DETAILED DESCRIPTION
[0025] In order to make the above-mentioned purposes, features and advantages of the application more obvious and easy to understand, the specific embodiments of the application will be described in detail below with reference to the accompanying drawings.
[0026] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the application, but the application can also be implemented in other ways different from the description, and those skilled in the art can make similar generalizations without departing from the connotation of the application, so the application is not limited by the specific embodiments disclosed below.
[0027] Secondly, "one embodiment" or "embodiment" referred to herein means that a specific feature, structure or characteristic can be included in at least one implementation of the application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.
[0028] Thirdly, the application is described in detail in conjunction with the schematic view, and in the detailed description of the embodiments of the application, the cross-sectional view of the device structure will be partially enlarged without the general proportion for the convenience of description, and the schematic view is only an example, which should not limit the scope of protection of the application here. In addition, three-dimensional spatial dimensions including length, width and depth should be included in actual manufacture.
[0029] Embodiment 1 Reference Figures 1-7 For the first embodiment of the present application, a metering assembly 100 of an electric energy meter with split electrical connection is provided, The metering assembly 100 includes a housing 101, an electric energy meter body 102 encapsulated inside the housing 101, a cover plate 103 plugged into the side wall of the housing 101, and a sealing plate 104 fixedly connected to the side wall of the housing 101, the sealing plate 104 being clamped to the outside of the electric energy meter body 102, and the cover plate 103 being clamped to the outside of the wiring area of the electric energy meter body 102.
[0030] The metering assembly 100 is the basic carrier of electric energy metering, and realizes quick access and locking of external lines through a special incoming line connection structure, ensuring metering safety and convenient operation and maintenance. The housing 101 is made of flame-retardant ABS material, providing an installation frame and protective shell for the overall device. The side wall is provided with clamping grooves for the cover plate and the sealing plate, and the inner wall is provided with limiting blocks and fixed bosses for the connection assembly, ensuring the installation precision of each component. The electric energy meter body 102 is encapsulated inside the housing, including a current / voltage sampling module (precision 0.2 level, complying with GB / T17215.323-2022), a data processing unit (ARM Cortex-M3 core, supporting remote meter reading), and a wiring terminal area, which is the core of electric energy metering. Its outside is clamped and protected by the sealing plate 104 (insulating PC material) to prevent dust from entering; the cover plate 103 (transparent acrylic material) is clamped to the outside of the wiring area, allowing direct observation of the wiring state, and the cover plate is designed with a snap-on type for quick opening and closing (without tools).
[0031] Specifically, the metering assembly 100 further includes a limiting block 105 fixedly connected to the inside of the incoming line port of the side wall of the housing 101, a connector female head 106 fixedly connected to the middle of the limiting block 105, and a connector male head 107 slidingly plugged into the side wall of the limiting block 105, the end of the connector male head 107 being plugged into the center of the connector female head 106.
[0032] The limiting block 105 is fixed to the inside of the incoming line port of the side wall of the housing 101 (metal material, corrosion-resistant treatment), the connector female head 106 (copper conductive terminal) is integrated inside, and the external line is plugged and connected through the connector male head 107 (matching the female head, with a positioning pin), realizing "tool-free quick wiring".
[0033] Furthermore, a locking block 108 is hinged inside the limiting block 105. The end of the locking block 108 is locked to the side wall of the male connector 107. The locking blocks 108 are symmetrically arranged inside the grooves on the side wall of the female connector 106. A spring 109 is fixedly connected to the side wall of the limiting block 105. The end of the spring 109 is fixedly connected to the side wall of the locking block 108. A push block 110 is slidably connected to the side wall of the limiting block 105. The end of the push block 110 is locked to the outside of the end of the locking block 108. A slot is opened on the inner side of the end of the push block 110 to cooperate with the end of the locking block 108. An elbow clamp 111 is fixedly connected to the side wall of the limiting block 105. The output shaft end of the elbow clamp 111 is fixedly connected to the side wall of the push block 110.
[0034] The limiting block 105 has two sets of locking blocks 108 (made of nylon and with anti-slip teeth) symmetrically hinged inside. Under normal conditions, under the pushing force of the spring 109 (compression spring), the end of the locking block 108 is locked in the groove on the side wall of the male connector 107 to prevent the male connector from loosening. The side wall of the limiting block is slidably connected to the push block 110 (with a slot that cooperates with the locking block). The outside of the push block is connected to the elbow clamp 111 (manual quick clamp). Pressing the elbow clamp 111 can push the push block 110 to squeeze the locking block 108, overcome the pushing force of the spring 109 to unlock, and realize the quick pull-out of the male connector.
[0035] In use, the elbow clamp 111 on the side wall of the connector housing 101 is pressed to unlock the connector. The output shaft of the elbow clamp pushes the push block 110 to slide along the limit block 105. The push block slot squeezes the locking block 108, overcoming the thrust of the spring 109 and causing the locking block to disengage from the groove of the connector male head 107, thus unlocking the connector. For male and female head connection, the insulation layer of the external power line (live wire and neutral wire) is stripped, inserted into the wiring hole of the connector male head 107, and the fixing bolt is tightened. Then, the male head is aligned with the connector female head 106 in the limit block and inserted axially until a "click" sound is heard (the locking block resets and locks the male head under the action of the spring), completing the mechanical and electrical connection of the incoming line. The main body 102 of the electricity meter collects the incoming current and voltage signals through the current / voltage sampling module. The data processing unit calculates parameters such as power and electricity consumption, displays them in real time, and uploads them to the remote meter reading system. The metering accuracy meets the 0.2 level standard. To disconnect the external wiring, press the elbow clamp 111 to unlock the connector and pull out the male end. No wire disconnection is required. After maintenance, repeat the "incoming line connection - split electrical connection" steps to restore operation.
[0036] In summary, the male and female connectors plus the elbow clamp unlocking structure enable tool-free and quick access to external lines, avoiding the risk of stripping threads associated with traditional bolt wiring; the anti-disengagement design of the locking block and spring provides high tensile strength, preventing lines from loosening due to external pulling; the insulation design of the limit block and connector ensures a long creepage distance, meeting safety standards and preventing electric shock or short circuit accidents.
[0037] Example 2 Reference Figures 1-7This is the second embodiment of the present invention, which differs from the first embodiment in that it provides a connection component 200 for an energy meter with a split electrical connection.
[0038] The connecting assembly 200 includes a cover plate 201 fixedly connected inside the housing 101, a main moving plate 202 slidably connected to the side wall of the cover plate 201, a guide plate 203 fixedly connected to the middle position inside the cover plate 201, a support plate 204 slidably connected to the side wall of the guide plate 203, and a secondary moving plate 205 fixedly connected to the end of the support plate 204. A wiring connector 206 is fixedly connected to the end of the main moving plate 202. The secondary moving plate 205 works in conjunction with the main moving plate 202. A wiring connector 206 of the same specification is installed on the upper end of the secondary moving plate 205. The secondary moving plate 205 is slidably disposed inside the cover plate 201.
[0039] Among them, the connecting component 200 is the core of realizing "split electrical connection". Through synchronous transmission and precise guidance, the driving wiring connector enables the detachable docking of the main body of the energy meter and the external line. The cover plate 201 is fixed inside the housing 101 (metal bracket with dustproof flange) to provide installation and protection space for moving parts. The guide plate 203 is fixed in the middle of the inside of the cover plate and has a concave arc groove (adapted to the movement trajectory of the auxiliary moving plate). The support plate 204 (metal slider with lubricating coating) slides in the arc groove to limit the movement direction of the auxiliary moving plate 205 and ensure that there is no offset when the wiring connector is docked. The wiring connector 206 is fixed at the ends of the main and auxiliary moving plates to realize the conductive connection between the main body of the energy meter 102 and the external line.
[0040] Specifically, the connecting assembly 200 also includes a main slide rail 207 fixedly connected to the top side wall of the cover plate 201, a main slider 208 adapted to be installed on the side wall of the main slide rail 207, and a timing belt 209 rotatably installed on the inner wall of the cover plate 201 via a timing pulley. The end of the main moving plate 202 is bolted to the side wall of the main slider 208, and the upper side wall of the timing belt 209 is fixedly connected to the lower side wall of the main moving plate 202.
[0041] The main moving plate 202 (insulated PC board with reinforcing ribs) is fixed to the side wall of the main slider 208 (adapted to the main slide rail 207) by bolts at its end, and the lower side wall is fixedly connected to the upper end of the synchronous belt 209 (polyurethane material with steel wire core). The synchronous belt 209 is driven by the synchronous pulley (motor driven, or the main moving plate 202 can be moved by an electric push rod) on the inner wall of the cover plate 201. When the synchronous belt rotates clockwise, it drives the main moving plate to slide along the main slide rail toward the wiring area.
[0042] Furthermore, the connecting assembly 200 also includes a guide rod 210 fixedly connected to the side wall of the secondary moving plate 205, a nest 211 slidably connected to the side wall of the guide rod 210, and a push plate 212 fixedly connected to the side wall of the nest 211. The lower side wall of the synchronous belt 209 is fixedly connected to the side wall of the push plate 212. A through hole is opened in the middle of the push plate 212. The support plate 204 is inserted into the inner side of the through hole in the middle of the push plate 212. The push plate 212 is positioned above the guide plate 203. A pad 213 is fixedly connected to the inner side of the cover plate 201. A secondary guide rail 214 is fixedly connected to the end of the pad 213. A secondary slider 215 is adapted to be installed on the middle side wall of the secondary guide rail 214. The push plate 212 is bolted to the end of the secondary slider 215. An arc-shaped groove is opened in the middle of the guide plate 203. The arc-shaped groove in the middle of the guide plate 203 has a concave structure. The lowest point of the arc-shaped groove in the middle of the guide plate 203 is located at the center of the cover plate 201.
[0043] The auxiliary moving plate 205 (of the same specifications as the main moving plate) of the auxiliary moving plate drive unit has a fixed support plate 204 at its end and a fixed guide rod 210 (a metal rod that keeps the movement stable) on its side wall. A nest 211 is slidably sleeved on the outside of the guide rod, and a push plate 212 (a metal plate with a synchronous belt connection hole) is fixed on the side wall of the nest. The lower side wall of the synchronous belt 209 is fixedly connected to the push plate 212. When the synchronous belt rotates, the push plate slides along the auxiliary guide rail 214. Through the nest and the guide rod, the auxiliary moving plate is driven to slide along the arc groove of the guide plate, realizing the "reverse synchronous movement" of the main and auxiliary moving plates (when the main moving plate 202 approaches, the auxiliary moving plate 205 also approaches the wiring area synchronously).
[0044] It should be noted that the wiring connector 206 includes a base 206a fixedly connected to the end of the main moving plate 202, a frame 206b inserted into the end of the base 206a, an insulating post 206c fixedly connected to the inner wall of the frame 206b, an electrode 206d fixedly connected to the end of the insulating post 206c, and a wiring terminal 206e fixedly connected to the end of the electrode 206d. A set of wiring terminals 206e is electrically connected to the main body 102 of the energy meter via wires. A knob 206f is inserted into the side wall of the base 206a. The end of the knob 206f is threaded to the bottom of the frame 206b. The side wall of the frame 206b has fins, and the fins of the side wall of the frame 206b have arc-shaped edges. The side wall of the base 206a has slots that cooperate with the fins of the side wall of the frame 206b.
[0045] The base 206a is fixed to the end of the movable plate (metal material with grounding terminal), and the side wall is provided with a slot that matches the fins of the frame 206b to ensure the installation accuracy of the frame; The frame 206b is inserted into the end of the base (made of copper alloy with heat dissipation fins). The fins have curved edges (to avoid scratching the wires). The bottom is threaded to the knob 206f (a plastic insulated knob). Rotating the knob 206f can finely adjust the extension length of the frame to adapt to the contact requirements of wires of different diameters. The insulating post 206c and the electrode 206d are fixed to the inner wall of the frame. The insulating post (made of ceramic, high voltage resistant) is fixed to the end of the electrode 206d (made of copper, silver-plated to reduce contact resistance). One end of the electrode 206d is connected to the terminal 206e, and the other end is used to connect to the external line. A set of terminals is electrically connected to the main body 102 of the energy meter through wires to realize the conduction of the metering circuit.
[0046] When in use, start the drive motor of the connecting component 200 (or manually rotate the synchronous belt pulley, or drive the main moving plate 202 to move by the electric push rod), the synchronous belt 209 rotates clockwise, the upper end of the synchronous belt 209 pulls the main moving plate 202 to slide along the main slide rail 207 toward the wiring area, and the wiring connection seat 206 of the main moving plate moves closer to the external line side; the lower end of the synchronous belt pushes the push plate 212 to slide along the secondary guide rail 214, and the push plate drives the secondary moving plate 205 to slide along the arc groove of the guide plate 203 through the nest 211 and the guide rod 210, and the wiring connection seat 206 of the secondary moving plate 205 moves closer to the main moving plate 202 side synchronously.
[0047] When the main and auxiliary moving plates slide to the preset position (positioned by a limit switch), the pole pieces 206d of their wiring connectors 206 precisely align (the contact pressure is preset by the knob 206f). The external circuit forms a conductive loop with the energy meter body 102 through the pole pieces and the wiring terminal 206e, and the energy meter begins metering (the display shows parameters such as voltage, current, and power). Once the alignment is locked, the synchronous belt drive motor stops, and the main slider 208 and auxiliary slider 215 are fixed in position by their built-in locking mechanism (ball bearing positioning) to prevent the moving plates from shifting due to vibration and ensure alignment stability.
[0048] The status monitoring connector 206 has a built-in temperature sensor (NTC material, temperature range -50℃~125℃) at the electrode to monitor the contact temperature in real time. If the temperature is >60℃ (overheating due to poor contact), the energy meter will trigger an audible and visual alarm to prompt maintenance personnel to check the connection status.
[0049] When the electricity meter needs maintenance, the synchronous belt 209 is rotated counterclockwise by the drive component. The synchronous belt 209 drives the main moving plate 202 away from the wiring area, the auxiliary moving plate 205 is reset along the arc groove, the pole pieces of the wiring connector 206 are separated, and the metering circuit is disconnected.
[0050] In summary, the synchronous drive of the connecting component 200 enables the rapid docking / disconnection of the wiring connector 206. During maintenance, there is no need to disconnect wires or disassemble the entire device, allowing for quick replacement of the main body 102 of the electricity meter, improving efficiency and ensuring the docking accuracy of the wiring connector. The knob of the wiring connector 206 can finely adjust the frame to accommodate wires of different diameters, adapt to different installation spaces inside the housing, and is compatible with different specifications of the main body 102 of the electricity meter, making it suitable for temporary power supply, maintenance, and other scenarios.
[0051] Example 3 Reference Figures 1-7 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a method for using an energy meter with a split electrical connection, including the following steps: Step 1: Pre-installation preparation and safety check; Tools and Environment Preparation: Prepare a Phillips screwdriver, insulated gloves (500V withstand voltage), and a spirit level; ensure that the installation location is a dry and ventilated place, and that the VESA mounting holes on the back of the housing 101 match the wall bracket; Equipment integrity check: After unpacking, check that the housing 101 of the metering component 100 has no cracks, and the cover plate 103 / sealing plate 104 is in good condition; the main slide rail 207 and synchronous belt 209 of the connecting component 200 are not deformed, and the pole piece 206d of the wiring connector 206 is not oxidized (if there is oxidation, gently wipe it with fine sandpaper until the metal luster is exposed). Safety precautions: Before operation, confirm that the external power supply line has been disconnected (use an electric detector to check that there is no voltage on the live wire), and operators should wear insulated gloves and goggles to avoid working on live wires; Step 2: Connect the external line to the incoming line; Unlock the connector: Press the elbow clamp 111 on the side wall of the housing 101, push the push block 110 to squeeze the locking block 108 until you hear a "click" sound (the locking block disengages from the slot of the connector male head 107), and keep the elbow clamp pressed. Wire pretreatment: Take the external power wire (live wire and neutral wire), strip the insulation layer at the end, and expose the conductor without burrs (wrap the burrs with insulating tape to prevent scratches). Male connector wiring and locking: Insert the prepared wires into the corresponding wiring holes of the male connector 107 (live wire to L terminal, neutral wire to N terminal), and tighten the fixing bolts with a screwdriver; loosen the elbow clamp 111, align the male connector with the female connector 106 inside the limit block 105, and insert it axially until the locking block 108 resets and locks (you will hear a "click" sound again), and gently pull the male connector to confirm that it is not loose; Step 3: Split-type electrical connection and docking operation; Start the drive system: Connect the internal auxiliary power supply of the energy meter, press the "Dock Start" button inside the housing 101 (or send a docking command via remote control), the synchronous belt pulley motor starts, and the synchronous belt 209 rotates clockwise; Observe the docking process: Through the transparent cover plate 103, observe the main moving plate 202 sliding along the main slide rail 207 towards the wiring area, and the auxiliary moving plate 205 synchronously approaching along the arc groove of the guide plate 203; when the moving plate is in place, the limit switch is triggered, and the motor stops automatically; Confirm successful connection: Check that the electrode 206d of the wiring connector 206 is completely in contact (without obvious gaps), the display screen of the main body 102 of the energy meter lights up, showing the current voltage and current values (such as 220V, 0.5A), and the status light (green) is constantly on, indicating that the separate electrical connection is conductive; Step 4: Equipment operation and parameter verification; Power supply test: Close the main switch of the external line, slowly apply the voltage to the rated value (such as 220V), and observe whether the electricity meter display is stable (no flickering or jumping). The metering data should be normal within 3 minutes. Contact status monitoring: Check the temperature of the wiring connector through the built-in system of the electricity meter (or remote platform) (normal ≤40℃). If the temperature of a connector is >50℃, press the "fine adjustment" button and adjust the extension length of the frame 206b by turning the knob 206f (1 / 4 turn each time) until the temperature drops to the normal range. Sealing and protection check: Confirm that the cover plate 103 and the sealing plate 104 are fully inserted into the housing groove (without gaps at the edges), the ventilation holes are not blocked, and ensure the IP54 protection rating (dust protection and splash protection). Step 5: Routine maintenance and status check; Regular cleaning: Every 3 months after power off, wipe the surface of housing 101 and the inside of cover 103 with a dry, soft cloth (to remove dust and avoid affecting observation); blow the ventilation holes with compressed air to prevent poor heat dissipation; Connection status inspection: Monthly check the wiring connector 206 for displacement and the timing belt 209 for looseness through the transparent cover (press the belt with your finger). If loose, adjust the tension of the timing belt pulley. Data calibration: Contact the metrology department annually and connect to the calibration equipment through a dedicated interface to verify the metering accuracy. The calibration process does not require disassembling the split connection structure; it can be operated directly through the calibration button on the main body 102 of the electricity meter. Step Six: Equipment Disassembly and Replacement Operations; Separate connection: Press the "Separate" button (or send a separation command remotely), the synchronous belt pulley motor reverses, and the synchronous belt 209 drives the main moving plate 202 and the auxiliary moving plate 205 to reset (away from the wiring area). After the motor stops, confirm that the pole piece 206d is completely separated. Disassembly at the inlet: Press the elbow clamp 111 to unlock the connector, pull out the male connector 107, and wrap the end of the wire with insulating tape (to prevent electric shock); if long-term disassembly is required, install a dust plug at the inlet of the limit block 105; Component replacement: If the wiring connector 206 needs to be replaced, use a screwdriver to remove the fixing bolts between the main moving plate 202 / sub-moving plate 205 and the wiring connector, replace with a new part of the same specification, and then install in reverse order to ensure that the electrode 206d is aligned.
