Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the connector includes a large number of terminals with small intervals, then the terminal density is improved, but the signal transmission quality deteriorates due to interference
Solution Approach 1:
The connector is divided into multiple independent terminal modules, each with its own shielding structure. The shielding plate is segmented to provide individual shielding for each terminal group, reducing electromagnetic interference between adjacent terminals while maintaining high terminal density.
Solution Approach 2:
A shielding plate is introduced as an intermediary element between terminal groups to block electromagnetic interference. The shielding plate acts as a mediator that prevents signal interference while allowing the terminals to maintain small intervals for high density connectivity.
2Ease of operation
If the connector allows flexible insertion, then the ease of operation is improved, but the risk of wrong angle insertion and terminal damage increases
Solution Approach 1:
The connector employs asymmetric positioning structures including positioning plates with positioning holes and corresponding positioning protrusions on the mating connector. These asymmetric features guide the insertion angle and prevent wrong-angle mating, ensuring reliable connection while maintaining ease of operation.
Solution Approach 2:
Positioning structures such as positioning plates and positioning holes are provided in advance to guide the insertion process. The positioning features preliminarily align the connectors before full insertion, preventing wrong-angle insertion and terminal damage while maintaining user-friendly operation.
3Reliability
If shielding structures are added to improve signal quality, then the signal transmission quality is improved, but the device complexity increases
Solution Approach 1:
The shielding plate is merged with the metal shell structure, integrating the shielding function into the existing connector housing. This combination reduces the need for separate shielding components and simplifies the overall structure while maintaining effective electromagnetic shielding for high-quality signal transmission.

AI summary
A connector includes a metal shell and a terminal module coupled to the metal shell. The metal shell includes a main body, a shielding plate protruding from the main body, and a positioning plate further protruding from the shielding plate. The terminal module includes a first terminal module and a second terminal module disposed on opposite sides of the shielding plate, respectively. By providing the first terminal module and the second terminal module on the opposite sides of the shielding plate, the signal shielding of the first terminal module and the second terminal module can be improved. A connector assembly having the connector is also disclosed.
