Description

ANTI-STATIC ELECTRICITY UNIT}

Generally, the human body can be electrostatically charged by electrostatic induction due to various situation causes. The main reason is that the exchange of electrons on the surface of two materials to be contacted or the difference in dielectric constant, temperature effect, and piezoelectric effect between two materials causes static electricity .

At this time, when the object having a relatively low resistivity is contacted, the charged electric charge is discharged to the human body, and the human body receives a surprise shock according to the magnitude of the discharged electric current.

Therefore, the present invention prevents electrostatic shock by allowing the static electricity generated from the human body to flow to the ground through the static self-extinguishing mechanism attached to the opening / closing switch portion of the elevator, the handle of the car door or the handle portion of the door. To an electrostatic self-extinguishing mechanism

In the past, there were various kinds of static eliminators, but the main type was a rod type which is attached to a key ring separately or a portable type which is directly attached to a key.

The conventional electrostatic extinction mechanisms as described above are always in contact with each other. However, since the electrostatic discharge device hanging on the key ring must be brought into contact with the place to be discharged every time the device is used, There is a problem that static electricity can not be prevented because many people can not use the device because of contact with other people.

In order to solve the above-described problems, the present invention provides a touch panel that can be easily contacted by a user, a resistor and a diode are connected in series by soldering, and one side of the diode is soldered to a metal plate having an elastic piece It is an object of the present invention to provide a static electricity self-extinguishing mechanism that is fixedly installed in a place where the metal frequently contacts, thereby preventing a shock caused by static electricity, which is occasionally generated by a human body.

As described above, the static electricity generated from the human body in various situations of everyday life is safely discharged to the attached object and the grounded ground through the electrostatic self-extinguishing mechanism of the present invention, so that the shock caused by the static electricity does not occur even when the human body comes into contact with the attached object It is effective to prevent.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view of the present invention, FIG. 2 is an assembled cross-sectional view of the present invention, and FIG. 3 is an electrical block diagram of the electrostatic self-extinguishing mechanism of the present invention.

1 and 2, the electrostatic self-extinguishing mechanism 1 includes a diode 21 and a resistor 22 at the upper portion of a metal disc 10 having a bottom groove 11 formed therein. And one side of the diode (21) is soldered to be attached to the metal substrate (20);

A dome cover 30 having a touch plate 31 is attached and fixed to the upper portion of the metal disc 10 and the metal substrate 20. The resistor 22 is attached to the bottom of the touch plate 31, One end of which is fixed by soldering;

An elastic piece 12 is attached and fixed to the inside of the groove 11 formed at the bottom of the metal disc 10;

A double-sided tape 40 having a release paper 41 is attached to the periphery of the bottom of the metal disk 10.

Reference numeral 100 denotes an object to be attached, 101 denotes an elevator, and 102 denotes an elevator opening / closing switch.

The electrostatic discharge strip 1 thus formed has a touch plate 31, a resistor 22, and a diode 21. The metal plate 20, the metal plate 10, and the resilient piece 12 are attached so as to form a serial form.

In other words, as shown in an electrical block diagram of the electrostatic self-extinguishing mechanism of FIG. 3, the conductive plate is brought from the touch plate 31 to the attached object 100.

The dome-shaped cover 30 is attached and fixed to the metal disc 10 so as to protect the diode 21 and the resistor 22 formed on the metal substrate 20, So that the touch plate 31 is positioned.

A groove 11 is formed at the bottom of the metal disk 10 to adhere the elastic piece 12 to the metal disk 10 to the inside of the groove 11 so that the electrostatic self- So that the elastic piece 12 can be easily brought into contact with the attachment object 100 when the elastic piece 12 is installed on the attachment object 100.

The electrostatic self-extinguishing mechanism 1 is attached to an object 100 to be used. For example, the electrostatic self-extinguishing mechanism 1 is attached to an elevator opening / closing switch 102, an automobile door handle, The peeling paper 41 formed on the backing layer 40 is peeled off and then attached using the double-faced tape 40.

The double-sided tape 40 formed by attaching the above-described double-sided tape 40 is intended to make it easy for anyone to easily purchase and install it in a necessary place so as to prevent the shock caused by the static electricity at all times.

4 shows an example of the use of the present invention. The electrostatic self-extinguishing mechanism 1 is attached to the opening / closing switch part 102 formed on the side of the elevator 101, 31) to discharge the static electricity in the human body first and then press the open / close switch to prevent the shock caused by the static electricity.

As another example, it is also possible to use the touch panel 31 formed in the static self-extinguishing mechanism 1 before touching the door of the automobile door, Thereby preventing shock caused by static electricity.
