[0001] This utility model relates to the field of internal cable tray technology for distribution boxes, specifically to an internal cable tray structure for distribution boxes that facilitates wiring. Background Technology

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits.

[0003] Traditional wiring methods for distribution boxes have the following problems:

[0004] 1. The wires are laid directly inside the box, resulting in a messy interior that not only affects the aesthetics but also poses a safety hazard.

[0005] 2. Protective covers and cable trays are mostly connected by plugging, which is inconvenient to install when the space inside the distribution box is small.

[0006] 3. The wires are prone to tangling in the wire groove, and the poor design of the wire outlet can easily lead to wire wear.

[0007] Therefore, a cable tray structure for the internal wiring of the distribution box is proposed to facilitate wiring. Utility Model Content

[0008] The present invention aims to solve the problems mentioned in the background art by providing an internal cable tray structure for a power distribution box that facilitates wiring.

[0009] The specific technical solution is as follows:

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0034] The wiring duct structure inside the distribution box provided in this embodiment facilitates wiring, such as... Figures 1-6 As shown, the device includes a cable tray 1 installed inside a distribution box. A protective cover 2 is provided on the top of the cable tray 1. Clamping mechanisms 3 are provided on the top of the cable tray 1 and on both sides of the protective cover 2. The cable tray 1 is designed to accommodate the wires, preventing them from being directly arranged inside the distribution box and causing it to become messy. The protective cover 2 is designed to seal the top of the cable tray 1, thus preventing the wires from being exposed during actual use, which would affect aesthetics and safety. The clamping mechanisms 3 are designed to snap the protective cover 2 onto the top of the cable tray 1, preventing the wires inside from being exposed. At the same time, it avoids the problem of the traditional protective cover 2 being plugged into the cable tray 1, which would affect the installation of the protective cover 2 relative to the cable tray 1 in the small space inside the distribution box.

[0035] The clamping mechanism 3 includes clamping rods 301 disposed on the front and rear sides of the protective cover 2. A slot 302 is provided on the top of the wire trough 1. The clamping rods 301 are snapped into the inside of the slot 302. The slot 302 is used to accommodate the clamping rods 301, thereby snapping the clamping rods 301 onto the outside of the wire trough 1 to achieve the connection between the protective cover 2 and the wire trough 1. This avoids the problem that traditional plug-in connections cannot be installed when the internal space of the distribution box is small.

[0036] The protective cover 2 has evenly distributed receiving cavities 307 on its front and rear sides. A limiting rod 303 is inserted inside the receiving cavity 307. One side of the limiting rod 303 is fixedly connected to the clamping rod 301. The receiving cavity 307 is used to store the limiting rod 303 and connect the clamping rod 301 to the protective cover 2.

[0037] The inside of the groove 1 and at the top and bottom of the receiving cavity 307 are provided with sliding grooves 304. A slider 306 is slidably connected inside the sliding groove 304. One side of the slider 306 is fixedly connected to the limiting rod 303. The sliding groove 304 and the slider 306 are used to limit the position between the limiting rod 303 and the slot 302, thereby realizing the connection between the clamping rod 301 and the protective cover 2 and preventing the clamping rod 301 from detaching from the protective cover 2.

[0038] A spring 305 is fixedly installed on one side of the slider 306. One side of the spring 305 contacts the inner cavity of the slide groove 304. The spring 305 is used to drive the slider 306 to move the limiting rod 303 into the receiving cavity 307. At the same time, it pulls the clamping rod 301 closer to the side of the protective cover 2, so that the clamping rod 301 is engaged with the inside of the slot 302, and the protective cover 2 is engaged with the top of the wire groove 1.

[0039] The front and rear sides of the wire trough 1 are provided with evenly distributed through grooves 5. The top of the through groove 5 is smaller than the bottom. The through groove 5 is used to lead out the wires stored inside the wire trough 1 and connect them to electrical components. By setting the through groove 5 to be smaller at the top and larger at the bottom, the wires are located inside the larger part of the through groove 5 when they extend through the through groove 5, which avoids the wires from rubbing against the inner wall of the through groove 5. The top of the through groove 5 is set to be smaller so that the wires are not allowed to extend out of the inside of the through groove 5 when the protective cover 2 is opened.

[0040] Multiple sets of evenly distributed limiting plates 4 are fixedly installed on the inner side of the wire trough 1. The openings between the limiting plates 4 correspond to the through groove 5. The limiting plates 4 are used to divide the wires stored inside the wire trough 1 to prevent the wires from getting tangled inside the wire trough 1 and affecting subsequent wiring.

[0041] Two connecting blocks 7 are fixedly installed on the front and rear sides of the cable tray 1. Bolts 6 are inserted inside the connecting blocks 7. The bolts 6 and the connecting blocks 7 are used to install the whole into the inside of the distribution box to realize the storage and fixation of the wires.

[0042] Working principle:

[0043] 1. Cable tray installation and wire arrangement

[0044] The wire trough 1 is fixed inside the distribution box by bolts 6 and connecting blocks 7. The wires are placed into the wire trough 1, and the limiting plate 4 is used to separate different wires to avoid tangling.

[0045] 2. Wire lead-out and connection

[0046] The wires extend through the gap of the limiting plate 4 to the through groove 5. The large bottom design of the through groove 5 reduces friction and allows them to be led out in an orderly manner to connect with electrical components.

[0047] 3. Protective cover closing process

[0048] Pull the clamping rod 301 away from the protective cover 2, compress the spring 305, and place the protective cover 2 on top of the wire groove 1; release the clamping rod 301, the spring 305 rebounds and pushes the slider 306 to slide along the slide groove 304, causing the limit rod 303 to retract; the clamping rod 301 is inserted into the slot 302, realizing a stable connection between the protective cover 2 and the wire groove 1.

[0049] 4. Maintenance and Activation

[0050] When maintenance is required, pull the clamping rod 301 to disengage it from the slot 302, and the protective cover 2 can be opened. At this time, the top of the through slot 5 is designed to prevent the wire from accidentally coming out.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
