Connector With Direct Locking and Rotational Pre-Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors with triangular buckles for locking and unlocking lack a pre-ejection function, making it inconvenient to swiftly and effectively separate connectors when the rotation direction is incorrect, and existing bidirectional unlock connectors do not provide a swift separation mechanism.
Innovation Solution
A connector design incorporating an insulated body, inner and outer shells, snap ring, fasteners, ejector, and elastic elements, where the outer shell can be rotated clockwise or counterclockwise to drive a cam surface, pushing an ejector to pre-eject the mating connector, allowing bi-directional unlocking and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connectors use triangular buckles that slide against each other to lock, then the connectors can be stably connected, but the connectors cannot be swiftly and effectively separated when rotation direction is incorrect
Solution Approach 1:
The ejector is pre-positioned within the outer shell and can be rapidly activated by rotating the outer shell in either direction. This preliminary positioning allows the ejector to immediately push the mating connector upon activation, providing a swift separation mechanism that does not depend on correct rotation direction for unlocking first
Solution Approach 2:
The ejector acts as an intermediary mechanism between the user's rotation action and the separation of connectors. When the outer shell is rotated, the ejector is driven to move forward and physically push the mating connector, mediating the separation process and enabling effective disconnection even when rotation direction was incorrect
2Ease of operation
If connectors are designed to unlock in both directions, then convenience is improved, but a pre-ejection function for swift separation is still lacking
Solution Approach 1:
The ejector mechanism is pre-positioned and ready for immediate action. Upon rotating the outer shell in either clockwise or counterclockwise direction, the ejector is rapidly driven forward to push the mating connector, providing a swift pre-ejection function that accelerates the separation process beyond mere unlocking
Solution Approach 2:
The system transitions from a static locking mechanism to a dynamic separation mechanism. The ejector can be rapidly activated by rotation in either direction, transforming the outer shell from a simple connector component into an active driver that propels the ejector forward for swift separation
Applied Scientific Principles
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 swift and effective separation of connectors by allowing rotation in both directions for unlocking and utilizing the pre-ejection function to efficiently disengage the connectors, improving usability and convenience.
Implementation Method 1
The first elastic element abuts against the ejector to provide an elastic force for the ejector to recover to its original position
Implementation Method 2
The second elastic element abuts against the outer shell to provide an elastic force for the outer shell to recover to its original position

AI summary
A connector with a direct locking and a rotational pre-ejection function is provided. The connector includes an insulated body, a plurality of terminals, an inner shell, an outer shell, a snap ring, a plurality of fasteners, an ejector, a first elastic element, and a second elastic element. The outer shell has a cam surface, the ejector has an abutting portion, and the abutting portion is in contact with the cam surface. When the connector and a mating connector are inserted into each other, snap bodies of the fasteners and fastener bodies of the mating connector can be snapped into each other to be directly locked. When the connector and the mating connector are to be separated from each other, the snap bodies of the fasteners and the fastener bodies of the mating connector can be separated from each other to be directly unlocked.
