1Reliability
If a multipartite connector construction with adapter piece is used, then radiofrequency properties are maintained, but device complexity increases
Solution Approach 1:
The connector is divided into three separate parts: a first connector part, a second connector part, and an adapter piece. Each part has specific functional elements (conductors, operative-connection means) that work together to maintain radiofrequency properties while allowing modular assembly and compensation for positional inaccuracies.
Solution Approach 2:
The adapter piece serves as an intermediary element between the first and second connector parts. It provides the necessary connection interface and compensation mechanism for lateral and axial offsets, enabling the two connector parts to be operatively connected even when positional accuracy is not perfect.
2Stability of the object's composition
If mechanical operative-connection means are used to connect connector parts, then connection stability is improved, but movement play is reduced
Solution Approach 1:
The mechanical operative-connection means are designed to provide a dynamic connection that is stable under normal conditions but allows for controlled movement and offset compensation. The connection can accommodate lateral and axial displacements while maintaining electrical contact, adapting to positional variations without compromising stability.
Solution Approach 2:
The connector design allows for parameter changes in position (lateral and axial offsets) while maintaining the functional connection. The operative-connection means are arranged to permit these parameter changes within a certain range, enabling the connector to adapt to manufacturing tolerances and assembly variations.
3Adaptability or versatility
If connector parts are arranged to compensate for lateral offset, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adapter piece acts as a mediator that absorbs and compensates for lateral offsets between the first and second connector parts. By placing the adaptive functionality in the adapter rather than in each connector part, the overall system achieves offset compensation with minimal increase in complexity.
Solution Approach 2:
The adapter piece serves multiple functions: it provides the electrical connection interface, compensates for lateral and axial offsets, and enables the operative connection between the two connector parts. This multi-functionality reduces the need for additional specialized components.
4Adaptability or versatility
If sleeve-shaped conductor with telescopic configuration is used, then axial displacement compensation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The sleeve-shaped inner conductor is designed with a telescopic configuration that allows it to move axially relative to the adapter piece. This dynamic capability enables the connector to compensate for axial displacements and variations in circuit board distance, adapting to manufacturing tolerances rather than requiring high precision.
Solution Approach 2:
The sleeve-shaped inner conductor is nested within the adapter piece structure, with the ball-like element dipping into the sleeve. This nested arrangement allows for controlled axial movement and telescopic configuration while maintaining the overall structural integrity and electrical connection.

AI summary
The invention relates to a coaxial connector (1), comprising a first and a second connector part (2, 3) and an adapter (4) arranged therebetween. The first and the second connector part (2, 3) include a first inner conductor (5) and a first outer conductor (8), including a first internal cylindrical contact surface (24) and a second internal cylindrical contact surface (25), respectively. In a socket area (17) of the first inner conductor (5), a first mechanical operative-connection means interacts with a second mechanical operative-connection means (11) in the installed state in order to establish a mechanical connection (13) that is effective in the axial direction (z). The first inner conductor (5) protrudes beyond the level of the mechanical operative-connection means (10, 11) so the internal cylindrical contact surface (24) is able to compensate a large axial offset (dz) of the connector parts (2, 3) relative to the adapter (4).
