Description

Technical Field

[0001] This utility model relates to the field of PoE switch technology, and in particular to a high-efficiency waterproof PoE switch. Background Technology

[0002] PoE switches have a wide range of applications. In the security monitoring field, they can power network cameras, simplify cabling, and allow cameras to be installed in locations where power access is inconvenient, enabling comprehensive monitoring. In office environments, they can power IP phones and wireless access points, improving network flexibility and allowing employees to flexibly deploy equipment as needed. In smart buildings, they are used to power smart light bulbs, thermostats, and other smart home devices, creating a convenient and intelligent environment.

[0003] When a PoE switch is operating, it first outputs a small voltage at the port to detect the powered devices. After confirming that the devices comply with standards such as IEEE 802.3af, it classifies the devices and assesses their power requirements. Then, it quickly boosts the voltage from low to 48V DC to power the devices. It continuously provides stable power during operation, and if a device disconnects, it quickly stops supplying power and repeats the detection process. However, it has drawbacks, such as power limitations, difficulty in meeting the needs of high-power devices under older standards, poor compatibility with different brands of devices, difficulty in heat dissipation during power supply, affecting performance, and the potential for power module failure to cause power outages to all powered devices, expanding the scope of the fault.

[0004] In existing technologies, such as the outdoor waterproof PoE switch with announcement number CN217470005U, belonging to the field of PoE switch technology, it includes a bottom shell and a switch body inside the bottom shell. A rectangular frame connects the periphery of multiple ports on the switch body, and a lower closed shell and an upper closed shell are provided between the outer periphery of the rectangular frame. A top cover is connected to the top of the bottom shell, and the edge of the top cover is designed as an inclined surface for rain protection. A displacement screw is installed on one side of the bottom of the top cover, and displacement sleeves are fitted at both ends of the displacement screw. A lifting plate is provided between the displacement sleeves and the bottom of the top cover. This outdoor waterproof PoE switch can prevent rainwater and moisture from entering the ports, making it convenient for outdoor use. It is also easy to assemble and disassemble, facilitating maintenance. However, this design also has certain drawbacks. It lacks a targeted heat dissipation structure, easily accumulating heat, causing performance degradation and rapid component aging due to high temperatures. Installation relies on complex accessories or general structures, resulting in weak adaptability, difficulty in quickly assembling onto various surfaces, low installation efficiency, and inconvenience in deployment in complex scenarios.

[0005] Therefore, this application provides a high-efficiency waterproof PoE switch to solve the problems mentioned in the background art. Utility Model Content

[0009] Furthermore, a power cord is fixedly installed on one side of the switch body.

[0010] Furthermore, a connecting ring is fixedly installed on one side of the switch body.

[0011] Furthermore, several support plates are fixedly installed on one side of the housing, and a rubber frame is fixedly installed on the upper end of the support plates.

[0012] Furthermore, a retaining ring is fixedly connected to the lower end of the support plate, and a retaining block is fixedly provided at the upper end of the retaining ring.

[0013] Furthermore, two mounting plates are fixedly installed on each side of the lower end of the outer wall of the housing.

[0014] Furthermore, the upper ends of the four mounting plates are threaded with fixing screws.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a highly efficient waterproof PoE switch. A rubber frame and support plate work together to provide stable guidance for wire insertion, ensuring accurate connection. The interlocking blocks and rings ensure the rubber frame tightly fits the inserted wire, forming multiple sealing barriers that significantly improve the waterproof performance at the interface, effectively preventing rainwater and moisture intrusion. This design allows the device to stably adapt to humid environments and outdoor installation scenarios, avoiding short-circuit faults caused by water ingress into the interface, ensuring continuous and stable data transmission and power supply, extending the device's lifespan, and enhancing reliability in complex environments.

[0017] 2. This utility model proposes a high-efficiency waterproof PoE switch.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 , Figure 3 One embodiment provided by this utility model:

[0026] A high-efficiency waterproof PoE switch includes a housing 6, a sloping top cover 1 fixedly installed on the upper end of the housing 6, a flow guide groove 2 fixedly installed on the lower end of the outer wall of the sloping top cover 1, a flow guide port 5 opened on one side of the bottom end of the flow guide groove 2, a switch body 8 fixedly installed on the bottom end of the inner wall of the housing 6, and several heat dissipation holes 9 opened at the lower end of the housing 6.

[0027] Specifically, the housing 6 serves as the basic frame, supporting and protecting internal components such as the switch body 8, providing structural support for the equipment. The sloping top cover 1, made of ABS material, is designed with an inclination and connected to the housing 6 by four M3 bolts. Its edges extend 10mm beyond both sides of the housing 6, guiding rainwater to slide off quickly and preventing accumulation at the top. Simultaneously, the drainage channel 2 surrounds the bottom of the sloping top cover 1, collecting and converging rainwater before directing it out through the drainage port 5, forming a waterproof protection system that effectively prevents external rainwater from intruding into the housing 6. The drainage port 5 and the power cord 10 are staggered to prevent water from the drainage port 5 from falling onto the power cord 10. The switch body 8 is the core functional component, enabling data exchange and PoE power supply. The heat dissipation holes 9 are distributed in a 3×4 matrix at the lower end of the housing 6, creating a heat dissipation channel to promptly dissipate the heat generated by the switch body 8 during operation, maintaining stable internal temperature. The heat dissipation holes 9 are inclined at 30°, and dust filters are installed inside the holes, which can be periodically removed and cleaned to prevent clogging and ensure proper heat dissipation.

[0028] Reference Figure 3 A power cord 10 is fixedly installed on one side of the switch body 8.

[0029] Specifically, the power cord 10 is used to connect to the external power supply line, providing power to the switch body 8. It is a fundamental connection component for the device to obtain power, realize PoE power supply and data exchange functions, and ensure the power transmission between the device and the external power supply system. At the same time, a silicone sealing ring is set at the penetration point between the housing 6 and the power cord 10 to achieve radial sealing and prevent water jet intrusion.

[0030] Reference Figure 3 A connecting ring 7 is fixedly installed on one side of the switch body 8.

[0031] Specifically, the connecting ring 7 is made of nylon and is used for connecting and fixing external devices or lines. It can help to organize and bind the lines between the switch body 8 and other devices, prevent the interface from loosening due to wire pulling, facilitate wiring management, and at the same time, it can protect and limit the connection lines to a certain extent to ensure connection stability.

[0032] Reference Figure 4 Several support plates 13 are fixedly installed on one side of the housing 6, and a rubber frame 12 is fixedly installed on the upper end of the support plate 13.

[0033] Specifically, the support plate 13 provides an installation support base for the rubber frame 12, keeping it in a stable position; the rubber frame 12 is made of nitrile rubber, which has good elasticity and oil resistance. When external wires are inserted, it is responsible for tightly fitting the outer wall of the wires, filling the gaps, forming a waterproof sealing structure, effectively preventing rainwater and moisture from entering the interior of the housing 6 from the wire insertion part, and improving the overall waterproof performance of the equipment.

[0034] Reference Figure 4A retaining ring 11 is fixedly connected to the lower end of the support plate 13, and a retaining block 14 is fixedly installed on the upper end of the retaining ring 11.

[0035] Specifically, the retaining ring 11 is made of PP material and the retaining block 14 is made of elastic plastic. When the two are engaged, a pre-tightening force of 5N is generated, which compresses the rubber frame 12 to 1mm. This helps the rubber frame 12 to fit against the outer wall of the wire, thereby reinforcing and limiting the connection of the wire. This further enhances the sealing effect and connection stability at the wire insertion point, prevents the wire from loosening or falling off, and ensures the reliability of data transmission and power supply.

[0036] Reference Figure 1 Two mounting plates 3 are fixedly installed on each side of the lower end of the outer wall of the shell 6, and the upper ends of the four mounting plates 3 are threaded with fixing screws 4.

[0037] Specifically, the mounting plate 3 extends outward to provide mounting points for the fixing screws 4. It is a structural component that securely mounts the entire PoE switch onto the planar carrier. The fixing screws 4 are M4 stainless steel screws, which, in conjunction with the mounting plate 3, ensure a stable installation of the device and guarantee its stability in various application scenarios. Furthermore, the bottom of the mounting plate 3 is 5mm lower than the bottom of the housing 6, ensuring a certain distance between the housing 6 and the plane after installation, preventing water from flowing back into the ground.

[0038] Working principle: The sloping top cover 1 uses its inclined surface to allow rainwater to slide naturally into the guide channel 2. The guide channel 2 collects the rainwater and discharges it through the guide port 5, forming a top waterproof system that prevents rainwater from directly contacting the shell 6. When external wires are inserted, the support plate 13 supports the rubber frame 12. The rubber frame 12 elastically deforms and tightly fits the wire. The locking block 14 and the locking ring 11 work together to reinforce the connection, forming a waterproof seal at the interface, providing double protection to prevent moisture intrusion.

[0039] The heat generated by the switch body 8 during operation is quickly dissipated through the heat dissipation holes 9 at the bottom of the casing 6, maintaining a stable internal temperature. During installation, the device can be securely mounted on various surfaces or brackets using the mounting plate 3 and fixing screws 4, adapting to different deployment scenarios. The power cord 10 connects to external power, and the connecting ring 7 neatly arranges the wiring, ensuring continuous and stable power supply and data transmission for the device, achieving efficient waterproofing, heat dissipation, and reliable operation, adapting to the needs of complex environments.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
