に使用されている。Conventional configurations and their problems In recent years, record players, video tape recorders, cassette tape recorders, etc.
Motors and electromagnetic solenoids are commonly used as means for converting electrical signals into mechanical systems because they are easy and inexpensive.
その従来の電磁ソレノイドの構成について以下
述べる。 The configuration of the conventional electromagnetic solenoid will be described below.

鉄心1の動きを止める固定物である。 Figure 1 shows a cross section of a conventional electromagnetic solenoid, where 1 is an iron core, 2 is a coil, 3 is a yoke, and 4 is a sectional view of a conventional electromagnetic solenoid.
5 is a spring for returning the iron core 1; 6 is a connecting piece connected to a driven object (not shown) driven by an electromagnetic solenoid; and 7 is a fixed object that stops the movement of the iron core 1. It is.

撃音が発生する。又振動も同時に発生し、この衝
撃音、及び振動が有害になり、機器の品位を落と
すという問題がある。 At the moment when current flows through coil 2, iron core 1 moves to arrow A.
, and the connecting piece 6 is also pulled in the direction of arrow B at the same time. Electrical-mechanical conversion is performed in this manner, but since both the iron core 1 and the iron core receiver 4 are made of iron-based metal, an impact noise is generated at the time of a collision. In addition, vibrations are also generated, and this impact noise and vibrations become harmful and degrade the quality of the equipment.

本考案は、その有害な衝撃音及び振動をほとん

提供することを目的とする。Purpose of the invention The purpose of the invention is to provide an electromagnetic solenoid that can almost completely eliminate harmful impact noise and vibration.

できるものである。Structure of the invention The invention is an electromagnetic solenoid in which a pipe is loosely fitted to the outside of a movable iron core through a viscous material such as silicone oil.The viscous material reduces the moving speed of the iron core and reduces impact noise and vibration. It can be removed.
実施例の説明
本考案の一実施例を第2図に示すが、第1図と
同じ機能をもつ部分には同じ記号を付した説明を
省略する。DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention is shown in FIG. 2, in which parts having the same functions as those in FIG. 1 are given the same symbols and explanations are omitted.
本実施例の特徴は、鉄心1に遊嵌したパイプ9

イル等の粘性体を塗布する。又バネ10はたえ
ず、パイプ9を下方に押しつけるが、そのバネの
力はバネ5のバネの力より弱く設定されている。 The feature of this embodiment is that the pipe 9 is loosely fitted into the iron core 1.
It is in. A reservoir groove 8 for a viscous substance such as silicone oil is provided in a part of the iron core 1, and an appropriate clearance is provided between the iron core 1 and the pipe 9, and a viscous substance such as silicone oil is applied between them. Also, the spring 10 constantly presses the pipe 9 downward, but its spring force is set to be weaker than the spring force of the spring 5.
コイル2に電流が流れると、鉄心1は矢印Aの
方向へ強く吸引される。しかしパイプ9との間に

引速度はゆるやかになる。その結果、鉄心受け4
との衝撃が緩和されることになり、衝撃音及び振
動は非常に小さなものとなる。 When current flows through the coil 2, the iron core 1 is strongly attracted in the direction of arrow A. However, the suction force is damped by the viscous resistance of a viscous material such as silicone oil between the pipe 9 and the pipe 9. The higher the suction speed of the iron core 1, the greater the viscous resistance, and the slower the suction speed of the iron core 1. As a result, the core receiver 4
This reduces impact noise and vibration, making impact noise and vibration extremely small.
次に電流が遮断されると、鉄心1はバネ5によ

鉄心1が固定物7に当る所まで来て止まると、今

ーク3に当るまで動く。 Next, when the current is interrupted, the iron core 1 quickly moves in the opposite direction of arrow A by the spring 5. At that time, the pipe 9 also moves in the same direction while compressing the spring 10.
When the iron core 1 reaches the point where it hits the fixed object 7 and stops, the pipe 9 is pushed by the spring 10 and slowly moves until it hits the yoke 3.

を実現できるものである。Effects of the invention The present invention loosely fits a pipe into a movable iron core, injects a viscous substance such as silicone oil between the iron core and the pipe, and presses the pipe toward the coil with a spring, thereby attaching the pipe to the coil. At the moment when electricity is applied, the iron core is gently attracted by the viscous resistance of the viscous body, preventing the generation of impact noise and vibration noise, and when the current is cut off, the iron core can be quickly returned to the specified position. It is possible to realize an electromagnetic solenoid.
