Plug Connector Pull Strip Lock Head Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connectors require excessive force for unlocking and often necessitate the use of auxiliary tools due to the difficulty in pressing the lock head, making the unlocking operation cumbersome.
Innovation Solution
A plug connector design featuring a lock head with an L-shaped elastic arm and a pull strip that drives the lock head down when pulled backward, allowing for easy locking and unlocking, with the lock head automatically returning to its original position when the force is released.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional lock head is used on the plug connector, then the locking function is achieved, but the insertion force becomes excessive and the unlocking operation becomes difficult requiring auxiliary tools
Solution Approach 1:
The patent introduces a pull strip as an intermediary component that mediates between the user and the lock head. The pull strip transmits the user's pulling force to the lock head's elastic arm, enabling easy unlocking without requiring direct manipulation of the lock head or auxiliary tools. This intermediary mechanism solves the contradiction by making the unlocking operation simple while maintaining the reliable locking function.
Solution Approach 2:
The lock head employs an elastic arm that can dynamically change its position between locked and unlocked states. The elastic arm is designed to be flexible enough to be pushed down by the pull strip during unlocking, yet rigid enough to maintain reliable locking engagement. This dynamic flexibility allows the lock head to adapt to different operational states, resolving the contradiction between reliable locking and easy unlocking.
2Reliability
If a traditional lock head is used on the plug connector, then the locking function is achieved, but the insertion force required becomes excessive
Solution Approach 1:
The elastic arm of the lock head is designed to be flexible and dynamic, allowing it to be easily pushed down during insertion by the holding-down structure. This flexibility reduces the insertion force required while maintaining the reliability of the locking function when engaged. The elastic arm can deform under insertion force and then maintain the locked position, resolving the contradiction between low insertion force and reliable locking.
Solution Approach 2:
The patent changes the physical parameters of the locking mechanism by using an elastic material for the lock head's arm. This material parameter change allows the lock head to deform elastically during insertion, reducing the force required, while still providing sufficient mechanical strength to maintain reliable locking engagement. The parameter change from rigid to elastic material resolves the contradiction between insertion force and locking reliability.
3Reliability
If the lock head is designed to be pressed downward for unlocking, then the locking function is maintained, but the operation becomes difficult requiring auxiliary tools
Solution Approach 1:
The pull strip serves as a simple intermediary lever that converts a pulling motion into the downward pushing force needed to unlock the lock head. This intermediary mechanism simplifies the unlocking operation to a single pulling action without requiring complex mechanisms or auxiliary tools, while maintaining the reliable locking function. The pull strip acts as a force amplifier that makes the unlocking operation simple.
Solution Approach 2:
The lock head's elastic arm is designed to automatically return to its locked position after being pushed down by the pull strip, eliminating the need for additional mechanisms to reset the lock. The elastic recovery provides self-service functionality that simplifies the overall unlocking mechanism while maintaining reliable locking, reducing device complexity.

AI summary
A plug connector for easy locking and unlocking is disclosed, including a base, a signal transmission module, a lock head, a cover and a pull strip. The plug connector of the present invention employs a holding-down structure of the pull strip, which can drive an edge block of the lock head to go down and further force the lock head to go down by pulling the pull strip backward. When releasing the pull strip, the lock head can automatically go up. Therefore, in the present invention, the pull strip can control the lock head, thereby completing the locking and unlocking work. The locking and unlocking way of the present invention is safe, effective and convenient.
