Cable Connector Support Structure to Prevent Insulator Crushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing cable assemblies, the insulator is prone to crushing and deformation during crimping, leading to increased near-end crosstalk and compromised signal transmission quality.
Innovation Solution
A cable assembly design that includes a support member with a support portion filling the gap between the insulator and the circuit board, preventing crushing and deformation of the insulator during crimping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable is crimped by a crimping device, then the cable is fixed to the circuit board, but the insulator is easily crushed and deformed due to the gap between the insulator and the circuit board
Solution Approach 1:
A support member is pre-installed on the circuit board at the location where the insulator will be positioned. This support member protrudes from the circuit board surface to fill the gap between the insulator bottom surface and the circuit board, providing cushioning support before the crimping operation occurs. During crimping, the support member prevents the insulator from being crushed or deformed by the crimping device, thereby resolving the contradiction between fixing reliability and insulator strength.
2Ease of manufacture
If the insulator is in a suspended state during crimping, then the crimping operation can be performed, but the insulator is easily crushed and deformed
Solution Approach 1:
The support member is installed on the circuit board before the cable crimping operation. It protrudes to fill the gap between the insulator and circuit board, providing structural support during crimping. This allows the crimping operation to proceed easily while preventing insulator deformation, thus resolving the contradiction between ease of manufacture and manufacturing precision.
3Productivity
If the insulator is crushed and deformed, then the crimping process is completed, but near-end crosstalk increases and signal transmission quality deteriorates
Solution Approach 1:
The support member is positioned on the circuit board before crimping to fill the gap and support the insulator. During the crimping process, it prevents insulator crushing and deformation, thereby preventing near-end crosstalk and maintaining signal transmission quality. This resolves the contradiction between productivity and reliability by enabling complete crimping while preserving signal integrity.
