Sealing Ring Positioning Structure for Gap-Free Connector Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connectors suffer from reduced electromagnetic shielding due to gaps between the splicing edges of the shielding shell's half shells, caused by the need for injection molding slopes, which compromises the integrity of the sealing and electrical contact.
Innovation Solution
A sealing ring positioning component with protruding ribs or a single rib extending along the circumferential direction is used to push the half shells of the shielding shell into contact, ensuring a gap-free splicing edge and enhancing electromagnetic shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the outer housing is designed with injection molding slopes to facilitate manufacturing, then the ease of manufacture is improved, but gaps are formed between the splicing edges of the two half shells of the shielding shell, reducing the electromagnetic shielding effect
Solution Approach 1:
A positioning component with a pushing protrusion is introduced as an intermediary element between the outer housing and the shielding shell. This positioning component fills the gap created by the injection molding slope and pushes the two half shells of the shielding shell together, ensuring their splicing edges are in contact. This resolves the contradiction by maintaining electromagnetic shielding effectiveness while preserving the ease of manufacture through injection molding slopes.
2Ease of manufacture
If the two half shells of the shielding shell are kept separate to accommodate the injection molding slope, then the ease of manufacture is improved, but the splicing edges do not contact each other, creating gaps that reduce electromagnetic shielding
Solution Approach 1:
The positioning component acts as a mediator that bridges the gap between the two half shells. The pushing protrusion of the positioning component applies force to push the splicing edges of the two half shells into contact, ensuring precise alignment and contact while allowing the outer housing to maintain its injection molding slope for ease of manufacture.
Solution Approach 2:
The positioning component is pre-installed on the outer housing before the shielding shell is assembled. The pushing protrusion is already in position to apply the necessary force to ensure the splicing edges of the half shells contact each other, eliminating gaps before the electromagnetic shielding function is activated.

AI summary
The present invention discloses a sealing ring positioning component and a connector. The sealing ring positioning component is adapted to be fitted on an outer housing (1) of a connector to positioning a sealing ring (4) on the outer housing (1). The sealing ring positioning component (5) comprises of: a peripheral wall (51); and a pushing protrusion (50) formed on an inner peripheral surface of the peripheral wall (51). The pushing protrusion (50) is adapted to be pushed on the outer sides of two half shells (31a) of a shielding shell (3) of the connector, so that the splicing edges (31b) of the two half shells (3 1a) of the shielding shell (3) are in contact with each other. In the present invention, the sealing ring positioning component can push the two half shells of the shielding shell towards the closed direction, so that the splicing edges of the two half shells of the shielding shell come into contact with each other without gap, improving the electromagnetic shielding effect of the connector.
