[0036] Output terminal 8: Connected to one side of the outer end of the current box 2. The current processed inside the current box 2 is output from here, forming a complete current path together with the input terminal 7, which meets the experimental requirements for the current transmission path.
[0037] Rotary motor 9: Installed on both sides of the outer end of the base 1, its output shaft is connected to screw 17. After starting, the output shaft of rotary motor 9 drives screw 17 to rotate, providing power for the movement of slider 18, thereby realizing the fixing operation of clamping block 19 on current box 2, ensuring that current box 2 remains stable during the experiment.
[0038] Connection line 10: Inside the current box 2, it connects the current transmission path from the input terminal 7 to the output terminal 8. At the same time, a current sensor 11 is connected to its front end, which is responsible for transmitting the current to the current sensor 11 for real-time monitoring, ensuring the normal transmission and monitoring of the current throughout the experiment.
[0039] Current sensor 11: Connected to the front end of the connecting line 10, its function is to monitor the magnitude of the current in real time and transmit the collected current data to the PLC controller 15 to provide current data support for subsequent experimental analysis and control.
[0040] Voltage sensor 12: Connected to the back end of current sensor 11, it is mainly responsible for monitoring the voltage magnitude and transmitting the collected voltage data to PLC controller 15.

[0045] Screw 17: It is set in the grooves opened on both sides of the upper surface of the base 1, and one end is connected to the output end of the rotary motor 9. When the rotary motor 9 is started, it drives screw 17 to rotate, and uses the principle of thread transmission to drive slider 18, which is threaded and sleeved on its outer end, to make linear motion in the groove.
[0046] Slider 18: Threaded onto the outer end of screw 17, located in the grooves on both sides of the upper surface of base 1. Its upper end extends to the upper outer end of base 1 and connects to the lower surface of clamping block 19. When screw 17 rotates, slider 18 moves accordingly, thereby driving clamping block 19 to move, thus achieving the fixing operation of current box 2.
[0047] Clamping block 19: It is set around the upper surface of the base 1, and its lower surface is connected to the slider 18. When the slider 18 moves, the clamping block 19 moves accordingly, so that the inner side of the clamping block 19 is in contact with the lower four corner surfaces of the current box 2, which firmly fixes the current box 2 on the base 1 and prevents the current box 2 from being displaced during the experiment.
[0048] Guide plate 20: Located in the center inside the bracket 3, with a screw 21 connected to the center of its upper surface and sliders 23 connected to its outer two sides. When the rotating knob 22 drives the screw 21 to rotate, the guide plate 20 moves up and down along the guide groove inside the bracket 3 because the screw 21 engages with the threaded hole on the bracket 3. The sliders 23 slide within the guide groove, providing guidance and stability. A mounting plate 25 is provided on the front surface of the guide plate 20 for mounting and connecting the probe 27 and related components.
[0049] Screw 21: Connected to the center of the upper surface of the guide plate 20, its upper end extends to the outer upper end of the bracket 3 through a threaded hole and is fitted with a knob 22. When the knob 22 is rotated, screw 21 rotates accordingly, and through its engagement with the threaded hole of the bracket 3, the guide plate 20 moves up and down along the inner guide groove of the bracket 3, thereby adjusting the height position of the connecting probe 27.
[0050] Button 22: Installed on the upper end of screw 21, located at the upper outer end of bracket 3. By rotating button 22, the operator drives screw 21 to rotate, thereby adjusting the position of guide plate 20. The operation is convenient and facilitates precise control of the docking height between connection probe 27 and the rear connection end of current box 2.
[0051] Slider 23: Connected to the outer two surfaces of the guide plate 20, with its outer ends slidingly fitted into guide grooves opened on opposite inner surfaces of the bracket 3. When the guide plate 20 moves up and down along the guide grooves on the inner side of the bracket 3, slider 23 guides and stabilizes the movement of the guide plate 20, ensuring smooth movement of the guide plate 20 and guaranteeing the accuracy of the docking operation of the connecting probe 27.
[0052] Bolt 24: Connected to both sides of the rear end surface of the mounting plate 25, with the other end extending to the outer rear end of the guide plate 20 through a threaded hole. By rotating the bolt 24, the position of the mounting plate 25 on the guide plate 20 can be adjusted, thereby achieving a preliminary adjustment of the horizontal position of the connecting probe 27 to meet the requirement of precise docking with the rear end of the current box 2.
[0053] Mounting plate 25: Located on the front surface of guide plate 20, and connected to guide plate 20 on both sides of the rear surface by bolts 24. A limiting groove is formed on its front surface for mounting slider 26 and connecting probe 27, making it an important component for the installation and position adjustment of connecting probe 27.
[0054] Slider 3 26: It slides into the limiting groove opened on the front surface of the mounting plate 25, and several connecting probes 27 are arranged on its front surface. By sliding in the limiting groove, slider 3 26 can make fine adjustments to the position of the connecting probes 27, ensuring that the outer front end of the connecting probe 27 can be accurately inserted into the connecting end opened at the rear end of the current box 2, thus establishing a stable and reliable electrical connection.
[0055] Connection probe 27: Arranged on the front surface of slider 3 26, its front outer end is used to insert into the connection end opened at the rear end of the current box 2 to establish an electrical connection, providing a channel for subsequent data transmission and control, and is a key component for realizing the connection between the current box 2 and the external control and monitoring system.
[0056] Place the current box 2 in the center of the upper surface of the base 1. Start the rotary motors 9 on both sides of the outer end of the base 1. The output of the rotary motors 9 drives the connected screw 17 to rotate. Since the slider 18 is threaded onto the screw 17, the rotation of the screw 17 will cause the slider 18 to move linearly along the groove. The upper end of the slider 18 is connected to the clamping block 19, so the movement of the slider 18 will drive the clamping block 19 to move until the inner side of the clamping block 19 is in contact with the lower four corner surfaces of the current box 2, thus firmly fixing the current box 2 on the base 1 and preventing displacement of the current box during the experiment from affecting the experimental results. By rotating the knob 22 at the upper end of the bracket 3, the screw 21 is driven to rotate. Because the screw 21 is connected to the upper end of the bracket 3... The threaded hole fits, so the rotation of screw 21 causes guide plate 20 to move up and down along the guide groove on the inner side of bracket 3. Slider 23 on both sides of the outer end of guide plate 20 slides in the guide groove, which guides and stabilizes the movement of guide plate 20, ensuring smooth movement of guide plate 20. By rotating bolt 24 at the rear end of mounting plate 25, the position of mounting plate 25 on guide plate 20 can be adjusted. At the same time, slider 26 in the limiting groove at the front end of mounting plate 25 can drive connecting probe 27 to slide in the limiting groove, realizing fine adjustment of the position of connecting probe 27. Finally, the outer end of connecting probe 27 is accurately inserted into the connecting end opened at the rear end of current box 2, establishing an electrical connection and providing a channel for subsequent data transmission and control. External current passes through the front end of current box 2. The current enters through the lower end of the terminal 7, is transmitted via the connecting line 10, and finally outputs from the output terminal 8, forming a complete current path to provide the required current for the experiment. During the current transmission process, the current sensor 11 monitors the current magnitude in real time and transmits the collected current data to the PLC controller 15. The voltage sensor 12 simultaneously monitors the voltage magnitude and also transmits the collected voltage data to the PLC controller 15. This data forms the basis for subsequent experimental analysis and control. The protector 13 constantly monitors the circuit's operation. When an abnormality in current or voltage, such as overcurrent or overvoltage, is detected, the protector 13 will quickly activate, cutting off the circuit or taking other protective measures to prevent equipment damage due to abnormal conditions. The filter 14 filters the current... The current is filtered to remove interference signals, ensuring its stability and purity, thereby improving the accuracy of experimental data. The PLC controller 15, as the core of the entire device, receives data from the current sensor 11 and voltage sensor 12, and analyzes and processes it. Simultaneously, the wireless transceiver module 16 connected to the PLC controller 15 enables data communication with external devices. Operators can remotely monitor experimental data through external devices and send control commands to the PLC controller 15 to remotely control the experimental process. Before the experiment begins, the operator sets the required experimental data on the control panel 4. The PLC controller 15 compares and analyzes the collected current and voltage data, and based on the comparison results…The PLC controller 15 automatically adjusts relevant data in the circuit to track and adjust the current in real time, keeping it within a preset range to control the temperature rise current. If the collected current value is lower than the preset value, the PLC controller 15 increases the power output to increase the current; conversely, it decreases the output power. The current box 2 generates heat during operation. To prevent excessive temperature from affecting equipment performance and experimental results, several heat dissipation slots 5 arranged on the upper surface of the current box 2 dissipate heat to the surrounding environment, ensuring the current box 2 operates at a suitable temperature. When the current box 2 malfunctions, such as excessive temperature, current or voltage exceeding safe limits, the alarm light 6 will emit an alarm signal to remind the operator to handle the situation promptly and avoid unexpected experimental situations.
