Communication Connector Wire Holding Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication quality is reduced due to changes in intervals between wires, which act as impedance changing points, causing signal reflection, especially in vehicles where vibrations can further disrupt wire arrangements.
Innovation Solution
A communication connector design featuring a wire holding member with grooves to maintain consistent wire intervals, a shield case to restrict the wire holding member's movement, and a configuration that allows for easy assembly and vibration resistance, ensuring stable wire positioning even in vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wires are used instead of metal bars as conductors, then flexibility and ease of connection are improved, but wire intervals change at deflected positions causing impedance changes and signal reflection
Solution Approach 1:
A wire holding member is introduced as an intermediary component between the wires and the housing. This holding member includes positioning portions that contact the wires and restrict their movement, thereby maintaining constant wire intervals even when wires are deflected, preventing impedance changes and signal reflection while preserving the flexibility of using wire conductors
Solution Approach 2:
The wire holding member changes the physical state of wire positioning from variable (deflected) to fixed (constant interval). By introducing the holding member with specific positioning structures, the wire intervals are maintained at designed values, preventing impedance variations and ensuring stable signal transmission
2Ease of manufacture
If wire intervals are allowed to change for flexibility, then ease of installation is improved, but impedance changing points are created causing signal reflection
Solution Approach 1:
The wire holding member serves as a mediator that ensures precise wire interval positioning during installation. It includes positioning portions that guide and fix wire positions, allowing easy installation while maintaining manufacturing precision through the mechanical constraint provided by the holding member's structure
Solution Approach 2:
The wire holding member is pre-formed with specific positioning portions and groove patterns that predetermined the correct wire intervals. During installation, wires are simply placed into the pre-designed grooves, which automatically position them at the correct intervals, combining ease of installation with precision
3Reliability
If wire holding structures are added to maintain constant intervals, then communication quality is improved, but device complexity increases
Solution Approach 1:
The wire holding member is merged with the housing structure, where the holding member is positioned within and integrated into the housing. This combining approach maintains constant wire intervals for improved communication quality while avoiding the need for completely separate, complex wire management systems
Solution Approach 2:
The wire holding member uses a relatively simple, thin-walled structure with integrated positioning portions and grooves. This design maintains wire interval consistency without adding significant bulk or complexity to the overall connector structure, achieving reliability improvement with minimal complexity increase
