Electrical Component Socket Link Stabilization Under High Reaction Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sockets for electrical components face issues with deflection and displacement of the link mechanism when a large reaction force is applied, leading to insufficient pressing force and incomplete operation.
Innovation Solution
A socket design that includes a depression mechanism with a swing lever and depression member to stabilize the leading end part of the opening/closing link mechanism, ensuring stable operation and uniform pressing force even under high reaction forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the link mechanism is configured with base end parts connected to the socket main body and operating member, then the opening/closing body can be actuated to press the IC package, but deflection or displacement occurs at the leading end part when large reaction force acts on the opening/closing body
Solution Approach 1:
A depression member is introduced as an intermediary component between the leading end part of the link mechanism and the socket main body. This depression member receives the reaction force from the contact pins and transmits it to the socket main body, preventing direct transmission of large reaction forces to the link mechanism's leading end part, thereby eliminating deflection and displacement issues
2Reliability
If the opening/closing body presses the IC package with a large number of contact pins, then electrical connection is achieved, but the reaction force causes biased or insufficient pressing force
Solution Approach 1:
The depression member serves as a mediator that distributes the reaction force from multiple contact pins uniformly across the socket main body structure. This prevents localized stress concentration that would cause biased pressing, ensuring uniform pressing force is maintained across all contact points while achieving reliable electrical connection
3Device complexity
If the link mechanism operates without depression of the leading end part, then the structure is simpler, but the mechanism becomes incomplete when large reaction force acts on the opening/closing body
Solution Approach 1:
The depression member is designed as a simple L-shaped component that engages with the leading end part of the link mechanism. This minimalistic intermediary structure provides the necessary support and force distribution function without adding significant complexity to the overall mechanism, maintaining operational completeness even under large reaction forces
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 socket achieves reliable and uniform pressing of electrical components with a sufficient force by stabilizing the link mechanism, preventing deflection and displacement, and simplifying the configuration by reducing the operating range of the depression mechanism.
Implementation Method 1
an operating member provided in the socket main body in a vertically movable manner and urged upward
Implementation Method 2
an IC package arranged on the socket main body is pressed against an elastic force of the contact pins, and terminals of the IC package and the contact pins are elastically brought into contact with each other
