A cross-connection board and its three-phase power metering box

Abstract

This invention relates to the field of electrical equipment cable management, specifically disclosing a non-crossing wiring board and its three-phase power metering box. The non-crossing wiring board includes a plate-shaped body with several through holes. Its surface has multiple wiring grooves communicating with the through holes and bending grooves for changing the direction of the wires. The connections between each groove are smooth transitions, forming preset independent guide paths. By threading cables through different through holes and laying them along corresponding grooves, multiple cables can be arranged in an orderly manner without crossing or overlapping on the same plane. Through a structured design of physical isolation and preset paths, this invention fundamentally solves the industry problems of prominent safety hazards, poor heat dissipation, unclear labeling, and extremely inconvenient maintenance caused by haphazardly bundled and overlapping cables in traditional cabinets, significantly improving the wiring standardization, operational reliability, and maintenance efficiency of electrical equipment.

Description

Technical Field

[0001] This invention belongs to the field of electrical equipment cable management, specifically a cross-connection wiring board and its three-phase power metering box. Background Technology

[0002] In electrical equipment, communication cabinets, and various industrial control enclosures, cable laying and management are fundamental and crucial aspects. Cables not only carry electrical energy and signals, but their arrangement directly impacts the internal space utilization, heat dissipation, ease of maintenance, and long-term operational safety and reliability. Typically, cables are introduced through an inlet port on one side of the enclosure, connecting to internal components such as circuit breakers, electricity meters, contactors, or terminal blocks, and then exiting through their outlet ports. Ideally, cable paths should be clear, clearly labeled, and free from interference to prevent signal crosstalk, localized overheating, and facilitate troubleshooting and cable replacement.

[0003] Currently, common cable management methods rely heavily on the experience of construction workers for manual bundling or the use of simple plastic cable trays and ties for rough categorization. However, these methods have a common and prominent drawback: they struggle to completely prevent the inevitable crossing and overlapping of multiple cables within the confined three-dimensional space and densely packed components of a cable enclosure. Cable crossings not only lead to a chaotic and aesthetically unpleasing internal layout but also introduce a series of safety hazards. For example, long-term compression at crossing points can accelerate the aging or even damage of the insulation layer, increasing the risk of short circuits. During maintenance, moving one cable can easily disturb other cables, affecting system stability, and locating specific lines is time-consuming and laborious. Therefore, achieving a neat, "cross-free" cable arrangement within a limited plane or space, ensuring independent and clearly identifiable paths, has become a pressing technical problem that needs to be solved to improve the design level and engineering quality of electrical enclosure products. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a cross-free wiring board, which solves the problems of prominent safety hazards, low maintenance efficiency, and chaotic wiring caused by the disorderly laying of multiple cables in the enclosure, resulting in mutual crossing and overlapping.

[0005] A cross-connected wiring board includes a wiring board body with a plurality of through holes through the wiring board body and a wiring groove on one side of the wiring board body, wherein the through holes and the wiring groove are interconnected.

[0006] Preferably, the number of through holes is equal to the number of wiring slots, and the number is at least four.

[0007] Preferably, the wiring board body is further provided with a bending groove, which is used to change the wiring guidance of the wiring groove.

[0008] Preferably, the curved groove is connected to the wiring groove.

[0009] Preferably, the connection between the curved groove and the wiring groove is a smooth transition.

[0010] Preferably, the connection between the through hole and the wiring groove is a smooth transition.

[0011] Preferably, the through holes include a first through hole, a second through hole, a third through hole, and a fourth through hole arranged side by side in sequence;

[0012] The wiring channel includes a first wiring channel, a second wiring channel, a third wiring channel, and a fourth wiring channel;

[0013] The first wiring groove is connected to the first through hole, the second wiring groove is L-shaped and bypasses the second through hole and then connects to the third through hole, the third wiring groove is Z-shaped and bypasses the third through hole and then connects to the second through hole, and the fourth wiring groove is connected to the fourth through hole.

[0014] The cross-connecting wiring board is made of one-piece molded fire-resistant engineering plastic, which has a flame retardant rating of UL94 V-0.

[0015] A three-phase electricity metering box includes: a box body, a three-phase electricity meter installed inside the box body, and at least one circuit breaker installed inside the box body.

[0016] And as described above, a cross-connection board is installed inside the enclosure and located between the three-phase energy meter and the circuit breaker;

[0017] The input and output cables of the three-phase energy meter are guided through different through holes and wiring grooves of the non-crossing wiring board to achieve non-crossing arrangement of phase lines.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By introducing a physical isolation structure with a predetermined guiding path, the free and scattered cables are constrained into regular and independent channels, which fundamentally avoids the disorderly crossing between cables of different paths and realizes the parallel and orderly operation of multiple cables in a limited space.

[0020] Based on the smooth transition of the channel design and the flexible layout, this invention not only ensures that the cable is subjected to uniform force and is not easily worn at the turning and entry / exit points, but also adapts to a variety of application scenarios from simple power distribution to complex metering through a modular approach, realizing a systematic improvement in the safety, reliability and maintainability of the cable management system.

[0021] Ultimately, this invention transforms the core concept of "no intersection" into an intuitive and robust physical entity, turning chaotic cable layouts into clearly identifiable standardized engineering, and providing effective and universal basic support for the orderly installation, convenient operation and maintenance, and long-term safe and stable operation of electrical equipment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 3 As shown in Figure 5:

[0031] Example 1: The present invention provides a cross-connected wiring board, including a wiring board body 1, a plurality of through holes 2 are formed on the wiring board body 1, and a wiring groove 3 is formed on one side of the wiring board body 1, with the through holes 2 and the wiring groove 3 communicating with each other.

[0032] Specifically, the number of through holes 2 and wiring slots 3 is equal, and the number is at least 4.

[0033] Specifically, the wiring board body 1 is also provided with a bending groove 4, which is used to change the wiring guidance of the wiring groove 3.

[0034] Specifically, the bending groove 4 is connected to the wiring groove 3.

[0035] Specifically, the connection between the bending groove 4 and the wiring groove 3 is a smooth transition.

[0036] Specifically, the connection between the through hole 2 and the wiring groove 3 is a smooth transition.

[0037] As can be seen from the above, the cross-free wiring board provided by the present invention includes a wiring board body 1, on which a plurality of through holes 2 are provided, and a wiring groove 3 is provided on one side of the wiring board body 1. The through holes 2 and the wiring groove 3 are interconnected, and the number of the two is equal, with a minimum of 4.

[0038] In addition, a bending groove 4 is provided on the wiring board body 1. The bending groove 4 is connected to the wiring groove 3 and is used to change the wiring guidance of the wiring groove 3.

[0039] In terms of structural design, the connection between the through hole 2 and the wiring groove 3, as well as the connection between the bent wire groove 4 and the wiring groove 3, are all smooth transitions, thereby ensuring the smoothness and stability of wiring.

[0040] When using, such as Figure 6 As shown, the wiring board body 1 is fixed to the inner wall of the electrical box. After the cable passes through the through hole 2, it is guided by the wiring groove 3 and the bending groove 4, which can realize the non-crossing and orderly arrangement of multiple cables in the same plane.

[0041] The bending groove 4 changes the cable path, thereby allowing the cable leaving the wiring board body 1 to stay away from the inner wall of the electrical box.

[0042] like Figure 4 As shown:

[0043] Example 2: This example is basically the same as the previous example, except that it also includes a first through hole 21, a second through hole 22, a third through hole 23 and a fourth through hole 24 arranged side by side in sequence;

[0044] The wiring channel 3 includes a first wiring channel 31, a second wiring channel 32, a third wiring channel 33, and a fourth wiring channel 34;

[0045] The first wiring groove 31 is connected to the first through hole 21. The second wiring groove 32 is L-shaped and passes around the second through hole 22 before connecting to the third through hole 23. The third wiring groove 33 is Z-shaped and passes around the third through hole 23 before connecting to the second through hole 22. The fourth wiring groove 34 is connected to the fourth through hole 24.

[0046] Specifically, the cross-connector board is made of one-piece molded fire-resistant engineering plastic, which has a flame retardant rating of UL94 V-0.

[0047] As can be seen from the above, this embodiment further defines the specific layout of the through hole 2 and the wiring groove 3. The through hole 2 includes a first through hole 21, a second through hole 22, a third through hole 23 and a fourth through hole 24 arranged side by side in sequence. Correspondingly, the wiring groove 3 is specifically defined as a first wiring groove 31, a second wiring groove 32, a third wiring groove 33 and a fourth wiring groove 34.

[0048] Each wiring groove and through hole forms a specific connection relationship: the first wiring groove 31 and the fourth wiring groove 34 are directly connected to the first through hole 21 and the fourth through hole 24, respectively; while the second wiring groove 32 is L-shaped, bypassing the second through hole 22 and connecting to the third through hole 23, and the third wiring groove 33 is Z-shaped, bypassing the third through hole 23 and connecting to the second through hole 22, as detailed below. Figure 4 As shown;

[0049] Through the L-shaped and Z-shaped meandering design, this layout achieves cross-traffic avoidance and orderly guidance of multiple cables in a limited planar space, ensuring the independence of cable paths and the neatness of wiring, and effectively improving the space utilization and organization of the wiring board.

[0050] L-shaped and Z-shaped paths are merely preferred embodiments; any channel design that can achieve non-intersecting guidance falls within the scope of this invention.

[0051] Example 3: This example provides a three-phase energy metering box, including a box body, a three-phase energy meter installed inside the box body, at least one circuit breaker installed inside the box body, and a cross-connection wiring board as described in Example 1 or Example 2 above. The cross-connection wiring board is installed inside the box body and located between the three-phase energy meter and the circuit breaker. The input and output cables of the three-phase energy meter are guided through different through holes and wiring grooves of the cross-connection wiring board to achieve cross-connection of the phase lines.

[0052] Furthermore, the edges of the non-crossing wiring board are equipped with clips that can slide and snap into pre-set slots on the electrical box for fixation.

[0053] As can be seen from the above, the three-phase power metering box in this embodiment, by integrating a cross-connection-free wiring board, transforms the traditional free and messy cable laying method inside the box into a neat arrangement along a preset physical path. This wiring board is located between the power meter and the circuit breaker, and utilizes its through holes and wiring channels to guide and isolate the three-phase incoming and outgoing lines in the area where multiple cables converge, achieving complete physical separation and eliminating cable crossings, overlaps, and tangles. This structured wiring method not only fundamentally eliminates the risks of insulation wear, localized overheating, and short circuits caused by cable crossings, significantly improving electrical safety and operational reliability, but also makes the internal layout of the box extremely clear and orderly, greatly facilitating construction and installation, line identification, and subsequent maintenance, repair, and expansion operations, demonstrating the outstanding value of this invention in practical engineering applications.
