Shielding Shell With Deflection Portions for Guided Connector Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backplane connector assemblies lack effective shielding for signal terminals and guidance during mating, which affects data transmission quality.
Innovation Solution
A shielding shell with inwardly bent deflection portions on its side walls is designed to partially surround signal terminals, providing enhanced shielding and guiding the shell's insertion into the mating connector.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a shielding shell is designed to surround signal terminals, then the shielding effect is improved, but the device complexity increases
Solution Approach 1:
The shielding shell is divided into a body portion and a separate deflection portion. The deflection portion is bent inwardly from the body portion to form a guiding structure. This segmentation allows the shielding shell to provide both shielding and guiding functions while maintaining manufacturing simplicity through a single-piece construction approach.
Solution Approach 2:
The patent combines multiple functions into a single shielding shell component: electromagnetic shielding, insertion guidance, and structural support. The deflection portion integrated into the body portion provides guiding function without requiring separate guiding elements, thereby reducing overall device complexity while improving shielding effectiveness.
2Ease of operation
If deflection portions are added to guide insertion, then the ease of operation is improved, but the manufacturing complexity increases
Solution Approach 1:
The deflection portions are pre-formed as bent structures extending inwardly from the body portion during the manufacturing process. This preliminary formation of the guiding structure eliminates the need for additional assembly steps or separate guiding components, as the guidance function is built into the shielding shell itself during initial fabrication.
Solution Approach 2:
The patent utilizes bending and deformation of metal sheets to create the deflection portions. By changing the geometric parameters of the metal sheet during forming (creating inwardly bent sections), the guiding function is achieved through standard metal forming processes rather than requiring complex machining or assembly operations.

AI summary
A shielding shell used to at least partially surround signal terminals includes a first side wall, a second side wall and a third side wall. The second side wall connects the first side wall and the third side wall. The first side wall and the third side wall are disposed face to face. An end of at least one of the first side wall, the second side wall and the third side wall includes a deflection portion bent inwardly. The deflection portion is used to guide insertion of the shielding shell into a mating connector. As a result, a better shielding effect on the signal terminals can be provided. Besides, it is easy to guide insertion of the shielding shell into the mating connector.
