A coil 5 is wound around a letter-shaped iron core 3.

Further, on the upper surface of both ends of the support frame 2, coil lead-out terminals 6, 6 whose tips are bent into an L-shape extend outward, and the lead wire ends of the coil 5 are connected to the coil lead-out terminals 6, 6. It is rolled up.

Furthermore, the outer ends of the magnetic poles 4, 4 are provided so as to slightly bulge out from the end surface of the support frame 2, and engagement protrusions 7, 7 are provided on both side surfaces, respectively.

The rule is that the contact block is provided with a recess 9 in which the coil block 1 can be housed, and movable contact terminals 10, 10, 11, 11 whose upper ends protrude at the center of both upper surfaces, and upper end portions at both ends. A coil terminal 1 in which fixed contact terminals 12 and 12 with fixed contacts protruding from the front and back sides are simultaneously molded, and the upper surfaces of both end walls are cut out to expose the upper end portions 14, 14.
3.13 are molded at the same time, and the coil terminal 13,
The upper end portions 14, 14 of 13 and the L-shaped tips of the coil lead-out terminals 6, 6 are formed to match.

Further, the downwardly protruding ends of the movable contact terminals 10, 10, 11, 11, fixed contact terminals 12, 12, and coil terminals 13, 130 are aligned in two rows on both sides.9 Furthermore, the inner upper edge of the end surface of the contact block 8 are formed with recesses 15, 15 for receiving the outer ends of the magnetic poles 4, 4, and the engaging protrusions 7, 7 are formed on the inner surfaces corresponding to the side surfaces on which the engaging protrusions 7, 7 are provided. The engaging recesses 16.16 are provided oppositely.

17.17 is a first contact spring whose base part is bent into an L-shape and is fixed inside the movable contact terminal 10.10 in the central part;
Reference numeral 18.18 denotes a second contact spring whose base is bent into an L-shape, and which is fixed to the outside of the movable contact terminals ii and i1 on both sides of the movable contact terminal 10.10, and has a movable spring at each end. The contacts are fixedly installed, and the fixed contact terminals 1 near both ends are
It is provided so as to be able to contact the inner and outer fixed contacts of 1 and 11, respectively.

Reference numeral 19 denotes a separator in which notches 20, 20 are formed corresponding to the magnetic poles 4, 4 protruding from the coil block 1, and a shaft 21 is implanted in the center.

U is an armature block, a pair of armatures 2
3.23 are arranged parallel to each other, and a bearing piece 24 having a shaft hole 25 drilled in the center through which the shaft 21 is inserted is integrated. , and protrude outward in a direction perpendicular to the longitudinal direction of the armature 23.23, and the first contact spring 17.17 and the second contact spring 18 are provided at the protruding end in the perpendicular direction.
A card part 26,26 with actuating projections 27, 27 located between 18 is integrated.

Furthermore, the protruding ends on both sides of the armatures 23, 23 are provided to play with the magnetic poles 4, 4.

28. 28 is a concave portion 29, 29 sandwiching the bearing piece 24.
A permanent magnet 30 housed in is a cover having a receiving portion 31 for the shaft 21 formed on the inner wall of the upper surface thereof, and its lower edge is brought into contact with and fixed to the stepped portion 32 of the contact block.

Then, the coil block 1 is fitted into the recess 9 of the contact block, and the first and second contact springs 17, 1γ, is, i
By mounting a contact opening/closing member group consisting of s, separator 19, and armature block U and capping with a cover 30, a polarized relay can be easily assembled by simply stacking them one after another from one direction.

When the coil 5 of the relay just assembled is energized, the armature block 22 is rotated as shown in FIG. The movable contacts of the first contact springs 17a, 17d and the second contact springs 18b, 18c are opened, and the first contact springs 1γb, 17c and the second contact springs 1.8a are opened.
, 18d are closed, and by excitation in the opposite direction, a reverse operation can be obtained, and a four-transfer contact configuration can be realized.

Furthermore, even after the excitation to the coil 5 is cut off, the armature block υ, which has been rotated in one direction, is attracted to the magnetic poles 4, 4 by the magnetic force of the permanent magnets 28, 28, so that it maintains its position during operation. .

In other words, it is self-maintained.

According to the polarized relay of the present invention configured as described above, a) The device can be made compact.

b. Vibration resistance can be improved.

C: Good sensitivity, high speed operation, and high sensitivity.

d It can have a self-holding function.

It is possible to achieve a relay having a four-transfer contact configuration that exhibits remarkable effects such as the following.
