Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of physically and electrically connecting a conducting wire of a cable to a center contact in a connector is time-consuming, costly, and unreliable, particularly in coaxial cable assemblies.
Innovation Solution
A connector design featuring an outer shield, a holder, and a center contact where the center contact is elastically deformed by the conducting wire during insertion, allowing for simultaneous physical and electrical connection without a separate fastening process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate fastening process is used to connect the conducting wire to the center contact, then the connection reliability is improved, but the assembly time and complexity increase
Solution Approach 1:
The patent combines the electrical connection function and mechanical fastening function into a single integrated center contact structure. The center contact simultaneously establishes electrical contact with the conducting wire and secures it through elastic deformation, eliminating the need for separate fastening operations while maintaining connection reliability
Solution Approach 2:
The center contact is designed to automatically secure the conducting wire through its own elastic deformation during insertion. The structure self-adjusts and self-locks the conducting wire in place through the elastic recovery of the center contact material, without requiring external fastening mechanisms or additional assembly steps
2Stability of the object's composition
If a separate fastening process is used to connect the conducting wire to the center contact, then the connection stability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges multiple functions (electrical contact, mechanical support, and fastening) into a single center contact component. This reduces the total number of parts and assembly operations required, thereby lowering manufacturing costs while maintaining connection stability through the integrated design
Solution Approach 2:
The patent utilizes elastic deformation as a key parameter change mechanism. The center contact material is selected and designed to undergo controlled elastic deformation during assembly, allowing it to securely hold the conducting wire through its recovery force. This parameter-based approach eliminates the need for additional fastening components and reduces manufacturing complexity

AI summary
A connector for connecting to a cable having a conducting wire includes an outer shield adapted to receive the cable. A holder is mounted within the shield and receives a center contact of the connector. The center contact receives and electrically contacts the conducting wire, with at least a portion of the center contact being elastically deformed by the conducting wire as it is inserted into the center contact.
