Description
Technical Field
[0001] This utility model relates to a low-voltage power metering box with wire harness fixing function, belonging to the field of power facility technology. Background Technology
[0002] A low-voltage electricity metering box is a specialized device used for electricity metering and management in low-voltage power distribution systems. It is typically installed on the user side (such as in residential, industrial, and commercial locations) to accurately measure and record electricity consumption. Its core components include an electricity meter, circuit breaker, instrument transformer (if required), wiring terminals, and protective devices. The casing is usually made of flame-retardant and corrosion-resistant materials and features anti-theft, dustproof, and moisture-proof designs.
[0003] Authorization announcement number (CN 219179478 U) discloses a low-voltage electricity metering box, belonging to the field of electrical facility technology. It includes an outer casing and a door, with the door hinged to the front end of the outer casing. The door has a viewing window, and multiple heat dissipation vents are provided on both sides of the outer casing. A top cover is installed on the top of the outer casing, and a fixing frame is fixedly connected to the bottom of the top cover. Locking components, including screws and locking bolts, are provided on both sides of the fixing frame. A loading plate is fixedly connected to the bottom of the top cover, and the top of the outer casing matches the fixing frame, which is sleeved on the outside of the top of the outer casing. This utility model designs the low-voltage electricity metering box with a split structure, allowing the parts for installing electricity meters and circuit breakers to be disassembled as a whole. When maintenance is required, the entire box can be removed, freeing personnel from spatial constraints and facilitating the maintenance of various electrical components.
[0004] However, the lack of wire harness fixing measures during the use of the above technology leads to messy internal wires. Loose cables may cause poor contact at the terminals, resulting in power metering errors or even power outages. Unfixed wires may have their insulation layer damaged under long-term vibration or external force, increasing the risk of short circuits, arc discharges and fires, causing inconvenience to daily inspection and maintenance, and increasing the probability of misoperation.

[0032] Example 1
[0033] like Figure 1-7 As shown, this utility model embodiment provides a low-voltage power metering box with wire harness fixing function, including:
[0034] Mounting assembly 100 includes a housing 101. The bottom of the housing 101 has multiple wire holes. An assembly plate 104 is fixedly mounted on the inner side of the housing 101 by bolts. An assembly rack 105 is fixedly mounted on the front side of the assembly plate 104 by bolts.
[0035] The fixing assembly 200 includes a fixing plate 201 and a cover plate 203. There are two fixing plates 201 and two cover plates 203, and the two cover plates 203 are located on top of the two fixing plates 201. Multiple equally spaced wire harness grooves 202 are opened on the inner side of the cover plate 203. Multiple positioning rods 204 are fixedly installed on the bottom of the cover plate 203, and the number and position of the multiple positioning rods 204 and the wire harness grooves 202 are matched. Connecting rods 205 are fixedly installed on the left and right sides of the bottom of the two cover plates 203. Connecting blocks 206 are fixedly installed on the lower end of the connecting rods 205, and the connecting rods 205 and the connecting blocks 206 are located on the left and right sides of the inner cavity of the fixing plate 201.
[0036] A first rigid spring 207 is fixedly installed on both the left and right sides of the inner cavity of the two fixing plates 201. The lower end of the first rigid spring 207 is fixedly connected to the top of the connecting block 206, and the first rigid spring 207 is located outside the connecting rod 205. Multiple through holes 208 are opened at equal intervals on the top of the fixing plate 201 and above the wire harness groove 202. The positioning rod 204 extends through the through holes 208 to the inner side of the wire harness groove 202.
[0037] By setting the fixing component 200, the wire harness can be fixed to ensure that the wiring inside the box is neat and orderly, effectively preventing the wires from loosening or shifting, reducing the wear of the wire harness sheath and the risk of short circuit, improving electrical safety, reducing fire hazards, improving heat dissipation, and extending the service life of the equipment. In addition, it also facilitates daily maintenance and troubleshooting, and improves maintenance efficiency.
[0038] Example 2
[0039] like Figure 1-7 As shown, in one embodiment, connecting brackets 209 are fixedly installed on the left and right sides of the bottom of the two fixed plates 201. A slider 212 is provided on the inner side of the connecting bracket 209. Insert rods 213 are fixedly installed on the front and rear sides of the slider 212. Multiple equally spaced slots 214 are opened on the left and right sides of the inner cavity of the box 101, and the insert rods 213 extend to the inner side of the slots 214. Guide rods 210 are fixedly installed on the inner side of the two connecting brackets 209. The slider 212 is slidably connected to the surface of the guide rod 210. Guide rails 215 are bolted to the left and right sides of the inner side of the box 101. Guide grooves 216 are opened on the left and right sides of the fixed plate 201.

The top of the rainproof canopy 102 is sloping. A box door 103 is movably connected to the front side of the box 101 through a hinge.
[0040] Tension is provided by the second rigid spring 211, which drives the slider 212 and the insertion rod 213 to move outward, so that the insertion rod 213 extends to the inside of the slot 214, thereby fixing the position of the fixing plate 201. The guide rod 210 can improve the stability of the slider 212 during movement, and the guide rail 215 can play a guiding role to prevent the fixing plate 201 from deviating during sliding.
[0041] In operation, this utility model is ready for use after assembling electrical components onto the surfaces of the assembly plate 104 and the assembly frame 105. During use, when connecting the wiring harness, the harness is passed through the wire hole at the bottom of the housing 101, and the cover plate 203 is pulled upwards, causing the positioning rod 204 to move upwards. After the harness passes through the corresponding wire harness groove 202, the cover plate 203 can be released. At this point, the first rigid spring 207, having lost external pressure, will rebound due to its own tension, causing the connecting rod 205 and the connecting block 206 to move downwards, connecting... As rod 205 moves, it causes cover plate 203 to move downward, so that positioning rod 204 fits against wire harness and fixes the wire harness. When the position of fixing plate 201 needs to be adjusted according to different usage requirements, slider 212 can be pulled outward to adjust the height of fixing plate 201. After adjusting to the appropriate position, slider 212 can be released, and tension provided by second rigid spring 211 drives slider 212 and insertion rod 213 to move outward and extend to the inside of slot 214, thereby completing the fixation of fixing plate 201.
[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
