Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive wiring harness technology, specifically an automotive protective 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 an assembly that connects circuits by crimping copper contact terminals (connectors) with wires and cables, and then molding an insulator or adding an outer metal shell. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wire harnesses have a wide range of applications, including automobiles, home appliances, computer and communication equipment, and various electronic instruments.
[0003] A current publication (CN219642579U) discloses an automotive pressure-resistant telescopic wiring harness, comprising a cable with a connector on one side. A pressure-resistant component is provided on the outer wall of the cable. The pressure-resistant component includes a base pad adhered to the outer wall of the cable, a sleeve fixedly connected to the outer wall of the base pad, a spring fixedly connected to the top side of the sleeve, a support mesh on the top side of the spring, a telescopic rod slidably connected to the top side of the sleeve, an elastic pad on the top side of the telescopic rod, and a support mesh fixedly connected to the inner wall of the elastic pad. The elastic pad, support mesh, and base pad are all horizontally evenly distributed about the bisector of the cable, and the elastic pad is vertically evenly distributed about the outer wall of the cable. A binding strap is tied to the cable, horizontally evenly distributed about the outer wall of the cable, and a protective sleeve is fitted onto the outer wall of the cable. This design improves the pressure resistance of the cable.
[0004] While existing technologies have improved the compressive strength of wire harnesses to some extent, they cannot effectively separate the cables, making them prone to mutual interference. Therefore, we propose a protective wire harness for automobiles. Utility Model Content

A shielding layer is wrapped around the outside of the wrapping layer, and an outer sheath is wrapped around the outside of the shielding layer. The partition support frame is composed of a rubber strip, partition plates, and an arc-shaped plate. Multiple partition plates are evenly distributed on the outside of the rubber strip, and an arc-shaped plate is provided at the end of the partition plate away from the rubber strip.
