Description

Technical Field

[0001] This utility model relates to the field of inductor testing technology, and in particular to an inductor testing device. Background Technology

[0002] Inductors, commonly referred to simply as inductors, are one of the most commonly used basic electronic components. There are many types and shapes of inductors. The quality of an inductor can be tested with a multimeter. However, because the pin configurations of through-hole inductors differ—some inductors have parallel pins, while others have pins at 180°—testing inductors requires manually connecting the inductor's pins to the multimeter probes, or bending the pins to a fixed angle for testing on a testing device. This method is inconvenient and unsuitable for large-scale testing. Utility Model Content

[0022] Please refer to Figure 1-4 An inductor testing device includes a base plate 1, a pad 11 disposed on the top of the base plate 1, a test strip 2 disposed on the top of the pad 11, and a clamping mechanism 3 disposed on the base plate 1. The inductor to be tested is placed on the pad 11. There are two test strips 2, which are respectively connected to the two probes of a multimeter. The test strips 2 are arc-shaped, and the two leads of the inductor to be tested are respectively placed on the top of the two test strips 2. The clamping mechanism 3 includes a fixed base 31 at the top of the base plate 1, a fixed column 32 at the top of the base plate 1, an end face cam 33 rotatably mounted on the fixed base 31, a pressure plate 34 slidably mounted on the fixed column 32, and a pressure strip 35 at one end of the pressure plate 34. The end face cam 33 is slidably connected to the pressure plate 34. Rotating the end face cam 33 can drive the pressure plate 34 to move on the fixed column 32. At the same time, the pressure strip 35 will press or release the inductor pins placed on the pad 11, which facilitates quick testing of the inductor.

[0023] The top of the fixed base 31 is provided with a pin 311, and the bottom of the end face cam 33 is provided with an arc-shaped groove 330. The pin 311 matches the arc-shaped groove 330. The pin 311 restricts the rotation range of the end face cam 33, so that the end face cam 33 rotates within a fixed area.

[0024] A positioning post 312 is provided at the top of the fixed base 31, and a circular hole is provided at the center of the end face cam 33. The circular hole matches the positioning post 312. A screw 331 is rotatably mounted on the end face cam 33, and the screw 331 is threadedly connected to the positioning post 312. Under the constraint of the screw 331, the end face cam 33 rotates horizontally on the fixed base 31.

[0025] The end face cam 33 is generally semi-circular, the top surface of the end face cam 33 is an inclined surface 332, one side of the end face cam 33 is a plane, and a handle 333 is provided on the outer surface of the end face cam 33.

[0026] The pressure plate 34 is Y-shaped, with a waist-shaped through hole 341 in the middle. The fixing post 32 is slidably disposed in the waist-shaped through hole 341. The fixing post 32 is fitted with a first gasket 321 and a second gasket 322. The first gasket 321 and the second gasket 322 are located on the top and bottom surfaces of the pressure plate 34, respectively. A fixing nut 323 is provided at the top of the fixing post 32. A first spring 324 is fitted on the outer surface of the fixing post 32. One end of the first spring 324 is located on the top surface of the base plate 1, and the other end is located on the bottom surface of the second gasket 322.

[0027] A step 342 is provided at the bottom of one end of the pressure plate 34. The step 342 contacts the outer circle of the end face cam 33. The bottom of one end of the end face cam 33 slides in contact with the inclined surface 332 of the end face cam 33.

[0028] One end of the pressure plate 34 is provided with a transverse through groove 343, which is connected to the waist-shaped through hole 341. A pin 344 is provided in the transverse through groove 343. The pin 344 includes a cylindrical section 3441 and a vertical section 3442. A second spring 345 is sleeved on the outer surface of the cylindrical section 3441. The second spring 345 is in a compressed state.

[0029] The fixed column 32 is provided with a sloping groove 325, which is vertically arranged, and the end of the sloping groove 325 near the pressure strip 35 is wider than the other end. The vertical section 3442 can move within the sloping groove 325.

[0030] The pressure strip 35 is arc-shaped, and its shape matches the test strip 2. An anti-slip pad is provided at the bottom of the pressure strip 35.

[0031] like Figure 1 By rotating the end face cam 33 clockwise using the handle 333, guided by the rising section of the inclined surface 332, one end of the pressure plate 34 near the end face cam 33 tilts upward, while the other end of the pressure plate 34 presses downward, causing the pressure strip 35 to press the inductor leads onto the test strip 2. Conversely, by rotating the end face cam 33 counterclockwise, guided by the inclined surface 332, one end of the pressure plate 34 moves downward, while the other end of the pressure plate 34 causes the pressure strip 35 to move upward, releasing the inductor leads. Continue rotating the end face cam 33 counterclockwise. The step 342 contacts the plane on one side of the end face cam 33. Under the elastic force of the spring 345, the pressure plate 34 moves horizontally towards the end face cam 33. The pressure plate 35 moves away from the test strip 2, making it easier to pick up and place the inductor. Then rotate the end face cam 33 clockwise. The step 342 contacts the outer circle of the end face cam 33. The end face cam 33 presses against the step 342. The pressure plate 34 moves horizontally closer to the test strip 2. Repeat the above steps to repeatedly press or release the inductor pins. The operation is convenient and quick.
