Conductor Rail Cage for Lighting System Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular lighting systems face issues with improper handling of components leading to incorrect fitting and electrical malfunctions during assembly, particularly due to damage of protruding conductor ends during transport.
Innovation Solution
A conductor cage made of insulating material is attached to the end face of conductor holders, covering protruding conductor ends and providing protection against mechanical damage, with features like through-openings, conical funnels, snap hooks, and electromechanical connectors ensuring correct alignment and electrical connection without protrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductor ends protrude beyond the conductor holder end face for connection purposes, then electrical connection between conductor holders is enabled, but the protruding conductor ends are easily damaged during transport
Solution Approach 1:
The conductor cage is attached to the conductor holder before the conductor ends protrude, providing pre-protection against mechanical damage during transport and handling. This preliminary protective measure ensures the conductor ends remain intact until the connection phase.
Solution Approach 2:
The conductor cage acts as an intermediary protective element between the conductor ends and external mechanical hazards. It provides a protective barrier that prevents direct contact between the vulnerable conductor ends and damaging external forces during transport.
2Object-affected harmful factors
If a protective device is added to cover the conductor ends, then mechanical damage is prevented, but the device complexity increases
Solution Approach 1:
The conductor cage serves multiple functions simultaneously: it protects conductor ends from mechanical damage, provides structural support during assembly, and maintains proper alignment of conductors. This multi-functionality reduces the need for separate protective components.
Solution Approach 2:
The conductor cage is designed as a thin-walled protective structure that provides adequate protection while minimizing added complexity and material usage. The cage's streamlined design allows it to be integrated into the existing conductor holder assembly without significant structural modifications.
3Object-affected harmful factors
If the conductor cage is integrated into the conductor holder, then protection is provided, but retrofitting existing systems becomes difficult
Solution Approach 1:
The conductor cage is designed as a separate, modular component that can be independently attached to the conductor holder. This segmentation allows the cage to be added to existing conductor holders without redesigning the entire assembly, enabling easy retrofitting of current systems.
Solution Approach 2:
The conductor cage can be pre-assembled onto conductor holders during manufacturing, allowing existing field-installed systems to be upgraded by simply replacing individual conductor holder assemblies. This preliminary assembly approach facilitates gradual system updates without complete system replacement.

AI summary
The invention relates to a busbar for functional inserts of a lighting system, comprising: elongated mounting rails which form a receiving space for the functional inserts, and elongated conductor holders which are arranged in the mounting rails and which hold a number of electrically conductive conductors aligned parallel to each other, which can be contacted by current collectors of the functional inserts, wherein the conductor holders can be coupled to each other at their end faces, so that the conductors of the two conductor holders are electrically connected to each other in pairs, wherein a conductor cage is arranged in the end-face coupling area of the two conductor holders, wherein the conductor cage is attached to the conductor ends of one of the two conductor holders at their end faces and covers the conductor ends to a length by which they protrude beyond an end face of the conductor holder.
