Abstract

PURPOSE:To enable a solenoid to be single-throw-worked or double-throw- worked, by inserting a pair of non-magnetic sleeves into a cylindrical coil bobbin, and by fitting magnetic pistons with the action controlled at the positions of the sleeves, into the respective sleeves. CONSTITUTION:When a piston 3a is resistant to its exciting force in a state that current is conducted to a coil 16, and is forcibly moved to the left by an external force, then another piston 3b which is excited to be confronted with is also moved to the left in the same manner, and the state of a third position can be set. If the piston 3b is moved to the right, the state of a fourth position can be set. When the electrical conduction of the coil 16 is stopped, then the pistons 3a, 3b are non-excited, and the respective pistons 3a, 3b can be freely moved by an external force. In spite of the electromagnetic solenoid of single composition in this manner, the single-throw or double-throw motion and forcible movement by the external force of the solenoid can be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electromagnetic side m-device, and more specifically to an electromagnetic control 11Vt device capable of unidirectional or bidirectional operation.

[Prior Art] As a driving source for linearly moving a movable object, there are a fluid pressure plunger and an ff1ta plunger (solenoid plunger). The former is used to compress fluid and transmit pressure by a combination of cylinders, just like a piston.
Mechanically, there are types in which the plunger moves in one direction and types in which the plunger moves in both directions. However, since this fluid pressure plunger uses compressed air, water, or oil, it has a disadvantage that it is structurally complex and difficult to miniaturize.

For example, as described in the ``Latest Audio Encyclopedia'' published by Radio Gijutsusha, an electromagnetic plunger has a brass cylinder with a coil wound around the core, the outside of which is surrounded by a soft iron yoke, and a soft iron round movable iron core. It is inserted from one end, and although there are some structural differences from those for DC or AC use, the iron core is drawn into the cylinder the moment the coil is energized, and it is small, lightweight, and has a pressurizing mechanism. It has the advantage that it is not necessary.

[Problems to be Solved by the Invention] However, in the conventional Ml & Plunger, the plunger operates only in one direction, and cannot operate the plunger in both directions.The only way to operate the plunger is to use a cut switch and two electromagnetic plungers. Is there a single unit without mechanical operation? 1fl
It was not possible to operate the solenoid unidirectionally or bidirectionally using external force.

It is an object of the present invention to eliminate the above-mentioned drawbacks and provide an electromagnetic control device that is a single-configuration electromagnetic solenoid but is capable of single or bidirectional operation of the solenoid and forcible movement by external force. be.

[Means for Solving the Problems] The above object is to provide a pair of non-magnetic sleeves that are installed in a cylindrical coil bobbin and are movable in the longitudinal direction of the bobbin; This is achieved by comprising a magnetic piston whose motion is regulated at the position of the sleeve.

[Function] The electromagnetic control device of the present invention has a piston fitted into a non-magnetic sleeve which is inserted into a cylindrical coil bobbin and whose movable range is regulated, and whose position is changed within the movable range. By applying current to the coil bobbin and applying an external force, the piston can be moved in both directions individually or simultaneously, and by fixing the coil bobbin or one piston, it is possible to move the piston in one direction. It is possible to carry out extensive control.

As shown in FIGS. 1 and 3 (a+, +b), the coil bobbin 1 has a pair of latches at constant dimensions from both ends on the inner wall 13 of a cylindrical winding core 12 with flanges 15 formed at both ends. It has a structure in which a coil 16 is wound around a bobbin 11 with protrusions 14 and 14 projecting therefrom.

As shown in FIGS. 1 to 3 (Ta, Yama), the non-magnetic sleeve 2 has a through hole 22 in the center with a size that is approximately 1/2 the length of the bobbin 11 and allows it to be inserted and slid onto the bobbin. established,
A non-magnetic cylindrical body 21 made of brass or the like, in which the locking protrusion 14 protrudes into the outer surface, and a control groove 23 for regulating the amount of movement within the bobbin and a narrow air escape groove 24 are carved along the entire length. It consists of

As shown in FIGS. 1 to 3 (ω, (b)), the magnetic piston 3 is attached to one end of a rod 31 having a size that allows it to be firmly fitted into the through hole 22 of the sleeve 2 by shrink fitting, adhesive, etc. It is made of magnetic material such as iron, and has a collar 32 with a diameter the same as or slightly smaller than the outer diameter of the sleeve 2, and a hole 33 that can form a universal joint B by attaching a ball joint 4, which will be described later, to the other end. It is configured.

As shown in FIG. 1, the ball joint 4 has a ball 4 at one end of the shaft rod 41.

Click the ball joint 4 into the hole 33 until it enters the control groove 23, and then insert the ball joint 4 with its spherical body 42 side into the hole 33, or after insertion, swage the edge of the hole and insert the ball joint 4 against the axis of the piston 3. The universal joint B is formed by allowing the axis of the shaft rod 41 of No. 4 to bend up and down and forward and backward.

The electromagnetic control device P of the present invention is constructed as described above, and the operation mode of this control device will be explained below. As shown in FIG. 3(a), the coil bobbin 1 is fixed, and the two pistons 3a and 3b are placed in a position where r432 and 32 are separated, so that the locking protrusion 14 and the control groove 2

When DC current is applied to the pistons 3a and 3b, the pistons 3a and 3b are excited and attract each other, and as shown in FIG. Each piston faces each other and pulls the object connected to the universal joint B inwardly to control it to the second position.

If the piston 3a is forcibly moved to the left by an external force against the excitation force of the coil 16 while the coil 16 is energized, the other piston 3b, which is energized in tandem, will similarly move to the left, as shown in Fig. 4. The third position can be achieved as shown in FIG. Also, if the piston 3b is moved to the right, the
