Rotational Locking Plug Connector for Vibration-Resistant Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug-in connectors lack a robust and reliable locking mechanism that can be miniaturized, making them prone to disconnection under harsh environmental conditions such as vibrations and shock-loads.
Innovation Solution
A rotational locking mechanism is introduced, where a locking member is moved from a locking to a non-locking position and back, using a spring or magnetic force, to securely engage and disengage latching elements, allowing for a secure connection that can be easily integrated into small connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to plug-in connectors to improve reliability under harsh conditions, then connection stability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is integrated into the connecting parts themselves, merging the locking function with the connector structure. The first connecting part includes a locking member that directly engages with the second connecting part, eliminating the need for separate locking devices and reducing overall system complexity while maintaining reliable connection under harsh conditions.
2Reliability
If a rotational locking mechanism is introduced to secure connections, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The locking member is designed to be movable between different positions (locked and unlocked) along the longitudinal axis. This dynamic design allows the locking mechanism to be easily engaged and disengaged by simple axial movement, maintaining ease of operation while providing secure rotational locking when engaged. The locking member can rotate to engage with corresponding features on the second connecting part, ensuring reliable connection.
3Reliability
If existing locking mechanisms are used in plug-in connectors, then connection security is improved, but manufacturing complexity increases
Solution Approach 1:
The locking mechanism is segmented into distinct functional elements: a locking member on the first connecting part and corresponding engagement features on the second connecting part. This segmentation allows each component to be manufactured independently using standard machining processes, simplifying production. The locking member can be a separate insert or integrated into the first connecting part, providing manufacturing flexibility while ensuring secure connection.

Function Achieved in This Case
The solution provides a reliable and secure connection that can withstand harsh conditions, ensuring the connector remains locked without requiring excessive force, suitable for both miniaturized and large connectors, and can be easily integrated into various types of connectors.
Implementation Method 1
a spring element (16) configured for pressing the locking member (14) towards a mating end (17) of the first connecting part (1) into a locking position
Implementation Method 2
A rotational locking mechanism is introduced, where a locking member is moved from a locking to a non-locking position and back, using a spring or magnetic force

AI summary
A plug-in connector comprising a first connecting part and a second connecting part is described, the first connecting part being configured for being mated with the second connecting part in a mating direction. The first connecting part comprises at least one latching element configured for engaging with at least one counterlatching element of the second connecting part when the first connecting part is mated with the second connecting part, and a locking member movably arranged in the first connecting part, wherein the locking member is configured for locking an engagement between the at least one latching element and the at least one counterlatching element in a locking position of the locking member. The first connecting part comprises a forced guidance configured for enforcing a rotational motion of the locking member when the locking member is moved relative to the at least one latching element. The second connecting part is shaped and configured for interacting with the locking member such that a rotational motion of the locking member relative to the first connecting part is enforced when the first connecting part is mated with the second connecting part, wherein the rotational motion comprises moving the locking member from the locking position to a non-locking position and back to the locking position, with the at least one latching element being configured for engaging with the at least one counterlatching element when the locking member is in the non-locking position.
