Shielded Connector With Divided Inner Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of shielded connectors becomes inefficient when the insulative outer sheath is stripped short, requiring precise alignment and insertion of multiple terminals, which can lead to impedance mismatch and interference between wires.
Innovation Solution
A shielded connector with a divided inner housing that allows terminals to be inserted in smaller groups, reducing stiffness and interference, and enabling easier insertion by allowing directional adjustment and sequential insertion of terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insulative outer sheath is stripped short to avoid impedance mismatch, then transmission performance is improved, but the stiffness of the connecting part increases making terminal insertion difficult
Solution Approach 1:
The inner housing is divided into multiple independent housing units, each accommodating a subset of terminals. This segmentation allows terminals to be inserted in smaller groups rather than all at once, reducing the stiffness and interference issues when the sheath is stripped short. Each housing unit can be assembled independently with fewer terminals, making the insertion process easier while maintaining the short stripped length for good transmission performance.
2Manufacturing precision
If multiple terminals are inserted simultaneously to maintain alignment, then insertion precision is improved, but the operation becomes inefficient and time-consuming
Solution Approach 1:
The terminal accommodating housing is divided into multiple independent housing units that can be assembled separately. Each unit contains fewer terminals that can be inserted simultaneously, maintaining alignment precision while reducing the overall complexity and time required compared to inserting all terminals at once. The modular units can then be combined to form the complete connector.
Solution Approach 2:
The housing is pre-divided into multiple independent units before the terminal insertion process. This preliminary segmentation allows operators to prepare and insert terminals into smaller groups in advance, rather than attempting to align and insert all terminals simultaneously, thereby improving assembly efficiency without sacrificing precision.
3Ease of operation
If the inner housing is divided into smaller terminal groups, then terminal insertion becomes easier, but the device complexity increases
Solution Approach 1:
The inner housing is segmented into multiple independent housing units, each capable of accommodating a subset of terminals. This segmentation simplifies the terminal insertion process by reducing the number of terminals that need to be handled simultaneously, making insertion easier. The modular design actually reduces operational complexity despite adding structural elements, as each unit can be assembled and verified independently.
