[0002] A circuit board signal enhancement device is a device specifically designed to enhance the signal strength on circuit boards or electronic devices. Its core working principle involves amplifying weak received signals through a series of circuits and technical means, thereby improving signal strength and stability.

[0003] Signal enhancement on circuit boards can also be achieved through external antennas, reflective beamforming structures, and other means. Among these, a dome-shaped reflector is quite common. However, dome-shaped reflectors are usually fixed on the antenna guide rod and cannot be disassembled or adjusted. As a result, if the guide rod shifts, it is equivalent to the entire device being damaged, and the replacement cost is high.

[0004] Therefore, this application provides a circuit board signal enhancement device to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a circuit board signal enhancement device, which aims to solve the problem of high subsequent maintenance and replacement costs caused by the fact that existing circuit board signal enhancement devices, which utilize a dish reflector to enhance signals, are usually fixedly mounted on an antenna guide rod.

The bottom end of the cluster reflector has a retaining head corresponding to the slot. This design of the cluster reflector effectively enhances signal strength and stability, improves the signal reception capability of the circuit board, and the adjustment mechanism allows for easy disassembly and repositioning of the cluster reflector without requiring complete replacement, reducing maintenance and replacement costs.

[0008] Preferably, the cluster reflector includes a first fan plate and a second fan plate arranged symmetrically. The first fan plate has a positioning post on the side near the second fan plate, and the second fan plate has a positioning hole corresponding to the positioning post on the side near the first fan plate.

[0010] Preferably, the radio frequency circuit board is fixedly installed inside the metal casing, and the antenna connector of the radio frequency circuit board passes through the top of the metal casing and extends to the outside, and the bottom end of the antenna guide rod has a hexagonal nut that is screwed to the antenna connector.

[0011] Preferably, an upper limit ring and a lower limit ring are fixedly connected to the outer wall of the antenna guide rod at positions above and below the adjustment mechanism, respectively.

[0012] Preferably, there is a distance between the upper limit ring and the lower limit ring to accommodate the adjustment of the cluster reflector.

[0013] The signal enhancement device for this circuit board features a clustered reflector design that effectively enhances signal strength and stability, improving the circuit board's signal reception capability. Furthermore, the adjustable mechanism allows for easy disassembly and repositioning of the clustered reflector without requiring complete replacement, thus reducing maintenance and replacement costs.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] This embodiment provides a circuit board signal enhancement device, such as... Figures 1-3 As shown, the circuit board signal enhancement device includes an RF circuit board 3 and an antenna guide rod 2 connected to the RF circuit board 3. A cluster reflector 22 is fitted outside the antenna guide rod 2, and an adjustment mechanism 23 is fitted outside the antenna guide rod 2, which moves along the axial direction of the antenna guide rod 2 to fix the cluster reflector 22.

[0024] The adjustment mechanism 23 includes a ring 231 fitted on the outside of the antenna guide rod 2, a slot 2311 opened at the top of the ring 231, a bolt 2312 screwed to the side of the ring 231 with its end in contact with the outer wall of the antenna guide rod 2 for locking the ring 231 on the antenna guide rod 2, and a retaining ring 232 fitted on the outside of the antenna guide rod 2 with its bottom end in contact with the top of the ring 231 for filling the gap between the inner ring of the cluster reflector 22 and the outer wall of the antenna guide rod 2. The bottom end of the cluster reflector 22 has a retaining head 2211 corresponding to the slot 2311.

[0025] In use, the RF circuit board 3, as the main part of signal processing, is connected to the antenna guide rod 2 and is responsible for signal reception and preliminary processing. The antenna guide rod 2, as the main structure for signal transmission and guidance, is externally fitted with a cluster reflector 22 to enhance signal strength and stability. When it is necessary to fix the position of the retaining ring 231, simply rotate the locking bolt 2312 so that its end tightly abuts against the antenna guide rod 2, thereby locking the retaining ring 231. When installing the cluster reflector 22, simply clip its head 2... Align 211 with the slot 2311 and push it down until the clip 2211 is fully inserted into the slot 2311. The main function of the clip ring 232 is to fill the gap between the inner ring of the cluster reflector 22 and the outer wall of the antenna guide rod 2, enhance the stability of the cluster reflector 22 and prevent it from loosening. When it is necessary to adjust the position of the cluster reflector 22, simply loosen the bolt 2312, and then move the support ring 231 and the cluster reflector 22 along the axial direction of the antenna guide rod 2 to the desired position, and then tighten the bolt 2312 again.

[0026] Furthermore, the cluster reflector 22 includes a first panel 221 and a second panel 222 arranged symmetrically. The side of the first panel 221 near the second panel 222 has a positioning post 2212, and the side of the second panel 222 near the first panel 221 has a positioning hole corresponding to the positioning post 2212. During installation, simply align the positioning post 2212 with the positioning hole and insert it to achieve precise positioning and stable connection of the two panels without the need for additional fasteners, simplifying the installation process. This split-panel design facilitates installation and disassembly, and also makes it convenient to replace or maintain individual panels.

[0027] Furthermore, the RF circuit board 3 is encased in a metal casing 1 and a cover 11 that covers the opening of the metal casing 1. Each of the four corners of the metal casing 1 is screwed with an internal hex bolt 12 that penetrates the cover 11. The metal casing 1 provides electromagnetic shielding for the circuit board, reducing the impact of external electromagnetic interference on the circuit board. The cover 11 covers the opening of the metal casing 1 and is secured by the internal hex bolts 12 screwed at the four corners, ensuring the airtightness of the casing.

[0028] Specifically, the radio frequency circuit board 3 is fixedly installed inside the metal housing 1, and the antenna connector 31 of the radio frequency circuit board 3 passes through the top of the metal housing 1 and extends to the outside. The bottom end of the antenna guide rod 2 has a hexagonal nut 21 that is screwed to the antenna connector 31. The antenna connector 31 of the radio frequency circuit board 3 passes through the top of the metal housing 1 and extends to the outside, and is screwed to the hexagonal nut 21 at the bottom end of the antenna guide rod 2, thereby realizing signal transmission between the circuit board and the antenna guide rod.

[0029] Furthermore, an upper limit ring 24 and a lower limit ring 25 are fixedly connected to the outer wall of the antenna guide rod 2 at positions above and below the adjustment mechanism 23, respectively. There is a distance between the upper limit ring 24 and the lower limit ring 25 to accommodate the adjustment of the cluster reflector 22. These two limit rings together limit the adjustable range of the cluster reflector 22 on the antenna guide rod, preventing the reflector from slipping or exceeding the preset position during the adjustment process.

[0030] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
