Abstract

Technical Field
[0001] This utility model belongs to the field of internal resistance detection technology, specifically a fixing structure for internal resistance strips that can be quickly detected. Background Technology
[0002] Traditional methods of measuring resistance often involve directly touching the internal resistance bar with a tester, which requires manual alignment of the test point. This is very time-consuming. Furthermore, due to manual testing, the probe pressure is uneven, which can easily cause vibration and large fluctuations in contact resistance. Some testers cannot monitor for long periods of time, cannot fix the probe, and cannot monitor online. Utility Model Content
[0003] To address the problems mentioned in the background section, this invention provides a fast-detecting internal resistance strip fixing structure to solve the efficiency, accuracy, and cost issues associated with manual internal resistance detection.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fast-detectable internal resistance strip fixing structure, characterized in that it comprises a base, a buckle, a conductive clip, and a fixing plate. The base is rectangular and hollow inside. A fixing plate is provided at the center of the top of the base. The fixing plate is telescopic. The buckle is installed on the side of the base parallel to the telescopic direction of the fixing plate. The conductive clip is located inside the base. A locking hole is provided on the side of the base where the buckle is installed. A support rod is provided on the buckle. The support rod and the locking hole are interlocked, and one end of the support rod is connected to the buckle, and the other end is connected to the bottom of the conductive clip.
[0005] Optionally, the fixing plate consists of a base plate, a telescopic plate, round rods, and first springs. The base plate is located at the center of the top of the base. The telescopic plate is symmetrically connected to both sides of the base plate by multiple round rods. The base plate is hollow inside. The multiple first springs are installed inside the base plate. Each first spring is connected to the symmetrical round rods on both sides. A pull rod is provided on the telescopic plate. A contact port is provided at the center of the base plate.
[0006] Optionally, the base surface is provided with mating holes, the positions of which coincide with the connection points between the conductive clip and the two sides of the base.
[0007] Optionally, the conductive clip is configured as an inverted U-shape, with the arc of the conductive clip engaging with the contact port, the arc of the conductive clip being higher than the height of the base plate, and a mating interface being provided at the connection between the conductive clip and the base. A second spring is provided on the conductive clip, with the other end of the second spring connected to the base. Optionally, the latch consists of a triangular rod and a rotating rod, the support rod is connected to the top of the rotating rod, and the triangular rod and the rotating rod are connected by a rotating shaft. When the device is fixed, the triangular rod is snapped onto the battery frame assembly.
[0008] Optionally, the base is provided with pressing grooves on both sides of the mating hole.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the user can align one side of the device's fixing plate with the internal resistance strip on the battery pack to be measured. By pulling the lever, the first spring deforms, increasing the width of the telescopic plate. Then, the user presses the base with the pressing groove, causing the internal resistance strip to engage with the base plate and the telescopic plate. Next, the user engages the triangular rod with the battery frame assembly and pulls the rotating rod, causing the support rod to move upward. At this time, the conductive clamp also moves upward. However, due to the presence of the contact port, the arc surface of the conductive clamp makes more sufficient contact with the internal resistance strip. Finally, the measuring probe of the detector is inserted into the docking hole and the interface to start measuring the internal resistance. The process is completed as follows: detection probe (+) → conductive clamp → upper surface of internal resistance strip → battery terminal → battery interior → other terminal → lower surface of internal resistance strip → conductive clamp → detection probe (-). This device allows the positioning to be completed when the base is closed, the elastic clamping is constant pressure, the contact resistance fluctuation remains unchanged, and the base supports real-time detection after it is fixed, which greatly improves the efficiency, accuracy, and stability of resistance measurement. In this invention, the base can be fixed by a locking buckle, and the measuring probe on the detector can be inserted into the docking hole to perform the measurement. This device greatly reduces the cost of manual learning. Operators do not need to learn skills such as four-wire probe crimping. They only need to close the device with one click, and there is no operational threshold. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] like Figures 1 to 7 As shown, this utility model provides a fast-detectable internal resistance strip fixing structure, characterized in that it comprises a base 1, a latch 2, a conductive clip 3, and a fixing plate 4. The base 1 is rectangular and hollow inside. The fixing plate 4 is set at the center of the top of the base 1. The fixing plate 4 is telescopic. The latch 2 is installed on the side of the base 1 parallel to the telescopic direction of the fixing plate 4. The conductive clip 3 is set inside the base 1. The side of the base 1 on which the latch 2 is installed is provided with a locking hole 5. The latch 2 is provided with a support rod 6. The support rod 6 is engaged with the locking hole 5, and one end of the support rod 6 is connected to the latch 2, and the other end is connected to the bottom of the conductive clip 3.
[0013] Using the above scheme: In this utility model, the user can align one side of the device fixing plate 4 with the internal resistance strip on the battery pack to be measured. By pulling the pull rod 11, the first spring 10 deforms, causing the width of the telescopic plate 8 to increase. At this time, the user can press the base 1 through the pressing groove 20, so that the internal resistance strip is engaged with the base plate 7 and the telescopic plate 8. Then, the triangular rod 16 is engaged with the battery frame assembly 19, and the rotating rod 17 is pulled, causing the support rod 6 to move upward. At this time, the conductive clip 3 also moves upward. However, due to the presence of the contact port 12, the arc surface of the conductive clip 3 makes more sufficient contact with the internal resistance strip. Finally, the measuring probe of the detector is engaged in the docking hole 13 and the docking interface 14 to start measuring the internal resistance. The process is as follows: probe (+) → conductive clip → upper surface of internal resistance strip → battery terminal → battery interior → other terminal → lower surface of internal resistance strip → conductive clip → The detection probe (-) process allows the closed base 1 to complete the positioning, elastic clamping constant pressure, and constant contact resistance fluctuation. Furthermore, the base 1 supports real-time detection after it is fixed, which greatly improves the efficiency, accuracy and stability of resistance measurement.
[0014] The fixing plate 4 consists of a base plate 7, a telescopic plate 8, round rods 9, and a first spring 10. The base plate 7 is located at the top center of the base 1. The telescopic plate 8 is symmetrically connected to both sides of the base plate 7 by multiple round rods 9. The base plate 7 is hollow inside. The multiple first springs 10 are installed inside the base plate 7. Each first spring 10 is connected to the symmetrical round rods 9 on both sides. A pull rod is provided on the telescopic plate 8. A contact port 12 is provided at the center of the base plate 7.
[0015] The base 1 has a docking hole 13 on its surface, and the position of the docking hole 13 is consistent with the connection between the conductive clip 3 and the two sides of the base 1.
[0016] The conductive clip 3 is configured as an inverted U-shape, with the arc of the conductive clip 3 engaging with the contact port 12. The height of the arc of the conductive clip 3 is higher than the height of the base plate 7. A mating interface 14 is provided at the connection between the conductive clip 3 and the base 1. A second spring 15 is provided on the conductive clip 3, and the other end of the second spring 15 is connected to the base 1. Using the above solution: the second spring 15 deforms when the support rod 6 is pulled up. When the user wants to release the device from its fixed state, after pulling up the lock 2, the support rod 6 will automatically move downward due to the second spring 15, without the user needing to adjust it again.
[0017] The latch 2 consists of a triangular rod 16 and a rotating rod 17. The support rod 6 is connected to the top of the rotating rod 17. The triangular rod 16 and the rotating rod 17 are connected by a rotating shaft 18. When the device is fixed, the triangular rod 16 is snapped onto the battery frame assembly 19.
[0018] Using the above solution: In this utility model, the base 1 can be fixed by fixing the locking buckle 2, and then the measuring needle on the detector can be inserted into the docking hole 13 to perform the measurement. This device greatly reduces the cost of manual learning. Operators do not need to learn skills such as four-wire probe crimping. They only need to close it with one button, and there is no operational threshold.
[0019] The base 1 has pressing grooves 20 on both sides of the mating hole 13.
[0020] The working principle and usage process of this utility model are as follows: The user can align one side of the device fixing plate 4 with the internal resistance strip on the battery pack to be measured. By pulling the pull rod 11, the first spring 10 deforms, causing the width of the telescopic plate 8 to increase. At this time, the user can press the base 1 through the pressing groove 20, so that the internal resistance strip is engaged with the base plate 7 and the telescopic plate 8. Then, the triangular rod 16 is engaged with the battery frame assembly 19. Pulling the rotating rod 17 causes the support rod 6 to move upward. At this time, the conductive clip 3 also moves upward. However, due to the presence of the contact port 12, the arc surface of the conductive clip 3 makes more sufficient contact with the internal resistance strip. Finally, the measuring probe of the detector is engaged in the docking hole 13 and the docking interface 14 to start measuring the internal resistance. The process is as follows: Probe (+) → Conductive clip → Upper surface of internal resistance strip → Battery terminal → Battery interior → Another terminal → Lower surface of internal resistance strip → Conductive clip → The detection probe (-) process allows the closed base 1 to complete the positioning, elastic clamping constant pressure, and constant contact resistance fluctuation. Furthermore, the base 1 supports real-time detection after it is fixed, which greatly improves the efficiency, accuracy and stability of resistance measurement.
