Connector Holding Bracket Fixation Strength via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face challenges in achieving strong fixation on circuit boards due to the limited number of fixed terminals, which affects the reliability and stability of the electrical connection.
Innovation Solution
The connector design includes a holding bracket with both first and second fixed terminals, where the second terminal is maximally spaced from the first, and is exposed along the housing, enhancing the attachment strength by insert molding and providing additional fixation points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If only one fixed terminal is provided at each corner of the housing, then the device complexity is reduced, but the fixation strength on the circuit board deteriorates
Solution Approach 1:
The holding bracket is divided into multiple segments including a first holding bracket and a second holding bracket, each with separate fixed terminals. This segmentation allows multiple fixed terminals to be distributed across different locations on the circuit board, increasing fixation strength without creating a single complex terminal structure
Solution Approach 2:
The second fixed terminal is extended from the side plate portion of the holding bracket, utilizing the lateral dimension of the bracket structure. This dimensional extension allows the second fixed terminal to be positioned at maximum distance from the first fixed terminal, optimizing the fixation geometry and strength distribution across the circuit board mounting surface
2Stability of the object's composition
If the second fixed terminal is provided at maximum distance from the first fixed terminal, then the fixation stability is improved, but the device complexity increases
Solution Approach 1:
The first holding bracket and second holding bracket are integrated into a single unified holding bracket structure that is provided for the housing by insert molding. This merging combines multiple functional elements (multiple fixed terminals, side plate portions, bottom plate portions) into one integrated component, improving fixation stability while avoiding the complexity of assembling multiple separate parts
