Description

Technical Field

[0001] This utility model relates to the field of wiring support technology, specifically to a splicable wiring support for the internal wiring of a power metering box. Background Technology

[0002] The power metering box is a key component of the power metering and management system. Together with the internal wiring support, it forms a safe, reliable, and standardized metering unit. In this system, the metering box, as the whole and the outer shell, provides the structural body and physical space, and undertakes the functions of final safety protection, external support, and overall enclosure. The wiring support, as a part and the skeleton, is a functional structure integrated into the box. Its core function is to support, organize, and fix all the cables and electrical components inside the box, ensuring orderly wiring, safe electrical clearance, and easy maintenance. Currently, the mainstream design in this field is to integrate the wiring bracket with the matching metering box for integrated production; that is, to design and manufacture a dedicated wiring bracket for a specific model and size metering box. While this approach ensures a certain degree of initial installation compatibility, it has gradually revealed the following inherent defects in actual application, maintenance, and supply chain management: Because the wiring brackets are custom-made for specific metering boxes, their structure, size, and installation locations are fixed. This means that the same bracket cannot be flexibly adapted to metering boxes of different specifications, manufacturers, or application scenarios. When users or construction units have multiple models of metering boxes, they need to stock multiple corresponding brackets, which increases the cost and complexity of material management. In some emergency situations, construction personnel may even have to resort to non-standard modification methods such as on-site cutting and welding for emergency handling. This approach is not only inefficient but also damages the structural integrity and safety of the brackets. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a modular wiring bracket for the internal wiring of a power metering box, thus solving the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: The internal wiring support of the modular power metering box includes: a crossbeam, a splicing connector fixedly installed on one side of the crossbeam, and a wire harness assembly assembled on the back of the crossbeam; The connector has a splicing cavity on its inner side, and an installation port is provided at the bottom of each splicing cavity. The installation port and the interior of the splicing cavity are equipped with a snap-fit ​​component. The crossbeam is connected to the snap-fit ​​component through the splicing connector. The wire harness assembly includes a hollow wire clamping plate, a secondary clamping plate, a partition plate, and a threaded rod. The hollow wire clamping plate is fixedly installed on the back of the crossbeam. The secondary clamping plate is slidably connected to the crossbeam on one side of the hollow wire clamping plate. A threaded rod is installed through the hollow wire clamping plate and the secondary clamping plate. The threaded rod is threadedly connected to the secondary clamping plate. Several partition plates are slidably connected to the inner side of the secondary clamping plate. The snap-fit ​​assembly includes snap-fit ​​connectors, with snap-fit ​​connectors extending into the splicing cavity elastically mounted at the bottom of the mounting port, and the snap-fit ​​connectors snap-fit ​​into the splicing connectors respectively.

[0005] Furthermore, the outer side of the connector is provided with a mating interface, and an extended telescopic square rod is installed inside the mating interface. The front of the connector is provided with a guide port, and a fastening knob that passes through the guide port is threadedly installed on the telescopic square rod.

[0006] Furthermore, the snap-fit ​​assembly also includes a pull plate, a spring, and a guide rod. The bottom of the snap-fit ​​connector is fixedly connected to a guide rod extending into the mounting opening, and a spring is fitted onto the guide rod inside the mounting opening. The bottom end of the guide rod is fixedly mounted with a pull plate, and friction textures are provided on both sides of the pull plate.

[0007] Furthermore, each of the splicing joints has three sets of locking ports at its bottom, and the locking ports are mated and cooperate with the locking connector.

[0008] Furthermore, a mounting base is fixedly installed on the outer end of the telescopic square rod, and mounting feet for installation are fixedly installed on the mounting base.

[0009] Furthermore, the wire harness assembly also includes a second fastening knob and a guide block. A second guide opening is provided on the sub-clamp plate, and several guide blocks are slidably installed in the second guide opening. A partition plate is installed on one side of the guide block, and a second fastening knob that is threadedly connected to the guide block is assembled on one side of the sub-clamp plate.

[0010] This utility model provides a modular wiring bracket for the internal wiring of a power metering box. Compared with the prior art, it has the following advantages: 1. Using crossbeams as the basic unit, the splicing joints and cavities achieve the following effects: Installers can connect multiple crossbeams end to end by simply inserting and splicing them according to the actual size of the metering box, thus extending the length of the support indefinitely. This solves the problem of traditional supports requiring customized lengths or on-site cutting, and realizes the flexibility of assembling non-standard sizes from standard parts. Modular splicing is achieved through snap-fit ​​components. During the process of inserting the splicing connector into the splicing cavity, the snap-fit ​​connector is automatically pressed down and automatically pops up and locks after being aligned with the slot. The whole process does not require any tools, which greatly improves the installation efficiency. 3. The hollow cable clamp and the secondary clamp form a main cable channel. Its fundamental effect is to gather multiple scattered cables into a neat bundle, completely avoiding the spider web-like mess of wiring inside the box, and improving safety and aesthetics.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Example To address the technical problems in the background section, the following modular wiring support for power metering boxes is provided: Combination Figures 1-5 As shown, the splicable power metering box internal wiring bracket provided by this utility model has a crossbeam 200, a splicing joint 700 fixedly installed on one side of the crossbeam 200, and a wire harness assembly 600 assembled on the back of the crossbeam 200. The connector 500 has a splicing cavity 504 on its inner side. The bottom of the splicing cavity 504 is provided with an installation port 505. The installation port 505 and the interior of the splicing cavity 504 are equipped with a snap-fit ​​component 900. The crossbeam 200 is snap-fitted to the snap-fit ​​component 900 through the splicing joint 700. The wire harness assembly 600 includes a hollow wire clamping plate 601, a secondary clamping plate 602, a partition plate 603, and a threaded rod 604. The hollow wire clamping plate 601 is fixedly installed on the back of the crossbeam 200. The secondary clamping plate 602 is slidably connected to the crossbeam 200 on one side of the hollow wire clamping plate 601. The threaded rod 604 is installed through the hollow wire clamping plate 601 and the secondary clamping plate 602. The threaded rod 604 is threadedly connected to the secondary clamping plate 602. Several partition plates 603 are slidably connected to the inner side of the secondary clamping plate 602. The snap-fit ​​assembly 900 includes a snap-fit ​​connector 901. The bottom of the mounting port 505 is elastically fitted with a snap-fit ​​connector 901 that extends into the splicing cavity 504. The snap-fit ​​connector 901 is snap-fitted and assembled with the splicing connector 700.

[0015] In the above scheme: Core framework and splicing mechanism: Crossbeam 100 and crossbeam 200 are the main load-bearing members of the support. Splicing joint 2800 and splicing cavity 201 are respectively provided at both ends. Connector 500 and connector 400 are joint components used to connect and fix the crossbeams. Snap-fit ​​fixing: The snap-fit ​​component 900 is the core of the splicing function. When the splicing connector 2 800 is inserted into the splicing cavity 1 201 or the splicing cavity 504 of the connector 500, it will press down on the snap-fit ​​connector 901 and make it retract. When the locking port 701 on the splicing connector is aligned with the snap-fit ​​connector, the snap-fit ​​connector will spring up under the action of the spring to achieve quick locking. When disassembling, simply pull down the pull plate 902 connected to all snap-fit ​​connectors to release all locking at the same time and achieve quick separation. Flexible wiring: The cable bundle assembly 600 is fixed to the back of the crossbeam. By rotating the threaded rod 604, the gap between the sub-clamp plate 602 and the hollow cable clamp plate 601 can be adjusted to accommodate cable bundles of different thicknesses. The partition plate 603 can slide and be fixed on the sub-clamp plate, thereby dividing the large space into multiple independent cable trays, realizing the classification, isolation and fixation of cables, and avoiding cross-tangling.

[0016] In this embodiment, a mating interface 506 is provided on the outer side of the connector 500, and an extended telescopic square rod 501 is installed inside the mating interface 506. A guide port 503 is provided on the front side of the connector 500, and a fastening knob 502 that passes through the guide port 503 is threadedly installed on the telescopic square rod 501.

[0017] The telescopic square rod 501 can be pulled out or pushed in from the interface 506 of the connector 500, so that the spacing between the two parallel crossbeams can be flexibly adjusted according to the internal space of the metering box or the installation requirements. Reliable fixing: After adjusting to the appropriate width, tighten the fixing knob 502. Its end will press firmly against the telescopic square rod through the guide port 503, using strong friction to firmly fix it, ensuring that the bracket structure remains stable after installation.

[0018] In this embodiment, the snap-fit ​​assembly 900 further includes a pull plate 902, a spring 904, and a guide rod 905. The bottom of the snap-fit ​​connector 901 is fixedly connected to a guide rod 905 extending out of the mounting opening 505, and a spring 904 is fitted on the guide rod 905 inside the mounting opening 505. The bottom end of the guide rod 905 is fixedly mounted with the pull plate 902, and friction textures 903 are provided on both sides of the pull plate 902.

[0019] Linked unlocking and reset: The guide rod 905 ensures that the snap-fit ​​connector 901 can only move vertically to prevent it from tilting and getting stuck. The spring 904 provides the elastic force for the snap-fit ​​connector to automatically reset and lock. The pull plate 902 connects the guide rods of multiple independent snap-fit ​​connectors together to achieve one-handed operation and synchronous unlocking. The friction texture 903 on both sides of the pull plate increases the friction between your fingers and the pull plate, making it easy to pull down and disassemble even in confined spaces or while wearing gloves.

[0020] In this embodiment, the bottom of each splice 700 is provided with three sets of locking ports 701, and the locking ports 701 are mated and cooperated with the snap-fit ​​connector 901.

[0021] The three sets of locking ports 701 at the bottom of the splice correspond one-to-one with the multiple locking ports 901 at the end of the connector or crossbeam. This multi-point locking mechanism ensures that the splice will not shake or rotate around the axis after being locked, making the connection very stable and reliable, and effectively able to withstand the weight of the cable and external disturbances.

[0022] In this embodiment, a mounting base 300 is fixedly installed on the outer end of the telescopic square rod 501, and a mounting foot 301 for installation is fixedly installed on the mounting base 300.

[0023] Mounting base 300 is fixed to the inner wall of the power metering box by mounting feet 301, providing a foundation and anchor point for the entire bracket system; this allows the bracket to be pre-assembled as a complete unit and then installed into the box as a whole, or the mounting base can be fixed in the box first and then spliced ​​later, making the installation strategy flexible.

[0024] In this embodiment, the wire harness assembly 600 further includes a second fastening knob 605 and a guide block 606. A second guide opening 607 is provided on the sub-clamp plate 602, and a plurality of guide blocks 606 are slidably installed in the second guide opening 607. A partition plate 603 is installed on one side of the guide block 606, and a second fastening knob 605 that is threadedly connected to the guide block 606 is assembled on one side of the sub-clamp plate 602.

[0025] The spacing between the cable trays is flexible and adjustable: the partition plate 603 is installed in the guide port 607 through the guide block 606 and can slide along it. The operator can freely adjust the width of each cable tray according to the diameter and quantity of the cable. After adjustment, tighten the fastening knob 605 to fix the guide block and partition plate in the current position, so as to realize customized layout management for cables of different specifications.

[0026] Working principle and usage process of this utility model: When using it, the personnel should first install and fix the mounting base 300 in order to first install and fix the connector 500. The crossbeam 200 is spliced ​​together with the connector 500 via the side splice 700; During splicing, the splicing joint 700 is pushed into the splicing cavity 504, which compresses the locking joint 901. The locking joint 901 then elastically descends, ensuring that the splicing joint 700 can pass over the locking joint 901 and smoothly snap into the splicing cavity 504. At that time, the locking port 701 and the locking joint 901 are smoothly engaged and connected, completing the splicing operation between the crossbeam 200 and the connector 500. After splicing, if there is a deviation in length, the operator can first loosen the fastening knob 502 on the connector 500 to cause the telescopic square rod 501 to extend and retract within the interface 506 to meet the splicing length requirements after adjustment. After adjustment, the fastening knob 502 can be tightened, and the friction between the guide port 503 and the connector 500 is used to fix the telescopic state. When laying conductors, personnel can first rotate the threaded rod 604 according to the actual size of the conductors to adjust the distance between the hollow clamping plate 601 and the auxiliary clamping plate 602, ensuring smooth conductor traction and allowing the partition plate 603 to detach from the hollow clamping plate 601. Then, personnel loosen the guide opening 607 on the guide block 606, simultaneously loosening the partition plate 603. This allows the partition plate 603 to slide and adjust its position within the guide opening 607 via the guide block 606, thereby adjusting the conductor spacing. After adjustment, the tightening knob 605 can be rotated again to tighten the conductors. When disassembly is required, the operator can pinch the pull plate 902 with their fingers and use the friction between the fingers and the friction texture 903 to pull the pull plate 902 down. At that time, the pull plate 902 can pull down the snap-fit ​​connector 901 through the guide rod 905, causing the snap-fit ​​connector 901 to release the positioning of the splicing connector 700.

[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
