問題があつた。[Background Art] Generally, as shown in FIGS. 8 and 9, in an electromagnet device, an armature 25 is connected to and separated from an iron core 23 around which a coil 21 is wound as the coil 21 is energized. Coil 2
The armature 25 is biased by a return spring 27' so that the armature 25 separates from the iron core 23 when the armature 1 is in a non-energized state. Since the conventional return spring 27' was formed by a coil spring,
The space occupied by the return spring 27' tends to be large, and if a certain amount of space is required around it for installation work, etc., the so-called dead space becomes large, creating the problem that the electromagnet device cannot be made smaller. was. Furthermore, when an impact force is applied in the direction of arrow A in FIG. 9, the armature moves in the direction of A, causing the return spring 27' to stretch or come off. It was hot.
Furthermore, since the return spring 27' has almost no force restraining the armature 27 in the B direction in FIG.
If the armature 25 is moved into and out of contact with the iron core many times, the pivot portion of the armature 25 may wear out or the operating characteristics of the electromagnetic device may deteriorate. There was a problem with instability.

を行なうのである。(Example 1) As shown in FIGS. 1 and 2, case 10
consists of a base 11 and a cover 12 that is fitted onto the base 11, and a contact device 30 is mounted on the base 11.
and an electromagnet device 20 which is a contact drive unit that drives the contact device 30. Electromagnetic device 20
is a cylindrical coil frame 22 around which a coil 21 is wound.
An iron core 23 is inserted into the coil frame 22. A yoke 24 is coupled to one end of the iron core 23, and the yoke 24 covers one end surface of the coil frame 22 and extends around the side surface of the coil frame 22 to face the vicinity of the other end of the iron core 23. It is formed into an approximately L shape. An armature 25 is pivotally supported in a portion of the yoke 24 facing the vicinity of the iron core 23. The armature 25 is bent at one end on the base side, and an insertion hole 25a is formed at this bent portion. The tip of the armature 25 can be brought into contact with and separated from the other end of the iron core 23. The armature 25 is coupled to a holder 26 made of a synthetic resin molded product together with movable plates 36a to 36c, which will be described later, and is urged away from the other end of the iron core 23 by a return spring 27. There is. The return spring 27 has a fifth
As shown in the figure, a spring piece 27b whose tip is bridged extends from the upper end of the holding piece 27a,
A locking piece 27c projects from the holding piece 27a at a portion surrounded by the holding piece 27a and the spring piece 27b. The tip of the spring piece 27b is bent toward the base of the armature 25, and the tip of the locking piece 27c is bent toward the tip of the armature 25. Furthermore, a raised piece 27d is formed in the center of the holding piece 27a. Coil frame 22 and yoke 24
The lower end is inserted into a recess 13 opening on the upper surface of the base 11, and is held by a holding rib 14, which stands up on the upper surface of the base 11 and has a substantially U-shaped horizontal cross section. The armature 25 is pivotally supported at the tip of the yoke 24 in the vicinity of the bent portion, so that it can swing freely.In this state, the holding piece 27 of the return spring 27
a is inserted between the yoke 24 and the holding rib 14 through the insertion hole 25a. An engagement notch 14a is formed on the surface of the holding rib 14 facing the yoke 24.
The return spring 27 is prevented from coming off by engaging the cut and raised piece 27d of the return spring 27 with a. Here, as shown in FIG. 4, the return spring 27
The spring piece 27b contacts the opening edge of the insertion hole 25a to press the armature 25 against the yoke 24, and urges the tip of the armature 25 to move away from the iron core 23. Further, the locking piece 27c is arranged so as to hang over the opening edge of the insertion hole 25a to prevent the armature 25 from floating up. That is, as shown in FIG.
c is slightly away from the top surface of the armature 25,
Although the swing of the armature 25 is not hindered,
When an impact force is applied in the direction of arrow A in FIG. 3, the armature 25 is prevented from floating above this gap. Furthermore, the holding piece 27
As shown in FIG. 3, the position of the insertion hole 25a is set so that the portion from a to the locking piece 27c is bent toward the base of the armature 25. Therefore, the armature 25 is always positioned at the position shown in FIG. It will be biased to the left inside. That is, the inner peripheral surface S 2 of the insertion hole 25 a is located on the base side of the armature 25 with respect to the side surface S 1 of the yoke 24 . As a result, even when a force in the B direction is applied to the armature 25 (mainly caused by the attractive force between the iron core 23 and the armature 25), the armature 25 does not wobble and can oscillate stably. It performs moving actions.

By the way, armature 2
Three movable plates 36a to 36c are attached to the holder 26 provided at the base of the holder 26, and among these movable plates 36a to 36c, the central movable plate 36b,
Alternatively, movable springs 35 are attached to the movable plates 36a and 36c at both ends. A contact holding plate 34 made of a conductor is fixed to each movable spring 35.
A movable contact 33 is fixed to each end of the . Further, the terminal piece 31a of the fixed contact plate 31 is inserted into the base 11, and a fixed contact 32 facing the movable contact 33 is fixed to each fixed contact plate 31. Therefore, coil 2
1 is energized, the two fixed contact plates 31 are electrically connected via the contact holding plate 34, and the pair of fixed contacts 32 and the pair of movable contacts 33 form a normally open contact.
