Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF connectors struggle with accurately connecting substrates when assembling tolerance is present, leading to potential damage and increased repair costs due to difficulty in identifying connection points and applying excessive force.
Innovation Solution
A connecting apparatus with elastically supported terminal parts that absorb assembling tolerance by slipping and hook-engaging with a fixed terminal part, allowing easy alignment and stable connection between substrates, and includes a cavity filter with impedance matching features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RF connectors are used to connect substrates, then electrical signal transmission is enabled, but assembling tolerance causes misalignment and connection failure
Solution Approach 1:
The connector pin is designed with a cut-out groove that changes its structural parameter, allowing it to be flexible in one direction while maintaining rigidity in another. This enables the pin to absorb assembling tolerance through controlled deformation rather than requiring precise alignment
Solution Approach 2:
The cut-out groove structure acts as a pre-designed cushioning mechanism that anticipates and absorbs assembling tolerance before connection occurs. The groove allows the pin to deform elastically during assembly, preventing connection failure due to misalignment
2Manufacturing precision
If cut-out groove is provided outside the connection groove, then tolerance absorption is improved, but coupling stability is insufficient
Solution Approach 1:
The connector pin combines rigid material properties with a localized flexible structure (cut-out groove). This composite approach allows the overall structure to remain stable while the specific groove region provides tolerance absorption capability
Solution Approach 2:
The cut-out groove is strategically positioned at the tip of the connector pin where flexibility is needed, while the rest of the pin maintains its rigid structure for stable coupling. This local modification provides tolerance absorption without compromising overall coupling stability
3Productivity
If excessive force is applied during assembly, then connection is forced, but connector contact point is damaged
Solution Approach 1:
The cut-out groove acts as an intermediary mechanism that mediates between the assembly force and the connector structure. It allows controlled deformation under excessive force, preventing direct transmission of damaging forces to the contact point while still enabling connection
4Device complexity
If rotation is not implemented in RF connectors, then structure is simple, but stable connection cannot be achieved when substrates are coupled
Solution Approach 1:
The connector pin transitions from a static rigid structure to a dynamic structure with the cut-out groove that allows controlled movement and deformation. This dynamic capability enables the pin to adapt to misalignment and achieve stable connection without requiring complex rotation mechanisms

AI summary
The present invention relates to a connecting apparatus including a fixed terminal part having a hollow portion and fixed in a predetermined space between a first substrate, on which electrical components are mounted, and a second substrate disposed in parallel with the first substrate, one terminal part fixed to one end of the fixed terminal part and configured to be elastically supported on the first substrate, one terminal part being configured to slip and come into contact with an inner surface of the first substrate, and the other terminal part fixed to the other end of the fixed terminal part and configured to be elastically supported on the second substrate, the other terminal part being configured to slip and come into contact with an inner surface of the second substrate, in which one terminal part and the other terminal part are elastically supported by an elastic member installed in the hollow portion of the fixed terminal part and configured to be extended or contracted, thereby providing an advantage of easily absorbing assembling tolerance existing between two substrates and provides a very simple assembling process.
