Description

[Detailed description of the invention] 〔Technical field〕 This issue 1 relates to a polar electromagnet device.

[Background Art J Conventionally, this type of polarized electromagnet device is a balanced armature type in which an armature formed using a permanent magnet is rotatably held, and the armature is rotationally driven in a predetermined direction by the electromagnet. there were. However, in such conventional examples, the armature is formed using a permanent magnet and a yoke made of soft magnetic material, which increases the complexity and cost as well as increases the weight of the armature. There was a problem that the opening characteristics became worse due to the larger size.

[Purpose of the invention] Kibori J was created in view of the above points, and its purpose is to create a polarized electromagnet with a simple structure, low cost, impressive design, and good opening characteristics. The goal is to provide equipment.

[Disclosure of the invention]

(Embodiment 1) Figure 1 shows an embodiment of the present invention, in which (1) shows an E-shaped yoke (3
) is formed by winding an excitation coil (4) around the central piece (convex a), and (5) is a U-shaped armature that is made of soft magnetic material and can swing freely. Type yoke (
3) Medium flame pieces (3a)c! : Each leg piece (5aX5b) of the armature (5) is inserted between the two side pieces (3bX3c).
The electromagnetic block (1) and the armature (5) are arranged so that the armature (5) is located so that the armature (5) is driven in a predetermined direction by the excitation of the electromagnetic block (1), and the armature (5) is positioned by the permanent magnet (2aX2b). 5
) is latched at a predetermined position 1H.

Figure 2 shows the operation. As shown in figure (a), when a DC voltage is applied to the excitation coil (4) so that a magnetic flux in phase with the magnetic flux OB of the permanent magnet (2b) is generated, the armature ( 5) is driven in the direction of arrow B, and the armature (5) is driven in the direction of arrow B.
) are latched in a state in which the leg pieces (5a) and (5b) of the E-shaped yoke (3) are in contact with the center piece (3a) and the side pieces (3C), respectively. That is, even if the excitation of the excitation coil (4) is released, the armature (5) is held at the previous excitation state fθ by the permanent magnet (2b). Next, as shown in the same figure (b), the magnetic flux OA of the permanent magnet (2a) is equal to 4
When a DC voltage is applied to the excitation coil (4) to generate magnetic flux, the armature (5) moves in the direction indicated by the arrow! The leg pieces (5a) (5b) of the armature (5) are
It is latched while in contact with the center piece (3a) and side pieces (3b) of the letter-shaped yoke (3), respectively.

Figures 3 to 6 show a latch relay formed using the multistable polar electromagnetic device obtained as described above, and a U-shaped composite structure that wraps around the armature (5). A resin molded body (6) is attached, and contact drive protrusions (7a) (
7b) are protruded, and contact drive protrusions (7aX7b) are provided in the guide notches (8a) and (8b), which are V-shaped on both sides (convex B) and (Convex C) of the E-shaped yoke (3), respectively. The armature (5) is slidably fitted into the armature (5).
is designed to slide smoothly in the direction of the arrow. In the figure, (9) is a contact block consisting of a fixed contact OQ" and a reversing contact spring ov, and is driven by the I3r!#I contact spring (]υ or the contact drive protrusion (7a) (7b). 4 is the body to which the contact block (9) and the electromagnetic screw (1) are attached, (b) is the cover, and O is the terminal hinge.

(Example 2) The seventh example shows another example, in which the permanent magnet (2a) in Example 1 is omitted to form a monostable state electromagnet device. As shown in Figure 8(a), the armature (5) is fixed by the permanent magnet (2b).
is attracted and latched in the direction of arrow B, and 'yJi 6M
When a voltage with a polarity that generates a magnetic flux in a direction that cancels the magnetic flux βB of the permanent magnet (2a) is applied to the coil (4), the armature (5) is pulled in the direction of arrow A K11k, and the armature (5) is pulled in the direction of arrow A K11k. Both leg pieces (5aX5b) come into contact with the center piece (convex a) and side piece (convex b) of the E-shaped yoke (3). Next, when the excitation is removed, the armature (
5) returns to the state shown in (a) of the same figure, and monostable operation is performed. In addition, it is possible to form a monostable type relay using this polar electromagnet device.

[Effect of the starting J] As described above, the present invention provides an E equipped with a permanent magnet for starting and starting.
The center piece of the E-shaped yoke is made up of an electromagnetic "jOtsuku" formed by winding an excitation coil around the center piece of the E-shaped yoke, and a swingable U-shaped armature made of soft magnetic material. An electromagnetic block and an armature are arranged so that each leg of the U-shaped armature is located between the two side pieces, and the armature is driven in a predetermined direction by the excitation of the electromagnetic block, and The armature is latched at a predetermined position ttl,
Since the armature is formed only from a U-shaped soft magnetic material, the armature structure is simpler than conventional balanced armature type/polarized electromagnetic devices, and the weight is lighter, providing impressive open characteristics. There are some benefits that can be improved.
