Plug Connector Release Mechanism for Reusable Conductor Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical plug connectors do not allow for easy and rapid release of an electrical conductor after insertion and clamping, making it difficult to reuse the connector without purchasing a new one.
Innovation Solution
Incorporating a release element, such as a slider or pivot mechanism, that allows the clamping spring to be disengaged from the conductor, either manually or with a tool, enabling easy removal of the conductor from the plug connector, even in cramped spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a retaining device is used to position the clamping spring in an open initial state, then the conductor can be inserted easily, but the conductor cannot be released again from the plug connector
Solution Approach 1:
The plug connector transitions from a static retaining device to a dynamic system with a release element that can change the state of the clamping spring. The release element allows the connector to switch between a latched state (holding the conductor) and an unlatched state (releasing the conductor), enabling repeated use while maintaining easy insertion.
Solution Approach 2:
A release element is introduced as an intermediary component between the user and the clamping spring mechanism. This release element mediates the interaction by providing a controlled way to disengage the latching mechanism, allowing the conductor to be released without requiring destruction or replacement of the entire connector.
2Volume of moving object
If the plug connector is designed with compact dimensions, then the installation space is reduced, but the integration of a release element becomes difficult
Solution Approach 1:
The release element is merged with existing components of the plug connector, such as integrating it into the housing or combining it with the retaining device. This integration allows the release functionality to be added without significantly increasing the overall volume or complexity of the connector, maintaining compact dimensions while enabling conductor release.
3Device complexity
If the release element requires a tool for actuation, then the release mechanism can be simpler, but untrained persons cannot easily release the conductor
Solution Approach 1:
The release element is designed to be actuated directly by the user without requiring external tools. The mechanism allows untrained persons to release the conductor themselves through a simple manual action, such as pressing a button or moving a slider, making the connector user-friendly and accessible to anyone regardless of technical expertise.

AI summary
An electrical plug connector with a plug end surface which is provided for connecting the electrical plug connector to a mating plug connector includes an electrical contact for connecting an electrical conductor to the electrical plug connector. The plug connector includes a spring cage having a clamping spring acting as a pressure spring and a busbar contact region opposite the clamping spring. The plug connector further includes a single-part or multipart connection housing designed to accommodate the contact and to latch the clamping spring in a latching state in an open position. The latching and open position can be brought out of engagement by inserting the conductor. The plug connector further includes a release element which is provided for releasing the electrical conductor from the contact so that the conductor can be removed from the plug connector. The release element is integrated in the plug connector.
