Description

Technical Field

[0001] This utility model belongs to the field of wire fixing technology, specifically relating to a live meter replacement wire fixing device to prevent miswiring. Background Technology

[0002] In power system operation and maintenance, electricity meters, as the core equipment for measuring users' electricity consumption, often experience problems such as excessive measurement errors and functional failures due to environmental factors or aging of their own components. Timely replacement is necessary to ensure measurement accuracy and the stability of power supply services. Currently, electricity meters are mostly installed in meter boxes, with high installation density and narrow operating space. To reduce the impact of power outages on users' electricity consumption, live meter replacement has become the mainstream operation mode. This requires temporary fixing and insulation protection of the incoming and outgoing wires of the electricity meter, while avoiding wiring errors to ensure the safety of equipment and personnel.

[0003] However, existing wire fixing tools for live meter replacement have shortcomings. Traditional methods rely on insulating tape or simple clips, which result in poor wire fixing stability, easy displacement, and lack of clear markings. When there are many wires on the meter terminal block, they need to be checked one by one, which can easily lead to incorrect wiring, causing metering failure and equipment burnout. At the same time, existing fixing tools mostly require manual operation by staff, which not only occupies operating space and distracts attention in the narrow space of the meter box, but also reduces work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a live meter replacement wire fixing device to prevent miswiring.

[0005] The technical solution adopted to solve the above technical problems is: a live meter replacement wire fixing device to prevent miswiring, including a wire fixing box, a number of pressing mechanisms are provided on the top plate of the wire fixing box, a number of plug-in ports for inserting wires are provided on one side of the wire fixing box, a number of labels are provided on the upper surface of the wire fixing box, and the position of the labels corresponds to the plug-in ports, and a number of magnets for fixing the wire fixing box are provided on the bottom surface of the wire fixing box;

[0006] The wire fixing box has several mounting cavities inside, each of which is equipped with a mounting plate. The mounting plate is equipped with a fixing mechanism for fixing the metal wire, and one end of the mounting plate is equipped with a snap-fit ​​mechanism for snapping the wire.

[0007] The inner walls on both sides of the mounting cavity are provided with linkage components for linking the fixing mechanism and the snap-fit ​​mechanism.

[0008] One end of the mounting plate is provided with a guide plate for bending the metal wire.

[0009] Furthermore, the pressing mechanism includes a sliding plate that is slidably inserted into the mounting cavity. A button is provided on the upper surface of the sliding plate, and the button passes through the top plate of the wire fixing box. Guide blocks are provided on both sides of the sliding plate. Guide grooves are provided on both sides of the inner wall of the mounting cavity, and the guide blocks are slidably inserted into the guide grooves.

[0010] Through the above technical solution, the pressing mechanism is mainly composed of a sliding plate, a button, and a guide block. The sliding cooperation between the guide block and the guide groove can accurately guide the movement direction of the sliding plate, ensuring that the sliding plate slides stably along a straight line when the button is pressed, avoiding deviation and jamming, thereby ensuring the smoothness and reliability of the pressing operation, and providing a stable triggering basis for subsequent mechanism linkage.

[0011] Furthermore, the fixing mechanism includes a first buckle and a second buckle mounted on the mounting plate. Both the first buckle and the second buckle are provided with U-shaped spring pieces. One end of each U-shaped spring piece is provided with a fixing frame. The upper ends of both sides of the fixing frame are provided with guide blocks. The guide blocks are slidably inserted into guide grooves. The lower ends of both sides of the fixing frame on the second buckle are provided with limit blocks.

[0012] Through the above technical solution, the first and second buckles of the fixing mechanism can clamp and fix the wire. The sliding fit between the second guide block and the guide groove can ensure that the fixing frame slides smoothly in the guide groove, making the opening and closing action of the buckles smoother. The first limit block provides a trigger point for the action of the linkage component, realizing the coordinated linkage between the fixing mechanism and other components, and improving the integration and functionality of the overall structure.

[0013] Furthermore, the snap-fit ​​mechanism includes a fixing groove on the upper surface of the mounting plate, a snap-fit ​​spring is inserted into the fixing groove, and limit blocks are provided on both sides of one bottom end of the snap-fit ​​spring.

[0014] Through the above technical solution, the snap-fit ​​spring of the snap-fit ​​mechanism can snap-fit ​​and fix the inserted part. The second limiting block is located above one end of the swing lever and can cooperate with the swing lever to realize the linkage control of the snap-fit ​​mechanism. The locking and unlocking actions of the snap-fit ​​can be triggered by the pressing mechanism, which improves the convenience of operation.

[0015] Furthermore, the linkage component includes swing levers disposed on both sides of the mounting cavity, a fixed shaft hole is provided in the middle of the swing lever, a rotating shaft is inserted into the fixed shaft hole, and one end of the rotating shaft is welded to the side wall of the mounting cavity.

[0016] Through the above technical solution, the swing lever of the linkage component can achieve stable swinging with the rotating shaft as the fulcrum. The cooperation between the fixed shaft hole and the rotating shaft ensures the rotation accuracy of the swing lever, so that the swing lever can accurately act on the limit block one and limit block two when triggered, realizing the linkage operation of the fixing mechanism and the locking mechanism, and ensuring the synchronization and accuracy of the actions of each component.

[0017] Furthermore, one end of the swing lever is located below the second limiting block, and the other end of the swing lever is located below the first limiting block.

[0018] With the above technical solution, the two ends of the swing lever are respectively engaged with limit block two and limit block one. When the pressing mechanism triggers the swing lever to swing, it can simultaneously apply force to limit block two of the locking mechanism and limit block one of the fixing mechanism, so as to realize the unlocking of the locking mechanism and the opening and closing of the fixing mechanism are carried out synchronously, simplifying the operation process and improving the linkage efficiency of the overall mechanism.

[0019] Furthermore, the number of the labels corresponds to the number of the plug ports, with three plug ports forming a group, and the plug ports in different groups having different colors.

[0020] The above technical solution uses a numbering system that corresponds to the number of plug ports, making it easy to quickly identify the function of each plug port. Different groups of plug ports are distinguished by different colors, which can intuitively distinguish line interfaces with different functions or voltage levels, avoid wiring errors, improve the efficiency and accuracy of wiring operations, and enhance the standardization of line management.

[0021] The beneficial effects of this utility model are as follows: (1) By setting a fixing mechanism and a snap-fit ​​mechanism, the fixing mechanism can form a stable clamp on the metal wire by the cooperation of snap-fit ​​one, snap-fit ​​two and U-shaped spring piece, and avoid the wire from shifting during operation. The snap-fit ​​spring piece of the snap-fit ​​mechanism further enhances the wire fixing effect and prevents it from falling off. At the same time, the guide plate can bend the wire reasonably to avoid messy contact of the exposed part of the wire and further enhance the wire's firmness to prevent it from falling off; (2) By setting a magnet piece, the magnet piece at the bottom of the wire fixing box can quickly adsorb the device onto the power meter, eliminating the need for staff to operate it by hand, completely freeing their hands. This is especially useful in situations where the power meter is densely packed and the operation is difficult. In the narrow meter box, it can greatly reduce space occupation and reduce operation interference. On the other hand, the pressing mechanism, in conjunction with the linkage component, fixing mechanism and snap-fit ​​mechanism, can complete the quick fixing and removal of the wire by simply pressing the button, simplifying the operation process of the traditional complex fixing structure; (3) By setting the number, the design of “plug-in port-number” corresponds one by one, and the three plug-in ports are a group and are distinguished by different colors, which can enable the staff to quickly identify the meter terminal corresponding to the wire, without having to check the polarity and terminal one by one, reducing the risk of incorrect wiring from the source, preventing the secondary circuit from short circuit or open circuit due to wiring error, and ensuring the stable operation of the metering equipment and the safety of electricity use.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figures 1-5As shown in the figure, a live meter replacement wire fixing device for preventing miswiring in this embodiment includes a wire fixing box 1. The wire fixing box 1 is made of flame-retardant ABS engineering plastic, which has the characteristics of insulation and high temperature resistance. The wire fixing box 1 is divided into several independent mounting cavities 101 by longitudinal partitions. The number of mounting cavities 101 matches the number of meter terminals. A mounting plate 102 is horizontally fixed in each mounting cavity 101. The mounting plate 102 provides a stable mounting base for the fixing mechanism 4 and the snap-fit ​​mechanism 5. Several insertion ports 3 are provided on one side of the wire fixing box 1, corresponding to the positions of the mounting cavities 101. The insertion ports 3 are circular holes. The upper surface of the wire fixing box 1 is marked with corresponding insertion ports 3. The top of each terminal is laser-engraved with the number 8, which is arranged sequentially using Arabic numerals. Operators can quickly identify the connection relationship between the wire and the meter terminal by using the number 8, avoiding wiring misalignment. The three plug ports 3 are grouped together, and the edges of the plug ports 3 in different groups are marked with different colors of injection molding process, such as red for the first group, blue for the second group, and yellow for the third group, to further enhance group identification and structurally eliminate the problem of incorrect wiring across groups. The bottom surface of the wire fixing box 1 is provided with several magnetic pieces 9 for fixing the wire fixing box 1. The magnetic pieces 9 can quickly attract and fix the wire fixing box 1 to the metal inner wall of the meter box without drilling, which simplifies the operation and avoids damage to the meter box.

[0030] Regarding the pressing mechanism 2, such as Figures 3-4 As shown, on the top plate of the wire fixing box 1, a pressing mechanism 2 is installed at the position corresponding to each mounting cavity 101. The pressing mechanism 2 includes a sliding plate 202 that is slidably inserted into the mounting cavity 101. The size of the sliding plate 202 is adapted to the cross-section of the mounting cavity 101 and can slide up and down along the mounting cavity 101. A button 201 is integrally formed at the center of the upper surface of the sliding plate 202. The button 201 has a cylindrical structure and penetrates through the top plate of the wire fixing box 1 for easy pressing by the operator. Guide blocks 203 are provided on both sides of the sliding plate 202. Guide grooves 204 are opened on both sides of the inner wall of the mounting cavity 101. The guide blocks 203 are slidably inserted into the guide grooves 204, which can limit the movement direction of the sliding plate 202 and prevent it from shifting or tilting during the pressing process, ensuring stable movement.

[0031] Regarding fixed mechanism 4, such as Figures 3-5As shown, the mounting plate 102 is provided with a fixing mechanism 4 for fixing metal wires, which is used to firmly fix the inserted wires and prevent them from loosening. The fixing mechanism 4 includes a first buckle 401 and a second buckle 402 provided on the mounting plate 102. Both are made of elastic metal sheet material and have good deformation and resilience. Both the first buckle 401 and the second buckle 402 are provided with U-shaped spring pieces 403. The U-shaped spring pieces 403 are made of elastic metal sheet material and have good deformation and resilience. A fixing frame 4 is provided at one end of each U-shaped spring piece 403. 04. The fixed frame 404 is a rectangular metal frame used to fix the wire. The upper ends of both sides of the fixed frame 404 are provided with guide blocks 2 406. The guide blocks 2 406 have the same structure as the guide blocks 1 203 and are slidably inserted into the guide grooves 204 of the mounting cavity 101 to ensure that the fixed frame 404 moves up and down synchronously with the sliding plate 202. The lower ends of both sides of the fixed frame 404 on the buckle 2 402 are provided with limit blocks 1 405. The limit blocks 1 405 are cylindrical metal blocks used to cooperate with the linkage component 6 to transmit linkage actions.

[0032] Regarding card receiving mechanism 5, such as Figures 3-5 As shown, the mounting plate 102 is provided with a snap-fit ​​mechanism 5 at one end near the insertion port 3, which is used to limit the insertion end of the wire. The snap-fit ​​mechanism 5 includes a fixing groove 502 on the upper surface of the mounting plate 102. The fixing groove 502 is a rectangular groove, which is the installation position for the snap-fit ​​spring 501. The snap-fit ​​spring 501 is inserted into the fixing groove 502. The snap-fit ​​spring 501 is made of elastic metal sheet and has a "V" shaped structure. After the wire is inserted, the wire can be elastically clamped. Limiting blocks 503 are provided on both sides of the bottom end of the snap-fit ​​spring 501. The limiting blocks 503 are cylindrical metal blocks that extend out of the outer walls of both sides of the snap-fit ​​spring 501 and are used to contact the linkage component 6 to receive the linkage action signal.

[0033] Regarding the linkage component 6, such as Figures 3-5As shown, linkage components 6 are provided on both inner walls of the mounting cavity 101 for linking the fixing mechanism 4 and the locking mechanism 5. These components enable the linkage of the pressing mechanism 2, the fixing mechanism 4, and the locking mechanism 5, ensuring synchronized operation. The linkage components 6 include swing levers 601 on both sides of the mounting cavity 101. The swing levers 601 are made of stainless steel and have a fixing shaft hole 602 in the middle. A rotating shaft 603 is inserted into the fixing shaft hole 602. One end of the rotating shaft 603 is welded to the side wall of the mounting cavity 101, allowing the swing levers 601 to rotate freely around the rotating shaft 603, forming a lever structure. One end of the swing lever 601 is located below the limiting block 503, and the other end of the swing lever 601... Located below the first limiting block 405, when the sliding plate 202 of the pressing mechanism 2 moves downward, it will push the fixed frame 404 downward. The fixed frame 404 presses down on the upper end of the swing lever 601 through the first limiting block 405, causing the swing lever 601 to rotate around the rotating shaft 603. Its lower end rises and pushes up the second limiting block 503, thereby causing the snap-fit ​​spring 501 to open upward, making it easier to insert the wire. After releasing the button 201, the sliding plate 202 returns to its original position, the fixed frame 404 moves upward, the swing lever 601 loses its downward pressure, and the snap-fit ​​spring 501 returns to its original position and clamps the wire under its own elasticity. At the same time, the U-shaped spring 403 of the fixing mechanism 4 causes the first snap-fit ​​401 and the second snap-fit ​​402 to close, completing the double fixing of the wire.

[0034] Working principle: Align the magnet 9 at the bottom of the wire fixing box 1 with the power meter dial, and fix the device to the dial by magnetic attraction. Then press the actuation mechanism 2. According to the circuit function corresponding to the power meter wire, refer to the corresponding number 8 on the upper surface of the wire fixing box 1 and the corresponding plug-in port 3, and combine the distinction rule of "three sets of plug-in ports 3 with different colors", insert the wire into the mounting cavity 101 from the corresponding plug-in port 3. After the wire is fully inserted, the U-shaped spring pieces 403 of the first buckle 401 and the second buckle 402 in the fixing mechanism 4 on the mounting plate 102 automatically rebound, forming a clamp and fixation for the wire. At the same time, the spring piece 501 of the clamping mechanism 5 rebounds to limit the wire. The wire is detached, completing the double fixation of the wire. At the same time, during the insertion process, the wire is naturally bent by the guide plate 7, further enhancing the wire's ability to prevent detachment. After the meter is replaced, press the pressing mechanism 2 on the top plate of the wire fixing box 1. The button 201 drives the sliding plate 202 to slide down along the guide groove 204, causing the fixing frame 404 and the U-shaped spring 403 to retract. At the same time, the first limit block 405 presses down the swing lever 601, triggering the swing lever 601 of the linkage component 6 to rotate around the rotating shaft 603. One end of the swing lever 601 pushes up the second limit block 503, causing the snap-fit ​​spring 501 to retract, releasing the wire fixation. Then the wire is taken out from the plug-in port 3 and connected to the new meter.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
