Coaxial Cable Connector With Direct Grounding Sheath Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial cable connectors require manual preparation of the outer conductive grounding sheath, which is time-consuming, inconsistent, and poses safety and health risks, as well as potential signal interference.
Innovation Solution
A coaxial cable connector design that allows attachment without flaring or folding the braided outer conductive grounding sheath, using a post to electrically contact the outer conductor and a gripping member to secure the cable, enabling consistent and safer installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer conductive grounding sheath is manually flared and folded back, then grounding continuity is established, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The connector body is divided into distinct functional zones: a cable receiving area with a jacket stop to hold the cable, and a contact area with a post to establish electrical contact with the outer conductor. This segmentation allows the connector to perform multiple functions (mechanical retention and electrical grounding) simultaneously without requiring manual preparation of the braided sheath.
Solution Approach 2:
The invention extracts the requirement for manual flaring and folding of the braided outer conductor from the installation process. The connector design accepts the cable in its original state and establishes grounding continuity through the post contacting the outer conductor directly, eliminating the need for the installer to manually manipulate the braided material.
2Reliability
If the braided outer conductive grounding sheath is manually prepared, then electrical continuity is achieved, but consistency between different installers is compromised
Solution Approach 1:
The connector performs self-alignment and self-contact functions. The post is positioned within the connector body to automatically contact the outer conductor when the cable is inserted, eliminating the need for installer skill or manual manipulation. This ensures consistent electrical continuity regardless of which installer performs the connection.
3Reliability
If the outer conductor is manually flared and folded, then grounding is established, but small fragments may break off causing electrical shorts
Solution Approach 1:
The invention removes the manual flaring and folding steps that generate harmful fragments from the installation process. By designing the connector to contact the outer conductor in its original braided state, the process eliminates the mechanical stress that causes small pieces to break off and potentially cause electrical shorts.
4Reliability
If manual preparation of the outer conductor is performed, then grounding continuity is established, but safety and health risks to the installer increase
Solution Approach 1:
The connector performs the grounding function automatically upon cable insertion, eliminating the need for the installer to manually handle and manipulate the braided outer conductor. This self-service mechanism removes the installer from direct contact with potential hazards such as sharp edges or small fragments that could cause injury.

AI summary
A coaxial cable connector for attachment to an end of a coaxial cable is disclosed. The coaxial cable connector has a body having a forward end and a rearward end. An internal surface extends between the forward end and the rearward end defining a longitudinal opening and with a cable receiving area proximal the rearward end and a jacket stop proximal the forward end. A post is positioned in the body proximal the forward end and has a first end and a second end with a bore extending therebetween. An insulator is movably disposed in the bore of the post and has a through-passage, and a movement limiter. A gripping member is disposed within the longitudinal opening of the body proximal the rearward end and provides a gripping action as the gripping member axially moves toward the forward end of the body.
