Description

Technical Field

[0001] This utility model relates to the field of low-voltage power supply wire technology, specifically a lightweight low-voltage power supply wire. Background Technology

[0002] Low-voltage power supply cables refer to wires and cables with a rated voltage of 1kV and below. Their core characteristics include simple structure (composed of conductor, insulation layer, and sheath), diverse materials (such as polyvinyl chloride and cross-linked polyethylene), and wide range of applications. The conductor is mostly made of copper or aluminum with a moderate cross-sectional area. The insulation layer and sheath respectively serve to isolate current and protect the cable.

[0003] When using current low-voltage cables, the installation process requires the cooperation of multiple components, which makes installation more complicated and affects efficiency. At the same time, the strength of a single cable structure is insufficient, and increasing the strength will result in a heavier cable. Utility Model Content

When using current low-voltage cables, the installation of the cable requires the cooperation of multiple components, which makes the installation operation more troublesome and affects the installation efficiency. At the same time, the strength of a single cable structure is insufficient, and increasing the strength will make the cable heavier.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight low-voltage power supply cable, comprising a main support block, a snap-fit ​​bottom block symmetrically fixedly disposed on the bottom surface of the main support block, snap-fit ​​side blocks symmetrically snapped onto both sides of the snap-fit ​​bottom block, a clamping bottom plate symmetrically mated to the bottom surface of the main support block, a clamping screw horizontally inserted into one end of the main support block, a sealing cover plate horizontally snapped onto the top surface of the main support block, a mating top groove symmetrically formed on the top surface of the sealing cover plate, a snap-fit ​​bottom block symmetrically fixedly disposed on the bottom surface of the sealing cover plate, and a through groove formed on the side of the snap-fit ​​bottom block. The main support block has symmetrically fixed snap-fit ​​inclined blocks at both ends. The top surface of the main support block has a horizontally and evenly snap-fitted protective outer layer. The top surface of the main support block has evenly opened wire-clamping grooves. The bottom surface of the main support block has a horizontally opened bottom mating groove. The top of the clamping base plate has a fixed mounting top block. The inner side of the bottom mating groove has a snap-fit ​​inner block. The bottom end of the snap-fit ​​inner block has an installation bottom opening. The side of the snap-fit ​​inner block has a horizontally opened mating screw hole. The inner side of the protective outer layer has a horizontally fixed isolation sponge layer. The inner side of the isolation sponge layer has a fixed main wire body.

[0006] Preferably, there are four snap-fit ​​bottom blocks, and the four snap-fit ​​bottom blocks are all set with the same specifications and dimensions. The four snap-fit ​​bottom blocks are symmetrically fixed to each other on the bottom surface of the main support block near the four corners.

[0007] Preferably, there are two clamping base plates, which are arranged in parallel with each other. The top ends of the clamping base plates are joined together at the bottom opening end of the bottom mating groove. The extension end of the clamping screw is fixedly provided with a cap structure, and the clamping screw is horizontally inserted into the inner side of the bottom mating groove.

[0008] Preferably, the sealing cover is horizontally snapped onto the top opening of multiple locking grooves, and the arrangement of the top grooves is consistent with the arrangement of the locking bottom blocks. The bottom ends of the locking bottom blocks are correspondingly snapped onto the inner sides of adjacent mating top grooves. There are two locking bottom blocks, and the two locking bottom blocks are parallel and symmetrically fixed to each other on the bottom surface of the sealing cover near both ends.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This lightweight low-voltage power supply cable features a multi-point fixing structure for daily use. The sealing cover and main support block are connected via a snap-fit ​​bottom block, a snap-fit ​​inclined block, and a matching top groove, further enhancing the overall structural stability. This effectively prevents the cable from loosening or being damaged due to shaking or external forces during use, ensuring power supply stability. The outer protective layer is made of corrosion-resistant and tensile-resistant material, resisting external environmental corrosion and pulling, extending the cable's lifespan. The inner insulating sponge layer acts as a buffer and isolation layer, reducing the impact of external vibrations and shocks on the main cable body, while also preventing mutual interference between different cables and improving signal transmission quality. The connections between components are primarily snap-fit ​​and screw-fit, requiring no complex tools or professional skills. During installation, simply assemble and fix each component sequentially, significantly shortening installation time, improving work efficiency, and reducing installation costs. This also facilitates the orderly placement and management of the main cable body. This layout not only makes the cables look neat and aesthetically pleasing, but also facilitates later maintenance and repair. When a problem occurs with a cable, it can be quickly located and dealt with, reducing the difficulty and time of maintenance. Attached Figure Description
