Patent ID: 7138894

Claim:
An electromagnetic breaker comprising a housing ( 10 ) including a casing ( 11 ) formed in the housing ( 10 ) which receives an electromagnetic device ( 2 ) which includes a core ( 20 ) and a coil ( 21 ) engaged around the core ( 20 ); the electromagnetic device ( 2 ) including a control device ( 23 ) disposed in the housing ( 10 ), and a processor device ( 24 ) for controlling the operation of the core ( 20 ) and the coil ( 21 ) of the electromagnetic device ( 2 ) via the control device ( 23 ); the housing ( 10 ) including at least one partition ( 12 ) formed in the housing ( 10 ), and at least one first springs ( 14 ) being received in the partitions ( 12 ) of the housing ( 10 ); the housing ( 10 ) including at least one stop ( 13 ) extended into the housing ( 10 ) and including a compartment ( 15 ) formed therein; two first conductors ( 30 , 31 ) are slidably received in the housing ( 10 ) and each including a first terminal ( 32 , 33 ), respectively provided on top and located close to the stops ( 13 ) of the housing 10 respectively; the first spring ( 14 ) being engaged with the first conductors ( 30 , 31 ) to bias the first terminals ( 32 , 33 ) upwardly relative to the housing 10 ; a rod ( 40 ) slidably received in the compartment ( 15 ) of the housing ( 10 ), and includes a second conductor ( 41 ) attached to the bottom and having two second terminals ( 42 , 43 ) for being moved to selectively engage or contact with the first terminals ( 32 , 33 ) of first conductors ( 30 , 31 ), and thus to electrically couple the first terminals ( 32 , 33 ) of first conductors ( 30 , 31 ) together; the rod ( 40 ) further including a magnetic member ( 44 ) attached to the second conductor ( 41 ), for being acted with the core ( 20 ) of the electromagnetic device ( 2 ), and including a head ( 45 ) provided on top for engaging with a spring ( 47 ) which may bias the terminals ( 42 , 43 ) of the conductor ( 41 ) away from the terminals ( 32 , 33 ) of conductors ( 30 , 31 ).
