Description

[Detailed Description of the Invention] The present invention relates to a plunger remade, and more particularly to a plunger remade that can maintain a suction state even after the solenoid is de-energized.

The basic structure of the conventional plunger solenoid is that it has an iron core inside and a coil wound around the outside.By controlling the current flow to this coil, the iron core moves in the required manner, allowing various operations to be performed. is being carried out.

In addition, in the conventional plunger remade, in order to prevent an increase in coil resistance due to heat generation, measures have been taken to reduce heat generation and increase the kinetic force of the iron core.

However, in the conventional plunger solenoid described above, it is necessary to keep current flowing through the coil while the iron core is being attracted, which has the drawback of increasing power consumption and generating heat.

Recently, there are devices that can mechanically lock the iron core in a state where it remains attracted even if the current is turned off once the iron core has been attracted, but the mechanical configuration is complicated. There was a drawback.

The purpose of this invention is to eliminate the above-mentioned drawbacks of the conventional technology, and by using a push-button switch mechanism, the plunger can be locked even when the current is turned off while the iron core remains attracted with a simple structure. It also provides a solenoid.

Hereinafter, the present invention will be described according to an embodiment illustrated in the accompanying drawings.

Fig. 1 is a perspective view of essential parts of a plunger solenoid in one embodiment of the present invention, Fig. 2 is a sectional side view of the solenoid, and Fig. 3 is a plan view of the same. A frame that forms the outer wall of the plunger solenoid, and has a coil, iron core, etc. described below inside.

This frame 1 has an upper surface and a lower surface that constitute the outer circumferential wall of the solenoid, and a boss 1b that protrudes from the outer surface and has a head is fixed to one outer surface, and the outer surface of the same frame 1 to which the boss 1b is fixed is The cut-and-raised portion 1d is bent outward, and an elongated hole 1c (the hole is also formed on the other side) having a long diameter portion in the advancing and retreating direction of the iron core, which will be described later.

Incidentally, reference numeral 1a designates a stopper on the front surface of the solenoid formed by the frame 1, which restricts the iron core from entering into the coil.

A lock plate 2 is placed on the outer surface of the frame 1, and both ends of the lock plate 2 abut against the recess of the vertical portion 21 bent on the lock plate 2 and the recess of the cut-out portion 1d of the frame 1. This is accomplished by a spring 3 inserted into the body of the boss 1b, and a lock plate 2 rotatably pivoted to the boss 1b.

To explain the shape of this lock plate 2, as mentioned above, this lock plate 2 has a vertical part 21 formed therein, and also has a body part 2 whose rear end side is to be pivotally connected to the boss part 1b.
2, a triangular protrusion 23 and a neck 24 are arranged side by side on the front end side of the body 22, and a sickle-shaped head 25 is formed through the neck 24. An art dealer protrusion 26 is formed from the inner midsection.

Further, on the front end side of the body portion 22, a first front end portion 221 and a second front end portion 222 are formed so as to come into contact with a pin 4, which will be described later, with the triangular projection 23 and neck portion 24 remaining.

Lock 2, which forms the above structure, looks like this, with arrows A and B.
(horizontal direction), C, and D (vertical direction), and is normally biased in direction B by the force of the spring 3.

Here, the cut-out portion 1d of the frame 1 normally comes into contact with the side surface of the lock plate 2, and also functions as a stopper that restricts the range in which the lock plate 2 is rotated in the direction B by the force of the spring 3.

Next, to explain the iron core of the plunger solenoid, this iron core is indicated by 5, and a pin 4 with both ends penetrating is formed in the hole 1c formed on the upper and lower surfaces of the frame 1, and an arrow mark inside the coil 6 is formed. It is urged by a spring 7 in the E direction.

Furthermore, power supply terminals 6a and 6b are provided on the outer surface of the frame 1 to supply power to the coil 6.

The plunger solenoid in one embodiment of the present invention is constructed as described above, and its specific operation will now be described.

First, when a predetermined power is applied to the power supply terminals 6a and 6b, a current flows through the coil 6 and the iron core 5 moves in the direction of arrow F against the force of the spring 7.

As the iron core 5 moves, the pin 4 comes into contact with the outer surface of the sickle-shaped head 25 from the state shown in FIG.
This sickle-blade-shaped head 25 is moved by arrow A against the force of spring 3.
rotate in the direction.

Furthermore, as the iron core 5 moves, the pin 4 moves until it comes into contact with the first front end 221 of the body 22 of the lock plate 2 and is locked, as shown in FIG.

At this time, when the power to the power supply terminals 6a and 6b is cut off, the iron core 5 tries to move in the direction of arrow E due to the spring 7, but as shown in FIG. The iron core 5 is held against the elasticity of the spring 7 because it abuts and is locked against the inner surface of the plunger 25 and the art dealer protrusion 26, and the plunger solenoid is kept in a locked state even though the energized state is released. It will be done.

Next, the case of releasing the locked state will be explained.

First, when power is supplied to the power supply terminals 6a and 6b again,
The iron core 5 is sucked again.

Accordingly, the pin 4 comes into contact with the second front end 222 formed between the neck 24 and the triangular protrusion 23 and is locked therein.

At this time, when the power to the power supply terminals 6a and 6b is cut off, the iron core 5 is moved in the direction of arrow E by the spring 7, and the pin 4 is moved in the direction of arrow E, as shown in FIG. Enter the bottom surface of the art dealer protrusion 26 as shown in the figure, push up the lock plate 2 in the direction of the arrow, and then release the spring 7.
With this, the iron core 5 and the iron core 5 are returned to the state shown in FIG. 4 (2).

After the pin 4 returns, the lock plate 2 is also rotated in the direction of arrow C by the spring 3, returning to the state shown in FIG.

Therefore, according to the present invention, the locked state can be secured by turning the power on and then shutting off, and the unlocked state can be secured by turning the power on and then shutting off. It is a preferable solenoid as it has almost no problems.
