Sealed Stranded Grounding Wire Assembly for Moisture Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunications enclosures face challenges in effectively grounding internal components to protect against power surges and electrical charges, particularly in maintaining a sealed environment to prevent moisture and contaminant intrusion.
Innovation Solution
A grounding wire assembly comprising a stranded wire with a conductive core and insulating jacket, combined with a solid wire and tubular conductive member, forms an electrical connection and seal using heat shrink tubing to prevent contamination and ensure grounding, which is routed through a gel sealing block in telecommunications enclosures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stranded wire with insulating jacket is used for grounding, then flexibility and ease of routing are improved, but the risk of moisture and contaminant intrusion through the stranded structure increases
Solution Approach 1:
A solid core wire is introduced as an intermediary element inside the stranded wire assembly. This solid core provides a continuous, non-porous pathway that prevents moisture and contaminants from penetrating through the stranded structure, while the outer stranded layer maintains flexibility for easy routing. The solid core acts as a mediator between the flexibility requirement and the sealing requirement.
Solution Approach 2:
The grounding wire assembly uses a composite structure combining stranded conductive material with a solid core. The stranded outer layer provides flexibility and ease of installation, while the solid inner core provides moisture resistance and environmental sealing. This composite approach allows both contradictory requirements to be satisfied simultaneously.
2Reliability
If grounding wires are routed through gel sealing blocks, then environmental sealing is improved, but the complexity of installation and maintenance increases
Solution Approach 1:
The solid core grounding wire assembly serves multiple functions: it provides electrical grounding, acts as a moisture barrier, and simplifies installation through its pre-formed solid structure. By combining these functions into a single assembly, the system reduces overall complexity while maintaining reliable environmental sealing through the gel block.
3Reliability
If sealed grounding assemblies are used, then protection from power surges and electrical charges is improved, but the cost and complexity of the grounding system increases
Solution Approach 1:
The invention merges the grounding function with the sealing function into a single integrated assembly. The solid core wire with insulating jacket and outer stranded layer combines electrical conductivity, environmental sealing, and surge protection capabilities in one component, reducing the need for separate sealing measures and simplifying the overall grounding system.

AI summary
A sealed stranded wire assembly includes one or more stranded wires. The one or more stranded wires includes a solid portion formed on or attached to the length of the one or more stranded wires. The solid portion prevents liquid, dust, or other contaminants from traveling along the length of the one or more stranded wires through voids within the one or more stranded wires.
