Connector with Insulated Terminals Preventing ESD
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric connectors face issues with electrostatic discharge (ESD) damage to electronic components and inefficient assembly due to exposed conduction terminals and increased horizontal distance between terminals, leading to higher manufacturing costs and material wastage.
Innovation Solution
A connector design featuring an insulative body with a tongue panel and shielding shell, where first conduction terminals have a flat contact portion, bending, fixing, and welding portions connected end-to-end, and second conduction terminals with elastic contact portions, allowing for reduced exposure and assembly via a continuous metal band, with recessed slots for secure fixation and reduced terminal spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conduction terminals are exposed at the front end of the tongue panel for electrical connection, then electrical connection is facilitated, but electrostatic discharge occurs between the terminal and steel casing, damaging electronic components
Solution Approach 1:
A plastic coating layer is applied on the surface of the conduction terminal's contact portion, serving as an intermediary between the metal terminal and the external environment. This coating provides electrical insulation while maintaining electrical conductivity through surface conduction, thereby preventing electrostatic discharge from reaching the steel casing and damaging electronic components.
Solution Approach 2:
A thin plastic coating film is formed on the conduction terminal surface through electrostatic spraying. This thin film structure provides insulation protection against electrostatic discharge while allowing the terminal to maintain its mechanical flexibility and electrical functionality for proper contact connection.
2Ease of manufacture
If conduction terminals are bent and extended from one side of the metal band, then assembly is simplified, but horizontal distance between neighboring terminals increases, lowering material utilization rate and increasing manufacturing cost
Solution Approach 1:
The conduction terminal structure is designed to extend in the vertical direction (thickness direction of metal band) rather than horizontally. The contact portion bends upward from the metal band surface, forming a three-dimensional structure that allows terminals to be closely spaced horizontally while maintaining adequate contact area, thereby improving material utilization without compromising assembly.
Solution Approach 2:
Instead of bending terminals horizontally from the metal band edge, the design inverts the bending direction to extend vertically upward from the band surface. This inversion allows the metal band to maintain continuous horizontal structure for efficient material usage, while the vertical extension provides the necessary contact functionality.
