Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a compact rail-mounted network switch. Background Technology

[0002] In modern network communication systems, such as data centers and enterprise core computer rooms, standard racks (such as 19-inch standard racks) are typically used to centrally install and manage various network devices. As core network switching equipment, the number and performance of rail-mounted switches directly determine the carrying capacity and scalability of the entire rack and even the entire network.

[0003] Currently, the physical dimensions of mainstream DIN rail switches on the market are mainly determined by three dimensions: width, depth, and height. In actual deployments, to meet the application requirements of high-density port access and high-bandwidth data exchange, it is often necessary to install multiple such switches side by side in a standard rack.

[0004] However, existing DIN rail switches generally suffer from a significant design flaw: their excessive width results in a single switch occupying too much horizontal space (U-width) within the rack. When attempting to install the desired number of switches within a standard rack with limited width, this becomes impossible because the cumulative width of the switches exceeds the available rack width. This problem directly leads to the following adverse consequences: First, it limits the device installation density within a single rack, failing to maximize the use of expensive rack space and reducing space utilization. Second, it forces system designers to use more racks to accommodate the planned number of switches, increasing the data center footprint, power consumption, and overall construction and maintenance costs. Finally, because the predetermined number of devices cannot be installed, the expected port density and switching performance of the entire network system are forced to decrease, failing to meet the intended application requirements.

The bottom shell is used to install and fix the switch motherboard. The top cover is used to interlock with the bottom shell to form a cavity for accommodating the switch motherboard. The rail clips are detachably installed on the rear side of the bottom shell and are used to install the entire switch vertically on the horizontal rails of a standard cabinet. The maximum length of the switch is less than or equal to the available installation width of a single installation unit in a standard 19-inch cabinet, allowing multiple switches to be installed side-by-side densely within the standard cabinet.

[0017] like Figure 1 As shown, this utility model discloses a compact rail-mounted network switch, including an upper cover 1, a bottom shell 2, a switch motherboard 3, and rail clips 4. The bottom shell 2 is used to install and fix the switch motherboard 3; the upper cover 1 is used to interlock with the bottom shell 2 to form a cavity for accommodating the switch motherboard 3; the rail clips 4 are detachably installed on the rear side of the bottom shell 2 and are used to install the entire switch vertically on the horizontal rails of a standard cabinet; wherein, the maximum length of the switch as a whole is less than or equal to the available installation width of a mounting unit (1U) in a standard 19-inch cabinet, so that multiple switches can be installed side by side densely in the standard cabinet.

[0018] The bottom of the bottom shell 2 is provided with a plurality of studs 8 for supporting and positioning the switch motherboard 3. The studs 8 are provided with threaded holes for fastening the switch motherboard 3 with screws.

[0019] The bottom shell 2 is composed of a bottom plate 20 and a left baffle 21, a right baffle 22 and a rear baffle 23 extending upward from the left, right and rear edges of the bottom plate 20.

[0020] The top cover 1 includes a top plate 10 and a front panel 11 extending downward from the front edge of the top plate 10. The front panel 11 has through holes 12 corresponding to the interfaces of the switch motherboard 3.

[0021] The lower edge of the front panel 21 is bent inward horizontally to form a first mounting edge 13 for overlapping and fixing to the front edge of the bottom plate 20 of the bottom shell 2.

[0022] A first mounting hole 14 is provided on the first mounting edge 13, and a first threaded hole 24 is provided at the corresponding position on the front edge of the bottom plate 20 of the bottom shell 2. By screwing the screw through the first mounting hole 14 and into the first threaded hole 24, the front part of the top cover 1 is fixed to the bottom shell 2.

[0023] The upper edges of the left baffle 21, the right baffle 22 and the rear baffle 23 are bent inward horizontally to form a second mounting edge 25, a third mounting edge 26 and a fourth mounting edge 27 for overlapping and fixing the top plate 10.

[0024] The second mounting edge 25, the third mounting edge 26, and the fourth mounting edge 27 are respectively provided with second mounting holes 29, and the edge of the top plate 10 is provided with a corresponding second threaded hole 15. By screwing the screw through the second threaded hole 15 into the second mounting hole 29, the top plate 10 is fixed to the bottom shell 2.

[0025] The rear baffle 23 is provided with a first threaded hole, and the guide rail buckle 4 is provided with a second threaded hole. The guide rail buckle 4 is installed with the network switch as a whole by screws, the first threaded hole, and the second threaded hole.

[0026] The compact rail-mounted network switch disclosed in this utility model is an 8-port switch with a small width. The switch motherboard 3 is an 8-port switch motherboard, and its casing is described as follows: First, the 8-port switch motherboard is fixed to the bottom shell 2. The bottom shell 2 has four press-fit studs 8 to support and fix the 8-port switch motherboard. Then, the top cover 1 is closed to the bottom shell 2 for assembly. Next, the guide rail clips 4 are fixed to the bottom shell 2. There are two second threaded holes on the back of the bottom shell 2 for fixing the guide rail clips 4. The assembly is thus completed, which is simple and convenient. In the application scenario, the large cabinet is equipped with guide rails. The guide rail clips on the back of the switch are fastened to the guide rails to complete the installation and fixation. Due to the small width of the switch, it saves more space when installed inside a large cabinet, thus meeting the application scenarios that require the installation of a certain number of switches.

[0027] In typical applications, a certain number of switches are needed to meet application requirements within a large server rack. However, most switches are too wide to fit within the rack. This invention discloses a switch with a smaller width, requiring less space within a large server rack. This improves space utilization and better meets the required number of switches, achieving the desired effect.

[0028] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
