Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to a metering box with concealed wiring. Background Technology

[0002] In the field of electrical equipment technology, metering boxes, as important devices, play a crucial role in the metering and monitoring of power systems. With the continuous development of the power industry, the functional and performance requirements for metering boxes are also increasing. A well-designed and fully functional metering box can improve the operating efficiency of the power system, ensure the normal operation of power equipment, and also contribute to enhancing the safety and reliability of the power system. In practical applications, metering boxes need to meet various requirements, such as facilitating wiring and cable management, ensuring the orderly arrangement of cables, and possessing good sealing performance to prevent external moisture, dust, and other contaminants from entering the box and damaging electrical components.

[0003] In related technologies, the methods used to solve wiring and sealing problems are often quite fragmented. For wiring, simply leaving some space inside the box for cables to pass through freely, without any dedicated organization or guidance, leads to cables easily becoming tangled and messy, affecting not only aesthetics but also increasing the difficulty of later maintenance and repair. Regarding sealing, ordinary sealing materials may be used to seal the openings of the box, but this method often only provides a limited solution, failing to effectively seal areas where cables pass through and unable to completely prevent the intrusion of moisture and dust. Furthermore, traditional metering boxes lack effective coordination between their various functional modules, requiring users to perform multiple steps separately during wiring and sealing operations, resulting in a cumbersome and inefficient process.

[0004] However, due to the dispersed functional modules, wiring, cable management, and sealing operations cannot be organically integrated, resulting in cumbersome procedures that require users to spend a significant amount of time and effort to complete. Furthermore, the lack of effective cable management and concealment not only affects the tidiness of the box's interior but may also lead to signal interference due to cable clutter. In addition, inadequate sealing measures allow external moisture and dust to easily enter the box, damaging electrical components, reducing the metering box's lifespan and reliability, and failing to meet the requirements of modern power systems for efficient and reliable metering box operation. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a metering box with concealed wiring function.

[0006] A metering box with concealed wiring, comprising a box body, and further comprising: A partition is installed inside the box, and at least one mounting port is provided on the partition; A cover assembly corresponding to the mounting port is provided, the cover assembly including a cover body that can slide relative to the partition to open or close the mounting port; The cable sorting assembly is located on the side of the partition facing away from the cover body and corresponds to the position of the mounting port. When the cover body is in the open position, the cable sorting assembly is exposed to guide the cable. When the cover body is in the closed position, the cable sorting assembly and the cable guided by it are contained in the mounting port closed by the cover body. A cable sealing assembly, disposed on the partition and corresponding to the mounting port, is used to seal the cable passing through the cable combing assembly when the cover body is in the closed position.

[0007] By adopting the above technical solution, the operation of the three major functions of wiring, cable management and sealing is unified. Users only need to operate the cover plate to complete the entire process from wiring to sealing, which greatly simplifies the operation steps and solves the problems of scattered functional modules and cumbersome operation of traditional metering boxes.

[0008] Optionally, the cover assembly also includes at least two guide rails fixed to the surface of the partition, and a slider slidably connected to the guide rails, with the cover body fixedly connected to the slider; the guide rails are provided with a limiting structure to limit the opening and closing positions of the cover body.

[0009] By adopting the above technical solution, the cover plate assembly, cable combing assembly, and cable sealing assembly are integrated onto a partition with an installation port, achieving unified operation of the three major functions of wiring, cable management, and sealing, and simplifying the operation steps. The sliding cooperation between the guide rail and the slider ensures the linearity, stability, and high repeatability of the cover plate's movement trajectory. The limiting structure allows the cover plate to stop precisely and reliably at the preset "fully open" and "fully closed" positions, avoiding misalignment of the combing assembly or sealing failure due to uncertain position, thus improving the certainty and reliability of the entire system operation.

[0010] Optionally, the limiting structure includes a limiting block fixed to one end of the guide rail and a limiting horizontal plate fixed to the middle of the guide rail. The cover plate body is provided with an abutting block that can abut against the limiting block or the limiting horizontal plate. The abutting surfaces of the cover plate body and the limiting horizontal plate are provided with magnetic elements that attract each other.

[0011] By adopting the above technical solution, the limiting and fixing mechanism is refined. The limiting block and the limiting cross plate provide clear mechanical hard limits to ensure accurate end of the stroke. The magnetic component provides additional adsorption and holding force when the cover is closed, so that the cover stays stably and resists slight vibration or accidental touch. At the same time, it provides users with clear tactile feedback of "closed in place", which improves the human-computer interaction experience and the initial fixing effect.

[0012] Optionally, it also includes a resilient latch for locking the cover body in the closed position; the resilient latch includes a spring hinged to the partition and bent toward the axis of the mounting opening, the free end of the spring forming a retaining plate; when a pressure perpendicular to the partition is applied to the cover body in the closed position to compress an elastic element and it continues to move, the side of the cover body passes over the retaining plate, and after the pressure is removed, the cover body abuts against the side of the retaining plate opposite to the mounting opening under the restoring force of the elastic element.

[0013] By adopting the above technical solution, the cover plate body, guide rail, slider, limit block, limit cross plate, abutment block, and magnetic components are combined to achieve unified operation of the three major functions of wiring, cable management, and sealing. This ensures the linearity, stability, and high repeatability of the cover plate body's movement, enabling it to stop accurately and reliably at the preset position. It provides clear mechanical hard limit and adsorption holding force. The elastic buckle provides a more robust mechanical locking on the basis of the cover plate's mechanical closure. The "press-lock" operation method is intuitive and simple. After locking, it can effectively prevent the cover plate from being accidentally opened under external impact or vibration, significantly enhancing the safety and stability of the equipment in the operating environment. It is especially suitable for occasions that require long-term reliable locking.

[0014] Optionally, the elastic element is a helical spring sleeved on the guide rod connecting the slider and the cover plate body.

[0015] By adopting the above technical solution, a helical spring sleeved on the guide rod is used as an elastic element to provide a uniform and vertical reset force for the cover plate body, ensuring stable contact with the buckle plate and guaranteeing the smoothness and reliability of the locking and unlocking actions.

[0016] Optionally, the cable combing assembly includes a first combing block that is fixedly disposed, and at least one first cable groove is provided on the first combing block; a second combing block is fixedly disposed on the cover body, and a second cable groove corresponding to the first cable groove is provided on the second combing block; when the cover body is in the closed position, the second combing block and the first combing block are inserted and cooperated, so that the first cable groove and the second cable groove together form a complete cable channel.

[0017] By adopting the above technical solution, the cover plate assembly, cable combing assembly, and cable sealing assembly are integrated into a partition with an installation port, realizing unified wiring, cable management, and sealing operations. Users can complete the entire process by operating the cover plate. The first and second combing blocks can be separated and combined. When the cover is opened, the open wiring slot of the first combing block facilitates the quick insertion and adjustment of cables. When the cover is closed, the second combing block and the first combing block form a closed and neat ring-shaped cable channel, completely hiding the cables and playing a role in combing, positioning, and protecting the cables.

[0018] Optionally, the cable sealing assembly includes at least one sealing block movably disposed on the partition, the sealing block having a clamping surface adapted to the shape of the outer wall of the cable; the sealing block is connected to a drive member that drives it to provide a preload in the direction of the cable.

[0019] By adopting the above technical solution, the cover plate assembly, cable combing assembly, and cable sealing assembly are integrated into a partition with an installation port, realizing the unified operation of the three major functions of wiring, cable management, and sealing, and simplifying the operation steps; the first and second combing blocks can be separated and combined. When the cover is opened, the first combing block facilitates the insertion and adjustment of cables, and when the cover is closed, it forms a closed cable channel with the second combing block to hide and protect the cables; the movable sealing block, together with the driving component, can closely fit the outer wall of different cables, dynamically apply sealing force, fill gaps, achieve excellent radial sealing effect, and block the penetration path of water vapor and dust.

[0020] Optionally, the driving component is a bimetallic strip, with one end fixed and the other end connected to a sealing block. This provides an initial preload force to press the sealing block against the cable and can adjust the preload force according to temperature changes.

[0021] By adopting the above technical solution, using a bimetallic strip as a driving component, it can provide the initial preload force to press the sealing block against the cable, achieving radial sealing of the cable and blocking the penetration path of water vapor and dust along the cable surface; it can also adapt to changes in cable temperature by generating adaptive deformation, dynamically adjusting the clamping force, compensating for the thermal expansion of the cable, preventing excessive compression from damaging the cable insulation layer, and ensuring long-term sealing reliability, safety, and adaptability to complex working conditions; and with the design of the movable sealing block and driving component, it can closely fit the outer wall of cables of different diameters or with slight deformation, filling the irregular gaps between the cable and the comb block.

[0022] Optionally, an annular plate with an opening is fixed to the inner wall of the enclosure, and a sealing ring is provided at the opening of the annular plate; one side of the partition is hinged to the inner wall of the enclosure, and the other side is fixed to the inner wall of the enclosure through a detachable connector, so that when the partition is installed in place, its plate surface presses against the sealing ring, thereby dividing the interior of the enclosure into a component compartment and a wiring compartment.

[0023] By adopting the above technical solution, a macroscopic and large-area sealed separation between the component room and the wiring room is achieved, preventing moisture and dust from the wiring room from entering the core component room on a large scale, ensuring the operating environment of electrical components. In addition, the hinged design allows the partition to be opened like a door, which facilitates large-scale installation, maintenance or cleaning of the inside of the enclosure, improving the maintainability of the equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating the cover plate assembly, cable management assembly, and cable sealing assembly onto a partition with an installation port, the operation of the three major functions of wiring, cable management, and sealing is unified, simplifying the operation steps and solving the problems of scattered functional modules and cumbersome operation in traditional metering boxes; 2. The cover plate assembly ensures the linearity, stability and high repeatability of the cover plate body movement through the sliding cooperation of the guide rail and the slider and the limiting structure, so that it can stop precisely at the preset position, thereby improving the certainty and reliability of the system operation. 3. The first and second combing blocks of the cable combing component can be separated and combined. Opening the cover facilitates the quick insertion and adjustment of cables, while closing the cover forms a closed ring cable channel, hiding the cables and playing a role in combing, positioning and protecting the cables to prevent them from becoming loose or tangled.

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0028] A metering box with concealed wiring, refer to Figure 1The system includes a housing 1, a partition 2 mounted on the housing 1, multiple cover assemblies 3 mounted on the partition 2, multiple cable management assemblies 4 mounted on the partition 2, and multiple cable sealing assemblies 5 mounted on the partition 2. Each cover assembly 3 corresponds to one cable management assembly 4 and one cable sealing assembly 5. The partition 2 has an opening, which is opened or closed by a cover plate inside the cover assembly 3. The cable management assembly 4 is exposed when the cover body 303 is in the open position, and is used to guide cables. When the cover body 303 is in the closed position, the cable management assembly 4 and the guided cables are housed in the installation compartment 9, and the cables pass through the axial through-hole of the cable sealing unit into the housing 1. The lifting and lowering movement of the cover assembly 3 controls the exposure and concealment of the cable management assembly 4, and works in conjunction with the inner cable sealing assembly 5 to achieve integrated operation of "opening the cover for wiring, closing the cover for concealment, and internal sealing".

[0029] Reference Figure 1 , Figure 2 An annular plate 6 is fixedly connected to the inner wall of the enclosure 1. The annular plate 6 has an opening for cable routing, and a sealing ring 7 is fixedly connected to one side of the annular plate 6. A hinge plate is fixed to one side of the partition 2 with screws, and the partition 2 is hinged to the surface of the annular plate 6 via the hinge plate, allowing the partition 2 to rotate along the hinge axis to close and open the opening of the annular plate 6. Additionally, a flange 8 is integrally formed on the periphery of the side of the partition 2 opposite to the hinge plate, and the partition 2 is fixed to the surface of the annular plate 6 with screws through the flange 8. After the partition 2 is installed in place, one side of the partition 2 abuts against the sealing ring 7 of the annular plate 6, thereby dividing the enclosure 1 into a component compartment and a cable routing compartment.

[0030] On the side of the partition 2 facing the back panel of the enclosure 1, a plurality of mounting compartments 9 corresponding to the number of cover assembly 3 are integrally formed. The mounting openings of the mounting compartments 9 are located on the side facing the enclosure door. The mounting compartments 9 are provided with through holes for cable routing. External cables can first extend into the cable routing chamber of the enclosure 1, and then extend into the corresponding mounting compartment 9 through the through holes.

[0031] Reference Figure 2 , Figure 3 , Figure 4A cover assembly 3 is installed at a corresponding mounting compartment 9. Each cover assembly 3 includes two guide rails 301 mounted on the surface of a partition 2, sliders 302 slidably mounted on the guide rails 301, and a cover body 303 fixedly connected to the sliders 302. The two guide rails 301 are fixed to the side of the partition 2 facing the opening of the housing 1 by screws, and are arranged on both sides of the mounting opening of the corresponding mounting compartment 9, with the mounting opening of the mounting compartment 9 located between the two guide rails 301. Two sliders 302 are slidably mounted on each guide rail 301 to improve the sliding stability of the cover body 303. The cover body 303 is fixedly connected to the sliders 302 via connecting rods.

[0032] Reference Figure 4 , Figure 5 An abutment block 304 is integrally formed on the top surface of the cover body 303 near the box body 1. Additionally, a limit block 305 is fixedly connected to the side of the guide rail 301 near the bottom surface of the box body 1, and a limit plate 306 is fixedly connected to the middle of the guide rail 301. When the abutment block 304 abuts against the limit block 305, the cover body 303 is located below the mounting opening, and is in the open position. When the abutment block 304 abuts against the limit plate 306, the cover body 303 is located at the mounting opening and closes it, and is in the closed position. A magnetic strip 307 is fixed to both the side of the limit plate 306 facing the cover body 303 and the side of the cover body 303 facing the limit plate 306, allowing the cover body 303 and the limit plate 306 to be magnetically connected via the magnetic strips 307. In addition, a mounting base for installing an electricity meter can be slidably connected to the guide rail 301. The mounting base is located on the side of the limiting plate 306 away from the cover plate body 303, thereby realizing a quick connection between the mounting base and the electricity meter.

[0033] Each slider 302 is fixedly connected to a guide rod 308, which passes through the cover plate body 303, and the end of the guide rod 308 is connected to a limit ring 309 by a thread. In addition, a helical spring 310 is sleeved on the part of the guide rod 308 between the slider 302 and the cover plate body 303, which is used to provide a preload force to the cover plate body 303 to move it away from the partition 2.

[0034] Four springs 311 are hinged around the mounting opening of the partition 2, serving as elastic latches. Each spring 311 is slightly bent towards the axis of the mounting opening. A retaining plate 312 is integrally formed at the end of each spring 311 away from the partition 2, and a mounting plate is integrally formed at the other end of each spring 311. One side of the mounting plate is hinged to the surface of the partition 2 via a hinge piece, and the other side is fixed to the surface of the partition 2 via a return spring 313. Additionally, a notch is provided on the cover body 303 to mate with the retaining plate 312. When the cover body 303 is in the closed position, applying pressure perpendicular to the partition 2 to the cover body 303 causes the coil spring 310 to deform and compress, allowing the cover body 303 to slide closer to the partition 2. After the cover plate body 303 slides, it first presses the spring 311 and the retaining plate 312, causing the end of the spring 311 to bend downwards. When the side of the cover plate body 303 passes the retaining plate 312, the spring 311 returns to its original position under its own elastic preload. After the pressure applied to the cover plate body 303 is removed, the cover plate body 303 is locked in place by the spring force of the coil spring 310 and the spring 311 and retaining plate 312, thereby locking the cover plate body 303 in the closed state.

[0035] Reference Figure 1 , Figure 4 , Figure 5 The cable combing assembly 4 includes a first combing block 401 slidably inserted into the inner wall of the mounting compartment 9. The first combing block 401 has three first cable grooves, each with its opening facing the top of the housing 1. Additionally, the cover plate body 303 has three U-shaped grooves. A second combing block 402 with a U-shaped cross-section is fixedly connected to the cover plate body 303 within each U-shaped groove. The second combing block 402 has second cable grooves, the position and opening orientation of which correspond to the first cable grooves. When the cover plate body 303 is in the closed state and locked position, the second combing block 402 is inserted into the first cable groove, causing it to abut against the inner wall of the first cable groove.

[0036] The cable sealing assembly 5 includes three adjustment slots on the limiting cross plate 306, each corresponding to a position on the second comb block 402. A sealing block 501 is inserted into each adjustment slot. One end of the sealing block 501 is fixed to the inner wall of the adjustment slot via a bimetallic strip 502, and the other end has a clamping surface adapted to the shape of the cable's outer wall. When the cover body 303 is in the locked closed position, the sealing block 501 extends into the second comb block 402 and, in conjunction with the second comb block 402, clamps the cable. Simultaneously, after the sealing block 501 is in place, it can compress the bimetallic strip 502, which provides an initial pre-tightening force towards the bottom of the housing 1 to ensure the cable's sealing performance and prevent external moisture from entering the component chamber from the cable routing chamber. Furthermore, the degree of thermal bending deformation of the bimetallic strip 502 matches the degree of thermal expansion of the cable.

[0037] The implementation principle of this application embodiment is as follows: The core of this solution lies in the simultaneous control of the exposure / concealment of the cable wiring space and the sealing of the cable channel through the single linear sliding action of the cover plate body 303, thereby achieving integrated operation.

[0038] During the wiring stage, the cover plate body 303 is slid down along the guide rail 301 to the open position (the abutment block 304 contacts the limiting block 305). At this time, the installation compartment 9 is fully exposed, and the operator can pass the cable through the through hole at the rear of the installation compartment 9 from the cable routing room of the box 1, and put it into the first cable groove of the exposed first comb block 401 for initial guidance and positioning. The operation space is ample and intuitive.

[0039] When the wiring is completed and the enclosure 1 needs to be closed, the cover plate body 303 is pushed up to the closed position (the abutment block 304 and the limiting horizontal plate 306 are fixed by magnetic strip 307). During this process, the second combing block 402 fixed on the cover plate body 303 moves upward and is precisely inserted into the first cable groove of the first combing block 401. The two work together to constrain the originally open cables within the closed channel formed by the first cable groove and the second cable groove. The cables are completely stored in the mounting compartment 9 behind the cover plate body 303, resulting in a neat appearance.

[0040] Once the cover plate body 303 reaches the closed position, it can be further pressed to lock it in place by the elastically snapped latch plate 312. At this time, the sealing block 501 located within the limiting cross plate 306, under the initial pre-tightening force provided by the bimetallic strip 502, has its arc groove tightly pressed into the cable inside the second comb block 402, forming an effective radial seal and preventing moisture from entering the component chamber along the cable surface. The bimetallic strip 502 can adapt to changes in cable temperature (caused by current load) and dynamically adjust the clamping force to ensure long-term sealing reliability.

[0041] Furthermore, the entire partition 2 is sealed by the compression of its periphery with the annular plate 6 and the sealing ring 7, ensuring a static seal between the component compartment and the wiring compartment. Ultimately, through two simple actions of "opening the cover" and "closing the cover," the entire process from wiring guidance to cable concealment and internal and external sealing is completed efficiently and reliably.
