Innovation Solution
A cable connector assembly featuring a plug with insulative housing and conductive terminals, a crimping member with a crimping ring and reinforcement, and a metal shell, which simplifies the structure and enhances stability by grounding the reinforcement through ground terminals, ensuring electrical connection and reducing signal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable connector assembly uses multiple separate components (first metal shell, second metal shell, cage, PCB) to ensure structural stability and electrical connection, then the reliability of electrical connection is improved, but the device complexity and overall size increase, making miniaturization difficult
Solution Approach 1:
The patent combines multiple separate components (first metal shell, second metal shell, cage, and PCB) into a single integrated metal shell structure. This metal shell simultaneously provides mechanical support, electrical connection, and shielding functions that were previously distributed across multiple components, thereby reducing device complexity and enabling miniaturization while maintaining connection reliability
Solution Approach 2:
The integrated metal shell serves multiple functions: it acts as a structural support frame, provides electrical connection paths through its conductive walls, offers electromagnetic shielding, and serves as a mounting structure for the plug and cable assembly. This multi-functionality eliminates the need for separate dedicated components for each function
2Stability of the object's composition
If a cable connector assembly uses multiple separate components to ensure structural stability, then the stability is improved, but the overall size increases and miniaturization becomes difficult
Solution Approach 1:
The patent integrates multiple structural components into a single compact metal shell that maintains structural stability through its rigid construction and strategic support points. The metal shell's integrated design eliminates gaps and alignment issues between separate components while reducing overall assembly volume
Solution Approach 2:
The plug assembly is nested within the metal shell, and the cable is routed through the metal shell structure. This nested arrangement allows components to occupy overlapping or adjacent spaces efficiently, minimizing the overall volume of the connector assembly while maintaining structural integrity
3Reliability
If the cable connector uses a complex multi-component structure, then electrical connection reliability is improved, but the manufacturing complexity and yield issues increase
Solution Approach 1:
The integrated metal shell reduces the number of parts that need to be manufactured, assembled, and quality-checked. By combining multiple functions into one component, the manufacturing process is simplified, assembly steps are reduced, and potential failure points from multiple connection interfaces are eliminated, thereby improving both manufacturability and yield
