Shielded Connector Asymmetric Projections Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector design with a symmetrical rectangular tube shape makes it difficult to visually confirm the vertical and lateral orientations, leading to potential posture inclination during crimping and improper insertion into a housing.
Innovation Solution
The connector features a multi-functional portion in the form of projections on the outer surface, which are used to confirm orientation, and locking portions that prevent posture inclination during crimping, with the multi-functional portions exposed on the dielectric and crimping portions oriented oppositely to the crimping direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outer conductor is constituted by a pair of divided shells with asymmetric shapes, then the orientation can be distinguished by visual observation, but the front end parts of the divided shells may become inclined during crimping
Solution Approach 1:
The patent applies asymmetry by forming asymmetric shapes on the outer surface of the dielectric (such as protrusions or recesses) that are visible through the outer conductor. This allows the vertical and lateral orientations of the connector to be easily distinguished during insertion, solving the orientation identification problem while maintaining the structural integrity needed for stable crimping.
Solution Approach 2:
The patent implements preliminary anti-action by providing locking portions on the inner surface of the outer conductor that correspond to the asymmetric shapes on the dielectric. These locking portions prevent the divided shells from becoming inclined during crimping by mechanically constraining them in the correct orientation before the crimping force is applied, thus preventing the posture instability issue.
2Device complexity
If the front end part of the connector has a vertically and laterally symmetrical rectangular tube shape, then the structure is simple, but it is difficult to confirm the vertical and lateral orientations by visual observation
Solution Approach 1:
The patent introduces asymmetric shapes (such as protrusions or recesses) on the outer surface of the dielectric that correspond to the asymmetric division of the outer conductor. These asymmetric features are visible through the outer conductor and provide clear visual indicators for correct orientation, enabling easy confirmation of vertical and lateral orientations while maintaining relatively simple connector structure.
3Stability of the object's composition
If the locking portions are disposed to lock the multi-functional portion, then posture inclination during crimping is prevented, but the multi-functional portion must be exposed on the outer surface
Solution Approach 1:
The patent applies multi-functionality by designing the asymmetric shapes on the dielectric to serve dual purposes: they act as visual indicators for orientation identification and simultaneously serve as locking engagement features that prevent posture inclination during crimping. This eliminates the need for separate locking structures, preventing posture instability while avoiding additional structural complexity.
