Twisted-Pair Connector Routing Groove for Signal Wire Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In differential signal transmission using twisted pair cables, the improper insertion of terminal portions into connectors can lead to widened intervals between wires, degrading transmission characteristics.
Innovation Solution
A connector design featuring a terminal module with a routing groove to accommodate wire exposed portions, guiding portions to align wires, and an accommodation recess to facilitate proper alignment and insertion, minimizing the separation of signal wires and maintaining optimal transmission characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wires are untwisted to insert terminal portions separately, then the terminal portions can be properly inserted, but the interval between the wires is widened
Solution Approach 1:
A guide member is introduced as an intermediary component between the twisted pair cable and the connector body. This guide member includes a guide groove that receives and guides the wire exposed portions, ensuring they are properly positioned during insertion. The guide member acts as a mediator that facilitates the insertion operation while simultaneously maintaining the wire interval, thus resolving the contradiction between ease of operation and manufacturing precision.
2Ease of operation
If the wires are untwisted over the entire length of terminal portions, then separate insertion is enabled, but transmission characteristics are degraded
Solution Approach 1:
The guide member is divided into multiple functional segments: a guide groove segment for receiving and positioning the wire exposed portions, a holding segment that maintains the wire interval, and a connection segment that links to the connector body. This segmentation allows each part to perform its specific function optimally - enabling separate insertion while preserving transmission characteristics through proper wire positioning.
3Productivity
If the terminal portions are simultaneously inserted, then the operation is simpler, but improper insertion occurs
Solution Approach 1:
The guide member serves as a mediator that enables simultaneous insertion while ensuring proper positioning. The guide groove is designed to receive both wire exposed portions simultaneously, and the guide structure inherently maintains the correct interval between wires during the insertion process. This eliminates the need for sequential insertion operations while preventing improper insertion, thus resolving the contradiction between productivity and ease of operation.
