Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connectors suffer from position-dependent interference that negatively affects high-frequency transmission properties due to geometric variations and resonant structures formed by the outer conductor geometry, leading to capacitive loading and phase modulation issues.
Innovation Solution
Incorporation of a limiting element, such as a limiting ring, to restrict the maximum lateral deflection of the adapter relative to the connector parts, maintaining a stable minimum distance and preventing harmful resonant structures, thereby enhancing signal transmission by reducing disruptive decoupling of the transmission signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the adapter is allowed to deflect laterally to compensate for position inaccuracies, then the connector can accommodate radial and axial offsets, but harmful resonant structures are formed and capacitive loading occurs which degrades high-frequency transmission properties
Solution Approach 1:
The patent changes the physical state and geometric parameters of the outer conductor by forming a groove that removes material, thereby altering the resonant characteristics and capacitive coupling of the structure to eliminate harmful high-frequency effects while preserving lateral deflection capability
Solution Approach 2:
The groove in the outer conductor effectively removes a portion of the conductive material, extracting the problematic resonant structure and capacitive coupling path while retaining the essential connector functionality and position compensation capability
2Adaptability or versatility
If multiple contact points are connected simultaneously to compensate for position errors, then radial and axial offsets are accommodated, but position-dependent interference occurs which negatively affects transmission properties
Solution Approach 1:
The groove modification changes the electrical and mechanical parameters of the outer conductor, altering how multiple contact points interact and reducing the position-dependent interference while maintaining the ability to accommodate offsets
3Ease of operation
If the outer conductor geometry allows freedom of movement for position compensation, then lateral deflection is possible, but resonant structures are formed at high frequencies causing phase modulation and interference
Solution Approach 1:
The groove removes the specific geometric features of the outer conductor that create resonant structures, extracting the harmful high-frequency effects while preserving the lateral mobility needed for position compensation
Solution Approach 2:
By changing the geometric parameters of the outer conductor through groove formation, the resonant frequency and capacitive coupling are modified to eliminate harmful effects while maintaining operational flexibility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively minimizes interference and maintains stable signal transmission, especially at high frequencies, by limiting the lateral deflection and preventing capacitive loading, thus ensuring reliable operation under vibration and shock loads.
Implementation Method 1
The adapter also has an inner conductor and an outer conductor, which are held against each other by an insulator. The adapter also has an inner conductor and an outer conductor, which are held against each other by an insulator. The outer conductor of the adapter has elastic spring tongues at both ends with radially projecting contact beads
Implementation Method 2
The disruptive decoupling of the transmission signal on the outer conductor of the connecting element is reduced to such an extent that it no longer has a negative influence. The resonance frequency is detuned by the fact that when the adapter is deflected (tilted) to the side, the outer conductor of the adapter (at a distance from the spring tongues) comes close to an edge of the electrically conductive housing

AI summary
The invention relates to a coaxial connector (1) having a first and a second connector part (2, 3) and an adapter (4) arranged between said connector parts. When installed, the adapter (4) is arranged in an opening (6) in an external conductor (8) of the first connector part (2, 3) such that it can fold out laterally. A limiting element (9) made from an insulating material is arranged in the region of the entrance to the opening (6) so that it limits the lateral movement of the adapter.
