Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical signal connectors for coaxial cables often suffer from biased or tilted cylindrical casings during crimping, leading to uneven pressure distribution and potential displacement of the coaxial cable, which affects signal transmission quality and stability.
Innovation Solution
An electrical signal connector design featuring a locknut with an abutment flange, an inner tube with a bearing surface, a cylindrical casing with deformable body portions, and a torque sleeve that allows smooth movement relative to the casing, ensuring even compression and secure engagement without extra accessories, using an elastically deformable plastic material for the casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a crimping tool is used to move the metal barrel relative to the plastic cylindrical casing during assembly, then the engagement between the electrical signal connector and the coaxial cable is tightened, but the cylindrical casing may be biased, affecting signal transmission quality or stability
Solution Approach 1:
The patent introduces guide means (such as guide ribs or guide slots) as intermediary elements between the metal barrel and the plastic cylindrical casing. These guide means prevent the casing from being biased during the crimping process by constraining the movement path of the barrel, thereby ensuring that the tightening force is applied uniformly without causing tilting or displacement that would affect signal transmission quality.
2Ease of operation
If the metal barrel is moved relative to the plastic cylindrical casing to force internal barbed portions into engagement with the braided outer conductor, then the engagement is tightened, but the cylindrical casing may be biased or tilted
Solution Approach 1:
The guide means act as intermediary structures that facilitate the relative movement between the metal barrel and plastic cylindrical casing while maintaining alignment. The guide ribs or guide slots provide a constrained path that allows the barrel to move axially without allowing lateral displacement or tilting, thus ensuring manufacturing precision is maintained during the assembly operation.
Solution Approach 2:
The patent incorporates dynamic elements such as movable guide means or flexible guide structures that adapt during the crimping process. The guide means may include features that allow for controlled deformation or adjustment during assembly, enabling the system to accommodate minor variations in component dimensions while maintaining precise alignment and preventing biasing of the cylindrical casing.

AI summary
An electrical signal connector for assembly with a coaxial cable includes a locknut defining an abutment flange at the front side, an inner tube fastened to the rear side of the locknut opposite to the abutment flange and defining a bearing surface portion for receiving the coaxial cable, a cylindrical casing fastened to the rear side of the locknut around the inner tube and defining a first deformable body portion and a second deformable body portion, a barrel and a torque sleeve attached to the locknut and the cylindrical casing. The barrel defines a front end edge stopped against an inside stop flange of the torque sleeve which can be moved to force a rear inside bearing surface of the barrel over the first deformable body portion and second deformable body portion of the cylindrical casing, thereby tightening up the engagement between the electrical signal connector and the coaxial cable.
