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.

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

Engineering Contradiction:
Improveelectrical contact qualityVSAvoidconnector variants
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
