Edge Connector Locking Strip for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge plug-in connection systems on printed circuit boards are difficult to assemble correctly, leading to potential loosening due to vibrations, and existing solutions require complex geometries and multiple latching elements, making them unreliable and costly.
Innovation Solution
A plug connection safety device with a separable fastening strip that can be easily assembled by plugging the connector onto the contact strip and then mounting the lock, which secures the edge connector without direct dependency on the connector or contact strip geometry, ensuring high reliability even if assembly is incorrect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple latching elements are used to secure the edge connector, then the connector is secured against loosening, but the assembly becomes more complex and difficult to inspect
Solution Approach 1:
The patent combines multiple latching elements into a single integrated connector lock component. This lock has a U-shaped cross-section that allows it to simultaneously engage with multiple contact strips, providing the security function of multiple latches while simplifying the overall structure into one piece that is easier to assemble and inspect.
Solution Approach 2:
The connector lock serves multiple functions simultaneously: it secures the connector against loosening, provides a visible inspection feature for quality control, and simplifies the assembly process. This multi-functional design resolves the contradiction by making a single component do the work of multiple specialized elements.
2Reliability
If specially designed geometries are required for plug-in connection, then the connection can be secured, but the manufacturing cost and complexity increase
Solution Approach 1:
The invention separates the security function from the connector geometry itself by introducing a distinct connector lock component. This segmentation allows the contact strips and connector to maintain simple, easy-to-manufacture geometries while the separate lock component provides the necessary security through its own specialized geometry, resolving the contradiction between connection security and manufacturing simplicity.
Solution Approach 2:
The connector lock acts as an intermediary element between the connector and the contact strips. Instead of requiring complex geometries on the main connector components, this intermediate lock component provides the specialized geometry needed for secure engagement, simplifying the manufacturing of the primary components while maintaining connection security.
3Reliability
If assembly errors occur in plug-in connection, then the connection may be incorrect, but with multiple latching elements it is difficult to detect assembly errors
Solution Approach 1:
The connector lock incorporates visual indicators that change or become visible when properly assembled. The U-shaped cross-section and specific geometric features provide visual cues that allow operators to easily inspect and verify correct assembly, making assembly errors detectable while maintaining connection integrity.
Solution Approach 2:
The connector lock design provides immediate visual feedback about assembly status. The geometry of the lock and its engagement with the contact strips creates visible indicators that tell the assembler whether the connection is correct, enabling real-time detection and correction of assembly errors while ensuring connection integrity.
