Solution Overview

Problem

Existing cable connector assemblies face high production costs and compromised high-frequency performance due to the lack of a fixing structure for core wires, requiring complex assembly processes and the removal of the inner shielding layer.

Innovation Solution

A cable connector assembly with an inner mold integrally formed on the core wires to fix them at predetermined positions, eliminating the need for external clamps and reducing the length of the inner shield layer, while maintaining electrical connectivity through conductive terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If no fixing structure is used for core wires, then the assembly process is simple, but the core wires cannot be positioned and soldered efficiently, leading to high production cost and complex process

Engineering Contradiction:

Improveassembly process simplicityVSAvoidproduction cost

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent combines the core wire fixing function with the inner shield layer by integrally forming the inner mold on the core wires. This merging eliminates the need for separate fixing structures while enabling efficient positioning and soldering, thus reducing production cost without complicating the assembly process

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The inner mold is integrally formed on the core wires before the final assembly, preliminarily positioning and fixing the core wires at predetermined positions. This preliminary action enables subsequent soldering operations to be performed efficiently without requiring additional positioning steps during assembly

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the inner shield layer is peeled off extensively, then the core wires can be accessed for soldering, but the high frequency performance of the cable connector is compromised

Engineering Contradiction:

Improveaccess to core wires for solderingVSAvoidhigh frequency performance

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The core wires are preliminarily positioned and fixed on the inner mold before assembly, allowing soldering operations to be performed with minimal peeling of the inner shield layer. This preliminary positioning enables access to core wires while preserving the shielding integrity and maintaining high frequency performance

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The inner mold provides localized fixing at predetermined positions, allowing selective access to specific core wires for soldering without requiring extensive peeling of the inner shield layer. This local quality approach maintains the shielding effectiveness while enabling necessary electrical connections

Inventive Principle:

Principle #3Local quality
