Solution Overview
Problem
Existing millimeter wave connectors are fragile and prone to damage from frequent connections and disconnections, which can affect their electrical performance.
Innovation Solution
A dual adapter system comprising an internal and external adapter connected by a tensioning means and a spring element, which redirects torsional and rotational forces to maintain consistent contact pressure and protect against damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single adapter design is used, then the structure is simple, but the connector is fragile and prone to damage from frequent connections and disconnections
Solution Approach 1:
The adapter is divided into two separate components: a internal adapter that remains fixed in the device and an external adapter that can be removed and replaced. This segmentation allows the fragile external connector to be exchanged when worn, while the robust internal adapter remains in place, resolving the contradiction between structural simplicity and connector durability.
2Device complexity
If the external adapter is directly connected to the internal adapter, then the connection is simple, but tilting and torsional moments damage the fragile external connector
Solution Approach 1:
A spring element is introduced as an intermediary component between the external and internal adapters. This spring element absorbs tilting and torsional moments, protecting the fragile external connector from damage while maintaining the simplicity of the connection structure.
3Strength
If a rigid connection is used, then the mechanical strength is high, but the contact force varies with mechanical tolerances and thermal expansion
Solution Approach 1:
The connection transitions from a rigid fixed-state to a dynamic elastic state through the spring element. This allows the contact force to self-adjust and remain consistent despite variations in mechanical tolerances and thermal expansion, resolving the contradiction between mechanical strength and contact force consistency.
4Reliability
If the external adapter is integrated into the device, then the connection is stable, but replacement of worn connectors requires device disassembly
Solution Approach 1:
The adapter system is segmented into replaceable external and fixed internal components. The external adapter can be easily removed and replaced without device disassembly, while the internal adapter remains integrated for stability, resolving the contradiction between connection stability and ease of repair.

AI summary
A coaxial RF connection system includes an external adapter with an external body and therein an external inner conductor. The coaxial RF connection system further includes an internal adapter with an internal body. The external body has an external body contact surface, and the internal body has an internal body contact surface. The coaxial RF connection system further includes a tensioning means, and a spring element. The tensioning means presses by means of the spring element the external body against the internal body in a direction of the center axis, such that the external body contact surface is in contact with the internal body contact surface, and the external body comprises an external centering device which is aligned along the center axis with an internal centering device of the internal body.
