Solution Overview

Problem

Existing electrical signal connectors for coaxial cables require complex and labor-intensive installation procedures, which can lead to adverse effects on signal transmission quality if not properly aligned and compressed.

Innovation Solution

A deformable cylindrical casing with a slidably engaged barrel that radially compresses and deforms to securely fasten the coaxial cable, eliminating the need for additional compression tools and simplifying the installation process by pinching the cable between the casing and core tube.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a compression tool is used to move the end-cap relative to the outer tubular member to compress the outer tubular member and force the barbed portion into engagement with the cable, then the connection stability is improved, but the installation procedure becomes complicated and labor-intensive

Engineering Contradiction:

Improveconnection stabilityVSAvoidinstallation procedure

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The connector is designed to perform the compression function automatically during the insertion process. When the coaxial cable is inserted into the connector body, the cable's outer jacket and shield are automatically compressed by the barbed portion and retention members without requiring external compression tools or additional manual operations. The structure uses the insertion action itself to trigger the compression and securing mechanism.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The invention combines multiple functions into a single integrated connector body: the outer tubular member serves as both the protective housing and the compression element; the barbed portion is integrated directly into the connector body rather than being a separate component; and the retention members are built-in features that automatically engage with the cable during insertion. This eliminates the need for separate compression tools and simplifies the installation to a single insertion action.

Inventive Principle:

Principle #5Merging (Combining)

2Manufacturing precision

If the outer tubular member is biased relative to the coaxial cable during insertion, then the cable positioning is improved, but the alignment precision becomes difficult to control

Engineering Contradiction:

Improvecable alignmentVSAvoidinsertion effort

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The connector body incorporates localized guiding features and retention members at specific positions to provide precise alignment only where needed. The barbed portion and retention members are strategically positioned to engage with specific parts of the cable (outer jacket and shield) at critical locations, ensuring proper alignment without requiring the entire insertion process to be precisely controlled. This localized approach to alignment reduces overall insertion complexity.
