Abstract
An electromagnetic breaker includes a housing (10) having two conductors (30, 31), and a slidable conductor (40) slidably disposed in the housing (10) and movable to engage with the conductors (30, 31) and to electrically couple the conductors (30, 31) together. An electromagnetic device (2) may selectively force the slidable conductor (40) toward and away from the conductors (30, 31). The slidable conductor (40) includes a magnetic member (44), the electromagnetic device (2) includes a core for acting with the magnetic member (44). A spring device (14) may bias the conductors (30, 31) toward the slidable conductor (40). Another spring device (47) may bias the slidable conductor (40) away from the conductors (30, 31).
Claims6
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).
