Description

  The present invention relates to a static eliminator and a static eliminator method.

  In daily life, for example, when a person walks, static electricity is generated due to friction with clothes. Also, carpets are often laid in the hallways and lobby of buildings, and static electricity is generated in the body by walking on the carpets. These static electricity are accumulated as charges on the human body and clothes without being naturally discharged. As a result, if you touch the entrance of the room, door, door handle, elevator control panel, vehicle door handle, metal furniture, etc., the charge (static electricity) charged on the human body and / or clothes will drastically decrease. It is discharged and gives a strong impact to the human body.

  In addition, many integrated circuits and electronic components are used in electronic devices such as personal computers and mobile phones. When a charged person approaches or touches an electronic device, the electric charge is often electrostatically induced in the electronic device. If the electric charge accumulated in the electronic device is discharged at once, exceeding the withstand voltage of the electronic components that make up the electronic device, the discharge voltage may exceed several kilovolts. Cause failure.

  In general, as a method for mitigating the impact generated by the human body during the discharge of electric charges (static electricity), generally, grounding (earthing) is performed via a high resistance circuit (more specifically, a so-called surge absorbing circuit including a resistor). An example is a method in which a charge (static electricity) is caused to flow to the ground when a person touches the static eliminator and a person touches the static eliminator.

  Regarding electronic devices, in order to suppress the generation of high discharge voltage, mention is made of a method of incorporating a static elimination circuit that combines a coil or resistor that suppresses discharge current, a capacitor that absorbs electrostatic pulses, a Zener diode, etc. into the electronic device. be able to. Also, for example, an AC voltage that generates an ion gas group to ionize the atmosphere in the vicinity of the charged object by corona discharge to remove static electricity from a charged object (for example, a charged film or electronic component) charged by friction during transportation. A method using an application type static eliminator is known.

  Japanese Laid-Open Patent Publication No. 10-316321 (see, for example, page 3, FIG. 1 and FIG. 2) discloses a configuration in which an electrostatic absorption plate is grounded via a very high-resistance resistor with respect to an elevator hall operation panel. Has been. According to the technique disclosed in this patent publication, since the electrostatic voltage is applied to the resistor over a long period of time, not instantaneously, compared to the case without the resistor, the impact on the human body can be reduced. Has been.

  Japanese Patent Application Laid-Open No. 2001-35684 (for example, see page 2) discloses a method of grounding a metal part of a structure, a car door, or the like via a contact member. A so-called surge absorbing circuit including a resistor is incorporated in a circuit that discharges static electricity to mitigate rapid discharge.

  Japanese Patent Laid-Open No. 01-251598 (see, for example, page 2) discloses a technique for removing static electricity without attaching a conductive material to a conductive fiber and grounding it.

  Japanese Patent Application Laid-Open No. 05-174376 (see, for example, pages 2 and 4 and FIG. 1) uses an ion generator that ionizes air by applying a high voltage from a high voltage power source to an ion generating electrode. Thus, a method for neutralizing the charge charged on the polyethylene terephthalate film (PET film) is disclosed.

  Japanese Unexamined Patent Publication No. 2000-262303 (for example, page 1) discloses a product called a wrist trap as one of countermeasures against static electricity in a factory.

Japanese Patent Laid-Open No. 10-316321 (Page 3, FIGS. 1 and 2) JP 2001-35684 A (2nd page) JP-A-01-251598 (page 2) JP 05-174376 (2nd page and 4th page, FIG. 1) JP 2000-262303 A (first page)

  However, in the static elimination method using the conventional static eliminator that mitigates rapid discharge by interposing a high resistor or conductive material in the path for discharging the charge (static electricity) charged on the clothes, Since a discharge circuit is formed on the premise of grounding, and the human body becomes a part of the components of the discharge circuit, there is a considerable impact depending on the person during discharge. In addition, this conventional method has the inconvenience that a person must always come in contact with a static eliminator that is grounded. Moreover, the charged state of people varies widely, and some people are charged only slightly, while others are charged in large quantities. A person who is charged in a large amount may not be able to avoid an impact by a static elimination method (grounding method) using a conventional static elimination device.

  In addition, the method of incorporating the static eliminator circuit into an electronic device also has a problem that the static eliminator circuit must always be grounded. Furthermore, in the case of an electronic device, there is a case where noise from the ground is picked up by grounding, which hinders the operation of the electronic device. In particular, the spread of mobile phones in recent years is remarkable, but due to the nature of mobile phones, it is difficult to ground, and failures that are thought to be caused by static electricity charged on the human body have occurred. The AC voltage application type static eliminator used in the method of removing the static electricity of the charged object by ionizing the atmosphere in the vicinity of the charged object by corona discharge is expensive, and it is necessary to supply power for generating the ion gas group And

  In the technique disclosed in Japanese Patent Application Laid-Open No. 10-316321, it is difficult to determine whether or not the neutralization has been performed reliably because there is no problem such as a danger in the event of a leakage or the neutralization state is not notified. There's a problem.

  In the technique disclosed in Japanese Patent Application Laid-Open No. 2001-35684, there is a case where a person may receive an impact, and inconvenience that a metal part of a structure to be contacted with a contact member or a car door must be searched. There is.

  In the technique disclosed in Japanese Patent Application Laid-Open No. 01-251598, static electricity is removed by air discharge. Therefore, if there is flammable gas or organic solvent in the vicinity of the place where static electricity is removed, explosion or ignition will occur. There is danger. Therefore, there is a limit to the place of use.

  In the technique disclosed in Japanese Patent Application Laid-Open No. 05-174376, an expensive ion generator is required, and electric power for generating ions is required.

  In the technique disclosed in Japanese Patent Laid-Open No. 2000-262303, it is necessary to ground the wrist trap, and a wiring (cord) for grounding is attached, which is inconvenient in work.

  Accordingly, an object of the present invention is to provide a static eliminator having a simple structure that can be used in a wide range of fields and ranges, improving the drawbacks of the prior art, and a static eliminator using the static eliminator. Is to provide.

  In the present invention, the electrostatically induced charge is discharged by the discharge means (or second discharge means described later). The concept of “discharge” includes the energy based on the charge as the discharge means (or , A concept of being converted into heat by a second discharge unit (to be described later), and a concept of being converted to light by a discharge unit (or a second discharge unit to be described later). Here, the potential difference at both ends of the discharge means (or second discharge means described later) due to the electric charge stored between the first conductor piece and the second conductor piece due to dielectric polarization is a discharge. When the discharge start voltage of the means (or second discharge means described later) is exceeded, the electric charge is discharged by the discharge means (or second discharge means). Electrostatic induction is a phenomenon in which when an object that is not charged is placed near an electrostatic charged body such as a charged human body or object, the material constituting the object is polarized and the object is also charged with electricity.

Specifically, in order to light the discharge tube reliably, the value obtained by adding the discharge start voltage of the second varistor to the discharge start voltage of the discharge tube is lower than the value of the discharge start voltage of the first varistor. Thus, it is preferable to select the first varistor, the second varistor, and the discharge tube. In addition, by setting it as such a structure, the voltage which remains in the static eliminating device after discharge can be made still lower than in the 1st form of this invention. Moreover, a discharge state can be confirmed by providing a discharge tube.

  Here, the varistor is a two-terminal element whose resistance value decreases nonlinearly as the applied voltage increases. In other words, the varistor is a two-terminal element that has a high resistance almost equal to that of an insulator up to the discharge start voltage, but the resistance value decreases abruptly when the applied voltage exceeds the discharge start voltage and becomes almost conductive. is there. The charges electrostatically induced in the first conductor piece and the second conductor piece and stored (accumulated) by the dielectric polarization are consumed as heat by the internal resistance of the varistor. That is, the static electricity is very high in voltage but has a very small current value, so that it is sufficiently consumed by the internal resistance of the varistor. Specifically, varistors can be classified into diode varistors (cuprous oxide varistors, selenium varistors, silicon varistors, silicon Zener diodes) and ceramic varistors (zinc oxide varistors, barium titanate varistors, silicon carbide varistors). it can. In the present invention, although not limited, it is preferable to use a ceramic varistor as a varistor from the viewpoint of miniaturization of the static eliminator. In the present invention, when the static eliminator is portable, a chip varistor is mainly used. When the static eliminator is a mounting type (fixed type), it is desirable to use a varistor as large as possible. .

  A discharge tube is an electric characteristic that accompanies impact ionization between electrons emitted from the cathode and the enclosed gas or vapor by enclosing a gas in a container evacuated to a low pressure and applying a voltage between the electrodes.

The charges electrostatically induced in the first conductor piece and the second conductor piece and stored (accumulated) by dielectric polarization are consumed as light during discharge in the discharge tube. By observing the light emission in the discharge tube, the start, continuation, and completion of the discharge can be confirmed.

  Furthermore, the air gap is an air discharge gap separated by two electrodes. The charges electrostatically induced in the first conductor piece and the second conductor piece and stored (accumulated) by the dielectric polarization are consumed as heat by the discharge in the air gap.

In the present invention, it is preferable to use a material having an electric resistance value of 10 ⁷ Ω / cm or more as a material constituting the insulating layer or a flat plate material constituting the insulating layer.

Examples thereof include representative metals and alloys; conductive rubbers; conductive fibers; and cured conductive pastes. As a method for forming the penetrating portion in the insulating layer, an appropriate method may be adopted depending on the material constituting the insulating layer.

  Although the first conductor piece and / or the second conductor piece is arranged on the insulating layer depending on the material constituting the insulating layer, the first conductor piece and / or the second conductor piece is arranged.

  When an electrostatically charged body, which is a charged person, object, or article, is brought into contact with the first conductor piece, charge is electrostatically induced in the first conductor piece and the second conductor piece. The electrostatically induced charge is stored between the first conductor piece and the second conductor piece by dielectric polarization, and then the first conductor piece and the second conductor piece are grounded. In a state where the discharge is not performed, the discharge is performed by the discharge unit (or the discharge unit and / or the second discharge unit). After that, for example, even if a person touches another metal member (for example, a room entrance, a gate, a door handle, an elevator operation panel, a vehicle door handle, a metal furniture), the human body will not suffer severe pain. . Alternatively, no discharge occurs between the object or article and another metal member. For example, when the second conductor piece is grounded, even if the static eliminator is disposed so as to face each other through the insulating layer, the first conductor piece and the second conductor piece, and As a result of the electric current flowing to the ground instantly, even if the discharge means has one end electrically connected to the first conductor piece and the other end electrically connected to the second conductor piece.

In the present invention, the first conductor piece and the second conductor piece are not grounded, and the electric charge is consumed as heat or light in the discharge means or the second discharge means, and the human body Does not become a part of the components of the discharge circuit, so there is no severe pain in the human body.

  In addition, when the static eliminator of the present invention is incorporated in a key for opening and closing a vehicle or a door, a person simply touches the first conductor piece of the static eliminator of the present invention incorporated in the key. As a result, it is possible to remove the charge without touching anywhere, so that even if the vehicle or the door is touched thereafter, the person is not shocked.

  Further, in the static eliminator of the present invention, the discharge of the charge is processed inside the discharge means or the second discharge means, so that it is not affected by the external atmosphere. Furthermore, in processes such as film transport and small electronic component manufacturing, it is difficult to remove the charges charged on the film and electronic components during movement because it is difficult to ground the moving film and electronic components. It is extremely difficult to use an ion generator or a spray for removing static electricity. In the present invention, since grounding is not required, electric charges charged on the film and the electronic component during movement can be easily removed.

  As described above, the static eliminator of the present invention can be a portable type or an attachment type (fixed type) depending on the intended use, and either type can sufficiently exhibit the effect. In addition, there is no inconvenience such as having to search for a metal part of a structure to be brought into contact with the contact member, a door of a car, or the like, and inconvenience such as complicated work by wiring (cord) for grounding.

(4) Unlike the conventional static electricity removing apparatus using ions, no expensive ion generator or power for generating ions is required.
(5) By mounting the static eliminator of the present invention on a portable electronic device, not only does the portable electronic device fail due to static electricity but also the person carrying the portable electronic device is portable. By making contact with the first conductor piece of the static eliminator in the electronic device, it is possible to always remove static electricity from the human body.
(6) The removal of static electricity is a phenomenon inside the discharge means or the second discharge means, and the charge is safely discharged by the discharge means or the second discharge means without being affected by the external atmosphere. Therefore, there are no restrictions on the place of use.
(7) Static electricity can be easily removed from a moving object or article without grounding even during the movement of an easily charged object or article in various processes.

  Hereinafter, the present invention will be described based on an embodiment with reference to the drawings, but before that, based on (A), (B), (C) and (D) of FIG. An outline of the static electricity removal method will be described.

  Specific conceptual diagrams and equivalent circuit diagrams of the static eliminator and static eliminator of the present invention are shown in FIGS. 1A and 1B and FIGS. 1C and 1D. Here, the specific conceptual diagram shown in FIG. 1A and the equivalent circuit diagram shown in FIG. 1B relate to the first embodiment of the present invention, and the specific concept shown in FIG. The equivalent circuit diagram shown in FIG. 1 and FIG. 1D relates to the second embodiment of the present invention. In FIGS. 1B and 1D, reference numeral 21 indicates the specific resistance value of the conductor piece, and reference numeral 22 indicates the distributed capacitance of the insulating layer 11.

  In the first embodiment of the present invention, as shown in FIGS. 1A and 1B, the static eliminator is a first conductor piece arranged to face through the insulating layer 11. 12 and the second conductor piece 13, and discharge means having one end electrically connected to the first conductor piece 12 and the other end electrically connected to the second conductor piece 13. ing. Here, in the example shown in the first embodiment of the present invention, the discharge means is composed of a varistor 14. Then, the electrostatic charge induced in the first conductor piece 12 and the second conductor piece 13 by bringing the electrostatic charging body 20 (for example, a human finger) into contact with the first conductor piece 12, After electricity is stored between the first conductor piece 12 and the second conductor piece 13 by dielectric polarization, the first conductor piece 12 and the second conductor piece 13 are not grounded. Discharged by the discharging means. That is, when the electrostatic charging body 20 comes into contact with the first conductor piece 12, the second conductor piece 13 positioned with the insulating layer 11 in between is opposite to the case where the first conductor piece 12 is charged. The charge of the pole is electrostatically induced and charged, and the charge (static electricity) is stored (accumulated) between the first conductor piece 12 and the second conductor piece 13 by dielectric polarization. When the potential difference between the first conductor piece 12 and the second conductor piece 13 due to the electric charge becomes equal to or higher than the discharge start voltage of the varistor 14, the electric charge is discharged by the varistor 14 serving as a discharging means. start. Specifically, the electric charge is consumed as heat by the internal resistance of the varistor 14. The discharge start voltage of the varistor in the various examples relating to the first aspect of the present invention is not limited, but is 280 volts, for example.

  On the other hand, in the second embodiment of the present invention, as shown in FIGS. 1C and 1D, the static eliminator is electrically connected at one end to the first conductor piece 12, Second discharge means is further provided with the other end electrically connected to the second conductor piece 13. Here, in the illustrated example in the second mode of the present invention, the discharge means is composed of the first varistor 114, and the second discharge means is the second varistor 115 and the discharge tube connected in series. (More specifically, a neon tube) 116. Then, the electrostatic charge induced in the first conductor piece 12 and the second conductor piece 13 by bringing the electrostatic charging body 20 (for example, a human finger) into contact with the first conductor piece 12, After electricity is stored between the first conductor piece 12 and the second conductor piece 13 by dielectric polarization, the first conductor piece 12 and the second conductor piece 13 are not grounded. Discharge is performed by the first varistor 114 serving as the discharge means, and the second varistor 115 and the discharge tube 116 serving as the second discharge means. Note that the discharge start voltage of the second discharge means is lower than the discharge start voltage of the discharge means. Specifically, when the electrostatic charging body 20 comes into contact with the first conductor piece 12, the first conductor piece 12 is charged to the second conductor piece 13 positioned with the insulating layer 11 interposed therebetween. The opposite pole charges are electrostatically induced and charged, and charges (static electricity) are stored (accumulated) between the first conductor piece 12 and the second conductor piece 13 by dielectric polarization. When the potential difference between the first conductor piece 12 and the second conductor piece 13 due to the charge becomes equal to or higher than the discharge start voltage of the second discharge means, the charge is transferred by the second discharge means. A discharge is started by the second varistor 115 and the discharge tube 116. Specifically, the electric charge is consumed as heat by the internal resistance of the second varistor 115, is consumed as light by the discharge tube 116, and is consumed as heat by the internal resistance of the first varistor 114. Incidentally, the discharge start voltages of the first varistor, the second varistor, and the discharge tube in various examples relating to the second aspect of the present invention are not limited to, for example, 280 volts, 24 volts, 80 volts. That is, the discharge start voltage of the discharge means is 280 volts, and the discharge start voltage of the second discharge means is 104 volts (= 24 volts + 80 volts).
