Description

Detailed Description of the Invention (Technical Field) The present invention provides a permanent magnet in a magnetic circuit composed of an armature and a yoke, and superimposes the magnetomotive force of a coil on the magnetic flux of this permanent magnet, thereby increasing the armature. The present invention relates to a so-called moving polar electromagnetic ff1fi electric appliance, and particularly to a polar electromagnetic B electric appliance in which an armature is horizontally reciprocated.

(Background Technique 1.ll:i) General polarized electromagnetic phase; the electric appliance is rotatably supported at the center of the amadate, and the armature swings to connect the two polarized poles of the yoke at diagonal positions. It has a structure that makes contact with the surface.

In a polarized electromagnetic relay with such a structure, if the three points of both diagonal armature surfaces of the armature and the center pivot shaft are not maintained accurately due to dimensional accuracy, only one armature surface will come into contact. This phenomenon occurs, and this has the problem of causing 'rb'.

Therefore, 4jl, 7, which moves this armature horizontally back and forth.
It has already been proposed to solve this problem by adopting a new structure.

For example, Patent Application Publication No. 41005 of 1980 issued by the Japan Patent Office (hereinafter referred to as the first prior art) has been proposed.

To explain this with reference to FIG. 12, the two pieces 102, the middle piece 103, and the lower piece 1-04 form an I-shaped yoke 101, the middle piece 103 is equipped with a coil 105, and the upper, middle, and lower parts are
A permanent magnet 106 that also serves as a common armature is faced to each of the pieces 102, 103, and 104, and the direction of magnetic flux due to this permanent magnet 106 is indicated by X, and the direction of magnetic flux due to coil 105 is indicated by Y. direction.

Therefore, each month 102, 103, 104 and permanent magnet 106
The magnetic flux directions X and Y of the gap are opposite to each other and immediately repel each other, and the permanent magnet 106 as an armature is horizontally moved in the direction of the arrow Z.

Subsequently, when a coil current flows so that the magnetic east direction of the coil 106 is opposite to the magnetic flux Y of the permanent magnet 106, the magnetic flux Y of the permanent magnet 106 is superimposed on the permanent magnet 106, which is an armature.
is attracted.

In this first prior art polarized type 21 magnetic S electric appliance, since the magnetic flux of the coil 105 passes through the permanent magnet 106, it has the following problem.

In other words, the magnetic resistance of the permanent magnet 106 is about 10,000 times higher than that of a general yoke (iron), and the loss rate of the magnetomotive flux of the coil 105 is high.Therefore, there is a problem in increasing the sensitivity of the device. be.

In order to solve the above-mentioned problems, an Ffi type τh magnetic relay having a structure as disclosed in French Patent No. 235800 (No. 3 Specification Shell 1 (hereinafter referred to as the second prior art)) has been proposed.

This is an advantage of high sensitivity due to the fact that the magnetomotive flux of the coil does not pass through the permanent magnet.

To explain this according to FIG. 13, the left and right vertical magnetic pieces 202, 203 and the core 210a constitute a U-shaped yoke 201, a permanent magnet 207, and a first magnetic piece 205 in contact with one pole of the permanent magnet. The armature block 204 is made up of the second magnetic piece 20G in contact with the other pole of this permanent magnet, and the magnetic piece 20 of fEl
5 is formed in a U-shape, and its left and right hanging portions 1) A piece portions 208.
209 is the left vertical magnetic piece 20 of the U-shaped yoke 201;
2, facing the outer surface of 203. Second magnetic piece 2
0 (3 is the left and right vertical pieces 202 of the U-shaped yoke 201,
203, facing the inner surface of this first. Second magnetic piece 205
A permanent magnet 207 is held between the two. coil 21
0 is mounted on a U-shaped yoke 201.

In the case of this second prior art, the magnetic flux X due to the permanent magnetic flux 207 is transmitted from one pole of the permanent magnet 207 to the armature block
The two magnetic paths return to the other pole of the permanent magnet 207 via the first and second magnetic pieces 205 and 206 of 04, and the second magnetic path of the armature block 204 from one pole of the permanent magnet 207.
Permanent magnet 207 via magnetic piece 206, U-shaped yoke 201, and first magnetic piece 205 of armature block 204
through the magnetic path back to the other pole of the coil 210
The magnetic flux generated by
, the permanent magnet 207, the second magnetic piece 206, and the left vertical piece 202 of the U-shaped yoke 201 (the left vertical piece 203 when the armature block is reversed).

Therefore, the armature block 204 and the U-shaped yoke 20
1) - both magnetic flux directions x
, y are repelled when they are in opposite directions, and are pulled when they are in the same direction. Therefore, the armature block 204 horizontally moves left and right depending on the current direction of the coil 210.

As is clear from the figure, this second prior art has a permanent magnet 2
07, the magnetic flux Y of the coil 210 does not flow to the first
This solves the problems in the prior art.

However, this prior art F52 has other problems due to the adoption of a structure in which one permanent magnet is included in the armature block.

That is, since the permanent magnet is included in the armature block that is driven to drive the contact point, the permanent magnet 207 is heavy and the operating speed of the armature block is slow, and the size of the block is further increased. The force increases and vibrations are promoted. Also, due to the relationship with the weight, the characteristics become unbalanced depending on the direction in which it is taken.

Other problems with this second prior art are as follows. That is, the second part of the amateur block 204 (Konomi yoke 20
1 exists, and the armature block 204 requires a permissible space above and below the guide during its horizontal reciprocating movement, so it is drawn toward the yoke 201 due to the division of space.

Therefore, depending on the mounting condition, the direction of the yoke 201 changes, and due to the overlapping position of the armature block 204, the characteristics may be unbalanced as in 1. l: Ru.

Further, the implementation of horizontal reciprocating of the armature in a polarized heavy magnetic relay η has not yet been disclosed.
And it's not easy.

As a third prior art, for example, US Patent No. 27948
There is a specification of No. 82, which is a so-called non-polar electromagnetic relay that is not equipped with a permanent magnet.

(Disclosure of the Invention) The present invention is directed to these conventional polarized ILs (6K ft'l
? At the same time as solving the gambling problem that occurs in the
fIi type? I1 for the manufacture and application of It magnetic relays
We provide convenient polarized Fil magnetic relay electrical appliances. According to the present invention, a permanent magnet is interposed between the first yoke and the ff12 yoke, and this f(gl, the second yoke, and the permanent magnet are arranged one above the other as one block, and the upper and lower ffJl, 1'r!
By connecting the left and right side pieces that face and separate from the left and right armature surfaces of the two yokes and forming a horizontally moving type armature with a horizontal rod that passes through the coil, the advantage of the horizontally moving IPJ armature is utilized. This will lead to new development.

Another object of the present invention is to reduce the loss rate of the magnetic flux of the coil by preventing the magnetic flux of the coil from passing through the permanent magnet, thereby achieving high sensitivity.

Another object of the present invention is to minimize the mass of the armature without equipping the amadate with a permanent magnet, thereby increasing the operating speed of the armature.

Another object of the present invention is to maintain balance by arranging yokes and permanent magnets above and below the armature, and to prevent fluctuations in operating sensitivity due to the J direction.

Another object of the present invention is to implement a polarized electromagnetic shaft of the type in which the armature is moved horizontally.

1 to 11, the first yoke 1 has left and right pieces 2.3, and left and right pieces 2.3.
3 are connected in a U-shape, and the left and right side pieces 2.3 have their inner surfaces connected to the polarized surfaces 2a, .
3a. The yoke 5 of the pain S2 has a length shorter than the distance between the left and right pieces 2.3 of the first yoke 1, and faces the horizontal piece 4. The left and right outer surfaces of the second yoke 5 serve as armature surfaces 5a and 5b. The permanent magnet 6 is interposed between the first yoke 1 and the second yoke 2, and its magnetization axis direction is perpendicular. This first
The second yokes 1 and 5 and the permanent magnet 6 are arranged one above the other as one block. The armature 7 is of a horizontal transition type, and is formed into a type II shape with left and right side pieces 8.9 and a horizontal bar 10 that connects the left and right side pieces 8.9, and the left and right side pieces 8, 9 are arranged inside and outside. Both sides are polarized surfaces 13a.

3b, 9a, 9b. The inner and outer contact surfaces 3a, 3b, 9a, 9b of this left and right side piece 8°9 are +)
Inner and outer contact surfaces 2a and 3a of the first and second yokes 1.5.

Facing 5a and 5b, air gaps a, b,

d to each of the six coils 11 and the horizontal rod 10 of the armature 7.
is penetrated.

The magnetic circuit between the permanent magnet 6 and the coil 11 is shown in FIG.

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

N pole of permanent magnet 6 → second yoke 5 → air gear), knobs b and C → left and right side pieces 8.9 of armature 7 → air gap λ, d - left and right side pieces of first yoke 1 2°3 → horizontal piece 4→
Becomes the S pole.

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

Coil 11 → horizontal rod 10 of armature 7 → left side piece 8 → air gap λ → left side 2 of first yoke 1 - horizontal piece 4 → right side piece 3 → air gap d → right side piece 9 of armature 7 → horizontal rod 10 Become.

Also, from the left side piece 8 of the armature 7 to the air gap b + second
Yoke 5 → Air gap C → Right side piece 9 of armature gear 7 →
It also serves as a horizontal bar 10.

So, when we observe the air gaps a, b, c, and d, we find that
The directions of the magnetic fluxes X and Y of the permanent magnet 6 and the coil 11 are the same in the air gap λ and C, and the air gaps b and d are in opposite directions.

Therefore, the first. The second yoke 1.5 and the armature 7 have magnetic fluxes X and Y superimposed in the same direction and an attractive force acts on them, and in the opposite direction they cancel each other out and have a repulsive force, so in Fig. 1, the armature 7 The outer contact surface 8a of the left side piece 8 of the armature 7 and the left side piece 2 of the first yoke 1 move horizontally to the left as indicated by arrow Z.
The inner contact surface 2a of the armature 7 is attracted to the right side 9 of the armature 7.
The inner contact surface 93 of the second yoke 5 and the outer contact surface 51 of the second yoke 5 are attracted to each other.

This attracted state is maintained by the magnetic flux of the permanent magnet 6 even if the current flowing through the coil 11 is cut off.

When moving the armature 7 horizontally to the right, contrary to the above, a current in the opposite direction to the above is passed through the coil 11, and the magnetic flux Y
acts in the opposite way to that shown in Figure 1.

The air cavities λ, b, c, and d are reversed, with air gaps a and c in opposite directions, air gaps b and d in the same direction, and armature 7 is shown in the direction of arrow W.
Shift horizontally to the right as shown by .

The adsorption state is maintained by the magnetic flux of the permanent magnet 6, which has the same number as in Part 2.

From this observation, the magnetomotive flux Y of the coil 11 does not pass through the permanent magnet 6, which has a large magnetic resistance, resulting in high sensitivity. Moreover, the armature 7 operates independently without fixing the coil 11 and the permanent magnet 6, and the amount of buying is kept to a minimum.

2 to 5 are implementations of the basic principle of FIG. 1.

The upper and lower first yokes 1 are housed in a box 12 made of synthetic resin and having an open top.

In this case, the upper and lower f81 yokes 1 are the 1115th! Sit on the bottom wall 13 of Box E 2 with the left side rotated 90 degrees, and the left side on the four side walls 14! □Side piece 2.3, horizontal piece 4
touches.

The winding frame 15 of the coil 11 has the following structure.

The coil 11 is wound around a winding trunk 16, and the winding trunk 16 has a hole 17 through which the armature 7 passes, and side walls 18 and 19 are formed integrally with the winding trunk 16 on the left and right sides. side wall 1
8. The second yoke 5, which is parallel to the coil 11 and located below -CA, is fixed in a state rotated 90 degrees from FIG. 1 over a period of 8.19. Cutouts 20 are provided in the left and right side walls 18 and 19 to facilitate fitting and fixing of the second 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 material is placed over and fixed to the upper opening of the box 12. An absolute gamma star plate 24 is interposed between the cover 23 and the box 12.

This) J bar 23 has the following A1ζV construction.

The cover 22 has an upper wall 25, a side wall 26 including lowered side walls, and an external separate 27 which is divided into a plurality of parts, and an external separate 27 that is the same as the external separate 27. With the internal separate 28 at the position and the lower opening cavity 29 that crosses this internal separate 28,
; has become.

External terminal fittings 30 are fixed to both outer chambers divided by both side walls 26 and external separates 27 of the cover 23. The terminal fittings 30 on both sides of the rightmost end have integrally formed vertical plug blades 3J, and when the cover 23 and the box 12 are combined, the receiving terminal fittings 22 of the coil winding frame 15 can The electrical connection with the coil 11 is completed. The other terminal fitting 30 is provided with a fixed contact 32, which is located in internal chambers 33 on both sides divided by an internal separate plate 28.

In addition, in the cavity 29 of the lower opening of the cover 23, there is a composite A.5.1
A movable platform 3 that moves parallel to an armature 7 made of fat.
4 is located.

This movable base 34 has a through-hole 35 formed at a position corresponding to the inner chamber 33 of the cover 23, and a contact plate 36 with protruding contacts 37 on both sides and a coil spring for contact pressure are installed here. It is equipped with 38. Contact point 3 of this movable base 34
7 and the contact point 32 of the cover 23 face the inner chamber 33, and are separated when the movable base 34 moves.

The movable base 34 is prevented from falling by the insulating plate 24 described above.

The movable base 34 and the armature 7 are coupled by a reversing lever 39.

A shaft 40 passes through the center of the reversing lever 39, and the shaft 40 is supported in a shaft hole 41 in the right side wall 19 of the coil winding frame 15.

In the relationship between the reversing lever 39 and the armature 7, a shaft 42 is passed through the lower end of the lever, the shaft 42 is fitted into the groove 44 of the connecting body 43 from above, and the right end of the armature 7 is inserted into the connecting body 43 to apply the force. It deforms under pressure and becomes a stop portion 7a when pulled out.

The left end of the armature 7 is similarly inserted into the left piece 8 and deformed under pressure, and is prevented from being pulled out l57a. At the same time as this removal is stopped, a non-magnetic regular plate 45 is interposed. This plate 45 cuts both ends of the magnetic characteristic curve of the permanent magnet 6, and uses the most stable range.

In the relationship between the reversing lever 39 and the movable base 34, the upper end 39a thereof is hooked into a cutout 46 of the lower opening.

Therefore, in the m2 diagram, the horizontal shift of the armature 7 is reversed in the right direction as indicated by the arrow Z. /<-39 rotates counterclockwise around the solid shaft 40, and the movable base 34 and the armature 7 moves horizontally in the left direction indicated by the opposite arrow V, and the contacts 32 and 37 of each chamber are brought into contact.The contact is maintained by the magnetic flux of the permanent magnet 6 according to the principle diagram in FIG.

The armature 7 is pressed in the direction of arrow Z by a chevron-shaped flat spring 47. This angle-shaped flat spring 47 has its top portion 47a in contact with the left side stop portion 7a of the armature 7, and both ends 47b in contact with the left side wall 14 of the box 12.

The movable base 34 is compressed by a coil spring 48 in a direction opposite to the direction of the arrow (■). This coil (ne 48 is the movable base 34
It is located between the display column 49 of and the left side wall 26 of force/(-23).

The spring pressures of these two springs 47 and 48 act on the armature 7 and the movable table 34 in opposite directions,
This facilitates separation when the armature 7 attempts to move from the state where it is attracted by the magnetic flux of the permanent magnet 6 to the opposite direction.

The display column 49 of the movable table 37 protrudes from a small hole 50 in the upper wall 25 of the cover 23, and from its position, the internal operation can be confirmed from the bottom.

A terminal cover 51 further covers the upper wall 25 of the cover 23. This terminal cover 51 has driver operation holes 53 for terminal screws 52 in number corresponding to the terminal fittings 30 on both sides.

Also, to install it, put out the drawers 54 on both sides and attach the cover 2.
It is inserted into the small hole 55 in the 1 wall 25 of 3.

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

FIG. 6 will be explained.

This is one of the other embodiments and does not deviate from the basic principle diagram of FIG. WE 1. j 1st in the embodiments shown in Figures 32 to 5. The second yoke 1.5 and the permanent magnet 6 are in the form of a flat plate, and instead of being placed separately under the second yoke 1.5, they are made into a cylindrical shape to reduce the number of parts. In this case, the cylindrical first yoke 57 is divided into a cylindrical body 57a and a cap 57b, which are integrated with a screw 58. This cap 571] is removed to store the cylindrical second yoke 59 and the cylindrical permanent magnet 60.

In FIG. 7, the area of the right armature surface 5[] of the second yoke 5 is made larger than the area of the left armature surface 5a.

This can be done by using the side piece 61 to increase the magnetic flux density to strengthen the magnetic flux of the permanent magnet 6, and to shut off the current of the coil 11 when the armature 7 moves in the direction of misalignment ~'. It is a so-called unidirectional operation type (also called a monostable type) that returns to the direction of arrow Z with the magnetic flux of .

FIG. 8 to FIG. 10 will be explained.

This is a three-way movement type (also called a triple stable type), in which the horizontal rod 10 of the armature 7 is cut in the center to make it symmetrical, and a coil spring 62 is interposed between the left and right molecules 7a and 713. Always press outward to the left and right.

Figure S8 shows the first operating state, in which only the magnetic flux of the permanent magnet 6 is acting, and the left and right molecules 7a, 713 are pressed outward to the left and right by the /4 spring pressure of the coil spring 62, and the air gap a is , tt left and right sides J42 of the first yoke 1,
3 and the left and right side pieces 8.9 of the armature 7 are suctioned together, and the second yoke 5 and the left and right side pieces 8 of the armature 7 in air gaps b and c
．． 9 is between Pi:l;

FIG. 9 shows a second operating state, in which when a current is passed through the coil 11 to cause a magnetomotive flux Y1 in a certain direction, the magnetomotive flux Y1 of the coil 11 and the magnetic flux X of the permanent magnet 6 are generated at air gaps a and C. are in opposite directions, and air gaps b and d are in the same direction.

Therefore, when compared with FIG. 8, only the left molecule 7a moves in the right direction of the arrow W against the coil spring 62, and the Is 2 yoke 5 and the left piece 8 of the left-handed element 7a are attracted, and the right molecule 71 ) continues to be attracted to the right side piece 3 of the first yoke 1. Coil 11? Even if the flow b is cut off, the current state is maintained by the magnetic flux X of the permanent magnet 6.

FIG. 10 shows the third operating state, and if a current is passed so that the magnetomotive flux Y2 of the coil 11 in the opposite direction to that in FIG. 9 acts, the air gap λ is
and the magnetic flux X of the permanent magnet 6 are in the same direction, and are in opposite directions at the air gaps b and CI. Therefore, when compared from FIG. 9, both the left and right molecules 7a and 7b have coil springs 62.
The left side 2 of the first yoke 1 and the left side 8 of the left molecule 7a are adsorbed, and then the second yoke 5 and the right molecule 7b are adsorbed. Even if the 〒1i current of the coil J1 is cut off, the current state is maintained by the magnetic flux X of the permanent magnet 6.

FIG. 11 shows another development of the basic principle of FIG. 1.

In this embodiment, the armature 7 and the movable base 34 are arranged horizontally and parallel to each other below the surface of the armature 7 and the movable base 34 in the embodiments shown in FIGS. 7.34 are arranged vertically on the same axis, one above the other. In particular, the basic part is shown in a cross section taken in the same direction as FIG.

An angle-shaped flat spring 47 sits on the bottom wall 13 of the box 12,
Also, the left side piece 2 of the 1-3-ri 1 is placed on it.

Naturally, when the left side of the Amajito 7 is removed, the stop portion 7a faces downward and faces the top portion 47a of the mountain-shaped flat spring 47. When the armature 7 is pulled out on the right side, the stop portion 7b is oriented in one direction, and a U-shaped connecting body 63 is formed. Second angle-shaped flat spring 6
7, and both ends 67b of the cover 23 are inserted into both receiving stages 68 of the cover 23.
is guessing.

This angle-shaped flat spring 67 exerts the same action 41t as the coil spring 4B in the embodiments shown in FIGS. 2 to 5 on the armature 7 and the movable base 34, which is vertically movable on the same axis as the armature 7. It is. Therefore, the lower chevron-shaped flat spring 47 always presses the armature 7 and movable base 34 upward, and the second chevron-shaped flat spring 67 presses downward. Movable stand 3
4 and the connecting body 63 are connected by passing the shaft 71 through the shaft hole 69 of the both side pieces 65 of the connecting body 63 and the shaft hole 70 of the movable base 34.

The box 12 and the cover 23 are connected by coupling screws 72.

The other contacts 32, 37, terminal cover 51, etc. are the same as in the embodiment shown in FIGS. 2 to 5.
