Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an antistatic device for static electricity.

[0002]

[Prior art]

 At low temperatures, human body or other objects are liable to generate static electricity due to friction. Such static electricity not only gives a shock to the human body, but especially in the clean room of the electronics industry, low voltage driven electronic parts etc. It is very important to prevent the static electricity from being charged, since it may be destroyed.

Therefore, conventionally, in a clean room, as shown in FIG. 3, an operator wears a dust-free garment 31 or the like in which conductive fibers are woven in order to prevent electrostatic charge, and the dust-free garment 31 is placed on top of A ground wire 33 is connected to the wrist band 32 attached to the arm portion, and the other end connection portion 34 of the ground wire 33 is connected to the ground 35 to discharge static electricity to the ground.

In such an antistatic device for static electricity, not only is the ground wire 33 restricted in the range of action of the worker, but the ground wire 33 must be removed when the worker leaves the work area. It took time and effort. In addition, the ground wire 35 is often installed together with a very small outlet 36 in the illustrated example, and if the ground wire connecting portion 34 comes into contact with the receptacle 36, there is a risk of electric shock and danger.

[0005]

[Problems to be solved by the device]

 In view of the above-mentioned problems of the prior art, the present invention aims to provide a static electricity protection device that is safe, easy to wear, and does not limit the range of motion of the wearer. .

[0006]

[Means for Solving the Problems]

 A needle-shaped electrode was fixedly supported on a conductive base member having a locking member formed in part so that the tip of the needle-shaped electrode was located in the air close to the base member. Further, a protective cover may be provided on the substrate so as to cover the needle electrode.

[0007]

[Action]

 At low temperature, the static electricity generated in the body due to friction is guided from the substrate to the needle-shaped electrode, and the needle-shaped electrode discharges a non-polar corona into the air.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1 and 2 show an embodiment in which the antistatic device 1 of the present invention is attached to a band 3 of a timepiece 2 to be worn on a human body.

The antistatic tool 1 has a needle-shaped electrode 5 at one end of a flat plate-shaped base body 4 made of a conductive material, and a support member 6 from one end of the base body 4 to the other end thereof, and The needle electrode 5 is supported so that it is positioned in the air close to the surface.

A semi-cylindrical protective cover 10 is provided on the surface of the substrate 4 so as to cover the needle-shaped electrodes 5 to prevent the needle-shaped electrodes 5 from being damaged and ensure the safety of the wearer. Both ends of the protective cover are opened to ensure ventilation of the needle electrode 5.

A locking member 7 having an L-shaped tip is formed at both ends of the base body 4 toward the lower side of the base body 4, and the antistatic tool 1 is appropriately attached to the member by a locking member 7. There is. In the illustrated example, the L-shaped bent portion of the locking member 7 is locked to the watch band 3, and when the watch 2 is worn on the arm 9 from above the clothes 8, the base 4 and the needle-shaped electrode 5 are Since the continuous locking member 7 is pressed against the garment 8, the surface of the garment 8 and the needle electrode 5 are brought into conduction.

In the above-described embodiment, the case where the antistatic device 1 of the present invention is locked to the watch band 3 is shown, but it is of course possible to use a separate wrist band (not shown). Also, by appropriately changing the shape of the locking member 7, it is possible to wear it with accessories such as a belt, a tie pin, a necklace, and a ring, or to wear it by directly locking it to clothes, and to attach a ground wire or the like. Since it is not necessary, it can be used in any environment, and it is effective not only for use in clean rooms in electronic industries but also for passengers in passenger aircraft where static electricity is likely to occur.

Next, the operation will be described based on the example of the above embodiment.

The static electricity generated by friction at low temperatures reaches several thousands to tens of thousands of volts. On the other hand, since a non-polar corona discharge into the air by the needle electrode is generated from about 2000V, when the antistatic device 1 of the present invention is attached, the static electricity generated in the body is generated by the conductive locking member 7 and When the needle-shaped electrode 5 is guided to the needle-shaped electrode 5 through the substrate 4 and the electric potential at the needle-shaped electrode 5 becomes 2000 V or more, corona discharge occurs in the air and the body is prevented from being charged.

When the potential of the discharge of static electricity generated in the body is 2000 V or less, non-polar corona discharge from the antistatic device 1 does not occur, but at a residual potential of about 2000 V, a shock to the human body and destruction of electronic parts are caused. Therefore, it can be said that the antistatic effect of the antistatic device 1 of the present invention is sufficient for use.

[0016]

[Effect of device]

 As described above, the antistatic device of the present invention has a needle-shaped electrode on a conductive base member having a locking member formed on a part thereof, so that the tip of the needle-shaped electrode is located in the air close to the base member. Since it is fixedly supported, static electricity on the human body can be prevented, it is safe and easy to wear, and the wearer can move freely while wearing it. Further, since the protective cover is provided on the base body so as to cover the needle-shaped electrode, damage to the needle-shaped electrode can be prevented and the wearer is also safe.
