性体ＬＯを取着している。Conventionally, as shown in FIGS. 5A and 5B, this type of silence relay has a rod-shaped iron core 3 inserted into a coil frame 7 around which a coil 1 is wound, and one end of the iron core 3 is connected to a stub-shaped yoke 2. At the other end of the yoke 2, an abbreviated armature 4 is supported in the middle.At one end of the armature 4, a movable contact 5a facing a fixed contact 6 is connected. A fixed movable contact spring 5 is attached, and a magnetic elastic body LO such as a magnetic rubber for sound deadening is attached to the surface of the iron core 3 facing the magnetic pole surface 3a.

。When the coil 1 is excited, one end of the armature 4 is connected to the iron core 3.
The magnetic elastic body 10 is attracted to the magnetic pole surface 3a of the iron core 3 and eventually comes into contact with the magnetic pole surface 3a of the iron core 3, as shown in the same figure (bl).
As the armature 4 moves, the movable contact 5a of the movable contact spring 5 attached to the armature 4 comes into contact with the opposing fixed contact 6. Also, when the excitation of the coil 1 is stopped, 4 (not shown) occurs.
Amateur 4 returns to its original position by means of screaming.

があった。The noise reduction relay explained in the conventional example has a magnetic elastic body such as magnetic rubber on the surface of the armature 4 that faces the magnetic pole surface 3a of the iron core 3! 0
is provided to prevent direct metal contact between the iron core 3 and the armature 4 to muffle the sound, and to reduce the magnetic resistance of the entire magnetic circuit by using magnetic rubber as the elastic body for sound muffling. Although it has the advantage of suppressing the increase as much as possible, the magnetic resistance of magnetic rubber etc. is higher than that of magnetic materials such as the iron core 3, and the elastic force of the elastic body lO
Since the coil acts in the direction of pulling it away from the suction surface, the suction stability when the armature 40 comes into contact with it deteriorates, and the armature 1a 4 momentarily separates from the iron core 3 due to external vibrations and shocks, which causes the coil to There has been a problem in that a so-called contact open state occurs in which the movable contact 5a momentarily opens from the fixed contact 6 even though the movable contact 5a is energized.

しまうという問題があった。In addition, in order to eliminate the above-mentioned drawbacks, it has been considered to add more ferromagnetic powder into the magnetic elastic body 10 to improve the magnetic permeability of the entire magnetic elastic body m, but in this case,
As the rigidity of the magnetic elastic body 1O increases, the contact noise when it comes into contact with the iron core 3 becomes higher, and this creates a conflicting problem in which it is argued that it would be better to reduce the noise. Furthermore, since they are rigid, there is a problem in that the contact bounce becomes high when they come into contact.
本発明は前記問題点に着目し改善を図ったものであって
その目的とするところは、磁気効率が良く特性の安定し
た消音リレーを得るにある。The present invention has been made to address and improve the above-mentioned problems, and its purpose is to obtain a noise reduction relay with good magnetic efficiency and stable characteristics.
前記目的を達成するため本発明の消音リレーは少なくト
モ鉄芯とアマチュアとの当接部のいずれか一方に磁性流
体を封入した可撓性薄膜を設けている。In order to achieve the above object, the noise reduction relay of the present invention is provided with a flexible thin film filled with a magnetic fluid on either one of the abutment parts between the iron core and the armature.

芯に当接させることができる。A flexible thin film filled with magnetic fluid is interposed between the iron core and the armature, which are attracted by metal comrades, so when the armature is attracted to and touches the iron core, it acts like a so-called rubber balloon filled with water. As the magnetic fluid enclosing film is compressed and attracted, the armature is decelerated and comes into contact with the iron core, resulting in extremely low noise during operation. Furthermore, when the armature and the iron core are attracted to each other, the magnetic fluid concentrates on the part where the magnetic flux is highest, that is, the central part of the iron core, rises toward the armature, and lifts up the enclosed thin film, so that the magnetic gear 4
-j becomes extremely small, magnetic efficiency can be increased, and since there is no force acting to repel the attraction force of the armature after the armature is attracted to the iron core, a stable attraction force can be obtained. Furthermore, a part of the iron core and yoke is provided with a storage part for the magnetic fluid-filled membrane, and when the armature is completely attracted, the magnetic fluid is stored in the storage part, so the armature can be brought into direct contact with the iron core. .

A thin film 9 made of a flexible resin such as the above is covered for inspection. The thin film 9 is provided with a reservoir 9a on the side of the magnetic pole face 3a, in which the magnetic fluid 8 accumulates when the coil 1 is not energized.

The magnetic gap between the iron core 3 and the armature 4 can be magnetically connected with the magnetic fluid 8. When the armature 4 is in operation, the magnetic gear 9 with the iron core 3
The magnetic resistance can be lowered by eliminating or making them extremely small. As the suction movement of the armature 4 further progresses, the armature 4 is sucked while crushing the thin film 9 containing the magnetic fluid 8, that is, the operation speed is suppressed and decelerated, as if crushing a rubber balloon filled with water. As shown in FIG. 4(c), the magnetic fluid 8 accumulates in a pool 9a of the thin film 9, and the armature 4 comes into contact with the iron core 4. At this time, a thin film 9 is interposed between the armature 4 and the iron core 3, but because it is extremely thin, there is no increase in magnetic resistance and there is almost no problem with the suction stability of the armature 4. or,
In order to further increase the magnetic attraction force, ferromagnetic particles may be added to the thin film 9 to form a mother thin film. When the excitation of the coil 1 is stopped, the armature 4 is
is a monostable relay that returns to its original position.

る。3 and 4 each have a concave storage portion 3b that stores the magnetic fluid 8 when the armature 4 is attracted to the iron core 3, approximately at the center of the magnetic pole surface 3a of the magnetic fluid 8. As a result, the armature 4 can finally come into direct contact with the magnetic pole face 3a of the iron core 3, and the thin film 9 can be easily attached to the inner bottom of the housing part 3b with adhesive or the like, making assembly easy. In addition, in FIG. 4, the housing portion 3c of the thin film 9 is provided on the outer periphery of the iron core 3 except for the center. can be adsorbed, and the adsorption stability of the armature 4 can be increased.
