Description

Technical Field

[0001] This utility model belongs to the field of engine wiring conduits, and specifically relates to an engine wiring conduit assembly. Background Technology

[0002] Engine wiring conduits are pipes or conduits used in engine electrical systems to protect and guide wiring harnesses. Their primary function is to ensure the safe transmission of power or signals by wires and cables in the complex and harsh engine environment. They are typically made of high-temperature and corrosion-resistant materials, such as metals or special plastics, to withstand the high temperatures, vibrations, oil contamination, and chemical corrosion encountered during engine operation. However, the lack of modular splicing capabilities in engine wiring conduits presents significant drawbacks, primarily due to their rigid structure and insufficient adaptability. Firstly, non-modular wiring conduits offer extremely poor flexibility during installation and maintenance. Given the compact and complex layout of the engine compartment, fixed-length conduits struggle to accommodate wiring harnesses with varying routing or lengths, necessitating frequent cutting or bending during installation. This not only increases labor and material waste but also risks damaging the wiring harness insulation due to excessive bending, potentially leading to short circuits. Therefore, we aim to design an engine wiring conduit assembly to address this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an engine wiring conduit assembly to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: an engine wiring conduit assembly, comprising: a wiring conduit body, wherein an installation mechanism for fixing and supporting the wiring conduit body is provided on the outer side of the wiring conduit body;

[0005] The main body of the wiring conduit includes an inner flexible conduit with an outer protective layer on its outer side. External threaded connectors and internal threaded connectors are fixedly connected to the left and right ends of the inner flexible conduit, respectively. A wire separator is installed inside the inner flexible conduit, and the inner wall of the inner flexible conduit has a hollow structure filled with a heat insulation layer. Through modular design of the main body of the wiring conduit, wiring conduits of different lengths can be spliced ​​using the external and internal threaded connectors. The modular design allows for flexible bypassing of obstacles such as turbochargers and sensors, optimizing wiring paths and matching the wiring requirements of different vehicle models, avoiding the problems of traditional conduits being too long or too short.

[0006] In a preferred embodiment, the outer protective layer is a metal braided structure to improve the mechanical properties of the inner wiring hose and effectively prevent small animals such as rats from biting the inner wiring hose.

[0007] In a preferred embodiment, a sealing ring is provided on the outer side of the external threaded connector to prevent moisture intrusion and protect the internal wires from moisture corrosion.

[0008] In a preferred embodiment, the separator block is a soft and flexible thermoplastic elastomer structure.

[0009] In a preferred embodiment, the spacer block has several locking slots for locking and fixing wires.

[0010] As a preferred embodiment, the heat insulation layer is a glass wool structure with excellent fire resistance to prevent damage to internal wires caused by engine heat transfer.

[0011] In a preferred embodiment, the mounting mechanism includes two mounting blocks, each with a mounting hole at its lower end for fixing the mounting block, and a support rod fixedly connected to the upper surface of each mounting block, with a clamp fixedly connected to the upper end of each support rod.

[0012] In a preferred embodiment, washers are provided on the inner sides of both clamps to increase the friction between the clamps and the surfaces of the external and internal threaded joints, respectively.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:
