JP 2000-340393 A

  In the conventional static eliminator, the voltage supply wire is connected to the discharge electrode using a coupling member such as a connector. However, since this type of static eliminator uses a coupling member such as a connector, the price of the static eliminator has to be high.

  An object of the present invention is to provide a static eliminator capable of reducing the price as compared with the prior art.

  The static eliminator of the present invention includes a discharge electrode, a case in which the discharge electrode is accommodated, and a voltage supply wire that supplies a voltage to the discharge electrode. In the present invention, the core wire of the voltage supply wire is directly attached to the conductive attachment member to which the discharge electrode is fixed. In this case, it is not necessary to use a coupling member such as a connector, so that the price of the static eliminator can be significantly reduced as compared with the conventional case. The structure of the discharge electrode is arbitrary.

  A more specific configuration of the static eliminator to which the present invention is applied is as follows. That is, a more specific static eliminator includes an insulating case having an ion emission opening, a discharge electrode disposed inside the insulating case, and a conductive attachment in which the discharge electrode is fixed and fixed to the insulating case. A member and an insulating coated electric wire electrically connected to the conductive attachment member. In the insulating case, a discharge electrode is disposed on the side of the ion emission opening, and a conductive attachment member is disposed on the side opposite to the ion emission opening. The insulating case is formed with an introduction port for introducing an insulating coated electric wire therein. Furthermore, the core wire end portion of the insulation-coated electric wire located in the insulating case is connected to the conductive mounting member using solder or a conductive adhesive. And the to-be-stored part of the insulation coating electric wire accommodated in the insulation case is deform | transformed so that a bending part may be formed in the middle. In this way, if a bent part is formed in the middle of the covered part of the insulated sheathed wire, when a pulling force or a pressing force is applied to the insulated sheathed electric wire, the force is applied to the end of the core wire of the insulated sheathed cable due to the deformation of the bent portion. Direct transmission to the connecting portion between the portion and the conductive attachment member can be prevented. Therefore, even when the end portion of the core wire is directly attached to the conductive connection member, it is possible to effectively prevent the occurrence of connection failure.

  It is preferable to fit a cylindrical bush made of rubber or insulating resin that can be deformed so as to be in close contact with the inner surface of the inlet and the outer surface of the covering portion of the insulated wire in the inlet provided in the insulating case. When such a cylindrical bush is fitted into the introduction port, the movement of the insulation-coated electric wire can be restricted.

  When a plurality of static eliminators are connected in series, the insulating case of the static eliminator is electrically connected to a conductive connection member to supply a high voltage to another static eliminator electrically connected in series. It is necessary to form another introduction port for introducing another insulation-coated electric wire. And the end part of the core wire of another insulation-coated electric wire located in the insulating case is also connected to the conductive mounting member using solder or a conductive adhesive. Further, the portion to be accommodated of the other insulated wire stored in the insulating case is also deformed so that a bent portion is formed in the middle. In this way, even when a plurality of static eliminators are sequentially connected in series using a plurality of insulation-coated wires, the insulation-coated wires and the conductive connection members can be easily connected, and each insulation-coated wire It is possible to prevent connection failure between the core wire end and the conductive attachment member.

  In the case where an inlet and another inlet are formed in the insulating case, the two inlets are preferably formed in the insulating case so as to face each other. In this case, it is preferable that the portion to be accommodated of the insulated coated electric wire and the portion to be accommodated of the other insulated coated electric wire are deformed so that the distance between each other is minimized near the conductive connecting member. With this configuration, when a pressing force is applied to the two insulated wires, the bent portions abut against each other to prevent further deformation, and the bent portions function as a stopper. Strength against pressure can be increased. In addition, if it does in this way, the bending part of the to-be-accepted part of an insulation coating electric wire will be bent so that the angle between the two covered electric wire parts of the both sides of this bending part may be 90 degree | times. Also, in this case, the insulating case has an ion emission opening at one end and the first storage area on the side opposite to the ion storage opening and the first storage area in which the conductive connection member is stored. And a second storage area communicating with the inside. The introduction port and another introduction port are provided at a position communicating with the second storage area.

  The insulating case is a combination of a pair of insulating case halves configured to have mating surfaces at positions where the inlet, another inlet, and the ion emission opening are divided into two parts. It is preferred to use what is constructed. When using such a pair of insulating case halves, when connecting the core wires of the two insulated wires to one conductive connecting member, one side of the conductive connecting member is entirely exposed, Connection work can be done easily. In addition, after the connection work is finished, in the state where the cylindrical bush fitted to the insulation-covered electric wire is inserted into the half-split inlet and the other inlet formed in one half of the insulating case and temporarily fixed, Assembly can be performed by fitting the insulating case to one insulating case. Therefore, even if the bent portion is formed in the insulated wire, there is an advantage that the insulated wire is not easily detached during the assembly of the insulated case.

  According to the static eliminator of the present invention, since it is not necessary to use a coupling member such as a connector, there is an advantage that the price of the static eliminator can be significantly reduced as compared with the conventional case.

  Hereinafter, an embodiment of the static eliminator of the present invention will be described with reference to the drawings. 1A and 1B are a front view and a bottom view of the static eliminator of the present embodiment. FIG. 2 is a cross-sectional view showing the internal structure of the static eliminator of FIG. FIG. 3 is an enlarged view of the discharge electrode used in the static eliminator of the present embodiment fixed to the conductive attachment member. In these figures, what is indicated by reference numeral 1 is the static eliminator of the present embodiment.

  The static eliminator 1 includes an insulation case 3, a discharge electrode 5, a conductive attachment member 7, and an insulation-coated electric wire 13. As will be described in detail later, the insulating case 3 has a hollow structure formed by combining two insulating case halves 3a and 3b made of insulating resin. An ion emission opening 4 is provided at one end of the insulating case 3. A saddle 2 used when installing the static eliminator 1 in various devices is provided at the end of the insulating case 3 opposite to the ion emission opening 4. In addition, a pair of inlets 17 and 19 are formed in the pair of side walls of the insulating case 3 in order to introduce insulating coated wires 13 and 15 to be described later. Inside the insulating case 3, a discharge electrode 5 is disposed on the side of the ion emission opening 4, and a conductive attachment member 7 is disposed on the side opposite to the ion emission opening 4.

  In the present embodiment, the discharge electrode 5 is composed of a bundle 6 of a plurality of conductive fibers. The conductive fiber to be used is a stainless fiber having a fiber radius of 0.2 to 0.4 mm. In this embodiment, 40 to 100 conductive fibers are bundled in a flat brush shape. It was. The discharge electrode 5 is fixed to the conductive attachment member 7. The conductive attachment member 7 is a conductive member for fixing the discharge electrode 5 to the insulating case 3, and is composed of a conductive metal plate in this example. A through hole 7 a for screwing is provided in a substantially central portion of the conductive attachment member 7. As shown in FIG. 2, the conductive mounting member 7 is attached to the insulating case 3 by passing the screw 8 through the through hole 7a of the conductive mounting member 7 and screwing it to the inner wall portion of the insulating case half 3a. Is fixed.

  As shown in FIG. 2, the end portions of the core wires 14 and 16 located in the insulating case 3 are connected to the conductive attachment member 7 by soldering. In addition, as a method for connecting the ends of the core wires 14 and 16 of the insulation-coated wires 13 and 15 to the conductive attachment member 7, a connection method using a conductive adhesive can be employed instead of soldering. In the present embodiment, the core wires 14 and 16 of the insulation-coated wires 13 and 15 (voltage supply wires) are directly attached to the conductive attachment member 7 to which the discharge electrode 5 is fixed. By adopting such a configuration, it is not necessary to use a coupling member such as a connector, and therefore the price of the static eliminator can be significantly reduced as compared with the conventional case.

  In the present embodiment, the accommodated portions 13a and 15a of the insulation-coated wires 13 and 15 accommodated in the insulation case 3 are deformed so as to form the bent portions 13b and 15b in the middle. If bent portions 13b and 15b are formed in the middle of the accommodated portions 13a and 15a of the insulated sheathed wires 13 and 15, even when a pulling force or pressing force is applied to the insulated sheathed wires 13 and 15 from the outside of the insulating case 3. By deforming the bent portions 13b and 15b, it is possible to prevent those forces from being directly transmitted to the connection portion between the end portions of the core wires 14 and 16 of the insulation-coated wires 13 and 15 and the conductive attachment member 7. Therefore, even when the end portions of the core wires 14 and 16 are directly attached to the conductive connection member 7, it is possible to effectively prevent the occurrence of connection failure.

  As shown in FIG. 2, the introduction ports 17 and 19 provided in the insulating case 3 are in close contact with the inner surfaces 17 a of the introduction ports 17 and 19 and the outer surfaces 13 c and 15 c of the covering portions of the insulation-coated wires 13 and 15. Deformable rubber bushed cylindrical bushes 21 and 23 are fitted. When the tubular bushes 21 and 23 with hooks are fitted into the introduction ports 17 and 19, not only the tubular bushes 21 and 23 are not removed due to the presence of the hooks, but also the insulated coated wires 13 that penetrate the tubular bushes 21 and 23. , 15 can be restricted. The cylindrical bushes 21 and 23 may be made of rubber as long as they can be deformed so as to be in close contact with the inner surfaces 17a of the introduction ports 17 and 19 and the outer surfaces 13c and 15c of the covering portions of the insulating coated wires 13 and 15. Of course, it is not limited to the cylindrical bush, and a cylindrical bush made of insulating resin may be used.

  Next, an example of a coupling structure of the discharge electrode 5 and the conductive attachment member 7 used in the static eliminator of the present embodiment will be described with reference to FIGS. FIG. 4 is a process diagram in which the process of fixing the discharge electrode 5 to the conductive attachment member 7 is viewed from the lateral direction. FIG. 5 is a diagram illustrating the process of fixing the discharge electrode 5 to the conductive attachment member 7. FIG. 6 is a view seen from the back surface of the member 7. First, as shown in FIGS. 4A and 5A, a plurality of conductive fiber bundles 6 and conductive attachment members 7 are prepared. The conductive attachment member 7 has a plate shape having a front surface 7a and a back surface 7b opposed to each other in the thickness direction.

  As shown in FIG. 4 (B) and FIG. 5 (B), a conductive adhesive tape 8 is previously attached to one end 6 of the bundle 6 of the plurality of conductive fibers. It is pasted. In this example, the bundle 6 of a plurality of conductive fibers is bundled in a flat brush shape. When such an adhesive tape 8 is used, it is possible to prevent the bundle of conductive fibers 6 from falling apart when performing a caulking operation using a caulking metal fitting 9 to be described later, which facilitates the caulking operation. In this example, the plurality of conductive fiber bundles 6 are bundled in a flat brush shape, but may be bundled in a round brush shape, and the method of bundling is arbitrary. In addition, as in this example, when a plurality of conductive fiber bundles 6 are bundled in a flat brush shape, a later-described caulking metal fitting 9 at one end 6a of the plurality of conductive fiber bundles 6 is used. The adhesive tape 8 may also be applied to the surface 6d facing the surface. In the present embodiment, since the adhesive tape 8 is only attached to one surface, even if the adhesive tape 8 has an insulating property, the other surface of the bundle 6 of conductive fibers is conductive. Therefore, it is possible to ensure contact with the conductive mounting member 7 or the caulking metal fitting 9 described later, and electrical continuity can be ensured.

  In the present embodiment, a double-sided adhesive tape is used as the adhesive tape 8. Therefore, as shown in FIGS. 4C and 5C, one surface 6c of one end 6a of the bundle 6 of conductive fibers is made conductive through this double-sided adhesive tape (adhesive tape 8). It joins to the surface 7a of the attachment member 7. In this manner, the caulking operation with the caulking metal fitting 9 is performed in a state in which one end portion 6a of the bundle 6 of the conductive fibers is temporarily fixed to the conductive mounting member 7 using the double-sided adhesive tape (adhesive tape 8). Therefore, workability can be greatly improved. In this example, a thermosetting conductive adhesive tape is used as the double-sided adhesive tape (adhesive tape 8). Therefore, even after caulking with a caulking metal fitting 9 to be described later, the presence of the adhesive tape is an obstacle to the electrical connection between the conductive mounting portion 7 and the caulking metal fitting 9 and the bundle 6 of conductive fibers. Absent.

  Next, in the process of FIG. 4D and FIG. 5D, the caulking metal fitting 9 is attached so that one end portion 6 a of the bundle 6 of the plurality of conductive fibers is sandwiched between the conductive attachment member 7. It is caulked against the conductive mounting member 7. The caulking metal fitting 9 is a metal fitting for restraining one end 6a of the bundle 6 of the plurality of conductive fibers by caulking and fixing the bundle 6 of the conductive fibers to the conductive mounting member 7, The shape, material, etc. can be arbitrarily determined. In this example, the caulking metal fitting 9 is formed of a material (aluminum) that can be easily deformed. The caulking metal fitting 9 may be formed integrally with the conductive attachment member 7. In this example, since the caulking metal fitting 9 and the conductive attachment member 7 are formed separately, the conductive attachment member 7 is formed of a conductive material that is difficult to deform, and the caulking metal fitting 9 is made of aluminum or the like used in this example. Thus, it can be formed of a material that can be easily deformed. If it does in this way, it will become possible to perform attachment of conductive attachment member 7 in the reliable and stable state.

  As shown in FIG. 5C, the caulking metal fitting 9 includes a contact portion 9a that comes into contact with the other surface 6d of one end portion 6a of the bundle 6 of conductive fibers, and both ends 9a 'and 9a of the contact portion 9a. 'And a pair of caulking portions 9b and 9c that are integrally provided to ′ and caulked so as to come into contact with the back surface 7b of the conductive attachment member 7. Such a caulking metal fitting 9 is easy to manufacture and obtain, and can be easily caulked, which contributes to reducing the manufacturing cost of the discharge electrode.

  In the present embodiment, as shown in FIG. 5C, the tip surface 7c ′ of the end portion 7c of the conductive attachment member 7 to which one end portion 6a of the bundle 6 of conductive fibers is fixed, The caulking metal fitting 9 is connected to the distal end surface 7c of the conductive mounting member 7 so as to protrude from the contact portion 9a of the caulking metal fitting 9 and the pair of caulking portions 9b, 9c (so as to protrude leftward when viewed in the drawing). It is caulked to the conductive mounting member 7 at a position descending from 'to the through hole 7d side. 4 (E) and 5 (E), the adhesive (the bundle 6 of conductive fibers) spreads over the contact portion 9a of the caulking metal fitting 9 and the bundle 6 of conductive fibers. And a pair of caulking portions, and an end portion 7c of the conductive mounting member 7 protruding from the pair of caulking portions 9b and 9c. 9b, 9c and the bundle 6 of conductive fibers are coated with an adhesive 11 (a spread preventing means for preventing the bundle 6 of conductive fibers from spreading) to form the back side covering portion 10b. ing. By forming such front and back side covering portions 10a and 10b, the electrical connection between the conductive fiber bundle 6 and the conductive attachment member 7 can be strengthened. Further, the conductive fiber can be prevented from being broken by rubbing against the edge portion of the tip end surface 7c ′ of the conductive attachment member 7. In this example, the adhesive 11 (spreading prevention means) is applied to a portion 6b of the bundle 6 of conductive fibers adjacent to one end 6a of the bundle 6 of conductive fibers and not restrained by the caulking fitting. The fiber 6 is impregnated so as to prevent the part 6b of the bundle 6 from spreading. As the adhesive 11, a silicone adhesive having fluidity is used. The adhesive 11 (spreading prevention means) is not limited to such a synthetic resin-based adhesive, and various adhesives (glue etc.) such as starch-based and cellulose-based adhesives are used as spread prevention means. Can do. When the adhesive 11 is impregnated in the portion 6b of the bundle 6 of conductive fibers, the spread of the conductive fibers can be prevented with a simple structure. Note that the application range of the adhesive 11 may be determined in any way as long as a plurality of discharge portions composed of the end portions of the respective conductive fibers remain at the front end 6a of the conductive fibers. For example, the adhesive can be applied to the vicinity of the tip of the bundle 6 of conductive fibers. When a silicone-based adhesive is applied as in the present embodiment, specifically, as shown in FIGS. 3B and 3C, the base (part 6b) of the bundle 6 of conductive fibers is Covering portions 10a and 10b having a certain thickness are formed. The covering portions 10a and 10b serve to prevent the discharge electrodes from being entangled or caught with other discharge electrodes when the discharge electrodes are mass-produced and when the discharge electrodes are automatically fed by the automatic parts feeder.

  Further, the adhesive 11 not only restrains the conductive fibers located on the surface portion of the bundle 6 of the plurality of conductive fibers, but also penetrates into the inside of the bundle. You can combine them. Therefore, even when used for a long period of time, the portion solidified by the adhesive 11 does not spread, and the spreading of the conductive fibers can be effectively prevented. In addition, although the spread of the fiber occurs in the portion not impregnated with the adhesive 11, it is possible to effectively prevent the conductive fiber from spreading more than necessary by appropriately determining the region impregnated with the adhesive 11. it can. As a result, the discharge from each tip 6a of the plurality of conductive fibers can be maintained for a long time.

  Further, since the adhesive 11 is applied across the portion 6b of the bundle 6 of conductive fibers and the caulking metal fitting 9, the gap between the caulking metal fitting 9 and the conductive fiber bundle 6 is formed in the gap. Dust can be prevented from entering. Further, even if the caulking state by the caulking metal fitting 9 varies, there is an advantage that the electrical and mechanical coupling between the conductive fiber bundle 6 and the caulking metal fitting 9 can be assisted by the adhesive. As mentioned above, although the manufacturing process of the discharge electrode 5 used with the static eliminator 1 of this Embodiment was described, the manufacturing method of the discharge electrode used with the static eliminator of this invention is not limited to said manufacturing process. Of course, any manufacturing method can be used.

  Returning to FIG. 1, in the static eliminator of the present embodiment, a guard member 12 is provided in the ion emission opening 4 of the insulating case 3. The guard member 12 does not inhibit the discharge of ions and prevents the intruding material from entering the discharge electrode 5 as much as possible by preventing the intruding material from entering through the ion emission opening 4. effective. Therefore, when such a guard member 12 is provided, the safety of the static eliminator can be improved. In this example, the guard member 12 is provided, but providing the guard member 12 is optional.

  In the present embodiment, the inlet 17 and the other inlet 19 in the insulating case 3 are formed in the insulating case 3 so as to face each other. The accommodated portion 13a of the insulated wire 13 and the accommodated portion 15a of the other insulated wire 15 are respectively deformed so that the distance between them is minimized near the conductive connecting member 7. Yes. With such a configuration, even when a pressing force is applied to the two insulated wires 13 and 15, the bent portions 13 b and 15 b hit each other to prevent further deformation, and the bent portions 13 b and 15 b Therefore, the proof stress against the pressing force to the insulation coated wires 13 and 15 can be increased.

  In this example, the bent portions 13b and 15b of the receiving portions of the insulated wires 13 and 15 are bent so that the angle between the two covered wire portions on both sides of the bent portions 13b and 15b is 90 degrees. ing. The insulating case 3 has an ion emission opening 4 at one end and a first storage area 25 in which the conductive connection member 7 is stored and a first storage on the opposite side of the ion emission opening 4. A second storage area 27 communicating with the area 25 is included inside. The introduction port 17 and another introduction port 19 are provided at a position communicating with the second storage region 27.

  The insulating case 3 includes a pair of insulating case halves configured to have mating surfaces at positions where the introduction port 17, another introduction port 19, and the ion emission opening 4 are divided into two parts ( One insulating case half 3a shown in FIGS. 1 and 2 and the other insulating case half 3b) shown in FIG. 1 are combined. When such a pair of insulating case halves are used, when connecting the core wires 14 and 16 of the two insulated wires 13 and 15 to one conductive connecting member 7, one side of the conductive connecting member 7 is entirely disposed. Connection can be easily performed. Further, as shown in FIG. 2, after the connection work was completed, the insulation-covered electric wires 13 and 15 were fitted into the half-split introduction port 17 and another introduction port 19 formed in one half of the insulating case 3 a. Assembly can be performed by fitting the other insulating case 3b into one insulating case 3a in a state where the cylindrical bushes 21 and 23 are inserted and temporarily fixed. Therefore, even if the bent portions 13b and 15b are formed on the insulating coated wires 13 and 15, there is an advantage that the insulating coated wires 13 and 15 are not easily detached during the assembly of the insulating case 3.

  Note that the static eliminator shown in FIGS. 1 and 2 is a type of static eliminator connected in series. When only one static eliminator is used alone, only one insulation-coated electric wire in the above embodiment is used. For example, when the insulated wire 13 is used, a cap made of an insulating rubber material is fitted into the introduction port 19.

  FIG. 6 is a perspective view when a plurality of static eliminators of the present embodiment are connected in series. Using this figure, a plurality of static eliminators (static eliminators 1A, 1B, 1C) are sequentially connected in series using insulated coated electric wires 13A, 15A, 13B, 15B, 13C, 15C). Even if a plurality of static eliminators are connected in series as described above, if the static eliminator of the present embodiment is used, the insulation-coated electric wire and the conductive connection member can be connected, and each insulation-coated electric wire It is possible to prevent the connection portion connection failure between the core wire end portion and the conductive attachment member.

  FIG. 7 is a diagram illustrating a positional relationship between each static eliminator and a static elimination object when the plural static eliminators of FIG. 6 are used. In FIG. 7, a voltage of 9000 volts and 10 mA is supplied to each discharge electrode. From the static eliminator group (1A, 1B, 1C) in FIG. (+) Corona discharge is generated, and from the neutralizer group (1D, 1E, 1F) of FIG. Different voltages are applied from the power supply. The static elimination object 31 is formed on the paper surface of FIG. 7 with respect to the positive (+) static eliminator group (1A, 1B, 1C) and the negative (−) static eliminator group (1D, 1E, 1F). Move in the orthogonal direction. (1A, 1B, 1C) and the static eliminator group (1D, 1E, 1F) are arranged 300 to 500 mm apart in a direction orthogonal to the paper surface. The distance d1 from the lower ends 1A ′, 1B ′, 1C ′ of the plus (+) static eliminator groups 1A, 1B, 1C to the static elimination object 31 is 300 to 500 mm. Further, the distance d2 from the lower ends 1D ', 1E', 1F 'of the negative (-) static eliminator groups 1D, 1E, 1F to the static elimination object 31 is also 300 to 500 mm. In the present embodiment, by performing the plus (+) ion discharge and the minus (−) ion discharge at the same time, the charge removal target 31 is discharged while maintaining the ion balance.
