Claims

[Claims for Utility Model Registration] 1. In a solenoid that guides a movable iron core 4 over a predetermined distance using a tube assembly 5 in which magnetic bodies 7, 3 and non-magnetic bodies 6 are connected by welding, both magnetic bodies 7, 3 and The non-magnetic body 6 has a butt-welded structure, and the inner diameter of the non-magnetic body 6 is larger than the movable core guide diameter of the magnetic bodies 7 and 3, and is also large enough so that the movement of the movable core 4 is not obstructed by the back bead 12. Solenoid. 2 In a solenoid in which the movable core 4 is guided through a predetermined distance by a tube assembly 5 in which magnetic bodies 7, 3 and a non-magnetic body 6 are connected by welding, one end of the non-magnetic body 6 has a butt-welded structure with the magnetic body 7. The inner diameter of the non-magnetic body 6 is larger than the movable core guide diameter of the magnetic bodies 7 and 3, and the size is such that the movement of the movable core 4 is not obstructed by the back bead 12. A solenoid characterized in that its surface is fitted into a cylindrical body part 9 protruding from the end face of the remaining magnetic body 3, and the outer periphery butt portions are welded. 3. Claim 1, wherein the movable core 4 is provided with a protrusion 11 extending along the inner peripheral surface of the non-magnetic body 6, and the axial length of the non-magnetic body 6 is selected to be a length that allows the movable core 4 to move a predetermined distance. Or the solenoid described in 2. 4. The solenoid according to claim 1, 2 or 3, wherein one of the magnetic bodies 3 connected to the non-magnetic body 6 is a fixed magnetic pole.
