Differential Pair Connector Housing for Cable Expansion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In connectors with parallelly routed wires, differential pair cables can expand outward, leading to communication failures.
Innovation Solution
A connector design featuring a terminal module with a pair of terminal fittings connected to a differential pair cable, housed in a module with expansion preventing walls that sandwich the cable from the outer sides to prevent expansion, and a strain relief portion to manage cable tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plurality of wires are routed in parallel in a housing, then the wiring structure is simple and easy to manufacture, but the differential pair cable may expand outward in the array direction causing communication failure
Solution Approach 1:
The patent applies local quality by providing expansion preventing walls at specific locations where the differential pair cable passes through the housing. These walls are positioned only in the array direction where expansion occurs, rather than constraining the cable in all directions. This localized constraint maintains communication reliability while preserving the overall simplicity of the parallel wiring structure.
Solution Approach 2:
The housing is segmented into multiple chambers with expansion preventing walls dividing the space through which the differential pair cable passes. This segmentation creates discrete constrained zones that prevent cable expansion in the array direction while allowing the rest of the wiring structure to remain simple and flexible.
2Reliability
If expansion preventing walls are added to sandwich the differential pair cable, then communication failure is suppressed, but the device complexity increases
Solution Approach 1:
The expansion preventing walls serve multiple functions: they prevent cable expansion in the array direction, provides structural support for the housing, and define the boundaries of cable routing chambers. By making these walls multi-functional, the patent improves communication reliability without adding dedicated separate components that would increase device complexity.
Solution Approach 2:
The expansion preventing walls are merged with the housing structure itself rather than being separate attachments. The walls are formed as integral parts of the housing chambers, combining the cable constraint function with the housing's structural and routing functions, thereby minimizing the increase in device complexity.
