The position of the clamping block 13 is adjustable, which can meet the clamping requirements of the test pieces of different shapes and sizes.

[0045] The back of the mounting base 1 also includes a detection input interface 14 and a detection output interface 15. The top surface of the mounting base 1, located on one side of the heat sink 12, also features an input / output control switch 16 and an isolation switch 17.

[0046] In this embodiment, the air outlet can be used as a mounting hole for the clamping block 13 on the one hand, and as a heat dissipation hole on the other hand. By controlling the start and stop of the heat dissipation fan 11, the heat dissipation requirements during the debugging of different modules can be met.

[0047] like Figure 2 As shown, the support frame 2 includes a support base and a guide rod 21. In this embodiment, the support base includes two vertical plates 22, a first horizontal plate 23, a second horizontal plate 24, and a third horizontal plate 25. The two vertical plates 22 are spaced apart, and the bottom of the vertical plates 22 is connected to one side of the top surface of the mounting base 1. The first horizontal plate 23, the second horizontal plate 24, and the third horizontal plate 25 are all connected between the two vertical plates 22. The first horizontal plate 23 mainly serves as a connector and reinforcement plate. The first horizontal plate 23 is connected to the bottom of the vertical plates 22, the second horizontal plate 24 is connected to the top of the vertical plates 22, and the third horizontal plate 25 is connected to the top side of the vertical plates 22.

The top end of the guide rod 21 is connected to the second horizontal plate 24, and the bottom end of the guide rod 21 is connected to one side of the top surface of the mounting base 1. In this embodiment, there are two guide rods 21, and one side of the pressure plate 3 is slidably connected to the guide rods 21.

[0048] like Figure 3 As shown, the telescopic mechanism 4 includes a connecting frame 41, a crank handle 42, a connecting plate 43, and a push rod 44. One side of the connecting frame 41 is connected to the third horizontal plate 25 of the support frame 2. The other side of the connecting frame 41 has a hinge point at the top and a sleeve at the bottom. One end of the crank handle 42 is rotatably connected to the hinge point.

The bottom end of the connecting plate 43 is connected to the push rod 44, and the push rod 44 is slidably connected within the sleeve. The other end of the crank handle 42 is a handheld end. By rotating the crank handle 42 up and down, the push rod 44 can be driven to move up and down along the sleeve, thereby achieving the up and down movement of the pressure plate 3 along the guide rod 21.

[0049] The pressing plate 3 is a flat plate, and the bottom surface of the pressing plate 3 is made of magnet or iron, which can achieve magnetic attraction with the probe detection module 5.

[0050] In this embodiment, the probe detection module 5 is connected to the bottom of the pressure plate 3 through magnetism. One or more probe detection modules 5 can be connected to the bottom of the pressure plate 3 as needed. The pressure plate 3 is controlled to move up and down by the telescopic mechanism 4, driving the probe detection module 5 to effectively contact the detected part fixed on the mounting base 1. The detected part is fixed on the top of the mounting base 1 according to the position of the probe detection module 5. The probe detection module 5 is in point contact with the detected part, thereby realizing the transmission of the detection signal and realizing detection.

[0051] This embodiment utilizes one or more magnetic probe detection modules 5 to adjust the contact position of the probe detection modules 5, adapting to different module interface positions and ensuring effective contact of the probes 52. This utility model meets the testing and debugging requirements of different power module models, reduces the number of specialized testing equipment, effectively reduces equipment failure rates, and provides a universal testing method, reducing the operational requirements for test personnel.

The fixing block 53 is connected inside the housing 51 and near the bottom opening. The probe 52 is connected to the fixing block 53. The magnet 55 is connected to the top of the housing 51.

[0054] The probe 52 is slidably connected to the fixed block 53. A spring 56 is sleeved on the outside of the probe 52, and the two ends of the spring 56 are respectively connected to the probe 52 and the fixed block 53. Under normal circumstances, due to the presence of the spring 56, the probe 52 is in a soft connection state. When the probe 52 contacts the object to be tested, the spring 56 can be compressed. The spring 56 has a rebound force, allowing the bottom of the probe 52 to adaptively contact the object to be tested. Due to the presence of the spring 56, even if the probe 52 is subjected to a large downward force, there will be a buffer to prevent the probe from breaking.

[0055] The probe detection module 5 further includes a wire pressing plate 57, which is connected to the interior of the housing 51. The side of the housing 51 includes a wire hole. The wire pressing plate 57 is used to fix the signal wire connected to the probe 52, and the signal wire is led out through the side wire hole.

[0056] The magnet 55 is disc-shaped and is connected to the top of the housing 51 by bolts through a connecting column. The magnet 55 is used to quickly fix the probe detection module 5. The cover 54 can be made of transparent acrylic material to cover the probe 52 and the fixing block 53 and also serve as an observation window.

[0057] In this embodiment, the spring 56 is provided to enable the probe 52 to elastically contact the detected object, thereby achieving effective contact and protecting the probe 52 .

[0058] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
