Shield Connector Assembly for Impedance-Stable Bent Inner Conductors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield connectors face impedance mismatch issues when the inner conductor terminal is formed by bending a flat metal plate in the plate thickness direction, leading to potential deformation and reduced communication performance.
Innovation Solution
A shield connector design featuring an inner conductor with a first and second connecting portion extending from a bent portion in different directions, integrated with a dielectric and an outer conductor, where the dielectric includes terminal accommodating portions to securely hold the connecting portions without pressing the inner conductor in the plate thickness direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the inner conductor terminal is formed by bending a flat plate member in the plate thickness direction, then the inner conductor can be shaped to connect multiple portions, but the pressing force applied to the bent portion causes deformation of the inner conductor terminal
Solution Approach 1:
The patent changes the pressing direction from the plate thickness direction to a direction intersecting the longitudinal direction of the first connecting portion. This dimensional change in the pressing direction allows the inner conductor to be fixed without causing deformation at the bent portion, while still achieving secure mounting in the dielectric.
2Reliability
If a narrow portion is formed by cutting side edge parts to prevent deformation, then the inner conductor can be pressed without deformation, but an impedance mismatch occurs between the narrow portion region and other regions
Solution Approach 1:
Instead of forming a narrow portion by cutting in the width direction, the patent applies pressing force in a direction intersecting the longitudinal direction of the first connecting portion. This approach prevents deformation without creating a narrow portion, thereby avoiding impedance mismatch while maintaining reliable fixation.
3Ease of manufacture
If the cover member is assembled in the plate thickness direction, then the assembly process is simple, but the inner conductor may be deformed during assembly
Solution Approach 1:
The cover member is assembled in a direction intersecting the longitudinal direction of the first connecting portion rather than in the plate thickness direction. This dimensional change in the assembly direction prevents deformation of the inner conductor during assembly while still achieving secure fixation.

AI summary
A shield connector includes an inner conductor shaped by bending an elongated metal plate material in a plate thickness direction and including a first connecting portion and a second connecting portion extending from a bent portion in directions different from each other, a dielectric to be mounted with the inner conductor, and an outer conductor for surrounding the dielectric. The dielectric includes a first terminal accommodating portion for surrounding and accommodating the first connecting portion over an entire periphery and a second terminal accommodating portion for accommodating the second connecting portion. The first terminal accommodating portion includes a body member integrally molded with the second terminal accommodating portion and a cover member to be assembled with the body member in a direction intersecting a longitudinal direction of the first connecting portion.
