AI Technical Summary

Technical Problem

Existing vehicle devices face challenges in establishing a stable and liquid-tight electrical connection between a printed circuit board housed within a device and a fan located outside the housing, with issues such as cable movement, undesirable tolerances, and potential liquid ingress through cable openings.

Method used

A vehicle device design featuring a cable guide element adjacent to the cable opening, guiding the cable from the housing's lowest point to a higher position, utilizing a raised protrusion or plateau to minimize internal width and form a bottleneck, and incorporating an outer wall sloping downward to prevent liquid ingress, ensuring precise and dense cable laying.

Benefits of technology

The design achieves stable, precise cable placement, minimizes cable movement, and effectively prevents liquid ingress, enhancing the electrical connection's reliability and durability.
