Embodiment Construction

[0020] Figure 1 ~ Figure 3 It is a structural diagram of the present invention, figure 1 main view, figure 2 From figure 1 A partial perspective view of the side view, image 3 It is a cross-sectional view viewed from the side. In each figure, 1 is a movable shaft provided with threads at both ends, 2 is a stator formed in a cylindrical shape, and one end of the movable shaft penetrates through the hole of the stator 2, and 3 is fixed to the movable shaft. The movable element on 1 is inserted between the movable element 3 and the stator 2 so that the movable element and the stator are always separated, and the blocking spring 4 is pressed. And the breaking spring 4, the excitation coil 6 is wound in the frame. 7 is a frame, one end is formed in a U-shape with one end closed, and the hole 7a is provided through the center of the one end closed, and one end of the movable shaft 1 penetrates the hole 7a.

Abstract

Magnetic force deteriorates in a shorter time due to fastening pressure applied to a permanent magnet and positional shift of the permanent magnet due to vibration at the time of assembling an electromagnetic device having the permanent magnet attached thereto. A frame-shaped magnet holder composed of a nonmagnetic material is provided.  The magnet holder is formed with a thickness equivalent to or slightly more than that of the permanent magnet, and is provided with a fixing arm, which is connected to one edge of the frame-like body along the center line thereof and has a fixing hole.  Furthermore, supporting pieces are arranged to face the fixing arm with a hollow section therebetween, such that the supporting piece ends on one side are connected to the edge of the frame-like body and that the other ends are in the opened state.  On the surface where each supporting piece and the frame-like edge face each other, a space where the permanent magnet or a magnetic short-circuiting piece is fitted and inserted is provided.

Description

technical field [0001] The present invention relates to an electromagnet device, and more particularly to a magnet holder for holding a permanent magnet and a magnetic short circuit mounted on the electromagnet. Background technique [0002] A general switch has a pair of electrodes consisting of a fixed electrode and a movable electrode inside, and the opening and closing control of the switch is implemented through the control of the electromagnet device. The electromagnet device consists of an excitation coil, iron core, frame, etc., and closes the movable element to the fixed side by the magnetic attraction force generated when the excitation current flows through the excitation coil. As a latching method for maintaining the closed state, continuous excitation (Japanese: constant excitation), mechanical latch, and magnetic latch are known. [0003] In the prior art, in order to keep the closed state, since it is necessary to constantly and continuously energize the exci...
