Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coaxial cable connectors require a tool for tight engagement, which can lead to undesired un-tight connections if not used carefully, complicating the operation and ensuring secure signal transmission.
Innovation Solution
A coaxial cable connector design featuring a connection head and sleeve assembly with a metal collar that compresses a buffering section to enhance engagement, allowing for secure and effortless connection without the need for external tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tool is used to clamp the clamp barrel and coaxial cable together, then tight engagement between the connector and cable is achieved, but the operation becomes complicated and requires careful handling to avoid un-tight engagement
Solution Approach 1:
The connector is designed with a self-clamping mechanism where the clamp barrel automatically engages and secures the coaxial cable through its own structural features (such as inwardly directed edges or barbs) without requiring an external tool. The cable insertion itself triggers the clamping action, making the system self-servicing and eliminating the need for careful tool operation.
Solution Approach 2:
The connector is divided into functional segments: the clamp barrel with engagement features, the cable receiving section, and the securing mechanism. This segmentation allows each part to perform its specific function independently, with the clamp barrel's structured edges automatically gripping the cable outer jacket as it is inserted, providing reliable tight engagement without tool assistance.
2Reliability
If a conventional clamp barrel structure is used, then connection to the distributor is achieved, but the engagement tightness cannot be ensured without careful tool operation
Solution Approach 1:
The clamp barrel is designed with localized engagement features such as inwardly directed edges, barbs, or gripping structures at specific positions where cable contact is needed. These local structural modifications provide enhanced grip and tight engagement without requiring complex overall connector design, maintaining simplicity while ensuring reliable connection.
Solution Approach 2:
The clamp barrel is designed to dynamically adapt to the cable during insertion. The structured edges or barbs flex or engage automatically as the cable is inserted, creating a self-adjusting clamping action that ensures tight engagement without requiring external tool intervention or complex pre-adjustment mechanisms.
Applied Scientific Principles
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 design ensures a secure and easy operation for coaxial cable connectors, providing a simplified assembly process and maintaining tight engagement with the coaxial cable, thereby improving the reliability of signal transmission.
Implementation Method 1
the sleeve assembly is then acted upon by a force applied by a tool to drive the metal collar frontward against the contact section for breaking and separating the retention section from the sleeve to further move frontward along a surface of the buffering section. Due to a constraint imposed by the metal collar, the buffering section is compressed downward to enhance tightness of engagement between the coaxial cable and the connector.

AI summary
A coaxial cable connector includes a connection head and a sleeve assembly coupled to the connection head. The sleeve assembly includes a tube, a sleeve, and a metal collar. The sleeve assembly receives a coaxial cable to insert therein from a rear end thereof in such a way that an insulator layer of a front end of the coaxial cable is set substantially flush with a front end of the tube and the sleeve assembly is then acted upon by a force applied by a tool to drive the metal collar frontward against the contact section of the sleeve for breaking and separating the retention section of the sleeve from the sleeve to further move frontward along a surface of the buffering section of the sleeve. Due to a constraint imposed by the metal collar, the buffering section is compressed downward to enhance tightness of engagement between the coaxial cable and the connector.
