[0024] On the one hand, the present invention provides a modular meter box connector, such as Figure 1 and Figure 2As shown, it includes a frame 1 and a conversion plug 2; a plurality of guide grooves are provided in the frame 1, and the conversion plug 2 can be detachably connected in the guide grooves; a current bar 201 is provided at one end of the conversion plug 2, and the current bar 201 is connected to the interface of the electric meter; a wiring hole 206 is provided at the other end of the conversion plug 2, and the external wire extends into the conversion plug 2 through the wiring hole 206; a clamping mechanism is also provided in the internal cavity of the conversion plug 2, and the clamping mechanism is connected to the current bar 201, and the clamping mechanism is made of conductive material, and the clamping mechanism is used to clamp the external wire so that the external wire is fixed in the conversion plug 2, and the external wire is connected to the current bar 201 through the clamping mechanism to be connected to the interface of the electric meter.

[0025] The modular meter box connector provided in the present application facilitates the installation and replacement process of the conversion plug 2 by providing a guide groove and a detachable conversion plug 2, and the installed frame 1 can be directly connected to the meter interface, so that the user can quickly complete the installation or replacement work; a clamping mechanism made of conductive material is provided in the conversion plug 2, which is used to firmly clamp the external wire, ensuring the stability and safety of the electrical connection, reducing the risk of failure due to poor contact, and ensuring stability in long-term use; the modularly designed connector can adapt to meter interfaces of different specifications, and different conversion plugs 2 can be customized for different meter interfaces, maintaining the versatility of the frame 1 and other components, thereby reducing inventory management and maintenance costs, and at the same time, a specific number of conversion connectors can be selectively connected according to the number of meter interfaces, which has strong flexibility.

[0026] Specifically, in the above embodiment, Figure 3 and Figure 4 As shown, the clamping mechanism includes a self-locking spring 202, which is a C-shaped structure. The self-locking spring 202 includes a top section 2021, a vertical connecting section 2022 and a clamping section 2023 connected in sequence; a connecting claw is provided at one end of the vertical connecting section 2022, and the connecting claw is connected to the current bar 201 and fixed to the top of the internal cavity of the conversion plug 2; after the external wire extends into the conversion plug 2 through the wiring hole 206 and abuts against the top section 2021, the clamping section 2023 pops out to clamp the external wire and fix it in the internal cavity of the conversion plug 2.

[0027] The clamping mechanism specifically includes an elastic self-locking spring 202, which is in a C-shaped structure, including a top section 2021, a vertical connecting section 2022 and a clamping section 2023 connected in sequence, the top section 2021 is close to the top of the internal cavity and is placed horizontally, the vertical connecting section 2022 is arranged in the vertical direction, and a connecting claw is arranged at one end of the vertical connecting section 2022 close to the top of the internal cavity, and the connecting claw is fixed to the top of the internal cavity by clamping with the current bar 201, so that the self-locking spring 202 can be stably fixed. The clamping section 2023 is fixed in the internal cavity, and the connecting claw is also connected to the current bar 201, so that the external wire can be connected to the current bar 201 through the conductive clamping mechanism, and the clamping section 2023 is close to the top section 2021 under normal conditions, and a gap is left between the clamping section 2023 and the side wall of the internal cavity to allow the external wire to extend into. After the external wire abuts against the top section 2021, the clamping section 2023 springs outward to press the external wire onto the side wall of the internal cavity of the conversion plug 2, and at the same time, the external wire is always in contact with the clamping mechanism, and then connected to the current bar 201.

[0028] In this embodiment, the user inserts the external wire into the conversion plug 2 through the wiring hole 206, and the external wire continues to be pushed in the vertical direction until the external wire abuts against the top section 2021, and under the elastic action, the clamping section 2023 pops outward, pressing the external wire against the side wall of the internal cavity. At this time, the external wire is connected to the current bar 201 through the clamping mechanism and connected to the meter interface; based on the clamping mechanism provided in the present application, after the external wire is inserted, the clamping process is automatically completed without the need for additional tools or complicated operations, which greatly simplifies the installation steps, and uses the spring sheet to press the external wire to ensure the stability of the external wire connection.

[0029] Furthermore, the current bar 201 includes a terminal 2011, a top connecting bar 2012 and a vertical dividing bar 2013 connected in sequence; the terminal 2011 is arranged at the top of the conversion plug 2 in the vertical direction and is connected to the meter interface; the top connecting bar 2012 is arranged at the top of the internal cavity of the conversion plug 2 in the horizontal direction and is connected to the connecting claw; the vertical dividing bar 2013 is arranged in the internal cavity of the conversion plug 2 in the vertical direction to divide the internal cavity into two placement spaces.

[0030] In this embodiment, the structure of the current bar is further split, such as Figure 3 and Figure 4As shown, the current bar 201 presents a vertically placed Z-shaped structure, wherein the terminal 2011 is cylindrical and is used to connect to the meter interface; the top connecting bar 2012 is arranged in the horizontal direction at the top of the internal cavity of the conversion plug 2 and is connected to the connecting claw. On the one hand, it is used to fix the self-locking spring 202 by snapping the connecting claw, and on the other hand, it plays a role in diverting current; the vertical dividing bar 2013 is arranged in the vertical direction, dividing the internal cavity into two parts, and the side close to the frame 1 is used to place the clamping mechanism, and the wiring hole 206 of the conversion plug 2 is also arranged on one side of the clamping mechanism, and the external wire extends into and out through the wiring hole 206 on one side of the internal cavity.

[0031] Furthermore, the modular meter box connector also includes a wire withdrawal mechanism; the wire withdrawal mechanism abuts against the clamping section 2023, and the wire withdrawal mechanism is used to apply external force to the clamping section 2023 so that the clamping section 2023 rebounds to loosen the external wire, and the external wire withdraws from the conversion plug 2 through the wiring hole 206.

[0032] Among them, the modular meter box connector includes a wire withdrawal mechanism corresponding to the clamping mechanism, which makes it easy for the user to remove the wire from the conversion plug 2 when the external wire needs to be replaced or maintained; specifically, the wire withdrawal mechanism directly abuts against the clamping section 2023, and mainly applies external force to make the clamping section 2023 rebound, thereby loosening the fixation of the clamped external wire. When the external wire needs to be withdrawn, the wire withdrawal mechanism is activated by manual pressing, rotation or other mechanical actions, and a force in the opposite direction is applied to the clamping section 2023, so that the clamping section 2023 leaves the position where the wire was clamped before, thereby releasing the clamping force on the external wire, so that the external wire can be easily pulled out from the wiring hole 206.

[0033] In this embodiment, compared with the traditional meter connection method that requires the use of tools to loosen screws or other types of fixing devices, the design of the wire withdrawal mechanism allows the user to complete the insertion and removal of the wires without any tools, greatly improving work efficiency and convenience, reducing safety hazards caused by misuse of tools, and reducing the risk of human error; when maintenance or replacement of wires is required, the wire withdrawal mechanism can quickly remove the wires from the connector, saving time and labor costs.

[0034] Further, such as Figure 3 and Figure 4As shown, the line withdrawal mechanism includes a line withdrawal button 203, a spring 204 and abutment 205; the line withdrawal button 203 is arranged on the side of the vertical dividing strip 2013 away from the self-locking spring 202, the force-bearing surface of the line withdrawal button 203 is arranged on the outside of the conversion plug 2, and the connecting surface of the line withdrawal button 203 is elastically connected to the vertical dividing strip 2013 through the spring 204; one side of the abutment 205 is connected to the line withdrawal button 203, and the other side of the abutment 205 passes over the vertical dividing strip 2013 and abuts against the clamping section 2023; when the force-bearing surface of the line withdrawal button 203 is acted upon by an external force, pushing the abutment 205 to press the clamping section 2023, the clamping section 2023 rebounds and releases the external wire.

[0035] Among them, the line withdrawal mechanism is specifically arranged on the other side of the vertical dividing bar 2013 relative to the clamping mechanism, and specifically includes a line withdrawal button 203, a spring 204 and an abutment 205. The line withdrawal button 203 specifically includes a force-bearing surface and a connecting surface. The force-bearing surface is specifically arranged on the outer side of the conversion plug 2, and is used to bear the external force applied by the user, and the connecting surface is connected to the vertical dividing bar 2013 through the spring 204, so that the line withdrawal button 203 can move in the horizontal direction under the external force applied by the user, and the abutment 205 directly abuts against the clamping section 2023 after crossing the vertical dividing bar 2013. The abutment 205 can move in the horizontal direction synchronously with the line withdrawal button 203 under the force of the line withdrawal button 203, thereby pushing the clamping section 2023 to rebound and release the external wire.

[0036] In this embodiment, when the external wire has been clamped by the clamping mechanism, if the user wants to release the external wire and no longer connect the external wire to the electric meter, the wire withdrawal mechanism can be used to withdraw the wire. The user applies external force to the force-bearing surface of the wire withdrawal button 203, so that the connecting surface of the wire withdrawal button 203 pushes the abutment 205 to move, and then pushes the clamping section 2023 to move toward the top section 2021, thereby releasing the external wire and disconnecting it.

[0037] Specifically, in the above embodiment, Figure 5 As shown, the other end of the conversion plug 2 is provided with four wiring holes 206, and the wiring holes 206 are used to connect the live wire of the power supply, the neutral wire of the power supply, the live wire of the load, and the neutral wire of the load, respectively.

[0038] Among them, the live wire of the power supply is the end where the current outputs from the power supply, usually associated with a higher electric potential, and is where the current flows into the circuit; the neutral wire of the power supply is the loop line in the circuit, used to provide a path to complete the current cycle back to the power supply; the live wire of the load refers to the live wire that is drawn out from the power supply and connected to the load after passing through a switch or other control device, and is used to deliver current to electrical equipment; the load neutral wire is connected from the power neutral wire to the load, providing a return path so that current can flow from the load back to the power supply to form a closed circuit.

[0039] In this embodiment, by providing a dedicated wiring hole 206 for each type of wire, and also accompanying it with clear color coding or marking, the possibility of incorrect connection can be reduced, thereby avoiding the risk of short circuit or other electrical failure, improving the safety of the entire system, and when system maintenance or troubleshooting is required, the clear wiring layout can quickly locate the problem, shortening maintenance time and reducing maintenance costs.

[0040] Specifically, in the above embodiment, an indicator light is further provided on the outer side of the frame body 1 , the indicator light is connected to the terminal 2011 , and the indicator light is used to indicate the connection status of the external wire.

[0041] Among them, an indicator light is installed on the outside of the frame 1, and the indicator light is connected to the internal terminal 2011 through a circuit. During specific use, when the external wire is correctly connected to the corresponding terminal 2011, the indicator light will light up or change color to intuitively display whether the wire has been successfully connected and the quality of the connection.

[0042] In this embodiment, the indicator light can instantly feedback the status of the wire connection, so that the user can quickly determine whether the connection is successful and avoid problems caused by improper connection. For example, during the installation process, if the indicator light does not light up, the user knows that the connection needs to be rechecked and adjusted. Confirmation of the correct connection helps prevent electrical faults, such as short circuits or poor contact. In addition, clear visual prompts reduce the possibility of misoperation and further improve the safety of the system. When debugging the system, technicians can quickly understand the connection status of each part by observing the status of the indicator light, without having to use tools such as a multimeter to detect the connection status of each wire one by one, thereby greatly saving time and energy. In long-term operation, the indicator light continuously provides information about the connection status to help users discover potential problems in a timely manner. Further combined with smart sensors and communication modules, the status information of the indicator light can also be transmitted to the remote monitoring system to achieve remote monitoring and management of the meter box status, which is particularly suitable for power management systems in widely distributed power grid facilities or large industrial environments.

[0043] Specifically, in the above embodiment, a plurality of signal holes 207 are further provided at the other end of the conversion plug 2 .

[0044] In this embodiment, if Figure 5As shown, at the other end of the conversion plug 2, i.e., the same end as the wiring hole 206, there are also multiple signal holes 207, which can be used to transmit various types of signals, such as data signals, control signals, etc., so as to realize the simultaneous transmission and management of multiple signals, so that the conversion plug 2 can support the interconnection between more complex electrical and electronic equipment; the setting of the signal hole 207 increases the functionality of the conversion plug 2, which is not limited to power transmission, but can also carry out data communication or other types of signal transmission, and the setting of multiple signal holes 207 improves the compatibility of the equipment, allowing different types of equipment or modules to be connected without the need for additional adapters or converters. This makes system integration simpler and more efficient, and at the same time integrates power transmission and signal transmission into one conversion plug 2, reducing the complexity of wiring. When it is necessary to add new functions or replace certain modules, it is only necessary to adjust the corresponding signal hole 207 connection without making large-scale changes to the entire system, which greatly simplifies maintenance and upgrade work.

[0045] Specifically, in the above embodiment, a compensation panel is further provided on the frame 1, and a bracket is further connected to a side of the frame 1 close to the installation surface of the meter box.

[0046] In this embodiment, the compensation panel is generally made of a sturdy and durable material, such as metal or high-strength plastic, which can effectively prevent external environmental factors, such as dust, moisture, corrosive substances, etc., to avoid their impact on internal electrical components and improve the stability of device operation; the compensation panel can also be used for lead sealing, and a special position can be provided on the compensation panel for installing lead seals or other types of sealing devices to ensure that unauthorized personnel cannot easily open or tamper with the equipment; at the same time, the compensation panel can be transparent for user observation, and can also be disassembled and reinstalled when the compensation panel needs maintenance or inspection, thereby improving maintenance efficiency.

[0047] In another embodiment, a bracket is provided on one side of the frame 1 itself close to the installation surface of the meter box, and the bracket is used to provide stable installation and fixation, so that the meter box as a whole can operate safely and reliably. The bracket is usually made of high-strength material to ensure that it has sufficient mechanical strength and durability. The specific bracket can be fixed to the wall, the ground or other supporting structure by bolts, screws or other fasteners. In some special application scenarios, the bracket can also be designed to be adjustable for precise alignment and fine-tuning.

[0048] Another aspect of the present invention provides an electric meter box, comprising an electric meter box body and a modular electric meter box connector as described above; the modular electric meter box connector is arranged at the bottom of the electric meter box body, and the current bar 201 of the modular electric meter box connector is connected to the interface of the electric meter box body.

[0049] The electric meter box provided by the present invention is provided with a modular electric meter box connector on the basis of the electric meter box body, so that users can easily complete the operation during the installation and disassembly process, ensure the safety and reliability of the electric meter connector during use, and prevent accidental disconnection and improper operation; and meet the requirements of the overall plug-in transfer of the overall secondary circuit used for measuring current, etc., by connecting the multi-way terminal, the external circuit is connected to the new electric meter, the metering circuit enters a normal operating state, and the overall transfer of the metering circuit is realized in the process, thereby realizing the automatic plug-in and overall transfer of the metering meter circuit of the external mutual inductor and the power supply during the transformation and wiring, and performing on-site rapid compatibility replacement for the electric meter box, thereby improving the overall installation and operation and maintenance efficiency.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
