Description

Technical Field

[0001] This utility model relates to the field of electronic measurement and instrumentation technology, and in particular to a circuit debugging signal acquisition interface device. Background Technology

[0002] Signal acquisition during circuit debugging, simply put, is the process of converting the invisible "voltage changes" or "logic states" on the circuit board into electrical signals that we can observe and analyze. This process requires connecting debugging equipment (such as an oscilloscope) to the circuit board's lines. During the circuit board's operation, the electrical signals of each line can be acquired. To facilitate the connection process, a circuit debugging signal acquisition interface device is proposed.

[0003] In existing technologies, the most common acquisition interface is the pen-style handheld probe. While flexible in operation, its limited quantity makes it difficult to guarantee the accuracy of signal acquisition for complex circuits. Furthermore, although most probe stations can assist in probe fixation, the probe position needs to be adjusted during circuit board mounting and unloading after debugging to ensure proper board handling. Therefore, probe adjustment is required again before subsequent debugging work, which severely impacts debugging efficiency when the workload is large. Utility Model Content

[0032] 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.

[0033] Traditional circuit debugging signal acquisition interface devices mostly use pen-style handheld probes, which are limited in number and make it difficult to guarantee the accuracy of signal acquisition for complex circuits. In addition, existing probe stations require repeated adjustments to the probe positions during circuit board fixing and cutting, which is not only time-consuming but also seriously affects the efficiency of debugging work.

[0034] In this regard, combined with Figure 1 and Figure 4 This embodiment proposes a circuit debugging signal acquisition interface device, including:

[0035] Base 10;

[0036] Two clamping members 20 are movably connected to the base 10; the two clamping members 20 are relatively close or far apart in the horizontal direction to clamp the circuit board to be debugged;

[0037] At least one acquisition component 60 is mounted on one side of the base 10 and is configured to acquire signals from the circuit board. The acquisition component 60 includes a rotating base 601 mounted on the base 10, a connection terminal 602 fixed to the rotating base 601, at least two movable rods, and a probe 608 rotatably connected to the movable rods having a free end. One of the movable rods is rotatably connected to the rotating base 601. Adjacent movable rods can rotate relative to each other. The tip of the probe 608 can abut against the circuit of the circuit board to be tested.

[0038] For ease of understanding, the following explains some key terms in this embodiment:

[0039] The base 10 serves as the support structure for the entire device, supporting other components and providing a stable working platform.

[0040] Clamping member 20 is used to fix the circuit board to be debugged. Its design allows the circuit board to be firmly clamped to ensure that the position of the circuit board remains unchanged during debugging.

[0041] The acquisition component 60 is a core component used to acquire electrical signals on the circuit board. It contacts the circuit board lines through the probe 608 and transmits the electrical signals to external debugging equipment.

[0042] The rotating base 601 is part of the acquisition component 60 and is mounted on the base 10. It enables the acquisition component 60 to rotate, thereby adjusting the overall orientation of the probe 608.

[0043] The connecting terminal 602, fixed to the rotating base 601, is typically used to provide electrical connections.

[0044] The movable arm is a structure that connects the rotating base 601 and the probe 608. It consists of at least two movable rods, which can rotate relative to each other, enabling the probe 608 to perform precise positioning at multiple angles and in multiple directions.

[0045] The probe 608 is a component that comes into direct contact with the circuit board lines. Its tip is designed to press against a specific line on the circuit board to collect the required electrical signal.

[0046] This embodiment provides a circuit debugging signal acquisition interface device. Specifically, the device includes a base 10, which serves as the basic support structure for the entire device. The bottom of the base 10 may be provided with an anti-slip pad to ensure the stability of the device on the workbench.

[0047] Two clamping members 20 are provided on the base 10. The clamping members 20 are movably connected to the base 10, so that they move closer or further apart in the horizontal direction. The circuit board to be debugged is clamped and fixed by the clamping members 20.

[0048] At least one acquisition component 60 is mounted on one side of the base 10, and its main function is to acquire signals from the circuit board.

[0049] The acquisition assembly 60 further includes a rotating base 601 mounted on the base 10, a connecting terminal 602 fixed to the rotating base 601, a movable arm, and a probe 608 rotatably connected to the free end of the movable arm. The rotating base 601 can be a disc-shaped structure connected to the base 10 via a central shaft, allowing it to rotate in a horizontal plane. The connecting terminal 602 can be directly soldered to the surface of the rotating base 601.

[0050] One section of the movable arm is rotatably connected to the rotating base 601. For example, one end of the movable arm can be hinged to the rotating base 601, thereby allowing it to swing around the hinge point. Adjacent sections of the movable arm can also rotate relative to each other, for example, by means of a pin or a damping bearing, enabling each section of the movable arm to perform multi-joint movements. Thus, the probe 608 can be guided to the target position on the circuit board.

[0051] The tip of probe 608 is designed to contact the traces on the circuit board to be tested. Probe 608 can be a thin, elongated metal needle. The tip of probe 608 can be adjusted by the angle and length of a movable lever to contact the target test point on the circuit board.

[0052] The circuit debugging signal acquisition interface device of this embodiment provides a movable and adjustable clamp 20 to securely fix the circuit board, preventing accidental movement of the circuit board during debugging. Simultaneously, the acquisition assembly 60, equipped with multiple movable rods and a rotating base 601, enables the probe 608 to perform precise positioning at multiple angles and directions. This effectively solves the problems of inaccurate probe positioning and repeated probe position adjustments in the prior art, improving the accuracy of signal acquisition for complex circuits and increasing the efficiency of circuit debugging.

[0053] Combination Figure 1 and Figure 2 In this embodiment, the base 10 is provided with a receiving groove 101; a sliding groove 102 is provided in the receiving groove 101 along the horizontal direction; a movable component is provided in the sliding groove 102; the movable part of the movable component is connected to the clamping member 20.

[0054] Specifically, the base 10 has a receiving groove 101, which is a recess or cavity structure formed inside or on the surface of the base 10. Its main function is to provide internal space for the subsequent moving mechanism, making the entire device compact and effectively protecting the internal components. The shape and size of the receiving groove 101 can be flexibly designed according to the needs of the components it accommodates.

[0055] Within the receiving groove 101, a sliding groove 102 is further formed horizontally. The horizontal orientation of the sliding groove 102 matches the horizontal movement direction of the clamping member 20. This sliding groove 102 provides a clear linear motion trajectory for the moving component, ensuring the stability and directionality of the clamping member 20 during movement and effectively avoiding unnecessary shaking or skewing. The sliding groove 102 can adopt a rectangular groove structure to accommodate the moving component.

[0056] A movable component is provided within the sliding groove 102. This movable component is the core mechanism for realizing the movement of the clamping member 20, and its design is intended to convert the internal driving force into the horizontal movement of the clamping member 20.

[0057] The movable part of the movable component is connected to the clamping member 20. The movable part refers to the part of the movable component that is directly mechanically connected to the clamping member 20 and transmits motion. This connection ensures that the movement of the movable component within the sliding groove 102 can be accurately and effectively transmitted to the clamping member 20, thereby driving the clamping member 20 to move relatively closer or further away to complete the clamping of the circuit board.

[0058] Through the above technical solution, the base 10 provides motion guidance and space for the movable component through the accommodating groove 101 and sliding groove 102, so that the movement path of the clamping member 20 is strictly limited to the horizontal direction. This significantly improves the stability and positioning accuracy of the clamping member 20 when clamping and releasing the circuit board, effectively solving the problems of unstable clamping and inaccurate positioning that may be caused by traditional simple movable connections. At the same time, through the connection between the movable component and the clamping member 20, effective driving and control of the clamping member 20 can be realized, making it more convenient and efficient to adjust the clamping width to adapt to circuit boards of different sizes, thereby improving the practicality and reliability of the entire circuit debugging signal acquisition interface device and ensuring the stability of the circuit board during the debugging process.

[0059] It should be noted that the number of acquisition components 60 can be designed according to the circuit board's line acquisition requirements, such as... Figure 1 As shown, in this embodiment, eight acquisition components 60 are provided on both sides of the base 10.

[0060] This embodiment further proposes that the movable component includes an elastic element 30 and a movable block 70 installed in the sliding groove 102.

[0061] The elastic element 30 is a component that can deform under external force and return to its original shape after the external force is removed. Its main function is to provide continuous elastic force to achieve automatic driving of the clamping member 20 or to apply a preset clamping force. The elastic element 30 can take various forms, such as a coil spring, and its selection depends on factors such as required elastic characteristics, space constraints, and cost. The movable block 70 is a component installed in the sliding groove 102 and capable of sliding along its length. Its main function is to act as a force transmission medium between the elastic element 30 and the clamping member 20, while also guiding the movement direction of the clamping member 20. The movable block 70 is usually designed with a smooth surface to ensure smooth movement within the sliding groove 102.

[0062] Specifically, the elastic element 30 is arranged along the length of the sliding groove 102 to ensure that the elastic force it generates can effectively act on the movable block 70 and ultimately be transmitted to the clamping member 20, causing it to move in the desired horizontal direction. One end of the elastic element 30 abuts against the inner wall of the sliding groove 102, and the other end abuts against the movable block 70. This arrangement allows the elastic element 30 to directly apply force to the movable block 70 when it is compressed or stretched, thereby driving the movable block 70 to move within the sliding groove 102. At the same time, the movable block 70 and the clamping member 20 are fixedly connected, ensuring that any movement of the movable block 70 can directly and stably drive the clamping member 20 to make a corresponding displacement, thereby realizing the control of the clamping member 20 and the effective transmission of force.

[0063] This embodiment further proposes that the aforementioned elastic element 30 is a spring. A spring is a common elastic element that stores and releases energy through the elastic deformation of a material, thereby providing a restoring force. In the circuit debugging signal acquisition interface device, specifically setting the elastic element 30 as a spring ensures a continuous and controllable elastic force when clamping the circuit board. When compressed, the spring provides a reaction force to push the movable block 70, thereby driving the clamping member 20.

[0064] This embodiment further proposes that the acquisition component 60 also includes a connecting base 603 fixed to the rotating seat 601; the connecting base 603 and one of the movable rods are rotatably connected.

[0065] Specifically, the connecting base 603 is a specially designed structural component that serves as an intermediate connector between the rotating seat 601 and the movable rod. The connecting base 603 is fixed to the rotating seat 601, meaning a robust, non-rotatable connection is formed between them. This connection can be achieved through screws, welding, riveting, or integral molding, ensuring that the connecting base 603 rotates synchronously with the rotating seat 601. Simultaneously, one section of the movable rod is rotatably connected to the connecting base 603, allowing for angular adjustment of the movable rod relative to the connecting base 603. This rotatable connection can be implemented using various methods such as pins, hinges, ball joints, or shafts with damping mechanisms to provide smooth and position-maintaining rotation.

[0066] This embodiment further proposes that the acquisition component 60 also includes a mounting base 606 rotatably connected to a movable rod having a free end, and a rotating rod 607 rotatably connected to the mounting base 606, with the probe 608 fixed inside the rotating rod 607.

[0067] Specifically, the mounting base 606 is a structural component used to connect and support other parts. Its function is to act as an intermediate connector between the free end of the movable rod and the rotating rod 607, providing an additional degree of rotational freedom and a mounting platform for the rotating rod 607. The mounting base 606 can be designed with a shaft hole or bearing seat to achieve a rotatable connection with the free end of the movable rod. This design allows the mounting base 606 to rotate about the free end of the movable rod, thereby adjusting its posture.

[0068] The rotating rod 607 is a rotatable rod-like structure that supports the probe 608 and allows the probe 608 to rotate relative to the mounting base 606, thereby enabling fine-tuning of the probe 608's angle. The rotating rod 607 can be designed as a slender cylindrical or polygonal rod, with one end rotatably connected to the mounting base 606. This rotatable connection can be achieved through bearings, pins, or ball joints to ensure smooth rotation and stable positioning. For example, one end of the rotating rod 607 can be inserted into a hole in the mounting base 606 and secured with fasteners or a damping structure, allowing it to be adjustable within a certain angle range and maintain its position.

[0069] The probe 608 is fixed within the rotating rod 607 to ensure a stable mechanical and electrical connection between the probe 608 and the rotating rod 607, allowing the tip of the probe 608 to be adjusted in angle and direction by rotating the rotating rod 607. The probe 608 can be fixed inside the rotating rod 607 by press-fit, threaded connection, welding, or gluing. For example, a hole matching the size of the probe 608 can be pre-drilled inside the rotating rod 607, into which the probe 608 is inserted and fixed, ensuring its tip is exposed and usable for contacting the circuit board.

[0070] This embodiment further proposes the above-mentioned circuit debugging signal acquisition interface device, wherein the movable rod has two sections, namely the first movable rod 604 and the second movable rod 605; one end of the first movable rod 604 is rotatably connected to the connecting base 603, and the other end is rotatably connected to the second movable rod 605; the free end of the second movable rod 605 is rotatably connected to the mounting base 606.

[0071] Specifically, the movable rod is clearly divided into two sections: the first movable rod 604 and the second movable rod 605. Compared to a single-section movable rod or an undefined segmented structure, this design provides more degrees of freedom, significantly increasing the motion trajectory and reach of the probe 608. This segmented design is the foundation for achieving complex spatial positioning. While maintaining a relatively compact structure, it provides sufficient flexibility, avoiding the limitations on movement in certain directions inherent in single-section rods, and also avoiding the structural complexity and control difficulties caused by too many sections. The first movable rod 604, as the first segment of the entire multi-section movable rod structure, is rotatably connected at one end to the connecting base 603. The connecting base 603 is fixed to the rotating seat 601; therefore, the first movable rod 604 can rotate or swing relative to the rotating seat 601 within a certain range around this connection point. This connection method is the starting joint of the entire probe 608 positioning system, providing the probe 608 with basic lateral or longitudinal movement capabilities, which is key to achieving large-range coarse adjustment. The other end of the first movable rod 604 is rotatably connected to the second movable rod 605, forming the intermediate joint of the movable rod. This joint allows the second movable rod 605 to rotate relative to the first movable rod 604. Through this intermediate joint, the trajectory of the probe 608 can be further bent and extended, greatly enhancing the probe 608's accessibility and obstacle avoidance capabilities in three-dimensional space. For example, when it is necessary to navigate around other components on a circuit board, this joint can provide the necessary bending angle. The free end of the second movable rod 605 is rotatably connected to the mounting base 606. The mounting base 606 carries the rotating rod 607 and the probe 608. This connection is the end joint of the probe 608 positioning system, allowing the mounting base 606 (and the probe 608) to be angularly adjusted relative to the second movable rod 605. This end rotatable connection is crucial for the precise positioning of the probe 608, ensuring that the tip of the probe 608 contacts the target trace on the circuit board at an optimal angle, guaranteeing stable electrical contact while avoiding damage to the trace.

[0072] This embodiment further proposes the use of a damping bearing at the rotating connection. A damping bearing is a specially designed bearing whose core function is to provide controllable rotational resistance to suppress unwanted free rotation and ensure that the connecting components can stably maintain their position after adjustment.

[0073] Specifically, damping bearings are configured at various rotational connection points of the acquisition assembly 60, such as between the rotating seat 601 and the connecting base 603, between the connecting base 603 and the first movable rod 604, between the first movable rod 604 and the second movable rod 605, between the second movable rod 605 and the mounting base 606, and between the mounting base 606 and the rotating rod 607.

[0074] By incorporating damping bearings at various rotating connections of the acquisition component 60, the positioning process of the probe 608 becomes more stable. The controllable resistance provided by the damping bearings effectively prevents accidental displacement of the moving rod and probe 608 due to gravity, vibration, or slight contact after adjustment, ensuring that the probe 608 firmly contacts the target circuit. When adjusting the position of the probe 608, the operator experiences a smooth and moderate damping sensation, facilitating fine-tuning. Once adjusted, the damping bearings lock the probe 608 in the preset position, greatly improving the accuracy and reliability of signal acquisition while reducing the frequency of repeated positioning and calibration, thus enhancing the overall efficiency of circuit debugging.

[0075] Meanwhile, the above technical solution enables the probe 608 to be angled, and after multiple probes 608 are placed against different lines, their positions can be adjusted to avoid interference between a large number of probes 608 and to avoid short circuits.

[0076] This embodiment further proposes that the circuit debugging signal acquisition interface device also includes an adjustment component; the adjustment component is configured to adjust the height of the acquisition component 60.

[0077] Specifically, an adjustment component is a mechanism used to change the relative position or attitude of other components, and its core function is to provide a controllable and stable height adjustment mechanism. The adjustment component is configured to adjust the height of the acquisition component 60, meaning there is a structural or functional connection between the adjustment component and the acquisition component 60, allowing the operation of the adjustment component to directly or indirectly affect the vertical position of the acquisition component 60. For example, the adjustment component can support the mounting platform of the acquisition component 60, adjusting the overall height of the acquisition component 60 by changing the vertical position of the platform. Alternatively, the adjustment component can be directly connected to a component of the acquisition component 60 (such as the rotating base 601), achieving the adjustment purpose by raising or lowering this component.

[0078] Combination Figure 1 and Figure 3 This embodiment further proposes a circuit debugging signal acquisition interface device, wherein the adjustment component includes a fixing rod 50 fixed to the base 10 and an adjustment plate 40 movably connected to the fixing rod 50; the acquisition component 60 is installed on the adjustment plate 40.

[0079] Specifically, the adjustment assembly is designed to provide a controllable vertical displacement mechanism to change the height of the acquisition assembly 60 relative to the base 10, thereby accommodating circuit boards of different thicknesses or test point heights. The fixing rod 50 is a vertically positioned support structure, firmly fixed at one end or bottom to the base 10. The fixing rod 50 can adopt various cross-sectional shapes, such as circular, square, or polygonal, to provide sufficient rigidity and stability. Its main function is to provide a stable guide track and support point for the adjustment plate 40. The adjustment plate 40 is a platform or support that can move up and down along the fixing rod 50. Its structure is typically designed with guiding features that mate with the fixing rod 50, such as through holes, grooves, or guide sleeves. The movable connection between the adjustment plate 40 and the fixing rod 50 refers to the mating relationship that allows relative vertical movement between the two. Specific implementations may include, but are not limited to: the adjustment plate 40 having holes that match the shape of the fixing rod 50, through which the fixing rod 50 passes, allowing the adjustment plate 40 to slide along the fixing rod 50. The acquisition component 60 is securely connected to the designated position of the adjustment plate 40 by mechanical means, such as screws, adhesive, or welding. This installation method ensures that the acquisition component 60 can move up and down synchronously with the vertical movement of the adjustment plate 40 as a whole, thereby achieving overall height adjustment.

[0080] The working principle of this embodiment is as follows:

[0081] First, the circuit board to be debugged is placed on the base 10 of the device. The base 10 has a receiving groove 101, and a sliding groove 102 is formed horizontally within the receiving groove 101. A movable component is provided within the sliding groove 102, which includes an elastic element 30, such as a spring, and a movable block 70. One end of the elastic element 30 abuts against the inner wall of the sliding groove 102, and the other end abuts against the movable block 70. The movable block 70 is fixedly connected to a clamping member 20.

[0082] Once the circuit board is inserted, the elastic force of the elastic element 30 causes the movable block 70 to push the clamping member 20, thereby firmly clamping the circuit board between the two clamping members 20. This design makes the circuit board fixing process quick and stable, avoiding the inconvenience and instability of traditional manual clamping.

[0083] Next, the probes 608 of the acquisition component 60 need to be positioned at multiple test points on the circuit board. The device has multiple acquisition components 60 mounted on one side of the base 10. Each acquisition component 60 is mounted on an adjustment plate 40, which is movably connected to a fixing rod 50 fixed to the base 10, forming an adjustment assembly. The adjustment plate 40 can be adjusted up or down according to the height of the circuit board or the requirements of the test points, thereby adjusting the overall height of the acquisition component 60.

[0084] After adjusting the height, the probe 608 is positioned. Each acquisition assembly 60 includes a rotating base 601 mounted on the adjustment plate 40. A connecting terminal 602 is fixed on the rotating base 601. A connecting base 603 is also fixed to the rotating base 601. The connecting base 603 is rotatably connected to one end of a first movable rod 604. The other end of the first movable rod 604 is rotatably connected to a second movable rod 605. The free end of the second movable rod 605 is rotatably connected to a mounting base 606. The probe 608 is fixed inside a rotating rod 607 within the mounting base 606, and the rotating rod 607 is rotatably connected to the mounting base 606. Damping bearings are provided at all these rotating connections.

[0085] By manipulating the first movable lever 604, the second movable lever 605, and the rotating lever 607, the tip of the probe 608 is moved to a predetermined test point on the circuit board. Because a damping bearing is installed at the rotating connection, the movement of the probe 608 is smooth and provides appropriate resistance. Once positioned, the probe 608 remains stably in that position, without shifting due to slight vibrations or its own weight, ensuring the accuracy of signal acquisition. This contrasts sharply with traditional handheld probes, which require the operator to maintain constant stability, or probes without damping that are prone to wobbling, significantly improving positioning accuracy and stability.

[0086] Once all probes 608 are in contact with the circuitry on the circuit board, the alligator clips of the oscilloscope and other equipment are clamped onto the connection terminal 602. Since the connection terminal 602 and probes 608 correspond one-to-one and are electrically connected, the alligator clips can form an electrical connection with the circuitry on the circuit board after being clamped onto the connection terminal 602, and signal acquisition and debugging work can begin.

[0087] After debugging one circuit board, it needs to be replaced with the next. Simply loosen the clamp 20, remove the debugged circuit board, insert the new circuit board, and re-clamp it. Since the acquisition component 60 and its probe 608 are mounted on the base 10, and the probe 608 is stably held in its original position by a damping bearing, the position of the probe 608 does not need to be readjusted during circuit board replacement. This greatly simplifies the batch debugging workflow, avoids the tedious operation of repeatedly adjusting the probe position after replacing a circuit board, as required by traditional probe stations, and thus significantly improves debugging efficiency.

[0088] As can be seen from the above example, the base 10, clamping component 20, and acquisition component 60 of the device work together to achieve rapid and stable clamping of the circuit board, stable positioning of the probe, and convenient replacement of the circuit board. In particular, the combination of the multi-section movable rod and the damping bearing solves the problems of insufficient accuracy of traditional handheld probes and low efficiency caused by repeated probe position adjustments in existing probe stations, making signal acquisition of complex circuits both accurate and efficient.

[0089] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. 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.
