Socket Actuating Mechanism Lever Tab Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of contacts in a socket connector increases while the height remains unchanged, the existing actuating mechanism fails to drive the moving plate to move a sufficient horizontal distance, leading to unreliable interconnection with IC package balls.
Innovation Solution
A socket connector design featuring a lever with two tabs that are pressed by a lid in sequence to drive a sliding plate to move horizontally, ensuring the plate can achieve a predetermined horizontal movement even with increased contacts, by engaging and disengaging the tabs with the lid at different positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of contacts is increased while the height remains unchanged, then the contact density is improved, but the horizontal movement distance of the sliding plate becomes insufficient
Solution Approach 1:
The lever is segmented into two functional parts: a first tab for initial engagement and a second tab for continued engagement. This segmentation allows the actuating mechanism to achieve greater horizontal movement distance by sequentially engaging different tabs, resolving the contradiction between increased contact density and sufficient sliding plate movement.
2Device complexity
If the second operating lever is used to drive the moving plate, then the actuating mechanism is simplified, but the moving plate moves a shorter distance than required
Solution Approach 1:
The lever transitions from a static single-tab design to a dynamic two-tab configuration where the engagement point changes during actuation. The lever rotates and shifts engagement from the first tab to the second tab, dynamically adapting to provide the required horizontal movement distance while maintaining actuating mechanism simplicity.
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
This design allows for reliable interconnection of contacts with IC package balls by ensuring the sliding plate moves the necessary horizontal distance, maintaining effective contact even with increased contact numbers without altering the socket height.
Implementation Method 1
a lever having a first tab and a second tab which are pressed by the lid in sequence so as to urge the sliding plate to move during rotation of the lever

AI summary
A socket connector includes a socket body, a sliding plate movably mounted upon the socket body, a plurality contacts received in the socket body and the sliding plate, and an actuating mechanism. The actuating mechanism includes a lid moving upwardly and downwardly between a first position away from the socket body and a second position close to the socket body, and a lever having one mating bar with at least a first tab and a second tab to be pressed by the lid so as to push the sliding plate moving.
