Universal Plug Prong Locking Bar for Secure Socket Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical plugs with locking structures are not universally compatible with different types of sockets, limiting their versatility and connection reliability.
Innovation Solution
A plug hashing prong with a movable locking bar that can be actuated between locked and loose positions, allowing it to protrude or retract from the plug surface, enabling compatibility with universal sockets through a guided mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking structure with elastic buckle and bayonet is arranged on the electrical plug, then the electrical connection stability is improved, but the adaptability to universal sockets deteriorates
Solution Approach 1:
The locking bar is designed with a guide portion that can adapt to different socket types (universal socket and specialized socket), allowing the same plug structure to achieve reliable locking with multiple socket varieties. The guide portion guides the locking bar to protrude and engage with the jack in universal sockets, while maintaining compatibility with specialized bayonet sockets.
2Reliability
If a locking bar protrudes out of the pin to achieve frictional locking in the jack, then the connection reliability is improved, but the ease of insertion and removal deteriorates
Solution Approach 1:
The locking bar is designed as a movable component that can dynamically change its position between protruding (locked state) and retracted (unlocked state). The guide portion ensures the locking bar moves along a predetermined path, automatically protruding during insertion to engage the jack and retracting during removal to clear the jack, thus maintaining ease of operation while ensuring reliable locking.
3Adaptability or versatility
If the locking bar is guided to move from locked position to loose position, then the universality is improved, but the device complexity increases
Solution Approach 1:
The locking structure is segmented into distinct functional components: the locking bar for engagement, the guide portion for directional control, and the receiving slot for positioning. This segmentation allows each component to perform its specific function independently, achieving universality through the guide portion while keeping the overall structure relatively simple and manageable.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables smooth insertion and removal of the plug from any socket while maintaining a secure electrical connection, enhancing universality and reliability.
Implementation Method 1
a protruding portion is frictionally locked in the jack

AI summary
The present disclosure provides a universal electrical plug, including a shell, a pin, and an actuating component. The pin is configured to be plugged into an adaptive jack of a socket to achieve electrical connection. The pin is fixed to the shell; and one side surface of the pin forms an open surface of the receiving slot. The locking bar can be driven by the actuating component and is guided by a guide portion to move from a locked position to a loose position. When the locking bar is in the locked position, the locking bar at least partially protrudes out of the open surface, and a protruding portion is frictionally locked in the jack. When the locking bar is in the loose position, the locking bar is received in the receiving slot. The present disclosure can be used in conjunction with a universal plug and achieve locking.
