Coaxial Cable Connector Integrated Nut and Inner Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screw-type coaxial cable connectors have poor ground reference connections due to incomplete contact between the nut and inner sleeve with the coaxial cable, leading to loose connections and poor signal transmission performance.
Innovation Solution
A coaxial cable connector design where the nut and inner sleeve are formed as a single part, allowing the inner sleeve to rotate relative to the outer sleeve, ensuring good electrical ground connection with the coaxial cable's braided layer, regardless of the nut's engagement with an externally threaded connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional screw-type coaxial cable connector uses a separate nut and inner sleeve structure, then the connector can be assembled with standard externally threaded connectors, but the ground reference connection becomes poor due to incomplete contact between components
Solution Approach 1:
The patent merges the nut and inner sleeve into a single integrated component called an integrated connector body. This unified structure eliminates the gap and contact issues between separate components, ensuring complete and reliable ground reference connection between the braided shield and the connector while maintaining compatibility with externally threaded connectors
2Ease of operation
If the nut is loosely engaged with the externally threaded connector, then the connector can be easily assembled and disassembled, but the electrical ground connection quality deteriorates
Solution Approach 1:
The integrated connector body incorporates a threaded portion that rotates relative to the outer sleeve, allowing dynamic adjustment during assembly. This rotational mechanism ensures that the inner sleeve portion maintains full contact with the braided shield throughout the engagement process, preserving ground connection quality while enabling easy assembly and disassembly through simple rotational motion
3Reliability
If the inner sleeve does not fully contact the externally threaded connector, then the connector structure remains simple, but the electrical connection reliability becomes poor
Solution Approach 1:
The integrated connector body is pre-configured with the inner sleeve portion positioned to contact the braided shield before engagement with the externally threaded connector occurs. This preliminary positioning ensures that as the threaded portion rotates and engages, the ground reference connection is already established and maintained throughout the assembly process, eliminating alignment precision requirements

AI summary
A coaxial cable connector configured to be mounted to an externally threaded connector, comprising a nut portion having an inner thread configured to engage with an outer thread of said externally threaded connector, an inner-sleeve portion coaxially arranged with said nut and a first sleeve coaxially arranged with said nut, wherein said first sleeve comprises an inner flange radially on an outer wall of said inner-sleeve portion, characterized in that: when said nut is rotated relatively to said first sleeve, said inner-sleeve portion is rotated relatively to said first sleeve.
