Universal Plug Locking Bar for Reliable Socket Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical plugs with locking structures are not compatible with universal sockets, limiting their universality and connection reliability.
Innovation Solution
A universal electrical plug design featuring a pin with a receiving slot, a movable locking bar, and an actuating component that allows the locking bar to protrude out of the pin for frictional locking in a universal socket, enhancing compatibility and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking structure with elastic buckle is arranged on the electrical plug, then the connection reliability is improved, but the adaptability deteriorates because it cannot be paired with a universal socket
Solution Approach 1:
The locking bar is designed to be movable between a received state (when plugged into a specific socket) and a protruding state (when plugged into a universal socket). This allows the same plug structure to adapt to different socket types while maintaining locking capability, thus achieving multi-functionality and universality without sacrificing connection reliability
2Reliability
If a locking structure is added to the electrical plug, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The locking bar is nested within the pin body, with its receiving slot formed on the surface of the pin. When not in use, the locking bar is received within the pin structure; when needed, it protrudes to engage with the socket. This nesting approach integrates the locking mechanism into the existing pin structure rather than adding a separate complex locking device, thus improving reliability while minimizing additional complexity

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 plugging and locking into universal sockets without obstruction, improving universality and connection reliability.
Implementation Method 1
the guide portion acts on the locking bar to bend the thinned portion
Implementation Method 2
maintain the locking bar in the locked position to cause a protruding portion of the locking bar to be frictionally locked in the jack

AI summary
The present disclosure provides a universal electrical plug, including a shell, a pin, a guide portion, a movable locking bar, 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; the pin is provided with a receiving slot; and one side surface of the pin forms an open surface of the receiving slot. The locking bar can be in a loose or locked position. The actuating component is connected to the locking bar and is configured to drive the locking bar to move and maintain the locking bar in the locked position to cause a protruding portion of the locking bar to be frictionally locked in the jack. The present disclosure can be used in conjunction with a universal socket and achieve locking.
