HF Angle Plug Connector Inspection Opening Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HF right-angle connectors face challenges in assembly and electrical properties, particularly in achieving effective shielding attenuation and ensuring correct assembly of coaxial cables.
Innovation Solution
The HF right-angle connector features an inspection opening on the outer conductor part that can be closed with a cover part, a rotatable coding housing with mechanical coding, and an elastically deformable latching tongue for precise positioning, along with a locking element and rocker extension for secure connection, all made from a single stamped and bent part for cost-effectiveness and improved electrical shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inspection opening is provided in the outer conductor part to allow visual inspection of the fastening element, then assembly correctness can be verified, but the electrical shielding and attenuation properties deteriorate
Solution Approach 1:
The cover part is designed as a separate component that can be removed or opened to provide inspection access, rather than integrating the inspection function directly into the outer conductor part. This extraction allows the outer conductor to maintain its continuous shielding structure while still enabling visual verification of the fastening element through the removable cover.
Solution Approach 2:
The cover part acts as an intermediary element that mediates between the need for inspection and the need for shielding. When closed, it maintains the shielding integrity; when opened, it provides inspection access without requiring a permanent opening in the outer conductor structure.
2Manufacturing precision
If multiple separate components are used for the outer conductor part, cover part, and coding housing, then each component can be optimized independently, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The outer conductor part, cover part, and coding housing are merged into a single integrated component formed by stamping and bending operations. This consolidation eliminates the need for separate manufacturing processes and assembly steps for these components, reducing overall manufacturing cost and assembly complexity while maintaining the functional advantages of each sub-component.
Solution Approach 2:
The integrated component serves multiple functions simultaneously: the outer conductor provides electrical shielding and structural support, the cover provides inspection access and shielding closure, and the coding housing provides mechanical coding and positioning. This multi-functionality in a single component optimizes manufacturing efficiency.
