Abstract

PURPOSE:To provide an electromagnetic relay and its manufacturing method, with which the assembling process can be automated easily. CONSTITUTION:A movable contact 30 is fixed to one end of a movable contact spring plate 29 prepared by curving an elastic conductor into an inverted U form, while the other end of the spring plate 29 is coupled with the top of a common terminal 28 in an inverted L form in such a way that electric connection is held. The movable contact 30 is energized by a restoring force of the spring plate 29, generated when it is deformed inward elastically, in the direction of contacting a normally-closed side fixed contact 21 or in the direction moving apart from a normally-open side fixed contact 23. The bottom of a contact actuating spring plate 44 consolidated in such a way as protruding downward relative to an armature 49 is engaged by the movable contact 30 mounting part of the spring plate 29. With the restoring force of the spring plate 29, the armature 49 is energized in the direction of moving apart from the electromagnetic mechanism part 31. This all can be achieved with no use of any return spring nor soldering works, and automating can be achieved easily.

ことを特徴とする電磁継電器の製造方法。2. A method of manufacturing an electromagnetic relay in which a movable contact is brought into contact with a fixed contact by exciting and swinging the movable mechanism by an exciting operation by energizing a coil of the electromagnetic mechanism, the fixed contact being provided at an upper end. A movable base is formed by forming a base stand in which the provided fixed terminal is provided in a penetrating state by insert molding, and bending an elastic conductor in an inverted U shape at the upper end of the common terminal and providing the movable contact at one end. The other end of the contact spring plate is connected in an electrically connected state, the common terminal is fixedly inserted through the base from above, and the movable contact spring plate is elastically deformed inward to elastically deform the movable contact. Positioned from above so as to face the fixed contact, the electromagnetic mechanism portion is integrally formed with the lower end portion of the conductor embedded in the electromagnetic mechanism portion integrally with the coil connection terminal to which the winding end of the coil is connected. Shi The coil terminal is penetrated into the base from above, or a connecting piece integrally formed at the lower end is joined to the upper end of the coil terminal in an electrically connected state and fixedly mounted on the base, and the contact actuating spring plate is attached. Is integrated with the armature in a protruding state below the armature to form a movable contact unit, and the movable contact unit is magnetically connected to the recessed portion of the armature with the engaging piece of the yoke of the electromagnetic mechanism. It is provided so as to be swingable by engaging with it, and the hooking piece at the lower end portion of the contact actuating spring plate is engaged with the locking projection piece of the movable contact spring plate at the mounting portion of the moving contact, and the moving direction of the moving contact. A method of manufacturing an electromagnetic relay, characterized in that it is engaged from above in a state in which the movement of the electromagnetic relay is received.
