Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If contacts and shielding plates are manufactured and assembled separately in the socket body, then the shielding effect is improved, but the manufacturing process becomes complex and manufacturing cost increases
Solution Approach 1:
The patent combines the shielding plate and terminal into a single integrated component manufactured as one piece. The shielding plate includes integrated terminals that extend from its surface, eliminating the need for separate assembly steps. This merging maintains the shielding effect while significantly simplifying the manufacturing process and reducing costs.
Solution Approach 2:
The shielding plate is designed to serve multiple functions simultaneously: it provides electromagnetic shielding, structural support, and electrical connection through its integrated terminals. This multi-functionality reduces the number of separate components needed and simplifies the overall manufacturing process while maintaining effective shielding.
2Object-affected harmful factors
If contacts and shielding plates are manufactured and assembled separately in the socket body, then the shielding effect is improved, but the manufacturing cost increases
Solution Approach 1:
The shielding plate and terminal are merged into a single integrated component manufactured in one process. This eliminates the need for separate procurement, manufacturing, and assembly operations, thereby reducing manufacturing costs while maintaining the shielding effect.
Solution Approach 2:
The design eliminates the need for separate assembly operations and associated labor costs. By integrating the terminal into the shielding plate, the patent discards the complex multi-step assembly process and recovers value through simplified manufacturing and reduced labor requirements.
3Volume of moving object
If the density of the pads of the CPU and the density of the pads of the printed circuit board become larger, then the size of the electrical connector becomes smaller, but the electromagnetic interference between adjacent contacts becomes serious
Solution Approach 1:
The shielding plate is positioned locally between adjacent contacts to provide targeted electromagnetic shielding in the specific areas where interference occurs. This localized shielding approach effectively reduces electromagnetic interference between dense contacts without requiring increased overall connector size.
Solution Approach 2:
The shielding plate acts as an intermediary element positioned between adjacent contacts to block electromagnetic interference. This mediator structure allows the connector to maintain small size with high pad density while preventing harmful electromagnetic coupling between neighboring contacts.

AI summary
An electrical connector electrically for connecting a chip module having a contacting surface to a printed circuit board includes an insulative housing, a number of terminals received therein and a number of shielding plates received in the insulative housing and located around the terminals. The insulative housing is insert molded with the shielding plates and the terminals and includes a plurality of through slots. The terminals are formed by separated from the shielding plates by the through slot.
