Rotary Plug Fixing Mechanism for Communication Rack Power Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power distribution units in communication equipment racks lack a fixing mechanism for power plugs, leading to connection failures due to accidental contact with other plugs and inconvenient installation/removal, especially in narrow spaces with limited visibility.
Innovation Solution
A rotary-opening/closing type plug fixing mechanism that securely fixes power plugs by rotating in one direction, allowing single-handed removal and easy visual inspection of connection states, featuring a U-shaped tension part, snap protrusion, and rotation guide to prevent slipping and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable tie fixing means is used to fix power plugs, then the contact force of terminals is improved, but the ease of operation deteriorates due to inconvenient installation and removal
Solution Approach 1:
The patent applies a rotatable plug fixing means that can dynamically change its state between locked and unlocked positions. The fixing means rotates to engage with the power plug during installation and can be rotated back for easy removal, transforming a static cable tie system into a dynamic mechanical locking system that maintains reliability while improving operability.
Solution Approach 2:
The plug fixing means is divided into separate functional components: a fixing body with rotating mechanism, engagement protrusions, and a release mechanism. This segmentation allows the fixing function to be independent from the power distribution unit, enabling easy attachment and detachment while maintaining secure fixation during operation.
2Volume of moving object
If the power distribution apparatus is installed in the corner of the communication equipment rack, then the space utilization is improved, but the ease of operation deteriorates due to limited work space and visibility
Solution Approach 1:
The rotatable plug fixing means allows operators to easily access and manipulate power plugs by rotating the fixing mechanism, compensating for the limited accessibility caused by corner installation. The rotational motion provides mechanical advantage and improves dexterity in confined spaces.
Solution Approach 2:
The plug fixing means is designed to be self-evident in its locked state, with visual indicators that show whether the power plug is securely fixed or can be removed, eliminating the need for close inspection and allowing operation from a distance.
3Device complexity
If a conventional fixing means is used without rotation capability, then the device complexity is reduced, but the ease of operation deteriorates due to inability to easily remove power plugs in narrow spaces
Solution Approach 1:
The rotatable fixing mechanism adds minimal complexity while dramatically improving operability. The rotation capability is achieved through a simple pin-and-slot or cam-based mechanism that requires only a quarter-turn motion, providing easy removal without complex tools or procedures.
Solution Approach 2:
The fixing means incorporates curved or rounded surfaces that facilitate rotational motion and provide ergonomic grip areas, allowing operators to easily rotate and release the power plugs even in narrow spaces with limited hand movement room.

AI summary
A power distribution apparatus with a rotary-opening/closing type plug fixing device for a communication equipment rack is provided. The power distribution apparatus prevents poor connection resulting from accidentally touching other power plugs by fixing the power plug with the plug fixing device which rotates in one direction, and allows the separation of the plug fixing device with only one hand when separating the power plug, thereby enabling users to conveniently separate the power plug even in a narrow space.
