PCB Power Socket via Screw Thread Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional power sockets for Printed Circuit Boards (PCBs) often require excessive force for installation, risking structural and electrical damage, and necessitate tight tolerances that are costly and difficult to achieve, limiting their compatibility and usability.
Innovation Solution
A power socket system comprising a receptacle and plug that interface via a screw and thread mechanism, allowing insertion through a via on the PCB without excessive force and accommodating tolerance variations, providing electrical continuity across layers without the need for restrictive tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional power sockets are installed using excessive force, then secure electrical connectivity is achieved, but the structural and electrical integrity of the PCB is damaged
Solution Approach 1:
The power socket is divided into two separate components: a receptacle that is inserted into the PCB via and a plug that is screwed into the receptacle. This segmentation allows the receptacle to be installed with minimal force, preserving PCB integrity, while the plug provides secure electrical connectivity through threading.
Solution Approach 2:
The receptacle is pre-installed into the PCB via before the plug is attached. This preliminary action creates a prepared interface that guides the plug insertion, ensuring proper alignment and reducing the force needed during final assembly, thereby protecting the PCB from damage.
2Manufacturing precision
If traditional power sockets are installed with tight tolerances, then precise electrical alignment is achieved, but manufacturing costs and difficulty increase
Solution Approach 1:
The plug incorporates threaded engagement that allows for dynamic adjustment during assembly. This threading mechanism compensates for tolerance variations in the via and receptacle, maintaining precise electrical alignment without requiring extremely tight manufacturing tolerances, thereby reducing fabrication costs and difficulty.
Solution Approach 2:
The design changes the engagement parameter from a rigid press-fit relationship to a threaded screwing relationship. This parameter change allows for tolerance compensation through rotational adjustment, achieving precise electrical alignment with more relaxed manufacturing tolerances and lower production costs.
