[0002] With the development of communication technology, antennas, as one of the components of communication networks, are responsible for the input and output of wireless signals. The vibrator is the core component of the antenna, which enhances the antenna's wireless signal transmission capability. In the future, antennas will need to meet the diverse needs of different application scenarios, and antenna vibrators will also become more diversified.

[0003] Currently, there are many types of base station antennas, and the demand is large. The reliability and cost control of the vibrators need to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a low-frequency radiation unit mounting support, which solves the problems of the current base station antennas being diverse in type and in large quantity, and the need to improve the reliability and cost control of the vibrators.

[0005] This utility model provides the following technical solution: a low-frequency radiation unit mounting support, including a vibrator radiation surface, a first limiting groove is evenly opened around the top of the vibrator radiation surface, a second limiting groove is opened on the side of the first limiting groove, and a central through hole is opened in the middle of the vibrator radiation surface.

[0006] Two third limiting slots are symmetrically opened on one side of the central through hole, and two limiting through holes are symmetrically opened on the other side of the central through hole. A bottom support assembly is provided at the bottom of the oscillator radiation surface. Two cable bodies are symmetrically inserted into the bottom support assembly. The top ends of the cable bodies pass through the limiting through holes. Feed plates are provided on the sides of the two cable bodies. The feed plates pass through the third limiting slots. The top ends of the feed plates are passed through by the top ends of the cable bodies. A PCB base plate is provided at the bottom of the bottom support assembly. The bottom ends of the feed plates are inserted into the PCB base plate, and the bottom ends of the cable bodies are inserted into the PCB base plate.

[0007] Preferred technical solution 1: The bottom support assembly includes a bottom support frame disposed at the bottom of the oscillator radiation surface, two cable limiting cylinders are disposed in the middle of the bottom support frame, the cable body passes through the middle of the cable limiting cylinder, and top clamping plates are evenly disposed around the top of the bottom support frame.

[0015] Compared with the prior art, the present invention provides a low-frequency radiation unit mounting support, which has the following advantages:

[0016] (1) This utility model is provided with a vibrator radiating surface, a bottom support assembly, a cable body, a feed plate and a PCB base plate. The bottom support assembly connects the vibrator radiating surface to the cable body, the feed plate and the PCB base plate. This can reduce the cost of the vibrator while ensuring its reliable stability, thereby reducing the cost of the entire antenna. In addition, installing the vibrator with the bottom support assembly has a better improvement in antenna intermodulation and antenna intermodulation stability. The bottom support assembly is designed with top clamps at the top and bottom to improve the portability of the vibrator installation and reduce the installation cost.

[0024] Please see Figure 1-5 ,

[0025] Example 1: A low-frequency radiation unit mounting support includes a vibrator radiation surface 1, a first limiting groove 2 is evenly provided around the top of the vibrator radiation surface 1, a second limiting groove 3 is provided on the side of the first limiting groove 2, and a central through hole 4 is provided in the middle of the vibrator radiation surface 1.

[0026] Two third limiting slots 5 are symmetrically opened on one side of the central through hole 4, and two limiting through holes 6 are symmetrically opened on the other side of the central through hole 4. A bottom support component 7 is provided at the bottom of the oscillator radiation surface 1. Two cable bodies 8 are symmetrically inserted on the bottom support component 7. The top of each cable body 8 passes through the limiting through hole 6. Feed plates 9 are provided on the sides of both cable bodies 8.

[0027] All power feeders 9 pass through the third limiting slot 5, and the top of each power feeder 9 is penetrated by the top of the cable body 8. The bottom of the bottom support component 7 is provided with a PCB base plate 10, and the bottom of each power feeder 9 is inserted into the PCB base plate 10. The bottom of each cable body 8 is also inserted into the PCB base plate 10.

[0028] The bottom support assembly 7 includes a bottom support frame 701 disposed at the bottom of the oscillator radiation surface 1. Two cable limiting cylinders 702 are disposed in the middle of the bottom support frame 701. The cable bodies 8 pass through the middle of the cable limiting cylinders 702. Top plates 703 are evenly disposed around the top of the bottom support frame 701. Limiting contact blocks 704 are disposed on the sides of the top plates 703. The top of the top plates 703 passes through the first limiting slot 2. The top of the limiting contact blocks 704 passes through the second limiting slot 3.

[0029] Example 2: The difference between this example and Example 1 is that the bottom side of the top plate 703 is curved.

[0030] This allows the top plate 703 to engage better with the first limiting slot 2 when it passes through it.

[0031] Example 3: The difference between this example and Example 1 is that the two feed plates 9 are arranged in a cross manner, and both feed plates 9 penetrate the bottom of the bottom support frame 701.

[0032] This makes the connection between the two feed plates 9 and the cable body 8 more stable.

[0033] Example 4: The difference between this example and Example 1 is that two slots are symmetrically opened on both sides of the PCB base plate 10, and two blocks are symmetrically arranged on both sides of the bottom end of the bottom support frame 701, with the blocks inserted into the slots.

[0034] This makes the connection between the PCB base plate 10 and the bottom support frame 701 more stable.

[0035] In this embodiment, due to the wide variety of base station antennas and the large demand, the reliability and cost control of the vibrator need to be improved.

[0036] In summary, in practical implementation, when the user needs to connect the oscillator radiating surface 1 to the PCB base plate 10 through the cable body 8 and the power supply plate 9, the user first needs to place the oscillator radiating surface 1 at the top of the bottom support frame 701 in the bottom support assembly 7, so that the top clamping plate 703 and the limiting contact block 704 evenly arranged on the top of the bottom support frame 701 pass through the first limiting slot 2 and the second limiting slot 3 opened on the oscillator radiating surface 1, so that the top clamping plate 703 is clamped on the first limiting slot 2, and the limiting contact block 704 passes through the second limiting slot 3, so that the oscillator radiating surface 1 is stably connected to the top of the bottom support frame 701.

[0037] Before installing the oscillator radiating surface 1, the user needs to pass the two cable bodies 8 through the cable limiting tube 702 in sequence. The bottom end of the cable body 8 is connected to the PCB base plate 10 set at the bottom of the bottom support frame 701, while the top end of the cable body 8 passes through the limiting through hole 6. The feed plate 9 passes through the third limiting slot 5 and is inserted into the bottom support frame 701. It is then inserted into the PCB base plate 10 through the bottom support frame 701. The top end of the cable body 8 passes through the bottom of the feed plate 9, thus completely connecting the oscillator radiating surface 1 and the PCB base plate 10. This connection method is simpler and more convenient to operate, uses less material, can greatly reduce the cost of use, and also greatly improves stability, making it more convenient for users to use.
