Engineering Contradiction Analysis
1Shape
If ground shield plates are formed by cutting and signal terminals are formed by bending, then the required shapes are achieved, but the manufacturing process becomes significantly more complex
Solution Approach 1:
The patent merges the ground shield plate and signal terminal into a single integrated terminal structure formed by one stamping operation. The terminal includes both the signal contact portion and the ground shield portions as integral parts, eliminating the need for separate cutting and bending processes that were previously required to create these components with different shapes.
Solution Approach 2:
The patent changes the manufacturing parameter from multiple processes (cutting + bending) to a single stamping process. By using a stamping die with appropriate cavities and protrusions, the terminal is formed directly in the desired shape without requiring subsequent bending operations, thus simplifying manufacturing while achieving the required geometric configurations.
2Shape
If different forming methods are used for ground shield plates and signal terminals, then the required structures are achieved, but the production efficiency decreases
Solution Approach 1:
The patent combines multiple terminal components into a single stamped piece. The terminal includes the signal contact portion, ground contact portions, and ground shield portions all formed as one integrated component through a single stamping operation, thereby eliminating multiple manufacturing steps and improving production efficiency.
Solution Approach 2:
The stamped terminal structure serves multiple functions simultaneously: it provides signal transmission through the signal contact portion, electrical grounding through the ground contact portions, and electromagnetic shielding through the ground shield portions. This multi-functional integration in a single component accelerates production by eliminating the need to manufacture and assemble separate components.

AI summary
An electrical connector includes an insulating housing and plural terminal rows. The insulating housing has an upper face, a lower face, and a terminal slot. Each of the terminals of the plural terminal rows is formed by stamping a metal plate and includes a base portion fixed in the terminal slot, an upper resilient arm, and a lower resilient arm. The base portion includes two metal faces opposite each other, a left cut face and a right cut face opposite each other, and an upper cut face and a lower cut face opposite each other. The upper resilient arm sequentially includes an upper portion extending upward from the upper cut face, a horizontal portion, and an upper abutting portion extending downward from an end of the horizontal portion. Each of the terminals of the plural terminal rows further includes an upper contact portion protruding upward from the horizontal portion.
