Description

Technical Field

[0001] This application relates to the technical field of meter box cable fixing, and in particular to a meter box circuit cable fixing structure. Background Technology

[0002] In the fields of industrial electrical equipment and control cabinets, the enclosure structure is an important component for protecting internal components and ensuring stable equipment operation. However, traditional electrical equipment enclosures have many inconveniences in actual use, especially in the installation of cables and the removal and installation of cover plates.

[0003] Traditional enclosures typically feature closed or semi-closed fixed structures. When external electrical components require cable routing, the lack of dedicated cable channels forces cables to pass through the enclosure's edges or narrow openings. This not only leads to messy, tangled cables, affecting the cleanliness and safety of the equipment's interior, but also risks malfunctions due to cable compression and abrasion. Furthermore, while some enclosures may have cable routing openings, their fixed positions and non-adjustable dimensions make them unsuitable for accommodating different cable specifications and quantities, resulting in poor flexibility.

[0004] In the connection design between the cover plate and the frame, traditional structures mostly use bolt fastening or a single clip. If bolt fastening is used, tools are required for each disassembly and assembly of the cover plate, making the operation cumbersome and time-consuming, especially during equipment maintenance or repair, significantly reducing work efficiency. If a single clip connection is used, although the disassembly and assembly speed is improved, the fixed position of the clip makes it difficult to adapt to subtle structural changes in the frame due to cable installation, etc., easily leading to unstable connections, affecting the enclosure's sealing and protective performance, allowing dust, moisture, and other impurities to enter the enclosure and damage internal components. Therefore, to solve the above problems, this application provides a circuit cable fixing structure for a meter box. Utility Model Content

[0005] To address the aforementioned issues, this application provides a circuit cable fixing structure for a meter box.

[0006] This application provides a circuit cable fixing structure for a meter box, including a box body;

[0007] The frame is installed on the enclosure and has a U-shaped notch. A detachable piece is connected to the U-shaped notch through a connecting section. After the detachable piece is removed, the cables of external electrical components can be routed through the U-shaped notch inside the frame.

[0008] The cover plate is used to enclose the frame. Its bottom end is connected to the frame by a lower latch, and its top end is engaged by a set of phases in the control structure and connecting section.

[0009] The enclosure is secured to the frame with bolts. At the U-shaped notch on the frame, a detachable section is connected via a connecting segment. After removing the detachable section, external electrical components can have their cables routed inside the frame. The bottom of the cover plate is directly snapped to the frame via a lower locking rod, while the upper locking rod at the top is adjusted to the position of the detachable section connection segment without removal by using the displacement of a slider in the adjustment groove.

[0010] Preferably, the housing is provided with threaded holes and is fixedly connected to the frame by bolts.

[0011] Preferably, the control structure includes an upper locking rod and a pressing section. Controlling the pressing section to move downwards allows the lower locking rod to detach from the connecting section, enabling convenient assembly and disassembly of the cover plate and the frame.

[0012] Preferably, the upper locking lever is linked to the pressing section, and the control structure is also equipped with a spring for resetting after the lower locking lever is disengaged.

[0013] Preferably, the top end is provided with an adjustment groove, and a slider is provided inside the adjustment groove. The slider is elastically connected to the upper locking rod by a spring.

[0014] Preferably, the upper locking rod is moved within the adjustment groove by a slider to be adjusted to correspond to the position of the connecting section of the detachable piece that has not been removed, thereby achieving locking with the frame.

[0015] Preferably, the spring provides a reset force to the lower latch, so that the lower latch returns to its initial latching state after the pressing force disappears.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] The enclosure is secured to the frame with bolts. At the U-shaped notch on the frame, a detachable section is connected via a connecting segment. After removing the detachable section, external electrical components can have their cables routed inside the frame. The bottom of the cover plate is directly latched to the frame via a lower locking rod, while the top locking rod is adjusted to the position of the detachable section connection segment by the displacement of a slider in the adjustment slot. By pressing down on the lower section, the lower locking rod can be disengaged from the connecting segment, thus facilitating the assembly and disassembly of the cover plate and the frame.

[0024] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0025] Example 1:

[0026] A circuit cable fixing structure for a meter box, as shown in the reference. Figure 1 - Figure 5 The housing 1 has a threaded hole 11, which is fixedly connected to the frame 2 by bolts 12. The frame 2 is installed on the housing 1 and has a U-shaped notch. The U-shaped notch is connected to a detachable piece 21 by a connecting section 211. After the detachable piece 21 is removed, the cables of external electrical components can be routed through the U-shaped notch inside the frame 2.

[0027] The cover plate 3 is used to close the frame 2. Its bottom end is connected to the frame 2 by a lower locking rod 4, and its top end is connected to a set of phases in the connecting section by a control structure 5.

[0028] The control structure 5 includes an upper locking rod 51 and a pressing section 52. Controlling the pressing section 52 downwards allows the lower locking rod 4 to disengage from the connecting section 211, facilitating easy assembly and disassembly of the cover plate 3 and the frame 2. The upper locking rod 51 and the pressing section 52 are linked, and the control structure 5 also includes a spring 54 for resetting the lower locking rod 4 after disengagement. An adjustment groove 31 is located at the top, inside which a slider 53 is installed. The slider 53 is elastically connected to the upper locking rod 51 via the spring 54. The upper locking rod 51 moves within the adjustment groove 31 via the slider 53, adjusting to correspond to the position of the connecting section 211 of the detachable piece 21 that has not been removed, thus engaging with the frame 2. The spring 54 provides a reset force for the lower locking rod 4, allowing it to return to its initial latched state after the pressing section 52's control force disappears.

[0029] The specific implementation process is as follows:

[0030] I. Component Assembly

[0031] Frame and box fixed

[0032] By using bolt 12 to fit the threaded hole 11 on the housing 1, the frame 2 is aligned with the installation position of the housing 1, and the bolt 12 is screwed into the threaded hole 11 to complete the detachable fixation of the frame 2 and the housing 1, so that the two form a stable installation foundation.

[0033] Detachable panels and frame adapter

[0034] At the U-shaped notch of frame 2, the detachable piece 21 is connected by connecting section 211. The detachable piece and connecting section can be integrated or pre-assembled by snap-fit / screw connection to form a complete closed / semi-closed structure of the frame. The detachable piece can be removed as needed for cable routing.

[0035] Cover plate and frame pre-assembled

[0036] Initial connection of the lower locking rod: Align the lower locking rod 4 at the bottom of the cover plate 3 with the corresponding buckle position of the frame 2, and gently push the cover plate to make the lower locking rod 4 snap into the frame, thus achieving initial positioning of the bottom of the cover plate.

[0037] Upper lever position adjustment: The slider 53 slides within the adjustment groove 31 at the top of the cover plate, causing the upper lever 51 to move. During the sliding process, the slider 53 moves stably along the adjustment groove 31, precisely adjusting the upper lever 51 to the position corresponding to the connecting section 211 of the detachable piece 21 that has not been removed. Then, the upper lever 51 is gently pushed to engage with the connecting section 211, completing the initial assembly of the cover plate 3 and the frame 2. At this time, the spring 54 of the control structure 5 is in its natural state, reserving restoring force for subsequent disassembly operations.

[0038] II. Cable installation and cover plate removal / removal operations

[0039] Cable installation and removal detachable plate

[0040] When external electrical components require cable access to the equipment, remove the detachable piece 21 as needed: if the detachable piece and the connecting section 211 are snap-fitted, pull the detachable piece outwards directly; if they are screw-fitted, unscrew the corresponding screws to remove it. After removal, the cable passes through the U-shaped notch into the inside of the frame 2 and is arranged along the pre-set wiring space within the frame, such as the interlayer gaps. After completion, reinstall the detachable piece 21 back into the connecting section 211 to restore the frame's sealing.

[0041] Cover plate disassembly, maintenance / repair scenarios

[0042] If maintenance or repair is required on the internal frame or the inside of the housing, operate the pressing section 52 of the control structure 5: press the pressing section 52 downwards, the pressing section will move the upper locking rod 51 and the lower locking rod 4 downwards in sync, the lower locking rod 4 will compress the spring 54 and disengage from the connecting section 211 of the frame; at this time, the upper locking rod 51 will also be released from the connecting section 211, and the cover plate 3 will be pulled outwards, so that the cover plate can be removed from the frame 2 as a whole, exposing the internal space of the equipment for easy maintenance.

[0043] Cover plate reinstalled

[0044] After the maintenance is completed, reinstall the cover plate 3: First, align the lower locking rod 4 at the bottom of the cover plate with the frame buckle position, and gently push it to lock the lower locking rod in; then slide the slider 53 to adjust the position of the upper locking rod 51, align it with the connecting section 211 and lock it in, the spring 54 returns to its natural state, the upper locking rod 51 and the lower locking rod 4 are locked with the frame again, the cover plate 3 and the frame 2 are re-securely assembled, and the equipment returns to normal use.

[0045] III. Key Component Collaboration Principle

[0046] Frame and housing: The mechanical connection through bolts 12 and threaded holes 11 ensures installation stability and supports the disassembly and replacement of the frame in the future, adapting to equipment upgrade or maintenance needs.

[0047] Detachable sections and connecting segments: The flexible detachable design provides a "temporary channel" for cable insertion, solving the problem of difficult cable arrangement in traditional enclosed frames. At the same time, the detachable sections can be reinstalled to restore the integrity of the frame without affecting the equipment's protective performance.

[0048] Cover plate and control structure: The lower locking rod 4 and the upper locking rod 51 work together with the connecting section 211 of the frame to achieve "dual-point" locking and fixing of the cover plate to ensure sealing; the linkage between the pressing section 52 and the spring 54 makes the disassembly and assembly operation simple and efficient by pressing-releasing-resetting, reducing the difficulty of operation for maintenance personnel and improving the convenience of use throughout the entire life cycle of the equipment.
