Connector Locking Device with Keyed-Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector locking devices are costly, require modification or replacement of existing connectors, and are cumbersome in network environments, leading to undesirable data transfer interruptions and security issues.
Innovation Solution
A self-releasing and keyed-release connector locking device that includes a locking tongue support, a retaining mechanism, and a release arm or key-accessible mechanism to securely engage and release the locking tongue, allowing for secure data transfer without the need for additional tools or replacement of connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a built-in locking pin in the female connector is used, then security against unauthorized removal is improved, but device complexity and cost increase due to requiring removal and replacement of female connectors
Solution Approach 1:
The locking mechanism is extracted from the female connector and placed entirely on the male connector. The locking tongue and retaining mechanism are integrated into the male connector, eliminating the need to modify female connectors while achieving the same security function.
Solution Approach 2:
A retaining mechanism acts as an intermediary between the locking tongue and the terminal body. This intermediary component provides the security function by engaging with the terminal body to prevent removal, while allowing controlled release through the release arm mechanism.
2Reliability
If locking pins or screws are used in modified connectors, then security is improved, but ease of operation deteriorates due to requiring screwdrivers or similar tools for cable removal
Solution Approach 1:
The release arm is designed to be manually operable without tools. The operator can directly manipulate the release arm to disengage the retaining mechanism from the terminal body, enabling tool-free cable removal while maintaining security during normal operation.
Solution Approach 2:
The retaining mechanism transitions from a static locked state to a dynamic released state through the action of the release arm. This dynamic capability allows the system to maintain security during normal use while enabling easy removal when needed, resolving the contradiction between security and ease of operation.
3Reliability
If bulky casing or housing devices are used to surround connectors, then security against unintentional removal is improved, but device complexity and space requirements increase
Solution Approach 1:
The locking function is extracted from bulky external casings and integrated directly into the connector structure itself. The locking tongue and retaining mechanism are built into the male connector, eliminating the need for additional housing devices while providing the same protective function.
Solution Approach 2:
The locking mechanism components (locking tongue, retaining mechanism, release arm) are merged into a single integrated assembly on the male connector. This consolidation provides security functionality without requiring separate bulky casing devices, reducing overall device complexity.
