Socket with Through Electrode Sheet for Pin Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IC sockets risk damaging the lower end of contact pins during attachment of the wiring board, as the exposed pins can be caught by electrodes, leading to potential bending or breaking.
Innovation Solution
A socket design featuring a sheet member with through electrodes that faces the bottom surface, allowing the upper end of the through electrode to contact the pin lower end and the lower end to contact the wiring board, preventing direct contact and damage.

Engineering Contradiction Analysis
1Reliability
If the contact pin lower end is exposed from the bottom surface for electrical connection, then electrical connection functionality is improved, but the contact pin becomes vulnerable to damage during wiring board attachment
Solution Approach 1:
A sheet member with through electrodes is introduced as an intermediary component between the contact pin lower end and the wiring board electrodes. The sheet member's through electrode makes contact with the pin lower end and transmits the electrical connection, while preventing direct contact between the pin and wiring board electrodes, thus protecting the pin from damage during attachment
Solution Approach 2:
The sheet member is disposed in a horizontal plane facing the bottom surface, creating a new dimensional layer. This sheet member intercepts the harmful interaction in the vertical attachment direction by providing a protective interface at the bottom surface level, separating the contact pin protection function from the electrical connection function

AI summary
A socket electrically connects a first electric component and a second electric component, including: a base part in which a through hole extending through the base part from a top surface to a bottom surface in a vertical direction is formed; a contact pin inserted to the through hole such that a pin lower end is exposed from the bottom surface, and configured such that, when in use, a pin upper end makes contact with the first electric component; and a sheet member including a through electrode extending therethrough in the vertical direction, disposed at the base part in a state where the sheet member faces the bottom surface, and configured such that, when in use, an upper end of the through electrode makes contact with the pin lower end and a lower end of the through electrode makes contact with the second electric component.
