Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to a switch. Background Technology

[0002] A switch is a network device used for forwarding electrical signals, providing a dedicated electrical signal path for connected network nodes. Common Ethernet switches are widely used in communication engineering for auxiliary network connections to ensure fast, secure, and accurate communication. Currently, most switches used in communication engineering adopt an integrated design, where all components of the switch are tightly integrated into a single unit. However, because the number of interfaces is fixed during manufacturing, it lacks scalability. In practical applications, if the number of network nodes increases or communication needs change, requiring more interfaces, existing integrated switches cannot easily increase the number of interfaces in a simple way. Utility Model Content

[0003] The main purpose of this utility model is to provide a switch that allows for the flexible addition or replacement of interface modules according to actual needs.

[0004] To achieve the above objectives, this utility model proposes a switch comprising:

[0005] The housing includes a shell and two cover plates. The shell has a cavity and two openings communicating with the cavity and disposed opposite to each other. The two cover plates are detachably connected to the housing and cover the two openings.

[0006] A motherboard assembly, wherein the motherboard assembly is disposed in the cavity;

[0007] Of the two cover plates, one is a power interface plate and the other is a terminal block plate.

[0008] In one embodiment, the housing includes two bottom plates and two side plates arranged opposite to each other, with each side plate connected to the two bottom plates to jointly enclose and form the cavity.

[0009] In one embodiment, the housing further includes a plug-in plate disposed on the side of the cover plate near the cavity; the plug-in plate has a first fixing hole on the side near the bottom plate;

[0010] The base plate has a first through hole corresponding to the first fixing hole;

[0011] The switch also includes a first fixing member, the locking end of which passes through the first through hole and is locked in the first fixing hole, so that the plug-in plate and the base plate are connected as one unit.

[0012] In one embodiment, the switch further includes an auxiliary mounting component, which includes a fixing plate and a mounting plate. The fixing plate is detachably connected to a side plate and is disposed near an opening. One end of the mounting plate is rotatably connected to one end of the fixing plate. The mounting plate has a stop position that covers part of the opening and an open position that opens the opening. The mounting plate has a second fixing hole.

[0013] The cover plate has a second through hole;

[0014] The switch also includes a second fixing member. When the mounting plate is in the stop position, the second fixing hole and the second through hole are correspondingly arranged. The locking end of the second fixing member passes through the second through hole and is locked in the second fixing hole, so that the mounting plate and the cover plate are connected as one unit.

[0015] In one embodiment, the switch includes four auxiliary mounting components, wherein two of the auxiliary mounting components are respectively disposed at both ends of one side plate, and the other two auxiliary mounting components are respectively disposed at both ends of another side plate.

[0016] In one embodiment, at least one of the base plates is detachably connected to both of the side plates.

[0017] In one embodiment, the motherboard includes a circuit board and a heat-generating device, the heat-generating device being disposed on the circuit board;

[0018] The switch also includes a heat sink, which is disposed in the cavity. One side of the heat sink is thermally connected to the heat-generating device, and the side of the heat sink facing away from the heat-generating device is thermally connected to the housing.

[0019] In one embodiment, the heat sink has a plurality of heat dissipation fins on the side facing away from the heat-generating device, and the heat dissipation fins are thermally connected to the housing.

[0020] In one embodiment, the housing has ventilation holes communicating with the cavity, and a plurality of heat dissipation fins are exposed in the cavity through the ventilation holes.

[0021] In one embodiment, the cover plate has at least one heat dissipation hole.

[0022] The switch provided by this utility model, through the adoption of a detachable cover design, constructs a flexible and adjustable interface expansion system, effectively solving the problem of poor interface expandability in traditional switches. Specifically, the switch chassis consists of a shell and two detachable covers. The shell forms a cavity to accommodate the motherboard components and has two opposing openings. The two covers cover the openings and are detachably connected to the shell. One cover is a power interface board, and the other is a terminal block. This structural design is based on a modular concept, clearly dividing the interface functions: the power interface board focuses on power supply-related interfaces, while the terminal block handles data transmission and other interfaces. This partitioning makes subsequent interface expansion more targeted. In practical applications, when the communication engineering scenario changes, such as the addition of network nodes requiring more data transmission interfaces, or the introduction of new equipment requiring a specific type of power interface (DC or AC), users can disassemble the corresponding terminal block or power interface board as needed, open the chassis to modify the internal motherboard components, and replace them with new terminal blocks or power interface boards with different interfaces. With its removable cover and functional partition design, this switch can quickly adapt to network expansion or new device access by simply replacing the cover. This significantly enhances the practicality and versatility of the device, effectively avoiding the high costs associated with frequent switch replacements due to insufficient interfaces. As a result, it can better meet the complex and ever-changing network connection needs in communication engineering, providing strong support for the flexible deployment and efficient operation of communication projects.

[0032] This utility model proposes a switch 100.

[0033] Please see Figure 1In one embodiment, the switch 100 includes a housing 1 and a motherboard assembly 2. The housing 1 includes a shell 11 and two cover plates 12. The shell 11 has a cavity and two openings that communicate with the cavity and are disposed opposite to each other. The two cover plates 12 are detachably connected to the housing and cover the two openings. The motherboard assembly 2 is disposed in the cavity. Among the two cover plates 12, one cover plate 12 is a power interface board 121 and the other cover plate 12 is a terminal block board 122.

[0034] In this embodiment, the housing 11 is the basic structure of the switch 100. Its shape can be designed as a cuboid, cube, cylinder, irregular shape, or polygon, etc., to meet different installation space and functional requirements. The cuboid housing 11 is regular and efficient, suitable for standard rack installation; the cube housing 11 is compact and aesthetically pleasing, suitable for small environments; the cylindrical housing 11 has strong impact resistance and good heat dissipation; the irregular and polygonal housings 11 can be customized to meet special needs. The housing 11 can be made of metals such as aluminum alloy and stainless steel, which have good strength and heat dissipation performance; it can also be made of plastics such as ABS and PC, which are low in cost and have good insulation; or carbon fiber composite materials can be used to achieve high strength and lightweight.

[0035] The power interface board 121 is a dedicated interface board on the switch 100 used for connecting power supplies. It typically contains multiple power interfaces to provide a stable power supply to the motherboard and other components. The power interface board 121 is designed to ensure reliable power connection and distribution, and also features overvoltage and overcurrent protection functions to ensure the safe operation of the switch 100. The terminal block 122 is a device for connecting electrical circuits. It typically consists of a base plate and multiple electrical connection points, primarily used to connect multiple cables or wires to a single board for easy management and maintenance. The terminal block 122 can perform functions such as signal transmission and power distribution.

[0036] The switch 100 provided by this utility model, through the adoption of a detachable cover plate 12 design, constructs a flexible interface expansion system, effectively solving the problem of poor interface expandability of traditional switches 100. Specifically, the chassis 1 of the switch 100 consists of a housing 11 and two detachable covers 12. The housing 11 forms a cavity to accommodate the motherboard assembly 2 and has two opposing openings. The two covers 12 respectively cover the openings and are detachably connected to the housing 11. One cover 12 is a power interface board 121, and the other is a terminal block 122. This structural design is based on the modular concept, clearly dividing the interface functions: the power interface board 121 focuses on power supply-related interfaces, and the terminal block 122 is responsible for data transmission and other interfaces. This partitioning method makes subsequent interface expansion more targeted. In practical applications, when communication engineering scenarios change, such as the addition of network nodes requiring more data transmission interfaces, or the introduction of new equipment requiring specific types of power interfaces (DC or AC), users can disassemble the corresponding terminal block 122 or power interface board 121 as needed, open the casing 1 to modify the internal motherboard assembly 2, and replace it with a new terminal block 122 or power interface board 121 with different interfaces. Through this removable cover 12 and functional partition design, whether the network scale expands or new equipment is added, the switch 100 can quickly adapt to interface expansion by replacing the cover 12, significantly enhancing the practicality and versatility of the equipment. This effectively avoids the high costs incurred by frequently replacing the switch 100 due to insufficient interfaces, thus better meeting the complex and ever-changing network connection needs in communication engineering, and providing strong support for the flexible deployment and efficient operation of communication engineering projects.

[0037] Please see Figure 1 In one embodiment, the housing 11 includes two opposing base plates 111 and two opposing side plates 112. Both side plates 112 are connected to the two base plates 111 to jointly enclose a cavity. This structural design gives the housing 11 good stability and structural strength, providing reliable support and protection for the internal motherboard assembly 2. Simultaneously, the two opposing openings facilitate the installation and removal of the cover plate 12, providing convenience for subsequent interface expansion.

[0038] Please see Figure 2In one embodiment, the housing 1 further includes a plug-in plate 13, which is disposed on the side of the cover plate 12 near the cavity. A first fixing hole 131 is formed on the side of the plug-in plate 13 near the bottom plate 111. A first through hole 1111 is formed on the bottom plate 111 corresponding to the first fixing hole 131. The switch 100 also includes a first fixing member, the locking end of which passes through the first through hole 1111 and is locked in the first fixing hole 131, so that the plug-in plate 13 and the bottom plate 111 are connected as a single unit. Through the cooperation of the plug-in plate 13 and the first fixing member, a detachable connection between the cover plate 12 and the housing 11 is achieved. This connection method is not only convenient to install but also provides a firm and reliable connection. When the cover plate 12 needs to be replaced, only the first fixing member needs to be removed to easily remove the cover plate 12 and replace it with a cover plate 12 with more interfaces, thereby achieving flexible expansion of the number of interfaces. It should be noted that the first fastener can be a screw, bolt and nut, self-tapping screw, rivet, or locking washer, etc., used to firmly fix the cover plate 12 to the housing 1. Screws achieve detachable connection through threaded engagement; bolts and nuts provide high-strength fixation through tightening; self-tapping screws are suitable for thin materials and can cut their own threads; rivets achieve permanent connection through deformation and have high strength; locking washers are used to prevent loosening due to vibration.

[0039] Please see Figure 1 and Figure 2 In one embodiment, the switch 100 further includes an auxiliary mounting component 3, which includes a fixing plate 31 and a mounting plate 32. The fixing plate 31 is detachably connected to a side plate 112 and is positioned near an opening. One end of the mounting plate 32 is rotatably connected to one end of the fixing plate 31. The mounting plate 32 has a stop position covering the opening and an open position where the opening is open. The mounting plate 32 has a second fixing hole 321. The cover plate 12 has a second through hole. The switch 100 also includes a second fixing member. When the mounting plate 32 is in the stop position, the second fixing hole 321 and the second through hole are correspondingly positioned. The locking end of the second fixing member passes through the second through hole and locks into the second fixing hole 321, so that the mounting plate 32 and the cover plate 12 are connected as one unit. In this embodiment, the auxiliary mounting component 3 further improves the stability and reliability of the cover plate 12 installation. When installing the cover plate 12, first rotate the mounting plate 32 to the open position, place the cover plate 12 in place, and then rotate the mounting plate 32 to the stop position. The second fastener connects the mounting plate 32 and the cover plate 12 into one unit, thereby achieving a stable installation of the cover plate 12. This structural design not only facilitates the installation and removal of the cover plate 12, but also effectively prevents the cover plate 12 from loosening or falling off during use.

[0040] In one embodiment, the switch 100 includes four auxiliary mounting components 3, two of which are respectively disposed at both ends of one side panel 112, and the other two are respectively disposed at both ends of the other side panel 112. In this embodiment, by providing auxiliary mounting components 3 at both ends of the side panel 112, the force on the cover plate 12 can be distributed more evenly, further improving the stability of the cover plate 12 installation. At the same time, this symmetrical layout also makes the structure of the entire switch 100 more aesthetically pleasing and reasonable.

[0041] In one embodiment, at least one base plate 111 is detachably connected to two side plates 112. This detachable connection method makes the assembly of the housing 11 more flexible and convenient. During the manufacturing process, the side plates 112 and the base plate 111 can be processed separately and then assembled, which facilitates the adjustment and optimization of the internal structure of the housing 11. At the same time, when the switch 100 needs to be repaired or upgraded, the housing 11 can be quickly disassembled to facilitate the operation of the internal components.

[0042] Please see Figure 1 During the operation of the switch 100, the heat-generating device 22 generates a large amount of heat. If this heat cannot be dissipated in time, it may lead to a decrease in the performance of the switch 100 or even damage. To solve the above problem, in one embodiment, the motherboard includes a circuit board 21 and a heat-generating device 22, with the heat-generating device 22 disposed on the circuit board 21. The switch 100 also includes a heat sink 4, which is disposed in the cavity. One side of the heat sink 4 is thermally connected to the heat-generating device 22, and the side of the heat sink 4 facing away from the heat-generating device 22 is thermally connected to the housing 11. In this embodiment, the heat sink 4 can be a metal heat sink, a heat pipe heat sink 4, a fan heat sink 4, a liquid cooling heat sink 4, or thermal paste, etc., used to conduct and dissipate the heat inside the switch 100 to the external environment, so as to keep the device operating within the normal temperature range and ensure its stability and performance. By setting the heat sink 4, the heat generated by the heat-generating device 22 can be quickly conducted to the housing 11 and then dissipated to the external environment through the housing 11, thereby effectively reducing the internal temperature of the switch 100 and ensuring the stable operation of the switch 100.

[0043] In one embodiment, the heat sink 4 has multiple heat dissipation fins 41 on the side facing away from the heat-generating device 22, and the heat dissipation fins 41 are thermally connected to the housing 11. In this embodiment, the heat dissipation area can be increased by the heat dissipation fins 41, so that the heat from the heat-generating device 22 can be quickly conducted to the housing 11 and dissipated into the external environment, thereby effectively reducing the internal temperature of the device and ensuring the stable operation of the switch 100.

[0044] Please see Figure 2In one embodiment, the housing 11 has ventilation holes 113 communicating with the cavity, through which multiple heat dissipation fins 41 are exposed. In this embodiment, the ventilation holes 113 not only provide a channel for the heat dissipation fins 41 to directly contact the outside air, further improving the heat dissipation effect, but also promote the circulation of air inside the cavity, preventing heat from accumulating inside the cavity, thereby creating a better heat dissipation environment for the switch 100. It should be noted that the heat dissipation fins 41 need to be set as close as possible to the edge of the ventilation holes 113 to prevent dust from entering the cavity.

[0045] In one embodiment, the cover plate 12 has at least one heat dissipation hole. The heat dissipation hole can further enhance the heat dissipation performance of the switch 100. During the operation of the switch 100, heat will be dissipated to the outside through the cover plate 12. The heat dissipation hole provides more channels for heat dissipation, allowing heat to be dissipated to the external environment more quickly, further reducing the internal temperature of the switch 100 and improving the operational stability of the switch 100.

[0046] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
