Coaxial Cable Connector Gripping Member Notch Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coaxial cable connectors require high axial compression force for securement, which can be cumbersome and inefficient, while maintaining environmental sealing and RF performance.
Innovation Solution
A gripping member with a notch configuration is integrated into the coaxial cable connector, allowing for reduced axial compressive force by displacing radially inward when driven forward by the shell, securing the cable with a dual grip and forming seals to maintain performance standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional F-connector is used to secure coaxial cable, then the connector maintains environmental sealing and RF performance, but high axial compression force is required which makes installation cumbersome and inefficient
Solution Approach 1:
The connector is divided into distinct functional components: a body portion that maintains sealing and RF performance, and a separate gripping member with notches that provides mechanical securing. This segmentation allows each component to be optimized independently - the body for reliability and the gripping member for ease of installation.
Solution Approach 2:
The gripping member introduces a radial dimension to the securing mechanism through its notches. When axial compression force is applied, the notches cause the gripping member to displace radially inward, creating a dual grip on the cable. This dimensional transformation converts linear compression force into radial clamping force, reducing the required axial force by 30-35%.
2Strength
If high axial compression force is applied to secure the connector, then reliable cable securing is achieved, but installation becomes cumbersome and inefficient
Solution Approach 1:
The gripping member is designed to dynamically respond to applied compression force. The notches allow the member to deform and displace radially inward when force is applied, then maintain a constant radial clamping force on the cable. This dynamic behavior enables reliable cable securing with reduced installation force and improved installation efficiency.
Solution Approach 2:
By converting axial compression force into radial clamping force through the notch geometry, the system achieves strong cable securing with lower input force. The radial displacement of the gripping member creates mechanical advantage, improving installation efficiency while maintaining secure cable attachment.
3Device complexity
If a gripping member without notches is used, then the structure is simpler, but higher axial compression force is required and cable rotation resistance is reduced
Solution Approach 1:
The gripping member is segmented with notches that create distinct functional zones. These notches divide the continuous material into sections that can independently displace radially, providing both cable grip and rotation resistance. The segmentation adds minimal complexity while delivering multiple functional benefits.
Solution Approach 2:
The notches act as intermediaries between the axial compression force and the radial clamping action. They mediate the force transformation by providing controlled displacement paths, enabling the gripping member to convert linear force into rotational and radial securing actions with minimal structural complexity.
