Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical right angle RF connector assemblies are complex and costly to design, manufacture, and assemble, with difficulties in maintaining impedance and shielding due to multiple components and manual assembly processes, which hinder automated manufacturing and effective signal path shielding.
Innovation Solution
A right angle connector assembly featuring a dielectric body with a rotatable door and staggered closing tabs in the front shield, allowing for automated assembly and improved shielding by confining the female center contact within the dielectric, reducing the number of components, and enabling mass production techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual pieces are used in typical RF connectors, then shielding and structural integrity are improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines multiple separate components into an integrated one-piece dielectric housing that fully surrounds the center contact. This single molded piece includes integrated shielding structures and positioning features, eliminating the need for multiple separate shields and housing pieces, thereby reducing assembly steps while maintaining shielding effectiveness
Solution Approach 2:
The one-piece dielectric housing performs multiple functions simultaneously: it provides structural support, maintains impedance, provides shielding, positions the center contact, and enables automated assembly through integrated features. This multi-functional design reduces the overall component count while maintaining all necessary functions
2Adaptability or versatility
If manual bending and assembly processes are used, then customization and flexibility are improved, but productivity and assembly time increase
Solution Approach 1:
The center contact is pre-formed with the correct geometry and impedance characteristics before assembly. The dielectric housing is pre-molded with integrated positioning features and shielding structures. These preliminary actions eliminate the need for manual bending and adjustment during assembly, enabling automated high-speed assembly while maintaining precision
Solution Approach 2:
The integrated design features self-aligning and self-positioning characteristics that allow components to automatically assume correct positions during automated assembly. The one-piece housing self-contained structure eliminates the need for manual intervention, enabling the assembly process to serve itself through automated placement and securing mechanisms
3Ease of manufacture
If the dielectric insert does not fully surround the center contact, then manufacturing simplicity is improved, but shielding and signal quality deteriorate
Solution Approach 1:
The patent merges the dielectric housing and shielding structures into a single integrated one-piece component. This unified structure completely surrounds the center contact, providing full 360-degree shielding and impedance control, while eliminating the complexity of assembling multiple separate shielding pieces, thus achieving both complete shielding and manufacturing simplicity

AI summary
A connector assembly includes a dielectric having a right angle body including a first segment and a second segment and defining a right angle chamber extending through the first and second segments. At least one door at a right angle corner of the body provides access to the right angle chamber through a rear opening in an open state, and restricts access to the rear opening in a closed state. A female center contact in the right angle chamber in the first segment has a terminating end configured to electrically connect to a cable conductor of a cable received in the right angle chamber in the second segment. A front shield receives the dielectric and forces the door to move from the open state to the closed state upon loading the dielectric into the front shield. A rear shield couples to the front shield.
