Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a grounding structure for a static eliminator that enables a self-discharge type static eliminator to be grounded in a simple manner.

<Prior Art> Self-discharge type static eliminators (hereinafter abbreviated as self-discharge type static eliminators) have various structures, including a structure in which a tuft-like or sheet-like fiber electrode is held on a frame. In order to fix the fiber electrodes in such a structure, it is common practice to fix each single fiber electrode with an adhesive or an adhesive (hereinafter abbreviated as adhesive/adhesive). That is, it can be said that the fiber electrode is in an insulated state.

On the other hand, with self-discharge static eliminators, if the charged voltage of the object to be neutralized is sufficiently high (tens of thousands of volts or more), discharge will occur even when the textile electrode contributing to the discharge is insulated. For about 1,000 volts,
It is recognized that when the fiber electrode is insulated, sufficient static elimination is not performed, and that the static elimination effect is improved by grounding the fiber electrode. That is, even in the case of a self-discharge type static eliminator, it is preferably necessary to be grounded. However, in the conventional structure, the electrode fibers are insulated by adhesive or adhesive, and no effective grounding method has yet been proposed.

<Purpose of the invention> The present invention relates to the structure of a self-discharge type static eliminator that can be easily grounded even though the electrode fibers are fixed with adhesive or adhesive.

<Structure of the invention> The gist of the invention is to short-circuit the fiber electrodes together in a self-discharge type static eliminator in which a large number of fiber electrodes are fixed and covered with an insulating adhesive/adhesive. In the grounding structure of the self-discharge type static eliminator, a conductor is electrically connected to a conductor to which the static eliminator is attached, which is present on the other side of the insulating adhesive/adhesive.

Hereinafter, the content of the present invention will be explained in detail with reference to the drawings. FIG. 1 shows the structure of a conventional self-discharge type static eliminator that cannot be grounded, as a front view a and a cross-sectional view b. The fiber electrode 1 is fixed to the frame 2 with adhesive/adhesive 3 and further covered with adhesive/adhesive 4. Such a static eliminator is used by being attached to a metal frame (not shown) or the like to which it is attached using adhesive/adhesive 4. In such a structure, the frame 2 has an inverted U-shape, and a structure extending to the right of the adhesive/adhesive 4 or a plate-shaped structure similar to the frame 2 to the right of the adhesive/adhesive 4. In some cases, the electrode fibers are coated with an insulating adhesive or adhesive. In such a structure, even if the frame 2 is a conductor and the object to which it is attached with the adhesive 4 is a conductor, the fiber electrode 1 cannot be grounded.

An embodiment of the present invention will be described.

In FIG. 2, a fiber electrode 1 is fixed to a frame 2 with adhesive/adhesive 3. As shown in FIG. This structure is the same as the conventional structure, but in the present invention, there is a linear conductor 5 that short-circuits a large number of fiber electrodes 1, and a linear conductor 6 that contacts and intersects with the linear conductor 5. 2 c), a typical structure is one in which one end of the linear conductor 6 is folded back to the other side of the adhesive/adhesive 4 that fixes the fiber electrode 1 and the linear conductors 5 and 6 (Fig. 2 b). It is.

In addition to the structure described above, there is another structure in which the conductor that shorts the fiber electrodes is electrically connected to the conductor on the other side of the insulating adhesive/adhesive as shown in Figure 3a. As shown in FIG. 4, a part of the linear conductor 7 that short-circuits the fiber electrodes is folded back onto the other side of the adhesive 4, and further, as shown in FIG. The structure of the present invention can also be satisfied by a structure in which the portion is folded back to the other side of the adhesive/adhesive 4.

The fiber electrode used in the present invention is a fiber with good electrical conductivity such as stainless steel fiber or carbon fiber, and the conductor for short-circuiting or grounding it can be wire-shaped such as copper wire or aluminum wire, or it can be a strip-shaped conductor. As the material, copper foil, aluminum foil, etc. are used.

<Effects> When the self-discharge type static eliminator having the structure of the present invention is adhered or bonded to a conductor such as a metal plate with adhesive/adhesive 4, the fiber electrode 1 can be easily grounded.
It is easy to use and has great practical value as it allows the static elimination performance of the static eliminator to be improved.
