Fixed contact Z (a is attached to the upper surface of the short fixed terminal plate 22&, and fixed contact 23b is attached to the lower surface of the long fixed terminal plate 22b. Both fixed terminal plates 4a, 6 fixed contacts are formed. The other end of the movable contact spring 2 is bent in a direction perpendicular to the terminal plate, forming fixed contact terminals ya and pb.A movable contact terminal 2 is attached to one end of the movable contact spring 2. .

Movable contact springs 2] are attached to both upper and lower surfaces of the free end side. The movable contact spring 21 is bent stepwise from the surface 21a to which the movable contact is attached to the terminal fixing portion 21b. The bent part 21C of the movable contact spring 2, which is bent in the shape of a central step, is cut out, and the edge provided along the longitudinal direction from this notch I toward the movable contact part is a card of the movable insulator 3! It is designed to be held in the groove at the tip.

The box-shaped base 4 is made of an insulating material, has an open top and one of its longitudinal ends, and is partitioned internally by a wall d made of an insulating material to form two spaces C2.

An insulating wall section is formed at the lower part of the wall termination section. An electromagnet block 1 is housed in the upper space, and a contact block 2 is housed in the lower space.

The movable contact of the movable contact spring 2, which is connected to and interlocks with the Mf Aero 5, moves in reverse from the fixed contact 23b, which was in contact with it before energization, toward the fixed contact 23a, and finally comes into contact with the fixed contact 23&. be done. That is, when the coil is not energized, the movable contact I and the fixed contact 23
b is closed, and in the energized state, the movable contact row and the fixed contact 23a
The gap begins to close. Further, the movable insulating wall portion formed on the movable insulating body 3 is moved up and down as the movable insulating body 3 swings at a position immediately in front of the outer wall surface of the fixed insulating wall portion. Therefore, the communication portion between the contact block storage space center and the communication space line is made as small as possible, and the insulation between the electromagnet block l and the contact block 2 is further improved.

As described above, in this relay, the inside of the base 4 is partitioned by a wall made of insulating material, and two spaces C143 are created.
The electromagnetic block 1 is housed in one space, and the contact block 2 is housed in the center of the other space, increasing the insulation between both blocks. In general, such a configuration can improve the insulation between the electromagnet block 1 and the contact block 2, but since there is a wall d between them, the movement of the amateur chairo 5 cannot be transmitted to the contact block 2 by the movable insulator 3. , it becomes difficult to open and close the contacts smoothly. If a movable insulator for smooth opening and closing of the contact is to be provided, the insulator for the wall must be removed, and the insulation between the electromagnet block 1 and the contact block 2 will be impaired. In this relay, a movable insulator 3 is connected to an electromagnet block 1 and a contact block 2.
It has a card & that is fixed to the armature 65 in a space 6 that communicates with the terminal ends of both storage spaces, and extends along this wall d around the terminal end of the wall in the contact block storage space C. In the contact block storage space C, the wall 41
Cards stretching along! Therefore, the optimum driving point of the movable contact spring 21 can be easily selected.
It becomes possible to smoothly close the contacts. or,
Furthermore, since this movable insulator 3 goes around the end of the wall d and connects the armature 65 and the contact block 2, the insulation between the electromagnetic block 1 and the contact block 2 is removed without removing the wall 41. without compromising sexuality,
This movable insulator 3 allows the movement of the armature 65 to be transmitted to the contact block 2, allowing the contacts to open and close smoothly.

The relay according to the present invention is not limited to the above embodiment.

〔Effect of the invention〕

In the present invention, as described above, the inside of the base is partitioned by walls made of insulating material to form a plurality of spaces, an electromagnetic block is housed in one of the spaces, and a contact block is housed in the other space, In addition, the movable insulator is fixed to the armature in a space that communicates with the ends of the two spaces in which both blocks are housed, and a card that extends around the end of the wall and extends along this wall in the contact block storage space. Because of its features, it is possible to ensure insulation between the electromagnet block and the contact block without increasing the dimensions or adding separate parts, and it is small and has a small number of parts.
