Electromagnetic Relay Details TRIZ Cases
- Relay Spool Flange Structure for Core-Terminal Insulation
A stepped spool flange increases insulation between the iron core and fixed terminal without making the electromagnetic relay larger.
- Electromagnetic Relay Spool Wall for Terminal Insulation
A spool lateral wall extends the creepage path between fixed terminals, preserving relay insulation despite wear particles without enlarging the housing.
- Electromagnetic Relay Spool Layout for Compact Terminal Insulation
A spool with vertical and lateral wall portions lets the coil terminal stay compact while preserving insulation distance from the contact terminal.
- DC Relay Magnetic Loop Layout for Short-Circuit Contact Stability
Two magnetic conductive loops boost contact suction in a DC relay, preventing bounce-off and arcing under high short-circuit currents.
- High-Voltage Switch Layout Without Arc Suppression Elements
By removing arc suppression elements and solenoids, this switch keeps 500V breakdown capability with a simpler rotary contact layout.
- Electromagnetic Relay Pivot Structure for Stable Contact Switching
An arcuate pivot in the magnetic drive cuts magnetoresistance, stabilizes contact movement, and enables smaller electromagnetic relays.
- PCB Magnetic Relay Layout for Miniaturized Reliable Switching
A PCB-generated magnetic field replaces bulky relay windings to shrink switching hardware and reduce wear and oxidation at contacts.
- Electromagnetic Relay Contact Structure to Reduce Abrasion Powder
Fixing the movable contact piece to the movable member cuts abrasion powder and lowers contact resistance in an electromagnetic relay.
- Electromagnetic Relay Airflow Guide Wall for Arc-Resistant Contacts
A guide wall redirects short-circuit airflow to press the movable contact piece, boosting contact force and reducing arcing when contacts melt.
- Contactor Coil Control Circuit With Redundant Breaking Logic
A dual-controller breaking path turns off the contactor coil even after software failure, improving safe stop reliability and easing maintenance.
- Contactor Motion Mechanism With Pivoted Brackets for Gravity Balance
A pivoted iron-core and contact-bracket mechanism reduces gravity-induced tilting, improves contact stability, and limits chamber contamination.
- DC Relay Coupling Structure Against Electromagnetic Contactor Separation
A pin and support member stabilize the movable contactor by countering electromagnetic repulsion, avoiding separation and extra fasteners.
- Slotted Magnet Enclosure That Blocks Closed-Door Removal
A slotted enclosure and coupling structure stop magnetic switch parts from being detached or defeated when the door is closed.
- Electromagnetic Switch Contact Insulation With Creepage Protrusions
Spaced protrusions on a plastic insulating part extend creepage distance in an electromagnetic switch, improving isolation and reducing shock risk.
- Electromagnetic Relay Thermal Barrier for Insulator Deformation
A heat-resistant member between the mover and insulator blocks Joule heat transfer, preventing deformation and relay malfunction.
- Slow-Release Relay Circuit for Back-EMF-Free Return Timing
A timer-driven discharge path controls relay return time while preventing counter electromotive voltage that can damage switching circuits.
- Multi-Switch Contactor Assembly With Integrated Pre-Charge Relay
A cam-linked contactor coordinates battery pack switching and pre-charge sequencing to prevent short circuits and cut hold-power demand.
- AC Relay Module Comparator Circuit for Low-Hysteresis Switching
A fixed-voltage comparator circuit stabilizes AC relay switching thresholds, reducing mains interference, hysteresis, and unwanted drop-out.
- Electromagnetic Contactor Yoke Structure for Short-Circuit Hold Force
A fixed yoke anchored in the resin skeleton keeps magnetic closing force stable and helps prevent contact separation during short-circuits.
- Insulated Push Rod Contact Structure for Coil-to-Contact Isolation
An insulated sleeve on the push rod separates the high-voltage contact path from the low-voltage coil to improve creepage distance and switching safety.
