  • Patent number: 9852869
    Abstract: A switch module with a built-in structure of anti-surge and dual disconnection mainly comprises an overcurrent protection switch having plates and insulating elements for anti-surge and dual disconnection structure ingeniously built inside a heat-resisting housing. The switch module has a first connecting point and a second connecting point for operation. When overvoltage occurs, temperature of at least one metal oxide varistor would instantly rise up to a degree higher than the melting point thereof, melting at least one thermo-sensitive piece, loosening at least one spring element, displacing a pushing element and thus forcing the connecting points detaching from each other to turn off the switch and stop supplying electricity power; meanwhile, insulating elements would isolate conductive components such as thermo-sensitive pieces, spring elements and plates to further ensure a complete disconnection and more of electricity safety.

  • Patent number: 9791901
    Abstract: A dual redundant computer safety relay box system includes first and second fail-safe computing systems (FSCs) individually mounted to first and second printed circuit boards. Each FSC includes two computing modules (CPUs) designated as a first CPU and a second CPU. The first and second FSC's are both connected to a safety relay box. The printed circuit boards are isolable from each other permitting maintenance on one of the printed circuit boards while operation of the FSC of the other printed circuit board is maintained. In each FSC a health signal generated from the first and second printed circuit boards of the first and second CPUs defines a multi-level dynamic pulse signal. Presence of the dynamic pulse signal produces an output identified as each of a first and a second healthy indication signal from each of the CPUs of one of the first or second FSCs.

  • Patent number: 9711307
    Abstract: In an overload relay, a tripping actuator 12 has a first magnet 18 and a moveable contact carrier 20 has a second magnet 28 mounted opposed to the first magnet. A moveable contact 22 on the moveable contact carrier is urged by repulsion between the magnets, to make a normally closed connection with a stationary contact 24, when the tripping actuator is in an ON position 15 and the contact carrier in a first stable position 26?. The magnets pass through an over-center tripping position (T) when the tripping actuator is moved to an OFF position 23 in response to an overcurrent condition sensed by a bimetallic thermal overload sensor 16. The magnets repel each other after passing through the over-center tripping position, to thereby urge the moveable contact into a second stable position 26, away from the stationary contact, to break the normally closed connection with the stationary contact.
