Description

Technical Field

[0001] This application belongs to the field of wiring harness branching technology, specifically an automotive dashboard wiring harness with adjustable branching angle. Background Technology

[0002] Wiring harness branching refers to the branching of wires or conductors in an electrical or mechanical system to connect to different devices or modules for signal transmission or power distribution. In the automotive, home appliance, and communications industries, wiring harness branching plays a crucial role, effectively transmitting signals or current to multiple different locations.

[0003] Wiring harnesses typically consist of multiple cables, connectors, and fittings, ensuring the stability and safety of system operation. Special attention must be paid to the layout of the wiring harness, the robustness of the joints, and protective measures during design to avoid problems such as short circuits and poor contact.

[0004] However, traditional wire harnesses do not have adjustable branch angles, which is not conducive to wire harness management. Utility Model Content

The whole structure is a gradually tapering cone from the inlet end to the outlet end. The upper outer surface of the basic protective sleeve is fixed with equidistant limit rods, while the lower inner groove is connected to the corresponding adjacent basic protective sleeves by limit rods with larger intervals and deformation springs. The corresponding protrusions are stuck at the limit rods to deform the limit rods. After the corresponding basic protective sleeves are inserted, the angle is adjusted and they are inserted into the basic protective sleeve. The protrusions are fixed in the limit rods. The wire harness is placed by passing through the basic protective sleeve.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: In this application, the wire harness uses a base protective sleeve as a basic component. The overall shape is a gradually tapering cone from the inlet end to the outlet end. The upper outer surface of the base protective sleeve is fixed with equidistant limit rods, while the lower inner groove is connected to adjacent base protective sleeves by limit rods with larger intervals and deformation springs. The corresponding protrusions are locked at the limit rods, causing deformation of the limit rods.
