Floatable Pusher Test Socket Cover for Variable Package Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test sockets face challenges in reliably connecting electronic packages of varying thickness due to accumulated tolerance issues, leading to inconsistent electrical connections and limited adaptability to different package thicknesses, with contacts becoming distorted over time.
Innovation Solution
A test socket design featuring an insulative base with pivotally mounted cover, incorporating a pusher with an opening and a lid with through holes, and elastic members between them, allowing for adjustable thickness and maintaining reliable contact through spring-mediated positioning of the electronic package.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the thickness of the lid, pusher and base is exactly controlled to assemble the electronic package in a certain height, then the electrical connection can be reliable, but it is difficult to control the dimension and generates accumulated tolerance leading to contact compression issues
Solution Approach 1:
The patent introduces an elastic member between the pusher and lid, transforming the rigid fixed-thickness structure into a dynamic adjustable one. The elastic member allows the lid to move vertically relative to the pusher, compensating for dimensional variations in the electronic package while maintaining reliable electrical connection through spring-mediated pressure regulation.
2Manufacturing precision
If the socket is designed for a certain package thickness, then the assembly is precise, but it cannot apply to packages with different thickness
Solution Approach 1:
The elastic member enables the socket to adapt to different package thicknesses by changing the compression parameter. When packages of varying thickness are inserted, the elastic member compresses to different extents, automatically adjusting the lid position to maintain proper contact pressure regardless of the specific package thickness.
3Device complexity
If the cover is rigid with fixed thickness, then the structure is simple, but the contacts become distorted and contact points change after long-time usage
Solution Approach 1:
The elastic member serves as a cushioning element that absorbs and distributes compression forces before they reach the contacts. This beforehand cushioning prevents excessive or insufficient contact pressure, reducing contact distortion and maintaining stable contact points during long-time usage.
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 design enables reliable electrical connections for electronic packages of different thicknesses by maintaining proper contact alignment and preventing excessive or insufficient contact pressure, thus enhancing manufacturing ease and adaptability.
Implementation Method 1
Between the pusher and the lid have a plurality of elastic members for making the lid moveably with respect to the pusher
