Terminal Module with Segmented Holding Members for Shielded Cable Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shielded cable connectors expose terminal tips, leading to deformation during assembly and potential noise interference due to improper stripping or untwisting of shield layers, and lack effective protection against contact with outer conductor shells.
Innovation Solution
A terminal module with divided first and second terminal holding members, where the second member covers and protects the terminal tip, allowing for shorter stripping or untwisting dimensions and preventing deformation by locking the terminal in place within the outer housing, reducing noise influence and frequency characteristic deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the terminal holding member is designed as a single integrated structure, then the device complexity is reduced, but the terminal tip cannot be protected from deformation during assembly
Solution Approach 1:
The terminal holding member is divided into two separate components: a first terminal holding member that holds the terminal body, and a second terminal holding member that covers and protects the terminal tip. This segmentation allows each component to perform its specific function independently, protecting the terminal tip from deformation while maintaining manageable device complexity.
2Ease of operation
If the terminal tip is exposed for connection, then the connection accessibility is improved, but the terminal tip is susceptible to deformation from external contact
Solution Approach 1:
The second terminal holding member is designed to cover and protect the terminal tip in advance before the connection process begins. This preliminary protective action prevents external contact and deformation during assembly and handling, while still allowing the terminal tip to be accessed for connection when needed.
3Ease of manufacture
If the shield layer is stripped by a long dimension to accommodate terminals, then the terminal accommodation is facilitated, but the noise interference increases
Solution Approach 1:
The terminal is accommodated by inserting it from a direction intersecting the extending direction of the terminal (perpendicular insertion), rather than from the end. This dimensional change allows the terminal to be positioned correctly without requiring excessive stripping length of the shield layer, thereby reducing noise interference while maintaining ease of manufacture.

AI summary
A terminal module M1 is to be accommodated into an outer housing 30, and includes male terminals 20 to be connected to ends of signal wires 11, a first terminal holding member 61 including accommodation recesses 78 for accommodating the terminals 20 inserted in a direction intersecting an extending direction of the terminals 20 with tip parts 21 of the terminals 20 projecting, and a second terminal holding member 65 to be assembled with the first terminal holding member 61. The second terminal holding member 65 is relatively movable toward ends of the signal wires 11 from a terminal tip protection position where the second terminal holding member 65 covers tip parts 21 of the terminals 20 projecting from the first terminal holding member 61.
