Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a relay, and particularly to a relay in which two sets of contact mechanisms are arranged substantially at right angles on a base surface.

Conventionally, in order to ensure high isolation, two sets of contact mechanisms are arranged approximately at right angles on a base surface, and these contact mechanisms are driven in conjunction with each other. Tokuko Sho 59-4
There is one described in Japanese Patent No. 2926.

In other words, if two sets of contact mechanisms arranged approximately perpendicularly on the base surface are combined to form a roughly square shape, the electromagnetic device rotates in the direction perpendicular to the base surface based on the excitation and demagnetization of the electromagnet device. The see-saw main body of the moving see-saw mechanism unit drives the contact mechanism unit in conjunction with the seesaw body.

However, in this case, the drive unit 1o, such as the main body of the nose unit, rotates in a direction perpendicular to the base surface.
In order to drive the drive member, it is necessary to form a rough drive layer in a direction perpendicular to the base surface, which poses a problem in that it is difficult to make the device thinner.

In order to solve the above-mentioned problems, the present invention provides a contact drive card that rotates in parallel to a curved base surface based on the excitation and demagnetization of an electromagnetic device ξ provided on the base. In a relay that interlocks and drives a first contact mechanism section and a second contact mechanism section arranged at right angles, one side part of the contact drive card is connected to a first contact mechanism part opposite to this side part.
1 [While connected to the first contact mechanism section in item i, 1) One end of the two-shaped drive piece supported so as to rotate in parallel to the contact mechanism part in item 11, is connected to the contact drive card 1iir.
The one side is connected to the other side opposite to the other side, and the other end of the L-shaped drive piece is connected to the front J[! The second contact bar (1 is connected to the part and has an L configuration.

Therefore, according to the present invention, the contact drive card that rotates parallel to the base surface drives the contact drive card through the L-shaped drive piece that rotates parallel to the base surface. The first one is arranged approximately perpendicular to the plane. The second contact mechanism section is driven in conjunction with the second contact mechanism section.

．． 22, they are arranged so as to form a substantially right angle with +4.

Note that the fixed contact terminals 11, 12, 13 and 21.
22 is of course insulated from the conductive thin film of the base 2.

The electromagnet device 30 consists of a spool 31, an iron core 36, a yoke 37, a coil 38, and a coil terminal 39.

The spool 31 has a coil 38 wound between flanges 32 and 33 provided at both ends thereof, and an iron core 36 inserted into the hollow hole 31a, with both ends 36a and 3Gb protruding, respectively.

The yoke 37 has upstanding pieces 37a and 37 provided at one end thereof.
b is the base portion 3 extending from the collar portion 32 of the spool 31;
They are inserted into the insertion holes 3□la and 34b of No. 4, respectively, to protrude upward, and are opposed to the magnetic pole portions 36a, which are one ends of the iron cores 36, respectively.

Further, the yoke 37 has a two-pronged upright piece 37c provided on the other end thereof that is fitted into a fitting hole provided in the base portion 35 to protrude upward, and the iron core 36 is attached to the upright piece 37c. The other end 36b is fixed by caulking, welding, or the like.

The coil terminal 39.39 is attached to the base portion 3/1.35.

They are inserted into the respective through holes 34c and 35b, with their lower ends protruding from the lower surface of the base 2, and the lead wires of the coil 38 are tied around and soldered to their upper ends.

Note that the stand 35 extending from the flange 33 is provided with a support shaft 35a that rotatably supports a card 40, which will be described later.

The contact drive card 40 consists of an annular frame 41,
This frame 41 includes a movable block portion 42 and arch-shaped connecting portions 43 extending from both ends of this movable block 42.
．． 4. =1, and a support portion 45 that is integrally connected to the movable block 42 at the connecting portions 43 and 44.

The movable block 12 stores and fixes the movable block 11 (pieces 47a and 47b) holding the permanent magnet 1G in its storage hole 42a.

The connecting portions 43, 44 have an arm portion 43a at their outer top.

4 and 1a are respectively provided, and the arm portion 43a holds the above-mentioned connection spring provisional 18, while the arm portion 44a holds the rear L.
It holds the holding part 51d of the letter-shaped drive piece 51.

Therefore, if the support hole 45a provided in the support part 45 is fitted into the support shaft 35a of the electromagnet device 30, the movable iron piece
17a is located between the magnetic pole part 36a of the iron core 36 and the upright piece 37a of the yoke 37, and faces each other so as to be able to approach and separate from them, while the movable iron piece 47! ] is located between the magnetic pole part 36a of the iron core 3G and the upright piece 37b of the yoke 37, and faces each other so as to be able to approach and separate.

The drive converter 50 converts the rotational motion of the card 40 into a reciprocating motion and slides the insulating slider 24, and includes an L-shaped drive piece 51 bent at a substantially right angle, a spring plate 52, and the base 2. It consists of a pair of positioning protrusions 8a and 8b and a support protrusion 8C.

The L-shaped drive piece 5I has a tip portion 5 on one bent side that can be engaged with the above-mentioned insulating slider 24 and that protrudes toward the center.
1a, and a straightly extending tip part st on the other bent side.
A clamping portion 51d having a diameter b is provided.

The temporary spring 52 is bent to form the positioning protrusion 8a.

When a planar shape that can be inserted between 8b and 8b is installed between the positioning protrusions 8a and 8b, the rear corner of the L-shaped drive piece 51 is constantly pressed and hinge-supported for rotation. It is something to do.

Therefore, after engaging the insulating slider 24 with the engaging part 51c of the L-shaped drive piece 51 and positioning its center part at the corner of the support protrusion 8c, the holding part 51d is held by the arm part 44a of the card 10. By holding and bending the spring temporary 52 and installing it between the positioning protrusions 8a and 8b, the L-shaped drive piece 51 is rotatably supported by the hinge. At this time, the tip portions 51a, 511+ of the L-shaped drive piece 51 are the protrusions 4b provided on the base 2.

2a, respectively.

The hot water portion 5.6 is located approximately at the vehicle surface I indicated by the two-dot chain line in FIG.
The base 2 is covered with a 7-shaped metal plate and is magnetically shielded, and the base 2 is sealed with a cover (not shown).

Next, the operation of the high frequency relay 1 having the above-described configuration will be explained.

FIG. 1 shows the neutral state, and the card 4G has returned to its original state in the non-excited state, and the movable iron piece 17 is moved by the magnetic force of the permanent magnet 46.
a is attracted to the magnetic pole part 36a of the iron core 36, and
The movable iron piece 47b is attracted to the upright piece 37b of the yoke 37 to form a magnetic circuit.

Then, when the movable contact piece 1.1 of the first contact mechanism part 1O is separated from the fixed contact terminal 11.12, and when the movable contact piece 16 is closed to the fixed contact terminal 12.13. , the t5T movable contact piece 23 of the second contact mechanism section 20 is closed to the fixed contact terminal 21.22.

In the returned state, the tip 51b of the letter 7-shaped driving seal piece 5I is in pressure contact with the protrusion 2a provided on the side wall of the base 2.

Now, the movable iron piece 47a repels the magnetic pole part 36a of the iron core 36, and the movable iron piece 47b moves against the upright piece 37 of the yoke 37.
When the coil 38 is excited to repel the magnetic pole part 36a, the movable iron piece 47a repels the magnetic pole part 36a, and the upright piece 3 of the yoke 37
7a, and the movable iron piece 47b moves toward the yoke 3.
It is repelled by the upright piece 37b of No. 7 and attracted to the magnetic pole portion 36a of the iron core 36.

Therefore, the card 40 rotates in the clockwise direction in FIG.
6a to form a magnetic circuit.

As the card 40 rotates, the insulating slider 15.
slides along the guide grooves 3a, 3b, and when the movable contact piece 14 closes the fixed contact terminal 11.12, the movable contact piece 16 separates from the fixed contact terminal 12.13.

On the other hand, as the card 40 rotates in the clockwise direction, the L-shaped drive piece 51 has the pinching part 51d held between its arms 44a.
rotates counterclockwise in FIG. 1 about the corner of the support beam $8c as a fulcrum, and the insulating slider 24 engaged with the engaging portion 51c slides along the guide groove 4a, and the movable contact piece 2
3 is separated from the fixed contact terminals 21 and 22.

Then, when the excitation is released, the card 40 maintains its operating state due to the magnetic force of the permanent magnet 46.

In the operating state, the tip end 51a of the L-shaped drive piece 51 is in pressure contact with the protrusion 4b provided on the partition wall 4.

Next, when the coil 38 is energized in the opposite direction to that described above, the card 40 rotates counterclockwise in FIG. 1 and returns to the restored state, and even when the excitation is removed, the card 40 remains in the restored state.

In this embodiment, when the movable contact pieces 14.16 and 23 do not close the fixed contact terminals 11, 12.13 and 21°22, the movable contact pieces +4°I6 and 23 close the grooves 5 and 6. They each contact the protrusions provided on the sides, providing high isolation.

Further, in this embodiment, the contact drive card 40 and the L-shaped drive piece 51 rotate parallel to the floor surface of the base 2, and the movable contact pieces I4, 16, and 23 rotate in parallel to the floor surface of the base 2. Since it reciprocates parallel to the other hand, there is an advantage that the device can be made thinner.

In addition, in the above-described embodiment, a case was shown in which the first contact mechanism section 10 and the second contact mechanism section 20 were provided independently, but this is not necessarily the case. For example, the first contact mechanism ( The fixed contact terminal 11 of the 2M section IO and the fixed contact terminal 21 of the second contact mechanism section 20 may be shared by one fixed contact terminal.

Moreover, it goes without saying that the present invention can be applied not only to high frequency relays but also to other relays.

Effects of the Invention As is clear from the above explanation, according to the present invention, the contact drive card that rotates parallel to the base surface or the I7-shaped drive piece that rotates parallel to the base surface , the first contact mechanism section and the second contact mechanism section arranged substantially perpendicularly on the base surface are opened and closed in conjunction with each other. Therefore, there is no need to take a driving distance to drive the driving member in a direction perpendicular to the base surface as in the conventional example.
This has the effect that the device can be made thinner.
