Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, specifically a flame-retardant automotive wiring harness. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits. Without wiring harnesses, there would be no automotive circuits. A wiring harness is a component that connects circuits by crimping copper contact terminals (connectors) with wires and cables, and then molding an insulator or adding a metal shell. The wiring harnesses are bundled together to form a circuit connection. The body wiring harness connects the entire body and is generally H-shaped.

[0003] In response, Chinese patent application number CN202122030786.X discloses a flame-retardant wiring harness sheath for new energy vehicles, comprising a protective sleeve, a limiting ring on the outer side of the protective sleeve connected to the protective sleeve, a slider inside the limiting ring located within the limiting ring and in contact with the protective sleeve, a magnet on the outer side of the slider connected to the slider, and a fire-resistant layer inside the protective sleeve. This flame-retardant wiring harness sheath for new energy vehicles provides protection for the wiring harness. Compared to ordinary wiring harness sheaths, this sheath offers advantages such as the ability to protect multiple wiring harnesses, flame retardancy, and positional fixation of the wiring harnesses. It solves the problem that existing wiring harness sheaths cannot fix the position of the wiring harnesses, only provide simple protection, and lack flame-retardant functionality.

[0004] The device uses a protective sleeve to cover the outside of the wire harness, and multiple protective layers of materials are set on the outside of the protective sleeve to ensure the protection of the wire harness. However, most existing wire harnesses are finished products, and their two ends are mostly fixed with connectors. The size of the connectors is larger than the size of the wire harness. Therefore, when the wire harness is inserted into the protective sleeve, the connectors at both ends cannot pass through smoothly, which makes the use of the device obviously limited and inconvenient for users.

[0005] Therefore, in order to solve the above problems, a flame-retardant automotive wiring harness is proposed. Summary of the Invention

[0013] Preferably, one end of the connecting frame is fixedly connected to the second fixing block.

[0014] Preferably, the bottom end of the screw is threadedly connected to the first fixing block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting two sets of first fixing blocks and two sets of second fixing blocks, the two ends of the two sets of arc-shaped tubes can be fixed to the outside of the connectors at both ends of the line body, so that the arc-shaped tubes are located on the outside of the line body and can support the line body from the outside. The two sets of arc-shaped tubes are connected to each other through connecting pipes and connecting grooves. Flame retardant liquid can be injected inside. When an external fire occurs, the flame retardant liquid inside the arc-shaped tubes can drip onto the surface of the line body, reducing the damage of the fire to the line body.

[0016] This utility model features a protective structure. Two sets of arc-shaped tubes are installed on the upper and lower sides of the line body, respectively. The two sets of arc-shaped tubes are then fitted together, with the connecting pipes and connecting grooves on the two sets of arc-shaped tubes interlocked, allowing the two sets of arc-shaped tubes to connect and communicate internally. Simultaneously, the two sets of arc-shaped tubes can be fitted onto the outside of the line body, providing external support. Two sets of first fixing blocks are fitted onto the outside of the two sets of connectors, and two sets of second fixing blocks are fitted onto the side of the connectors away from the first fixing blocks. The locking blocks on the first and second fixing blocks can be inserted into the outside of the locking grooves. Then, by rotating the screws, the locking blocks and second fixing blocks are connected and fixed, ensuring stable installation on the outside of the connectors. This makes the installation of the device convenient. Finally, flame-retardant liquid can be injected into the two sets of arc-shaped tubes through the injection port. In the event of an external fire, the flame-retardant liquid inside the arc-shaped tubes can drip onto the surface of the line body, reducing the damage to the line body from the fire.

A sealing gasket is provided at the connection between the connecting tubes 24 and the connecting grooves 25 to ensure the sealing of the connection between the two sets of arc-shaped tubes 23 and prevent the internal flame retardant liquid from leaking out.

[0030] Furthermore, one end of the connecting frame 26 is fixedly connected to the second fixing block 28. The connecting frame 26 can fix the arc tube 23, ensuring the ease of splicing the two sets of arc tubes 23.

[0031] Furthermore, the bottom end of the screw 29 is threadedly connected to the first fixing block 21. The first fixing block 21 and the second fixing block 28 can be connected and fixed by the screw 29 to prevent them from falling apart.

[0032] Working principle: During installation, two sets of arc-shaped tubes 23 are installed on the upper and lower sides of the line body 1, respectively. Then, the two sets of arc-shaped tubes 23 are fitted together, and the connecting tubes 24 and connecting grooves 25 on the two sets of arc-shaped tubes 23 are inserted into each other, so that the two sets of arc-shaped tubes 23 are connected and internally communicated. At the same time, the two sets of arc-shaped tubes 23 can be sleeved on the outside of the line body 1, which can support the line body 1 on the outside. Two sets of first fixing blocks 21 are respectively sleeved on the outside of the two sets of connectors 11, and two sets of second fixing blocks 28 are sleeved on the connectors 11 away from the first fixing blocks 21. On one side of the fixing block 21, the locking block 22 on the first fixing block 21 and the second fixing block 28 can be inserted into the outside of the slot 12. Then, the screw 29 is rotated to connect and fix the locking block 22 and the second fixing block 28, so that the locking block 22 and the second fixing block 28 are stably installed on the outside of the connector 11, making the installation of the device convenient. Then, flame retardant liquid can be injected into the two sets of arc tubes 23 through the liquid injection port 27. When an external fire occurs, the flame retardant liquid in the arc tube 23 can drip onto the surface of the line body 1, reducing the damage of the fire to the line body 1.
