Abstract
Description
Technical Field
[0001] This utility model belongs to the field of switch technology, and in particular relates to a PoE network switch. Background Technology
[0002] A PoE network switch, or Power over Ethernet switch, is a network device that can transmit data signals and power simultaneously over an Ethernet cable. Without any changes to the existing Ethernet Cat.5 cabling infrastructure, a PoE switch can provide DC power to IP-based terminals, such as IP phones, wireless LAN access points (APs), and network cameras, while transmitting data signals.
[0003] However, existing PoE network switches have some problems that need to be solved in actual use. Among them, heat dissipation is particularly prominent. Most current PoE network switches have relatively simple heat dissipation structures, relying solely on ventilation holes on the surface of the casing for passive heat dissipation. However, during operation, the internal electronic components of PoE switches continuously generate a large amount of heat. The heat dissipation efficiency of natural air convection through these ventilation holes is extremely low, and the heat cannot be dissipated in a timely and effective manner. When exposed to high temperatures for a long time, the performance of electronic components will degrade, and they may even malfunction.
[0004] Traditional PoE network switches typically use screws to connect the chassis and cover. When internal electronic components malfunction and require repair, technicians need to use screwdrivers and other tools to unscrew multiple screws to separate the chassis from the cover. This process is cumbersome and time-consuming. In addition, with a large number of screws, it is easy for screws to be lost during disassembly and installation.
[0005] To address these issues, we provide a PoE network switch. Utility Model Content
[0006] The purpose of this utility model is to provide a PoE network switch that solves the problem that existing PoE network switches rely solely on opening heat dissipation holes on the surface of the casing for passive heat dissipation, resulting in unsatisfactory heat dissipation, through the cooperation of cooling components, mounting components, and fixing components.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0008] This utility model relates to a PoE network switch, comprising a housing, a sealing plate at the top of the housing cavity, a cover fixedly connected to the top of the sealing plate, mounting components at the top of both sides of the housing, a cooling component at the bottom of the housing, fixing components on both sides of the cooling component, a connecting panel on the front of the housing, a cooling base at the bottom of the housing, a heat-conducting plate at the bottom of the housing cavity, heat dissipation fins fixedly connected to the bottom of the heat-conducting plate, a fan fixedly connected to the back of the cooling base, a mounting bracket at one side fixedly connected to the surface of the housing, mounting plates fixedly connected to both sides of the bottom of the cover, and fastening bolts threaded into the inner cavity of the mounting bracket, the fastening bolts penetratingly connecting to the mounting plates.
[0009] The present invention is further configured such that the fixing component includes a movable locking pin, one end of which is movably connected to the surface of the cooling base. Positioning frames are fixedly connected to the bottom of both sides of the housing. A fixing pin is fixedly connected to the inner cavity of the positioning frame. When the housing is moved to the top of the cooling base, the movable locking pin is rotated until one end is inserted into the inner cavity of the positioning frame. The semi-circular groove on its surface is engaged with the surface of the fixing pin. The interference fit between the semi-circular groove and the fixing pin fixes the movable locking pin in the inner cavity of the positioning frame, thereby installing the cooling base at the bottom of the housing.
[0010] The present invention is further configured such that slots are provided on both sides of the top of the housing, and a card plate is movably connected to the inner cavity of the slot. The top of the card plate is fixedly connected to the bottom of the cover. When the cover is moved until it is locked on the top of the housing, the card plate is locked into the inner cavity of the slot on the top of the housing along with the cover. The limiting structure composed of the card plate and the slot can greatly improve the connection strength between the cover and the housing.
[0011] The present invention is further provided that finger plates are fixedly connected to the top of both sides of the housing, and anti-scratch pads are provided at the bottom of the finger plates, making it more convenient to insert fingers into the inner cavity of the finger plates and pick up the switch for movement.
[0012] The present invention is further configured such that a vent is provided on the front of the cooling base, and a dustproof net is provided in the inner cavity of the vent. The hot gas in the inner cavity of the cooling base can be discharged through the vent, and the dustproof net in the inner cavity of the vent can filter the dust in the air and prevent a large amount of external dust from entering the inner cavity of the casing through the vent.
[0013] The present invention is further provided that a pinch pin is fixedly connected to one side of the movable locking pin, and the surface of the pinch pin is provided with anti-slip texture, making it more convenient to rotate the movable locking pin by pinching the pinch pin with your fingers.
[0014] The present invention is further configured such that support pads are fixedly connected to both sides of the bottom of the cooling base, and anti-slip particles are provided on the bottom of the support pads. The anti-slip particles can improve the anti-slip properties of the bottom of the support pads, and the support pads with good anti-slip properties can provide stable support for the bottom of the cooling base.
[0015] The present invention is further configured such that clamp frames are fixedly connected to the top of both sides of the inner cavity of the cooling base, and buckle plates are fixedly connected to both sides of the bottom of the housing. As the housing is placed on top of the cooling base, the buckle plates at the bottom of the housing are inserted into the inner cavity of the clamp frames. The limiting structure composed of the buckle plates and clamp frames can improve the installation strength between the cooling base and the housing.
[0016] The present invention has the following beneficial effects.
[0017] 1. This utility model adopts an innovative quick installation design. The cover and the housing, as well as the cooling base and the housing, are connected by snap-fit positioning (the cover is snapped into the top of the housing and the mounting plate is snapped into the mounting bracket) and simple fasteners (the interference fit of fastening bolts, movable snap pins and fixed pins). This modular structure eliminates complicated tools and steps, and significantly simplifies the on-site assembly, disassembly and maintenance process of the equipment.
[0018] 2. The built-in active heat dissipation mechanism of this utility model can cope with the high heat generated by POE power supply. When the internal temperature exceeds the threshold, the temperature control system automatically starts the fan. The fan drives the airflow to circulate at high speed in the specially designed cooling base. Combined with the heat conduction plate (efficiently dissipating heat from the circuit board) and heat dissipation fins (increasing the heat dissipation area), the forced convection air can quickly remove the heat from the surface of the heat dissipation fins, thereby achieving rapid and efficient cooling of the core components.

Detailed Implementation
[0028] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Example 1
[0030] Please see Figure 1-7 This utility model is a PoE network switch, including a housing 1, a sealing plate 2 is provided on the top of the inner cavity of the housing 1, a cover 3 is fixedly connected to the top of the sealing plate 2, mounting components 4 are provided on the top of both sides of the housing 1, a cooling component 5 is provided on the bottom of the housing 1, a fixing component 6 is provided on both sides of the cooling component 5, a connecting panel 7 is provided on the front of the housing 1, the cooling component 5 includes a cooling base 501, the cooling base 501 is provided on the bottom of the housing 1, a heat conduction plate 502 is provided on the bottom of the inner cavity of the housing 1, a heat dissipation fin 503 is fixedly connected to the bottom of the heat conduction plate 502, a fan 504 is fixedly connected to the back of the cooling base 501, the mounting component 4 includes a mounting bracket 401, one side of the mounting bracket 401 is fixedly connected to the surface of the housing 1, mounting plates 402 are fixedly connected to both sides of the bottom of the cover 3, a fastening bolt 403 is threadedly connected to the inner cavity of the mounting bracket 401, and the fastening bolt 403 is through-connected to the mounting plate 402.
[0031] Specifically: The movable cover 3 is snapped onto the top of the housing 1, and the mounting plate 402 is then snapped into the inner cavity of the mounting bracket 401. The fastening bolt 403 is rotated until one end passes through the insertion hole on the surface of the mounting plate 402, until the pressure pad on the surface of the fastening bolt 403 presses against the surface of the mounting plate 402, thereby quickly installing the cover 3 on the top of the housing 1. During the operation of the switch, heat is generated inside. When the heat exceeds the set value, the control mechanism automatically turns on the fan 504. The fan 504 draws outside air into the inner cavity of the cooling base 501. The heat conduction plate 502 conducts heat out of the circuit board in the inner cavity of the housing 1, and the heat dissipation fins 503 dissipate heat quickly. The fan 504 increases the air circulation speed in the inner cavity of the cooling base 501, and the rapidly circulating air quickly removes the heat from the surface of the heat dissipation fins 503.
[0032] Example 2
[0033] Please see Figure 1-7 Based on Embodiment 1, the fixing component 6 includes a movable locking pin 601, one end of which is movably connected to the surface of the cooling base 501. Positioning frames 602 are fixedly connected to the bottom of both sides of the housing 1, and fixing pins 603 are fixedly connected to the inner cavity of the positioning frames 602. Slots are provided on both sides of the top of the housing 1, and a locking plate is movably connected to the inner cavity of the slot. The top of the locking plate is fixedly connected to the bottom of the cover 3. Finger plates are fixedly connected to the top of both sides of the housing 1, and anti-scratch pads are provided at the bottom of the finger plates. A vent is provided on the front of the cooling base 501, and a dustproof net is provided in the inner cavity of the vent. A pinch pin is fixedly connected to one side of the movable locking pin 601, and anti-slip textures are provided on the surface of the pinch pin. Support pads are fixedly connected to both sides of the bottom of the cooling base 501, and anti-slip particles are provided at the bottom of the support pads. Clamp frames are fixedly connected to the top of both sides of the inner cavity of the cooling base 501. Buckle plates are fixedly connected to both sides of the bottom of the housing 1.
[0034] Specifically: Move the housing 1 to its position at the top of the cooling base 501, rotate the movable locking pin 601 until one end of it enters the inner cavity of the positioning frame 602, and the semi-circular groove on its surface engages with the surface of the fixing pin 603. The interference fit between the semi-circular groove and the fixing pin 603 fixes the movable locking pin 601 in the inner cavity of the positioning frame 602, thereby installing the cooling base 501 at the bottom of the housing 1. Move the cover 3 to its position at the top of the housing 1, and the locking plate, along with the cover 3, engages with the locking groove in the inner cavity of the top of the housing 1. The limiting structure formed by the locking plate and the locking groove greatly improves the connection strength between the cover 3 and the housing 1. Insert your finger into the inner cavity of the finger plate and use the finger plate to pick up the switch and move it. More conveniently, the high-temperature gas inside the cooling base 501 can be discharged through the vent, and the dustproof net inside the vent can filter dust in the air, preventing a large amount of external dust from entering the inner cavity of the housing 1 through the vent. It is more convenient to pinch the finger pin and rotate the movable locking pin 601 by pinching the finger pin. The anti-slip particles can improve the anti-slip properties of the bottom of the support pad. The support pad with good anti-slip properties can provide stable support for the bottom of the cooling base 501. As the housing 1 is placed on top of the cooling base 501, the buckle plate at the bottom of the housing 1 is inserted into the inner cavity of the clamp frame. The limiting structure composed of the buckle plate and the clamp frame can improve the installation strength between the cooling base 501 and the housing 1.
[0035] The working principle of this utility model is as follows: The movable cover 3 is snapped onto the top of the housing 1, and the mounting plate 402 is then snapped into the inner cavity of the mounting bracket 401. The fastening bolt 403 is rotated until one end of it passes through the insertion hole on the surface of the mounting plate 402, until the pressure pad on the surface of the fastening bolt 403 presses against the surface of the mounting plate 402, thereby quickly installing the cover 3 onto the top of the housing 1. Then, the installed housing 1 is placed on top of the cooling base 501, and the movable locking pin 601 is rotated until one end of it is inserted into the inner cavity of the positioning frame 602. The semi-circular groove on its surface is engaged with the surface of the fixing pin 603. The interference fit between the semi-circular groove and the fixing pin 603 secures the movable locking pin. 601 is fixed in the inner cavity of the positioning frame 602, thereby installing the cooling base 501 at the bottom of the housing 1. During the operation of the switch, heat is generated inside. When the heat exceeds the set value, the control mechanism automatically turns on the fan 504. The fan 504 draws outside air into the inner cavity of the cooling base 501. The heat conduction plate 502 conducts heat out of the circuit board in the inner cavity of the housing 1, and the heat dissipation fins 503 dissipate heat quickly. The fan 504 increases the air circulation speed in the inner cavity of the cooling base 501. The rapidly circulating air quickly removes the temperature from the surface of the heat dissipation fins 503, thereby rapidly cooling the inner cavity of the housing 1.
