Connector Outer Conductor Layout for Accurate PCB Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face manufacturing difficulties in achieving accurate assembly accuracy to restrict position shifts of mounting portions with respect to a circuit board, as the leg portions and mounting portions are provided on separate outer conductors.
Innovation Solution
A connector design with an insulating housing, an electrically conductive outer conductor, and an insulating dielectric, where the positioning and mounting portions are integrated on a common first outer conductor, allowing for precise restriction of position shifts by projecting around a through hole in the bottom surface, simplifying the outer conductor configuration and enhancing assembly accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the leg portions and mounting portions are provided on separate first and second outer conductors, then the connector can be assembled with modular components, but the assembly accuracy needed to restrict position shifts of mounting portions with respect to the circuit board deteriorates and manufacturing difficulty increases
Solution Approach 1:
The patent combines the mounting portions and positioning portions onto a single first outer conductor, eliminating the need for separate second outer conductor with leg portions. This merging resolves the contradiction by achieving both modular assembly (the first outer conductor remains a separate component) and high assembly accuracy (mounting and positioning features are integrated on the same component, eliminating cumulative tolerance errors from multiple assemblies).
2Device complexity
If the mounting portions are provided on a separate second outer conductor, then the outer conductor structure can be divided into functional sections, but the position shift restriction accuracy with respect to the circuit board deteriorates
Solution Approach 1:
The patent merges the mounting portions (for electrical connection) and positioning portions (for mechanical alignment) onto the same first outer conductor. This integration ensures that when the first outer conductor is assembled to the circuit board, both the electrical mounting and mechanical positioning occur simultaneously with a single assembly operation, achieving high position shift restriction accuracy without requiring separate functional sections.
3Adaptability or versatility
If separate first and second outer conductors are used with leg portions for positioning, then the connector can distribute functions across components, but the manufacturing difficulty increases due to enhanced assembly accuracy requirements
Solution Approach 1:
The patent consolidates both mounting and positioning functions onto the first outer conductor, reducing the number of components that require high-precision assembly. While the first outer conductor integrates multiple functions, it eliminates the need for precise alignment between separate first and second outer conductors, thereby reducing manufacturing difficulty and improving ease of assembly.

AI summary
A housing includes a back wall portion and a tubular peripheral wall portion projecting forward from the back wall portion. A second outer conductor includes a tube portion to be passed through an insertion hole of the back wall portion and arranged inside the peripheral wall portion and a base portion to be arranged behind the back wall portion. The first outer conductor includes a bottom portion to be arranged behind the back wall portion to face the base portion. The bottom portion includes a through hole, through which an end part of a dielectric is passed. Mounting portions, to be electrically connected to a circuit board and positioning portions positionable on the circuit board includes project around the through hole in a bottom surface of the bottom portion.
