USB 3.0 Plug Connector Two-Row Soldering Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of USB 3.0 connectors with two rows of terminals is complicated due to tight packing of soldering sections, leading to low production rates and high manufacturing costs, as well as risks of short circuits from excess solder.
Innovation Solution
A plug connector design featuring soldering sections arranged in two transverse rows, with first terminals using through-hole technology and second terminals using surface mount technology, reduces soldering section density and facilitates easier assembly, while separate insulative housing and mounting bracket components simplify manufacturing.

Engineering Contradiction Analysis
1Speed
If two rows of terminals are packed tightly to achieve USB 3.0 transmission speed, then transmission speed requirement is met, but soldering sections become difficult to solder and short circuit risk increases
Solution Approach 1:
The patent applies dimensional change by arranging soldering sections in two transverse rows instead of a single row, effectively distributing the terminals across different spatial dimensions. This dimensional redistribution increases the spacing between adjacent soldering sections, making them easier to solder while maintaining the required transmission speed capability through proper terminal arrangement.
2Speed
If two rows of terminals are packed tightly to achieve USB 3.0 transmission speed, then transmission speed requirement is met, but production rate decreases and manufacturing cost increases
Solution Approach 1:
By transitioning from a single-row to a two-row transverse arrangement of soldering sections, the patent optimizes the spatial utilization of the connector body. This dimensional reorganization allows for more efficient manufacturing processes, including automated soldering operations, thereby increasing production rate while maintaining USB 3.0 transmission speed requirements.

AI summary
A plug connector has an insulative housing, a mounting bracket, multiple first terminals, multiple second terminals and a shell. The mounting bracket is mounted on the insulative housing. The first terminals are mounted through the insulative housing and have soldering sections arranged in a first transverse row. The second terminals are mounted through the mounting bracket and have soldering sections arranged in a second transverse row. The soldering sections arranged in the different rows reduce a density of a soldering section layout and facilitate soldering the plug connector to a PCB.
