Description

Technical Field

[0001] This utility model relates to the field of antenna PCB technology, and in particular to an ultra-long high-frequency double-sided multilayer antenna PCB. Background Technology

[0002] In the field of microwave high-frequency circuit boards (such as communication antennas, satellite antennas, microwave antennas, etc.), circuit boards exceeding 800mm in length are generally referred to as ultra-long high-frequency circuit boards or ultra-long PCB antenna boards. Ultra-long antenna PCB boards are special printed circuit boards designed specifically for long-distance signal transmission and reception, playing a core role in fields such as communications, aerospace, and navigation where signal coverage and strength requirements are stringent. Ultra-long antenna PCB boards can effectively enhance the radiation performance of antennas, expand signal coverage, and ensure long-distance, high-quality communication connections for various devices in complex environments, providing strong support for the stable operation and technological development of related fields.

[0003] Existing technologies, such as the utility model patent with publication number CN209562905U, disclose an ultra-long PCB antenna board. This patent uses a substrate, on the upper surface of which a circuit board is provided. The upper surface of the substrate has a mounting groove, and a heat-conducting plate is fixedly installed inside the mounting groove. The side of the heat-conducting plate has a heat dissipation channel. Both sides of the substrate have first heat dissipation holes, the upper surface of the circuit board has second heat dissipation holes, and the upper surface of the heat-conducting plate has third heat dissipation holes. This addresses the problem that as the power of the circuit board increases during operation, the heat generated by the circuit board also increases. However, since the ultra-long PCB antenna board lacks a heat dissipation structure, its heat dissipation effect is poor, which seriously affects the service life of the ultra-long PCB antenna board.

[0004] Currently, the common practice in antenna PCB board installation is to directly insert screws into pre-drilled holes in the board. However, when tightening the screws, the screws continuously rub against the inner wall of the pre-drilled holes. As the screws rotate, this friction gradually wears down the board. If the wear intensifies, it can easily lead to board breakage, affecting the normal use of the antenna PCB board and even rendering the entire board unusable, resulting in resource waste and increased installation costs. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that once the wear and tear intensifies, the board may break, which will affect the normal use of the antenna PCB board and even lead to the scrapping of the entire board, resulting in resource waste and increased installation costs. Therefore, this invention proposes an ultra-long high-frequency double-sided multilayer antenna PCB board.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ultra-long high-frequency double-sided multilayer antenna PCB board, including a motherboard, a terminal block fixedly connected to the front surface of the motherboard, a resistor fixedly connected to the surface of the motherboard, a control chip fixedly connected to the surface of the motherboard, and an assisting component disposed inside the mounting hole of the motherboard.

[0007] Preferably, the assisting component includes a front sleeve, which is fixedly connected to the inner wall of the motherboard mounting hole. A knob is rotatably connected to the inner wall of the front sleeve, and a guide ring is fixedly connected to the inner wall of the front sleeve. A groove is formed on the surface of the knob, and the guide ring is rotatably connected to the inner wall of the groove. A threaded rod is fixedly connected to the rear surface of the knob, and a rear sleeve is fixedly connected to the rear surface of the front sleeve. A locking threaded cylinder is threadedly connected to the inner wall of the rear sleeve. The threaded rod is threadedly connected to the inner wall of the locking threaded cylinder. The user can rotate the threaded rod through the knob to ensure that the threaded rod can engage with the locking threaded cylinder, thereby driving the locking threaded cylinder to screw into the reserved mounting hole of the mounting structure.

[0008] Preferably, a first rubber pad is fixedly connected to the rear surface of the front sleeve protrusion, and a second rubber pad is fixedly connected to the front surface of the rear sleeve. The first rubber pad can protect the contact area between the front sleeve and the motherboard, thereby reducing the problem of the motherboard being squeezed and damaged due to direct contact between the front sleeve and the motherboard.

[0009] Preferably, the outer circumference of the locking threaded cylinder is provided with a guide groove, and a force-bearing ring is rotatably connected to the inner wall of the guide groove. The force-bearing ring is slidably connected to the inner wall of the rear sleeve. A compression spring is fixedly connected to the front surface of the force-bearing ring, and the end of the compression spring away from the force-bearing ring is fixedly connected to the front inner wall of the front sleeve. Through the cooperation of the force-bearing ring and the compression spring, a certain thrust can be applied to the locking threaded cylinder to ensure the stability of the locking threaded cylinder in the locked state.

[0010] Preferably, the thickness of the rear sleeve is greater than the thickness of the rear surface of the motherboard. The rear sleeve can support the motherboard to ensure that there is sufficient clearance between the back of the motherboard and the outer casing for placing the motherboard.

[0011] Preferably, the first rubber pad abuts against the front surface of the motherboard, and the second rubber pad abuts against the rear surface of the motherboard. The second rubber pad and the replacement sleeve contact the motherboard to ensure that the contact parts are connected by a flexible material, thereby improving the protection effect of the contact parts.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up an assistive component, the screws and the motherboard are in a state of non-direct contact when the user installs the motherboard. This reduces the problem of screws being inserted into the motherboard's pre-drilled holes and easily damaging the motherboard during installation, and further improves the safety of the motherboard during installation.

[0021] Please see Figures 1-5 This utility model provides a technical solution: an ultra-long high-frequency double-sided multi-layer antenna PCB board, including a motherboard 1, a terminal block 2 fixedly connected to the front surface of the motherboard 1, a resistor 3 fixedly connected to the surface of the motherboard 1, a control chip 4 fixedly connected to the surface of the motherboard 1, and an assisting component 5 set inside the mounting hole of the motherboard 1.

[0022] Specifically, the assisting component 5 includes a front sleeve 51, which is fixedly connected to the inner wall of the mounting hole of the main board 1. A knob 52 is rotatably connected to the inner wall of the front sleeve 51, and a guide ring 53 is fixedly connected to the inner wall of the front sleeve 51. A groove is provided on the surface of the knob 52, and the guide ring 53 is rotatably connected to the inner wall of the groove. A threaded rod 54 is fixedly connected to the rear surface of the knob 52, and a rear sleeve 55 is fixedly connected to the rear surface of the front sleeve 51. A locking threaded cylinder 56 is threadedly connected to the inner wall of the rear sleeve 55, and the threaded rod 54 is threadedly connected to the inner wall of the locking threaded cylinder 56.

[0023] In this embodiment, the user can rotate the threaded rod 54 via the knob 52 to ensure that the threaded rod 54 can engage with the locking threaded cylinder 56, thereby driving the locking threaded cylinder 56 to screw into the reserved mounting hole of the mounting structure.

[0024] Specifically, a first rubber pad 57 is fixedly connected to the rear surface of the protrusion of the front sleeve 51, and a second rubber pad 58 is fixedly connected to the front surface of the rear sleeve 55.

[0025] In this embodiment, the first rubber pad 57 can protect the contact area between the front sleeve 51 and the motherboard 1, thereby reducing the problem of the motherboard 1 being squeezed and damaged due to direct contact between the front sleeve 51 and the motherboard 1.

[0026] Specifically, a guide groove is provided on the outer circumference of the locking threaded cylinder 56. A force-carrying ring 59 is rotatably connected to the inner wall of the guide groove. The force-carrying ring 59 is slidably connected to the inner wall of the rear sleeve 55. A compression spring 510 is fixedly connected to the front surface of the force-carrying ring 59. The end of the compression spring 510 away from the force-carrying ring 59 is fixedly connected to the front inner wall of the front sleeve 51.

[0027] In this embodiment, the force ring 59 and the compression spring 510 work together to apply a certain thrust to the locking threaded cylinder 56 to ensure the stability of the locking threaded cylinder 56 in the locked state.

[0028] Specifically, the thickness of the rear sleeve 55 is greater than the thickness of the rear surface of the main board 1.

[0029] In this embodiment: the motherboard 1 can be supported by the rear sleeve 55 to ensure that there is sufficient gap between the back of the motherboard 1 and the outer casing for placing the motherboard 1.

[0030] Specifically, the first adhesive pad 57 abuts against the front surface of the motherboard 1, and the second adhesive pad 58 abuts against the rear surface of the motherboard 1.

[0031] In this embodiment: the second rubber pad 58 and the replacement sleeve 55 are in contact with the motherboard 1 to ensure that the contact part is connected by a flexible material, thereby improving the protection effect of the contact part.

[0032] Working principle: When assembling the antenna, insert the antenna cable connectors into the terminal block 2 in sequence, then install the main board 1 and the antenna cable into the housing. After installation, plug the power cord and signal cable into the reserved interface of the main board 1. The main board 1 is then powered on and works with the control chip 4 and the antenna cable to transmit signals.

[0033] When installing the mainboard 1, align the rear sleeve 55 with the pre-drilled mounting hole on the housing base, and then place the mainboard 1. As the rear sleeve 55 contacts the housing base, use a tool to rotate the knob 52 clockwise. The knob 52 rotates the threaded rod 54, which engages with the locking threaded cylinder 56 via threads. Simultaneously, the locking threaded cylinder 56 rotates with the assistance of the rear sleeve 55 and gradually unscrews the rear sleeve 55. As the locking threaded cylinder 56 unscrews the rear sleeve 55, it pulls the load-bearing ring 59. The load-bearing ring 59 moves in the specified direction and loses the pressure applied to the compression spring 510. 10. After the pressure is released, the screw gradually rebounds and, in conjunction with the load-bearing ring 59, applies pressure to the locking threaded cylinder 56. At the same time, the locking threaded cylinder 56 is gradually screwed into the mounting hole. When the locking threaded cylinder 56 is tightened, the remaining locking threaded cylinders 56 are tightened according to the above steps, and the motherboard 1 can be fixed on the housing base. By setting the assist component 5, the screw and the motherboard 1 are in a non-direct contact state when the user installs the motherboard 1. This reduces the problem of screws being inserted into the reserved holes of the motherboard 1 and easily damaging the motherboard 1 during the installation process, and further improves the safety of the motherboard 1 during the installation process.
