Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors face limitations in design configuration, making it difficult to further improve their structure for high-speed signal transmission.
Innovation Solution
The electrical connector features a housing with an insulating outer case and a conductive inner case, along with transmission wafers that include signal and ground terminals, and a shielding sheet with outer fixing arms, arranged in a new configuration where the ground and signal contacting segments are in one row and the outer fixing arms are in another row, allowing for improved space and design expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electrical connector structure is used, then manufacturing and assembly are straightforward, but design configuration is limited and further improvement is difficult
Solution Approach 1:
The transmission wafer is divided into distinct functional segments: signal terminals with embedded and contacting segments, ground terminals with similar segmentation, and a shielding sheet with outer fixing arms. This segmentation allows each component to be optimized independently while maintaining overall connector functionality, thereby improving design configuration without excessive complexity
Solution Approach 2:
The patent arranges signal contacting segments and ground contacting segments in one row along the second direction, while outer fixing arms are arranged in another row. This multi-row arrangement in different dimensions optimizes space utilization and improves design flexibility without significantly increasing structural complexity
2Area of stationary object
If signal and ground terminals are arranged in separate rows, then assembly is simpler, but space utilization and signal performance are suboptimal
Solution Approach 1:
Signal contacting segments and ground contacting segments are arranged in the same row along the second direction, merging what were traditionally separate rows. This improves space utilization and enhances signal transmission performance by optimizing the geometric arrangement, while the modular wafer design keeps assembly straightforward
3Reliability
If outer fixing arms are integrated into the shielding sheet body, then structure is simpler, but fixing reliability and electrical coupling are insufficient
Solution Approach 1:
The shielding sheet is segmented into a sheet body and multiple outer fixing arms that extend from it. Each fixing arm can be independently positioned and fixed to the conductive inner case, providing reliable mechanical attachment and electrical coupling without significantly complicating the overall shielding sheet structure
Solution Approach 2:
The outer fixing arms act as intermediary elements between the shielding sheet body and the conductive inner case. They provide both mechanical fixing and electrical coupling functions, enhancing reliability while keeping the shielding sheet structure relatively simple through this intermediate component

AI summary
An electrical connector and a transmission wafer thereof are provided. The transmission wafer includes an insulating frame, a plurality of signal terminals and ground terminals fixed on the insulating frame, and a shielding sheet that is assembled to the insulating frame. Each of the signal terminals includes a signal contacting segment protruding from the insulating frame. Each of the ground terminals includes a ground contacting segment having a ground contact and protruding from the insulating frame. The shielding sheet includes a sheet body and a plurality of outer fixing arms extending from the sheet body. Each of the outer fixing arms corresponds in position to one of the ground contacting segments along a first direction. A free end portion of each of the outer fixing arms protrudes from the ground contact of the corresponding ground contacting segment along an insertion direction that is perpendicular to the first direction.
