Description

Technical Field

[0001] The utility model relates to the technical field of PMOS transistor detection, in particular to a PMOS transistor detection device. Background Art

[0002] A PMOS transistor, that is, a P-channel metal-oxide-semiconductor field-effect transistor, is an electronic device. A PMOS transistor has three main pins, namely a source (S), a gate (G), and a drain (D). In a PMOS transistor, current flows from the source to the drain. PMOS transistors are widely used in digital circuits and integrated circuits, especially in occasions where high impedance and low power consumption are required. PMOS and NMOS transistors can jointly form a complementary MOS integrated circuit (CMOS circuit), which is very common in digital circuits.

[0003] By connecting the probe of an oscilloscope to the input and output terminals of a PMOS transistor, the change of the waveform can be observed and analyzed. The change of the amplitude and frequency of the waveform helps to diagnose whether there is a problem with the PMOS transistor. A test auxiliary test bench is used in the test process. For example, the Chinese Patent Publication No. "CN221378060U" discloses a MOS transistor detection device, including a detection bench. A displacement adjustment mechanism is fixedly connected to the upper side of the detection bench. The upper end of the displacement adjustment mechanism is fixedly connected with a placement shell. A plurality of uniformly arranged placement grooves are opened at the front end of the upper side of the placement shell. A clamping mechanism is arranged in the placement shell, and the clamping mechanism extends into the placement grooves. A support frame is fixedly connected to the upper side of the detection bench. A first telescopic rod is fixedly connected to the upper side of the transverse end of the support frame. The lower end of the first telescopic rod penetrates through the support frame and is fixedly connected with a pressure relief mechanism.

[0004] For different types of PMOS transistors, there are differences in the pin pitch. Most of the existing test auxiliary benches can only detect specific types of PMOS transistors. Due to their inability to adapt to the pin pitches of various different types of PMOS transistors, their functions are relatively single in practical applications and cannot be widely applied to the detection requirements of various types of PMOS transistors. Summary of the Utility Model

[0008] Wherein, a driving component is arranged inside the base, and the driving component is used to drive the rotating shaft to rotate.

[0009] Furthermore, at least three jacks are arranged on the test seat. Conductive sheets are fixedly connected to the inner walls of the jacks. Guide grooves matching the jacks are arranged at the lower end of the rotating disk.

The two ends of the spring are respectively fixedly connected to the L-shaped clamping block and the inner wall of the mounting groove.

[0012] Furthermore, the driving component includes a first gear. The first gear is fixedly connected to the rotating shaft. A second gear is meshed and connected to one side of the first gear. The second gear is rotatably connected to the base. A positioning mechanism is further arranged on the rotating shaft.

[0013] Furthermore, the positioning mechanism includes a turntable. The turntable is fixedly connected to the rotating shaft.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1-5, a PMOS transistor detection device, including a base 1. The upper end of the base 1 is rotatably connected to a rotating shaft 11. The upper end of the rotating shaft 11 is fixedly connected to a rotating disk 12. A plurality of slots 13 are formed on the surface of the rotating disk 12.

The test seat 2 is fixedly connected to the rotating disk 12 through a locking mechanism 4. In this embodiment, different types of test seats 2 can be provided on the rotating disk 12 to adapt to the pitch of different PMOS transistor pins. During the operation of the present utility model, by rotating the rotating disk 12, a specific test seat 2 can be positioned above the energizing component 3. At this time, this test seat 2 is energized, while other test seats 2 are not energized. During the process of fixing the test seat 2 through the locking mechanism 4, the main purpose is to ensure the stable position of the test seat 2 on the rotating disk 12 and prevent it from falling due to vibration or other external forces during the detection process;

[0024] Among them, a driving component 5 is arranged inside the base 1. The driving component 5 is used to drive the rotating shaft 11 to rotate. In the present utility model, the driving component 5 drives the rotating shaft 11 to rotate, and then drives the rotating disk 12 to rotate, so that different test seats 2 on the rotating disk 12 are electrically connected to the energizing component 3. Through the design of driving the rotating shaft 11 to rotate by the driving component 5 and then driving the rotating disk 12 to rotate, it is ensured that different test seats 2 on the rotating disk 12 can be electrically connected to the energizing component 3 in sequence.

[0025] Furthermore, at least three jacks 21 are provided on the test seat 2. In this embodiment, different specifications of jacks 21 can be provided on multiple test seats 2 to adapt to different specifications of PMOS transistors. A conductive sheet 22 is fixedly connected to the inner wall of the jack 21. A guide groove 23 matching the jack 21 is provided at the lower end of the rotating disk 12. The conductive sheet 22 penetrates to the lower end of the test seat 2 and is located in the guide groove 23. During the operation of the present utility model, the pins of the PMOS transistor are inserted into the jacks 21. At this time, the conductive sheet 22 forms an electrical connection with the pins.

[0026] Further, the energized component 3 includes a mounting base 31. A plurality of conductive columns 32 are movably inserted into the mounting base 31. A pressing spring 33 is fixedly connected to the lower end of the conductive column 32. One end of the pressing spring 33 is fixedly connected to the mounting base 31. The upper end of the conductive column 32 is slidably connected to the guide groove 23. In this embodiment, a wiring port is provided on one side of the base 1, and the wiring port is electrically connected to the conductive column 32. Among them, the outside of the wiring port is connected to a detector through a wire. In the present utility model, when the test base 2 is located above the conductive column 32, at this time, the conductive column 32 abuts against the conductive sheet 22 through the pressing spring 33. During the process of the conductive column 32 abutting against the conductive sheet 22, a stable electrical connection is formed between them. In this way, the conductive column 32 can transmit power or signals to the pins of the PMOS transistor, and at the same time, it can also receive signals from the pins, and then detect the PMOS transistor through an external tester.

[0027] Among them, the locking mechanism 4 includes a mounting groove 41 provided on the rotating disk 12. An L-shaped block 42 is slidably connected in the mounting groove 41. A card slot 43 is provided at one end of the test base 2. One end of the L-shaped block 42 is clamped with the card slot 43. A spring 44 is provided in the mounting groove 41. Both ends of the spring 44 are fixedly connected to the L-shaped block 42 and the inner wall of the mounting groove 41 respectively. In the present utility model, after the L-shaped block 42 is inserted into the card slot 43, through the elastic force of the spring 44, the L-shaped block 42 is tightly fixed in the card slot 43, thereby fixing the test base 2. When it is necessary to replace the test base 2, by pressing the L-shaped block 42, it is separated from the card slot 43, and then the test base 2 can be taken out for replacement or maintenance.

[0028] In addition, the driving component 5 includes a first gear 51. The first gear 51 is fixedly connected to the rotating shaft 11. A second gear 52 is meshed and connected to one side of the first gear 51. The second gear 52 is rotatably connected to the base 1. A positioning mechanism 6 is also provided on the rotating shaft 11. In the present utility model, by rotating the second gear 52 to drive the first gear 51 to rotate, and then driving the rotating disk 12 to rotate, and positioning the rotating shaft 11 through the positioning mechanism 6, the test base 2 is ensured to be at the upper end of the energized component 3, ensuring the accurate electrical connection between the test base 2 and the conductive column 32.

[0029] In addition, the positioning mechanism 6 includes a turntable 61, which is fixedly connected to the rotating shaft 11. A positioning groove 62 corresponding to the slot 13 is provided on the surface of the turntable 61. One side of the base 1 is slidably inserted with a pull rod 63. One end of the pull rod 63 is fixedly connected with a positioning block 64, and the positioning block 64 is clamped with the positioning groove 62. A return spring 65 is arranged on the surface of the pull rod 63. In the present utility model, through the elastic force of the return spring 65, the positioning block 64 is pushed to be clamped with the positioning groove 62 to ensure the fixed position of the test seat 2. When it is necessary to rotate the rotating disk 12 to adjust the detection position, the operator pulls the pull rod 63 to separate the positioning block 64 from the positioning groove 62. After rotating to a new detection position, relying on the action of the return spring 65, the positioning block 64 will automatically be clamped with the positioning groove 62 at the new position, thus completing the precise positioning of the test seat 2 at the new position.

[0030] Working mode: During operation, first insert the pins of the PMOS transistor into the jack 21. At this time, the conductive sheet 22 forms an electrical connection with the pins. When the test seat 2 is located above the conductive column 32, the conductive column 32 abuts against the conductive sheet 22 through the compression spring 33. During the process of the conductive column 32 abutting against the conductive sheet 22, a stable electrical connection is formed between them. In this way, the conductive column 32 can transmit power or signals to the pins of the PMOS transistor, and can also receive signals from the pins. Then, the PMOS transistor is detected by an external tester. Through the elastic force of the return spring 65, the positioning block 64 is pushed to be clamped with the positioning groove 62 to ensure the fixed position of the test seat 2. When it is necessary to rotate the rotating disk 12 to adjust the detection position, the operator pulls the pull rod 63 to separate the positioning block 64 from the positioning groove 62. By rotating the second gear 52 to drive the first gear 51 to rotate, and then driving the rotating disk 12 to rotate. After rotating to a new detection position, relying on the action of the return spring 65, the positioning block 64 will automatically be clamped with the positioning groove 62 at the new position, thus completing the precise positioning of the test seat 2 at the new position. When the L-shaped clamping block 42 is inserted into the clamping groove 43, through the elastic force of the spring 44, the L-shaped clamping block 42 is tightly fixed in the clamping groove 43, thereby fixing the test seat 2. When it is necessary to replace the test seat 2, by pressing the L-shaped clamping block 42 to separate it from the clamping groove 43, the test seat 2 can be taken out for replacement or maintenance.
