この発明は静電気の放電に伴って生体が受ける衝撃を防
止する電撃防止素子に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric shock prevention element that prevents shocks received by a living body due to discharge of static electricity.
床や履物などの絶縁性が高い場合、着衣などの摩擦など
によって静電気が発生し、生体において帯電現象が起る

の放電によっても同様のｔＩＩを受ける。When floors and footwear have high insulating properties, static electricity is generated due to friction with clothing, etc., and a charging phenomenon occurs in living organisms. The electrostatic capacitance of a living body varies greatly depending on the conditions of the floor and objects on the side, but it is approximately 100 pF.When the Teiden solder level exceeds 1KV, a discharge phenomenon from the living body is observed. When the electric shock is discharged, the living body will feel the electric shock.Normally, the body is not conscious of its presence, and it is very surprising to receive an electric shock, and the electric shock causes pain. It also causes great discomfort.A similar tII is also caused by discharge from an IE object.
し九がって、静電気を何らのショックも受けないで放電
し°Ｃやる必要がある。Therefore, it is necessary to discharge static electricity without receiving any shock.

る。However, with such a structure, the discharge potential changes depending on the distance between the discharge gaps, so there is a problem that the discharge potential cannot be easily controlled. Further, the discharge gap is as small as several tens of micrometers, and if a short circuit occurs between the discharge gaps, electric shock may occur due to the discharge. The shock at that time will make you feel even more uncomfortable than when you use an electric shock prevention device.

体からの静電差を放電する放電側電極となる。In the figure, a resistor C, 1 is housed in an insulating tube 2, and a conductive elastic material 5.4 such as conductive rubber is connected to the end of the insulating tube 2. A conductive member 5.6, for example a metal cap, is fixed. 7 is a chain and is attached to the conductive member 5. Therefore, since the conductive member 5 holds the fourth electrode, it becomes the t-pole of the living body 1i411, and the conductive member 6 becomes the discharge side electrode that discharges the electrostatic difference from the living body.

電撃の発生は皆無となる。In the present invention, a resistor 1 having a non-linear voltage t* property is used. This way)
Since the resistor 1 was used, the band #L1 released from the living body
Most of the energy is converted into thermal energy by the resistor 1, and the rest is released from the discharge side electrode 6 to the ground line. Therefore, the fIIE charge due to °C1 static electricity is resistor 1t"
The n1 discharge 111, which generates heat and consumes °C, is reliably discharged from the pole 6, and there is no electric shock caused by changes in the discharge gap as in the conventional example.

ー量を小さくすることができる。The resistance value of the resistor is within the range of 10 to 10Ω. This resistance value range was selected on the basis that the time constant of discharge can be increased, and the current due to discharge can be reduced and the amount of energy consumed within a unit time can be reduced.

It exhibits a high resistance of 1,000 MΩ, but when the voltage increases to several KV, the resistance value decreases to, for example, several tens of Ω. For this reason, for example, when discharging the charged charge of KV, the resistance becomes low.
It will be released as a small amount of energy to the 1-su.
