Electrical Connector Stranded Drain Wire Slot Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for multi-wire cables do not effectively address the separation and reliable fixation of stranded drain wires, which are essential for proper shielding and grounding, often requiring complex manipulation and tools.
Innovation Solution
Incorporating a tubular outer conductor with second slots to securely receive and fix stranded drain wires, utilizing magnetic materials for easy separation and bonding within these slots, and using a carrier body to support both cable-side and output-side contact elements for efficient assembly and shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stranded drain wires are separated and fixed to the connector using classical construction methods, then reliable grounding and shielding are achieved, but complex manipulation and additional tools are required
Solution Approach 1:
The outer conductor is segmented by forming slots that separate the drain wire reception area from the main connector body. This segmentation allows the drain wire to be independently guided and fixed without manipulating the entire connector assembly, reducing installation complexity while maintaining reliable grounding.
Solution Approach 2:
The slots in the outer conductor act as intermediary structures that facilitate the insertion and fixation of drain wires. These slots provide a dedicated pathway and positioning feature that simplifies the manipulation of drain wires during assembly, eliminating the need for complex tools or procedures while ensuring reliable electrical connection for grounding and shielding.
2Device complexity
If the outer conductor is designed without slots for drain wire reception, then the structure remains simple and compact, but stranded drain wires cannot be securely separated and fixed

AI summary
An electrical connector for a multi-wire electrical cable includes at least two cable-side electrical contact elements including associated terminals to each of which is connected a wire of the electrical cable, and at least two output-side electrical contact elements, from each of which projects an electrical connector element by which a mating connector is electrically connectable. A tubular outer conductor extends along a longitudinal direction from a cable-side end to an output-side end and encloses the cable-side and output-side contact elements. At least one stranded drain wire of the electrical cable contacts a shield of the electrical cable and is guided to the electrical connector separately from the wires of the electrical cable. The outer conductor has at least one second slot extending along the longitudinal direction of the outer conductor, and the drain wire is received in the second slot in the outer conductor.
