DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic relay, and its purpose is to provide a total electromagnetic appliance in which a group of connection terminals are collectively mounted on one surface, and to obtain a particularly thin electromagnetic relay in large numbers. To provide an electromagnetic relay which can effectively use the surface area of a mounting panel when two electromagnetic electrical appliances are arranged side by side, and which can ensure a stable fixed state of each component in the structure of the electromagnetic relay.

The electromagnetic relay of the present invention will be described below with reference to the drawings listed as examples. A is a coil block, and a drive card 3 drives movable contact plates 2a, 2b, 2c, and 2d in the axial direction of the electromagnetic coil 1. A coil frame 8 is formed in such a manner that a guide part 4 and a reversing part 7 for attaching a permanent magnet 5, an auxiliary fork 6, etc. are arranged therein, and a through hole 9 is provided through the inside of the coil frame 8.

A movable contact block BI is formed by attaching contacts 15a, 15b to one end of the movable contact plates 2a, 2b and connecting terminals 16a, 16b at the other end by an insulating support 17a, and one end of the movable contacts 2c, 2d. A movable contact block B2 is constituted by attaching contacts 15c and 15d to the terminals and connecting terminals 16c and 16d at the other end, which are integrated with an insulating support 17M, so that the insulating supports 17a and 17b can be combined. The engagement spring 18 allows the main yoke 14 to be accurately positioned and mounted on a magnetic path that intersects with the axial direction X of the main yoke 14 and serves as the fulcrum of the armature 10.

Incidentally, during this installation, the protrusions 8a and 8b provided on the coil frame 8 are sandwiched between the insulating support 17a and the main yoke 14.

In this installed state, the movable contact plates 2a, 2b and 2c, 2

Due to this reversal operation, the drive card 3 moves down the guide part 4 and brings the movable contact plates 2c and 2d into contact with the contacts 19a and 19b.
Push up the movable contact plates 2a and 2b to remove the contacts 15a and 15b.

By passing an excitation current in the opposite direction through the magnets c and 11d, the free end of the armature 10 is magnetized to the S pole, and the main yoke 1
4 and is attracted and held on the auxiliary yoke 6 side.

Due to this reversal operation, the drive card 3 moves and rises, and moves away from the movable contact plates 2a and 2b, and moves to the movable contact plates 2c and 2d.
push up. Thus, the contacts 15a and 15b come into contact with the contacts 19a and 19b due to the self-restoring force of the movable contact plates 2c and 2d, and the contacts 15c and 15d are opened from the contacts 19a and 19b. As described above, according to the electromagnetic relay of the present invention,

Similarly, the movable contact block B is provided on the magnetic path of the flat main yoke 14 by extending in the same direction as the axial direction.
1, B2 and the fixed contact block C are arranged in parallel, and all the connection terminals are supported as one by the support 25 combined with the case 31, the support 25
The dimensions in one direction when viewed from above are compressed, resulting in a thin electromagnetic relay.

It is suitable for the case where a large number of electromagnetic relays are arranged side by side and installed on a control panel, and each block B1, B
2 and C are attached to the main yoke 14 and supported by the support body 25. Therefore, the position between the movable contact blocks B1, B2 and the fixed contact block C varies with respect to the movement of each connection terminal.
