Description

Technical Field

[0001] This invention relates to the field of impedance adjustment technology, specifically to a fault-proof impedance conversion structure and impedance adjustment device. Background Technology

[0002] Impedance regulation technology has wide applications in many fields such as power systems and electronic equipment. By adjusting the impedance of a system or device, various functions can be achieved, including power matching, signal transmission optimization, and improved system stability. Currently, common impedance regulation methods often use switching elements to combine components with different impedance values ​​to achieve the desired impedance.

[0003] However, in actual impedance regulation processes, it is impossible to guarantee that errors will not occur during each switching operation. On the one hand, traditional switching control logic is relatively simple, and when faced with complex operating conditions and electromagnetic interference, it is prone to mis-triggered control signals, leading to incorrect switching of switching elements. For example, in power systems, when voltage fluctuations or harmonic interference occur in the power grid, the switching switch may receive incorrect control commands, switching on or off the wrong impedance element, thus affecting the normal operation of the entire system. On the other hand, existing switching equipment lacks effective monitoring and feedback mechanisms, making it difficult to detect errors or incomplete switching in a timely manner. This not only reduces the accuracy and reliability of impedance regulation but may also trigger a series of serious problems such as equipment failure and system instability, posing significant hidden dangers to applications in related fields.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0022] Example 1:

[0023] See Figure 1As shown, this embodiment provides a fault-prevention impedance conversion structure, which is used to monitor and provide feedback on the actual position of the switching blade 120 during the switching process to avoid incorrect switching or incomplete switching. Specifically, it includes: a conversion component 100, which includes a switching blade 120, the switching blade 120 being rotatable around a rotation center line 1001, the rotation center line 1001 being located at one end of the switching blade 120, and a pressure block 123 at the other end of the switching blade 120; and a monitoring component 200, the... The monitoring component 200 includes two monitoring switches 210, which are respectively disposed on both sides of the conversion blade 120. Each monitoring switch 210 includes a body 211, a central control module, and at least one roller 212. At least one roller 212 is disposed on the side of the body 211 facing the conversion blade 120. The pressure block 123 can squeeze the roller 212 to drive the body 211 to move. The central control module is connected to the body 211 to output the position signal of the conversion blade 120.

[0024] The error-proof impedance conversion structure of this utility model achieves switching between different impedances through the rotation of the switching blade 120. During this process, two monitoring switches 210 can monitor and provide feedback on the different switching directions of the switching blade 120 to ensure the switching effect of the switching blade 120 and avoid erroneous switching or incomplete switching that is prone to occur in conventional operations, thereby achieving the purpose of error-proof impedance conversion. Compared with conventional conversion technologies at present, this application has the advantages of flexible use, high monitoring accuracy, fast response speed, perfect monitoring and feedback mechanism, and wide application range, and has broad application prospects in this industry.

[0025] It should be noted that, for ease of description, in this embodiment, the length direction of the error-proof impedance conversion structure is defined as the first direction X, the width direction of the error-proof impedance conversion structure is defined as the second direction Y, and the height direction of the error-proof impedance conversion structure is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0026] In this embodiment, the conversion component 100 is connected to a resistor to achieve switching between different impedances through the rotation of the conversion blade 120. By switching the resistor through the rotation of the conversion blade 120, the complex impedance adjustment operation is transformed into a simple mechanical rotation action, thus facilitating manual operation and coordination with the automated control unit. Further, the conversion blade 120 includes a pressure block 123, a handle 121, and a blade body 122. One end of the blade body 122 rotates around the rotation center line 1001, and the other end is connected to the handle 121. The pressure block 123 is disposed between the blade body 122 and the handle 121. The design of the blade body 122 rotating around the rotation center line 1001 ensures that its conductive portion contacts the connection port 130 on the resistor connector according to a predetermined trajectory and sequence, achieving precise resistance switching. The handle 121 provides a convenient point of force application for the operator, making the rotation of the blade 122 easier and less strenuous. The handle 121 is typically made of insulating material and its structural design maintains a safe distance from the conductive parts of the blade 122, effectively preventing electric shock accidents during operation and enhancing operational safety. The pressure block 123 cooperates with the roller 212 in the monitoring component 200 to transmit the position of the switching blade 120.

[0027] See Figure 1 As shown, the conversion assembly 100 includes a central fixing member 110, which includes a first fixing platform 111 and a rotating shaft 112. The rotating shaft 112 is disposed on the first fixing platform 111, and its axis coincides with the rotation center line 1001. The conversion blade 120 is rotatably connected to the rotating shaft 112. Specifically, the axis of the rotating shaft 112 coincides with the rotation center line 1001, ensuring that the blade body 122 maintains a precise circular motion trajectory during rotation. This design eliminates switching deviations caused by eccentricity, allowing the conductive part of the blade body 122 to be precisely aligned with the connection port 130 to achieve electrical connection with the resistor.

[0028] Furthermore, in this embodiment, the blade body 122 has a sliding groove inside. The sliding groove is located at the center of the blade body 122 and extends along the length direction of the blade body 122. The rotating shaft 112 in the conversion assembly 100 passes through the sliding groove and can move along the sliding groove, thereby achieving the purpose of rotating the blade body 122 around the rotation center line 1001. In different embodiments, the rotational connection between the blade body 122 and the rotating shaft 112 can also be achieved by other structures, and this utility model does not impose specific limitations on this.

[0029] Furthermore, any of the connection ports 130 in this embodiment includes a second fixed platform 131 and at least two limiting blocks 132. The at least two limiting blocks 132 are arranged at intervals along the second direction Y to form a guide groove extending along the first direction X. The conversion blade 120 can be embedded in the guide groove to correct the rotation direction of the conversion blade 120. Specifically, the guide groove extends along the first direction X, and the conversion blade 120 can be embedded therein. During the rotation of the conversion blade 120, the limiting blocks 132 on both sides of the guide groove can effectively limit its offset in the second direction Y, so that the conversion blade 120 rotates strictly according to the preset path, ensuring that the conductive part of the blade body 122 accurately connects to the resistor connection port 130, thereby improving the accuracy of impedance switching.

[0030] In this embodiment, the connection port 130 further includes at least two adjusting fasteners 133, each corresponding to one of the at least two limiting blocks 132. The limiting blocks 132 are detachably connected to the second fixed platform 131 via the adjusting fasteners 133 to adjust the width of the guide groove. Therefore, by detachably connecting the limiting blocks 132 to the second fixed platform 131 via the adjusting fasteners 133, the width of the guide groove can be easily adjusted. This allows the connection port 130 to accommodate different sizes and specifications of the converter blades 120, enhancing the versatility and flexibility of the conversion assembly 100. When upgrading the product or replacing different models of converter blades 120, it is not necessary to replace the entire connection port 130; only the width of the guide groove needs to be adjusted, reducing the upgrade cost and maintenance difficulty of the equipment.

[0031] In this embodiment, the monitoring component 200 is used to monitor the position of the conversion blade 120 to ensure that it can rotate into position. Specifically, the monitoring switch 210 further includes at least one extension plate 213, which is disposed between the body 211 and the roller 212. One end of the extension plate 213 is connected to the body 211, and the other end extends perpendicularly to the body 211 and is connected to the roller 212, so that the roller 212 is located on the moving path of the pressure block 123. The extension plate 213 positions the roller 212 on the moving path of the pressure block 123, allowing the roller 212 to directly sense changes in the position of the pressure block 123. When the conversion blade 120 rotates, the pressure block 123 moves with the blade body 122. Once the pressure block 123 contacts the roller 212, the roller 212 triggers the central control module in the monitoring switch 210, thereby accurately determining whether the conversion blade 120 has rotated into position. Specifically, the central control module in this embodiment is preferably a PLC controller. Compared to indirect monitoring methods, this design, which directly monitors the movement path of the pressure block 123, avoids inaccurate monitoring caused by errors in intermediate links, greatly improving monitoring accuracy. This ensures that the converter blade 120 accurately connects to the corresponding resistor during each impedance switch, guaranteeing accurate impedance adjustment. The contact design between the roller 212 and the pressure block 123 allows even minimal displacement changes to trigger the monitoring switch 210. Because the roller 212 can rotate freely, slight movements of the pressure block 123 can cause the roller 212 to roll, quickly transmitting position information to the central control module connected to the monitoring switch 210. In high-frequency impedance switching scenarios, such as when communication equipment adjusts impedance in real time based on signal strength, this highly sensitive monitoring feedback can promptly capture the position of the converter blade 120, providing accurate signals to the control unit, enabling rapid system response and ensuring stable equipment operation. The extension plate 213 allows for flexible adjustment of the roller 212's position on the movement path of the pressure block 123 according to actual needs. In impedance adjustment devices of different models or specifications, the structural dimensions of the conversion blade 120 and the pressure block 123 may differ. By adjusting the installation angle or position of the extension plate 213, the monitoring component 200 can be adapted to different devices, thereby enhancing the versatility and adaptability of the monitoring component 200.

[0032] Furthermore, the monitoring component 200 also includes a display connected to the central control module to provide feedback on the position signal of the switching blade 120 for operator observation.

[0033] Example 2:

[0034] See Figure 2 and Figure 3As shown, this embodiment provides an impedance adjustment device, which includes a housing 300, multiple resistors, and multiple error-proof impedance conversion structures as described in Embodiment 1. The error-proof impedance conversion structures are disposed inside the housing 300 and are respectively connected to the multiple resistors.

[0035] In summary, the error-proof impedance conversion structure of this utility model achieves switching between different impedances through the rotation of the switching blade 120. During this process, two monitoring switches 210 can monitor and provide feedback on the different switching directions of the switching blade 120 to ensure the switching effect of the switching blade 120 and avoid erroneous switching or incomplete switching that is prone to occur during conventional operations, thereby achieving the purpose of error-proof impedance conversion. Compared with conventional conversion technologies at present, this application has the advantages of flexible use, high monitoring accuracy, fast response speed, perfect monitoring and feedback mechanism, and wide application range, and has broad application prospects in this industry.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
