Description

Technical Field

[0001] The utility model relates to the technical field of inductance testing, in particular to an inductance component testing device. Background Art

[0002] Inductance is a lumped electrical parameter that reflects the effect of magnetic field changes on circuits. Its functions include filtering, oscillation, delay, and trapping. In electronic circuits, inductors act on AC current limits and, together with resistors or capacitors, can form high-pass or low-pass filters, phase-shifting circuits, and resonant circuits. Transformers can perform AC coupling, voltage and current conversion, and impedance transformation. Therefore, the performance parameters of inductor components, such as inductance, quality factor (Q value), and loss tangent (D value), have a significant impact on the overall performance of the circuit. The continuous miniaturization, lightweighting, and high-frequency trends of electronic products are placing higher demands on the testing of inductor components. Existing inductor component testing equipment can increase the difficulty and complexity of testing inductor components due to the long distance between the test bench and the operator. This not only reduces testing efficiency but also increases the risk of operational errors.

[0003] In view of the above problems, the present invention proposes an inductor component testing device. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 5 In order to solve the problem that when testing inductor components using existing inductor component testing devices, the test bench is far away from the operator, which may increase the difficulty and complexity of the operation, thereby reducing the test efficiency and increasing the risk of operational errors, the following preferred technical solutions are provided:

[0022] A device for testing an inductor component comprises a mounting base 1 and a body 2 mounted on the upper end of the mounting base 1, a test body 3 being mounted inside the body 2, a test bench 4 being provided at the lower end of the test body 3, a guide rail body 5 being provided at the lower end of the test bench 4, a slider body 6 being slidably connected to the outer wall of the guide rail body 5, the slider body 6 being fixedly connected to the test bench 4, a threaded rod 7 being threadedly connected to the inner wall of the slider body 6, one end of the threaded rod 7 being fixedly connected to a motor 8, a first fixing groove 9 and a second fixing groove 10 being provided on the upper wall of the guide rail body 5, a fixing assembly 11 being fixedly connected to the top of the cavity of the slider body 6, when the fixing assembly 11 is on the inner wall of the second fixing groove 10, the positions of the test bench 4 and the test body 3 correspond, and when the fixing assembly 11 is on the inner wall of the first fixing groove 9, the test bench 4 abuts against the inner edge of the cavity of the mounting base 1.

[0023] The fixing assembly 11 includes a fixing block 111 at one end fixedly connected to the top of the cavity of the slider body 6. The fixing block 111 has a hemispherical structure, and the fixing block 111 is divided into a straight end and a curved end. The fixing block 111 is connected to the slider body 6 through the straight end. A movable groove 112 is provided on the inner wall of the curved end of the fixing block 111. A sliding rod 113 is slidably connected to the inner wall of the movable groove 112. The end of the sliding rod 113 away from the movable groove 112 is fixedly connected to the inner wall of the straight end of the fixing block 111. The outer wall of the sliding rod 113 is covered with an elastic element 114. The two ends of the elastic element 114 are fixedly connected to the inner wall of the fixing block 111. The fixing block 111 is a component made of rubber material. The diameter of the fixing block 111 is larger than the inner diameter of the first fixing groove 9 and the second fixing groove 10.

[0024] Specifically, when conducting a test, the motor 8 is driven, and the motor 8 is used to drive the threaded rod 7 to rotate, and the threaded rod 7 is used to drive the slider body 6 to move, so that the slider body 6 drives the test bench 4 to move through the guide rail body 5 until it moves to abut the edge of the cavity of the mounting base plate 1. At this time, the test bench 4 is close to the staff, and the inductor component can be easily placed on the test bench 4. Thereafter, the threaded rod 7 is used to drive the slider body 6 back to its original position, and the test bench 4 is driven again to be at the lower end of the test body 3. The test body 3 is used to test the change of current in the inductor element. The operation is convenient, which solves the problem that when the existing inductor component testing device tests the inductor component, the test bench is at a long distance from the staff, which may increase the difficulty and complexity of the operation, not only reducing the test efficiency, but also increasing the risk of operational errors.

[0025] When the test bench 4 corresponds to the position of the test body 3, the fixing component 11 is in the inner wall of the second fixing groove 10, and the test bench 4 abuts against the inner edge of the cavity of the mounting base 1, the fixing component 11 is in the inner wall of the first fixing groove 9. When the slider body 6 drives the fixing component 11 to move, the fixing block 111 will disengage from the first fixing groove 9 or the second fixing groove 10. At this time, the arc surface end of the fixing block 111 is deformed, fits the upper wall of the guide rail body 5 and moves, and drives the sliding rod 113 to move toward the inner wall of the movable groove 112, and the elastic element 114 will be pressed. When the fixing component 11 moves to the upper end of the first fixing groove 9 or the second fixing groove 10 again, the reaction force of the elastic element 114 and the elasticity of the fixing block 111 itself will cause the fixing block 111 to lock tightly the inner wall of the first fixing groove 9 or the second fixing groove 10, thereby ensuring the stability of the test bench 4 at the lower end of the test body 3 and abutting against the inner edge of the cavity of the mounting base 1, and the effect is significant.
