Coaxial Cable Fixing Assembly for Simultaneous Conductor Attachment

Solution Overview

Problem

The existing fixing devices for coaxial cables require complex processes to connect both the central and external conductors to a substrate, involving separate steps for each conductor, which complicates the fixing method.

Innovation Solution

A fixing device with first and second electrode portions, each having connection and fixing portions, that can be coupled and simultaneously attached to the cable and substrate, allowing for simultaneous connection and fixation of both conductors in a single process by cutting off the coupling portion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate fixing processes are used for the central conductor and external conductor, then each conductor can be securely connected to the substrate, but the fixing process becomes complex and time-consuming

Engineering Contradiction:

Improveconnection reliabilityVSAvoidfixing process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the fixing of the central conductor and external conductor into a single integrated fixing device. The first electrode portion connects to the central conductor while the second electrode portion connects to the external conductor, and both are fixed to the substrate simultaneously through a single fixing process, eliminating the need for separate fixing operations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fixing device is designed with multi-functionality to handle both the central conductor and external conductor connections in one operation. The device includes multiple electrode portions and fixing portions that can simultaneously perform connection and fixation functions for different conductors, reducing overall process complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate fixing processes are used for the central conductor and external conductor, then each conductor can be securely connected to the substrate, but the fixing time increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidfixing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines the fixing of the central conductor and external conductor into a single integrated fixing device. The first electrode portion connects to the central conductor while the second electrode portion connects to the external conductor, and both are fixed to the substrate simultaneously through a single fixing process, eliminating the need for separate fixing operations.
