Abstract
A magnetic flux assembly for closing a magnetic circuit of a relay and a relay. The magnetic flux assembly has a yoke and a U-shaped armature that is movable relative to the yoke. The yoke has a coil part that is in a coil and a flux conduction part that conducts the magnetic flux generated by the coil.
Claims18
A magnetic flux assembly for closing a magnetic circuit of a relay comprising:
- a U-shaped yoke having:
- (a) a first leg defining a coil part in a coil,
- (b) a flux conduction part that conducts magnetic flux generated by the coil and including a second leg and a central leg extending between the first leg and the second leg, and
- (c) a protrusion extending from the central leg;
- and
- a U-shaped armature movable relative to the yoke, the protrusion protruding in a direction of the armature for conducting magnetic flux towards the armature.

A relay comprising:
- a coil;
- and
- a magnetic flux assembly comprising:
- (a) a yoke having:
- (1) a coil part in the coil,
- (2) a flux conduction part that conducts magnetic flux generated by the coil, and
- (3) a protrusion;
- and
- (b) a U-shaped armature having:
- (1) a proximal leg pivotally connected to the yoke,
- (2) a central leg defining a magnetic attraction face, and
- (3) a distal leg, wherein the protrusion protrudes toward the distal leg,
- wherein the armature is movable relative to the yoke, in the open position a distance between the distal leg of the armature and the yoke is smaller than a distance between the central leg of the armature and the yoke, the protrusion protruding in a direction of the armature for conducting magnetic flux towards the armature.

A magnetic flux assembly for closing a magnetic circuit of a relay comprising:
- a yoke having a coil part in a coil and a flux conduction part that conducts magnetic flux generated by the coil;
- and
- a U-shaped armature including a proximal leg, a central leg, and a distal leg, the armature movable relative to the yoke between an open position and a closed position in an actuation direction, a first magnetic attraction face defined on the central leg of the armature is closer to a second magnetic attraction face of the yoke in the closed position than in the open position, the armature overlaps the yoke in a direction perpendicular to the actuation direction in the open position, the coil part of the yoke arranged generally parallel to the flux conduction part having the second magnetic attraction face.
