Description

Technical Field

[0001] This invention relates to the field of microwave signal technology, specifically to a tunable microwave signal generator. Background Technology

[0002] Microwave signal generators are indispensable core electronic devices in fields such as wireless communication, radar detection, electronic measurement, and radio frequency testing. The stability and accuracy of their output signal directly determine the overall system performance. Currently, most conventional tunable microwave signal generators on the market use a plug-in structure for their signal interfaces, relying solely on plug-in connections to establish signal line connections, lacking dedicated locking and limiting structures. Under conditions of long-term continuous operation, frequent cable plugging and unplugging, and on-site vibration and displacement, signal line connectors are prone to loosening, misalignment, and intermittent connections. Poor line contact directly causes microwave signal attenuation, waveform distortion, frequency drift, and signal interruption, severely affecting the accuracy of test data and the normal operation of the equipment. Furthermore, traditional interfaces cannot radially clamp or horizontally limit cables, resulting in poor anti-shake capabilities and limited applicability. In addition, some similar devices with added locking structures have complex structures, often using snap-fit ​​single-point fixation with limited locking range. Uneven force can easily cause cable damage, and disassembly and assembly are cumbersome, maintenance is inconvenient, and mechanical durability is insufficient, making it difficult to meet the requirements of high-precision, high-stability microwave signal transmission. Therefore, designing a tunable microwave signal generator with dual positioning and locking functions, reliable structure, and convenient operation has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0003] The purpose of this invention is to provide a tunable microwave signal generator to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a tunable microwave signal generator, comprising a device body, wherein an installation receiving groove is provided on the upper bottom surface of the device body, a control operation component is provided on the front side of the device body, and a signal tuning module and a cable locking and positioning component are also provided on the device body. A total of four cable locking and positioning components are provided, each cable locking and positioning component including a signal input base, one end of the signal input base being provided with a radial clamping mechanism, and one end of the radial clamping mechanism being provided with a horizontal limiting mechanism.

[0005] As a preferred embodiment of the present invention, the radial clamping mechanism includes two supporting swing arms, which are symmetrically distributed. Each supporting swing arm is movably connected to a transmission link. The two symmetrically arranged transmission links are movably connected through an upper linkage frame. The bottom ends of the two supporting swing arms are movably connected through a lower fixed frame. A circular hole is provided between the upper linkage frame and the lower fixed frame, and a lifting adjustment rod is connected through the circular hole provided in the upper linkage frame and the lower fixed frame.

[0006] As a preferred embodiment of the present invention, the supporting swing arm includes a first arm body and a second arm body, both ends of the first arm body and the second arm body are provided with hinged ends, and a cylindrical ring is connected to the hinged end of one end of the first arm body and the second arm body.

[0007] As a preferred embodiment of the present invention, the first arm and the second arm have the same shape, and a circular hole is provided in the middle section of the first arm and the second arm.

[0008] As a preferred embodiment of the present invention, the transmission link includes a link body, and one end of the link body is provided with a connecting end.

[0009] As a preferred embodiment of the present invention, the horizontal limiting mechanism is provided with a limiting base, the limiting bases are symmetrically arranged, the limiting bases are fixedly connected to a rotating support, and a rotating adjustment component is movably connected to the rotating support. The rotating adjustment component is movably engaged with an elastic locking assembly.

[0010] As a preferred embodiment of the present invention, the rotating adjustment component includes a slotted cylindrical body and a hinged connecting arm, wherein the slotted cylindrical body and the hinged connecting arm are movably connected.

[0011] As a preferred embodiment of the present invention, the slotted cylindrical body is a cylinder with notches and grooves, and the slotted cylindrical body has a total of six notches and grooves distributed in a ring.

[0012] As a preferred embodiment of the present invention, the elastic locking assembly includes a concave elastic flexible plate and positioning metal locking balls. The concave elastic flexible plate is a U-shaped flexible plate, and the positioning metal locking balls are metal balls. A total of three positioning metal locking balls are provided, and the three positioning metal locking balls are evenly distributed on the concave elastic flexible plate at intervals.

[0013] Compared with the prior art, the beneficial effects of the present invention are: A tunable microwave signal generator employs a linkage-type radial clamping structure, which can achieve omnidirectional clamping and locking of the connected microwave signal line, effectively filling the assembly gap between the cable and the interface, and completely improving the defects of loose wire ends and poor contact after long-term use of traditional plug-in structures. This structure provides uniform and controllable clamping force, preventing squeezing damage to the cable sheath and core, significantly improving the stability of the signal line connection, and avoiding signal disconnection and increased transmission loss caused by poor contact from the source, thus ensuring the basic transmission quality of microwave signals.

[0014] A tunable microwave signal generator is equipped with an independent horizontal limiting mechanism. Through the cooperation of a rotating component with a notched groove and an elastic locking component, it can precisely limit the horizontal deviation and swaying of the signal line. Under conditions of equipment debugging, movement, or vibration in the field, it can maintain the cable position at all times, preventing interface wear and connection failure caused by repeated cable swinging, improving the device's adaptability to complex working environments, and extending the overall service life of the signal interface and its supporting cables.

[0015] A tunable microwave signal generator features a purely mechanical linkage structure, requiring no additional circuitry, pneumatic, or hydraulic auxiliary components. Its simple and compact design makes assembly and maintenance easy. Operators only need to pull the adjusting rod and rotate the adjusting component to lock and position the cable; the operation is simple, intuitive, and easy to learn. Furthermore, the mechanical components have a low failure rate, are resistant to high temperatures and electromagnetic interference, and are fully compatible with the working environment of microwave equipment, reducing subsequent maintenance and repair costs.

[0016] A tunable microwave signal generator employs a dual positioning method combining radial clamping and horizontal limiting to achieve multi-dimensional fixation of the signal line. This effectively ensures the stability of the microwave signal transmission path and prevents adverse phenomena such as waveform distortion, frequency deviation, and amplitude fluctuation. For applications with stringent requirements for microwave signal quality, such as high-precision testing, communication, and radar, it can continuously output standard and stable microwave signals, significantly improving the overall working accuracy and reliability of the device.

[0017] A tunable microwave signal generator integrates clamping and limiting functions into a single component. The four sets of locking and positioning components are rationally arranged, maximizing space utilization and avoiding additional internal or external installation space requirements. The various transmission and locking components exhibit high precision and smooth, continuous operation, meeting the needs of repeated cable insertion and removal and locking, and demonstrating excellent wear resistance. The overall structure is highly versatile, adaptable to microwave signal cables of different specifications, thus broadening the device's practical application range. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Please refer to Figure 1-8 A tunable microwave signal generator includes a device body 1, with an installation receiving groove 3 on the upper bottom surface of the device body 1. A control operation component 2 is provided on the front of the device body 1. The device body 1 is also provided with a signal tuning module 4 and a cable locking and positioning component 5. There are four cable locking and positioning components 5 in total. Each cable locking and positioning component 5 includes a signal input base 51. One end of the signal input base 51 is provided with a radial clamping mechanism 52, and one end of the radial clamping mechanism 52 is provided with a horizontal limiting mechanism 53.

[0022] The radial clamping mechanism 52 includes two support swing arms 521. The two support swing arms 521 are symmetrically distributed. Each support swing arm 521 is movably connected to a transmission link 522. The two symmetrically arranged transmission links 522 are movably connected to each other through an upper linkage frame 523. The bottom ends of the two support swing arms 521 are movably connected through a lower fixed frame 524. A circular hole is opened between the upper linkage frame 523 and the lower fixed frame 524. A lifting adjustment rod 525 is connected through the circular hole opened in the upper linkage frame 523 and the lower fixed frame 524.

[0023] The support arm 521 includes a first arm body 5211 and a second arm body 5212. Both ends of the first arm body 5211 and the second arm body 5212 are provided with hinge ends 5213. A cylindrical ring is also connected to the hinge end 5213 at one end of the first arm body 5211 and the second arm body 5212.

[0024] The first arm body 5211 and the second arm body 5212 have the same shape, and a circular hole is also provided in the middle section of the first arm body 5211 and the second arm body 5212.

[0025] The transmission link 522 includes a link body 5221, and one end of the link body 5221 is provided with a connecting end 5223.

[0026] The horizontal limiting mechanism 53 is provided with a limiting base 531. The limiting base 531 is symmetrically arranged. The limiting base 531 is fixedly connected to the rotating support 532. The rotating support 532 is movably connected to a rotating adjustment component 533. The rotating adjustment component 533 is movably engaged with an elastic locking component 534.

[0027] The rotary adjustment component 533 includes a slotted cylindrical body 5331 and a hinged connecting arm 5332, which are movably connected.

[0028] The slotted cylindrical body 5331 is a cylinder with notches and slots. The slotted cylindrical body 5331 has a total of six notches and slots, which are distributed in a ring.

[0029] The elastic locking assembly 534 includes a concave elastic flexible plate 5341 and positioning metal locking balls 5342. The concave elastic flexible plate 5341 is a U-shaped flexible plate, and the positioning metal locking balls 5342 are metal balls. There are three positioning metal locking balls 5342, which are evenly distributed on the concave elastic flexible plate 5341.

[0030] The working principle of this invention is as follows: In practical use, the external microwave signal cable is first plugged into the signal access socket 51 to complete the initial connection. The operator then pulls the adjusting rod 525 upwards. The adjusting rod 525 moves axially upwards along the coaxial circular hole between the upper linkage frame 523 and the lower fixed frame 524, simultaneously driving the upper linkage frame 523 to move upwards. During the lifting and lowering process, the upper linkage frame 523 generates a pulling force on the transmission links 522 hinged at both ends, causing the transmission links 522 to rotate around their hinge point with the support swing arm 521. The two symmetrically distributed transmission links 522 move synchronously, thereby pulling the corresponding support swing arm 521 to swing inward around its hinge point with the lower fixed frame 524. The two sets of support swing arms 521 simultaneously clamp inward, radially locking the inserted signal cable post, eliminating insertion gaps, and achieving radial fixation of the signal cable, preventing radial loosening of the cable. After radial clamping is completed, the operator manually moves the rotating adjustment component 533, causing it to rotate around the rotating support 532. This rotates the annular notch on the outer wall of the slotted cylindrical body 5331 of the slotted cylindrical component precisely with the metal positioning ball 5342 on the elastic engaging component 534. The concave flexible plate 5341 has elastic deformation capability and undergoes adaptive deformation under assembly force, causing the three metal positioning balls 5342 to engage with the notch in the slotted cylindrical body 5331 of the slotted cylindrical component. The position of the elastic engaging component 534 is locked by the snap-fit ​​engagement. Two sets of symmetrically arranged horizontal limiting mechanisms 53 work together to precisely limit the horizontal displacement range of the cable, achieving overall horizontal positioning of the cable. This invention, through a dual mechanical locking structure of radial clamping and horizontal limiting, completely solves the problems of unstable plugging and loose contact after long-term use of signal lines, ensuring continuous and stable microwave signal transmission, effectively avoiding faults such as microwave signal waveform distortion, amplitude fluctuation, and frequency offset caused by poor line contact, and ensuring the output performance of the tunable microwave signal generator.
