Electrical Connector Terminal Stability via Limiting Bumps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors experience terminal displacement when connected to a circuit board due to unfixed terminals exposed from the connector body.
Innovation Solution
The electrical connector design includes a connector body with terminal slots featuring an accommodating recess and limiting bumps, which restrict terminal movement by positioning the terminals within the slots and preventing upward displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminals are exposed from the connector body for connection, then connection accessibility is improved, but terminal stability deteriorates causing displacement
Solution Approach 1:
The terminal structure is divided into multiple segments: the terminal body within the connector, the exposed connecting end part for connection, and the bent connecting members that provide flexibility. This segmentation allows the terminal to be both accessible for connection and stable through the distributed structure of bent connecting members
Solution Approach 2:
The terminal incorporates bent connecting members that can dynamically bend and deform to accommodate connection forces while maintaining overall stability. The dynamic flexibility of the bent members allows the terminal to absorb stress without displacing from its position
2Stability of the object's composition
If terminals are fixed within the connector body, then terminal stability is improved, but connection accessibility deteriorates
Solution Approach 1:
The connecting end part of the terminal is extracted and exposed from the connector body, allowing external connection while the terminal body remains fixed within the connector. This extraction provides the necessary accessibility without compromising the stability of the terminal body
3Stability of the object's composition
If multiple bent connecting members are used to prevent displacement, then terminal stability is improved, but device complexity increases
Solution Approach 1:
The terminal body and bent connecting members are merged into a single integrated terminal structure, eliminating the need for separate components. This merging reduces assembly complexity while maintaining the stability benefits of multiple bent connecting members
