Description

Technical Field

[0001] This invention belongs to the field of meter box technology, and particularly relates to a modular meter that is easy to wire. Background Technology

[0002] Modular electricity meters are a new type of smart meter that adopts a "building block" architecture. They break down traditional single electricity meters into multiple functional modules that can be replaced independently and combined flexibly, such as metering, management, and communication. Existing modular meters are generally fixed in a box or inside a wall. During installation, the position of the modular meter needs to be fixed first, and then the wiring needs to be done. The operable position is limited, and the wiring steps are relatively cumbersome. It is necessary to connect the wires to each point and tighten them with bolts. This not only results in low installation efficiency but also a poor installation experience. In order to avoid the above situation, a modular meter that is easy to wire is provided. Summary of the Invention

[0003] This invention provides a modular electricity meter that is easy to wire, aiming to solve the problems of existing modular electricity meters, which are generally fixed in a box or inside a wall. During installation, the position of the modular electricity meter must be fixed first, and then the wiring can be done. The operable position is limited, and the wiring operation is relatively cumbersome. It is necessary to wire each point one by one and tighten it with bolts. This not only results in low installation efficiency but also a poor installation experience.

[0004] The present invention is implemented as follows: a modular electricity meter that is easy to wire includes a modular electricity meter: a mounting base assembly is connected to the outer wall of the modular electricity meter; an external power connection mechanism is provided at the bottom of the modular electricity meter; a pull rope and a limiting roller are embedded in the inner wall of the modular electricity meter; an upper locking shaft assembly is embedded in the upper inner wall of the modular electricity meter; an internal power connection mechanism is provided in the inner wall of the modular electricity meter; a pull ring is fixedly connected to one end of the pull rope; and a locking assembly is provided in the inner wall of the modular electricity meter. The upper locking shaft assembly includes a lower gasket fixedly disposed on the inner wall of the modular meter. A spring is connected to the upper outer wall of the lower gasket, and a locking shaft is connected to one end of the spring. The upper end of the locking shaft is inserted into the mounting base assembly. The locking shaft has an upper washer fixedly connected to its outer wall, and the two ends of the spring are fixedly connected to the upper washer and the lower washer respectively. The top of the lower washer has an insert. The spring is set on the outer wall of the locking shaft and the insert, and the outer wall of the locking shaft and the inner wall of the insert are in close sliding connection. Wherein, the end of the pull rope away from the pull ring is fixedly connected to the outer wall of the upper pad, and the outer wall of the upper pad is vertically slidably connected to the inner wall of the modular meter. The outer wall of the limiting roller is arc-shaped and concave, and it fits tightly with the outer wall of the pull rope, thus providing a semi-enclosed limiting effect on the outer wall of the pull rope. In use, pull the ring outward, and the pull rope moves downward along the inner wall. During the movement of the pull rope, the pull rope remains in contact with the limit roller. Pulling the rope down causes the upper pad to slide downward along the inner wall of the modular meter, and the locking shaft moves out of the inner wall of the mounting base assembly, releasing the position lock between the shaft and the mounting base assembly. When the pull rope is released, the locking shaft moves upward and into the center under the action of the spring and tension spring, and the locking relationship is re-established.

[0005] Preferably, the internal power connection mechanism includes a power connection component embedded in the inner wall of the modular meter, a connecting plate is inserted into the inner wall of the power connection component, and multiple reset components are symmetrically fixedly connected to the upper outer wall of the power connection component; As shown in Figures 3-4, the reset component includes a reset plate fixedly connected to the outer wall of the power connection assembly.

When one set of conductive and insulating sheets is damaged, the connecting socket is pulled out from the corrugated groove plate, the position is adjusted and the corrugated groove plate and connecting socket are reinstalled, and the position of the conductive and insulating sheets is moved and replaced. The connection is then locked with locking bolts.

The connector is inserted into the corrugated slot through a corrugated slot and a corrugated groove plate, and the corrugated slot has equidistant parallel corrugations. During use, the conductive sheet and the insulating sheet are placed between the internal connecting wires of the modular meter. When the rope is pulled down, the connecting component moves downward against the tension spring, the conductive sheet is disconnected from the internal connecting wires on both sides, and the insulating sheet cuts into the internal connecting wires on both sides. The modular meter is in an internal open circuit state, which is conducive to the installation of the modular meter circuit.

Multiple independent fixed contact pieces are embedded in the arc-shaped inner wall, and the independent fixed contact pieces are connected to the external extension wire. The lower outer fixing seat has a fixing hole on its outer wall, which facilitates the fixing of the external electrical socket assembly in the mounting box or on the inside of the wall.

[0009] Preferably, the mating plug-in assembly includes a lower inner connecting seat fixedly connected to the inner wall of the modular meter, a plurality of movable connecting pieces are inserted into the inner wall of the lower inner connecting seat, and an arc-shaped locking plate is fixedly connected to the bottom of the lower inner connecting seat by threads, and the outer wall of the arc-shaped locking plate is tightly fitted with the movable connecting pieces.

By setting up an external power supply mechanism: the external power supply mechanism simplifies the tedious steps of "connecting wires point by point and tightening them with bolts" in the background technology to a plug-in connection that can be turned on and off by flipping, which significantly reduces the difficulty of on-site wiring and the probability of errors. The internal power connection mechanism is designed to automatically switch the internal circuitry on and off by connecting the power connection components and the corrugated plug-in components, and by linking them with the pull rope. This mechanism cuts off the internal electrical circuit of the modular meter before wiring operations, providing double protection for operational safety.

[0019] This invention provides a modular electricity meter that is easy to wire, including a modular electricity meter 1: the outer wall of the modular electricity meter 1 is connected to a mounting base assembly 9, the bottom of the modular electricity meter 1 is provided with an external power connection mechanism 7, the inner wall of the modular electricity meter 1 is embedded with a pull rope 2 and a limiting roller 3, the upper inner wall of the modular electricity meter 1 is embedded with an upper locking shaft assembly 4, the inner wall of the modular electricity meter 1 is provided with an internal power connection mechanism 5, one end of the pull rope 2 is fixedly connected to a pull ring 6, and the inner wall of the modular electricity meter 1 is provided with a locking assembly 8; The upper locking shaft assembly 4 includes a lower gasket 402 fixedly installed on the inner wall of the modular meter 1.

Among them, the outer wall of the limiting roller 3 is arc-shaped and concave, and it fits tightly with the outer wall of the pull rope 2, thus achieving a semi-enclosed limiting effect on the outer wall of the pull rope 2. In use, when the pull ring 6 is pulled outward, the pull rope 2 moves downward along the inner wall. During the movement of the pull rope 2, the pull rope 2 remains in contact with the limit roller 3. When the pull rope 2 is pulled down, it causes the upper pad to slide downward along the inner wall of the modular meter 1. The locking shaft 401 moves out of the inner wall of the mounting base assembly 9, releasing the position lock between it and the mounting base assembly 9. When the pull rope 2 is released, under the action of the spring 403 and the tension spring, the locking shaft 401 moves upward and enters the middle, and the locking relationship is re-established. The internal power connection mechanism 5 includes a power connection component 501 embedded in the inner wall of the modular meter 1. A connecting insert plate 502 is inserted into the inner wall of the power connection component 501, and multiple reset pieces 503 are symmetrically fixedly connected to the upper outer wall of the power connection component 501. As shown in Figures 3-4, the reset component 503 includes a reset plate fixedly connected to the outer wall of the power connection component 501. The outer wall of the reset plate is fixedly connected to a tension spring and a guide slide, and is connected to the modular meter 1 through the tension spring. The power connection assembly 501 includes a connection socket 5011, an insulating sheet 5014 is fixedly connected to the inner wall of the connection socket 5011, and a conductive sheet 5015 is fixedly connected to the inner wall of the connection socket 5011. The conductive sheet 5015 and the insulating sheet 5014 are multiple, and each pair of conductive sheets 5015 and insulating sheets 5014 connected vertically is a group, and multiple groups of conductive sheets 5015 and insulating sheets 5014 are arranged horizontally at equal intervals. The multiple sets of conductive sheets 5015 and insulating sheets 5014 are arranged horizontally at equal intervals. When one set of conductive sheets 5015 and insulating sheets 5014 is damaged, the connecting socket 5011 is pulled out from the corrugated groove insert plate 5021, the position is adjusted and the corrugated groove insert plate 5021 and connecting socket 5011 are reinstalled, and the position of one set of conductive sheets 5015 and insulating sheets 5014 is moved and replaced. The set is then locked by the locking bolt 5013. Among them, such as Figure 4 As shown, the conductive sheet 5015 is a circular conductive sheet, and the conductive sheet 5015 and the insulating sheet 5014 are connected and aligned, and the connecting socket 5011 is made of insulating material. The inner wall of the connector 5011 is provided with a corrugated slot 5012, and a locking bolt 5013 is provided horizontally on the inner wall of the connector 5011. The connecting insert plate 502 includes a corrugated groove insert plate 5021, and a connecting block 5022 is fixedly connected to the outer wall of the corrugated groove insert plate 5021. The outer wall of the connecting block 5022 is fixedly connected to the pull rope 2. The connecting socket 5011 is fitted into the corrugated slot plate 5021 through the corrugated slot 5012, and the corrugated slot 5012 has equidistant parallel corrugations. In use, the conductive sheet 5015 and the insulating sheet 5014 are arranged between the internal connecting wires in the modular meter 1. During the pulling of the rope 2, the connecting component 501 moves downward against the tension spring, the conductive sheet 5015 is disconnected from the internal connecting wires on both sides, and the insulating sheet 5014 cuts into the internal connecting wires on both sides. The modular meter 1 is in an internal open circuit state so that the circuit of the modular meter 1 can be installed. The external power supply mechanism 7 includes an external power socket assembly 701 and a mating power plug assembly 702. The external power socket assembly 701 includes a lower external fixing seat 7011, a lower external connecting seat 7012 fixedly connected to the outer wall of the lower external fixing seat 7011, a plurality of external extension wires 7013 fixedly connected to the bottom of the lower external fixing seat 7011, and a plurality of protective shields 7014 fixedly connected to the outer wall of the lower external fixing seat 7011, and the protective shields 7014 and the external extension wires 7013 are configured to cooperate. Among them, the inner wall of the lower outer connector 7012 is arc-shaped and is configured to cooperate with the lower inner connector 7021 and the movable contact piece 7022. Multiple independent fixed contact pieces are embedded in the arc-shaped inner wall, and the independent fixed contact pieces are connected to the external extension wire 7013. The lower outer fixing seat 7011 has a fixing hole on its outer wall, which facilitates the fixing of the external electrical socket assembly 701 in the mounting box or on the inside of the wall. The plug-in assembly 702 includes a lower inner connector 7021 fixedly connected to the inner wall of the modular meter 1. Multiple movable contact pieces 7022 are inserted into the inner wall of the lower inner connector 7021. An arc-shaped locking plate 7023 is fixedly connected to the bottom of the lower inner connector 7021 by threads, and the outer wall of the arc-shaped locking plate 7023 is tightly fitted with the movable contact pieces 7022. The outer walls of the lower inner connector 7021 and the movable contact piece 7022 are both arc-shaped, and they are used in conjunction with the lower outer connector 7012 and the independent fixed contact piece on the inner wall of the lower outer connector 7012, respectively. The external power socket assembly 701 and the matching power plug assembly 702 are used together. When the modular meter 1 is rotated outward, the plug-in component 702 slides out from the inner wall of the external socket component 701, and the movable contact piece 7022 disconnects from the independent fixed contact piece on the inner wall of the lower external connector 7012, forming an open circuit. When the modular meter 1 is rotated inward, the plug-in component 702 returns to its original position and slides into the inner wall of the external socket component 701, and the movable contact piece 7022 is attached to the lower external connector 7012, thus connecting the circuit. The locking assembly 8 includes a locking block 801 that is inserted into the inner wall of the modular meter 1. One end of the locking block 801 is fixedly connected to a locking shaft 802. The locking shaft 802 and the pull ring 6 are used together. The locking block 801 and the modular meter 1 are fixedly connected by bolts. Modular meter 1 includes an outer casing and an internal electrical structure. The internal electrical structure includes a power supply bus, internal connecting wires, functional modules, and internal connecting wires. Mounting bracket assembly 9 includes a main connecting base 901. Two connecting shafts 903 are symmetrically rotatably connected to the inner wall of one side of the main connecting base 901. The outer wall of the connecting shafts 903 is rotatably connected to the modular meter 1. A main fixing base 902 is fixedly connected to the rear side of the main connecting base 901. The outer wall of the main fixing base 902 is provided with a reserved installation hole. The inner wall of the main connector 901 is movably connected to the upper and lower outer walls of the modular meter 1. The upper end of the main connector 901 has a connecting hole on the inner wall of the side away from the connecting shaft 903. The connecting hole and the locking shaft 401 are used together.

[0020] It should be noted that since existing modular meters are generally fixed in the enclosure or inside the wall, the installation process requires fixing the position of the modular meter first and then wiring. The operable positions are limited, and the wiring steps are relatively cumbersome, requiring wiring to be done at each point and tightened with bolts. This not only results in low installation efficiency but also a poor installation experience.

[0021] Specifically, in this embodiment, the solution mainly uses the modular meter 1, mounting base assembly 9, external power connection mechanism 7, modular meter 1, pull rope 2, limit roller 3, upper locking shaft assembly 4, internal power connection mechanism 5, pull ring 6, and locking assembly 8 for setup and cooperation. In use, firstly, the mounting base assembly 9 is fixedly installed in the mounting box or inside the wall through the mounting reserved holes on the main fixing base 902. Then, the external power socket assembly 701 is fixedly installed in the mounting box or inside the wall through the lower external fixing base 7011. Note the installation position of the external power socket assembly 701 and ensure that the external power socket assembly 701 and the matching plug-in assembly 702 can be used together. Then, open the locking assembly 8, pull the pull ring 6 outward, and the pull rope 2 moves downward along the inner wall. During the movement of the pull rope 2, the pull rope 2 remains in contact with the limit roller 3. The pull rope 2 is pulled down, causing the upper pad to slide downward along the inner wall of the modular meter 1. The locking shaft 401 moves out of the inner wall of the mounting base assembly 9, releasing the position lock between it and the mounting base assembly 9. During the downward pulling of the pull rope 2, the power connection assembly 501 moves downward against the tension spring, the conductive plate 5015 is disconnected from the internal connecting wires on both sides, and the insulating plate 5014 cuts into the internal connecting wires on both sides. The modular meter 1 is in an internal open circuit state. Simultaneously, rotating the modular meter 1 outward causes the plug-in assembly 702 to slide out from the inner wall of the external connector assembly 701. The movable contact piece 7022 disconnects from the independent fixed contact piece on the inner wall of the lower external connector 7012, creating an open circuit. As needed, the power input bus in the internal electrical structure of the modular meter 1 is connected to the power input circuit, and the power cord of the appliance is connected to the external extension wire 7013. When rotating the modular meter 1 inward, the plug-in assembly 702 resets and slides into the external connector assembly 701. On the inner wall of 1, the movable contact piece 7022 is attached to the lower outer connecting seat 7012, and the circuit between the movable contact piece 7022 and the fixed contact piece is connected. Then, the pull rope 2 is released. Under the action of the spring 403 and the tension spring, the pull rope 2 moves upward, and the contact component 501 moves upward accordingly. The conductive piece 5015 is reconnected to the inner connecting wires on both sides, and the insulating piece 5014 is cut into the inner connecting wires on both sides. The modular meter 1 is internally connected. At the same time, the locking shaft 401 moves upward and enters the middle, and the locking relationship is re-established. Finally, the moving locking component 8 and the locking pin 802 pass through the interior of the modular meter 1 with the pull ring 6 inserted to lock the position of the pull ring 6.

[0022] In this embodiment, firstly, the mounting bracket assembly 9 sets the modular meter 1 as a rotatable mounting structure through the main connecting bracket 901 and the connecting shaft 903, allowing it to be flipped outwards during wiring, effectively expanding the operator's working space and avoiding the predicament of manually wiring in a narrow enclosure. Secondly, the pull rope 2, the limiting roller 3, and the upper locking shaft assembly 4 work together to form a "one-click unlocking" mechanism—pulling the pull ring 6 outwards, the pull rope 2, guided by the limiting roller 3, drives the locking shaft 401 to compress the spring 403 and slide downwards, causing it to disengage from the connecting hole of the main connecting bracket 901 and release the lock; after release, the spring 403 resets, and the locking shaft 401 automatically re-inserts, completing a rapid self-locking, completely replacing the tedious operation of tightening bolts one by one in the traditional method. More importantly, the pull rope 2 is also linked with the internal power connection mechanism 5—the internal circuit breaker is triggered synchronously during the pull-down process, allowing the wiring operation to be carried out safely in a circuit-off state without the need for additional power-off operation. Finally, the locking component 8 achieves anti-accidental locking through the locking pin 802 passing through the pull ring 6, ensuring locking reliability during long-term use. In summary, this solution integrates "unlocking—power off—flipping—wiring—resetting—power on—self-locking" into a coherent sequence of actions, significantly improving installation efficiency and user experience. In this embodiment, the external power supply mechanism 7 consists of two parts: an external power supply socket assembly 701 fixedly installed in the housing or wall, and a mating plug-in assembly 702 integrated into the bottom of the modular meter 1. The lower external connecting seat 7012 of the external power supply socket assembly 701 has an arc-shaped inner wall, with multiple independent fixed connecting plates embedded inside. These connecting plates are pre-welded and fixed to the external extension wire 7013. Similarly, the lower inner connecting seat 7021 and the movable connecting plate 7022 of the mating plug-in assembly 702 also have arc-shaped outer walls, forming a "curved surface fit" mating relationship. In actual wiring operations, operators only need to pre-connect the external extension wire 7013 to the power cord of the external appliance. This step can be completed in an open space, without being restricted by the location of the meter. Then, when the modular meter 1 is flipped outward around the connecting shaft 903, the plug-in component 702 slides out naturally from the arc-shaped inner wall of the lower outer connector 7012, and the movable contact piece 7022 separates from the fixed contact piece, achieving a physical circuit break. When flipped inward to reset, the two are pressed together again along the arc surface, and automatic alignment is achieved by relying on the arc-shaped guide. There is no need to visually align each connection point, nor is there any need to use any tools to tighten the bolts. This structure not only changes the wiring operation from "point-by-point operation" to "one-time insertion", but also increases the effective conductive area through the arc-shaped contact surface, ensuring the reliability of the connection. At the same time, the protective shield 7014 provides protection for the root of the external extension wire 7013, effectively extending its service life. In this embodiment, the internal power connection mechanism 5 consists of a power connection component 501 and a connecting insert plate 502. Multiple sets of conductive plates 5015 and insulating plates 5014 are equidistantly arranged on the inner wall of the connecting socket 5011 of the power connection component 501, and are fitted into the corrugated slot plate 5021 of the connecting insert plate 502 via a corrugated slot 5012. This structure has two significant advantages: First, the upper end of the power connection component 501 is connected to the modular meter 1 via a tension spring in the reset component 503. Simultaneously, the reset plate of the reset component 503 is linked to the upper locking shaft assembly 4 via a pull rope 2. When the operator pulls the pull ring 6 outward, the pull rope 2 pulls down, causing the power connection component 501 to move downward against the tension spring. At this time, the conductive plates 5015 disengage from the internal connecting wires on both sides of the modular meter 1, and the insulating plates 5014 simultaneously cut into the spaces between the internal connecting wires, creating a physical open circuit inside the modular meter 1. This linkage mechanism ensures that the internal circuit is automatically cut off when the meter is unlocked and flipped, effectively preventing the risk of electric shock caused by accidental contact with live parts during wiring, and providing inherent safety protection for operators. Secondly, multiple sets of conductive plates 5015 and insulating plates 5014 are arranged horizontally at equal intervals. When a set of conductive plates is damaged by oxidation, burning, or other reasons, simply pull out the connecting socket 5011 from the corrugated slot plate 5021, adjust the horizontal position, and re-insert it to switch to another set of intact conductive plates without replacing the entire power connection assembly 501, significantly reducing maintenance costs and downtime. The cooperation between the corrugated slot 5012 and the corrugated slot plate 5021 also ensures the positioning accuracy and contact stability after insertion, avoiding contact problems caused by vibration.
