Description

Technical Field

[0001] The utility model relates to the technical field of circuit detection, in particular to a detection tool for detecting an integrated circuit board. Background Technique

[0002] An integrated circuit board uses semiconductor manufacturing technology to fabricate many transistors, resistors, capacitors and other components on a small single-crystalline silicon wafer, and combines the components into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring. The damage of an integrated circuit board is generally the damage of a certain component, which may be a certain chip, a certain capacitor, or even a small resistor. The repair process is to find out the damaged component and replace it. This seems simple, but actually requires profound knowledge, rich experience and necessary detection equipment.

[0003] The existing detection tools for detecting integrated circuit boards generally have only one detection angle. Either straight-pin detection is used. Operators often need to stop the current work, remove the original straight-pin detection head, and then replace it with a new detection head with vertical probes. This frequent replacement operation not only increases the complexity of the detection process, but also greatly reduces the overall detection efficiency. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a detection tool for detecting an integrated circuit board to solve the technical problem of time-consuming replacement of the detection head.

[0005] To achieve the above object, the utility model provides the following technical scheme: A detection tool for detecting an integrated circuit board, including a multimeter. A jack is fixedly connected to the top of the multimeter. A wire is inserted into the jack. An adjusting mechanism is sleeved on the outer side of one end of the wire. The adjusting mechanism includes a housing. A first connecting rod is rotatably connected to the housing through a torsion rotating shaft. One end of the first connecting rod is rotatably connected to a second connecting rod. One end of the second connecting rod is rotatably connected to a third connecting rod. A clamping block is fixedly connected to one end of the third connecting rod. The clamping block is rotatably connected to the housing;

[0006] A clamp is arranged below the second connecting rod. A first clamping groove and a second clamping groove are formed inside the clamp. The material of the clamp is an elastic material.

[0007] By adopting the above technical scheme, through the design of the adjusting mechanism, users can easily adjust the angle of the detection needle, so that the detection tool can adapt to different detection requirements. Whether in a narrow space or in a situation where a specific angle is required to contact the circuit board, effective detection can be carried out.

[0008] Further, the third connecting rod is obliquely arranged.

[0009] By adopting the above technical solution, by setting the third connecting rod obliquely, the flexibility and adjustable range of the adjusting mechanism can be increased, making the relative movement between the first connecting rod, the second connecting rod and the third connecting rod smoother, and facilitating the user to adjust the detection needle to the required angle.

[0010] Further, a rotating groove is formed on one side inside the clamping block, and a wire hole is formed inside the clamping block.

[0011] By adopting the above technical solution, by forming a rotating groove on one side inside the clamping block, space is provided for the rotation of the wire, ensuring that the clamping block can rotate smoothly, and then driving the wire and the detection needle to adjust the angle.

[0012] Further, the wire hole is clamped with the wire through a snap ring, and one end of the wire is fixedly connected with a detection needle.

[0013] By adopting the above technical solution, by clamping the wire with the snap ring in the wire hole, the wire can be ensured to be fixed in the adjusting mechanism, effectively preventing the wire from sliding or falling off during the adjustment process, thereby ensuring the stable connection between the adjusting mechanism and the wire.

[0014] Further, a movable clamp is arranged below the second connecting rod, and a third clamping groove is formed inside the movable clamp.

[0015] By adopting the above technical solution, by arranging a movable clamp below the second connecting rod and forming a third clamping groove inside the movable clamp, the user can adjust the position of the movable clamp as needed, thereby changing the angle and position of the detection needle to adapt to the detection requirements of integrated circuit boards with different shapes and layouts.

[0016] Further, an adjusting stud is threadedly connected to one side of the movable clamp, and a guiding rod is slidably connected to the other side of the movable clamp.

[0017] By adopting the above technical solution, through the adjusting stud threadedly connected to one side of the movable clamp, the user can conveniently adjust the up and down position of the movable clamp, thereby precisely controlling the angle of the detection needle, making the adjustment process more stable and controllable, and meeting the user's fine adjustment requirements for different detection angles.

[0018] Further, the bottom end of the adjusting stud is rotatably connected to the housing, and the bottom end of the guiding rod is fixedly connected to the housing.

[0019] By adopting the above technical solution, the bottom end of the adjusting stud is rotatably connected to the housing, ensuring that the adjusting stud can rotate freely when needed while maintaining the structural stability. The user can precisely adjust the position of the movable clamp by rotating the adjusting stud, and then change the angle of the detection needle to meet different detection requirements.

[0020] In summary, the present utility model mainly has the following beneficial effects:

[0021] 1. By setting an adjustment mechanism in the present utility model, users can easily adjust the angle of the detection needle to meet different detection requirements, enabling this detection tool to adapt to various complex circuit board layouts, improving the convenience and efficiency of detection. The design of the four-bar linkage mechanism makes the angle adjustment of the detection needle more stable and reliable. By pushing the first link, users can quickly adjust the angle of the detection needle, and the design of the clamping block ensures that the detection needle can remain at the required angle after adjustment without shaking or deviation, improving the flexibility and accuracy of detection, and also making the detection process more efficient and convenient;

[0022] 2. By setting a movable clamp, a guide rod and an adjusting stud in the present utility model, users can achieve fine adjustment of the angle of the detection needle. Rotating the adjusting stud can drive the movable clamp to move up and down, thereby changing the angle of the detection needle. This provides users with more flexibility and choice space, increases the adjustment range of the detection needle, enables the detection tool to adapt to more different angle detection requirements, and enhances the adaptability and practicality of the detection tool.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0029] The embodiments of the present utility model will be described below according to its overall structure.

[0030] Embodiment 1:

[0031] A detection tool for integrated circuit board detection, as Figures 1-4 shown, includes a multimeter 1. A jack 2 is fixedly connected to the top of the multimeter 1. A wire 3 is inserted into the interior of the jack 2. An adjustment mechanism 4 is sleeved on the outer side of one end of the wire 3. The adjustment mechanism 4 includes a housing 401. A first connecting rod 402 is rotatably connected to the housing 401 through a torsion rotating shaft. One end of the first connecting rod 402 is rotatably connected to a second connecting rod 403. One end of the second connecting rod 403 is rotatably connected to a third connecting rod 404. A clamping block 405 is fixedly connected to one end of the third connecting rod 404. The clamping block 405 is rotatably connected to the housing 401;

[0032] Below the second connecting rod 403, there is a clamp 406. A first clamping groove 407 and a second clamping groove 408 are formed inside the clamp 406. The material of the clamp 406 is an elastic material. Through the design of the adjustment mechanism 4, users can easily adjust the angle of the detection needle 5, enabling the detection tool to adapt to different detection requirements. Whether in a narrow space or when a specific angle is required to contact the circuit board, effective detection can be carried out. At the same time, the setting of the clamp 406 provides stable fixation for the detection needle 5. The first clamping groove 407 and the second clamping groove 408 inside it can respectively fix the detection needle 5 at different angular positions, ensuring the stability and accuracy of the detection process.

[0033] Refer to Figure 1 、 Figure 2 and Figure 3 , the third connecting rod 404 is obliquely arranged. By setting the third connecting rod 404 obliquely, the flexibility and adjustable range of the adjustment mechanism 4 can be increased, making the relative movement between the first connecting rod 402, the second connecting rod 403, and the third connecting rod 404 smoother, facilitating users to adjust the detection needle 5 to the required angle, improving the user experience, and also extending the service life of the detection tool.

[0034] Refer to Figure 1 、 Figure 2 and Figure 3, a rotating groove 409 is provided on one inner side of the clamping block 405, and a wire hole 410 is provided inside the clamping block 405. By providing the rotating groove 409 on one inner side of the clamping block 405, space is provided for the rotation of the wire 3, ensuring that the clamping block 405 can rotate smoothly, thereby driving the wire 3 and the detection needle 5 to adjust the angle. At the same time, the wire hole 410 provided inside the clamping block 405 provides a stable channel for the wire 3, ensuring the stability and safety of the wire 3 during the movement of the adjusting mechanism 4, preventing the wire 3 from being damaged during the adjustment process, and also ensuring that the electrical connection between the detection needle 5 and the multimeter 1 always remains good, thereby improving the accuracy and reliability of the detection.

[0035] Refer to Figure 1 , Figure 2 and Figure 3 , the wire hole 410 is engaged with the wire 3 through a snap ring 411. One end of the wire 3 is fixedly connected with a detection needle 5. By engaging the snap ring 411 in the wire hole 410 with the wire 3, it can be ensured that the wire 3 remains fixed in the adjusting mechanism 4, effectively preventing the wire 3 from sliding or falling off during the adjustment process, thereby ensuring the stable connection between the adjusting mechanism 4 and the wire 3. At the same time, the detection needle 5 fixedly connected to one end of the wire 3 can ensure the stable transmission of electrical signals, reducing signal loss and interference, thereby improving the accuracy and reliability of the detection.

[0036] The implementation principle of the present utility model is as follows: First, when the multimeter 1 needs to be used, the wire 3 is inserted into the inside of the jack 2, and then the outer shell 401 is held to detect the circuit board to be measured. When the angle of the detection needle 5 needs to be changed, the first connecting rod 402 is pushed. The first connecting rod 402 drives the second connecting rod 403 to rotate. Then, the second connecting rod 403 drives the inclined third connecting rod 404 to move. The inclined third connecting rod 404 can achieve a larger adjustment range. At the same time, through the four-bar mechanism formed by the connecting rods, the clamping block 405 is driven to rotate. The rotation of the clamping block 405 drives the wire 3 and the detection needle 5 inside the wire hole 410 to rotate. When the second connecting rod 403 is inserted into the first card slot 407, the detection needle 5 is in an inclined state. When the second connecting rod 403 is inserted into the inside of the second card slot 408, the detection needle 5 is in a vertical state, realizing the conversion of different states of the detection needle 5;

[0037] When it is necessary to return to the horizontal position, the second connecting rod 403 is pulled outwards. At this time, the torsion rotating shaft drives the first connecting rod 402 to reset, and the clamping block 405 is pulled back through the four-bar mechanism to complete the reset of the detection needle 5.

[0038] Embodiment 2:

[0039] Refer to Figure 4An active card 6 is arranged below the second connecting rod 403, and a third card slot 7 is opened inside the active card 6. By arranging the active card 6 below the second connecting rod 403 and opening the third card slot 7 inside the active card 6, the user is allowed to adjust the position of the active card 6 as needed, thereby changing the angle and position of the detection needle 5 to meet the detection requirements of integrated circuit boards of different shapes and layouts. At the same time, when the user inserts the second connecting rod 403 into the third card slot 7, the detection needle 5 will be fixed at a specific angle and position. The adjustable and fixable design makes the detection tool more practical and convenient, and improves the detection efficiency and quality.

[0040] See also Figure 4 One side of the active card 6 is threadedly connected with an adjusting stud 8, and the other side of the active card 6 is slidably connected with a guide rod 9. Through the adjusting stud 8 threadedly connected on one side of the active card 6, the user can easily adjust the up and down position of the active card 6, thereby accurately controlling the angle of the detection needle 5, making the adjustment process more stable and controllable, and meeting the user's fine adjustment needs for different detection angles. At the same time, the guide rod 9 slidably connected on the other side of the active card 6 ensures the stability and straightness of the active card 6 during the up and down movement. The guide rod 9 not only provides a stable sliding track for the active card 6, but also effectively prevents the active card 6 from deflecting or rotating during the adjustment process, thereby ensuring the accuracy and reliability of the angle adjustment of the detection needle 5.

[0041] See also Figure 4 The bottom end of the adjusting stud 8 is rotatably connected to the shell 401, and the bottom end of the guide rod 9 is fixedly connected to the shell 401. The bottom end of the adjusting stud 8 is rotatably connected to the shell 401, ensuring that the adjusting stud 8 can rotate freely when needed while maintaining the stability of the structure. The user can accurately adjust the position of the active card 6 by rotating the adjusting stud 8, thereby changing the angle of the detection needle 5 to meet different detection requirements. At the same time, the bottom end of the guide rod 9 is fixedly connected to the shell 401, providing stable support and guidance for the sliding of the active card 6, ensuring the stability of the guide rod 9, so that the active card 6 can always maintain linear motion during the up and down sliding process without offset or shaking.

[0042] The implementation principle of the utility model is: first, when more angles are needed, rotate the adjusting stud 8 to drive the movable card 6 to move up and down and adjust it to a suitable position, so that when the second connecting rod 403 is inserted into the inside of the third card slot 7, it can drive the detection needle 5 to be at a suitable angle, thereby increasing the adjustment range of the detection needle 5.
