Circular Connector Modular Locking Ring Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circular electrical connectors require separate manufacturing lines for secured and unsecured versions, leading to high production costs due to the need for distinct securing mechanisms, such as spring-like arrangements, which complicates the production process and increases costs.
Innovation Solution
A modular locking system combining a bayonet lock with a detachable locking ring featuring a resilient element, allowing for secure and cost-effective assembly and disassembly, where the locking mechanism can be engaged or disengaged using axial or radial pressure, depending on the variant, enabling the production of a single connector with or without secondary locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If securing means are permanently attached to prevent unintentional release, then reliability is improved, but device complexity and production costs increase due to separate manufacturing lines
Solution Approach 1:
The securing means is divided into a modular locking ring that can be separately attached to the connector housing. This allows the locking function to be added or removed without redesigning the entire connector, enabling a single manufacturing line to produce both secured and unsecured versions by simply including or excluding the locking ring component.
Solution Approach 2:
The connector housing is designed with a universal interface that can accommodate both secured and unsecured configurations. The same basic connector structure serves multiple functions depending on whether the locking ring is attached, eliminating the need for separate product lines and reducing manufacturing complexity while maintaining reliability when needed.
2Reliability
If spring-like arrangements are used for locking, then reliability is improved, but manufacturing costs increase due to additional components and assembly steps
Solution Approach 1:
The locking ring is designed as a simple, inexpensive component that can be easily manufactured and attached. Rather than using complex spring mechanisms, the solution employs a straightforward mechanical locking ring with basic engagement features, significantly reducing component costs and simplifying the manufacturing process while maintaining adequate locking reliability.
3Speed
If bayonet lock is used for fast connection, then speed of connection is improved, but protection against unintentional opening is reduced
Solution Approach 1:
The solution merges the fast bayonet lock mechanism with an additional modular locking ring that provides secondary security. The bayonet lock maintains its rapid connection capability while the added locking ring engages with the housing to prevent unintentional opening, combining the advantages of both quick connection and enhanced security in a single system.
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
This solution allows for rapid, precise, and reliable connections while reducing production costs by enabling the same connector to be manufactured with or without secondary locking, maintaining size integrity and preventing unintentional opening.
Implementation Method 1
a resilient element, preferably made of plastic, is pushed over a flange of the cable box and locked. After the plug-in connection has been closed, the resilient element engages in a recess in the cap ring and prevents unintentional opening.

AI summary
The invention relates to an electrical plug connection, preferably a circular plug connection having a first circular plug connector and a fastening ring. The fastening ring is rotatably arranged on the first circular plug connector. Furthermore a second circular plug connector, a primary lock and a secondary lock having a locking ring that can be placed onto the second circular plug connector are provided. The secondary lock is formed by the fastening ring and the locking ring being in locking engagement when the first circular plug connector and the second circular plug connector form the plug connection.
