Multipole Connector Terminal Arrangement for High-Frequency Noise Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multipole connector sets fail to sufficiently suppress noise intrusion and radiation, especially with increasing signal frequencies, due to limitations in shielding structures.
Innovation Solution
A multipole connector set design where first and second connectors are mated, with signal and ground terminals arranged in specific configurations to form assemblies, utilizing connection portions that enhance shielding performance by positioning them in a way that minimizes electromagnetic interference and radiation, and includes center shielding members for improved isolation.

1Object-affected harmful factors
If shielding structures are used to suppress noise intrusion and radiation, then noise suppression performance is improved, but the shielding effect becomes insufficient at increasingly higher signal frequencies
Solution Approach 1:
The connector terminals are divided into signal terminals and ground terminals, with ground terminals positioned at both ends of signal terminals in the width direction. This segmentation creates multiple ground shielding points that effectively block high-frequency electromagnetic noise, resolving the insufficiency of traditional shielding structures at high frequencies.
Solution Approach 2:
Ground terminals are strategically positioned at specific locations (both ends of signal terminals in the width direction) rather than uniformly distributed. This local quality approach creates optimal electromagnetic shielding zones exactly where needed for high-frequency signal protection, enhancing shielding effectiveness without adding overall complexity.
2Object-affected harmful factors
If multiple ground terminals are used to improve shielding, then noise suppression is enhanced, but the complexity of terminal arrangement increases
Solution Approach 1:
The terminal arrangement uses asymmetric positioning where ground terminals are placed at both ends of signal terminals in the width direction, creating an uneven but optimized pattern. This asymmetric design achieves superior electromagnetic shielding compared to symmetric arrangements while maintaining clear, manageable configuration rules that reduce overall system complexity.
Solution Approach 2:
The terminal arrangement extends protection into the width direction by positioning ground terminals at both ends of signal terminals, adding a dimensional aspect to shielding that was previously limited to length-direction arrangements. This dimensional expansion provides comprehensive high-frequency noise suppression without complicating the basic terminal structure.

AI summary
When a multipole connector set is viewed from a height direction and when a first ground terminal assembly, a first signal terminal assembly, and a second ground terminal assembly are arranged in a length direction as follows: A connection portion at the outermost side in a width direction of the first ground terminal assembly is a first connection portion, a connection portion at the outermost side in the width direction of the second ground terminal assembly is a second connection portion, a connection portion arranged at the innermost side in the width direction of the first ground terminal assembly is a third connection portion, and a connection portion at the innermost side in the width direction of the second ground terminal assembly is a fourth connection portion. All connection portions of the first signal terminal assemblies are inside a quadrangle connecting the first, second, third and fourth connection portions.
