Modular Locking Device for Plug Connectors on Mounting Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for plug connectors do not facilitate a simple and secure connection between systems of plug connectors on mounting rails, particularly when combining different types of connectors like electrical and optical-fiber connectors.
Innovation Solution
A modular locking device system comprising housing bodies with coupling elements and fixing jigs that allow plug connectors to be securely coupled and fixed to a mounting rail, enabling the connection of multiple plug connectors with different internal configurations, and a locking mechanism with passive and active parts for stable inter-system contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual plug connectors are strung together without a unified housing structure, then assembly flexibility is improved, but connection stability and secure contact between systems deteriorate
Solution Approach 1:
The patent combines multiple individual plug connectors into a unified housing body that accommodates multiple contact elements. This merging approach maintains assembly flexibility through modular design while improving connection stability by providing a single secure mounting interface on the mounting rail, preventing inadvertent break in contact between systems.
2Reliability
If a locking device is added to secure plug connectors on mounting rails, then connection stability is improved, but device complexity increases
Solution Approach 1:
The locking device integrates the securing function directly into the housing body structure, combining the housing and locking mechanisms into a unified component. This approach provides secure connection stability while avoiding the complexity of separate locking devices by embedding the locking functionality within the housing itself.
3Adaptability or versatility
If coupling elements are provided on housing bodies to connect multiple plug connectors, then modularity is improved, but manufacturing complexity increases
Solution Approach 1:
The housing body is designed with universal coupling elements that can connect multiple plug connectors of different types and configurations. This multi-functional design enables high modularity and adaptability while simplifying manufacturing by using standardized coupling interfaces rather than custom connection mechanisms for each connector type.

AI summary
A latching device for a first system of plug connectors, which are fastened to a first mounting rail, and a second system of plug connectors, which are fastened to a second mounting rail, includes a passive latching part and an active latching part. When the active latching part is latched to the passive latching part, the first mounting rail and the second mounting rail are connected to each other, and the plug connectors located on the first mounting rail and the second mounting rail are brought into contact with each other.
