High-Speed Plug Connector Single-Row Terminal Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
USB 3.0 connectors are structurally complex, leading to increased size, higher manufacturing costs, and crosstalk issues due to two rows of terminals, which occupy more PCB surface area and hinder high-speed signal transmission.
Innovation Solution
A high-speed plug connector with soldering sections arranged in a transverse row, using separate insulating housing and mounting bracket components, reduces PCB surface area requirements and minimizes crosstalk by alternating signal and non-signal transmission terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If two rows of terminals are used to achieve USB 3.0 high-speed transmission, then transmission speed is improved, but device complexity and PCB surface area increase
Solution Approach 1:
The patent transitions from a conventional two-row terminal arrangement to a single-row configuration by utilizing a mounting bracket that extends in the longitudinal direction. This dimensional reorganization allows all terminals to be arranged in one row along the length of the connector rather than requiring two rows across the width, thereby reducing PCB surface area while maintaining USB 3.0 transmission capabilities
Solution Approach 2:
The connector is divided into functional segments: first terminals mounted on the insulating housing, second terminals mounted on the mounting bracket, and a shell covering the assembly. This segmentation allows the terminals to be distributed along the longitudinal axis rather than requiring a compact two-row arrangement, reducing overall complexity while enabling high-speed transmission
2Speed
If two rows of terminals are used for USB 3.0 connection, then transmission capability is improved, but manufacturing cost increases
Solution Approach 1:
By arranging terminals in a single row along the longitudinal direction rather than two rows, the connector achieves a more compact footprint that simplifies PCB layout and assembly processes. This dimensional change reduces manufacturing complexity and associated costs while maintaining USB 3.0 performance
Solution Approach 2:
The mounting bracket serves multiple functions: it holds the second terminals, provides structural support, and enables the single-row configuration. This multi-functionality reduces the need for additional components, simplifying manufacturing and reducing costs
3Adaptability or versatility
If two rows of terminals are used, then connection capacity is improved, but crosstalk between terminals occurs
Solution Approach 1:
The single-row longitudinal arrangement increases the spacing between adjacent terminals compared to a compact two-row configuration. This spatial separation reduces electromagnetic coupling and crosstalk between terminals while maintaining the full USB 3.0 connection capacity through the distributed terminal arrangement along the length of the connector
4Adaptability or versatility
If two rows of soldering sections are used, then terminal capacity is improved, but PCB surface area increases
Solution Approach 1:
The soldering sections are arranged in a single row along the longitudinal direction of the connector, utilizing the length dimension rather than requiring width for a second row. This dimensional reorganization reduces the PCB surface area occupied by the connector while maintaining full terminal capacity for USB 3.0 connections

AI summary
A high-speed plug connector has an insulating housing, a mounting bracket, multiple first terminals, multiple second terminals and a shell. The first terminals are mounted on the insulating housing. The second terminals are mounted on the mounting bracket. Each terminal has a mounting section, a soldering section and a contacting section. The soldering sections are arranged in a transverse row instead of two rows to make the high-speed plug connector compact and reduce mounting surface areas of a PCB on which the soldering sections is soldered.
