Solution Overview

Problem

Existing screened connectors require different screenings for various cable thicknesses, leading to higher production costs and potential damage during assembly due to the need for tools and additional manufacturing efforts.

Innovation Solution

A screened connector design where the screening is fastened to the outside of the cable's screen braid, allowing for a single screening to be used across different cable diameters, with a crimp sleeve providing a hard counter-stop for secure fastening, and the option to use alternative materials like conductive plastics or metals for the screening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the screening is arranged on the cable for different cable thicknesses, then different screenings are required, but this leads to higher production costs

Engineering Contradiction:

Improveadaptability to different cable diametersVSAvoidproduction costs

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The screening is designed as a universal component that can accommodate different cable diameters. The screening is fastened to the outside of the cable's screen braid rather than being inserted into the cable, allowing a single screening design to work with multiple cable sizes. This eliminates the need for multiple screening variants and reduces production costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the screening is pushed onto the cable during assembly, then assembly is simplified, but tools are required and the cable may be damaged

Engineering Contradiction:

Improveassembly simplicityVSAvoidcable damage during assembly

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of pushing the screening onto the cable from the inside, the invention inverts the assembly approach by fastening the screening to the outside of the cable's screen braid. The screening is attached to the screen braid which is already on the cable, eliminating the need to force the screening onto the cable and preventing damage to the cable insulation.

Inventive Principle:

Principle #13The other way round (Inversion)

3Object-affected harmful factors

If a hard underlay ring is arranged under the screen braid for crimping, then cable damage is avoided, but additional manufacturing effort and costs arise

Engineering Contradiction:

Improvecable damage during crimpingVSAvoidnumber of components

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The invention extracts the protective function from the separate hard underlay ring component and integrates it into the screening structure itself. The screening provides a hard counter-stop surface for crimping directly, eliminating the need for the additional underlay ring component while maintaining cable protection during the crimping process.

Inventive Principle:

Principle #2Taking out (Extraction)
