[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-63396 Summary of the Invention [Problem to be solved by the invention]

[0008] When moving the current sensor, the gripping casing is gripped with a gripping tool such as insulated pliers, but it can be difficult to adjust the gripping method of the gripping tool to suit the work environment.

[0009] Furthermore, such problems can occur with electrical devices other than current sensors, such as CT receivers, which are attached to overhead lines and used in general.

[0010] In view of the above circumstances, an object of the present invention is to provide an electrical device for overhead lines that allows the gripping method of the gripping tool to be easily adapted to a gripping method suited to the work. [Means for solving the problem]

[0011] The electrical equipment for overhead lines of the present invention comprises: a device body that is attached to the overhead line; a gripping attachment part attached to the device body, the gripping attachment portion has a pair of gripping walls that extend outward from the device body and can be gripped by a gripping tool; The pair of gripping walls are arranged opposite to each other with a gap therebetween that allows the gripping tool to be inserted and removed.

[0012] According to the electrical equipment for overhead lines having the above-described configuration, a pair of gripping wall portions facing each other with a gap between them are attached to the main body of the equipment, so that one of the gripping wall portions can be gripped with a gripping tool, or the other gripping wall portion can be gripped with a gripping tool.

[0013] Furthermore, since the pair of gripping wall portions are opposed to each other, it is possible to grip the pair of gripping wall portions together with a gripping tool.

[0014] Therefore, the electrical equipment for overhead lines can easily adapt the gripping method of the gripping tool to a gripping method suitable for the work.

[0015] In the electrical equipment for overhead lines of the present invention, The gripping attachment portion may have an abutment wall portion that is arranged between the pair of gripping wall portions and configured to abut against each of the pair of gripping wall portions, and that is arranged opposite the device main body with a gap between it and the device main body that allows the gripping tool to be inserted and removed.

[0016] In this way, the gripping tool inserted at the removable interval is surrounded by the device body and the pair of gripping walls and abutment wall, making it difficult for the overhead line electrical device to fall off the gripping tool.

[0017] In the electrical equipment for overhead lines of the present invention, The pair of gripping wall portions have opposing surfaces facing each other, The gripping mounting portion has an inner reinforcing portion that is disposed between the pair of gripping wall portions and is configured to abut against the opposing surfaces of the pair of gripping wall portions in a first direction in which the pair of gripping wall portions are aligned. This may be done.

[0018] In this way, when a pair of gripping wall portions are gripped together, the pair of gripping wall portions are supported from the inside by the inner reinforcement portion, thereby preventing the gripping wall portions from being damaged. [Effects of the Invention]

[0019] As described above, the electrical equipment for overhead lines of the present invention can achieve the excellent effect of making it easy to adapt the gripping method of the gripping tool to a gripping method suitable for the work. [Brief explanation of the drawings]

[0023] The device body 2 of this embodiment is a current detector that detects the flow of current through an electric wire.

[0024] As shown in FIG. 2, the device main body 2 has a box-shaped housing 20 and a mounting portion 21 that is provided on the housing 20 and that is attached to the overhead wire.

[0025] The housing 20 is box-shaped and includes a front surface 200, a rear surface 201, a pair of side surfaces 202 and 203, a top surface 204, and a bottom surface 205.

[0026] In the following description, the direction in which the pair of side surfaces 202, 203 are aligned will be referred to as the first direction, the direction in which the front surface 200 and the back surface 201 are aligned will be referred to as the second direction, and the direction in which the top surface 204 and the bottom surface 205 are aligned will be referred to as the third direction. In addition, in the third direction, the direction from the top surface 204 side toward the bottom surface 205 side will be referred to as the downward direction, and the direction from the bottom surface 205 side toward the top surface 204 side will be referred to as the upward direction.

[0027] The mounting portion 21 has a pair of mounting arms 210 that are arc-shaped and have one end in the circumferential direction (hereinafter referred to as the base end) rotatably mounted to the housing 20 .

[0028] The pair of mounting arms 210 are configured to extend upward from the top surface 204 of the housing 20. Furthermore, the inner circumferential surfaces of the pair of mounting arms 210 face each other in the first direction.

[0029] The pair of mounting arms 210 are configured so that, by rotating with respect to the housing 20, the other end portions (hereinafter referred to as tip portions) of the mounting arms 210 in the circumferential direction can be moved toward and away from each other.

[0030] In the following description, a state in which the tip ends of the pair of mounting arms 210 are abutted against each other will be referred to as a closed state, and a state in which the tip ends are spaced apart will be referred to as an open state.

[0031] In the mounting portion 21, when the pair of mounting arms 210 are in the open state, an electric wire can be placed between the respective tips of the pair of mounting arms 210 and between the inner surface of one mounting arm 210 and the inner surface of the other mounting arm 210.

[0032] Furthermore, the pair of mounting arms 210 are configured so that when they are in a closed state with the electric wires disposed between their respective inner circumferential surfaces, they can surround the electric wires.

[0033] The gripping attachment part 3 comprises a pair of gripping walls 30 arranged on the housing 20 so as to face different side surfaces 202, 203 of the housing 20, a stop wall part 31 arranged between the pair of gripping walls 30 and configured to abut against each of the pair of gripping walls 30, the stop wall part 31 being arranged opposite the device main body 2 with a gap between it and the device main body 2 (specifically, between it and the front surface 200 of the housing 20) that allows the gripping tool to be inserted and removed, a covering wall part 32 arranged between the pair of gripping walls 30 and configured to abut against each of the pair of gripping walls 30, the covering wall part 32 being arranged overlapping the outer surface of the device main body 2 (specifically, the back surface 201 of the housing 20), a holding structure 33 that holds the pair of gripping wall portions 30, the abutting wall portion 31, and the covering wall portion 32 in an assembled state with the device main body 2 disposed between the pair of gripping wall portions 30; It has.

[0034] In the gripping attachment part 3 of this embodiment, the pair of gripping walls 30, the abutting wall 31, the covering wall 32, and the holding structure 33 are all configured as separate bodies.

[0035] The grip wall portion 30 is plate-shaped. The grip wall portion 30 of this embodiment has an overlapping portion 300 arranged to overlap the side surfaces 202 and 203 of the housing 20, a front-side extending portion 301 extending outward from the overlapping portion 300 beyond the front surface 200 of the housing 20 in the second direction, and a back-side extending portion 302 extending outward from the overlapping portion 300 beyond the back surface 201 of the housing 20 in the second direction.

[0036] The overlapping portion 300 has a screw hole 3000 formed therein, which penetrates in the first direction, at a position where the overlapping portion 300 overlaps with the housing 20 in the first direction.

[0037] The screw hole 3000 is used to prevent displacement of the housing 20 disposed between the pair of gripping wall portions 30. More specifically, a male screw member can be screwed into the screw hole 3000 from the outer side in the first direction, and by abutting the tip of the male screw member against the housing 20, movement of the housing 20 relative to the pair of gripping wall portions 30 can be restricted.

[0038] The front extension portion 301 has an opposing surface 3010 that is arranged facing the front extension portion 301 of the adjacent grip wall portion 30, and an outward surface 3011 that is arranged facing the opposite side to the opposing surface 3010.

[0039] The distance between the front extension 301 of one grip wall 30 and the front extension 301 of the other grip wall 30 in the first direction is set to a distance wide enough to allow the gripping tool to be inserted and removed.

[0040] The gripping tool T is an instrument (e.g., insulated pliers) having a pair of gripping opening / closing parts T1 that can be opened and closed, as shown in Figures 5(a) and 5(b), and that has a pair of gripping opening / closing parts T1 that grip the object to be gripped.

[0041] The distance between the front extension portion 301 of one grip wall portion 30 and the front extension portion 301 of the other grip wall portion 30 in the first direction is set to a width that allows one of the pair of grip opening / closing portions T1 to be inserted and removed.

[0042] An anti-slip portion 34 is attached to the outward surface 3011 of the grip wall portion 30 to prevent the grip opening / closing portion T1 from slipping relative to the grip wall portion 30. The anti-slip portion 34 in this embodiment is made of rubber.

[0043] 4, the front extending portion 301 extends outward in the second direction from the overlapping portion 300 when viewed from the outward surface 3011. Furthermore, the front extending portion 301 is disposed at a position shifted outward in the third direction from the housing 20, and is configured not to overlap with the housing 20 in the third direction.

[0044] Furthermore, the front extension portion 301 is formed so that one end in the first direction is positioned at a position shifted outward from one end of the overlapping portion 300 (a position shifted outward in the first direction), and the other end in the first direction is positioned at a position shifted outward from the other end of the overlapping portion 300 (a position shifted outward in the first direction).

[0045] That is, both ends of the front extending portion 301 in the first direction protrude outward beyond the overlapping portion 300 in the first direction.

[0046] As shown in Figure 2, the back extension portion 302 has an opposing surface 3020 that is arranged toward the back extension portion 302 of the adjacent gripping wall portion 30, and an outward surface 3021 that is arranged toward the opposite side from the opposing surface 3020.

[0047] The abutment wall portion 31 has an abutment wall main body 310 that abuts against each opposing surface 3010 of the pair of gripping wall portions 30 in the first direction, and a pair of abutment stop protrusions 311 that each protrude outward in the first direction from separate end faces of the abutment wall main body 310 in the first direction.

[0048] As described above, the abutment wall portions 31 are disposed opposite the device main body 2 (front surface 200 of housing 20) with a gap therebetween that allows the grip opening / closing portion of the gripping tool to be inserted and removed. Therefore, in the electric device 1 of this embodiment, when the grip opening / closing portion is inserted between the pair of gripping walls 30, the device main body 2, the pair of gripping walls 30, and the abutment wall portions 31 surround the periphery of the grip opening / closing portion.

[0049] Therefore, the gripping opening / closing portion inserted into the enclosed area surrounded by the front surface 200 of the housing 20, the opposing surfaces 3010 of the front extension portions 301 of each of the pair of gripping wall portions 30, and one surface of the abutment wall portion 31 arranged toward the housing 20 side is prevented from escaping from the enclosed area.

[0050] The abutment stop wall portion 31 is preferably disposed closer to one side or the other side in the third direction. In this embodiment, the abutment stop wall portion 31 is disposed closer to one side (upper side) in the third direction of the gripping wall portion 30. Therefore, the other side (lower side) in the third direction of the space between the pair of gripping wall portions 30 is open in the third direction and the second direction (see FIG. 1).

[0051] One of the pair of abutment stop protrusions 311 is inserted into a through hole 3012 formed in the front extension portion 301 of one of the gripping wall portions 30, and the other of the pair of abutment stop protrusions 311 is inserted into a through hole 3012 formed in the front extension portion 301 of the other gripping wall portion 30.

[0052] As a result, the abutment wall portion 31 is positioned relative to the pair of gripping wall portions 30 .

[0053] The covering wall portion 32 has a covering wall main body 320 that abuts against each of the pair of gripping wall portions 30 in the first direction, and a pair of covering wall protrusions 321 that each protrude outward in the first direction from separate end faces of the covering wall main body 320 in the first direction.

[0054] One of the pair of covering wall protrusions 321 is inserted into a through hole 3022 formed in the back extension portion 302 of one of the gripping wall portions 30, and the other of the pair of covering wall protrusions 321 is inserted into a through hole 3022 formed in the back extension portion 302 of the other gripping wall portion 30.

[0055] As a result, the covering wall portion 32 is positioned relative to the pair of gripping wall portions 30 .

[0056] As described above, in the gripping attachment part 3 of this embodiment, the abutting wall part 31 and the covering wall part 32 are disposed between the pair of gripping walls 30 and abut against each of the pair of gripping walls 30. Therefore, in the gripping attachment part 3, the abutting wall part 31 and the covering wall part 32 constitute an inner reinforcing part that is disposed between the pair of gripping walls 30 and abuts against each of the opposing surfaces 3010 of the pair of gripping walls 30 in the first direction.

[0057] The holding structure 33 has a fixing shaft portion 330 that is columnar and has threaded holes formed on both ends in the axial direction, a first male threaded portion 331 that is inserted from the outward surface 3011 side into a through hole 3013 that is formed in the front extension portion 301 of one of the pair of gripping wall portions 30 and screws into one of the threaded holes of the fixing shaft portion 330, and a second male threaded portion 332 that is inserted from the outward surface 3011 side into a through hole 3013 that is formed in the front extension portion 301 of the other of the pair of gripping wall portions 30 and screws into one of the threaded holes of the fixing shaft portion 330.

[0058] The pair of gripping wall portions 30 receive a force from the holding structure 33 that moves them toward each other, so that the housing 20 is sandwiched in the first direction by the overlapping portions 300 of the pair of gripping wall portions 30, the abutment wall portion 31 is sandwiched in the first direction by the front extension portions 301 of the pair of gripping wall portions 30, and the covering wall portion 32 is sandwiched in the first direction by the back extension portions 302 of the pair of gripping wall portions 30.

[0059] The space between the pair of gripping walls 30 includes a storage area for storing the housing 20 and an enclosed area for inserting and removing the gripping tool (specifically, the gripping opening / closing part), with the enclosed area formed on one side in the second direction and the storage area formed on the other side in the second direction. The fixing shaft 330 forms the boundary between the storage area and the enclosed area.

[0060] The containing area and the enclosing area are open both upward and downward (i.e., open to both sides in the third direction). As for the enclosing area, as described above, the lower side is also open in the second direction.

[0061] As shown in FIG. 3, the mounting portion cover 4 has a pair of cover portions 40 each attached to a separate mounting arm portion 210 .

[0062] The tip side 400 of the inward surface of the cover portion 40 is formed so as to move outward in the first direction as it approaches the tip, and the base side 401 of the inward surface of the cover portion 40 is formed so as to move outward in the first direction as it approaches the base end.

[0063] Further, a tip end side 400 of the inward surface of the cover portion 40 has a curved shape, and a base end side 401 of the inward surface of the cover portion 40 is formed in a straight line.

[0064] The configuration of the electric device 1 according to this embodiment is as described above. Next, a method of using the electric device 1 will be described.

[0065] First, the gripping wall portion 30 is gripped with a gripping tool T such as insulating pliers. At this time, only one of the pair of gripping wall portions 30 may be gripped with the gripping tool T (see FIG. 5(a)), or only the other of the pair of gripping wall portions 30 may be gripped with the gripping tool T (see FIG. 5(b)).

[0066] In this case, one of the pair of gripping opening / closing parts T1 is inserted into the enclosed area, preventing the electrical device 1 from falling off from the gripping tool T. Furthermore, the lower side of the enclosed area is open in the third direction and the second direction, so the gripping opening / closing part T1 can be inserted straight into the enclosed area along the third direction, or the gripping opening / closing part T1 can be inserted obliquely into the enclosed area.

[0067] When a pair of gripping wall portions 30 are gripped together by a gripping tool T, the pair of gripping wall portions 30 may be gripped from below (see Figure 6(a)), or the pair of gripping wall portions 30 may be gripped from the side (see Figure 6(b)).

[0068] The worker selects how to grip the electric device 1 with the gripping tool T, taking into consideration the situation of the work site, such as the arrangement of obstacles around the installation site.

[0069] Then, while maintaining the gripping wall portion 30 gripped by the gripping tool T, the electrical device 1 is moved to the installation location (see Figure 7(a)), the mounting portion 21 is attached to the electric wire C (see Figure 7(b)), and the gripping wall portion 30 is released (see Figure 7(c)).

[0070] When attaching the mounting portion 21 to the electric wire C, the tip side 400 of the inward surface of each cover portion 40 is abutted against the electric wire C, and the electrical device 1 is pressed toward the electric wire C, causing the electric wire C to open each cover portion 40 and the mounting arm portion 210, and when the tip side 400 of the inward surface of each cover portion 40 passes over the electric wire C, the open cover portions 40 and the mounting arm portion 210 close, thereby surrounding the electric wire C with the pair of mounting arms 210.

[0071] When removing the electrical device 1 from the electric wire C, the gripping wall portion 30 of the electrical device 1 installed on the electric wire C is grasped with the gripping tool T, and the base end side 401 of the inward surface of each cover portion 40 is abutted against the electric wire C, and the electrical device 1 is pulled in a direction away from the electric wire C.

[0072] In this way, the cover parts 40 and the mounting arms 210 are opened again by the electric wire C, and when the tip side 400 of the inward surface of each cover part 40 passes over the electric wire C, the open cover parts 40 and the mounting arms 210 are closed, thereby detaching the electric device 1 from the electric wire C.

[0073] The electric device 1 of this embodiment is attached to and detached from the electric wire C in this manner.

[0074] As described above, according to the electrical device 1 of this embodiment, a pair of gripping wall portions 30 facing each other with a gap between them are attached to the device main body 2, so that one gripping wall portion 30 can be gripped by the gripping wall portion 30, or the other gripping wall portion 30 can be gripped by the gripping wall portion 30.

[0075] In addition, since the pair of gripping wall portions 30 face each other, it is possible to grip the pair of gripping wall portions 30 together with the gripping tool T.

[0076] In this way, the electrical equipment 1 for overhead lines can be held in different ways using the gripping device T, making it easier to move the electrical equipment 1 for overhead lines regardless of the installation location, which has the excellent effect of making it easier to install on the overhead lines.

[0077] Furthermore, in the electrical equipment 1, the gripping attachment portion 3 is connected to each of the pair of gripping wall portions 30 and has abutment stop wall portions 31 that are arranged opposite the equipment main body 2 with a gap between them that allows the gripping tool T to be inserted and removed.As a result, the gripping tool T inserted into the insertion and removal area is surrounded by the equipment main body 2, the pair of gripping wall portions 30, and the abutment stop wall portions 31, making it difficult for the electrical equipment 1 for overhead lines to fall off the gripping tool T.

[0078] Furthermore, since the abutment stop wall portion 31 is disposed closer to one side (upper side) in the third direction, the lower side of the enclosed area is widely open, making it easier to insert the gripping tool T into the enclosed area.

[0079] Furthermore, in the electrical device 1 of this embodiment, the abutment wall portion 31 and the covering wall portion 32 arranged between the pair of gripping wall portions 30 are formed to extend straight in the first direction and constitute inner reinforcement portions that abut against the respective opposing surfaces 3010 of the pair of gripping wall portions 30, making them less likely to be damaged when the pair of gripping wall portions 30 are gripped together.

[0080] Furthermore, the abutment wall portion 31 and the covering wall portion 32 are configured as separate bodies from the pair of gripping wall portions 30, making them less susceptible to damage.

[0081] The electrical equipment for overhead lines according to the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0082] In the description of the electric device 1 of the above embodiment, the device body 2 is a current detector as an example, but is not limited to this configuration. For example, the device body 2 may be an electric device 1 other than a current detector.

[0083] In the above embodiment, the gripping wall portion 30 has the anti-slip portion 34 attached to the outward surface 3011, but is not limited to this configuration. For example, the gripping wall portion 30 may have the anti-slip portion 34 attached to both the outward surface 3011 and the opposing surface 3010.

[0084] In the above embodiment, the abutment stop wall portion 31 is disposed closer to one side (upper side) in the third direction of the gripping wall portion 30, but is not limited to this configuration. For example, the abutment stop wall portion 31 may be disposed closer to the other side (lower side) in the third direction of the gripping wall portion 30. In this case, one side (upper side) in the third direction of the space between the pair of gripping wall portions 30 is open in the third direction and the second direction.

[0085] In the above embodiment, the pair of gripping wall portions 30 are configured to extend forward from the device main body 2, and this extending portion (in the above embodiment, the front extending portion 301) is configured to be grippable by the gripping tool T, but this configuration is not limited to this.

[0086] For example, the pair of gripping wall portions 30 may be configured to extend rearward from the device body 2 so that this extending portion can be gripped by the gripping tool T, or may be configured to extend downward from the device body 2 so that this extending portion can be gripped by the gripping tool T. In the electric device 1 of the above embodiment, when the portion of the pair of gripping wall portions 30 to be gripped by the gripping tool T is made to extend rearward, the portion to be gripped by the gripping tool T may be made to extend rearward from the back-side extending portion 302.
