Description

Technical Field

[0001] This utility model belongs to the technical field of voltage-type Hall sensor testing fixtures, and in particular relates to a rapid testing fixture for voltage-type Hall sensors. Background Technology

[0002] High-voltage Hall effect sensors typically require leakage current testing to ensure their safety under high-voltage conditions. This testing helps verify whether the sensor has current leakage issues under high-voltage conditions, thereby preventing potential safety risks and performance problems.

[0003] However, during testing, alligator clips are usually manually used for connection. Existing high-voltage Hall sensors generally have multiple connectors. Wearing insulated gloves and manually operating multiple alligator clips to hold the ports is time-consuming and the ports are prone to slipping when connected to the alligator clips, potentially damaging the product during testing. Furthermore, to ensure the size of the high-voltage Hall current sensor, the side connectors may be stacked in multiple rows. To facilitate the testing of high-voltage Hall current sensors with such side-stacked connectors, a fast and convenient testing fixture for voltage Hall sensors is needed. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a rapid testing fixture for voltage-type Hall sensors, which effectively solves the problem in the prior art where the connectors of high-voltage Hall sensors with multiple rows stacked on the side are inconvenient for testing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rapid testing fixture for a voltage-type Hall sensor includes a fixed base, a lower pressing part located on the upper part of the fixed base, and a side pressing part located on the side of the fixed base. The upper side of the fixed base is provided with a test slot. Both the lower pressing part and the side pressing part include a mounting base, a sliding guide plate, a first hinge rod, a second hinge rod, an operating handle, a sliding guide rod, a lower pressing plate, and a test probe. The operating handle is fixedly connected to the first hinge rod. The two ends of the first hinge rod are respectively hinged to the mounting base and one end of the second hinge rod. The other end of the second hinge rod is hinged to the sliding guide rod. The sliding guide plate is fixedly installed on the mounting base. The sliding guide rod is slidably connected to the sliding guide plate. The lower pressing plate is fixedly connected to the lower end of the sliding guide rod. The test probe is installed on the side of the lower pressing plate near the workpiece. By using the operating handle, the first hinge rod and the second hinge rod are driven, thereby driving the sliding guide rod to slide downward along the sliding guide plate. At this time, the test probe on the lower pressing plate can contact the product under test, thus facilitating voltage testing.

[0006] Furthermore, there are two hinge rods, and the two ends of the two hinge rods are respectively rotatably connected to the sliding guide rod and the hinge rod.

[0007] Furthermore, a support plate is provided at the rear of the fixed base, the pressing part is installed on the upper part of the support plate, and the side pressing part is fixedly installed on the fixed base.

[0008] Furthermore, the edge of the lower pressure plate is provided with a protective plate.

[0009] Furthermore, the pressing part includes five test probes, which are respectively arranged on the left and right sides of the lower part of the pressing plate;

[0010] The side pressure section includes a test probe, which is located on the side of the side pressure section near the workpiece.

[0011] Furthermore, two test probes are provided on the left side of the lower part of the pressure plate, and three test probes are provided on the right side of the lower part of the pressure plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes a test slot on the upper side of a fixed base, formed by the cooperation of a downward pressing part and a side pressing part, to fix the high-voltage Hall current sensor under test. At the same time, the test probe can quickly connect multiple connectors on the side of the high-voltage Hall current sensor. Compared with the traditional alligator clip method, this invention is faster and more convenient, and it eliminates the need for manual connection of live wires, making the operation safer.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] like Figure 1 As shown, a rapid testing fixture for a voltage-type Hall sensor includes a fixed base 1, a pressing part 2 located on the upper part of the fixed base 1, and a side pressing part 3 located on the side of the fixed base 1. A test slot 11 is provided on the upper side of the fixed base 1. The test slot 11 is opened according to the bottom contour of the product to be tested, and the test slot 11 is slightly larger than the bottom contour of the product. Both the pressing part 2 and the side pressing part 3 include a mounting base 21, a sliding guide plate 22, a first hinge rod 23, a second hinge rod 24, an operating handle 25, a sliding guide rod 26, a pressing plate 27, and a test probe 28. The operating handle 25 is integrally fixedly connected to the first hinge rod 23. The upper part of the mounting base 21 is provided with a hinge part that slightly protrudes from the mounting base 21. The upper end of hinge rod 23 is hinged to the hinge part by means of a through-pin. The other end of hinge rod 23 is hinged to the upper end of hinge rod 24 by means of a through-pin. The lower end of hinge rod 24 is hinged to the upper end of sliding guide rod 26 by means of a through-pin. The mounting base 21 has screw holes. The sliding guide plate 22 is fixedly mounted on the mounting base 21 by screws. The front side of the mounting base 21 has a slide rail. The sliding guide rod 26 is slidably connected in the slide rail. The lower pressure plate 27 is fixedly mounted to the lower end of the sliding guide rod 26 by screws. The lower pressure plate 27 has mounting holes. The test probe 28 is inserted into the mounting holes and the lower end of the test probe 28 protrudes from the lower side of the lower pressure plate 27.

[0019] In this embodiment, there are two hinge rods 24. The two ends of the two hinge rods 24 respectively clamp the ends of the sliding guide rod 26 and the hinge rod 23 and are hinged together by the through pins.

[0020] In this embodiment, a support plate 4 is fixedly installed on the rear side of the fixed base 1 by screws. The mounting base 21 of the lower pressing part 2 is fixedly connected to the upper part of the support plate 4 by screws. The side pressing part 3 is fixedly installed on the upper side of the fixed base 1 by screws. A test probe 28 is fixedly connected to the moving end of the pressure measuring part 3. The test probes 28 of the lower pressing part 2 and the side pressing part 3 are both facing the test slot 11.

[0021] In this embodiment, the edge of the lower pressure plate 27 is fixed with a protective plate 5 by adhesive bonding.

[0022] It should be noted that the voltage-type Hall sensor of the product under test has two left-side terminals 6 of the same height on the left side, and four right-side terminals in total. Three of the right-side terminals are of the same height, and for ease of description, they are referred to as the first right-side terminal 7. The remaining right-side terminal is slightly lower than the others, and for ease of description, it is referred to as the second right-side terminal 8. The installation positions of the test probes 28 are adapted to the left-side terminals 6, the first right-side terminal 7, and the second right-side terminal 8, respectively. Specifically, a total of 5 test probes 28 are installed on the lower side of the pressure plate 27, of which 2 are for... The test probe 28 is matched with the position of the left terminal 6, and the installation positions of the remaining three test probes are matched with the position of the right first terminal 7. That is, by adjusting the length of each test probe 28 extending out of the lower pressure plate 27, during the descent of the lower pressure plate 27, a total of 5 test probes 28 on the lower side of the lower pressure plate 27 will simultaneously contact the left terminal 6 and the right first terminal 7. Furthermore, the test probe 28 fixedly connected to the moving end of the side pressure part 3 is matched with the position of the right second terminal 8. When the side pressure part 3 is pushed, the test probe 28 will be driven to contact the right second terminal 8.

[0023] It should be further explained that the test probes 28 mentioned above are all high-current probes, specifically the 420*4820-H / dense-tooth high-current probe. They have a built-in spring that can be appropriately compressed after contacting the terminal of the product under test, so as to ensure that each test probe 28 can contact the corresponding terminal. This is existing technology and will not be described in detail here. Each terminal of the test probe 28 is connected to a probe cable for transmitting current and signal.

[0024] It should be further explained that the side pressure part 3 is a push-pull clamp of model CH-302-CR, which is fixed on the upper side of the fixed base 1, and its moving end is connected to the corresponding test probe 28.

[0025] In use, the upper ends of the test probes 28 are connected to the withstand voltage tester via wires. The voltage-type Hall sensor to be tested is placed in the test slot 11. By pressing down the operating handle 25 in the pressing part 2, the hinge rod 23 is rotated along the hinge joint between the hinge rod 23 and the mounting base 21, thereby driving the hinge rod 24 to push the sliding guide rod 26 downward. This causes the sliding guide rod 26 to move the lower pressure plate 27 and the test probes 28 closer to the connector of the voltage-type Hall sensor in the test slot 11, and the test probes 28 are aligned with the connector. The side pressure part 3 is then aligned with the connector on the side of the voltage-type Hall sensor using the same steps. At this point, the withstand voltage tester can be started to perform the test. After the test is completed, by lifting the operating handles 25 of the pressing part 2 and the side pressure part 3, the hinge rod 23 is rotated upward, thereby moving the lower pressure plate 27 and the test probes 28 upward, and the voltage-type Hall sensor in the test slot 11 can be removed.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
