Abstract

PURPOSE:To form large locking force with low power, and to utilize the locking device for a push-button, etc. by arranging a magnet and an exciting coil shaping a magnetic field in the same direction as the magnet between a fixed yoke forming a magnetic path. CONSTITUTION:The yokes 22, 23 made of a ferromagnetic material are disposed at both sides of the magnet 21 magnetized to N and S poles, each exciting coil 24, 25 is mounted to the yokes 22, 23 through bobbins 26, 27, and coil terminal holding members 28, 29 are attached to the coils 24, 25. A member to be adsorbed 31 made of the ferromagnetic material is arranged at the outside, and adsorbing force is generated by the exciting force of the magnet 21 when the member 31 contacts with the yokes 22, 23. The adsorbing force by the magnet 21 is previously made smaller than returning force by a spring 32, the adsorbed member 31 is beforehand separated from the electromagnetic locking device when only the magnetic flux of the magnet 21 works, the adsorbed member 31 is adsorbed and held by the sum of magnetic flux at the time when the coils 24, 25 are excited and the magnetic flux of the magnet 21, and large locking force can be formed with low power.
