Terminal Base Covering Structure for Stress-Resistant Electronic Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic components experience stress concentration at the base portion surrounding the protruding terminal, leading to potential destruction or deformation due to external forces.
Innovation Solution
The electronic component features a base portion with a covering portion extending from its outer surface to cover the periphery of the terminal's base end, dispersing stress applied when external forces are exerted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal is embedded in the base portion with one end protruding, then electrical connection is achieved, but stress concentration occurs at the base end of the terminal leading to destruction or deformation
Solution Approach 1:
The base portion is designed with a covering portion that has a different structural configuration compared to the rest of the base. This covering portion specifically reinforces the region around the terminal base end, providing localized stress distribution without altering the overall base structure or terminal configuration.
Solution Approach 2:
The base portion is divided into distinct regions: a covering portion that surrounds the terminal base end and a base body portion that contains the electronic element. This segmentation allows the covering portion to specifically address stress concentration at the terminal base while the base body maintains its primary functions.
2Ease of manufacture
If the base portion structure is simplified, then manufacturing is easier, but stress concentration leads to base portion destruction
Solution Approach 1:
The covering portion and base body portion are integrated as a single unified structure. This merging eliminates the need for separate assembly steps while providing enhanced stress resistance through the covering portion's geometric configuration that distributes stress away from the terminal base end.

AI summary
An electronic component includes a base portion having an accommodating portion that accommodates an electronic element and a terminal. The terminal has a part embedded in the base portion, and one end portion of the terminal protrudes from the base portion toward outside of the base portion. The base portion has a covering portion. The covering portion extends from an outer surface of the base portion and covers at least a part of a periphery of a base end in the one end portion of the terminal.
