Solution Overview

Problem

Connectors with cable outlets angled 90° from the insertion direction often cause cable kinking, leading to deteriorated transmission properties and reduced reliability in industrial environments.

Innovation Solution

A two-part cable sleeve with rotating parts allows for variable cable routing without kinking, enabling the cable to be directed in multiple angles by fixing the first part in multiple positions and rotating the second part, which can be fastened in various positions to accommodate different outlet directions, preventing cable kinking and maintaining transmission quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cable outlet is bent at an angle of 90° to the axis of the plug-in direction and held by overmolding or mechanical cable guide sleeve, then the cable outlet direction is fixed, but the cable is often kinked during turning, leading to deterioration in transmission properties and reduced reliability

Engineering Contradiction:
Improvecable routing flexibilityVSAvoidtransmission properties
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cable guide is divided into two separate parts: a first part (cable guide sleeve) that guides the cable entry, and a second part (cable outlet guide) that directs the cable outlet. This segmentation allows independent positioning of each guide section, enabling the cable to be routed at various angles without kinking while maintaining fixed outlet directions for reliable connections.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a fixed cable guide structure is used to maintain cable outlet direction, then the connector structure is simple, but the cable must be routed in a fixed direction which may cause kinking

Engineering Contradiction:
Improvecable routing optionsVSAvoidcable guide structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable guide incorporates a rotatable first part (cable guide sleeve) that can be rotated to different angular positions around the connector axis. This dynamic element allows the cable entry direction to be adjusted adaptively, providing multiple routing options without requiring a completely complex reconfigurable structure, thus balancing versatility with structural simplicity.

AI summary

The connector (10) has a cable sleeve (20) comprising two sleeve parts (30, 40), which include longitudinal axes. One of the sleeve parts is fixable relative to the connector in two different positions rotated around one of the longitudinal axes. The other sleeve part is fixable relative to the connector in two various positions rotated around the other longitudinal axis. The longitudinal axes are positioned to each other in one of the fixed positions of the cable sleeve in a non-zero angle.
