Description

Technical Field

[0001] This invention relates to the field of metering equipment, and in particular to metering boxes with built-in cable management structures. Background Technology

[0002] Electricity metering boxes are used to centrally install electricity meters and related electrical components. Their internal wiring is numerous and of various specifications, and the rationality of the wiring structure directly affects line safety and installation and maintenance efficiency. Existing technologies, such as the Chinese utility model patent with publication number CN221428352U, disclose a non-metallic electricity metering box, relating to the technical field of electricity metering boxes. It includes a box body divided into a control area and an installation area. The control area is used for centralized placement of wires and switch installation, while the installation area is used for meter installation. A wiring hole for power supply lines is provided between the control area and the installation area. A support plate is rotatably connected to the back of a bracket, and a fixing groove is provided on the inner wall of the installation area for the support plate to abut against after rotation.

[0003] However, the aforementioned existing technologies still have certain shortcomings: they mainly achieve cable storage through the cable take-up shell in the control area, but this storage method can only achieve centralized placement of the cables and cannot effectively limit the cables, resulting in the internal cables being prone to loosening and tangling; at the same time, although some existing solutions use cable ties to bundle the cables to improve neatness, especially at the right angles of the cable take-up shell, multiple cable ties are needed to bundle and tighten them to ensure neatness. If a single cable has a problem and needs to be repaired, since the cable ties are a one-time fixing structure, the cable ties must be cut before the cable can be separated, which is cumbersome and reduces maintenance efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a metering box with a built-in cable management structure. This invention achieves independent control of the tension of multiple cables through a combination of a fine-tuning body and guide posts, resulting in neat and orderly wiring within the box and facilitating subsequent maintenance operations.

[0006] In the aforementioned metering box with a built-in cable management structure, the guide post includes a shaft passing through a guide groove. The end of the shaft is provided with a nut and a guide wheel. The guide wheel is used to limit and guide the cable. The upper surface of the nut contacts the lower surface of the guide plate, and the upper end of the shaft has a rotatable locking button.

[0007] In the aforementioned metering box with a built-in cable management structure, the fine-tuning body includes a fine-tuning block disposed on a transverse optical rod and a transverse screw. A guide block is provided at the lower part of the fine-tuning block, and an optical axis passing through the fine-tuning block and an adjusting rod threadedly connected to the fine-tuning block are provided at the upper end of the guide block. The guide block is used to realize the tightness adjustment of the bidirectional displacement of the line.

[0008] The cable holder includes a main body, the first semi-circular groove is disposed on the upper surface of the main body, and the two ends of the main body have fixing holes, and screws for connecting to the cable tray are disposed in the fixing holes.

[0009] In the aforementioned metering box with a built-in cable management structure, the cable routing board is provided with a positioning block, the lower surface of the main body end has a positioning groove that fits with the positioning block, and the screw is connected to the positioning block.

[0010] In the aforementioned metering box with a built-in cable management structure, the upright has a sliding groove, and one end of the elastic cable clamp is embedded in the sliding groove.

[0011] In the aforementioned metering box with a built-in cable management structure, the elastic cable clamping body includes a cable clamping main block. The upper end of the cable clamping main block has a T-shaped part that fits into the slide groove. One side of the cable clamping main block has a flat part that passes through the slide groove. A spring is provided on the flat part, and one end of the spring is connected to the upright frame. The other side of the cable clamping main block has a pressure block, and the second semi-circular groove is provided on the lower surface of the pressure block.

[0012] In the aforementioned metering box with a built-in cable management structure, the upper end of the stand has a positioning pin, the flat part has a positioning protrusion, and the end of the spring is respectively sleeved on the positioning pin and the positioning protrusion.

[0013] In the aforementioned metering box with a built-in cable management structure, one side of the main cable clamp has a pair of symmetrically arranged ribs.

[0014] In the aforementioned metering box with a built-in cable management structure, the bottom of the rib plate has a dovetail groove, and the upper end of the pressure block has a dovetail strip that matches the dovetail groove.

[0015] Compared with the prior art, the present invention has the following advantages: 1. In this invention, the cable is bent at the right angle of the cable management frame, and the cable is wound around the guide post at the end of the right angle frame. Each cable corresponds to one guide post, which realizes the regular wiring of the cable, avoids the cable from being loose or crossing, and achieves the initial cable limit. In addition, each cable corresponds to a fine-tuning body, which can independently adjust the tightness of a single cable. After each cable is completed, there may be looseness. By adjusting the tension of the cable in different directions through the fine-tuning body, the tightness of the cable is kept at a suitable level, which improves the flexibility of adjustment. During subsequent cable maintenance, the position of the fine-tuning body of the corresponding cable is adjusted to loosen the corresponding cable, which is convenient for maintenance personnel to perform maintenance.

[0016] 2. When wiring inside the enclosure, the wires will be arranged along the cable tray. Pulling up the elastic cable clamp separates the first and second semicircular grooves, securing the wires in the first semicircular groove of the cable clamp. Releasing the elastic cable clamp causes the first and second semicircular grooves to align, thus positioning the wires and improving the neatness of multiple wires. The elastic cable clamp provides elastic clamping force through elastic components, eliminating the need for disposable fasteners such as cable ties. During installation, the elastic cable clamp can be directly pried open and inserted into the clamping groove without cutting any parts. The operation is simple and quick, greatly improving the efficiency of installation, debugging, and subsequent maintenance.

[0017] 3. The elastic clamping body, through the T-shaped part and the slot of the upright frame, combined with the elastic reset function of the spring, ensures stable and long-lasting clamping force and avoids loosening after long-term use. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example: A metering box with a built-in cable management structure, including box body 1, as shown in the attached figure. Figure 1 As shown, a cable management frame 3, consisting of multiple cable trays 2, is installed on the inner wall of the housing 1, as shown in the attached diagram. Figure 2 As shown, the assembled cable management frame will form multiple mounting chambers, in which multiple electronic components will be installed. Control components, such as disconnect switches, relays, or terminal blocks, will be installed within the mounting chambers. An electricity meter or multi-functional power meter will be installed on the cabinet door. A right-angle bracket 30 is installed at the right-angle end of the cable management frame 3, as shown in the attached diagram. Figure 6 As shown, the right-angle bracket is welded to the cable tray. A guide plate 31 is installed at the end of the right-angle bracket 30. Both ends of the guide plate are connected to the right-angle bracket by screws. The guide plate 31 has a guide groove 32, and multiple guide posts 33 for cable positioning are installed within the guide groove 32. Each guide post 33 includes a shaft 331 that passes through the guide groove 32, as shown in the attached diagram. Figure 7As shown, the end of the shaft 331 is equipped with a positioning nut 332 and a guide wheel 333. The guide wheel 333 is used to limit and guide the wiring. The upper surface of the positioning nut 332 contacts the lower surface of the guide plate 31, and the upper end of the shaft 331 has a rotatable locking button 334. Each wiring corresponds to a guide post. Each wiring is aligned, and the wiring wraps around the guide wheel. By unscrewing the locking button, the shaft can move within the guide groove. Since this is a turning point for the wiring, the length and direction of each wiring will affect the arrangement of the wiring at the corner. Therefore, setting the guide post as a movable structure can improve the convenience of wiring. At the same time, the two ends of the wiring turning are supported by the wheel structure, which can ensure the stability of the wiring turning. After determining the position of the guide wheel, tighten the locking button to fix the entire guide post in a certain position in the guide groove. The right-angle bracket 30 is equipped with parallel transverse guide rods 34 and transverse screws 35. Movable fine-tuning bodies 36 are mounted on the transverse guide rods 34 and 35, allowing for bidirectional adjustment of the line's tension. Multiple adjusting nuts 37 for positioning the fine-tuning bodies are mounted on the transverse screws 35. Each fine-tuning body 36 includes fine-tuning blocks 361 mounted on the transverse guide rods 34 and 35, as shown in the attached figure. Figure 8 As shown, a guide block 362 is installed at the lower part of the fine-tuning block 361. The upper end of the guide block 362 is provided with an optical shaft 363 passing through the fine-tuning block 361 and an adjusting rod 364 threadedly connected to the fine-tuning block 361. The end of the adjusting rod 364 is movably connected to the guide block 362. The upper end of the guide block has an inner groove. The end of the adjusting rod is a stepped shaft structure. The stepped shaft structure is set in the inner groove so that the adjusting rod will not drive the guide block to rotate when it rotates. The guide block 362 is used to realize the tightness adjustment of the bidirectional displacement of the line. The wiring is secured within the groove of the guide block. The fine-tuning block can move axially along the transverse guide rod to adjust the tightness of the wiring in that direction. An adjusting nut is located on each side of the fine-tuning block, providing bidirectional clamping and positioning. After determining the position of the fine-tuning block, tighten the adjusting nuts on both sides. Rotating the adjusting rod controls the distance between the guide block and the right-angle bracket, thereby controlling the tightness of the wiring in that direction. By adjusting the tightness of the wiring in different directions, the convenience and flexibility of wiring tension adjustment are improved, preventing the wiring from becoming loose or crossing. Each fine-tuning body corresponds to a single or group of wiring, avoiding the problem of one-to-many movement in traditional cable ties. This ensures that the tightness of each wiring matches its specifications and installation requirements, improving the precision of the wiring. When wiring needs repair or replacement, there is no need to remove the cable ties or other one-time fixing structures; simply loosen the adjusting nut to move the fine-tuning body and loosen the wiring. This convenient operation significantly reduces the workload of disassembling and reassembling wiring during repairs, improving maintenance efficiency.

[0022] The cable tray 2 is equipped with multiple cable holders 4, each cable holder 4 having multiple first semi-circular grooves 5 for securing cables; the cable holder 4 includes a main body 10, as shown in the attached figure. Figure 3 As shown, the first semicircular groove 5 is provided on the upper surface of the main body 10. The two ends of the main body 10 have fixing holes 11, and screws 12 connected to the wiring board 2 are installed in the fixing holes 11. The main body and the wiring board are installed by screws, which ensures the stability of the main body installation and provides stable support for the lines clamped in the first semicircular groove. A positioning block 13 is installed on the wiring board 2. The positioning block is connected to the wiring board by welding. The lower surface of the end of the main body 10 has a positioning groove 14 that fits into the positioning block 13, as shown in the attached figure. Figure 4 As shown, screw 12 is connected to positioning block 13, and fixing hole is connected to positioning groove. The lower surface of the main body achieves a fit through the structure of block and inner groove, ensuring the accuracy of installation positioning and improving the convenience of main body installation. The fixing body 4 is equipped with a stand 6, and the stand 6 is equipped with an elastic wire clamping body 7. One end of the elastic wire clamping body 7 has multiple second semicircular grooves 8 corresponding to the first semicircular groove 5. The first semicircular groove 5 and the second semicircular groove 8 are combined to form a clamping groove 9 for fixing the line. When wiring in other areas of the wiring board, multiple lines are orderly arranged mainly through the cooperation of the fixing body and the elastic wire clamping body. During wiring, the line will first be clamped in the first semicircular groove, and then the second semicircular groove of the elastic wire clamping body will fit against the line. Multiple lines are thus orderly separated, achieving overall orderliness of multiple lines. The diameter of the clamping groove is larger than the wire diameter, allowing the wire within the groove to move axially without affecting the adjustment of the wire by the guide column and fine-tuning body on the right-angle frame. The upright frame 6 has a sliding groove 15, and one end of the elastic clamping body 7 is embedded in the sliding groove 15. The upright frame is connected to the main body via bolts. The elastic clamping body 7 includes a clamping main block 16, the upper end of which has a T-shaped portion 17 that fits into the sliding groove 15. Through the engagement of the T-shaped portion with the sliding groove of the upright frame, combined with the elastic return function of the spring, the clamping force is ensured to be stable and durable, preventing loosening after long-term use. One side of the clamping main block 16 has a flat portion 18 that passes through the sliding groove 15, and a spring 19 is installed on the flat portion 18, as shown in the attached diagram. Figure 5As shown, one end of the spring 19 is connected to the upright frame 6; the upper end of the upright frame 6 has a positioning pin 21, and the flat part 18 has a positioning protrusion 22. The end of the spring 19 is respectively sleeved on the positioning pin 21 and the positioning protrusion 22. The positioning structure is set to achieve the positioning of the spring and ensure the stability of the spring during compression and extension; the other side of the main wire clamping block 16 has a pressure block 20, and the second semi-circular groove 8 is set on the lower surface of the pressure block 20. The main clamping block 16 has a pair of symmetrically arranged ribs 23 on one side. When the main clamping block is pulled up, the operator can pinch the ribs, which can serve as force points, making the operation convenient and quick. The ribs can also improve the structural strength of the main clamping block. The bottom of the rib 23 has a dovetail groove 24, and the upper end of the pressure block 20 has a dovetail strip 25 that fits into the dovetail groove 24. The pressure block is detachably connected to the dovetail groove of the rib through the dovetail strip. When the second semicircular groove is worn or needs to be adapted to special specifications of the line, the pressure block can be replaced separately without replacing the entire wire fixing body or elastic clamping body, which extends the overall service life of the device and reduces the later replacement cost.

[0023] Working principle of this invention: Loosen the fixing button 334 at the upper end of the guide post 33 to release the shaft 331 from the locking state with the guide plate 31. At this time, the shaft 331 can slide freely along the guide groove 32, pushing each guide post to a preset position. Each line corresponds to one guide post, ensuring that the line can independently turn at the right angle bracket 30. After the initial route of the line is determined, tighten the fixing button 334 so that the lower surface of the fixing button is tightly attached to the upper surface of the guide plate 31. With the help of the positioning nut 332 at the end of the shaft, the guide post is locked in the guide groove 32. Then, the fine-tuning body 36 is fitted onto the transverse optical rod 34 and the transverse screw 35 via the fine-tuning block 361. The circuit is inserted into the groove of the guide block 362 below the fine-tuning block. The adjusting nut 37 on the transverse screw 35 is loosened, pushing the fine-tuning block to move axially along the transverse optical rod. By changing the distance between the guide block and the guide post 33, the adjusting rod 364 on the fine-tuning block 361 is rotated. Since the adjusting rod is threadedly connected to the fine-tuning block, the rotation of the adjusting rod will drive the guide block to make longitudinal (perpendicular to the transverse optical rod) displacement along the optical axis 363, and the circuit tightness reaches the desired level. After setting the requirements, tighten the adjusting nut 37 on the horizontal screw 35; the wire fixing body 4 precisely engages with the positioning block 13 on the wiring plate 2 through the bottom positioning groove 14, and then is locked with the positioning block 13 by screws 12 passing through the fixing holes 11 at both ends of the wire fixing body 4; during wiring, the operator pulls upward by pinching the ribs 23 on both sides of the elastic wire clamping body 7, so that the wire clamping main block 16 slides along the slide groove 15 of the stand 6 through the upper T-shaped part 17. At this time, the first semi-circular groove 5 on the wire fixing body 4 separates from the second semi-circular groove 8 under the pressure block 20 of the elastic wire clamping body 7, and the wire clamping main block 16 slides along the slide groove 15 of the stand 6 through the upper T-shaped part 17. After the fixed wires are placed one by one into the corresponding first semicircular groove 5, the rib plate 23 is released. The spring 19 on the flat part 18 is elastically reset under the limiting action of the positioning pin 21 and the positioning protrusion 22, which drives the wire clamping block 16 to move down, so that the second semicircular groove 8 and the first semicircular groove 5 are precisely spliced ​​to form the wire clamping groove 9. The continuous elastic force of the spring 19 achieves stable clamping of the wires, preventing the wires from becoming loose or tangled. During later maintenance, there is no need to cut any fixed structure. Just pull up the elastic wire clamping body 7 again to take out the wires. After maintenance is completed, the wires can be clamped again.
