Electromagnetic Relay Details TRIZ Cases

An asymmetric L-shaped armature and yoke simplify bistable relay assembly, cutting parts and cost while preserving stable magnetic latching.

A yoke aligned with current-generated magnetic flux steers separation arcs away from relay contacts, improving switching reliability and contact life.

Multiple unshelled relay cores are potted in one housing cavity to cut relay size, improve space use, and limit heat and arc impact.

A yoke placed beside relay contacts concentrates magnetic flux to drive switching arcs away and limit contact deterioration under high current.

A non-crossed terminal layout in a multi-phase relay cuts copper use, simplifies spot-welding, and improves insulation safety.

Blocking walls and separated terminal layout keep arc debris away from auxiliary contacts while insulating strong and weak currents.

Plug-in terminals and lug plates replace manual coil wiring in a contactor electromagnetic assembly, improving connection stability and easing assembly.

Partitioned arc spaces and magnetic deflection help high-voltage contactors extinguish arcs, protect chamber walls, and switch bidirectionally.

Plastic U-shaped walls shield the auxiliary contact from arc debris and deformation while maintaining strong-weak voltage insulation.

A shared drive coil and magnetic movement assembly shrinks leakage interrupter core units while preserving reliable trip and reset action.

A webbed switching chamber base traps melting beads while ventilation channels speed gas exchange and support faster arc extinction.

A movable wall linked to the plunger blocks foreign particles from the contact region without adding the resistance that slows relay switching.

An insulating member and base wall raise relay insulation distance between coil, yoke, and terminals without adding size or extra parts.

An insulating member and base wall extend relay insulation paths between coil, yoke, and terminals without adding size or parts.

Single-path breaker modules cut replacement cost and save space while arc guiding and extinguishing parts shorten arc dead time.

Induced magnetic latching holds contactor contacts closed against Lorentz forces, preventing short-circuit arcing without a larger coil.

Induced magnetic latching holds contactor contacts closed under short-circuit Lorentz forces, preventing arcing damage without a larger coil.

A spring locked part uses its own resilience to secure small relay terminals, avoiding temporary bonding while maintaining press-fit strength.

Controlled rupture disks relieve arc-driven pressure in hermetic switch housings, preventing uncontrolled breaches and improving reliability.

A dual magnetic conductive loop boosts contact holding force under short-circuit current while supporting arc extinction in a DC relay.

A three-magnet arc field and magnetic conductive loops help a DC relay resist contact repulsion and suppress arcing during short circuits.

A magnetic reinforcing member boosts relay flux and movable-core attraction while enabling more flexible arc quenching directions.

A shaft-mounted stopper keeps the movable iron core and drive shaft moving together after fixation damage, preserving relay contact function.

A holding unit brakes the bridge element in an intermediate position to prevent acceleration-driven closure and high-voltage short circuits.

A single fastener links lower frame, upper frame, and arc cover to prevent arc box separation during fault currents and repeated arc extinguishing.

A clearance-coupled movable contact piece tilts to keep terminal contact after contact loss, reducing interference and spring force demand.

Distributed vents across the arc shield, shaft assembly, and core speed evacuation, reduce residual gas, and keep DC contact resistance low.
