Magnetic latch device for a clapper type contactor

ABSTRACT OF THE DISCLOSURE A magnetic latch for a clapper type contactor having an electromechanical system comprising an operating coil, a coil core, a magnet frame, and an armature includes a magnetic latch plate. The magnetic latch plate includes a stop portion having a pair of ears mounted on a pivoted contact arm. The stop portion of the latch abuts against the magnet frame before energization of the coil so that a flux path includes the core, the magnet frame, the magnetic latch, the armature and the air gap between the armature and core of the coil. After the coil is energized and the current begins to build the magnetic latch saturates an additional parallel flux path travels from the core to the magnet frame through the heel air gap of the armature through the armature to the air gap between the armature and core of the coil until the combined force across the heel air gas and the air gap between the magnet frame and armature and the armature and the core, respectively, are greater than the force between the magnet frame and the magnetic latch, then the armature closes against the core. The amount of latch force desired is controlled by adjusting the cross-sectional area of the magnetic latch.

Electromagnetic relay having dual acting armature

APPLICATION OF ELWYN H. OLSON ELECTROMAGNETIC RELAY HAVING DUAL ACTING ARMATURE ABSTRACT An electromagnetic relay having a dual acting armature has a U-shaped armature with two divergent legs. The armature is pivoted on one of the legs with the pivoted leg being arranged adjacent to an electromagnetic field producing structure including an electrically energizable coil. A first movable electrical contact carrying means is arranged to cooperate with a first one of the legs of the armature to produce a motion of a first electrical contact between a first and a second position in response to an energized and a non-energized state of the coil, respectively. Concurrently, a second movable electrical contact carrying means is arranged to cooperate with the other or second leg of the armature to produce a motion of a second electrical contact between a first and a second position in response to an energized and deenergized state of the coil, respectively. The coil is located in respectively. The coil is located in the bight of the U-shaped armature with the pivoted first leg being urged by a spring away from the coil. Since the legs of the armature are on opposite sides of the coil, the motions of the first and second arms induced by the coil are in the same rotational directions. Fixed electrical contacts are arranged to cooperate with the first and second movable contacts to produce corresponding electrical connections therewith in the first and second positions of the first and second movable contacts.

Electromagnetic relay structure

SPECIFICATION RELAY STRUCTURE ABSTRACT OF THE DISCLOSURE A relay structure advantageous for compacting purpose is disclosed herein. The relay comprises a generally L-shaped yoke having an upright yoke leg and an upper yoke member extending substantially at a right angle thereto, the upright yoke leg being connected to one end of the core of an energizing coil which extends substantially in parallelism with said upper yoke member. The upper yoke member is formed with a center slot extending longitudinally thereof to be open at both longitudinal ends. A generally L-shaped armature is hingedly supported onto the free end of the upper yoke member with a tab extending across the air gap defined between the free end of the upper yoke member and the opposite end of the core. Extended from the upper end of the tab is an actuator arm which is received in said slot and on which overlies a spring blade carrying at its free end a movable contact. Upon hinging movement of the armature in one direction in response to the coil being energized, the actuator arm presses upwardly the spring blade to engage or disengage the movable contact from a cooperating fixed contact. Conversely, when the coil is deenergized the armature is driven to hinge in the opposite direction by the biasing force from the spring blade to disengage or engage the movable contact with the fixed contact. During this hinging movement of the armature, the actuator arm of the armature is kept substantially within said slot in the upper yoke member, requiring no additional spacing above the yoke for the the movement of the armature. That is, the thickness of the actuator arm can be substantially received within the upper yoke member so as to reduce the total thickness or height, presenting a very compact arrangement with respect to the height of the relay.
