Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial cable connectors face challenges in providing strong mechanical and electrical connections that are easy for non-technicians to achieve, while also minimizing radio frequency leakage and noise.
Innovation Solution
The use of biasing members that apply axial and radial forces to create a secure ground connection and allow for a push/pull connection between a connector and adapter portion, while preventing direct paths for radio-frequency signals through the biasing portion to the center conductor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If threaded interfaces with swivel cable connectors are used, then strong mechanical and electrical connections are achieved, but the connection becomes difficult for non-technician users to achieve
Solution Approach 1:
The connector uses a dynamic push/pull interface where the connector is pushed onto the adapter to connect and pulled to disconnect, replacing static threaded interfaces. This dynamic approach maintains strong mechanical connection during operation while dramatically simplifying the connection and disconnection process for end users.
Solution Approach 2:
The patent replaces the mechanical threading system with a spring-loaded biasing mechanism. The biasing member provides automatic engagement force when the connector is pushed onto the adapter, eliminating the need for manual threading while maintaining secure mechanical connection through elastic mechanical principles.
2Ease of operation
If simple push/pull connection is used, then ease of operation for non-technicians is improved, but mechanical connection strength may be compromised
Solution Approach 1:
The biasing member automatically provides the necessary engagement force when the connector is pushed onto the adapter. The spring-loaded mechanism self-regulates to maintain optimal contact pressure between the connector and adapter, ensuring strong mechanical connection without requiring user intervention or complex assembly procedures.
Solution Approach 2:
The biasing member creates periodic contact forces through its elastic deformation cycle. As the connector is pushed onto the adapter, the biasing member compresses and stores energy, then maintains continuous periodic engagement force to sustain strong mechanical connection throughout the operational lifecycle.
3Object-affected harmful factors
If biasing members with spaces are used, then radio-frequency leakage is reduced, but device complexity increases
Solution Approach 1:
The biasing member features locally optimized spaces strategically positioned to block RF leakage paths from the outer conductor to the center conductor. Rather than uniformly complex structure throughout, only specific regions contain spaces oriented to interrupt RF signal paths, maintaining simplicity elsewhere while achieving RF shielding effectiveness.
Solution Approach 2:
The spaces in the biasing member, which could potentially allow RF leakage, are strategically configured to actually block RF paths. The spaces create discontinuities in the RF signal path from the outer conductor to the center conductor, converting what might be harmful gaps into beneficial RF shielding features that reduce electromagnetic interference.

Function Achieved in This Case
This configuration ensures a secure and easy-to-use connection that reduces radio-frequency noise and leakage, maintaining signal integrity and facilitating proper signal transmission.
Implementation Method 1
the biasing members may be configured to be separated by spaces that may be configured to allow the biasing members to elastically deform radially inwardly
Implementation Method 2
the biasing portion may be configured to prevent a direct, line of sight path through a space in the biasing portion from an outside of the biasing portion to a longitudinal centerline of the biasing portion so as to prevent a direct path through the spaces for radio-frequency signals from outside the connector assembly to a center conductor of a cable connected by the connector assembly
