This ensures the wires are arranged regularly during meter replacement, reducing the possibility of wire contact and tangling, thus maintaining better operational safety when removing old meters and installing new ones. The piercing element penetrates the wire insulation layer to establish an electrical connection with the conductor, and further restricts the wire's position within the hole through compression, allowing short-circuited wires to reliably complete the electrical connection and maintain temporary power supply. The semi-enclosed structure of the hole, combined with the locking effect of the fixing element, keeps the base and housing stable during operation, improving the stability of wire arrangement and the convenience of meter replacement. When inserting wires into the new meter terminals, the neatly arranged wire ends allow for smoother simultaneous insertion into the terminal holes, improving wiring efficiency and reducing electrical risks caused by tangled wires or poor contact. Overall, this technical solution effectively improves operational safety, wire arrangement controllability, and electrical connection reliability in uninterrupted meter replacement operations, making the replacement process more stable and efficient.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0019] In existing electricity systems, the electricity meter, as a key metering device connecting the power grid and the user side, is the only legally valid metering instrument in the billing process. Because electricity meters may damage or reach the end of their service life during long-term operation, they often need to be replaced. Traditional replacement methods typically rely on power outages: disconnecting the power supply, removing the old meter, installing the new meter, and then restoring power. While this method ensures operational safety, it causes a power outage.

[0020] To solve the power outage problem, the industry generally adopts the method of replacement without power outage. During the replacement process, the four wires originally connected to the electricity meter (L1 connected to the grid, L2 connected to the user, N1 connected to the grid, and N2 connected to the user) are short-circuited respectively. By short-circuiting L1 and L2 and N1 and N2, the power supply to the line is maintained. Then the old electricity meter is removed and the new electricity meter is installed. Finally, the short-circuiting wires are removed to put the new meter into operation.

[0021] The applicant found through research that although the method is feasible in principle, it has insurmountable technical defects in actual operation: on the one hand, all four wires are covered with insulation, and the exposed metal section is limited, making it difficult to perform short-circuiting operations without power interruption and posing a risk of electric shock; on the other hand, after the old electricity meter is removed, the four wire ends of L1, L2, N1, and N2 lose their fixed points and will be scattered irregularly in a narrow space, which can easily lead to contact between the wire ends, especially accidental short circuits between the live wire and the neutral wire, posing a major safety hazard.

[0022] Furthermore, when installing a new electricity meter, these tangled wire ends are difficult to insert stably and accurately into the terminal holes of the new electricity meter at the same time, which greatly increases the difficulty of operation and significantly increases the risk of faults such as misconnection and loose connection.

[0023] It is evident that the existing uninterrupted meter replacement method has significant shortcomings in terms of both safety and operability, and there is an urgent need for an improved solution that can safely, reliably, and conveniently replace electricity meters without power interruption.

[0024] Based on this, this application provides a wiring device; please refer to [link / reference]. Figure 1 and Figure 2 The wiring device includes a base 1, a housing 2, a fixing element 4, and a piercing element 5.

[0025] For example, the base 1 has a plurality of first grooves 31, the housing 2 is movably connected to the base 1, and the housing 2 has a plurality of second grooves 32. Each first groove 31 and a second groove 32 are configured to jointly form a hole 3 for inserting wires. The hole 3 can circumferentially cover the wires, which can limit the tendency of the wires to move radially to a certain extent, so that the wires present a more stable arrangement during meter replacement, which helps to reduce the possibility of the wires coming into contact with each other.

[0026] For example, four first grooves 31 are provided along the length of the base 1, and four second grooves 32 are provided along the length of the housing 2. The four first grooves 31 and the four second grooves 32 can be enclosed to form four holes 3, which can be respectively embedded with four wires, namely L1, L2, N1, and N2. It can be understood that during the meter replacement operation, the base 1 is placed below the four wires at the lower end of the single-phase energy meter, so that each wire naturally falls into its corresponding first groove 31 under the action of gravity, thereby establishing the basic arrangement relationship of the wires in the initial stage.

[0027] In some embodiments, the cross-sectional shape of the first groove 31 and the second groove 32 is semi-circular. This combination results in a regular circular orifice 3, which restricts the movement range of the wires in three-dimensional space, making it easier to maintain the relative distance between the wires and reducing the risk of contact between adjacent wires to some extent. The fixing member 4 stabilizes the combination of the base 1 and the housing 2, ensuring that the orifice 3 maintains a stable shape throughout the meter replacement process, thereby reducing the probability of wire position changes due to operational vibrations.

[0028] For example, the fastener 4 is provided in either the base 1 or the housing 2, and the fastener 4 is used to fix the base 1 and the housing 2. Specifically, the fastener 4 can achieve detachable fixation of the two by screwing, snapping or other mechanical connection methods, so that each set of first groove 31 and second groove 32 remains in contact under the action of the fastener 4, thereby maintaining the overall shape and stability of the hole 3.

[0029] Exemplarily, the piercing element 5 is movably connected to either the base 1 or the housing 2, and the piercing element 5 is configured to electrically connect with the wire after passing through the wire's insulation when the wire is embedded in the hole 3. Specifically, the piercing element 5 can be inserted radially into the hole 3 by manual pressing or applying force with a tool, causing the piercing element 5 to penetrate the wire's insulation and contact the conductor's metal portion, thereby forming an electrical connection path with the wire. Simultaneously with the insertion of the piercing element 5, its own structure exerts a certain clamping effect on the wire, restricting the axial and radial movement of the wire within the hole 3.

[0030] Furthermore, after penetrating the insulation, the piercing element 5 comes into contact with the metal body of the wire. This structure allows the lead-out and connection point of the external wire to be formed directly at the end of the piercing element 5 away from the contact end, so that the short-circuited wire can complete the electrical connection more reliably. At the same time, the pressure of the piercing element 5 on the wire also further enhances the stability of the wire in the hole 3.

[0031] It is understandable that during the replacement of the electricity meter, the base 1 guides the wires into their respective first slots 31, resulting in a regular arrangement of the wires. Once the housing 2 is attached to the base 1 and locked by the fixing piece 4, each wire is confined within its corresponding hole 3. This hole 3, formed by the first slot 31 and the second slot 32, enhances the stability of the wire arrangement to a certain extent, preventing the wires from scattering freely after the old electricity meter is removed. The piercing piece 5, after being pressed, penetrates the insulation and establishes an electrical connection with the metal body of the wire, allowing adjacent wires to be electrically connected through external short-circuit wires. For example, L1 and L2 are electrically connected, as are N1 and N2, thus maintaining continuous power supply to the user. Because the piercing piece 5 exerts a compressive force on the wires, the position of the wires within the hole 3 is further defined, ensuring a neat arrangement of the wires after meter replacement. This arrangement facilitates the smooth simultaneous entry of all four wires into the wiring terminal holes of the new electricity meter when it is in place.

[0032] Based on this, when the old electricity meter is loosened, since all four wires are fixed inside the hole 3, their wire ends will not swing uncontrollably, making the disassembly process safer and more reliable to a certain extent. When installing the new electricity meter and inserting the metal ends of the four wires, since the wires are arranged in a regular manner in the hole 3, the four wire ends have a relatively fixed relative positional relationship, which can improve the convenience of inserting the wires into the corresponding terminals at the same time. After the new electricity meter is wired, the wires can be restored to a free state by pulling out the short-circuit wire, loosening the piercing piece 5 and opening the housing 2 structure. At the same time, by covering the insulation at the piercing point with tape, the insulation performance of this part can be enhanced.

[0033] With the above structural configuration, the wiring device plays a positive role in improving the stability of wire arrangement, simplifying the short-circuit method, and enhancing the safety of the operation during meter replacement. It improves the controllability of wire position during meter replacement, makes the electrical connection method clearer, and makes the entire meter replacement process more reliable.

[0034] In some embodiments, both the housing 2 and the base 1 are made of plastic. It is understood that plastic materials offer suitable performance in terms of insulation, processing stability, and weight control. Since the wiring device needs to directly contact the conductor at the lower end of the single-phase electricity meter during use and needs to withstand the localized concentrated load caused by the pressure of the piercing element 5 within a certain range, the advantages of plastic materials in insulation properties can, to a certain extent, improve the overall safety of the device in electrical applications, thus reducing the electrical risk when the housing 2 and base 1 are arranged near live conductors.

[0035] In some implementations, combined Figure 1 , Figure 2 The housing 2 includes an outer shell 21 and a cover plate 22. The cover plate 22 is disposed on the outer shell 21, and the piercing member 5 is movably connected to the cover plate 22. The outer shell 21 is movably connected to the base 1, and the second groove 32 is disposed on the outer shell 21. Specifically, the cover plate 22 is arranged on the side of the outer shell 21 away from the base 1, and the piercing member 5 is movably connected to the cover plate 22, so that when pressed, the piercing member 5 can enter the area corresponding to the hole 3 along the pre-opened guide structure on the cover plate 22. The movable arrangement of the piercing member 5 on the cover plate 22 makes the piercing direction clearer, which helps to reduce the problem of uneven insulation damage caused by piercing position deviation, and makes the piercing action easier to align with the metal part of the wire.

[0036] In some implementations, such as Figure 1 , Figure 2 As shown, the base 1 and the outer shell 21 are rotatably connected. It can be understood that the base 1 and the outer shell 21 can form an overall opening and closing structure by rotating the connection, so that the outer shell 21 can change angle around the rotation axis 6 of the base 1. This rotation method keeps the device in an open state during the initial placement of the wires, so that multiple wires can fall into multiple first slots 31 in sequence.

[0037] For example, the first end of the base 1 is provided with a first rotating sleeve 11, and the first end of the outer shell 21 is provided with a second rotating sleeve 211. A rotating shaft 6 passes through the first rotating sleeve 11 and the second rotating sleeve 211, so that the base 1 and the outer shell 21 can rotate relative to each other around the rotating shaft 6. The setting of the rotating shaft 6 makes the closing action of the outer shell 21 smoother and the alignment of the groove more stable, which to a certain extent helps the second groove 32 and the first groove 31 to correspond accurately in space. After the hole 3 is closed, it forms a more uniform constraint on the wire.

[0038] Furthermore, the second end of the base 1 is provided with a first cylindrical body 12, and the second end of the outer shell 21 is provided with a second cylindrical body 212. The fixing member 4 is provided in either the first cylindrical body 12 or the second cylindrical body 212. When the fixing member 4 is arranged in this position, it can be operated by the operator with one or both hands to mechanically fix the fit between the outer shell 21 and the base 1, so that the structure after rotation and closure maintains a stable shape and reduces the radial loosening of the wire in the hole 3.

[0039] It is understandable that the cooperation between the first cylinder 12 and the second cylinder 212 makes the arrangement of the fixing parts 4 more concentrated, without interfering with the use path of the piercing parts 5 or affecting the structural accuracy of the groove, thus making the entire shell 2 closing process present a smoother mechanical guiding effect. Overall, the rotating connection structure, through the cooperation of the rotating shaft 6, the rotating sleeve and the cylinder, makes the movement of the shell 21 from the open state to the closed state more natural, and makes the arrangement of the wires in the hole 3 more stable to a certain extent. This allows the operator to complete the opening, closing and fixing operations of the device in a more convenient way during the meter replacement process, and makes the wiring device play a positive role in terms of structural reliability and operational convenience.

[0040] In some implementations, combined with Figure 1 , Figure 2 and Figure 3 The fastener 4 includes a locking screw 41, which is located in one of the first cylinder 12 and the second cylinder 212. The other cylinder 12 and the second cylinder 212 are provided with a locking nut 7, and the locking screw 41 and the locking nut 7 are threadedly engaged.

[0041] For example, the locking screw 41 is located inside the second cylinder 212, and the locking nut 7 is located inside the first cylinder 12.

[0042] Understandably, when the locking screw 41 is screwed axially into the locking nut 7, the first cylinder 12 and the second cylinder 212 gradually come into contact in the axial direction, thus stabilizing the relative position of the outer shell 21 and the base 1 in the closed state. The threaded engagement structure has a controllable axial clamping force, allowing the operator to slightly adjust the locking force according to the clamping state of the wire in the hole 3 to obtain a more suitable clamping effect. This avoids excessive pressure on the wire insulation and also improves the stability of the wire in the hole 3 to a certain extent. Since the locking screw 41 and the locking nut 7 are located inside the two cylinders, the outer surface of the device remains relatively clean, and no protruding structures are generated near the opening and closing path of the shell 2, thus ensuring smooth rotation and closing of the outer shell 21. This locking structure forms a reusable mechanical fixing method through threaded engagement, allowing the wiring device to maintain good structural reliability and assembly consistency during multiple opening and closing operations.

[0043] In some implementations, such as Figure 3 As shown, a flange 221 is provided on one side of the cover plate 22, and a groove 213 is provided on the outer shell 21. The flange 221 and the groove 213 are in a limiting fit. It can be understood that the limiting fit between the flange 221 and the groove 213 enables the cover plate 22 to achieve a more defined positioning effect when installed on the outer shell 21. After the flange 221 is embedded in the groove 213, the range of movement of the cover plate 22 in the radial and circumferential directions is restricted, which helps to keep the position of the piercing part 5 more stable during the pressing process and improves the alignment of the piercing direction with the area of ​​the hole 3. At the same time, the fit between the flange 221 and the groove 213 forms a tighter contact between the cover plate 22 and the outer shell 21, which helps to improve the coordination of the overall structure during opening and closing.

[0044] In some implementations, such as Figure 3 As shown, the cover plate 22 and the outer shell 21 are connected by bolts.

[0045] For example, the cover plate 22 has a threaded groove, and the outer shell 21 has a through-hole along its thickness direction. When the outer shell 21 and the cover plate 22 are fitted together, the threaded groove and the mounting hole are axially connected. Further, the inner diameter of the mounting hole is larger than the inner diameter of the threaded groove, and a limiting protrusion is provided at one end of the mounting hole near the threaded groove. Thus, when connecting the cover plate 22 and the outer shell 21, the connecting bolt can be inserted from the end of the mounting hole away from the threaded groove, so that the bolt is threaded into the threaded groove, and the nut on the bolt is axially pressed against the limiting protrusion, thereby achieving the connection between the cover plate 22 and the outer shell 21.

[0046] In some implementations, combined with Figure 3 The outer shell 21 has a first channel 214 and the cover plate 22 has a second channel 222. The first end of the first channel 214 is connected to the hole body 3 and the second end of the first channel 214 is connected to the second channel 222. The piercing member 5 is movably inserted into the first channel 214 and the second channel 222.

[0047] For example, the first channel 214 penetrates the outer shell 21 along the thickness direction of the outer shell 21, and the first end of the first channel 214 is connected to the second groove 32; further, the second channel 222 penetrates the cover plate 22 along the thickness direction of the cover plate 22, and when the cover plate 22 is connected to the shell 2, the second channel 222 is axially connected to the first channel 214.

[0048] It is understandable that the piercing element 5 can move along the continuous channel to the direction of the hole 3 when it enters from the side of the cover plate 22. Since the piercing element 5 is movably inserted into the first channel 214 and the second channel 222, the lateral constraint on the piercing element 5 during axial movement is relatively stable, which suppresses the possibility of deviation in the piercing direction to a certain extent, making it easier for the piercing point to fall into a suitable area of ​​the wire insulation. The continuous structure between the first channel 214 and the second channel 222 allows the piercing element 5 to remain inside the channel when not pressed, preventing it from detaching from the channel and shaking during use, which is beneficial for maintaining good structural coordination of the overall device during field operation.

[0049] In some implementations, such as Figure 3 As shown, a threaded cylinder 8 is provided in the first channel 214, and the piercing member 5 includes a threaded section 51, which is threaded through the threaded cylinder 8.

[0050] For example, the outer ring wall of the threaded cylinder 8 and the inner ring wall of the first channel 214 are interference fit.

[0051] It is understandable that the threaded section 51 and the threaded cylinder 8 engage with each other, allowing the piercing piece 5 to move axially in a controllable manner under rotational drive. The threaded cylinder 8 is a cylindrical structure with internal threads, used to provide stability for guiding and limiting the piercing piece 5. The threaded section 51 refers to the threaded structure on the outer circumference of the piercing piece 5. The meshing of the two can improve the positioning accuracy of the piercing piece 5 in the channel to a certain extent, allowing the piercing piece 5 to maintain a controlled advancing state along the channel during the piercing action. Combined with the aforementioned channel structure, this is beneficial to improving the reliability and stability of the piercing action.

[0052] In some implementations, such as Figure 3 , Figure 4 As shown, the piercing element 5 also includes a piercing section 52, which is connected to the threaded section 51. The end of the piercing section 52 furthest from the threaded section 51 is pointed, used to generate a concentrated force on the insulation layer covering the conductor during the piercing action. It can be understood that the piercing section 52 refers to the slender structure at the front end of the threaded section 51. The pointed end reduces the initial contact area to a certain extent, making it easier for the piercing action to penetrate the insulation layer and continuously advance along the channel direction under the drive of the threaded section 51. The pointed end has geometrically converging characteristics, which helps improve the directionality of the piercing process, allowing the piercing element 5 to maintain a stable piercing path under the constraint of the guide structure, thereby obtaining more reliable conductive contact conditions.

[0053] In some implementations, combined with Figure 3 , Figure 4The puncture member 5 also includes a cylindrical section 53, which is connected to the end of the threaded section 51 away from the puncture section 52. A conductive slot 531 is provided in the cylindrical section 53, which is configured to allow an external plug to be inserted.

[0054] For example, the external plug is a banana plug, which includes a wire and two sub-plugs connected to the wire beam segment. The plug ends of the sub-plugs are rounded, and the shape of the conductive slot 531 is adapted to the shape of the sub-plugs. Thus, when L1 and L2 (or N1 and N2) are placed in two adjacent holes 3 respectively, L1 and L2 (or N1 and N2) can be short-circuited through the banana plug.

[0055] It is understandable that the cooperation between the cylindrical section 53 and the conductive slot 531 provides a certain guiding and restraining effect when the external plug is inserted, making the short-circuit operation more convenient. At the same time, it forms a stable electrical connection between the wires, which helps to reduce the electrical risks caused by the tangled wires or poor contact during the meter replacement operation without power interruption. It can also improve the efficiency and safety of the meter replacement operation to a certain extent.

[0056] In some implementations, such as Figure 4 As shown, a groove 532 is provided on the end wall of the cylindrical section 53 away from the puncture section 52. The groove 532 is configured to allow the insertion of an external auxiliary tool.

[0057] For example, the external auxiliary tool can be a flathead screwdriver, and the shape of the groove 532 is adapted to the end of the flathead screwdriver, so that the cylindrical section 53 can be rotated by inserting the end of the flathead screwdriver into the groove 532, so that the operator can easily apply torque by inserting the end of the screwdriver into the groove 532.

[0058] It is understandable that the groove 532, in conjunction with the screwdriver, provides a controlled rotation path to a certain extent, enabling the piercing element 5 to maintain stable directionality when rotating within the channel. This also assists the threaded section 51 in generating appropriate axial advance along the threaded cylinder 8, thereby piercing the wire insulation and forming electrical contact. This structure, by providing the groove 532 on the end wall of the cylindrical section 53 and adapting it to the auxiliary tool, allows operators better force transmission efficiency and tactile control when adjusting or rotating the piercing element 5. This helps reduce the possibility of the piercing element 5 shifting or becoming inaccurate during rotation, while also improving operational convenience and safety during meter replacement or wire connection. Overall, it contributes to improving the stability and operational efficiency of the wiring device in field use.

[0059] For example, the grooves 532 are disposed on both sides of the opening of the conductive slot 531 and remain in communication with the conductive slot 531, so that the grooves 532 form a lateral opening structure on the end wall of the cylindrical section 53 away from the piercing section 52. The position of the grooves 532 allows them to accommodate the insertion of the end of a flathead screwdriver. The engagement of the screwdriver with the grooves 532 applies torque to the cylindrical section 53, thereby improving the ease of rotation of the piercing member 5 to a certain extent. Since the grooves 532 are located on both sides of the opening of the conductive slot 531 and do not encroach on the central insertion channel of the conductive slot 531, the structure of the grooves 532 will not interfere with the normal insertion path of the banana plug along the central direction of the conductive slot 531 when rotation is not required. The functional characteristics of the conductive slot 531 remain stable during plug insertion. This structural configuration has a positive effect on the ease of manual adjustment of the piercing member 5 and the stability of the external plug insertion force.
