Coupling Protective Earth/Shielding Arrangements TRIZ Cases

Facing ground terminals and a mating shield member reduce same-row and inter-row crosstalk in high-frequency connector layouts.

Movable ground walls and intermediary ground contacts shield closely spaced RF contacts, cutting interference while saving PCB area.

An elastic grounding plate replaces screw-fastened PE contacts, enabling denser connector inserts with faster assembly and easy connection changes.

Ground contacts and a ground housing isolate RF and transmission contacts to cut interference, improve EMI shielding, and save PCB space.

A grounded conductive shell and lossy member suppress connector radiation and crosstalk, helping 32 Gbps interfaces meet signal integrity limits.

A shielding plate and asymmetric positioning features improve high-density signal integrity while preventing wrong-angle connector damage.

Using two identical L-shaped shield elements, this case achieves all-around PCB connector EMC shielding with lower part count and assembly cost.

A grounded braided shield in a hybrid DC bus cable splits common mode currents, cutting EMI and reducing MOV stress in distributed motor drives.

A coupled multi-row ground structure forms a shield box in the connector to suppress resonance and crosstalk in differential pairs.

Ground shields and beams between contact pairs cut cross-talk and return loss in card edge connectors for more reliable high-speed transmission.

A spring-loaded contact path presses terminal connections toward the shield shell, shortening thermal resistance and avoiding resin-related heat variation.
