Shielding Connector Back Shell Stabilization via Conductive Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connectors face instability in the posture of the back shell when its shape or size is changed to accommodate an integrated circuit, leading to structural instability and increased costs due to the need for altering the back shell alone.
Innovation Solution
A connector design featuring a front shell with first contact and fixed portions, and a back shell with second contact and opening portions, where the second contact portion is in contact with the first contact portion, allowing for stabilization using a conductive fixing agent, enabling the back shell to be fixed to the front shell without altering the connector's structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the back shell shape or size is changed to accommodate an integrated circuit, then the adaptability is improved, but the structural stability deteriorates
Solution Approach 1:
The connector is divided into front shell and back shell as separate modular components. The back shell can be independently changed in shape or size to accommodate different integrated circuits without affecting the front shell structure, while maintaining stable positioning through the contact portion interface.
Solution Approach 2:
The contact portion structure serves multiple functions: it provides electrical connection between front and back shells, acts as a positioning mechanism to stabilize the back shell posture, and enables modular replacement of the back shell for different IC configurations.
2Ease of manufacture
If only the back shell is changed to meet mounting requirements, then the manufacturing cost is reduced, but the posture stability worsens
Solution Approach 1:
The contact portion is pre-designed with specific geometric features that automatically provide positioning and stabilization functions when the back shell is assembled to the front shell, eliminating the need for additional stabilization components.
3Stability of the object's composition
If the back shell structure is modified to stabilize posture, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The positioning and stabilization functions are merged into the contact portion structure itself, which also serves as the electrical connection interface. This integration eliminates the need for separate positioning mechanisms or additional components.
Solution Approach 2:
The contact portion simultaneously performs electrical connection, mechanical coupling, and positioning/stabilization functions, reducing overall device complexity while ensuring back shell posture stability.

AI summary
A connector has a front shell and a back shell. The front shell is provided with a first contact portion and a fixed portion. The first contact portion surrounds a periphery of the fixed portion in a plane orthogonal to a predetermined direction. The back shell is provided with an opening portion and a second contact portion. The second contact portion surrounds a periphery of the opening portion in a plane orthogonal to the predetermined direction. The second contact portion is in contact with the first contact portion in the predetermined direction so that the fixed portion is visible within the opening portion in the predetermined direction and that the back shell is positioned with respect to the front shell. The fixed portion and the second contact portion are fixable to each other using a conductive fixing agent through the opening portion.
