Description

Technical Field

[0001] The utility model relates to the technical field of analog power supplies, and more specifically, to a capacitance detection device for an analog power supply. Background Technique

[0002] An analog power supply is a power supply system that mainly outputs analog signals (continuously varying voltages or currents) to provide electrical energy for circuits or devices. Compared with digital power supplies, the output of an analog power supply does not exist in the form of discrete digital pulses, but is a continuously adjustable voltage or current. This continuous power output makes analog power supplies particularly important in applications that require precise control of voltage and current.

[0003] With the rapid development of electronic technology, analog power supplies are increasingly widely used in various electronic devices, and their stability and reliability directly affect the overall performance of the devices. As an indispensable and important component in an analog power supply, the performance of a capacitor directly affects the filtering effect of the power supply, voltage stability, and the overall safety of the circuit. However, in actual applications, the performance of capacitors may change due to minor differences in the production process, long-term effects of environmental factors (such as temperature and humidity), and aging during use, thereby affecting the working quality of the power supply. Traditional capacitor detection methods mainly rely on manual testing. During the detection process, an analog power supply is mainly held by hand for detection. Handheld operation is easily affected by factors such as the stability of the operator's hand and force control, resulting in unstable contact during the test and thus affecting the accuracy of the measurement results.

[0027] Please refer to Figures 1-5, the present utility model provides a technical solution:

[0030] A discharge component, which is located on the outer surface of the other side of the support frame 1 and is used to discharge the analog power supply body 2, so that manual operation is not required, and the analog power supply body 2 is placed on the backing plate 16.

[0031] Further, the adjustable support component includes a first rack 8, a second rack 9, a gear 10 and a first movable groove 14. The gear 10 is rotatably connected to the outer surface of the support frame 1, the outer surface of the gear 10 is meshed with the first rack 8 and the second rack 9. The first rack 8 and the second rack 9 are located on both sides of the gear 10 and are slidably connected to the outer surface of the support frame 1. The second rack 9 is located above the first rack 8. First movable grooves 14 are respectively provided on the outer surfaces of the clamping plates 3, and second movable grooves 17 are provided on the outer surfaces of the two clamping plates 3. The second movable grooves 17 are located above the first movable grooves 14, and drive the second rack 9 fixedly connected thereto to move synchronously. During the movement of the second rack 9, the gear 10 is driven to rotate. While the gear 10 is rotating, the first rack 8 is driven to move synchronously towards the center of the support frame 1, so that the clamping plates 3 slide along the outer surface of the support frame 1. At the same time, the first rack 8 and the second rack 9 respectively move in the first movable groove 14 and the second movable groove 17, and the two clamping plates 3 gradually approach the analog power supply body 2.

[0032] Further, the first rack 8 is movably connected to the first movable groove 14 corresponding to the clamping plate 3, the first rack 8 is fixedly connected to the inside of the other clamping plate 3, the second rack 9 is movably connected to the second movable groove 17 corresponding to the clamping plate 3, the second rack 9 is fixedly connected to the other clamping plate 3, and at the same time, the first rack 8 and the second rack 9 respectively move in the first movable groove 14 and the second movable groove 17.

[0033] Further, a screw rod 4 is rotatably connected to the outer surface of the support frame 1, and the end of the screw rod 4 is fixedly connected to the adjacent clamping plate 3. Rotating the screw rod 4 causes the screw rod 4 to push the adjacent clamping plate 3 towards the center of the support frame 1.

[0034] Furthermore, a multimeter 6 is fixedly installed at the top of the support frame 1. Two connecting wires 7 are electrically connected to the outer surface of the multimeter 6. The other ends of the two connecting wires 7 are both fixedly installed with probe tips 15. The two connecting wires 7 are used to connect the multimeter 6 and the probe tips 15.

[0035] Furthermore, fixed blocks 5 are fixedly connected to the outer surfaces of the two clamping plates 3. The two connecting wires 7 are both located within the corresponding fixed blocks 5 and the two probe tips 15 are both located outside the connecting wires 7. The two probe tips 15 are movably connected to the outer surface of the analog power supply body 2, and at the same time drive the probe tips 15 located on the two fixed blocks 5 to contact the outer surface of the analog power supply body 2 (i.e., the positive and negative electrodes of the capacitor).

[0036] Furthermore, the discharging assembly includes an electric telescopic rod 11, an insulating block 12 and a conductive block 13. The electric telescopic rod 11 is fixedly installed at the top of the other side of the support frame 1. The end of the electric telescopic rod 11 is fixedly connected to the insulating block 12. The bottom of the insulating block 12 is fixedly connected to the conductive block 13. The conductive block 13 is movably connected to the outer surface of the analog power supply body 2. Start the electric telescopic rod 11 in the discharging assembly. The extension of the electric telescopic rod 11 drives the insulating block 12 and the conductive block 13 to move towards the analog power supply body 2. When the conductive block 13 contacts the outer surface of the analog power supply body 2, since the conductive block 13 is connected to the electric telescopic rod 11 through the insulating block 12, the safety of the discharging process is ensured, and the capacitor inside the analog power supply body 2 starts to discharge through the conductive block 13.

[0037] Working principle: When the staff needs to use the capacitance detection device of the simulated power supply, when the device is not started, the adjustable support assembly is in the initial position, that is, the first rack 8 and the second rack 9 are respectively located on both sides of the gear 10, and the two clamping plates 3 maintain a certain distance from the gear 10 through their respective connected racks. The simulated power supply body 2 is placed on the pad 16, but has not been firmly clamped. Before the capacitance detection, it is necessary to ensure that the capacitor inside the simulated power supply body 2 has been completely discharged to avoid safety hazards during the detection process. At this time, the discharge component enters the working state, and the user starts the electric telescopic rod 11 in the discharge component. The extension of the electric telescopic rod 11 drives the insulating block 12 and the conductive block 13 to move toward the simulated power source body 2. When the conductive block 13 contacts the outer surface of the simulated power source body 2, since the conductive block 13 is connected to the electric telescopic rod 11 through the insulating block 12, the safety of the discharge process is ensured. The capacitor inside the simulated power source body 2 begins to discharge through the conductive block 13. After the discharge process continues for a certain period of time, the capacitive charge inside the simulated power source body 2 is gradually released. The user can stop the extension of the electric telescopic rod 11 as needed, or set an automatic stop mechanism to automatically disconnect the conductive block after detecting that the current drops to a safe range. The conductive block 13 is only in contact with the simulated power source body 2 without generating any force, so that the simulated power source body 2 can be stably placed on the pad 16. After discharging, the user rotates the screw 4 so that the screw 4 pushes the adjacent clamping plate 3 to move toward the center of the support frame 1, thereby driving the second rack 9 fixedly connected thereto to move synchronously. The second rack 9 drives the gear 10 to rotate during the movement, and the gear 10 drives the first rack 8 to move synchronously toward the center of the support frame 1 while rotating, thereby causing the clamping plate 3 to slide along the outer surface of the support frame 1, and at the same time, the first rack 8 and the second rack 9 are respectively on the first rack 9. The two clamping plates 3 gradually approach the simulated power supply body 2, and the position of the simulated power supply body 2 is precisely fixed, which provides stability for subsequent capacitance detection. When the two clamping plates 3 contact the simulated power supply body 2, the probes 15 located on the two fixed blocks 5 are simultaneously driven to contact the outer surface of the simulated power supply body 2 (i.e., the positive and negative poles of the capacitor), and the multimeter 6 is started. After selecting the appropriate capacitance detection mode, the multimeter 6 will send a test signal to the simulated power supply body 2 and measure the response of the capacitor, such as capacity, leakage current, equivalent series resistance (ESR) and other key parameters. The measurement results will be directly displayed on the display screen of the multimeter 6 for the user to analyze and judge the performance status of the capacitor. The two connecting wires 7 are used to connect the multimeter 6 and the probes 15.
