[0027] In order for those skilled in the art to better understand the scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0028] In order to solve the problem of low replacement efficiency of the blocking and capacitive element in the related art, which affects the debugging efficiency, the present application provides a blocking and capacitive element replacement tool.

[0029] As Figure 1 and Figure 2As shown, the resistor-capacitor replacement tool comprises a seat body 10, a support assembly 20, a signal transmission device 40 and a traction assembly. The seat body 10 has a recess 11 for mounting a resistor-capacitor, and the seat body 10 is connected with the support assembly 20 to be mounted on a board card 30 through the support assembly 20. The signal transmission device 40 comprises a transmission body 41, a first conductive part 42 and a second conductive part 43, the first conductive part 42 is connected with the second conductive part 43 through the transmission body 41, the first conductive part 42 is electrically connected with the board card 30, and the second conductive part 43 is arranged on the groove wall of the recess 11 to contact with the resistor-capacitor. The traction assembly comprises an adjusting structure and a traction member 50 connected with each other, at least part of the adjusting structure is movably arranged to drive the traction member 50 to stretch and contract. The traction member 50 has a stretched state and a contracted state, when the traction member 50 is in the stretched state, the traction member 50 is located above the recess 11 to shield at least part of the opening of the recess 11, and when the traction member 50 is in the contracted state, the resistor-capacitor can be mounted into the recess 11 through the opening of the recess 11 to contact with the second conductive part 43.

[0030] By the ingenious design of the traction assembly, the replacement of the resistor-capacitor can be quickly completed without any tool. When the traction member 50 is in the stretched state, it shields part of the opening of the recess 11 to create a stable space for placing a new resistor-capacitor. Once the resistor-capacitor is in place, the adjusting structure drives the traction member 50 to move to the contracted state to mount the resistor-capacitor into the recess. The second conductive part 43 is in close contact with the resistor-capacitor to form a good electrical connection. In this way, the above process greatly simplifies the replacement steps of the resistor-capacitor, thereby solving the problem of low replacement efficiency of the resistor-capacitor in the related art, avoiding the cumbersome and time-consuming use of traditional welding tools, and enabling hardware engineers to quickly and conveniently perform signal debugging, effectively improving work efficiency and debugging accuracy. At the same time, the above arrangement of the signal transmission device 40 ensures the signal transmission quality between the resistor-capacitor and the board card 30, the first conductive part 42 is electrically connected with the board card 30, the second conductive part 43 is arranged on the groove wall of the recess 11 and contacts with the resistor-capacitor, and the transmission body 41 connects the two to form a stable signal path. The above design effectively avoids signal reflection caused by right-angle wiring, significantly reduces signal distortion, and improves signal integrity and accuracy.

[0031] In this embodiment, the cooperation of the seat body 10 and the support assembly 20 ensures the stability and electrical isolation of the replacement tool in the high-density PCB layout environment, avoiding the risk of short circuit and providing a safe guarantee for debugging work.

[0032] In the embodiment, the traction member 50 is a rope. In this way, the above arrangement can significantly reduce the complexity and volume of the overall tool, making it more portable and easier to carry. In addition, the rope is a relatively low-cost component, and using the rope as the key moving component can effectively reduce the manufacturing cost and improve the economy of the tool compared to other possible precision mechanical structures. At the same time, the above design choice not only meets the demand for portability in on-site debugging, but also makes the rapid replacement tool for the blocking and capacitive component more easily popularized and applied.

[0033] Specifically, the blocking and capacitive component can be easily put into or taken out of the groove 11 by manually stretching the rope without the need for complex mechanical devices. The flexibility and stretchability of the rope enable it to flexibly adapt to various replacement needs of the blocking and capacitive component, and the operation is simple and fast.

[0034] In the embodiment, the adjustment structure includes two clamping structures and a driving device, the two clamping structures respectively clamping two ends of the traction member 50, and the driving device being drivingly connected with the two clamping structures to drive the two clamping structures to move towards or away from each other to switch the traction member 50 between the stretched state and the contracted state. In this way, the two clamping structures respectively fix the two ends of the traction member 50, and the stretching and contracting state of the traction member 50 can be accurately controlled through the movement of the driving device, thereby adjusting the opening size of the groove 11. When replacing the blocking and capacitive component, the driving device causes the two clamping structures to move towards each other to release the traction member 50, so that it naturally contracts to put the blocking and capacitive component into the groove, thereby stably clamping the blocking and capacitive component to achieve good contact with the second conductive part 43; after the replacement of the blocking and capacitive component is completed, the driving device pushes the two clamping structures away from each other, so that the traction member 50 is in the stretched state to expand the opening of the groove, facilitating the putting in or taking out of the blocking and capacitive component.

[0035] Specifically, through the linkage of the driving device and the clamping structure, semi-automation or automation of the blocking and capacitive component replacement operation can be achieved, reducing the complexity and difficulty of manual operation. The operator only needs to simply control the driving device to complete the switching of the state of the traction member 50, without the need for additional tools or complex manual operation process, making the replacement of the blocking and capacitive component more easy and fast.

[0036] Optionally, the driving device is a manual trigger, an electric motor drive or other forms of automatic control mechanism to adapt to the needs of different scenes and operating environments, further improving the flexibility and operation convenience of the tool.

[0037] Optionally, the normal projection of the traction member 50 in the groove 11 coincides with the longitudinal neutral plane of the groove 11 when the traction member 50 is in the stretched state. In this way, the normal projection of the traction member 50 in the stretched state coincides with the longitudinal neutral plane of the groove 11 to ensure more uniform and reliable contact of the resistance-capacitance member with the second conductive part 43 during replacement. Because the stretching and contraction movements of the traction member 50 follow a straight trajectory, the transverse stress on the resistance-capacitance member is reduced, avoiding unstable electrical connection caused by uneven contact point pressure distribution, thereby optimizing the impedance characteristics of the signal transmission path and improving signal quality.

[0038] Optionally, the transmission body 41 is made of an elastic conductive material; and / or, the transmission body 41 is one; or, the transmission body 41 is multiple, and the multiple transmission bodies 41 are arranged at intervals along the preset direction. In this way, the transmission body 41 made of an elastic conductive material can deform when subjected to external force and then quickly recover to its original state, thereby ensuring that the transmission body 41 can compensate for minor positional deviations during replacement of the resistance-capacitance member through its own elastic deformation, always maintaining close contact with the resistance-capacitance member and the solder joints of the board 30, thereby ensuring the continuity and stability of signal transmission. In addition, the elastic material can also absorb part of the mechanical vibration, reducing the influence of external interference on electrical connection, and enhancing the adaptability of the tool in unstable environments. At the same time, the design of a single or multiple transmission bodies 41 optimizes signal transmission efficiency and debugging flexibility: when the transmission body 41 is designed as a single one, the entire signal path is simple and clear, reducing signal attenuation and distortion during transmission, which is suitable for scenarios with high signal frequency and strict requirements on transmission quality. The interval arrangement of multiple transmission bodies 41 not only provides stronger electrical connection capability, but also can adapt to different sizes and shapes of resistance-capacitance members, increasing the versatility and flexibility of debugging of the tool. The parallel design of multiple transmission bodies 41 ensures that even if one of the connection points fails, the other transmission paths can still ensure normal signal transmission, greatly improving the robustness and reliability of the system during complex debugging.

[0039] In the present embodiment, the transmission body 41 is two, and the two transmission bodies 41 are arranged at intervals along the preset direction. Among them, the second conductive part 43 is two, and the two second conductive parts 43 are respectively located on both sides of the resistance-capacitance member and are in contact with the resistance-capacitance member.

[0040] As Figure 1As shown, the support assembly 20 includes a support structure 21, the first end of which is connected to the base 10, and the second end of which overlaps the board 30. There may be a single support structure 21, or multiple support structures 21 spaced apart around the base 10. When multiple support structures 21 are spaced apart around the base 10, the multi-point support structure significantly enhances the stability and balance of the tool during tool replacement on high-density PCBs. Even in complex debugging environments, this reduces tool shaking or slipping caused by center of gravity shift or external interference, ensuring precise and safe operation. Furthermore, the distributed design of multiple support structures 21 allows the tool to accommodate boards 30 of varying sizes and shapes, broadening the tool's application range and improving its adaptability to a variety of applications.

[0041] Specifically, the first end of the support structure 21 is connected to the base 10, and the second end is overlapped on the board 30. Whether one or multiple support structures 21 are provided, stable contact between the base 10 and the board 30 is ensured. In particular, the provision of multiple support structures 21 evenly distributes the supporting force, avoiding the excessive local stress on the board 30 that may be caused by single-point support, reducing the risk of solder joint damage or board deformation, thereby protecting the integrity of the board 30 and extending its service life.

[0042] Optionally, the support structure 21 is rod-shaped, and the first end of the support structure 21 is spherically hinged to the base 10; and / or, an anti-slip portion is provided on the second end of the support structure 21. In this way, the above-mentioned spherical hinge setting allows the support structure 21 to rotate freely relative to the base 10, so that the support rod can flexibly adjust its angle in three-dimensional space to adapt to the surface of the board 30 with different inclinations and curvatures, thereby improving the adaptability of the tool when facing complex PCB layouts, ensuring that even on uneven or obstructed surfaces, the tool can be firmly placed without affecting its function. The spherical hinge can also absorb slight misalignment during the installation process, reducing the impact of operational errors on the stability of the entire system. At the same time, providing an anti-slip portion at the second end of the support structure 21 can significantly increase the friction coefficient of the contact surface, preventing the tool from sliding during operation or under the influence of external vibration, and avoiding signal path damage or debugging component position displacement caused by sliding.

[0043] In this embodiment, the support structure 21 is rod-shaped and an anti-slip portion is provided on the second end of the support structure 21 .

[0044] Optionally, the anti-slip portion is an anti-slip groove, or is covered with a soft elastic material, or is a magnetic device. A suitable anti-slip strategy is selected according to the specific application scenario to achieve the best fixing effect.

[0045] In the embodiment, the seat body 10 is a hexahedron, and at least one support structure 21 is arranged on each of the four bottom corners of the hexahedron, and at least one support structure 21 is arranged on each of the two larger-area and oppositely arranged sides of the four sides of the hexahedron. In this way, the support structures 21 of the bottom corners and the sides of the hexahedron are distributed, providing stable and balanced contact points between the tool and the PCB, thereby ensuring that the tool can be stably placed in any orientation, even if it faces an inclined, curved or irregular board surface, and through the combined action of the bottom corner and side support, the balance of the tool can be maintained. Especially the presence of side support can effectively resist the lateral force applied by the operator, reducing the risk of tool tilting or overturning, ensuring the safety and smoothness of the debugging process.

[0046] Specifically, the support structures 21 of the bottom corners and the sides of the seat body 10 not only provide mechanical stable support for the tool, but also avoid excessive wear of a single support point by dispersing the stress on the bottom of the seat body 10, thereby prolonging the overall service life of the tool. In addition, the above design also provides additional space for wiring, ventilation and heat dissipation, which helps to maintain the long-term operating performance of the tool.

[0047] In the embodiment, when the resistance-capacitance element is installed in the groove 11, the traction member 50 is in a retracted state and at least part of it is located below the resistance-capacitance element; the resistance-capacitance element replacement tool further comprises an elastic structure arranged in the groove 11 for applying an elastic force to the resistance-capacitance element towards the side away from the groove 11. In this way, when the traction member 50 is in a retracted state and located below the resistance-capacitance element, an elastic force is applied to the resistance-capacitance element by the elastic structure towards the opening direction of the groove, achieving precise fixation of the resistance-capacitance element. The above fixation method ensures that the resistance-capacitance element will not be displaced or fall off during the debugging process due to slight vibration or improper operation, thereby maintaining the stability of the signal path and the signal quality. At the same time, when the resistance-capacitance element needs to be replaced, the resistance-capacitance element can be easily released by controlling the extension and retraction of the traction member 50, achieving quick replacement of the resistance-capacitance element and significantly improving the debugging efficiency.

[0048] Specifically, the cooperation of the traction member 50 and the elastic structure ensures the optimal electrical contact between the resistance-capacitance element and the transmission main body 41. The elastic structure not only provides stable clamping of the resistance-capacitance element, but also adjusts the fit of the contact surface between the resistance-capacitance element and the transmission main body 41 through its elastic force, reducing the contact resistance and signal reflection, thereby optimizing the signal transmission performance. In addition, the retracted state of the traction member 50 can reduce the gap below the resistance-capacitance element, avoiding signal transmission interruption or attenuation caused by poor contact, and improving the reliability of electrical connection.

[0049] Optionally, the seat body 10 is made of insulating material; and / or, the first conductive part 42 is a first copper sheet; and / or, the second conductive part 43 is a second copper sheet, and the area of the second copper sheet is greater than or equal to the cross-sectional area of the electrode of the resistor-capacitor component. In this way, the seat body 10 is made of insulating material, effectively avoiding accidental electrical contact with other electronic components or metal structures during operation, reducing the risk of short circuit, electric shock or other electrical accidents, and providing higher level of safety protection for the debuggers. At the same time, the insulating seat body can isolate the electromagnetic interference in the environment, protect the purity of the signal, maintain the integrity of the signal transmission path, and is conducive to accurate measurement and analysis of signal characteristics.

[0050] In the embodiment, the first conductive part 42 is a first copper sheet, and the second conductive part 43 is a second copper sheet, and the area of the second copper sheet is greater than or equal to the cross-sectional area of the electrode of the resistor-capacitor component. In this way, the first copper sheet (the first conductive part 42) and the second copper sheet (the second conductive part 43) serve as conductive contact surfaces, and make use of the excellent electrical conductivity and corrosion resistance of copper to ensure low impedance and high efficiency electrical connection between the resistor-capacitor component and the PCB solder joint. In particular, the area of the second copper sheet is designed to be greater than or equal to the cross-sectional area of the electrode of the resistor-capacitor component, which not only maximizes the electrical contact area, reduces the contact pressure drop and signal loss, but also helps to disperse the pressure of the resistor-capacitor component electrode on the second copper sheet, avoiding the problem of poor contact or material wear caused by excessive local pressure. In addition, the larger contact area is also conducive to the rapid dissipation of heat, preventing overheating caused by long-term current flow, and further improving the stability of the electrical connection and the durability of the tool.

[0051] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0052] Through the ingenious design of the traction assembly, the replacement of the resistance-capacitance component can be quickly completed without any tools. When the traction component is in the stretched state, it will block part of the opening of the groove, thereby creating a stable space for placing the new resistance-capacitance component. Once the resistance-capacitance component is in place, the traction component is moved to the contracted state by adjusting the structure, so as to load the resistance-capacitance component into the groove. The second conductive part is in close contact with the resistance-capacitance component, forming a good electrical connection. In this way, the above process greatly simplifies the replacement step of the resistance-capacitance component, thereby solving the problem of low replacement efficiency of the resistance-capacitance component in the related art, avoiding the cumbersome and time-consuming use of traditional welding tools, and enabling hardware engineers to more quickly and conveniently perform signal debugging, effectively improving work efficiency and debugging accuracy. At the same time, the above arrangement of the signal transmission device ensures the signal transmission quality between the resistance-capacitance component and the board card, the first conductive part is electrically connected with the board card, the second conductive part is arranged on the groove wall of the groove and is in contact with the resistance-capacitance component, and the transmission main body is connected with the two, forming a stable signal path. The above design effectively avoids signal reflection caused by right-angle wiring, significantly reduces signal distortion, and improves the integrity and accuracy of the signal.

It should be noted that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
