Two-Part Outer Conductor for Coaxial Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high production and logistics costs of coaxial connectors are due to the need for multiple variants to match different coaxial cables' inner and outer diameters, requiring a large number of connectors with varying dimensions to ensure good electrical contact and mechanical stability, leading to increased manufacturing costs.
Innovation Solution
An outer conductor arrangement for coaxial connectors is designed in two parts: a contact component made of tin bronze or its alloy for electrical connection and a connection component made of stainless steel or its alloy for mechanical connection, allowing for separate optimization and use across multiple coaxial cables, with options like soldering, welding, or crimping for assembly, and stamped and bent components for efficient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coaxial connectors are designed with varying dimensions to match different coaxial cables, then good electrical contact and mechanical stability are achieved, but manufacturing costs and logistical complexity increase
Solution Approach 1:
The outer conductor arrangement is divided into two separate components: a contact component with a contact section for mating connectors and a connection component with a connection section for coaxial cables. These components are electrically and mechanically connected at a contact section. This segmentation allows the contact component to be standardized while the connection component can be adapted to different cable types, reducing the number of connector variants needed.
Solution Approach 2:
The contact component is designed with universal applicability to work with different coaxial cable types through the standardized contact section. By separating the contact function from the cable-specific connection function, a single contact component can serve multiple cable configurations, reducing logistical complexity and manufacturing costs.
2Reliability
If multiple variants of coaxial connectors are produced to match different cable diameters, then impedance matching is maintained, but production costs increase
Solution Approach 1:
The outer conductor arrangement is divided into two separate components: a contact component with a contact section for mating connectors and a connection component with a connection section for coaxial cables. These components are electrically and mechanically connected at a contact section. This segmentation allows the contact component to be standardized while the connection component can be adapted to different cable types, reducing the number of connector variants needed.
Solution Approach 2:
The invention allows for parameter changes in the connection component to accommodate different cable diameters and configurations while maintaining the standardized contact component. By adjusting parameters such as the connection section geometry and material properties rather than creating entirely different connector variants, manufacturing complexity is reduced while maintaining proper impedance matching.
