Two Pole Connections TRIZ Cases

A tubular insulation member and core connector terminal preserve conductor-to-dielectric ratio and shielding continuity during automotive coaxial cable repair.

Radial ground-tab arms bridge PCB-to-connector gaps, improving high-frequency RF transition while avoiding manual solder touch-up.

Pressed receiving portions and a crimped contact eliminate gaps on the cable outer conductor to stabilize electromagnetic shielding.

Distributed plug-in battery units coordinate charging and discharge from pricing signals to shift energy use and lower utility bills.

Periodic voltage and current sensing lets a smart plug detect appliance faults from power patterns and remotely switch power when needed.

A removable surge protector cartridge lets the plug keep delivering power after a surge while restoring protection without replacing the whole strip.

Sloped protrusions on the contact pin increase housing locking force, prevent pin shift or removal, and preserve high-frequency signal stability.

Funnel-guided contacts and aligned welding openings improve high-speed connector alignment, impedance matching, and mechanical integrity.

An axial contact sleeve layout improves shielding and signal quality above 5 GHz while reducing abrasion from connector tolerances and mating cycles.

Optical sensing and processor-controlled switching isolate only the faulty outlet while improving arc, ground, surge, and overcurrent protection.

A movable inner contact lets the board coaxial connector float under vibration, reducing damage from repeated use while keeping signal transmission stable.

Folded linked plate springs give the contact portion larger insertion-direction travel, helping connectors keep stable conductivity despite dimensional variation.

A conductive spacer and tubular insulation preserve conductor-to-dielectric ratio, prevent air pockets, and maintain coaxial signal integrity.

A spring-biased pin and shielded interposer enable RF and data coupling between closely spaced PCBs while tolerating board angle variation.

Separate conductive lid and pin pathways let closely spaced PCBs carry data and RF signals in a compact contactor that tolerates misalignment.

A sealed cavity filled with thermally conductive liquid spreads PCB heat quickly, enabling smaller high-power adapters without local overheating.

A PCB replaces internal metal bars to simplify connector distributor assembly, shrink the housing, and enable modular current control.

Elastic nested terminals absorb cavity filter assembly tolerance, maintain pad contact, and prevent RF signal disconnection in compact antenna filters.

A shared housing combines optical and electrical ports in one connector, cutting interface count, device volume, and plugging steps.
