Technical Field
[0001] This utility model relates to the field of communication equipment technology, and in particular to a low-frequency vibrator. Background Technology
[0002] Existing low-frequency oscillators mostly adopt a hollow structure, which results in insufficient overall strength of the oscillator. After long-term use, the oscillator is prone to deformation, which greatly affects the working frequency range of the oscillator. Furthermore, due to the large number of flow channels during die casting production, a longer filling and molding time is required, resulting in low production efficiency.
[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a low-frequency oscillator to solve the problems of low die-casting production efficiency and poor structural stability caused by the large number of hollow structures in the existing low-frequency oscillators.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A low-frequency oscillator includes a balun base, the top of which is provided with four oscillator arms in a ring shape. Each oscillator arm is L-shaped, and each oscillator arm has a feed part connected to the balun base at its pointed end.
[0007] As described above, a low-frequency oscillator includes a first radiating arm, a second radiating arm, a first bent arm, and a second bent arm. One end of the first radiating arm and the second radiating arm are respectively connected to the feed section, and the first radiating arm and the second radiating arm are arranged perpendicularly to each other. The first bent arm extends and bends along the other end of the first radiating arm and is located on the side of the first radiating arm facing the balun seat. The second bent arm extends and bends along the other end of the second radiating arm and is located on the side of the second radiating arm facing the balun seat.
[0008] As described above, in a low-frequency oscillator, the first radiating arm, the second radiating arm, the first bent arm, and the second bent arm are all rectangular in shape.
[0009] As described above, a low-frequency oscillator has a first gap groove formed between two adjacent oscillator arms, and a second gap groove is provided on the balun seat corresponding to the first gap groove. The first gap groove and the second gap groove are connected.
[0010] As described above, in a low-frequency oscillator, a feeding groove is provided on the side of the feeding section near the center of the balun seat, a feeding connector is provided in the feeding groove, a feeding plate is provided in the feeding groove, and the feeding plate is electrically connected to the feeding connector.

[0013] As described above, in a low-frequency oscillator, the bottom of the balun seat is provided with at least two limiting posts.
[0014] Beneficial effects:
[0015] This utility model discloses a low-frequency oscillator, including a balun base. The top of the balun base is circularly equipped with four oscillator arms, each of which is L-shaped. This L-shaped structure reduces the number of unnecessary perforated structures and small crossbeams, shortening the time required for material filling and molding during die-casting production, and also ensures a stable structure that is less prone to deformation.

[0020] In the description of this utility model, it should be understood that the terms "top" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation" and "connection" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] like Figure 1-2 As shown in the embodiment of this application, a low-frequency oscillator is proposed, including a balun seat 1. The top of the balun seat 1 is provided with four oscillator arms 2 in a ring shape. Each oscillator arm 2 is L-shaped, and each oscillator arm 2 has a feed part 3 connected to the balun seat 1 on its pointed end.
[0022] This utility model discloses a low-frequency oscillator, including a balun base 1. The top of the balun base 1 is circumferentially equipped with four oscillator arms 2, each of which is L-shaped. This L-shaped structure reduces the number of unnecessary perforated structures and small crossbeams, shortening the time required for material filling and molding during die-casting production, and also ensures a stable structure that is not easily deformed. Furthermore, the four oscillator arms 2 form a cross structure around the balun base 1, reducing the impact of the low-frequency oscillator on the system. This low-frequency oscillator disclosed in this application reduces the number of unnecessary perforated structures and small crossbeams, improves the production efficiency of low-frequency oscillators, and ensures a stable structure that is not easily deformed.
[0023] The oscillator arm 2 includes a first radiating arm 21, a second radiating arm 22, a first bent arm 23, and a second bent arm 24. One end of the first radiating arm 21 and the second radiating arm 22 are respectively connected to the feed section 3, and the first radiating arm 21 and the second radiating arm 22 are arranged perpendicularly to each other. The first bent arm 23 extends and bends along the other end of the first radiating arm 21, and the first bent arm 23 is located on the side of the first radiating arm 21 facing the balun seat 1. The second bent arm 24 extends and bends along the other end of the second radiating arm 22, and the second bent arm 24 is located on the side of the second radiating arm 22 facing the balun seat 1. By bending the design, the effective length and current of the oscillator arm 2 are changed, thereby affecting its resonant frequency and radiation characteristics. The frequency band of this low-frequency oscillator is 806-960MHz, the standing wave ratio is less than 1.4, and the isolation is greater than 30dB. In addition, the rigidity and stability of the oscillator arm 2 are enhanced, and the impact of mechanical vibration on its performance is reduced.
[0024] The first radiating arm 21, the second radiating arm 22, the first bending arm 23 and the second bending arm 24 are all rectangular in shape. Compared with irregular shapes, cubes are easier to die-cast and reduce the occurrence of tip discharge.
[0025] A first gap groove 25 is formed between two adjacent oscillator arms 2, and a second gap groove 11 is provided on the balun seat 1 corresponding to the first gap groove 25. The first gap groove 25 and the second gap groove 11 are connected to each other, which effectively improves the oscillation effect of the oscillator arm 2, and through this setting, the low-frequency oscillator meets the requirements of lightweight.
[0026] The power supply section 3 has a power supply groove 31 on the side near the center of the balun seat 1. The power supply groove 31 has a power supply connector 32 and a power supply piece 33. The power supply piece 33 is electrically connected to the power supply connector 32. By setting the power supply groove 31, it is easy to connect the cable to the power supply connector 32, effectively increasing the connection area between the power supply section 3 and the cable, improving the stability of the cable connection, and thus forming a stable power supply structure. This power supply structure can produce a good excitation effect on the low-frequency oscillator.
[0027] The balun seat 1 and the four oscillator arms 2 are integrally formed. The low-frequency oscillator is obtained by die casting. The above method can make the overall weight of the low-frequency oscillator more uniform, shorten the molding time of the low-frequency oscillator, and effectively improve the production efficiency of the low-frequency oscillator.
[0028] The bottom of the balun base 1 is provided with mounting screw holes 12, which facilitates the installation of the low-frequency vibrator into the antenna and enables quick assembly and disassembly. The bottom of the balun base 1 is provided with at least two limiting posts 13 to facilitate the alignment and fixation of the low-frequency vibrator with the antenna.
