Abstract

PURPOSE:To make a relay thin by disposing a permanent magnet and an armature block in lamination within the height of a coil block and on the side of the coil block. CONSTITUTION:Container parts 31, 32 are formed on both sides of an insulation wall 25 of a body 1, and a coil block 2 is disposed at the container part 31, and end parts 28a of iron cores 28 protrude from both end parts of the insulation wall 25 to be positioned on the side of the other container part 32. A permanent magnet 3 is disposed between end part magnetic poles of the iron cores 28 on the container part 32 side. An armature block 4 is disposed over the permanent magnet 3. The thickness of the permanent magnet 3 is formed thinner than the thickness of the end parts 28a of the iron cores 28, and a high density disposition is achieved by using a plate thickness of the iron core 28 as a dead space. The height of vertical disposition of the permanent magnet 3 and the armature block 4 is set lower than the height of the coil block 2 disposed on the side through the insulation wall 25.

Further, as shown in FIG. 2(d), the thickness of the permanent magnet 3 is formed to be thinner than the thickness of the end portion 28a of the iron core 28,
The thick part of the iron core 28, which would normally be a dead space, is used to achieve a high density arrangement. Further, the height at which the permanent magnet 3 and the armature block 4 are arranged in the vertical direction is lower than the height of the coil block 2 which is arranged laterally with the insulating wall 25 interposed therebetween. By arranging each block in this manner, it is possible to reduce the size of the relay due to the high-density arrangement of each member, and since it is possible to assemble the relay by a stacking method, automation of production equipment is facilitated. Furthermore, since the armature block 4 is arranged on the side of the coil block 2, a thin seesaw type relay can be obtained, and since the contacts 36.15 and the coil 27 are separated, this is especially true in this embodiment. In the case of a single-pole configuration as in the example, a large insulation distance can be provided. Further, the insulation distance between the coil terminals 19 and the terminal plates 12 can be increased.

4a is attracted to one end 28a of the iron core 28, and one contact point 4a is in contact with the other end 28a. When the other coil 27 is excited, the electromagnetic force of the coil 27 causes the armature 3 to
The other end 34a of the iron core 28 is attracted to the other end 28a of the iron core 28, and the other contacts 36.15 and 36.15 are connected in contact.
