Coaxial Cable Connector Locking Structure Against Pull Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coaxial cable connectors often loosen when pulled, leading to unstable signal transmission due to inadequate securement mechanisms.
Innovation Solution
A coaxial cable connector design featuring a metal inner sleeve with elastic portions and wings, an outer sleeve with an engaging bump, and a nut with a threaded portion, which securely engages with a threaded surface on an electronic device, ensuring stable signal transmission by preventing the coaxial cable from loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional coaxial cable connector is used, then the structure is simple, but the connector loosens when pulled, resulting in unstable signal transmission
Solution Approach 1:
The connector is divided into multiple functional components: an outer sleeve for engagement, an inner sleeve with elastic portions for securing the coaxial cable, and a nut for threaded attachment. This segmentation allows each component to perform its specific function, with the elastic portions providing continuous securing force to prevent loosening while maintaining overall structural organization
Solution Approach 2:
The elastic portions of the inner sleeve are designed to be deformable, allowing them to dynamically adapt to the coaxial cable and maintain constant securing pressure. This dynamic property ensures the connector remains tightly secured during pull forces, preventing loosening while the flexible material absorbs mechanical stress
2Stability of the object's composition
If a secure engagement mechanism is added to prevent loosening, then the connector stability improves, but the device complexity increases
Solution Approach 1:
The inner sleeve with elastic portions is nested within the outer sleeve, and both are secured by the nut. This nested arrangement provides multiple levels of engagement and securing mechanisms, ensuring stable attachment to the threaded surface while organizing components in a compact, space-efficient configuration that minimizes overall complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The connector effectively prevents the coaxial cable from loosening, maintaining stable signal transmission and secure attachment to electronic devices, thereby enhancing the reliability of signal transmission.
Implementation Method 1
a second inner ring, comprising a ring portion and a plurality of elastic portions, wherein one end of each of the plurality of elastic portions is respectively connected with the ring portion, and the other end of each of the plurality of elastic portions comprises a fifth outer flange

AI summary
A coaxial cable connector comprises an inner sleeve comprising a first and second outer flange; metal inner sleeve comprising a second inner ring having a ring portion and plurality of elastic portions and a first inner ring having a second inner flange and plurality of wings; an outer sleeve comprising a fourth inner flange and engaging bump; and a nut comprising a first inner flange and threaded portion adapted to engage with an electronic device. One end of the plurality of elastic portions is connected with the ring portion and the other end comprises a fifth outer flange. One end of the plurality of wings is connected to the second inner flange and the other end to the ring portion. When the outer sleeve moves toward the nut, the engaging bump presses and enables the fifth outer flange to move toward the outer surface of the inner sleeve.
