Description

Technical Field

[0001] The present application relates to the technical field of inductance test fixtures, and specifically to an I-shaped inductance test fixture. Background Art

[0002] I-shaped inductors are mainly composed of a magnetic core, a winding group, and pins. During the production process, photoelectric testing of the core and pin conditions is required to eliminate defective products. When testing I-shaped inductors, a test probe is usually used to fully contact the pins of the I-shaped inductor for testing.

[0003] According to an I-shaped inductor test fixture disclosed in Chinese patent publication No. CN221528716U, the test holder includes a test seat, a limit seat, a test probe, a cover plate, and a separator. The test seat corresponds to the limit seat, and two test probes are provided on the side of the test seat corresponding to the limit seat. The two test probes are distributed in parallel, and there is a gap between the two test probes. The cover plate is pressed on the two test probes. The separator is located above the cover plate, and the separator corresponds to the gap between the two test probes. Two limit slots are provided on the side of the limit seat corresponding to the test seat. The limit slots are used to limit the pins of the I-shaped inductor, which can prevent the test probe from deflecting, correct the I-shaped inductor, greatly improve the test accuracy, and have a simple structure.

[0004] However, this patent still has certain shortcomings in actual use. Due to the different actual needs of customers and different production processes, the spacing of the I-shaped inductor pins is not the same. The position of the separator in this patent cannot be conveniently adjusted and changed according to the actual pin spacing. As a result, when the pin spacing difference is too large, deformation is likely to occur after adjustment through the fixed position separator, affecting the actual test accuracy and efficiency, resulting in a certain amount of optimization space for the actual operation method. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides an I-shaped inductor test fixture, which has the advantages of being able to change the position of the adjustment structure according to actual needs, thereby solving the disadvantage that the existing I-shaped inductor test fixture is inconvenient to adaptively adjust the position of the adjustment structure according to actual needs during operation.

[0006] To achieve the above objectives, the present application provides the following technical solution: an I-shaped inductance test fixture, comprising a base, a limit slider slidably connected to the top of the base, a fixed block fixed to the top of the base, an adjustment adapter component installed on the outer side of the limit slider, and a test component installed on the outer side of the fixed block;

[0013] Furthermore, the test probe body includes a square test end and a cylinder, and the outer side of the test end is fixedly connected to the end of the cylinder.

[0014] By adopting the above technical solution, the square test terminal can be limited to a certain extent through the installation groove, which is convenient for the normal implementation of the abutment test work.

[0015] Furthermore, the circular block can be inserted into the inner side of the corresponding trapezoidal hole, and the inner diameter of the trapezoidal hole is larger than the diameter of the circular block. The positions of the magnetic sheet and the metal sheet on the same side correspond to each other and can be adsorbed and fitted to each other.

[0016] By adopting the above technical solution, the circular block can move inside the corresponding trapezoidal hole when the cover block is pushed to move, so that the cover block can be adsorbed and positioned with the metal sheet.

[0017] Furthermore, the conical block is triangular, and the right side of the conical block is located in the middle between the opposite sides of the two test probe bodies. The test probe body is located between the opposite sides of the conical block and the auxiliary block.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] See also Figures 1 to 5 , the present application provides a technical solution: an I-shaped inductor test fixture, comprising a base 1, a limiting slider 3 being slidably connected to the top of the base 1, a fixed block 4 being fixed to the top of the base 1, an adjustment adapter component 500 being installed on the outer side of the limiting slider 3, and a test component 600 being installed on the outer side of the fixed block 4; through the coordinated use of the limiting slider 3, the fixed block 4, the adjustment adapter component 500 and the test component 600 at the top of the base 1, the position of the adjustment structure can be changed according to actual needs, so that the test work can be carried out more efficiently and conveniently, and it can also facilitate the operator to operate, and the fixture structure can be adapted and adjusted according to the I-shaped inductors with different pin spacings, so that the I-shaped inductors with different pin spacings can also be conveniently moved vertically to the test point, which facilitates the efficient testing work and improves the adaptability of the test fixture, thereby effectively improving the practicality of the I-shaped inductor test fixture.

[0033] It should be noted that an adjustment groove 201 is provided on the top of the base 1 for the limit slider 3 to slide, and two adjustment rods 202 are fixed on the inner side of the adjustment groove 201. The ends of the adjustment rods 202 pass through the left side of the limit slider 3, and the right side of the limit slider 3 can abut against the left side of the fixed block 4, so that the limit slider 3 can slide stably to the left side of the fixed block 4 through the two adjustment rods 202.

[0034] In this embodiment, the adjustment adapter component 500 is a structure for adjusting to adapt to pins with different spacings.

[0035] like Figure 1 、 Figure 2 and Figure 3 As shown, the adjustment adapter assembly 500 includes an adapter slot 501 provided at the top of the limit slider 3, an adapter block 502 slidably connected to the inner side of the adapter slot 501, an adjustment hole 503 provided at the top of the adapter block 502, a positioning bolt 504 passing through the inner side of the adjustment hole 503, a conical block 505 fixed to the right side of the adapter block 502, a pressure plate 506 fixed to the right side of the limit slider 3, an auxiliary block 507 fixed to the right side of the pressure plate 506, two placement slots 508 provided on the right side of the auxiliary block 507, an I-shaped inductor body 509 placed on the top of the conical block 505, and two pin bodies 510 fixed to the bottom of the I-shaped inductor body 509.

[0036] It should be noted that the right side of the adapter groove 501 is open, so that the adapter block 502 can slide normally on the inner side of the adapter groove 501, and the adapter block 502 slides on the outside of the positioning bolt 504 through the adjustment hole 503. The top of the limiting slider 3 is provided with an internal thread groove for the positioning bolt 504 to be threadedly connected. The bottom of the end of the positioning bolt 504 can abut against the top of the adapter block 502, so that the positioning bolt 504 can be connected to the inner thread of the internal thread groove, thereby playing a positioning role for the adapter block 502.

[0037] In this embodiment, the test assembly 600 is a structure used to facilitate the layout of the test structure.

[0038] like Figure 1 、 Figure 4 and Figure 5As shown, the test assembly 600 includes a cover block 601 abutting against the top of the fixed block 4, an extension plate 602 fixed to the right side of the cover block 601, two mounting grooves 603 opened between the cover block 601 and the opposite side of the fixed block 4, a test probe body 604 placed inside the mounting groove 603, four combination plates 605 respectively fixed to the front and back sides of the cover block 601 and the front and back sides of the fixed block 4, a circular block 606 fixed to the bottom of the top combination plate 605, a trapezoidal hole 607 opened at the top of the bottom combination plate 605, a magnetic sheet 608 fixed to the bottom of the top combination plate 605, and a metal sheet 609 fixed to the top of the bottom combination plate 605.

[0039] It should be noted that the test probe body 604 includes a square test terminal and a cylinder. The outer side of the test terminal is fixedly connected to the end of the cylinder. The square test terminal can be limited by the mounting groove 603 to facilitate the normal progress of the abutment test. The circular block 606 can be inserted into the inner side of the corresponding trapezoidal hole 607, and the inner diameter of the trapezoidal hole 607 is larger than the diameter of the circular block 606, so that the circular block 606 can move inside the corresponding trapezoidal hole 607 during the process of the cover block 601 being pushed and moved, thereby facilitating the opening of the cover block 601, and the movement of the circular block 606 inside the trapezoidal hole 607 will not affect the progress of the test. As long as the test terminal can abut against the pin body 510, the test can be carried out.

[0040] In addition, the positions of the magnetic sheet 608 and the metal sheet 609 on the same side correspond to each other and can be adsorbed and fitted to each other, so that the cover block 601 can be adsorbed and positioned with the metal sheet 609, thereby facilitating the opening of the cover block 601 to remove the test probe body 604. The conical block 505 is triangular in shape, and the right side of the conical block 505 is located in the middle between the opposite sides of the two test probe bodies 604, so that the pin body 510 separated by the conical block 505 can each be moved to the left side of the two test probe bodies 604.

[0041] At the same time, the test probe body 604 is located between the opposite side of the conical block 505 and the auxiliary block 507, and the top, bottom and left side of the placement groove 508 are all open. The outer side of the pin body 510 can abut against the right side of the pressure plate 506, so that the two pin bodies 510 of the I-shaped inductor body 509 can be separated by the conical block 505, and then enter the inner side of the corresponding placement groove 508 for auxiliary limiting, and finally abut against the right side of the pressure plate 506, so that the left side of the test probe body 604 is stably fitted with the pin body 510.

[0042] The working principle of the above embodiment is:

[0043] When testing the I-shaped inductor body 509, the position of the tapered block 505 is adjusted according to the actual spacing between the two pin bodies 510, and the positioning bolt 504 is loosened so that it no longer presses on the top of the adapter block 502. The adapter block 502 is slid to move it inside the adapter groove 501, so that the position of the tapered block 505 can be changed, so that it is convenient to make adaptive adjustments according to the pin bodies 510 with different spacings. The limiting slider 3 is moved to the left side of the fixed block 4, and the I-shaped inductor body 509 is respectively inserted into the inner sides of the two placement grooves 508 through the front and back sides of the tapered block 505, so as to limit the position of the pin body 510 to a certain extent. The limiting slider 3 is slided so that the left side of the test probe body 604 abuts against the right side of the pin body 510, and the test work can be carried out normally.

[0044] Compared with the existing technology, the I-shaped inductor test fixture, through the coordinated use of the limit slider 3, the fixed block 4, the adjustment adapter component 500 and the test component 600 on the top of the base 1, can change the position of the adjustment structure according to actual needs, so that the test work can be carried out more efficiently and conveniently, and it is also convenient for the operator to operate. The fixture structure is adapted and adjusted according to the I-shaped inductors with different pin spacings, so that the I-shaped inductors with different pin spacings can also be conveniently moved vertically to the test point, which facilitates the efficient testing work and improves the adaptability of the test fixture, thereby effectively improving the practicality of the I-shaped inductor test fixture and solving the shortcoming of the existing I-shaped inductor test fixture that it is inconvenient to adaptively adjust the position of the adjustment structure according to actual needs during operation.
