Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector structure is designed to accommodate positional misplacement, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The connector is divided into separate functional components: an inner conductor portion for signal transmission and an outer conductor portion for shielding and reference potential. This segmentation allows each part to be optimized independently for its specific function while accommodating positional misplacement through the flexible contact design of the inner conductor.
Solution Approach 2:
The inner conductor contact portion is designed with dynamic characteristics, allowing it to move or deform elastically to accommodate positional misplacement between the connector and connection target. This dynamic design enables the connector to adapt to varying positions without requiring complex mechanical adjustment mechanisms.
2Reliability
If the shield member is added to improve high-speed transmission performance, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The shield member is merged with the outer conductor portion of the connection target, forming an integrated shielding structure. This combination provides effective electromagnetic shielding for high-speed signal transmission while avoiding the need for separate, complex shielding components. The outer conductor serves dual purposes as both a structural element and a shield.
Solution Approach 2:
The outer conductor portion is designed to serve multiple functions: providing a reference potential for signal transmission, offering electromagnetic shielding, and enabling mechanical connection. This multi-functionality reduces the need for additional components and simplifies the overall connector structure while maintaining high-speed transmission performance.
3Manufacturing precision
If the inner conductor contact portion and outer conductor contact portion are aligned in the Z-direction, then the manufacturing precision is improved, but the adaptability decreases
Solution Approach 1:
The inner conductor contact portion is designed with dynamic characteristics, allowing it to move or deform elastically to accommodate positional misplacement between the connector and connection target. This dynamic design enables the connector to adapt to varying positions without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The contact portions are designed with adjustable contact pressure and deformation characteristics. By changing the mechanical parameters such as spring constant and contact force, the connector can accommodate a range of positional misplacements while maintaining reliable electrical contact. The inner conductor can deform within elastic limits to compensate for alignment variations.

AI summary
A connector having excellent high speed transmission performance while also having a positional misplacement accommodation function is provided.A connector includes a signal terminal including a terminal contact portion capable of making electrically contiguous contact with a first contact portion of a connection target for connection from a Z direction one side, a housing that retains the signal terminal, and a shell that surrounds at least part of the signal terminal. The shell includes a shield contact portion that makes electrically contiguous contact with a second contact portion of the connection target. The shell is able to displace in the Z direction.
