Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a polarized relay.

[Background technology]

In recent years, there has been a desire for electronic devices to be lighter, thinner, shorter, and smaller, and in order to promote this, components such as semiconductor elements and relays used inside the devices are being packaged in high density. However, in conventional bran HV relays, the coil frame 1, contact block 3, and armature block 2 are separately arranged on the base 4 as shown in Fig. 3, so the mounting area is large and the mounting density is high. There was a problem that it was not possible to

[Purpose of the invention]

In view of the above circumstances, it is an object of the present invention to provide a small-sized polarized relay that can be mounted at high density and occupies a small surface area.

[Disclosure of the invention]

The present invention provides a polarized relay consisting of an armature block consisting of an armature and a permanent magnet, a contact block consisting of a movable contact spring and a fixed contact, a coil frame wound with a coil μ, and a yoke, in which a collar portion of the coil frame is provided. The device is characterized by having a contact block capable of opening and closing contacts on the outer surface, and the armature block that drives the contact block by excitation of a coil, and is small and compact and occupies only a small area. Can: Construct a small polarized relay.

An embodiment of the present invention will be described below based on the drawings.

As shown in FIG. 1, the polarized relay of the present invention includes an armature block 1 and a contact block 4 disposed on the collar of a coil frame 6 engaged with a yoke 7, and a case lO It is composed of the following.

The armature block l has a substantially U-shape as a whole with a permanent magnet interposed between the armatures za and zb, and is fixed and fixed on a movable contact spring 5, which will be described later. In this example, the armatures 2b and 2b have different longitudinal dimensions and form a single-type polarized relay, but it goes without saying that if they have the same dimensions, a futching type can be formed. . The contact block 4 has a substantially rectangular planar shape with a window hole 5f in the center, and a movable contact spring 5 and a fixed contact 8.
It becomes more. Two corresponding sides of the movable contact spring 5 are each provided with a two-handed notch, and a pair of movable contacts are bent 90' on both short sides of one of the notches and extended outward. Boards sb and sb are formed. Movable contacts 5a, 5 are provided on the outer surface of the free end of the movable contact plate sb, sb.
A is attached and is opposite to the fixed contact 8.8. Further, a fixing portion 5C fixed to the tip end of the one-way 7a of the yoke 7 is formed on one of the other short sides of the notch. This fixed portion 5C is connected to the movable contact spring 5 via the rocky portion 5g. A hole 5d serving as a pivot point is formed in one corner of the movable contact spring 5 on the side where the fixed portion 5C is provided. Further, on the lower surface of both corners of the side where the movable contact plate 5b is formed, arc-shaped protrusions 5e, 5e pushed out from the top are formed as shown in FIG. When the coil frame 6 is moved, the protrusions 5e and 5e come into contact with and slide against the surface of the coil frame 6, so the friction between the two is reduced and stable rotation is possible.

The shapes of the protrusions 5e and 5e are not limited to this embodiment and may be any shape as long as the movable contact spring 5 can rotate smoothly.

The coil frame 6 is approximately H-shaped as shown in FIG. 1, and a carp (vu) is wound around the mid-abdomen. One collar 6b of the coil frame 6 is formed with a cylindrical protrusion 6a that passes through the hole 5d of the movable contact spring 5. Also, at both corners of one side of the other flange portion 6C, there are coil terminals L! which are connected to the coil I11! , 12 are penetrated and fixed, and are formed to protrude outward from the bottom surface of the collar portion 6C. Also, the coil terminal 12
．． 12 is formed, but it is press-fitted and fixed. The other side iron core part 7b of the yoke 7 is the hollow part 6d of the coil frame 6 marked Uσ.
The iron core shaft is provided so as to intersect with the collar 6b, and the tip protrudes from the outer surface of the collar 6b. It is absorbed and released. Further, a long and narrow common terminal 7C is formed at the bottom of #7B on one side. A part of the fixed contact terminal 9.9, which has the pair of fixed contacts 8 fixed to the upper part, is press-fitted onto the opposite sides of the upper and lower ribs sb and sc, whose one side e73 is press-fitted and fixed.

The operation of the present invention will be explained below. When current is applied to the coil 11, a repulsive force is generated between the armature block 1 fixedly fixed to the movable contact spring 5 and the yoke 7, and the armature block 1 and the yoke 7 are attracted or released, so that the movable contact spring 5 The movable contact 5 is rotated in parallel about the part 6a as a fulcrum.
A is invertedly contacted from one side to the other stationary contact 9. Also, when the current is cut off, the armature block 1 becomes unbalanced in the magnetic resistance between the armatures 2a, 2b and the yoke 7.
As a result, the movable contact 5a returns to its original position, and the movable contact 5a also comes into contact with the original fixed contact again. As described above, in this embodiment,
Although the contacts were opened and closed by rotating the movable contact spring engaged with the armature block, this embodiment would work if the contacts could be opened and closed by the contact block and the armature block within the area of the collar of the coil frame. It is not limited to.

〔Effect of the invention〕

In the present invention, as described above, by arranging the armature block together with the contact block that can open and close the contact on the outer surface of one of the flange parts of the coil frame, it is possible to reduce the mounting area that was conventionally occupied by these two blocks. Therefore, it is possible to construct a polarized relay that occupies an extremely small area and is ideal for high-density packaging.

Furthermore, by arranging each block to the coil frame, the pace parts that were previously required are no longer necessary, and the number of parts used can be reduced, streamlining parts management and reducing costs. It is useful to be able to do so.
