The magnetic circuit between this permanent magnet 6 and the carp) is shown in FIG. 1 as a basic principle diagram, and the solid line X indicates the permanent magnet 6
The dotted line Y is the magnetic flux of the coil 7L'll.

In FIG. 1, the magnetic flux X of the permanent magnet 6 flows as follows (C.

Permanent magnet 6ON +I → Second yoke 5 → Air gaff "b and C → Left and right side pieces 8.9 of armature 7- → Air gaps a, d- + Left and right side pieces 2.3 of first yoke 1 →
Horizontal piece 4 → S darkness.

The magnetic flux Y of the coil 11 flows as follows.

Carp/L'll → horizontal bar 10 of amateur 7 → left piece 8 →
Car gap a-+left side 2 of first yoke 1 → horizontal piece 4 → right side 3 → air gear Y tube d → right side 9 of armature 7 → horizontal rod 10.

At d, the direction is the same, and the first armature 7 horizontally moves to the right as indicated by the arrow W.

The adsorption state is maintained by the magnetic flux of the 1τ permanent grinding stone 6 as described above.

Observing these, the magnetomotive flux Y of the carp/I'll does not pass through the permanent magnet 6 having a large magnetic resistance, resulting in high sensitivity.

In addition, the armature 7 has a carp/L'1ll- and a permanent magnet 6.
All movements are performed independently without fixing, and the number of claws is kept to a minimum.

Figures 2 to 5 are the results obtained by implementing the Itokihara jli shown in Figure 1.

The upper and lower brooms 1 and yoke 1 are housed in a box 12&C made of synthetic resin and having an open top.

In this case, the upper and lower first yokes 1 are rotated 90 degrees from FIG.
In addition, the left side piece 2 and the horizontal piece 4 are in contact with the side wall 14.

We will be purchasing 15 reel frames of Koi 7+/11.

The carp Ivll is wound with 161C on the body and has 91 volumes on the body 1.

The yaw 5 is fixed in a state rotated 90 degrees from FIG. Cutouts 20 are provided to facilitate fitting and fixing of the left and right side walls 18 and 191CVi foil 2 yoke 5. Further, the right side wall 19 is provided with a groove 21 into which a receiving blade terminal fitting 22 to which the coil 11 is connected is inserted.

A cover 23 made of synthetic resin is temporarily fixed to one opening of the box 12. An insulating plate 24 is interposed between the cover 23 and the Bogges 12.

This cover 23 will be purchased next.

The cover 23 has an upper wall 25, lowered side walls 26, and lower walls 25 and 1111g! , 26, and an external seven-layer 1-
27. ! :, consists of an internal separate 28 located at the same position as this external GL (separate 27), and a lower opening cavity 29 that crosses this internal separate 28.

Both sides of the cover 23 (on the wall 26 and on the outside)
In the outer chamber on both sides separated by
30 is fixed. The terminal metals 9 and 30 on both sides 1 at the rightmost end have plug blades 31 on both sides integrally formed, and when the cover 23 and the box 1 are combined, the receiving blade terminals of the coil winding frame 15 It is inserted into the metal fitting 22 and completes the electrical connection with the coil 11.FII bar 4M base metal 3B0 is provided with fixed contacts 32, and both side guides are separated by internal sepa V-1-28. Located at 33.

Further, in the cavity 29 of the lower opening of the cover 23, a movable base 34 is located which moves parallel to the armature 7 made of synthetic resin.

In the same room 33 of the cover 23 as the NJ moving base 34, there is a contact plate 36 with contact points 37 protruding from both sides, It is fully equipped with a coil spring 38 for contact pressure. The contact point 37 of the movable base 34 and the contact point 32 of the cover 23 face each other at the same point 33, and are separated when the movable base 34 moves.

The falling of the movable table 34 is prevented by the above-mentioned insulating plate 24.
The movable table 34 and the armature 7 are connected by a reversing lever 39.

The reversing lever 39 has a shaft 40 in the center. It is supported by the shaft hole 41 of the right side wall 19 of the coil winding frame 15.

In the relationship between the reversing lever 39 and the armature 7, its lower end passes through the VC shaft 42, and this shaft 42 is inserted into the groove 44 of the connecting body 43.
Insert it from above and the right end of armature 7? It is inserted into the connecting body 43 and deformed under pressure to form a pull-out stop portion 7b.

The left end of the armature 7 is similarly inserted into the left piece 8 and deformed under pressure to form a recess 11: a recess 7a. At the same time as this removal is stopped, a non-magnetic V diameter plate of 45 gold is interposed. This plate (V-) 45 is intended to cut both ends of the magnetic characteristic curve of the permanent stone 6 and to use the entire most stable range.

Due to the relationship between the reversing lever 39 and the movable base 34, its upper end 39a is hooked into a cutout 46 in the lower opening.

Therefore, if the armature 7 is at position 2 in FIG. 2 and moves horizontally to the right as indicated by arrow 2, the reversing lever 39 is at the center! lQ

The movable base 34 is pressed in a direction opposite to the direction of arrow V by a coil spring 4BIC. This coil spring 48 is connected to the movable metal 3
It is located between the display column 49 of No. 4 and the left side wall 26 of the cover 23.

The spring pressures of these two springs 47 and 48 act on the armature 7 and the movable ring 34 in opposite directions, and the armature 7 shifts from the state where it is attracted by the magnetic flux of the permanent grinding stone 6 to the opposite direction. It is very easy to pull apart when you try to use it.

The display column 49 of the movable metal 34 protrudes from a small hole 50 in the upper wall 25'' of the cover 23, and from that position, all internal operations can be confirmed from the outside.

A terminal cover 51 is further torn on the upper wall 25 of the cover 23. This terminal cover 51VC has terminal metal fittings 30VC on both sides.
Corresponding number of 'terminal screws 52' through operation holes 53
exists.

In addition, to install it, the hooking claws 54 should be exposed on both sides, and the cover 2 should be installed.

Further, on both sides of the terminal cover 51, skirts 56'fc are suspended between the outer separators 27 of the cover 23 to reduce the exposure force of the terminal fittings 30.

0, in this embodiment, the distance between the center of the winding drum 16 and the center of the armature 7 is made wider than the r-projected corner between the end of the winding drum 16 and the 111i+1 part of the armature 7, so that the winding drum By winding the entire 342 m1 around the winding trunk 16, even if the central part of the winding trunk 16 bends inward, the winding trunk J6 and the armature 7 remain intact.
The movement of the armature 7 will not deteriorate because the entire gap can be secured between the pond and the armature 7.An embodiment of the pond according to the present invention is shown in Fig. 7, that is, 1.
This polarized surface relay has a center part of the armature 7 having a smaller diameter than both ends, so that the distance between the center part of the winding drum part 16 and the center part of the armature 7 is [10] at the end of the winding drum part 16. This is wider than the distance between the Amateur 70 singing section and the other 6.
9. The results and effects are similar to those of the previous embodiment.

As described above, the electromagnet device of the present invention has a coil 7 frame structure consisting of a cylindrical part around which the entire coil is wound and a flange formed in the 11'Tii section of this cylindrical part, and the iJ moving iron core is entirely attached to the cylindrical part. Due to the insertion of the electromagnet device, the central part of the cylindrical part and the i'
ilJ IL! The feature is that the distance between the center of the I iron core is wider than the distance between the end of the cylindrical portion and the end of the RIJ moving iron core, so that the center of the cylindrical portion is turned inward by the winding of the coil. Even if it is bent, a gap can be maintained between the cylindrical part and the movable iron (b), and as a result, it is possible to maintain a clearance between the cylindrical part and the movable iron (b).
