[0001] The utility model belongs to the technical field of inductance withstand voltage testing, and particularly relates to an inductance withstand voltage tester. Background Art

[0002] An inductor is a two-terminal circuit element that can convert electrical energy into magnetic energy and store it. Generally, it consists of a bobbin, a winding, a shielding cover, a packaging material, a magnetic core or an iron core, etc. When an inductor is produced, it needs to be subjected to a withstand voltage test to ensure its normal working performance.

[0003] Currently, when testing the withstand voltage of an inductor, usually a staff member holds a test probe or a probe to contact the inductor pin for detection. However, this is likely to cause unstable contact due to the shaking of the staff member's hand, resulting in poor contact and affecting the test accuracy. Summary of the Utility Model

[0004] In order to overcome the above defects, the utility model provides an inductance withstand voltage tester, which solves the problem that when a staff member holds a test probe or a probe to contact the inductor pin for detection, it is easy to cause unstable contact due to the shaking of the staff member's hand, thus affecting the test accuracy.

[0005] To achieve the above object, the utility model provides the following technical solution: an inductance withstand voltage tester, including a base, a plurality of support blocks are connected below the base, a chute is opened on the base, a fixing plate is connected inside the base, a hinge is connected to the base, a tester main body is rotatably installed on the base through the hinge, a display screen is installed on the tester main body, a knob is arranged on the tester main body, an electrode wire is connected to the tester main body, the tester main body is electrically connected to a test seat through the electrode wire, and a motor is installed on the fixing plate;

[0006] An output shaft of the motor is connected to a threaded rod, a moving block is installed on the threaded rod, a threaded sleeve is installed on the moving block, a hinge rod is rotatably connected to the moving block through a pin shaft, one end of the hinge rod is rotatably connected to a connecting block through a pin shaft, a plurality of pin holes are arranged on the test seat, a groove is opened inside the test seat, a spring is connected inside the groove, and one end of the spring is connected to a clamping plate.

[0007] As a further solution of the utility model: the threaded rod is rotatably connected inside the chute, the threaded sleeve is in threaded cooperation with the threaded rod, and the connecting block is connected to the lower part of the tester main body.

[0008] As a further solution of the utility model: there are four support blocks in total, which are evenly distributed in a rectangular array, an anti-slip pad is connected below the support blocks, and anti-slip patterns are arranged below the anti-slip pad.

[0009] As a further solution of the present utility model: a sloping plate is connected to the base, and guiding grooves are formed on the two side walls of the sliding groove.

[0010] As a further solution of the present utility model: guiding blocks are connected to the two sides of the moving block, and the guiding blocks are designed in a T shape and slide in the guiding grooves.

[0011] As a further solution of the present utility model: the clamping plate is integrally U-shaped and one end slides in the groove, and an inclined surface is arranged above the clamping plate, and a rubber pad is connected to the clamping plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For this inductance withstand voltage tester, by arranging the clamping plate, the groove, the spring and the pin hole, the staff can place the inductance between the two clamping plates. During the placement process, the inductance will push the clamping plate through the inclined surface of the clamping plate, so that the clamping plate can slide in the groove and at the same time stretch the spring, thereby expanding the distance between the two clamping plates, enabling the inductance pins to be inserted into the pin holes. And the spring's resilience will drive the clamping plate to move, so that the two clamping plates can clamp and fix the inductance, preventing the inductance from shaking and affecting the test accuracy. There is no need for the staff to hold the probe for testing, improving the accuracy and stability of the test data.

[0014] 2. For this inductance withstand voltage tester, by arranging the threaded rod, the threaded sleeve, the moving block, the hinge rod and the tester main body, when the motor rotates the threaded rod, the moving block can move along the sliding groove through the threaded fit between the threaded sleeve and the threaded rod. When the moving block moves, both ends of the hinge rod will rotate, thereby pushing the tester main body through the hinge rod, enabling the tester main body to rotate around the hinge as the center, thus adjusting the overall angle of the tester main body, enabling staff of different heights to view the test data at different angles, and improving the applicability and practicality of this withstand voltage tester.

[0020] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.

[0021] As Figures 1-4 shown, the present utility model provides a technical solution: an inductance withstand voltage tester, including a base 1, a plurality of support blocks 2 are connected below the base 1, there are four support blocks 2 in total and they are evenly distributed in a rectangular array, an anti-slip pad 21 is connected below the support block 2, and anti-slip patterns are provided below the anti-slip pad 21. The friction with the workbench is increased through the anti-slip pad 21 below the support block 2, so as to avoid the sliding of the base 1 when the tester main body 6 rotates, and the stability of the placement of the base 1 is improved.

[0022] A slide groove 3 is opened on the base 1, a fixed plate 4 is connected inside the base 1, a slope-shaped plate 22 is connected to the base 1, and guide grooves 23 are opened on the two side walls of the slide groove 3. When the tester main body 6 rotates to the lowest angle, it will contact the slope-shaped plate 22, so as to prevent the tester main body 6 from continuing to rotate through the slope-shaped plate 22, limit the lowest working angle, and avoid the angle between the hinge rod 15 and the moving block 13 being too small to cause the tester main body 6 to be unable to rotate.

[0023] A hinge 5 is connected to the base 1, the tester main body 6 is rotatably installed on the base 1 through the hinge 5, a display screen 7 is installed on the tester main body 6, a knob 8 is arranged on the tester main body 6, an electrode wire 9 is connected to the tester main body 6, the tester main body 6 is electrically connected to a test seat 10 through the electrode wire 9, a motor 11 is installed on the fixed plate 4, the output shaft of the motor 11 is connected to a threaded rod 12, a moving block 13 is installed on the threaded rod 12, a threaded sleeve 14 is installed on the moving block 13, the threaded rod 12 is rotatably connected in the slide groove 3, the threaded sleeve 14 is in threaded cooperation with the threaded rod 12, and a connecting block 16 is connected to the lower part of the tester main body 6. By rotating the threaded rod 12, the moving block 13 can move along the threaded rod 12 through the threaded sleeve 14, so as to push the tester main body 6 to rotate through the rotating hinge rod 15, enabling the staff to view the test data at different angles.

[0024] A hinge rod 15 is rotatably connected to the moving block 13 through a pin shaft. Guide blocks 24 are connected to both sides of the moving block 13. The guide blocks 24 are designed in a T shape and slide in the guide grooves 23. When the moving block 13 moves along the threaded rod 12, the guide blocks 24 will slide in the guide grooves 23, thereby guiding and restricting the movement of the moving block 13, enabling the moving block 13 to move smoothly.

[0025] One end of the hinge rod 15 is rotatably connected to a connection block 16 through a pin shaft. A plurality of pin holes 17 are provided on the test seat 10. A groove 18 is formed in the test seat 10. A spring 19 is connected in the groove 18. One end of the spring 19 is connected to a clamping plate 20. The clamping plate 20 is integrally U-shaped and one end slides in the groove 18. And an inclined surface is provided above the clamping plate 20. A rubber pad 25 is connected to the clamping plate 20. When the clamping plate 20 contacts the inductor, the rubber pad 25 will be squeezed, prompting the rubber pad 25 to be in close contact with the inductor, thereby improving the clamping stability and preventing the inductor from moving and affecting the test accuracy.

[0026] The working principle of the present utility model is as follows:

[0027] The staff places the inductor between the two clamping plates 20. During the placement process, the inductor will push the clamping plate 20 to move through the inclined surface of the clamping plate 20, prompting the distance between the two clamping plates 20 to expand, so that the inductor pins can be inserted into the pin holes 17. When the clamping plate 20 moves, the spring 19 will be stretched, and then the spring 19 will drive the clamping plate 20 to move through its resilience, enabling the two clamping plates 20 to clamp and fix the inductor to prevent the inductor from shaking and affecting the test accuracy. The information obtained from the test is displayed on the display screen 7. The staff can start the motor 11 to rotate the threaded rod 12, enabling the moving block 13 to move along the threaded rod 12 through the threaded sleeve 14. When the moving block 13 moves, both ends of the hinge rod 15 will rotate, thereby pushing the tester main body 6 to rotate through the hinge rod 15 to adjust the overall angle of the tester main body 6, so that staff of different heights can view the test data at different angles.
