USB 3.0 Socket Connector Single Row SMT Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB 3.0 socket connectors are large and prone to crosstalk due to their complex structure and two-row terminal arrangement, which reduces their compactness and PCB utilization rate, especially when using surface mount technology (SMT) soldering processes.
Innovation Solution
A high-frequency SMT type socket connector with first and second terminals arranged in a single transverse row, featuring L-shaped SMT soldering sections to prevent crosstalk, allowing for compact design and improved PCB utilization, while adhering to USB 3.0 protocol standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional USB 3.0 socket connectors use two rows of terminals to implement USB 2.0 or 3.0 protocol alternatively, then the connector can support both protocols, but the connector size becomes large and structure becomes complicated, increasing molding design cost and manufacturing cost
Solution Approach 1:
The patent merges USB 2.0 and USB 3.0 terminal functions into a single row arrangement. The insulating housing contains integrated terminal structures where grounding terminals, power terminals, and signal terminals are arranged in one row, eliminating the need for separate two-row configurations for different protocols.
Solution Approach 2:
The connector design provides universal support for both USB 2.0 and USB 3.0 protocols through a unified single-row terminal structure. The same physical connector can accommodate both protocol standards without requiring separate connector designs, achieving multi-functionality in a compact form.
2Reliability
If conventional USB 3.0 socket connectors use two rows of terminals, then the connector can implement USB 3.0 protocol, but crosstalk between high frequency signal transmission terminals occurs, causing high frequency data transmission failure
Solution Approach 1:
The patent applies local quality by assigning specific functional characteristics to different terminal positions within the single row. Grounding terminals are strategically placed at specific positions (e.g., first and last positions) to provide electromagnetic shielding and reduce crosstalk between adjacent signal terminals, creating localized protective zones throughout the terminal row.
Solution Approach 2:
The patent transitions from a two-dimensional two-row terminal arrangement to a one-dimensional single-row arrangement. This dimensional change reorganizes terminal spacing and relationships, allowing for optimized signal integrity through controlled distances between terminals and strategic placement of grounding elements within the single row configuration.
3Ease of manufacture
If conventional USB 3.0 socket connectors use two rows of soldering sections, then the connector can be mounted on PCB, but the soldering sections occupy more surface areas of PCB, decreasing the utilization rate of PCB
Solution Approach 1:
The patent merges the soldering sections into a single row configuration that matches the single row terminal arrangement. The insulating housing integrates mounting structures with the terminal rows, allowing all soldering connections to be made in one linear sequence rather than requiring two separate rows, thereby reducing the total PCB surface area occupied.

AI summary
A high frequency socket connector has an insulating housing, a mounting bracket, multiple first terminals, multiple second terminals and a shell. The first and second terminals are mounted in the insulating housing, are capable of implementing USB 3.0 protocol. The shell covers the insulating housing and terminals. Each of the terminals has a SMT soldering section adapted to SMT soldering processes. All the SMT soldering sections are arranged in a transverse row to make the socket connector compact.
