Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional shielding structure with metal shields and grounding terminals is used, then the connector provides basic electromagnetic shielding, but the shielding effectiveness is insufficient to meet increasing signal integrity requirements
Solution Approach 1:
The patent implements a nested shielding structure where the metal shield surrounding member is positioned within the shielding cavity formed by the first metal shield, second metal shield, and grounding terminals. This nested arrangement creates multiple layers of electromagnetic shielding, with each layer contributing to the overall shielding effectiveness and signal integrity protection.
Solution Approach 2:
The patent extends the shielding structure by adding the metal shield surrounding member that protrudes into the receiving space of the connector housing. This dimensional extension creates an additional shielding zone that enhances electromagnetic interference protection without compromising the existing shielding cavity structure.
2Object-affected harmful factors
If the shielding structure is extended to improve shielding effectiveness, then electromagnetic interference protection is enhanced, but the connector structure becomes more complex
Solution Approach 1:
The metal shield surrounding member serves multiple functions: it extends the shielding effect into the receiving space, provides structural support within the connector assembly, and maintains positional alignment of the mating modules. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in structural complexity.
Solution Approach 2:
The patent integrates the metal shield surrounding member with the existing shielding cavity structure and connector housing. By merging these elements into a coordinated assembly where the surrounding member protrudes into the receiving space, the design achieves enhanced shielding without requiring entirely separate shielding components, thus controlling structural complexity.

AI summary
A second electrical connector includes a second housing and a second mating module mounted to the second housing. The second mating module includes a number of second cable modules and a second fixing block fixed on the second cable modules. Each second cable module includes a second terminal module, a second cable, a second shielding clamping plate clamping the second cable, and a metal shield surrounding member at least partially sleeved on the second terminal module. The second shielding clamping plate is in contact with the metal shield surrounding member, thereby increasing the ground shielding area and improving the shielding effect. A connector assembly having the second electrical connector is also disclosed.
