Abstract

PURPOSE:To make the core proper to mass production while improving performance by forming one part or the whole of the core by a body manufactured by molding the laminate of magnetic iron plates through drawing working. CONSTITUTION:The solenoid consists of a columnar fixed core 1, a movable core 2 and a cylindrical vessel type yoke 3. The yoke 3 is divided into two sections in the axial direction, the fixed core 1 is tightly mounted into the central through-hole 5a of one yoke section 3a mechanically and magnetically, and the movable core 2 is penetrated into the central through-hole 5b of the other yoke section 3b. The yoke section 3a is formed in an approximately cylindrical vessel shape, one end surface thereof is opened and the other end surface thereof has the core through-port 5a. When manufacturing the yoke 3a, the necessary number of the flat magnetic iron plates are laminated, and molded in a vessel type through deep-drawing working by a press, and contacting surfaces with the through-hole 5a and the other yoke section 3b are cut and worked. The other yoke section 3b can also be manufactured in the completely same manner as the yoke section 3a.
