. The snap-fit ​​member 782 includes a hook-shaped snap-fit ​​end 784 and an unlocking end 785. The front end of the snap-fit ​​end 784 is a guide surface 786 that mates with the guide surface 6001, and the rear end of the snap-fit ​​end 784 is a vertical or inwardly inclined snap-fit ​​surface 787 that mates with the snap-fit ​​surface 6002. A part of the unlocking end 785 overlaps with a part of the unlocking hole 781. With the above design, when the cable management rack is installed on the slide rail assembly, when the cable management rack is pushed and the guide surface 786 contacts the guide surface 6001, due to its inclined surface, the snap-fit ​​part 782 can rotate under the pushing force. At this time, the snap-fit ​​end 784 passes over the connector and enters the snap-fit ​​groove 6003 between the main connector 601 and the spare connector 602. In this way, the installation of the cable management rack can be completed. Since the snap-fit ​​surfaces 1 and 2 are vertical, it can be ensured that the snap-fit ​​end cannot be automatically pulled out. Only by inserting a finger into the unlocking hole 781 and turning the unlocking end 785 to make the snap-fit ​​part rotate and then pull out the connector.

[0046] Regarding mounting bracket 5, in conjunction with... Figure 1 , Figure 13The mounting bracket 5 includes a front bracket 51 and a rear bracket 52. The front bracket is used to connect with the front bracket of the cabinet, and the rear bracket is used to connect with the rear bracket of the cabinet. Both the front and rear brackets include a guide positioning mechanism. Taking the rear bracket as an example, the guide positioning mechanism is used to extend into the mounting holes on the cabinet bracket. The guide positioning mechanism includes a base plate 521, a mounting plate 522, a guide post 523, a guide sleeve 524, and a spring 525. The base plate 521 and the mounting plate 522 enclose a mounting cavity. One end of the guide post 523 is connected to the wall of one end of the mounting cavity. The other end of guide sleeve 523 passes through the through hole, penetrating the wall of the other end of the mounting cavity and extending out of the mounting cavity. Guide sleeve 524 passes through the through hole, penetrating the wall of the mounting cavity, and is fitted onto guide post 523. A spring 525 is provided between the end face of guide sleeve 524 and the wall of one end of the mounting cavity. This design allows the guide sleeve and guide post to slide relative to each other, making it suitable for different opening sizes on the rack bracket. Larger holes are positioned by the guide sleeve, while smaller holes are positioned by pushing the guide sleeve inward and relying on the guide post. The spring allows the guide sleeve to rebound. Specifically, combined with… Figure 15 The base plate 521 is L-shaped and includes a mounting part 5212 and a connecting part 5211. The mounting plate 522 is Z-shaped and includes an enclosure part 5221, a second mounting part 5222, and a second connecting part 5223. The first connecting part 5211, the first mounting part 5212, the enclosure part 5221, and the second mounting part 5222 sequentially enclose to form a mounting cavity 526. The guide post 523 is connected to the second mounting part 5222. A through hole 527 is formed on the first mounting part 5212. The second connecting part 5223 is connected to the first connecting part 5211 by rivets. This design is easier to install than the traditional C-shaped base plate and L-shaped mounting plate. During installation, it is only necessary to push the mounting plate so that its enclosure part contacts the first mounting part.

[0047] In addition, combined Figure 14 The guide sleeve 524 has a flange 5241 at one end located in the mounting cavity, and the diameter of the flange 5241 is larger than the diameter of the through hole. The guide sleeve 524 has a flange 5242 at the other end, and the diameter of the flange 5242 is larger than the diameter of the through hole. In this way, the flange can limit the guide sleeve.

[0048] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
