Description

Technical Field

[0001] This utility model relates to the field of WiFi antenna technology, and in particular to an industrial-grade waterproof WiFi antenna. Background Technology

[0002] A WiFi antenna is an antenna installed on a router, primarily used to send and receive wireless signals, enhancing the reception and transmission capabilities of a wireless network. By changing the angle of the WiFi antenna or increasing the number of antennas, the coverage and strength of the WiFi signal can be improved. In homes, schools, factories, and public areas, routers are often used to send and receive wireless network signals to achieve full network coverage. Especially in industrial settings with outdoor network coverage areas, WiFi antennas need to be extended outside the factory buildings for outdoor use to ensure high-quality wireless network signal transmission.

[0003] Currently, Wi-Fi antennas are typically connected to routers via threaded connections and then placed outdoors in factory environments. However, due to the complex factory environment, Wi-Fi antennas are prone to loosening in harsh outdoor conditions such as high temperature and humidity or wind and rain. This can cause moisture to seep into the connection point between the Wi-Fi antenna and the router, potentially damaging the router. Therefore, to ensure the stability and lifespan of the Wi-Fi antenna, it is necessary to prevent external water from entering the antenna. Existing technology typically involves completely covering the Wi-Fi antenna to prevent water ingress at the connection point, achieving a waterproof and moisture-proof effect. However, this method can affect the transmission of wireless signals and impact the signal quality of the Wi-Fi antenna. Utility Model Content

[0004] To address the technical problem that existing waterproofing methods for WiFi antennas can affect wireless signal transmission and WiFi antenna signal quality, this utility model provides the following technical solution.

[0005] This utility model discloses an industrial-grade waterproof WiFi antenna, comprising an antenna sleeve sealed with a connecting post, a radiating element and a PCB antenna board located inside the antenna sleeve, the PCB antenna board being connected to an RF cable passing through one end of the connecting post and connected to an IPEX terminal, the connecting post including a threaded end penetrating the outer wall of the router, and the outer periphery of the threaded end being provided with an outer sealing gasket located on the outside of the router, an inner sealing ring located on the inside of the router, double-sided serrations and a nut.

[0006] As a further technical solution, the connecting post is provided with a groove on one side of the threaded end, and the outer sealing gasket is provided with a sealing protrusion embedded in the groove.

[0007] As a further technical solution, the outer sealing gasket is provided with a sealing ring and several anti-slip pieces located inside the sealing ring on the side away from the sealing protrusion.

[0008] As a further technical solution, the anti-slip sheet is a wedge-shaped sheet.

[0009] As a further technical solution, the connecting post includes a sealed end that is glued to the antenna sleeve.

[0010] As a further technical solution, the double-sided serrated surface is a metal or plastic sheet with serrated structures on both sides.

[0011] As a further technical solution, the outer sealing gasket is made of rubber material.

[0012] The beneficial effects of this utility model are as follows: When the connecting post of this industrial-grade waterproof WiFi antenna is connected to the router, the threaded end is sequentially provided with an outer sealing gasket on the outside of the router, an inner sealing ring on the inside of the router, double-sided serrations, and a nut. This allows for simultaneous sealing from both the outside and inside of the router, effectively preventing moisture from entering the router and antenna. Furthermore, the outer sealing gasket has a sealing ring and multiple anti-slip pads on the side facing the router. The structure of the anti-slip pads and double-sided serrations provides anti-loosening treatment from both directions of the threaded end, preventing the antenna connecting post from loosening in harsh outdoor environments and ensuring the stability of the WiFi antenna and router. Therefore, waterproofing and moisture-proofing are achieved without completely covering the antenna, without affecting the signal transmission quality of the WiFi antenna, ensuring the stability and lifespan of the WiFi antenna.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0016] like Figure 1 As shown, in a preferred embodiment, the present invention provides an industrial-grade waterproof WiFi antenna, including a connecting post 4 penetrating a router, and an antenna sleeve 1 sealed to the connecting post 4. The antenna sleeve 1 is made of ABS+PC composite material and can pass the dual 85 test. In this case, the connecting post 4 has a hollow sealing end 401 on the side facing the antenna sleeve 1. The outer wall shape of the sealing end 401 matches the inner wall shape of the antenna sleeve 1, and the sealing end 401 and the antenna sleeve 1 are sealed together by adhesive bonding.

[0017] The inner cavity of the antenna sleeve 1 houses a radiating element 2 and a PCB antenna board 3. The radiating element 2 is made of pure copper plated with gold, which has excellent conductivity, strong corrosion resistance, and low surface loss. The PCB antenna board 3 serves as the antenna ground and fixes the antenna radiating element. The PCB antenna board 3 is connected to an RF line 9 that passes through a connecting post 4. The end of the RF line 9 away from the connecting post 4 is connected to an IPEX terminal 10.

[0018] like Figure 2 As shown, in a preferred embodiment, the connecting post 4 includes a threaded end 402 penetrating the outer wall of the router. The outer periphery of the threaded end 402 is sequentially provided with an outer sealing gasket 5 located on the outside of the router, an inner sealing ring 6 located on the inside of the router, a double-sided toothed ring 7, and a nut 8. Figure 2In this design, the threaded end 402 penetrates the outer wall of the router. The outer sealing gasket 5 is located on the outside of the router, while the inner sealing ring 6, double-sided toothed 7, and nut 8 are located on the inside of the router. The double-sided toothed 7 is a metal or plastic sheet with teeth on both sides, which has an anti-loosening effect and can effectively prevent the inner sealing ring 6 and nut 8 from rotating randomly. Therefore, sealing can be performed simultaneously from both the outside and inside of the router, effectively preventing moisture from entering the router and antenna.

[0019] like Figure 3 As shown, in a preferred embodiment, the connecting post 4 has a groove 403 located on one side of the threaded end 402, and the outer sealing gasket 5 has a sealing protrusion 501 embedded in the groove 403. After the sealing protrusion 501 is embedded in the groove 403, it can effectively seal the side of the connecting post 4 facing the router. At the same time, a sealing ring 502 is provided on the side of the outer sealing gasket 5 away from the sealing protrusion 501. The sealing ring 502 is located on the outer peripheral edge of the outer sealing gasket 5 and is used to seal the outside of the router to prevent moisture from entering.

[0020] In a preferred embodiment, the outer sealing gasket 5 is made of a one-piece molded rubber material, and the inner side of the sealing ring 502 is provided with multiple anti-slip pieces 503. After the sealing ring 502 and the anti-slip pieces 503 are pressed against the outer wall of the router, the anti-slip pieces 503 have an anti-loosening effect and can prevent the connecting post 4 from rotating. In this embodiment, the anti-slip piece 503 is a wedge-shaped piece. Of course, the anti-slip piece 503 can also be a triangular piece, a cylindrical piece, or other shapes and structures with anti-slip and wear-resistant properties. This utility model does not make any particular limitation on it.

[0021] During installation, the following steps are taken: First, the sealing protrusion 501 of the outer sealing gasket 5 is embedded into the groove 403, and then the threaded end 402 is inserted into the router. Next, the inner sealing ring 6, double-sided toothed 7, and nut 8 are sequentially fitted onto the threaded end 402 from the inside of the router, and the nut 8 is tightened. During the tightening process, the nut 8 moves relative to the threaded end 402. While the nut 8 presses against the double-sided toothed 7, the double-sided toothed 7 also presses against the inner sealing ring 6, sealing the inside of the router. Simultaneously, the threaded end 402 causes the outer sealing gasket 5 to press against the outer wall of the router, effectively sealing the connection between the router and the antenna. This completes the installation of the WiFi antenna and the router, prevents the connecting post 4 from loosening, and ensures the stability and lifespan of the WiFi antenna and the router.

[0022] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
