Description

Technical Field

[0001] The present disclosure relates to a sheet fixture used when fixing an insulating sheet to an object to be fixed.

Background Art

[0002] Conventionally, for example, in low-voltage electrical work such as cubicles, since the inside of the cubicle is made of a metal frame or door, it is necessary to insulate with an insulating sheet or the like to prevent ground faults and short circuits, and a sheet having electrical insulation properties (that is, an insulating sheet) or the like has been used.

[0003] When using this insulating sheet, as shown in FIG. 10, the insulating sheet (P1) is arranged to cover electrical equipment (P2), a door (P3), etc. inside the cubicle, and the insulating sheet is fixed by sandwiching the electrical equipment, the door, etc. from above the insulating sheet with a clip whose tip side opens and closes (that is, a sheet clip: P4). Note that various structures of clips can be used (see, for example, Patent Document 1).

[0004] Also, when the insulating sheet cannot be fixed with a clip, a vinyl tape (P5) was used to attach the insulating sheet to the door of the cubicle or the like.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the conventional technology, since the insulating sheet is fixed to the door of the cubicle or the like using a clip or a vinyl tape, there are the following problems. When fixing the insulating sheet using a clip, there was a limitation on the fixing location.

[0007] For example, clips can be used when the edge of a door or the object is small. When the electrical equipment is large or the door is large, the clip cannot reach the position where the insulating sheet needs to be fixed. As a result, the insulating sheet cannot be fixed with the clip at the position where it is desired to be fixed.

[0008] Also, when the insulating sheet could not be fixed with the clip, the insulating sheet was fixed to the cubicle door or the like using vinyl tape. However, when there was a lot of moisture, the insulating sheet might peel off.

[0009] Furthermore, when the clip pinched the electric wire or the electrical equipment, there were cases where the screw at the connection point between the electric wire and the equipment became loose or came off, or the operation handle of the switch was accidentally moved. One aspect of the present disclosure aims to provide a sheet fixture that can improve the workability when fixing an insulating sheet to a fixing object and can also improve the safety of the work.

Means for Solving the Problems

[0010] (1) One aspect of the present disclosure relates to a sheet fixture used when fixing an insulating sheet having electrical insulation to a fixing object. The sheet fixture includes a resin structure made of a resin having electrical insulation. The resin structure has a long plate-shaped fixing portion having a contact surface in contact with the insulating sheet, and a handle portion provided on the side opposite to the contact surface of the fixing portion and extending so as to connect both end portions in the longitudinal direction of the fixing portion. The fixing portion and the handle portion are configured in an annular shape. Further, a magnet is provided inside the fixing portion.

[0011] In the present disclosure, when the fixing object can be adsorbed by the magnetic force of the magnet, by using the sheet fixture, the workability when fixing the insulating sheet to the fixing object can be improved, and the safety of work such as electrical work can also be improved.

[0012] Specifically, when an object to be fixed such as an electrical device or a door around it is covered with an insulating sheet, by bringing the contact surface of the sheet fixture into contact with the insulating sheet from above, the magnetic force (and thus the adsorption force) of the magnet within the fixing portion can adsorb the sheet fixture to the object to be fixed with the insulating sheet sandwiched therebetween. In this way, the insulating sheet can be easily fixed to the object to be fixed by the sheet fixture, improving workability.

[0013] Also, when using a clip, there are many restrictions such as the clip not reaching during fixing, but in the case of the present disclosure, such restrictions are few. That is, if the sheet fixture can be adsorbed to the object to be fixed by the magnetic force of the magnet, the insulating sheet can be fixed at almost any position, improving workability.

[0014] Also, since vinyl tape does not adhere to wet locations, even in a humid environment, the insulating sheet can be more reliably fixed compared to vinyl tape, effectively suppressing electrical accidents such as electric shock, ground fault, and short circuit.

[0015] Furthermore, since the resin structure of the sheet fixture uses an electrical insulating material, it is also possible to effectively suppress electrical accidents such as electric shock, ground fault, and short circuit when performing various inspections such as low-voltage electrical work.

[0016] (2) In another aspect of the present disclosure, the contact surface of the fixing portion may be a flat surface. In the case of such a configuration, when the surface of the object to be fixed is flat, the contact surface of the fixing portion and the object to be fixed face each other over a large area via the insulating sheet. Therefore, the sheet fixture and the object to be fixed are strongly adsorbed by the magnetic force of the magnet in the fixing portion, having the advantage that the insulating sheet is difficult to peel off.

[0017] (3) In another aspect of the present disclosure, the interior of the fixing portion has a housing hole for housing the magnet, the housing hole extends in the longitudinal direction of the fixing portion, and one or both ends in the longitudinal direction are open at the opening, and a closing member may be attached to cover the opening.

[0018] In the case of such a configuration, a magnet can be accommodated in the accommodation hole of the fixing portion with respect to the formed resin structure. Further, by closing the opening portion with a closing member after the accommodation, it is possible to suppress the dropping of the magnet. That is, with the configuration of the present disclosure, it is possible to easily manufacture the sheet fixture.

[0019] (4) In another aspect of the present disclosure, the object to be fixed is capable of being adsorbed by a magnet, and is disposed on an insulating sheet covering the object to be fixed, and is used to fix the insulating sheet to the object to be fixed by the magnet.

[0020] Thus, in the present disclosure, the insulating sheet can be easily fixed to the object to be fixed by the adsorption force of the magnet of the sheet fixture.

Mode for Carrying Out the Invention

[0022] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. First Embodiment] The sheet fixture of the first embodiment is a tool for fixing an insulating sheet having electrical insulation to an object to be fixed.

[0023] [1-1. Configuration] As shown in FIGS. 1 and 2, the sheet fixture 1 of the first embodiment is an annular sheet fixture having a through hole (manual hole) 3 in the central portion.

[0024] Hereinafter, the description will be made using XYZ coordinates, which are three-dimensional orthogonal coordinates. The Z-axis direction is the vertical direction (height direction), the Y-axis direction is the front-rear direction (longitudinal direction), and the X-axis direction is the left-right direction (lateral direction). The upper side in FIG. 2(B) is the upper side in the Z-axis direction, and the lower side in FIG. 2(B) is the lower side in the Z-axis direction. The right side in FIG. 2(B) is the right side in the X-axis direction, and the left side in FIG. 2(B) is the left side in the X-axis direction. The left side in FIG. 2(D) is the front side in the Y-axis direction, and the right side in FIG. 2(D) is the rear side in the Y-axis direction.

[0025] The sheet fixture 1 is point-symmetrical about the Z-axis (when passing through the center of gravity) in a plan view seen from the Z-axis direction. That is, it has the same shape when rotated 180° with the Z-axis as the center of rotation. Further, the sheet fixture 1 is line-symmetrical about the Z-axis when viewed from the front side, the rear side, the right side, and the left side.

[0026] Hereinafter, a specific description will be given. <Sheet Fixture> As shown in FIGS. 1 and 2, the sheet fixture 1 is mainly composed of a resin structure 5 made of a resin having electrical insulation properties, and a magnet member 7 (see FIG. 5C) is disposed inside thereof. As will be described later, the resin structure 5 is composed of a main body portion 9 and a pair of caps 11.

[0027] As the resin having electrical insulation properties, for example, polyethylene, polypropylene, polycarbonate, etc. can be adopted. The sheet fixture 1 (and thus the resin structure 5) has a fixing portion 13 and a gripping portion 15, and is formed in a ring shape by the fixing portion 13 and the gripping portion 15. That is, a handling hole 3 is formed surrounded by the fixing portion 13 and the gripping portion 15.

[0028] The fixing portion 13 is a long plate-like member, and has a contact surface 17 in contact with an insulating sheet S (see FIG. 7) described later on its lower surface. The contact surface 17 is a substantially rectangular flat plane.

[0029] The gripping portion 15 has a substantially U-shaped shape (see FIG. 2B) when viewed from the Z-axis direction, and is provided on the side opposite to the contact surface 17 of the fixing portion 13. The gripping portion 15 extends so as to connect both end portions 13a and 13b in the longitudinal direction (X-axis direction) of the fixing portion 13.

[0030] Specifically, the gripping portion 15 is composed of a plate-like gripping part 19 extending in parallel with the fixing portion 13, and a pair of left and right legs 21 extending along the Z-axis direction from both ends in the longitudinal direction of the gripping part 19 toward the fixing portion 13 side. Note that the gripping part 19 is a part where an operator places a finger (i.e., a part to be grasped by hand), as will be described later.

[0031] As shown in FIG. 2(B), both legs 21 are orthogonal to the fixing portion 13 and the gripping portion 19, but the outer and inner sides (the side of the handling hole 3) of the connection portion between both legs 21 and the gripping portion 19 are smoothly curved. Also, the inner side (the side of the handling hole 3) of the connection portion between both legs 21 and the fixing portion 13 is smoothly curved. Thereby, the inner peripheral surface of the handling hole 3 is substantially rectangular when viewed from the Y-axis direction, and the four corners are smoothly curved.

[0032] On the other hand, the outside of the connection portion between the both leg portions 21 and the fixing portion 13 is not smoothly curved, and from both end portions 13a and 13b of the fixing portion 13 (and thus the contact surface 17) in the X-axis direction, the outside of the both leg portions 21 has a shape that stands vertically.

[0033] Note that, from both end portions 13a and 13b of the fixing portion 13 (and thus the contact surface 17) in the X-axis direction, the outside of the both leg portions 21 may have a shape that stands vertically after passing through an arc so as not to damage the soft insulating sheet S.

[0034] Particularly in this first embodiment, as will be described later, a magnet member 7 (see FIG. 5C) is accommodated inside the fixing portion 13, and this magnet member 7 is arranged so as not to be exposed to the outside. Note that the dimensions of the sheet fixture 1 are, for example, 25 mm in length × 85 mm in width × 50 mm in height, and the allowable range of each dimension is, for example, ±2 mm. The dimensions of the hand hole 3 are, for example, 35 mm in height × 70 mm in width. The thickness of the gripping portion 19 in the Z-axis direction is, for example, 8 mm.

[0035] <Main body portion, cap, magnet member> As shown in FIGS. 3 and 4, the main body portion 9 is obtained by removing a pair of caps 11 from the resin structure 5, and has substantially the same shape as the sheet fixture 1.

[0036] As shown in FIGS. 4(B) and 5A, in the portion of the main body portion 9 corresponding to the fixing portion 13, an accommodation hole 23 for accommodating the magnet member 7 is provided so as to penetrate the fixing portion 13 in the longitudinal direction (X-axis direction).

[0037] The accommodation hole 23 is a substantially rectangular parallelepiped-shaped space, extends in the longitudinal direction of the fixing portion 13, and both ends in the longitudinal direction are open at the openings 25. Note that the fixing part 13 is provided with a total of four locking holes 27 for fixing the caps 11 so as to communicate with the outside in the Y-axis direction of the accommodation hole 23. Specifically, two locking holes 27 are provided on the left and right sides of the rear side wall 13c of the accommodation hole 23, and two locking holes 27 are provided on the left and right sides of the front side wall 13d of the accommodation hole 23 (see Fig. 5A).

[0038] As shown in Fig. 5B, the thickness between the lower surface 23a of the accommodation hole 23 and the contact surface 17 is, for example, 1 mm, and the allowable range is, for example, ±0.2 mm. Further, as shown in Fig. 5C, the magnet member 7 is composed of, for example, a well-known neodymium magnet 31 having a rectangular parallelepiped shape and a yoke 33 made of an iron plate or the like, which is a material with a high magnetic permeability and is arranged in a substantially U shape so as to surround the neodymium magnet 31 from three directions except for the adsorption side (the lower side in Fig. 5C). The magnet member 7 is accommodated in the accommodation hole 23 with the side where the neodymium magnet 31 is exposed being the lower side in Fig. 5B.

[0039] Also, it is desirable to use the yoke 33 because the adsorption force increases, but it is also possible to omit the yoke 33. Note that the dimensions of the magnet member 7 are, for example, 13.5 mm in length × 80 mm in width × 5 mm in height, and the adsorption force of the magnet member 7 is, for example, 330 N.

[0040] Then, the caps 11 are respectively attached so as to cover (i.e., block) the opening 25 of the accommodation hole 23. As shown in Fig. 6, the cap 11 is composed of a long plate-shaped closing part 41 having a substantially rectangular parallelepiped shape and a pair of left and right legs 43 provided on one side in the thickness direction of the closing part 41.

[0041] The pair of legs 43 extend so that the distance between them widens towards the tip, and locking protrusions 45 protruding outward are provided at each tip. Since the pair of legs 43 have elasticity, each tip can bend inward.

[0042] Here, a method of attaching the cap 11 to the opening 25 will be described. First, insert the magnet member 7 from the opening 25 into the accommodation hole 23. Next, attach each cap 11 so as to close each opening 25.

[0043] Specifically, narrow the tips of the pair of leg portions 43 of the cap 11 and insert them into the accommodation hole 23. When the locking protrusions 45 at the tips of the respective leg portions 43 inserted into the accommodation hole 23 reach the locking holes 27, the tips of the respective leg portions 43 of the cap 11 open outward in the Y-axis direction and fit into the locking holes 27 respectively. Thereby, the cap 11 closes the opening 25 and is fixed to the fixing portion 13.

[0044] [1-2. Method of Using the Sheet Fixture] <Adsorption Method> First, the case where the sheet fixture 1 is adsorbed to a fixing object K, that is, a member such as iron (iron plate, etc.) to which a magnet can be adsorbed, will be described.

[0045] As shown in FIG. 7A, an insulating sheet S having electrical insulation properties such as a low-pressure sheet is disposed on the surface of the fixing object K by the hand of an operator. As the insulating sheet S, for example, a low-pressure sheet with a thickness of 0.54 mm can be adopted.

[0046] Note that as the material of the insulating sheet S, for example, polyethylene, ethylene vinyl acetate resin, polyvinyl chloride, etc. can be adopted. Also, pass the finger of the operator through the handling hole 3 of the sheet fixture 1 to hold the sheet fixture 1 by hand. In this state, with the contact surface 17 of the sheet fixture 1 facing the surface of the insulating sheet S on the fixing object K, bring the sheet fixture 1 closer to the insulating sheet S from the vertical direction (arrow A direction) and bring the contact surface 17 into contact with the surface of the insulating sheet S.

[0047] Thereby, due to the magnetic force of the magnet member 7 of the sheet fixture 1, the sheet fixture 1 is firmly adsorbed to the fixing object K, so that the insulating sheet S between the fixing object K and the sheet fixture 1 is firmly fixed.

[0048] Incidentally, in this case, the strength (peeling strength) when peeling the sheet fixture 1 vertically from the object K to be fixed was 36 N. Also, the strength (displacement strength) when shifting the insulating sheet S was 48 N.

[0049] <Adsorption method> Next, the case of peeling the sheet fixture 1 from the object K to be fixed will be described. When peeling the sheet fixture 1 from the object K (and thus the insulating sheet S), a large force is applied when pulling the sheet fixture 1 in the direction opposite to the arrow A. Therefore, the sheet fixture 1 is peeled by rotating it.

[0050] Specifically, as shown in FIG. 7B, of the contact surface 17 of the fixing portion 13 of the sheet fixture 1, the side H extending in the longitudinal direction (the vertical direction in FIG. 7B) is used as the axis of rotation, and the sheet fixture 1 is rotated in the counterclockwise direction (arrow B direction) when viewed from above.

[0051] That is, the gripping portion 19 of the sheet fixture 1 is rotated in the direction of arrow B. As a result, the adsorption force is greatly reduced, so that the sheet fixture 1 can be easily peeled from the insulating sheet S as it is.

[0052] <Example of using the sheet fixture> Next, an actual usage example of the sheet fixture 1 will be described. Here, as shown in FIG. 8, for example, a low-voltage electrical work (for example, various electrical inspections) related to an electrical device (for example, a switch) 53 disposed in a cubicle 51 will be described as an example. Note that the iron bottom surface 57 and the door 59 of the iron frame 55 constituting the cubicle 51 are made of a material to which a magnet such as iron can be adsorbed.

[0053] First, of the surfaces of the electrical device 53 housed in the cubicle 51, the target surface is covered with a low-voltage sheet which is the insulating sheet S. Next, on the insulating sheet S, the sheet fixture 1 is disposed above the position to be fixed, and through the insulating sheet S, the sheet fixture 1 is adsorbed and fixed to the iron bottom surface 57 of the iron frame 55.

[0054] Similarly, cover the target surface of the surface of the door 59 of the cubicle 51 with the insulating sheet S. Next, place the sheet fixture 1 above the position to be fixed on the insulating sheet S, and through the insulating sheet S, adsorb and fix the sheet fixture 1 to the door 59.

[0055] In this way, by covering the surrounding members such as the electric device 53 and the surrounding door 59 with the insulating sheet S and fixing the insulating sheet S with the sheet fixture 1 coated with a resin having electrical insulation properties, it becomes possible to safely perform operations such as voltage and current inspections on the electric device 53.

[0056] [1-3. Effects] Next, the effects of the first embodiment will be described. (a) In the first embodiment, when the object K to be fixed can be adsorbed by the magnetic force of the magnet member 7, by using the sheet fixture 1, the workability when fixing the insulating sheet S to the object K can be improved, and the safety of work such as electrical work can also be improved.

[0057] Specifically, when covering the object K to be fixed such as the electric device 53 and the surrounding door 59 with the insulating sheet S, by bringing the contact surface 17 of the sheet fixture 1 into contact from above the insulating sheet S, due to the magnetic force (therefore, the adsorption force) of the magnet member 7 in the fixing portion 13, the sheet fixture 1 can be adsorbed to the object K with the insulating sheet S sandwiched therebetween. In this way, since the insulating sheet S can be easily fixed to the object K by the sheet fixture 1, the workability is improved.

[0058] In addition, since the sheet fixture 1 locks the insulating sheet S without interfering with the electric device 53, there is an advantage that it can prevent the loosening or detachment of the screws at the connection points of the electric wires and the devices, and prevent the operational error of accidentally moving the operation handle of the switchgear.

[0059] In addition, when using a clip as in the prior art, there are many limitations such as the clip not reaching when fixing, but in the case of this first embodiment, such limitations are few. That is, if the sheet fixture 1 can be adsorbed to the object to be fixed K by the magnetic force of the magnet member 7, the insulating sheet S can be fixed at almost any position, improving workability.

[0060] Also, even in a humid environment, unlike vinyl tape, the insulating sheet S can be fixed even if the surface is wet, and it is possible to effectively suppress electrical accidents such as electric shock, ground fault, and short circuit. Furthermore, since the resin structure 5 of the sheet fixture 1 is an electrical insulator (that is, the surface of the sheet fixture 1 has high electrical insulation), when performing various inspection operations such as low-voltage electrical work, electrical accidents such as electric shock, ground fault, and short circuit can be effectively suppressed. For example, it is possible to suppress short circuits and ground faults caused by metal tools during inspections, and electric shock when a person touches the charging part of the electrical equipment 53.

[0061] (b) In this first embodiment, the contact surface 17 of the fixing portion 13 is a flat surface. Therefore, when the surface of the object to be fixed K is flat, the contact surface 17 of the fixing portion 13 and the object to be fixed K face each other over a large area via the insulating sheet S. Therefore, the sheet fixture 1 and the object to be fixed K are firmly adsorbed by the magnetic force of the magnet member 7, and there is an advantage that the insulating sheet S is difficult to peel off.

[0062] (c) In this first embodiment, the magnet member 7 can be accommodated in the accommodation hole 23 of the fixing portion 13. Further, by closing the opening 25 with the cap 11 after accommodation, the dropout of the magnet member 7 can be suppressed. That is, with the configuration of this first embodiment, it is possible to easily manufacture the sheet fixture 1.

[0063] (d) In this first embodiment, the size of the sheet fixture 1 (25 mm in length × 85 mm in width × 50 mm in height) can be made smaller than that of a conventional clip (for example, 220 m in length × 115 mm in width × 25 mm in height).

[0064] (e) In this first embodiment, the weight of the sheet fixture 1 (82 g) can be reduced compared to a conventional clip (for example, 115 g). (f) In this first embodiment, since the magnet member 7 is covered with an electrically insulating resin, it has excellent electrical insulation properties.

[0065] (g) In this first embodiment, since the surface of the sheet fixture 1 is covered with an electrically insulating resin, there is an advantage that even if it is directly fixed to the surface of, for example, a painted door, the door and the like are less likely to be damaged.

[0066] (h) In this first embodiment, since a vinyl tape as in the prior art is not required, there is an advantage that no garbage is generated, it contributes to resource saving, and it is environmentally friendly. (i) In this first embodiment, since the sheet fixture 1 has a configuration in which a magnet member is incorporated, there is an advantage that the degree of freedom when fixing the insulating sheet S is high.

[0067] (j) In this first embodiment, if the sheet fixture 1 is separated from a fixing object K such as an iron door 59, it does not adsorb, but by setting the thickness of the contact surface 17 to, for example, 1 mm, sufficient adsorption force can be obtained when adsorbing.

[0068] (k) Magnets such as the neodymium magnet 31 of the magnet member 7 are easily damaged by impact or the like, but in this first embodiment, since the magnet member 7 is incorporated in the sheet fixture 1, there is an advantage that the magnet is less likely to be damaged even if there is an external impact.

[0069] [2. Second Embodiment] Since the basic configuration of the second embodiment is the same as that of the first embodiment, the differences from the first embodiment will be mainly described below. Note that the same reference numerals as those in the first embodiment indicate the same configurations, and refer to the preceding description.

[0070] Since the basic configuration of this second embodiment is the same as that of the first embodiment, the differences will be described. As shown in FIG. 9, the sheet fixture 61 of the second embodiment has a resin structure 63 having electrical insulation properties, similar to the first embodiment. Further, it has an annular configuration with a fixing portion 65 and a handle portion 67.

[0071] In particular, in the sheet fixture 61 of the second embodiment, as shown in FIG. 9B, the accommodation hole 71 for accommodating the magnet member 7 provided in the fixing portion 65 of the main body portion 69 opens only in one direction in the longitudinal direction (X-axis direction). Therefore, the cap 11 (see FIG. 9A) that closes the opening 73 of the accommodation hole 71 is also arranged only on one side. Note that the locking holes 27 for fixing the cap 11 are also only a pair of locking holes 27 corresponding to one cap 11.

[0072] The second embodiment has the same effects as the first embodiment. [3. Other Embodiments] Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above embodiments and can take various forms.

[0073] (1) For example, a magnet member may be arranged at a predetermined position (the same position as in the first embodiment) of the portion that becomes the fixing portion in the insert molding die, and a resin having electrical insulation properties (insulating resin) may be injected into the die to manufacture the sheet fixture.

[0074] In this case, except for the magnet member, the sheet fixture is entirely composed of the insulating resin. Note that since it is sufficient that at least the surface of the sheet fixture is covered with the insulating resin, the inside does not have to be the insulating resin.

[0075] As the configuration of this sheet fixture, similar to the first embodiment, a configuration having a long plate-shaped fixing portion having a contact surface in contact with the insulating sheet and a handle portion provided on the side opposite to the contact surface of the fixing portion and extending so as to connect both end portions in the longitudinal direction of the fixing portion, or a configuration formed into an annular shape by the fixing portion and the handle portion can be adopted.

[0076] (2) For example, as materials such as resins and magnets having electrical insulation properties, various well-known materials can be used. (3) The shape of the handle hole only needs to allow a person's finger to pass through and be held by hand. It is not limited to a rectangle in a front view, and various shapes can be adopted.

[0077] (4) The outer shape of the sheet fixture is not limited to a rectangle in a front view, and various shapes (for example, a shape in which the handle part is curved upward, etc.) can be adopted. (5) The sheet fixture can be used to suppress electrical accidents such as electric shock, ground fault, and short circuit during various electrical work and electrical inspections, not limited to low-voltage electrical work of AC 600V or less, such as high-voltage electrical work.

[0078] (6) The multiple functions of one component in each of the above embodiments and modification examples may be realized by multiple components, or one function of one component may be realized by multiple components. Also, multiple functions of multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Also, a part of the configuration of each of the above embodiments may be omitted. Also, at least a part of the configuration of each of the above embodiments may be added to or replaced with the configuration of other embodiments.
