Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a pair of spring plates is used to clamp the internal conductor, then the connection structure is simple, but the clamping force is insufficient and the connection is unstable
Solution Approach 1:
The connection structure is segmented into multiple spring plate groups (first spring plate group and second spring plate group) positioned at different locations around the central conductor. Each spring plate group independently provides clamping force, and the segmented arrangement allows the structure to adapt to conductors of different diameters while maintaining sufficient overall clamping force without excessive complexity
Solution Approach 2:
Multiple spring plate groups are merged into a single integrated connection structure that works together to provide enhanced clamping force. The spring plates in different groups cooperate to secure the internal conductor, combining their individual clamping actions into a unified force system that prevents conductor displacement
2Reliability
If the connection structure is made more robust to increase clamping force, then the connection becomes more stable, but the resiliency limit decreases due to over-expansion
Solution Approach 1:
The spring plates are designed as elastic components that dynamically adjust their clamping force based on the diameter of the inserted internal conductor. When a conductor is inserted, the spring plates expand to engage it; when removed, they return to their original state. This dynamic behavior allows the structure to provide strong clamping force when needed while maintaining resiliency and avoiding permanent deformation
Solution Approach 2:
The physical state of the spring plates changes between a relaxed state (when no conductor is present) and an engaged state (when clamping the conductor). This parameter change allows the connection structure to adapt its strength characteristics - providing high clamping force during engagement while maintaining the ability to recover and avoid fatigue through elastic deformation within safe limits
3Force
If the spring plates are made stronger to prevent conductor pull-off, then the clamping force increases, but the contact area decreases leading to poor engagement
Solution Approach 1:
The total clamping force is segmented and distributed across multiple spring plate groups positioned at different locations around the central conductor. Each spring plate group contacts the conductor at a different point, creating multiple contact areas that collectively provide both sufficient clamping force and adequate surface contact for stable electrical engagement
Solution Approach 2:
The connection structure transitions from a single-point or single-line contact to a multi-dimensional contact arrangement. Spring plates are positioned at different angular locations and depths, creating contact points distributed in three-dimensional space around the conductor, thereby increasing the total contact area while maintaining effective clamping force

AI summary
A central conductor of coaxial cable connector includes a barrel, at least one first spring plate group, and at least one second spring plate group. The barrel has two ends forming connection bores, opposite side surfaces respectively forming a first slit and a second slit, and top and bottom walls respectively forming a wall opening and a bottom wall opening. The first spring plate group and the second spring plate group are arranged opposite in direction to each other and each includes spring plates that are arranged to engage each other from upper and lower sides. Each of the spring plates has an end connected to the top or bottom wall of the barrel and an opposite end extending inward of the top wall opening or the bottom wall opening. As such, clamping force is enhanced, contact area is increased, and resiliency limit is improved, so as to provide excellent engagement between conductors.
