Cable Terminating Assembly With Insulating Cutting Blades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable terminating assemblies face challenges in miniaturization and cost reduction while ensuring secure termination and preventing short circuits, particularly in cutting and insulating wires within connector housings.
Innovation Solution
A cable terminating assembly featuring a wire manager with electrically insulating cutting blades formed from materials like nanometer fiber reinforced resin or glass fiber reinforced resin, which cut and insulate wires during insertion, eliminating the need for additional insulation and enhancing the assembly's compactness and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cutting blades and insulation components are used, then secure wire termination and short circuit prevention are achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the cutting blade and insulation components into a single integrated piece. The insulating material forms both the cutting edge and the insulation barrier, eliminating the need for separate cutting blades and insulation components. This merging reduces device complexity while maintaining the reliability of wire termination and short circuit prevention.
Solution Approach 2:
The insulating material component serves multiple functions simultaneously: it acts as a cutting blade for trimming wires, provides electrical insulation to prevent short circuits, and offers mechanical support for wire positioning. This multi-functionality reduces the number of components needed while ensuring secure termination.
2Reliability
If multiple separate components are used for cutting and insulating, then reliable wire termination is achieved, but manufacturing cost increases
Solution Approach 1:
By merging the cutting blade and insulation components into one integrated insulating material piece, the patent reduces the number of manufacturing steps, assembly operations, and quality checks required. This single-component approach lowers manufacturing costs while maintaining reliable wire termination through the combined cutting and insulation functions.
3Length of moving object
If traditional cutting blades are used, then wire cutting is achieved, but additional insulation components are required increasing assembly complexity
Solution Approach 1:
The insulating material is designed to integrate the cutting blade function directly into the insulation structure. The cutting edge is formed as part of the insulating material itself, so that one component performs both cutting and insulation functions, eliminating the need for additional insulation assembly steps.

AI summary
A cable terminating assembly for terminating a cable having a wire includes a wire manager having an end face facing in an insertion direction and a connector housing with a reception opening receiving at least a part of the wire manager. The end face holds the wire in a predetermined position along the insertion direction. The connector housing has a cutting blade formed by an electrically insulating material. The cutting blade cuts the wire upon insertion of the wire manager into the connector housing.
