Description

Technical Field

[0001] The present invention relates to the technical field of network equipment protection, in particular to a network switch with a protection structure. Background Art

[0002] Network switches play a key role in connecting and exchanging data in modern network systems. However, traditional network switches face many problems during operation. First, the heat dissipation problem is particularly prominent. The motherboard chip generates a lot of heat when running for a long time. If the heat cannot be dissipated in a timely and effective manner, the chip performance will decline, and it may even be damaged by overheating, affecting the stability and reliability of the network. The traditional heat dissipation method is to add a fan at the bottom of the network switch to cool it, but the airflow is in contact with the outer shell of the network switch and cannot quickly remove the heat inside it, resulting in poor heat dissipation effect. Secondly, many cables are connected to the switch. If there is a lack of effective positioning and fixation, the cables are prone to entanglement and loosening, affecting the stability of data transmission and inconvenient daily maintenance and management. With the rapid development of network technology and the diversification of network equipment application scenarios, it is of great practical significance to develop a network switch with a good protective structure that can effectively solve the problems of heat dissipation, dust prevention and cable management.

[0013] Beneficial effects

[0014] The present invention provides a network switch with a protective structure, which has the following beneficial effects:

[0015] When the switch is working, the motherboard chip generates heat, which is transferred to the bimetallic strip through the heat pipe. As the temperature rises, the bimetallic strip deforms and bends toward the side of the slide rod, pushing the slide rod to slide horizontally in the sleeve. The slide rod drives the flip baffle to rotate around the short axis through the connecting rod to open the vent. At this time, the cooling fan in the chassis starts, accelerating air circulation. The airflow acts directly on the inside of the switch through the vents and openings, achieving efficient heat dissipation. When the temperature drops, the bimetallic strip returns to its original shape, the slide rod returns to its original position under the action of the first spring, and the flip baffle closes the vent to prevent dust from entering. This realizes the functions of intelligently controlling ventilation, heat dissipation and dust prevention according to temperature, effectively protecting the motherboard chip and extending the service life of the switch.

[0016] The dustproof assembly features a dust screen at the bottom of the rectangular frame, effectively preventing dust from entering the switch. The rectangular frame is embedded in the enclosure and removably connected to the enclosure via a locking mechanism. This facilitates regular removal of the dust screen for cleaning or replacement, ensuring the long-term effectiveness of dust protection. This further protects the cleanliness of the switch's internal electronic components and reduces the probability of malfunctions caused by dust.

[0017] The semicircular holes on the fixed frame and movable frame of the cable positioning assembly form wire holes. The movable frame can be opened through the opening and closing structure to facilitate the insertion of cables. Then the positioning bolts are tightened to fix the cables in the wire holes to prevent them from loosening and getting entangled. The setting of the cable positioning assembly makes the cable connections of the switch more neat and orderly, which is convenient for daily maintenance and troubleshooting. At the same time, it also improves the stability of data transmission and avoids damage to the terminal heads due to external pulling of the cables. It is easy to use.

[0042] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0043] Example: When the switch body 1 is working, the motherboard chip 4 generates heat, which is transferred to the bimetallic strip 12 via the heat pipe 13. When the temperature rises to a certain level, the bimetallic strip 12 deforms and bends toward the slide bar 9, pushing the slide bar 9 to overcome the elastic force of the first spring 10 and slide horizontally within the sleeve 8. The slide bar 9 drives the flip baffle 7 to rotate around the short axis through the connecting rod 11, and the vent 6 opens. In conjunction with the cooling fan 3 in the chassis 2, cold air from the outside enters through the vent 6, removing the heat from the switch body 1 and achieving heat dissipation.

[0044] When the temperature of the switch body 1 drops, the bimetallic strip 12 returns to its original state, and the slide bar 9 is reset under the action of the first spring 10, which drives the flip baffle 7 to close the vent 6 through the connecting rod 11 to prevent dust from entering;

[0045] When the dust screen 15 needs to be cleaned or replaced, the ear plate 20 is pulled so that the latch 18 overcomes the elastic force of the second spring 19 and is withdrawn from the lock hole. The rectangular frame 14 is then removed from the enclosure 16 and the dust screen 15 is cleaned or replaced. After the cleaning or replacement operation is completed, the rectangular frame 14 is reinstalled, the ear plate 20 is loosened, and the latch 18 is inserted into the lock hole under the action of the second spring 19 to secure the rectangular frame 14.

[0046] When wiring the switch body 1, open the movable frame 25 of the cable positioning assembly, pass the cable through the wire hole 26 formed by the corresponding semicircular holes on the fixed frame 24 and the movable frame 25, then close the movable frame 25, insert the locking bolt 29 in the opening and closing structure into the locking hole of the locking seat 30 to fix the movable frame 25, and finally tighten the positioning bolt 27 to fix the cable in the wire hole 26, completing the cable connection and management, which is convenient to use.

[0047] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include," "comprise," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations. The phrase "includes an element defined by..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
