Claims

[Scope of utility model registration request]

(1) a fixed iron core, an insulated plastic coil spring whose one end fits into the fixed iron core and sets an electric current, and a plunger which is attached within the other end of the coil spring and faces the fixed iron core; Loosely fit the coil spring into the
a rigid excitation coil that attracts the plunger to the fixed iron core against the spring force of the coil spring by applying the exciting current; and a rigid excitation coil that is disposed outside the excitation coil to form an outer magnetic path of the excitation coil. A plunger type electromagnet device equipped with a yoke.

(2) the yoke consists of a flat plate-shaped yoke piece and a U-shaped bent yoke piece which is caulked and fixed to the flat plate-shaped yoke piece to form a frame shape; the fixed iron core is fixed to the center part of the flat plate-shaped yoke piece;
The U-shaped bent yoke piece has an insertion hole through which the coil spring is inserted in the opposite part of the fixed iron core, and a notch is formed on the edge of the insertion hole, and the coil spring is inserted into the plunger side. The end side surface has a protrusion that can pass through the notch, and the coil spring is passed through the insertion hole, and the protrusion is passed through the notch and rotated, so that the fixed core and the insertion hole are compressed. A plunger type electromagnet device according to claim (1), which is supported between a hole edge and a hole edge of the plunger type electromagnet device.
