Power Connector Anti-Disengagement Toggle Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power plugs often disconnect due to external forces, leading to poor contact or complete disconnection, causing accidental power outages in critical equipment like data centers and medical devices, necessitating a reliable and secure connection mechanism.
Innovation Solution
An anti-disengaging mechanism for power connectors featuring a toggle ring, pull rod, and swingable seizing piece that securely engages and disengages the power plug, ensuring continuous power supply by aligning or misaligning the seizing piece with the plug pin, preventing accidental disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple power plug connection is used, then the device structure is simple and easy to manufacture, but the connection reliability deteriorates when external force is applied
Solution Approach 1:
The seizing piece is designed to swing between engaged and disengaged positions dynamically. It automatically adjusts its state based on the insertion of the power plug, swinging to the engaged position when the plug is inserted and to the disengaged position when the plug is removed, providing adaptive connection reliability without complex control systems
Solution Approach 2:
The pull rod acts as an intermediary mechanism that transmits the swinging motion of the seizing piece to the power plug connection. When the seizing piece swings, it drives the pull rod to move along its length, which in turn drives the power plug to swing between engaged and disengaged states, mediating the connection force distribution
2Reliability
If a secure locking mechanism is added to prevent disconnection, then the connection reliability improves, but the ease of operation deteriorates
Solution Approach 1:
The mechanism performs self-service through automatic state transitions. When the power plug is inserted, the seizing piece automatically swings to the engaged position and locks the connection. When the plug is removed, it automatically swings to the disengaged position and releases the connection, eliminating the need for manual locking or unlocking operations
Solution Approach 2:
The seizing piece is pre-positioned to swing into the engaged state before any external force can cause disconnection. This preliminary engagement action ensures the connection is secured in advance, preventing accidental disconnection while maintaining ease of operation through automatic activation

AI summary
A power connector with an anti-disengaging mechanism that has a power socket that includes a metal terminal. The power socket is shaped to receive a plug pin of a power plug. A seizing piece that includes a through hole. The seizing piece is located so that the plug pin of the power plug travels through the through hole in order to come in contact with the metal terminal. A pull rod is arranged so that when the pull rod is in a first position, the pull rod tilts the seizing piece so as to lock the plug pin in contact with the metal terminal. When the pull rod is in a second position, the seizing piece releases the plug pin. A toggle ring is rotated by a user to drive the pull rod to slide between the first position and the second position. A first portion of the seizing piece is within a supporting groove inside the power connector. A second portion of the seizing piece is inserted into a driving groove of the pull rod. Movement of the pull rod is controlled by the toggle ring.
