Half-Shell Clamping Sleeve for Shielded Circular Connector Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional round connectors face challenges in achieving secure electrical shielding between the connector and cable, particularly in high-frequency applications, due to difficulties in aligning and securing the half-shells and clamping sleeve for effective shielding.
Innovation Solution
The introduction of a half-shell clamping sleeve with a groove on one front and a clamping sleeve on the opposite front, which aligns with the connection element of the round connector, allows for mechanical and electrical connection of the cable, replacing the need for two separate half-shells and a clamping sleeve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate half-shells and a clamping sleeve are used for shielding, then electrical shielding is achieved, but assembly complexity increases and alignment difficulty arises
Solution Approach 1:
The patent combines two separate half-shells and a clamping sleeve into a single integrated half-shell clamping sleeve component. This unified structure performs both shielding and clamping functions simultaneously, eliminating the need for separate alignment and assembly of multiple parts, thus reducing assembly complexity while maintaining electrical shielding effectiveness.
Solution Approach 2:
The half-shell clamping sleeve serves multiple functions: it provides electrical shielding for the cable area, mechanically clamps the cable through the integrated clamping sleeve portion, and ensures proper alignment via the groove feature. This multi-functional design replaces what previously required three separate components, simplifying the overall assembly process.
2Device complexity
If a rigid metal cylinder shielding element is used, then shielding structure is simple, but contact reliability with cable braid deteriorates due to movement
Solution Approach 1:
The patent introduces a groove on the first end face of the half-shell clamping sleeve that enables dynamic adjustment and self-alignment during assembly. This groove allows the component to adapt to slight movements and misalignments, maintaining reliable contact with the cable braid while preserving the simplicity of the shielding structure.
3Ease of manufacture
If conventional alignment methods are used for half-shells and clamping sleeve, then assembly is possible, but time consumption and precision requirements increase
Solution Approach 1:
The groove is pre-formed on the half-shell clamping sleeve during manufacturing, establishing the alignment feature in advance. This preliminary action eliminates the need for complex alignment procedures during assembly, as the groove automatically guides proper positioning of the component relative to the connection element, significantly reducing assembly time and precision requirements.
