Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
L-shaped coaxial terminals face reduced shielding effectiveness due to gaps in the external terminal's curved section, which can lead to signal leakage and noise contamination, as the curved shape is difficult to maintain as a continuous tubular form.
Innovation Solution
The connector incorporates shielding members made from electrically conductive material that cover and electrically connect the external terminal's curved sections, forming a continuous path from the conductor mounting to the terminal connecting portion, and a coupling member that connects these shielding members to enhance shielding effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the external terminal is formed by bending a metal sheet to create an L-shaped curved section, then the connector achieves L-shaped configuration for orthogonal mounting, but gaps are formed in the curved section reducing shielding effectiveness
Solution Approach 1:
A shielding member made of electrically conductive material is introduced as an intermediary element to bridge the gap in the external terminal's curved section. This shielding member is disposed within the curved section and electrically connects the front end and rear end of the external terminal, thereby maintaining continuous shielding without compromising the L-shaped configuration.
Solution Approach 2:
The external terminal is divided into front end and rear end portions that are bent at an angle to form the L-shape, while the shielding member is separately formed and then integrated into the curved section. This segmentation allows the external terminal to achieve the desired L-shaped configuration while the separate shielding member compensates for the shielding gap created by the bending process.
2Reliability
If the external terminal is made continuous and tubular like rectilinear terminals, then shielding effectiveness is maximized, but L-shaped configuration cannot be achieved
Solution Approach 1:
The shielding member acts as a mediator that restores the continuous electrical path for shielding in the curved section of the L-shaped external terminal. By placing this conductive shielding member inside the curved section and electrically connecting both ends of the external terminal, the invention achieves both the L-shaped configuration and effective shielding.
3Shape
If the metal sheet piece is bent to form the curved L-shape, then the connector achieves the required orthogonal structure, but the internal terminal's outer periphery cannot be completely surrounded
Solution Approach 1:
The shielding member extends in the axial direction of the external terminal, adding a dimensional element that fills the gap created by the L-shaped bending. This axial extension ensures that the inner conductor is completely surrounded by the shielding structure, restoring full shielding coverage while maintaining the L-shaped configuration.

Function Achieved in This Case
This configuration significantly enhances shielding effectiveness by minimizing signal leakage and noise contamination, even in L-shaped coaxial terminals, by creating a continuous electrical path and stable grounding.
