Engineering Contradiction Analysis
1Volume of moving object
If terminals are arranged more densely to reduce connector volume, then the connector size is reduced, but signal interference between terminals increases
Solution Approach 1:
The isolation plate is divided into multiple grounding arms (first grounding arm, second grounding arm, third grounding arm, fourth grounding arm) that extend in different directions. Each grounding arm segments the isolation function to different spatial zones, providing comprehensive shielding against signal interference while maintaining compact connector dimensions.
Solution Approach 2:
The grounding arms extend in multiple dimensions (length, width, and height directions) rather than a single plane. The first and second grounding arms extend in the length direction, while the third and fourth grounding arms extend in the width direction, creating three-dimensional shielding coverage that effectively blocks signal interference from multiple angles.
2Device complexity
If a simple metal isolation plate is used, then the device structure is simple, but the shielding function is insufficient for high-frequency signals
Solution Approach 1:
The isolation plate is segmented into multiple functional grounding arms instead of a single solid plate. This segmentation allows each arm to independently provide shielding in specific directions, enhancing the overall shielding function for high-frequency signals while keeping the total material usage and structural complexity relatively low.
Solution Approach 2:
Different grounding arms are positioned to provide localized shielding quality where needed. The first and second grounding arms provide shielding along the length direction, while the third and fourth grounding arms provide shielding along the width direction, creating non-uniform but optimized shielding distribution that matches the interference patterns of high-frequency signals.

AI summary
Provided is an electrical connector. The electrical connector includes an insulation body, a terminal group and an isolation plate, where the terminal group and the isolation plate are received in the insulation body. The terminal group includes upper-row terminals and lower-row terminals. The isolation plate is between the upper-row terminals and the lower-row terminals. The isolation plate has a pair of upper grounding arms and a pair of lower grounding arms which are integrally connected with the isolation plate. The pair of upper grounding arms is in a same plane as the upper-row terminals and is on two sides of the upper-row terminals respectively. The pair of lower grounding arms is in a same plane as the lower-row terminals and is on two sides of the lower-row terminals respectively.
