Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency measuring devices face damage due to axial and radial forces applied to the inner conductor of coaxial jacks, which are transmitted to sensitive circuit carriers during plug connections, leading to potential damage.
Innovation Solution
Incorporating a resilient bellows within the inner conductor of the coaxial connecting element to absorb and dissipate these forces, preventing them from reaching the sensitive connection point with the circuit carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the inner conductor is made rigid for stable connection, then connection stability is improved, but the circuit carrier becomes vulnerable to damage from axial and radial forces
Solution Approach 1:
The patent applies a bellows structure (flexible element) within the inner conductor that can deform axially and radially to absorb forces generated during plug connection, preventing these forces from reaching the circuit carrier while maintaining connection stability
Solution Approach 2:
The patent changes the mechanical parameter of the inner conductor by introducing a flexible bellows section with specific deformation characteristics, allowing it to adaptively absorb forces while maintaining electrical connection integrity
2Object-affected harmful factors
If a flexible bellows is inserted in the inner conductor to absorb forces, then protection of circuit carrier is improved, but device complexity increases
Solution Approach 1:
The bellows is nested within the existing inner conductor structure, integrating the force-absorbing function into the conductor itself rather than adding external components, thus minimizing overall device complexity
Solution Approach 2:
The bellows acts as an intermediary element between the outer conductor and the circuit carrier, absorbing forces before they can reach the sensitive circuit carrier while maintaining the electrical connection pathway
3Force
If the bellows deforms to absorb forces, then force absorption is improved, but reflection increases
Solution Approach 1:
The patent carefully controls the geometric parameters of the bellows (dimensions, corrugation pattern, material properties) to optimize the balance between force absorption capability and electromagnetic performance, minimizing signal reflection while maintaining mechanical flexibility

AI summary
The invention relates to a coaxial connecting part which is used to connect a coaxial plug socket to a circuit carrier in an internal conductor. An elastically flexible bellows made of a conductive material is incorporated therein in order to keep axial and radial forces, occurring at the beginning of the socket, away from the substrate.
