The dynamic and static parameter test module, the temperature characteristic test module and the electrothermal characteristic test module all include a connecting plate 4 for contacting the MOS tube and a connecting instrument for testing the MOS tube. Secondly, the temperature characteristic test module also includes a heating component for heating testing.
[0023] Secondly, a slide rail 2 is provided between different test stations, and a moving device 5 is provided on the slide rail 2, so that the test stations can be arranged along a straight line;
[0024] The moving device 5 is provided with a MOS tube fixing device 6, and the bottom of the MOS tube fixing device 6 is provided with an opening for allowing the bottom of the MOS tube to contact the test station. The moving device 5 is used to drive the MOS tube fixing device 6 to move on the slide rail 2, and the MOS tube fixing device 6 is used to clamp the MOS tube.
[0025] The above structure of the utility model mainly includes a base 1 and several test stations arranged on the base 1. Different test stations are used to test different functions of the MOS tube. A slide rail 2 is arranged between different test stations, and a moving device 5 is arranged on the slide rail 2. When the device is in use, the MOS tube is arranged in the MOS tube fixing device 6, and the entire MOS tube fixing device 6 is moved to one of the test stations by the moving device 5 for testing. After the test is completed, the MOS tube fixing device 6 is moved to the next station by the slide rail 2, and the tests are carried out in sequence. Through the above structure, there is no need to repeatedly take and install. Under the condition that the slide rail 2 is accurately installed, the slide rail 2 also assists the staff in positioning. There is no need to correct the left and right installation positions. It is only necessary to adjust the front and rear positions to reach the test station, which further provides convenience to the staff and improves work efficiency.
[0026] An exemplary embodiment of the utility model, the moving device 5 includes a supporting frame 8 and a pulley block 7, the supporting frame 8 is a frame structure that runs through the middle, the pulley block 7 is arranged on both sides of the supporting frame 8, an inner groove is opened on the inner side of the slide rail 2, and the pulley block 7 slides in the inner groove of the slide rail 2. Selecting such a sliding mode can prevent the pulley block 7 from falling off the slide rail 2.
[0027] In an exemplary embodiment of the utility model, the MOS tube fixing device 6 includes a support seat 9 and a pressing device arranged on the support seat 9, the pressing device is used for the setting of the MOS tube, and the bottom of the support seat 9 is provided with an opening for contacting with the connecting plate 4, wherein the support seat 9 and the support frame 8 can be connected by magnetic attraction for easy removal.
