Sealing Ring Positioning Component for Connector Shield Shell Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The gap between the splicing edges of the two half shells in a connector's shielding shell reduces the electromagnetic shielding effect due to incomplete closure, which is a result of the need for injection molding slopes.
Innovation Solution
A sealing ring positioning component with a peripheral wall and pushing protrusions is fitted on the outer housing to push the half shells of the shielding shell into continuous contact, eliminating the gap and enhancing electromagnetic shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the outer housing is designed with a certain slope to facilitate injection molding and release from mold, then the ease of manufacture is improved, but a gap is created between the splicing edges of the two half shells of the shielding shell, worsening the electromagnetic shielding effect
Solution Approach 1:
A sealing ring positioning component is introduced as an intermediary element between the outer housing and the shielding shell. This component includes a pushing protrusion that actively pushes the two half shells toward each other, forcing the splicing edges into continuous contact. The sealing ring positioned by this component fills the gap created by the sloped outer housing design, thereby restoring electromagnetic shielding effectiveness while preserving the ease of injection molding
2Ease of manufacture
If the two half shells of the shielding shell are allowed to have a gap for ease of assembly and manufacturing, then the ease of manufacture is improved, but the reliability of electromagnetic shielding is worsened
Solution Approach 1:
The sealing ring positioning component is designed to automatically push the half shells into proper alignment and continuous contact during the assembly process. The pushing protrusion structure enables the component to self-adjust and self-position the shielding shell halves, ensuring reliable electromagnetic shielding without requiring complex external alignment tools or procedures, thus maintaining ease of assembly while improving reliability

AI summary
A sealing ring positioning component adapted to be fitted on an outer housing of a connector to position a sealing ring on the outer housing comprises a peripheral wall and a pushing protrusion formed on an inner peripheral surface of the peripheral wall. The pushing protrusion is adapted to be pushed on the outer sides of two half shells of a shielding shell of the connector such that splicing edges of the two half shells of the shielding shell are in contact with each other.
