Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-sided connection connectors face issues such as frame deformation or breakage, conductor damage, and positioning errors due to high-density connecting portions or improper clearance between positioning pins and holes, leading to contact failures and reduced lifetime.
Innovation Solution
A double-sided connection connector design featuring a first frame with protruding contacts and a second guiding frame that allows movement perpendicular to the connecting direction, utilizing a spring mechanism to distribute force and prevent deformation, while maintaining alignment through tapered surfaces and positioning pins, ensuring stable contact and reduced risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the frame is pressed by the elastic member when connection objects are connected, then electrical connection is established, but the frame may be deformed or broken and the conductor may be damaged causing contact failure
Solution Approach 1:
The frame is divided into a first frame that supports the contacts and a second frame that guides the first frame. This segmentation allows the second frame to absorb and distribute the pressing force through guiding surfaces, preventing the first frame from deforming or breaking while maintaining reliable electrical connection.
2Ease of manufacture
If the clearance between positioning pin and positioning hole is large, then assembly is easier, but wobbling is caused between frame and base insulator making positioning difficult
Solution Approach 1:
The positioning mechanism allows for dynamic adjustment during assembly. The second frame guides the first frame with controlled movement along the connecting direction, enabling the system to adapt to clearance variations while maintaining precise positioning through the guiding surfaces that constrain wobbling motion.
3Manufacturing precision
If the clearance between positioning pin and positioning hole is small, then positioning precision is improved, but the conductor is pressed by base insulator to be largely bent reducing connector lifetime
Solution Approach 1:
The positioning function is extracted from the base insulator-conductor assembly and transferred to the second frame's guiding mechanism. This separates the positioning responsibility from the conductor support structure, allowing precise positioning through the guiding surfaces without the base insulator pressing and bending the conductor.
4Productivity
If connecting portions of connection objects are arranged at higher density, then connection capability is improved, but frame deformation and breakage occurs more easily
Solution Approach 1:
The force distribution mechanism introduces a new dimensional aspect by using inclined guiding surfaces that convert vertical pressing force into diagonal force components. This dimensional transformation allows the frame structure to handle higher connection densities by distributing loads through multiple directional vectors rather than simple vertical compression.

AI summary
In a connector to be connected by press contact in a connecting direction, plural contacts are coupled to a first frame having two principal surfaces opposite to each other in the connecting direction. A second frame is coupled to the first frame and guides the first frame in a specific direction perpendicular to the connecting direction. Each of the contacts includes an insulating elastic member and a conductor combined with the elastic member. The conductor includes portions protruding from the principal surfaces, respectively.
