Description

Technical Field

[0001] This utility model relates to the field of distribution box manufacturing technology, and in particular to an internal wiring layout structure for an explosion-proof distribution box. Background Technology

[0002] In the industrial production sector, explosion-proof distribution boxes, as key electrical control equipment, are widely used in hazardous environments such as petroleum, chemical, and coal mines where flammable and explosive gases or dust exist. The number of integrated electrical components inside explosion-proof distribution boxes is increasing, and the wiring connections are becoming more complex. Traditional explosion-proof distribution box internal wiring layouts have the following problems: The lack of effective zone isolation in the circuits, with high-voltage and low-voltage lines, as well as power and control lines intertwined, easily generates electromagnetic interference, affecting the normal operating accuracy of the equipment. The internal space is underutilized, and the power lines are intertwined with the low-voltage lines. The messy wiring makes it difficult to quickly identify and troubleshoot faulty lines during later maintenance, which prolongs the downtime for repairs. Therefore, a wiring layout structure for an explosion-proof distribution box is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where the lack of effective partitioning and isolation of circuits leads to the intertwining of high-voltage and low-voltage circuits, and to propose a circuit layout structure for the internal wiring of an explosion-proof distribution box.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An internal wiring layout structure for an explosion-proof distribution box includes a wire trough, a partition, and a cover plate; The bottom of the cable tray is fixed to the distribution box with bolts, and multiple support blocks are provided on both sides of the bottom. The top of the support blocks is provided with a step. The partition is supported on the step, and its bottom has multiple circular holes I. The bottom of the groove has multiple columns corresponding to the circular holes I. Bolts pass through the circular holes I and are threaded to the columns.

[0005] In one possible design, multiple upright plates are provided on both sides of the cable tray, and limit blocks are provided on the top of each upright plate.

[0006] In one possible design, the top of the upright plates on both sides of the cable tray is provided with a groove, and the bottom of the cover plate is provided with a guide rail that slides with the groove. The cover plate is detachably connected to the top of the cable tray.

[0007] In one possible design, the limiting block is a raised structure, and its height is lower than that of the upright plate.

[0008] In one possible design, the surface of the partition has multiple square holes.

[0009] In one possible design, the cable trays, partitions, and covers are made of ABS.

[0010] In one possible design, the bottom of the trough has multiple circular holes II.

[0011] In this application: The cable tray serves as the basic carrier for cable layout. It has a round hole II at the bottom and is fixed to the distribution box with bolts to provide stable support for the overall structure. The support blocks on both sides of the bottom have steps on top to provide load-bearing capacity for the partition. The columns at the bottom of the cable tray correspond to the round holes I at the bottom of the partition. Bolts pass through the round holes I and are threaded to the columns to firmly fix the partition and prevent it from shifting during equipment operation or maintenance. The partition divides the wiring into upper and lower layers. The high-voltage wiring is placed below the partition, and the low-voltage wiring is placed above the partition. Multiple square holes on the surface of the partition are used for internal air circulation. The vertical plates on both sides of the cable tray are evenly spaced, and the gaps between the vertical plates are used for the entry and exit of the cable tray. Together with the limiting block at the top, they can limit the cable passing through the cable tray, prevent the cable from slipping out of the cable tray, and further regulate the cable route. The cover plate is detachably connected by sliding engagement with the grooves on the top of the upright plates on both sides of the cable tray via the bottom guide rail.

[0012] Beneficial effects: In this utility model, the internal wiring layout structure of the explosion-proof distribution box uses components such as partitions, support blocks, steps, and columns in combination. The support blocks on both sides of the bottom are provided with steps on the top to provide load-bearing capacity for the partitions. The partitions divide the wiring into upper and lower layers, which can separate different types of wiring such as high-voltage and low-voltage, power and control wiring, effectively reducing electromagnetic interference and ensuring the accuracy of equipment operation. In addition, the wiring layout is more standardized after separation, which facilitates the troubleshooting of wiring faults. In this utility model, the internal wiring arrangement structure of the explosion-proof distribution box uses components such as guide rails, grooves, cover plates, and wire troughs in combination. The guide rails and the grooves on the top of the upright plates on both sides of the wire trough slide together to achieve a detachable connection. This connection method not only facilitates the quick disassembly and assembly of the cover plate and the installation and maintenance of the wiring, but also prevents the leakage of sparks and arcs generated by the internal wiring, playing a key role in explosion-proof protection. In this invention, the isolation effect of the partition allows for the separate arrangement of different types of lines, such as high-voltage and low-voltage lines, and power and control lines, resulting in a more standardized line arrangement, effectively reducing electromagnetic interference and ensuring the operational accuracy of the equipment.
