Plug Connector Anti-Rotation Locking via C-Ring Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug-in connectors lack reliable anti-rotation locking for the insulating part, which affects the assembly and operational stability, particularly since the outer conductor part is not designed to provide anti-rotation locking for the insulating part within the housing.
Innovation Solution
A plug-in connector design featuring a housing that secures both the outer conductor and insulating parts, with an anti-rotation lock in the form of a C-ring that fits through the outer conductor part and into the insulating part, ensuring secure rotation between the housing and insulating part, bypassing the outer conductor for anti-rotation locking, and allowing for reliable mechanical and electrical connection to a cable's outer conductor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the outer conductor part is designed to provide anti-rotation locking for the insulating part, then the assembly complexity is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent introduces an intermediary anti-rotation lock component that mediates between the insulating part and the housing. This lock features a C-shaped body with a protrusion that engages with a corresponding recess in the insulating part, while the C-shape allows it to engage with the housing. This intermediary component resolves the contradiction by providing anti-rotation locking without requiring direct precision engagement between the outer conductor and insulating part.
Solution Approach 2:
The patent segments the anti-rotation locking function into separate components: the anti-rotation lock as a distinct element from both the outer conductor part and the insulating part. This segmentation allows each component to be manufactured independently with standard tolerances, while the assembled locking mechanism achieves the required precision through the配合 of multiple simpler parts.
2Reliability
If a C-ring anti-rotation lock is used that fits through the outer conductor part, then the anti-rotation locking reliability is improved, but the device complexity increases
Solution Approach 1:
The C-shaped anti-rotation lock serves multiple functions: it provides anti-rotation locking for the insulating part, acts as a structural connector between the insulating part and housing, and its C-shape allows it to be fitted through the outer conductor part. This multi-functionality improves reliability without proportionally increasing complexity, as one component achieves multiple objectives.
Solution Approach 2:
The anti-rotation lock is nested within the connector assembly, with the C-shaped body passing through the outer conductor part and the protrusion engaging with the insulating part. This nesting arrangement integrates the locking mechanism into the existing structure rather than adding external components, thereby improving reliability while minimizing increases in overall device complexity.
3Stability of the object's composition
If the anti-rotation lock is connected to the housing and fits through the outer conductor part, then the operational stability is improved, but the ease of manufacture decreases
Solution Approach 1:
The anti-rotation lock is pre-formed as a C-shaped component with the protrusion already integrated. This preliminary preparation allows the lock to be simply fitted through the outer conductor part and engaged with the housing and insulating part in sequence, improving operational stability while maintaining ease of manufacture through a straightforward assembly process.

AI summary
A plug-in connector having an outer conductor electrically and mechanically connected to an outer conductor of a cable and forming an electromagnetic screen for the plug-in connector, and having an insulating part securing at least one inner conductor part in a predetermined position relative to the outer conductor part, and having a housing in which the outer conductor part and the insulating part are arranged. An anti-rotation lock is connected to the housing to be secure in rotation therewith and which fits through the outer conductor part and into the insulating part such that the insulating part and the housing are connected together by the anti-rotation lock to be secure in rotation with one another.
