Detailed Implementation

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0026] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0027] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention, which provides a high current-carrying energy meter. This device includes a meter body assembly 100. The meter assembly 100 includes a base 101, a connector 102 slidably inserted into the inner wall of the base 101, an energy meter body 103 snapped into the side wall of the base 101, a terminal block 104 adapted to be installed on the side wall of the energy meter body 103, and a connecting rod 105 inserted into the middle of the through hole in the side wall of the connector 102. The end of the connecting rod 105 is threadedly connected to the side wall of the energy meter body 103, and the energy meter body 103 slides in contact with the side wall of the base 101.

[0028] Furthermore, an adjusting rod 106 is rotatably mounted on the side wall of the base 101. The end of the adjusting rod 106 is threadedly connected to the end of the connector 102. Connecting rods 105 are symmetrically arranged on the side wall of the connector 102, and the end of the connecting rod 105 is threadedly connected to an adjusting nut that cooperates with the main body 103 of the electricity meter.

[0029] The meter body assembly 100 provides an installation reference and position fine-tuning function for the main body 103 of the electricity meter, ensuring accurate connection between the metering core and the external circuit. The base 101 provides rigid support for the overall equipment. The connector 102 (which can slide horizontally along the base 101) that slides into the inner wall of the base 101 is used to support the main body 103 of the electricity meter. The main body 103 of the electricity meter (with built-in metering chip and current transformer) is snapped into the side wall of the base 101. Initial positioning is achieved through sliding contact with the base 101. The end of the connecting rod 105 (high-strength bolt) in the through hole of the side wall of the connector 102 is threaded to the side wall of the main body 103 of the electricity meter. After tightening, the relative position of the main body of the electricity meter and the connector can be fixed. The end of the adjusting rod 106 (threaded rod) on the side wall of the base 101 is threaded to the connector 102. Rotating the adjusting rod 106 can push the connector 102 to slide along the base 101, thereby fine-tuning the horizontal position of the main body 103 of the electricity meter and ensuring that the terminal 104 is aligned with the external circuit. The adjusting nut at the end of the connecting rod 105 can further tighten the main body of the energy meter to prevent displacement caused by vibration.

[0030] When in use, depending on the position of the external line (such as the copper busbar in the distribution cabinet), rotate the adjusting rod 106 to push the connector 102 to slide along the base 101, thereby moving the main body 103 of the energy meter horizontally so that the terminal 104 is roughly aligned with the support seat 201 of the connecting component 200; tighten the adjusting nut at the end of the connecting rod 105 to fix the position of the main body 103 of the energy meter.

[0031] Example 2 Reference Figure 4 , Figure 6 and Figure 7 This is a second embodiment of the present invention, which differs from the first embodiment in that it provides a connection component 200 for a high current-carrying energy meter. The connection assembly 200 includes a support 201 snapped onto the side wall of the terminal 104, a conduit 202 inserted into the end of the terminal 104, a sliding seat 203 slidably connected to the side wall of the support 201, a fixing block 204 fixedly connected to the end of the sliding seat 203, and a clamping block 205 slidably connected to the side wall of the sliding seat 203. The clamping block 205 cooperates with the fixing block 204, and the end of the conduit 202 extends to one side of the fixing block 204.

[0032] The connecting component 200 serves as the connection hub between the energy meter and external high-current-carrying lines (such as busbars and cables). It achieves low-impedance docking through rigid clamping and automated advancement. The support seat 201 (insulated with phenolic resin to prevent short circuits), snapped onto the side wall of the terminal 104, provides an installation track for the sliding seat 203. The conduit 202, inserted into the end of the terminal 104, guides the external conductor (or copper busbar) into the docking area, while reducing the impact of conductor movement on the interface. The clamping blocks 205 on the side wall of the sliding seat 203 (symmetrically distributed with the fixing blocks, both made of high-conductivity materials such as copper) can slide along the sliding seat, cooperating with the fixing blocks 204 to clamp the external conductor.

[0033] Specifically, a drive shaft 206 is rotatably mounted on the side wall of the support base 201, a push gear 207 is fixedly connected to the end of the drive shaft 206, a rack plate 208 is fixedly connected to the bottom of the sliding seat 203, the teeth on the side wall of the push gear 207 mesh with the side wall of the rack plate 208, a push motor 209 is fixedly connected to the side wall of the support base 201, and the output end of the push motor 209 is connected to the end of the drive shaft 206 through a commutator.

[0034] The propulsion motor 209 on the side wall of the support base 201 drives the drive shaft 206 to rotate through the commutator. The propulsion gear 207 at the end of the drive shaft meshes with the rack plate 208 at the bottom of the sliding seat 203 to form a "motor-gear-rack" transmission chain. When the propulsion motor 209 rotates forward and backward, it can cooperate with the transmission components to drive the sliding seat 203 to move horizontally along the track of the support base 201, thereby driving the fixed block 204 at the end to move closer to or away from the adapter 300.

[0035] Furthermore, an eccentric block 210 is rotatably mounted on the side wall of the sliding seat 203. The end of the eccentric block 210 is in rotatable contact with the side wall of the clamping block 205, and a handle 211 is threadedly connected to the side wall of the eccentric block 210.

[0036] The eccentric block 210 (cam structure) rotatably mounted on the side wall of the sliding seat contacts the side wall of the clamping block. Rotating the handle 211 causes the eccentric block to rotate, which pushes the clamping block 205 toward the fixed block 204, achieving rigid locking of the docking part, preventing the connecting parts from loosening, and ensuring low contact resistance under high current.

[0037] When in use, pass the external high current-carrying wire (or copper busbar) through the conduit 202 and place the end between the fixing block 204 and the clamping block 205; turn the handle 211 to rotate the eccentric block 210, push the clamping block closer to the fixing block, and rigidly clamp the wire (the contact pressure is controlled by the stroke of the eccentric block to ensure low impedance).

[0038] Start the propulsion motor 209, and through the transmission of the drive shaft 206, the propulsion gear 207 and the rack plate 208, drive the sliding seat 203 to move along the support seat 201 towards the main body of the energy meter, so that the female connector 305 (which is connected to the external wire) on the fixed block 204 is close to the male connector 304 inside the main body of the energy meter.

[0039] Example 3 Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a high current-carrying energy meter adapter assembly 300 and a terminal block 400 inserted into the side wall of the adapter assembly 300. The terminal block 400 is electrically connected to the energy meter body 103 via a wire. The end of the adapter assembly 300 is connected to the other side of the fixing block 204. One end of the terminal block 400 (copper columnar structure, gold-plated surface) is electrically connected to the metering circuit of the energy meter body 103 via a wire, and the other end is rotatably inserted into the center of the extension head 310. The angle can be finely adjusted with the extension head to ensure reliable conduction between the adapter assembly and the internal circuit of the energy meter body, while reducing the impact of mechanical stress on the metering element.

[0040] The adapter assembly 300 includes a pad 301 fixedly connected inside the main body 103 of the electricity meter, a turntable 302 rotatably mounted in the middle of the pad 301, a connector 303 fixedly connected to the side wall of the turntable 302, a male connector 304 rotatably mounted on the end side wall of the connector 303, and a female connector 305 snapped between the fixing block 204 and the clamping block 205. The end of the male connector 304 is provided with a thread that mates with the end of the female connector 305.

[0041] The adapter component 300 is an internal conductive bridge between the main body 103 of the electricity meter and the external circuit. It achieves high-precision docking through motor drive to ensure the stability of high current transmission. The turntable 302 (with toothed edges) is rotatably mounted on the pad 301 (insulating board, such as epoxy glass cloth board) inside the main body 103 of the electricity meter. It can rotate around the center of the pad 301. The male connector 304 is rotatably mounted on the connector seat 303 on the side wall of the turntable. It can rotate with the turntable 302 to achieve circumferential alignment.

[0042] Specifically, a steering motor 306 is fixedly connected to the side wall of the pad 301, and a steering gear 307 is fixedly connected to the end of the output shaft of the steering motor 306. The teeth on the side wall of the steering gear 307 mesh with the rack on the side wall of the turntable 302.

[0043] Among them, the steering motor 306 on the side wall of the pad 301 drives the steering gear 307 to rotate, and the gear meshes with the turntable rack, driving the turntable 302 to rotate.

[0044] Furthermore, the adapter assembly 300 also includes a fixed base 308 fixedly connected to the side wall of the pad 301, an adapter 309 rotatably mounted at the center of the fixed base 308, and an extension head 310 connected to the center of the adapter 309. The terminal block 400 is rotatably inserted into the center of the extension head 310. The extension head 310 is electrically connected to the male connector 304 via a wire. A main connecting rod 311 is fixedly connected to the side wall of the adapter 309. A secondary connecting rod 312 is hinged to the end of the main connecting rod 311. The end of the secondary connecting rod 312 is fixedly connected to the side wall of the male connector 304. The main connecting rod 311 and the secondary connecting rod 312 are symmetrically arranged. A drive motor 313 is fixedly connected to the side wall of the fixed base 308. The side wall of the drive motor 313 is connected to the side wall of the adapter 309 via a commutator.

[0045] In this design, on the fixed base 308 on the side wall of the pad 301, an adapter 309 (conductive hub) is rotatably mounted and connected to an extension head 310 (a flexible conductor, such as multi-strand copper wire with an outer insulating layer). A terminal block 400 (a conductive post connected to the internal circuit of the energy meter body) is rotatably inserted into the center of the extension head 310, forming a conductive path of "energy meter body - terminal block - extension head - adapter". The main connecting rod 311 on the side wall of the adapter 309 is hinged to the secondary connecting rod 312 on the side wall of the connector male head 304 (two sets are symmetrically distributed). When the drive motor 313 on the side wall of the fixed base 308 drives the adapter to rotate through the commutator, the main connecting rod 311 pulls the secondary connecting rod 312, causing the connector male head 304 to rotate, making it easy to screw into the end of the connector female head 305 to achieve circuit connection, and also easy to actively disconnect the circuit for protection.

[0046] Preferably, a limiting post 314 is fixedly connected to the side wall of the pad 301, and a pointer 315 is fixedly connected to the side wall of the turntable 302. The end of the pointer 315 extends to the side wall of the limiting post 314, and the limiting posts 314 are symmetrically arranged on the side wall of the turntable 302.

[0047] Among them, the limiting posts 314 (symmetrically distributed) on the side wall of the pad 301 are used to limit the rotation angle of the turntable 302 (to avoid excessive rotation and wire entanglement). The end of the pointer 315 on the side wall of the turntable extends to the side wall of the limiting post 314. The rotation angle of the turntable 302 can be determined by the position of the pointer 315 to assist in alignment and calibration.

[0048] When in use, the steering motor 306 is started, driving the steering gear 307 to rotate the turntable 302, so that the circumferential angle of the male connector 304 is aligned with the female connector 305 (the rotation range is limited by the cooperation of the pointer 315 and the limit post 314 to avoid overtravel).

[0049] The drive motor 313 starts, driving the adapter 309 to rotate via the commutator. The main connecting rod 311 pulls the secondary connecting rod 312, pushing the male connector 304 to rotate axially and move towards the female connector 305 along with the turntable 302. When the two contact, they are tightened using the threaded structure at the ends (or through axial pressure to achieve tight contact), forming a conductive path of "external wire - female connector - male connector - extension head - adapter - terminal block - electricity meter body". Current flows into the electricity meter body 103 through the above conductive path. The built-in metering chip and current transformer sample and calculate the high current carrying capacity to achieve accurate metering.

[0050] In summary, the coordinated control of the steering motor and drive motor enables automated alignment of the connector in both the circumferential and axial directions. Combined with manual fine-tuning of the adjusting rod, installation time is short. The eccentric block locking mechanism requires no specialized tools, allowing a single person to secure the wiring. The base, support, and other metal components feature a rigid design, and the double locking mechanism of the connecting rod and adjusting nut ensures stable connection. The docking structure can be quickly separated via motor drive, allowing for external wiring replacement or internal component maintenance without disassembling the main body of the energy meter. The cooperation between the limit post and the pointer prevents overtravel during automated operation, reducing maintenance risks and making it suitable for continuous production scenarios. The design of the adjusting rod and sliding seat can accommodate external wiring of different specifications. The flexible connection of the terminals allows for slight angular deviations between the energy meter body and the adapter assembly, compatibility with installation errors in older distribution cabinets. During operation, the rigid mechanical structure ensures stable contact pressure, and the low-impedance design reduces power loss and heat generation. For maintenance, simply reverse the operation of the propulsion and drive motors to separate the docking structure without disassembling the entire device.

[0051] Example 4 This is a fourth embodiment of the present invention, which differs from the third embodiment in that it provides a method for using a high current-carrying energy meter, including the following steps: Step 1: Preparation before installation: Inspect all components of the equipment, and confirm that the base, connectors, and main body of the meter assembly, as well as the support, conduit, and sliding seat of the connecting components, are intact and free from damage or deformation; check whether the gold plating layer on the surface of the wiring terminals is intact and whether the silver plating layer of the male connector is worn. Choose an installation location: It should be well-ventilated, away from heat sources and strong electromagnetic interference, and the installation surface should be flat to accommodate the rigid support requirements of the metal base. Prepare tools: prepare wrenches, infrared thermometers, and copper terminal blocks that meet specifications; Step Two: Meter Positioning and Calibration: Based on the location of the external wiring (such as the copper busbar in the distribution cabinet), rotate the adjusting rod to push the connector to slide along the base, causing the main body of the energy meter to move horizontally, so that the terminals and the support of the connecting components are roughly aligned, and the adjustment accuracy is controlled within the set range; tighten the adjusting nut at the end of the connecting rod to fix the relative position of the main body of the energy meter and the connector to prevent displacement caused by vibration; check the relative position of the pointer on the side wall of the turntable and the limit post on the side wall of the pad to ensure that the turntable is at the initial angle, that is, the male connector is facing the mating direction, to prepare for subsequent automated docking; Step 3: External line fixing and connection drive: Pass the external high current-carrying wire (or copper busbar) through the conduit, and place the end between the fixing block and the clamping block to ensure that the wire specifications are compatible; Rotate the handle to make the eccentric block rotate, push the clamping block closer to the fixed block, and rigidly clamp the wire to ensure contact pressure; start the propulsion motor, and through the transmission of the drive shaft, propulsion gear and rack plate, drive the sliding seat to move along the support seat towards the main body of the energy meter, so that the female connector on the fixed block is close to the male connector inside the main body of the energy meter. Step 4: Internal Adapter Automated Alignment and Locking: Start the steering motor, drive the steering gear to rotate the turntable, aligning the circumferential angle of the male connector with the female connector. Use the pointer and limit post to judge the alignment, avoiding excessive rotation that could cause wire tangling. Start the drive motor, drive the adapter to rotate through the commutator, the main connecting rod pulls the secondary connecting rod, and moves the male connector axially toward the female connector. When they contact each other, tighten using the threaded structure at the ends (or achieve tight contact through axial pressure), forming a complete conductive path. Step 5: Operation Monitoring and Maintenance Operation monitoring: After the current flows into the main body of the energy meter through the conductive path, the built-in metering chip and current transformer sample and calculate the high current carrying capacity. Real-time current, voltage, power and cumulative energy consumption can be viewed through the panel buttons or the supporting management software to ensure metering accuracy. Routine maintenance: Check the temperature rise at the wiring points monthly with an infrared thermometer to ensure the temperature is within the normal operating range; clean the surface dust quarterly after disconnecting the power. Troubleshooting: If problems such as poor contact occur, reverse the operation of the push motor and drive motor to separate the docking structure. Repair can be performed without disassembling the entire equipment. After repair, repeat the docking operation as described above. Regular calibration: Annual metrological calibration is performed by a professional organization, using a standard source to input a simulated high-current signal to ensure metrological accuracy.
