Plug Connector Pulling Aid with Integrated Shield Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical plug connectors with pulling aids face challenges in integrating a shield support while maintaining ease of removal, particularly in cramped spaces, where the pulling aid may collide with the cable shield, risking damage to the connection.
Innovation Solution
The integration of an electrically conductive section within the pulling aid serves as both a grip area for removal and a shield support, spatially separating gripping areas from shield contact points, allowing for reliable contact and preventing accidental cable pulling, with the conductive section fixed in a form-fitting manner and optionally using non-positive fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pulling aid is added to enable easy removal of the connector, then ease of operation is improved, but the risk of collision with the cable shield increases
Solution Approach 1:
The pulling aid is divided into functionally distinct zones: a gripping area for user interaction and a shield support area for cable contact. This segmentation allows each zone to perform its specific function without interfering with the other, resolving the contradiction between ease of removal and collision risk.
Solution Approach 2:
Different areas of the pulling aid are assigned different properties: the gripping area has geometric features for finger engagement, while the shield support area provides a flat, stable surface for cable contact. This local differentiation enables the pulling aid to simultaneously facilitate removal while protecting the cable shield.
2Ease of operation
If the pulling aid is designed with a large gripping area for easy grasping, then ease of operation is improved, but the space available for shield support is reduced
Solution Approach 1:
The pulling aid utilizes three-dimensional space by extending in multiple directions from the connector housing. The gripping areas are positioned laterally while the shield support area extends in a different spatial orientation, allowing both functions to coexist without compromising area availability.
Solution Approach 2:
The pulling aid structure is segmented into distinct functional zones that are spatially separated. The gripping areas are located in regions optimized for finger contact, while the shield support area is positioned in a separate zone, ensuring sufficient space for both functions.
3Ease of manufacture
If the pulling aid is made as a separate component for flexibility, then ease of manufacture is improved, but device complexity increases
Solution Approach 1:
The pulling aid is integrated with the connector housing as a single molded component. This merging eliminates the need for separate assembly steps and additional fastening elements, reducing device complexity while maintaining manufacturing flexibility through integrated design.
Solution Approach 2:
The pulling aid serves multiple functions simultaneously: it provides gripping areas for removal, supports the cable shield, and integrates with the connector housing structure. This multi-functionality reduces the need for separate components, simplifying the overall device while maintaining ease of manufacture.
