It includes a platform panel on which a testing component is mounted. A pressure head and probe assembly are positioned on top of the testing component. This testing structure, by having the testing component and pressure head / probe assembly mounted on the platform panel, works together to automatically measure the parameters of the current sensor. It features simple operation, high testing efficiency, high accuracy, high automation, good safety, reliable results, a simple mechanism, low equipment cost, and convenience. This avoids the cumbersome process of using multiple sets of equipment, such as digital oscilloscopes, programmable power supplies, and benchtop digital multimeters, to test each current sensor in traditional methods, effectively saving time and significantly reducing labor costs.

[0003] Based on the above-mentioned documents: As a core detection component in fields such as power systems, industrial automation, and new energy, the performance of current sensors directly affects the stability and reliability of the system. However, traditional current sensor testing fixtures can only test one sensor at a time, and each test requires manual installation and disassembly of the current sensor, which is inefficient and cannot achieve batch testing, thus failing to meet the needs of large-scale production. Therefore, this utility model provides a batch testing fixture for current sensors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a batch testing fixture for current sensors, which solves the problems of low efficiency, inability to perform batch testing, and inability to meet the needs of large-scale production of traditional current sensor testing fixtures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a batch testing fixture for current sensors, comprising a fixture plate and a current sensor body. The top of the fixture plate is provided with a terminal docking assembly, and the interior of the fixture plate is provided with a positioning mechanism for clamping and positioning the current sensor body. The positioning mechanism includes:

[0006] The positioning assembly includes a support rod installed on the inner wall of a tooling plate, a positioning plate slidably connected to the surface of the support rod, a symmetrical inclined groove formed on the surface of the positioning plate, a positioning rod slidably connected to the inner surface of the inclined groove, and the top end of the positioning rod extending through to the top of the tooling plate.

[0007] The drive assembly, located on one side of the tooling plate, is used to drive the sliding of multiple sets of positioning plates;

[0008] The limiting component, located inside the tooling plate, is used to limit the positioning rod.

[0009] Preferably, the tooling plate has multiple sets of placement slots on its top, and the top of the inner cavity of each placement slot has a symmetrical sliding groove, the inner surface of which is slidably connected to the surface of the positioning rod.

[0010] Preferably, the drive assembly includes a drive motor mounted on one side of the tooling plate, one end of the output shaft of the drive motor is fixedly connected to a drive screw via a coupling, a drive block is threaded onto the surface of the drive screw, and the top of the drive block is fixedly connected to the bottom of the positioning plate.

[0011] Preferably, the limiting assembly includes a limiting plate installed on the inner wall of the tooling plate, and a symmetrical limiting block is slidably connected inside the limiting plate. The top of the limiting block is fixedly connected to the bottom end of the positioning rod.

[0012] Preferably, the terminal docking assembly includes a docking cylinder mounted on the top of the tooling plate. The output end of the docking cylinder is fixedly connected to a connecting plate. A detection terminal is fixedly connected to one side of the connecting plate, and a quick-connect connector is fixedly connected to the other side of the connecting plate. A connecting rod is fixedly connected to one end of the connecting plate, and the connecting rod is used to connect multiple sets of connecting plates.

A signal output terminal is provided on one side of the current sensor body, and the signal output terminal is adapted to the detection terminal.

[0014] Beneficial effects

[0015] This invention provides a batch testing fixture for current sensors. Compared with the prior art, it has the following advantages:

[0016] 1. This current sensor batch testing fixture, when activated by a drive motor, rotates a drive screw. The rotation of the drive screw causes the drive block and positioning plate to slide synchronously to one side, allowing the positioning plate to slide on the surface of the support rod. As the positioning plate slides, the positioning rods slide on the inner surface of the inclined slide groove. Limited by the inclined slide groove, the positioning rods on both sides slide synchronously to opposite sides. The limiting block at the bottom of the positioning rod slides within a limiting groove on the surface of the limiting plate. As the positioning rods slide, they slide into the mounting grooves on both sides of the mounting base at the bottom of the current sensor body. The positioning rods on both sides clamp and position the current sensor body. With a positioning mechanism, multiple sets of positioning rods can slide synchronously under the drive motor. The symmetrically designed positioning rods on both sides can quickly clamp and position multiple sets of current sensor bodies placed in the mounting groove, thus maintaining the stability of the current sensor body and facilitating subsequent batch testing operations.

[0017] 2. This current sensor batch testing fixture uses a docking cylinder to synchronously slide the connecting plate, detection terminals, and connecting rod. The sliding of the connecting rod causes multiple sets of connecting plates and detection terminals to slide synchronously, allowing the detection terminals to slide into the signal output terminals for connection. Then, it connects to external testing equipment via quick-connect connectors. Finally, a current-carrying wire or energized copper plate is passed through an opening on the surface of the current sensor body. After power is applied, multiple sets of current sensors are batch tested by the testing equipment. The fixture features a terminal docking assembly, which, driven by the docking cylinder, allows for rapid adjustment of the positions of the connecting plate, detection terminals, and connecting rod. The connecting rod enables synchronous adjustment of the positions of multiple sets of connecting plates and detection terminals, allowing multiple detection terminals to quickly and synchronously connect to the corresponding signal output terminals on the surface of the current sensor body, achieving rapid terminal docking. Finally, the quick-connect connectors facilitate convenient connection to external testing equipment, enabling batch testing of current sensors. Attached Figure Description

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.

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A batch testing fixture for current sensors includes a fixture plate 1 and a current sensor body 2. The top of the fixture plate 1 is provided with a terminal mating assembly 3, and the interior of the fixture plate 1 is provided with a positioning mechanism 4 for clamping and positioning the current sensor body 2.

[0028] The positioning assembly 41 includes a support rod 411 installed on the inner wall of the tooling plate 1. A positioning plate 412 is slidably connected to the surface of the support rod 411.

The top end of the positioning rod 414 extends through to the top of the tooling plate 1.

[0029] The drive assembly 42 is located on one side of the tooling plate 1 and is used to drive the sliding of multiple sets of positioning plates 412.

[0030] The limiting component 43 is disposed inside the tooling plate 1 and is used to limit the positioning rod 414.

[0031] The support rod 411 is used to slide and limit the positioning plate 412;

[0032] Multiple positioning plates 412 are fixed together by support plates.

[0033] In this embodiment, the top of the tooling plate 1 is provided with multiple sets of placement grooves 5, and the top of the inner cavity of the placement groove 5 is provided with symmetrical sliding grooves 6. The inner surface of the sliding groove 6 is slidably connected to the surface of the positioning rod 414.

[0034] In this embodiment, the drive assembly 42 includes a drive motor 421 mounted on one side of the tooling plate 1. One end of the output shaft of the drive motor 421 is fixedly connected to a drive screw 422 via a coupling. A drive block 423 is threadedly connected to the surface of the drive screw 422. The top of the drive block 423 is fixedly connected to the bottom of the positioning plate 412.

[0035] The drive motor 421 is a three-phase asynchronous motor and is connected to an external circuit via wires;

[0036] The lead screw 422 rotates inside the tooling plate 1.

[0037] In this embodiment, the limiting component 43 includes a limiting plate 431 installed on the inner wall of the tooling plate 1. A symmetrical limiting block 432 is slidably connected inside the limiting plate 431. The top of the limiting block 432 is fixedly connected to the bottom end of the positioning rod 414.

[0038] The top of the limiting plate 431 is provided with a limiting groove for the limiting block 432 to slide. The positioning rod 414 can be slidably limited by the limiting plate 431 and the limiting block 432.

[0039] With the positioning mechanism 4 in place, multiple positioning rods 414 can be driven to slide synchronously by the drive motor 421. The positioning rods 414 with symmetrical design on both sides can quickly clamp and position multiple current sensor bodies 2 placed in the placement slot 5, thereby maintaining the stability of the current sensor bodies 2 and facilitating subsequent batch testing operations.

[0040] In this embodiment, the terminal docking assembly 3 includes a docking cylinder 31 mounted on the top of the tooling plate 1. The output end of the docking cylinder 31 is fixedly connected to a connecting plate 32. A detection terminal 33 is fixedly connected to one side of the connecting plate 32, and a quick-connect connector 34 is fixedly connected to the other side of the connecting plate 32. A connecting rod 35 is fixedly connected to one end of the connecting plate 32. The connecting rod 35 is used to connect multiple sets of connecting plates 32.

[0041] The docking cylinder 31 is connected to an external air source via an air pipe;

[0042] Multiple sets of fixing blocks are installed on one side of the tooling plate 1. The connecting rod 35 slides inside the fixing block, and the fixing block can limit the sliding of the connecting rod 35.

[0043] In this embodiment, a mounting base 7 is installed at the bottom of the current sensor body 2. Mounting slots 8 that are adapted to the positioning rod 414 are opened on both sides of the mounting base 7. A signal output terminal 9 is provided on one side of the current sensor body 2. The signal output terminal 9 is adapted to the detection terminal 33.

[0044] By using the terminal docking assembly 3 and driven by the docking cylinder 31, the positions of the connecting plate 32, detection terminal 33, and connecting rod 35 can be quickly adjusted. The connecting rod 35 allows for the synchronous adjustment of the positions of multiple sets of connecting plates 32 and detection terminals 33, enabling multiple sets of detection terminals 33 to quickly and synchronously connect to the signal output terminals 9 on the surface of the corresponding current sensor body 2, achieving rapid terminal docking. Finally, the quick-connect connector 34 allows for more convenient connection to external testing equipment, enabling batch testing of current sensors.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0046] During operation, firstly, multiple sets of current sensor bodies 2 are placed in their corresponding placement slots 5. Then, the drive motor 421 is started, driving the drive screw 422 to rotate. The rotation of the drive screw 422 causes the drive block 423 and the positioning plate 412 to slide synchronously to one side, allowing the positioning plate 412 to slide on the surface of the support rod 411. As the positioning plate 412 slides, the positioning rods 414 slide on the inner surface of the inclined sliding groove 413. Limited by the inclined sliding groove 413, the positioning rods 414 on both sides slide synchronously to opposite sides. The limiting block 432 at the bottom of the positioning rod 414 slides within the limiting groove on the surface of the limiting plate 431. As the positioning rods 414 slide, the positioning rods 414 on both sides slide to the bottom of the current sensor body 2. In the mounting slots 8 on both sides of the mounting base 7, the current sensor body 2 is clamped and positioned by the positioning rods 414 on both sides. The multiple positioning plates 412 are connected by the support plate, so that the multiple current sensor bodies 2 can be clamped and positioned synchronously. Then, by starting the docking cylinder 31, the connecting plate 32, the detection terminal 33 and the connecting rod 35 are driven to slide synchronously. The sliding of the connecting rod 35 will cause the multiple connecting plates 32 and the detection terminal 33 to slide synchronously, so that the detection terminal 33 slides into the signal output terminal 9 to achieve connection. Then, it is connected to the external testing equipment through the quick connector 34. Finally, a current-carrying wire or a current-carrying copper plate is passed through the opening on the surface of the current sensor body 2. After power is applied, the multiple current sensors are batch tested by the testing equipment.
