Metal Terminal Segmentation for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic components with metal terminals face significant challenges in maintaining vibration resistance, especially when subjected to external forces, as the stress concentrates on the metal terminals, leading to potential separation from conductor pads on the circuit board, particularly for components of large mass.
Innovation Solution
The electronic component design features metal terminals with a first planar part connected to external electrodes using conductive bonding material and a second planar part positioned across a clearance, fixed to the component body with adhesive, providing enhanced mechanical strength and minimizing vibration resistance drop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal terminals are used to provide mechanical strength in mounted state, then the electronic component can be securely mounted on circuit board, but stress concentrates on metal terminals causing separation from conductor pads under vibration
Solution Approach 1:
The metal terminal is divided into multiple planar parts (first planar part connected to external electrode, second planar part facing component body) that are fixed at different locations. This segmentation distributes the stress concentration points and allows each part to bear specific loads, preventing single-point failure during vibration
Solution Approach 2:
The invention transitions from a single-plane connection to a multi-dimensional fixation structure. The metal terminal extends in multiple directions with planar parts positioned at different spatial locations, creating a three-dimensional stress distribution pattern that enhances vibration resistance while maintaining mounting strength
2Weight of moving object
If electronic component of large mass is used, then the component can provide required electrical capacity, but vibration resistance drops due to stress concentration on metal terminals
Solution Approach 1:
By segmenting the metal terminal into multiple planar parts fixed at different locations, the structure distributes the weight-induced stress across multiple attachment points rather than concentrating it on a single terminal, thereby maintaining vibration resistance despite large component mass
Solution Approach 2:
The invention creates a composite structure combining the metal terminal, adhesive bonding material, and component body. This composite system leverages the high strength of metal terminals for electrical connection while using the adhesive to distribute mechanical stress, enabling large mass components to maintain vibration resistance

Function Achieved in This Case
This design significantly improves the vibration resistance of electronic components, even for those of large mass, by distributing stress through the adhesive and conductive bonding, reducing the likelihood of metal terminal separation during mounting.
Implementation Method 1
the second planar part of the metal terminal is positioned in such a way that it faces at least partially, across a clearance, another face adjoining the one face of the component body, while being fixed to the component body by adhesive provided in the clearance
