Serial Bus Connector With Nested Conductive Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing USB connectors, such as Micro USB, face structural weakness due to the high density of terminals in a limited space, leading to a limited lifespan of less than ten thousand plug and unplug cycles, which is inadequate for modern electronic devices requiring faster data transmission speeds like USB 3.1 Type-C.
Innovation Solution
A serial bus connector design featuring an insulated body with conductive covers and a base assembly that includes spring contact sections, retaining sections, and connecting sections, along with an outer shielding, arranged to provide a robust and compact structure that accommodates multiple terminals and ensures secure electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a large number of terminals are accommodated in a limited space to achieve USB 3.1 Type-C specifications, then the transmission speed increases to 10 Gbit/s, but the whole structure becomes weak and fails to achieve more than ten thousand plug and unplug cycles
Solution Approach 1:
The connector is divided into multiple functional modules: an insulated body containing terminal passages, a base assembly with terminal seats, conductive covers with conductive portions, and an outer shielding. This segmentation allows each module to be optimized independently for both high-speed transmission and durability, resolving the contradiction between accommodating multiple terminals and maintaining structural strength.
Solution Approach 2:
The connector employs composite material construction with the insulated body made of insulating material, conductive portions made of conductive material, and spring contact sections made of elastic material. This combination of materials provides both the electrical performance needed for 10 Gbit/s transmission and the mechanical strength required for over ten thousand plug and unplug cycles.
2Volume of moving object
If the size of the connector is reduced to be close to Micro USB while achieving USB 3.1 Type-C functionality, then the connector becomes more compact, but the structure becomes weaker
Solution Approach 1:
The design implements a nested structure where the base assembly is received within the insulated body, conductive covers are positioned within the terminal passages, and spring contact sections are nested within the terminal seats. This nesting allows maximum utilization of the compact USB 3.1 Type-C form factor while maintaining structural integrity through hierarchical support.
Solution Approach 2:
The connector utilizes three-dimensional spatial arrangement by positioning terminal passages, conductive covers, and base assembly components in different spatial dimensions and orientations. This dimensional optimization allows the compact connector to accommodate all necessary terminals and structural elements without compromising strength, achieving both small size and durability.

AI summary
A serial bus connector is provided comprising as least one insulated body having a plurality of openings, a plurality of rows of terminals, a base assembly, at least one conductive cover, and an outer shielding. The at least one conductive cover is located upon an outer surface of a side wall of the insulated body, and comprises a plurality of first conductive portions and second conductive portions. The first conductive portions are formed by bending the conductive cover toward a direction of the inside of the insulated body, and the second conductive portions are formed by bending the conductive cover toward an opposite direction of the insulated body. The first conductive portions pass through the openings of the insulated body to extend into the inside of the insulated body for electrically connecting with another complementary connector.
