Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-current plug connectors for vehicle on-board electrical systems face challenges in compatibility with diverse installation spaces and require enhanced vibration resistance and secure mounting confirmation.
Innovation Solution
A plug connector design featuring a sleeve with a receiving space and contact springs, a displaceable locking bolt, and a plug casing lock with a cable guide that allows the electric line to exit perpendicularly, along with a plug casing cap for secure locking, enabling adaptability to various installation spaces and ensuring correct mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the plug connector uses a conventional straight-line cable guide design, then the structure is simple, but the compatibility with diverse installation spaces is poor
Solution Approach 1:
The cable guide is designed to branch off perpendicularly from the longitudinal axis of the plug connector, changing the cable exit direction from linear to angular. This dimensional change in the cable guide structure enables adaptation to diverse installation spaces while maintaining structural simplicity through the use of standard perpendicular branching geometry
2Reliability
If the plug connector uses a locking mechanism with multiple locking elements, then the vibration resistance is improved, but the installation space requirement increases
Solution Approach 1:
The locking mechanism combines a locking bolt with sliding contact on contact springs and a plug casing lock with positive engagement, merging multiple locking functions into an integrated system. This consolidation achieves high vibration resistance while optimizing the use of available installation space through functional integration rather than separate distributed locking elements
3Ease of operation
If the plug connector uses a displaceable locking bolt with contact springs, then the contact force adjustment is improved, but the device complexity increases
Solution Approach 1:
The locking bolt is designed to displace automatically along the longitudinal axis, utilizing the spring force from contact springs to adjust and maintain optimal contact force. This self-adjusting mechanism eliminates the need for external actuators or complex control systems, achieving ease of operation through automatic self-regulation while keeping the overall device complexity manageable

AI summary
A plug connector, particularly a high-current plug connector, is provided that includes at least one electrical contact part having a sleeve with a receiving space on an inner side for receiving a plug-in contact that is inserted along a longitudinal axis of the plug connector. The electrical contact part further includes at least one contact spring attached to the inner side of the sleeve that is in sliding contact with a locking bolt capable of being guided in the sleeve between a first end position and a second end position. The plug connector includes a plug casing accommodating the contact part having at least one cable guide branching off essentially perpendicularly to the longitudinal axis of the plug connector. An electric line is attached to the contact part being guidable from the plug casing in a direction essentially perpendicular to the longitudinal axis of the plug connector.
