Self-Locking Latch Connector With Integrated Securing Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latching connectors require elastic deformation and additional latch pins to secure components, which is not feasible for all component geometries and can lead to mechanical stress-induced detachment.
Innovation Solution
A self-locking latching connector design featuring a uniform latching hook with an integrated securing section, such as an elastically deformable spring tongue, that engages in the latch opening without the need for separate latch pins, ensuring secure engagement without deformation or mechanical play.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If latch pins with elastic deformation are used to secure the latching connection, then the connection is locked against reversal, but the device complexity increases and additional components are required
Solution Approach 1:
The patent combines the latching hook and securing section into a single integrated component that forms one piece with the first component. This merging eliminates the need for separate latch pins and latching recesses, reducing device complexity while maintaining the self-locking function through the interaction between the hook end, securing section, and latch opening
Solution Approach 2:
The latching hook is designed to perform multiple functions: it guides the components together, engages behind the second component for mechanical connection, and the securing section simultaneously latches into the latch opening to prevent reversal. This multi-functionality eliminates the need for dedicated latch pins
2Reliability
If elastic deformation is required for latching pins to engage, then the connection can be locked, but the adaptability to different component geometries is reduced
Solution Approach 1:
The patent eliminates the requirement for elastic deformation by changing the engagement parameters. The latching hook and securing section are designed with specific geometric parameters that allow direct engagement with the latch opening without requiring material deformation, thereby increasing adaptability to different component geometries while maintaining connection security
3Reliability
If separate latch pins and latching recesses are used, then the connection is secured, but the space required for the connection increases
Solution Approach 1:
The patent merges the latching hook and securing section into a single integrated structure that forms one piece with the first component. This consolidation reduces the volume required for connection components by eliminating separate latch pins and their associated recesses, while the securing section still effectively latches into the latch opening to prevent component detachment
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
The solution provides a space-saving, self-locking connection that maintains component alignment under mechanical stress, eliminating the need for additional components and ensuring secure engagement without deformation, suitable for various component geometries.
Implementation Method 1
the securing section is configured as an elastically deformable spring tongue
Implementation Method 2
due to a spring-back of the spring tongue the securing section can also latch in the latch opening at the same time

AI summary
A latching connector for connecting a first component to a second component, wherein a latching hook is formed on the first component and a latch opening is formed on the second component, and wherein, in order to connect the first component to the second component, the latching hook passes through the latch opening and engages behind the second component with a hook end. The latching hook has a securing section which adjoins the latching hook on a side facing away from the hook end and which can be latched in the latch opening.
