Clip Contact Element for Detachable PCB Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for printed circuit boards are not detachable and occupy excessive space, limiting their versatility and assembly orientation.
Innovation Solution
A clip contact element that can be removably inserted into a recess on the printed circuit board, featuring guide bevel elements and contact lip elements to securely hold a plug contact unit, allowing for a low-profile, detachable connection that can be oriented specifically to accommodate various plug contact units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a detachable connection arrangement is provided, then assembly flexibility and reconfigurability are improved, but the installation space and profile height increase
Solution Approach 1:
The contact element is inserted into a recess in the printed circuit board, with the contact element body positioned inside the recess and only the contact tip protruding. This nesting approach allows the detachable connection arrangement to be compact and low-profile, reducing the installation space while maintaining assembly flexibility.
Solution Approach 2:
The connection arrangement utilizes the vertical dimension by inserting the contact element into a recess, rather than extending horizontally. This dimensional transition reduces the profile height and installation footprint while preserving the detachable connection functionality.
2Shape
If the contact element is fully inserted into the recess, then the profile height is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The contact element is pre-assembled with the plug contact unit before insertion into the recess. This preliminary assembly ensures proper alignment and positioning, reducing the precision requirements during the final insertion step into the printed circuit board.
Solution Approach 2:
The contact element features a resilient body that automatically provides contact force and maintains electrical connection upon insertion. The resilient properties enable self-adjustment and compensation for minor dimensional variations, reducing the stringency of manufacturing precision requirements.
3Reliability
If guide ramp elements and contact lip elements are added, then the secure holding of plug contact unit is improved, but the device complexity increases
Solution Approach 1:
The guide ramp elements and contact lip elements are integrated into a single contact element body, rather than being separate components. This merging reduces the number of parts and assembly steps while maintaining the secure holding functionality through the combined geometric features.
Solution Approach 2:
The contact element has different geometric features (guide ramps, contact lips, resilient sections) at different locations along its length, each optimized for its specific function. This local differentiation provides secure holding and guidance without requiring complex overall structure.
