Vibration-Resistant Electronic Component Mounting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic components mounted on dynamic objects, such as vehicles, experience vibrations that can lead to contact failures between terminals and terminal metal fittings, causing electrical disconnection.
Innovation Solution
A mounting structure for electronic components that includes a housing with a chamber and a terminal chamber, along with a locking mechanism using engaging parts on the base and housing members to secure the component, maintaining electrical connection and resisting vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic component is mounted on a dynamic object, then the electronic component can be used in moving applications, but vibrations cause contact failure between terminal and terminal metal fitting
Solution Approach 1:
The housing is divided into multiple members (casing member and base member) that are assembled together to form the housing structure. This segmentation allows for integrated locking mechanisms and engaging parts to be built into the assembly structure, providing vibration resistance while maintaining adaptability for dynamic object mounting
Solution Approach 2:
The locking mechanism is merged with the housing structure itself, where engaging parts are integrated into the casing member and base member. This combination ensures that the locking function is built-in rather than added separately, providing reliable electrical connection stability while maintaining versatility for dynamic applications
2Reliability
If a locking mechanism is added to prevent vibration-induced contact failure, then electrical connection stability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is merged with the housing assembly structure, where engaging parts are integrated into the casing member and base member rather than being separate components. This merging reduces overall device complexity while maintaining electrical connection stability against vibrations
Solution Approach 2:
The engaging parts are nested within the housing members themselves, with the locking mechanism embedded in the assembly structure. This nesting approach allows the locking function to be incorporated without adding external complexity, maintaining reliability while keeping the device structure compact and simple

AI summary
A mounting structure of an electronic component includes an electronic component, a housing member, a counterpart terminal, and at least one locking mechanism. The electronic component includes: an electronic component main body; a housing formed by assembling a casing member in which a chamber for the electronic component main body is formed and a base member to which the electronic component main body is attached; and a terminal exposed from the chamber to outside of the housing. The housing member includes a housing space including: a first chamber that accommodates the housing; and a second chamber that accommodates a terminal. The counterpart terminal is fitted into the second chamber and electrically coupled to the terminal. The locking mechanism maintains the accommodation state of the electronic component to the housing member by engaging a first engaging part and a second engaging part.
