The personal emotions and mental state of the staff will also have a significant impact on the detection accuracy and efficiency of products. In view of this, this application proposes a testing mechanism for a Hall current sensor. Content of the Utility Model

[0028] In this embodiment, a test component 6 for current testing is fixedly connected inside the fixing frame 20. A data processing device 7 electrically connected to the test component 6 is fixedly connected inside the base 1. Conductive sheets 401 are fixedly connected to the opposite sides of the first clamping plate 2 and the second clamping plate 4. The sensor body 19 is composed of a main body and pins, which is convenient for connecting the sensor body 19 to the test circuit of the test component 6 by contacting the conductive sheets 401 with the pins of the sensor body 19.

[0029] Among them, a rotating motor 8 is fixedly connected inside the base 1. The output end of the rotating motor 8 is fixedly connected to a rotating disk 9. A plurality of fixing plates 10 are fixedly connected to the top of the rotating disk 9, which is convenient for realizing the position switching of the fixing plates 10 by the rotation of the rotating disk 9. An adjusting component for adjusting the position of the sensor body 19 is provided inside the fixing plate 10.

[0030] In this embodiment, the adjusting component includes an electric push rod 16 fixedly connected inside the fixing plate 10. The output end of the electric push rod 16 is fixedly connected to a grasping head 17 for grasping the sensor body 19, which is convenient for the electric push rod 16 to cooperate with the grasping head 17 to realize the adjustment of the lateral position of the sensor body 19.

[0031] Embodiment 2: The auxiliary component includes two limit frames 14 movably connected to the inner side of the fixed plate 10 and arranged symmetrically.

[0033] The beneficial effects of the above embodiments are as follows:

[0034] For the testing mechanism of this Hall current sensor, when the sensor body 19 abuts against the abutting block 18, the first clamping plate 2 and the second clamping plate 4 can be rotated so that the conductive sheets 401 on the first clamping plate 2 and the second clamping plate 4 respectively contact the pins on both sides of the sensor body 19, thus facilitating the cooperation with the operation of the testing component 6 and the data processing device 7 to realize the testing of the sensor body 19, and the data processing device 7 can realize data recording and qualified judgment, so as to effectively improve the testing efficiency and reduce the labor cost;

[0035] During the testing process, the position of the fixed plate 10 can be switched by the rotation of the rotating disk 9. When the fixed plate 10 on which the sensor body 19 to be tested is placed corresponds to the position of the fixed frame 20, the front-back movement of the sensor body 19 can be restricted by the limit frame 14, and the electric push rod 16 can cooperate with the gripping head 17 to adjust the lateral position of the sensor body 19, so as to facilitate the automatic installation and positioning of the sensor body 19, further reducing the labor cost and enhancing the practical effect of the device.

[0036] The working principle of the above embodiments is as follows:

[0037] For the testing mechanism of this Hall current sensor, during use, the sensor body 19 to be tested can be placed inside the fixed plate 10, and the displacement motor 11 is driven to drive the bidirectional screw 12 to rotate, so that the displacement block 13 drives the limit frame 14 to move away from or close to one side along with the rotation of the bidirectional screw 12 until the limit frame 14 clamps the sensor body 19, playing a role in restricting its front-back movement;

[0038] When conducting tests, the rotation motor 8 can be operated to drive the rotating disc 9 to rotate, so as to facilitate the position switching of the fixing plate 10. When the fixing plate 10 with the sensor body 19 to be tested corresponds to the fixing frame 20 in position, the position of the grasping head 17 can be adjusted by operating the electric push rod 16, so as to adjust its horizontal position after the grasping head 17 grabs the sensor body 19; thus, it is convenient to push the sensor body 19 into the fixing frame 20 and make the pins on the sensor body 19 be on both sides of the abutting block 18.

[0039] After that, the clamping motor 3 can be operated to drive the second clamping plate 4 to rotate, and the second clamping plate 4 drives the first clamping plate 2 to rotate by the transmission of the transmission gear 5. Thus, the first clamping plate 2 and the second clamping plate 4 rotate synchronously and in opposite directions, and the conductive sheets 401 on the first clamping plate 2 and the second clamping plate 4 respectively contact the pins on both sides of the sensor body 19, so as to connect the sensor body 19 to the test circuit of the test component 6. Thus, the test of the sensor body 19 is realized by the operation of the test component 6 and the data processing device 7, and the data processing device 7 can realize data recording and qualified judgment, so as to effectively improve the test efficiency and reduce the labor cost.
