  After clamping the knob 12, as shown in FIG. 3B, the connection terminal 10 is rotated while holding the knob 12, and the connection terminal 10 is connected to the conductor as shown in FIG. 4A. Attach to 41. Specifically, the opening 11 is attached to the bolt 46.

  Here, FIG. 4B is a schematic plan view of FIG. On the conductor 41 side, the knob 12 protrudes from the one surface 10a of the connection terminal 10 in a direction substantially perpendicular to the one surface 10a. Further, the protruding member 43 protrudes in the same direction as the direction in which the knob 12 protrudes. At this time, the length that the knob 12 protrudes is longer than the length that the protruding member 43 protrudes. Thereby, a knob is clamped in the position where a clamping device does not catch on a projection member.

  On the other conductor 41 side, the bent portion 14 of the other knob 22 is plastically deformed, and the other clamping portion 23 is bent in the direction in which the current-carrying body 30 is located with the other bent portion 24 as a fold. ing. At this time, the length that the other support portion 25 protrudes is shorter than the length that the other protrusion member 53 protrudes. Further, the length that the other support portion 25 protrudes is shorter than half the width of the groove 44. As a result, another cover portion 52 is securely screwed into the screw portion 45 of the cover portion 42.

  Returning to FIG. 4A, after the opening portion 11 is attached to the bolt 46, the bolt 47 is rotated with a hexagon wrench or a flat-blade screwdriver so that the groove 47 is screwed into the screw portion 48. Thus, the connection terminal 10 is electrically connected to the conductor 41 by screwing another groove 57 to the screw portion 58 and screwing the groove 47 to the screw portion 48 of the bolt 46.

  After the groove 47 is screwed into the threaded portion 48 of the bolt 46, the knob 12 is bent using a clamping device. Specifically, the two clamping surfaces 13a and 13b are clamped by using a clamping device, and a force is applied in a direction in which the current-carrying body 30 is present. As a result, the bent portion 14 is plastically deformed, and the sandwiching portion 13 is bent in the direction in which the current-carrying body 30 is located with the bent portion 14 as a fold. Therefore, since the length that the support portion 15 protrudes is shorter than the length that the protruding member 43 protrudes, the length that the knob 12 protrudes is shorter than the length that the protruding member 43 protrudes.

  After the handle 12 is bent, another cover portion 52 is screwed into the screw portion 45 of the cover portion 42. As described above, the fuse 1 is disposed on the fuse cover 2.

  Here, according to the fuse 1 of the present embodiment, the connection terminal 10 has a substantially plate shape, and the connection terminal 10 has a knob 12 protruding from one surface 10a in a direction substantially perpendicular to the surface 10a. To have. Therefore, the maintenance staff can electrically connect the connection terminal 10 to the conductor 41 without directly touching the charging portion as in the prior art by holding the knob 12 with an insulating holding device. Therefore, an electric shock accident can be prevented, and the safety of the work of disposing the fuse on the lead-in wire can be further improved.

  In addition, according to the fuse 1 of the present embodiment, the knob 12 is disposed in the vicinity of the position where the connection terminal 10 and the electric current body 30 are connected. Accordingly, when the connection terminal 10 is electrically connected to the conductor 41, the possibility that the holding tool is caught by the connection terminal 10 can be reduced, and as a result, the connection can be made with less effort. In addition, the connection time can be shortened.

  Moreover, according to the fuse 1 of this embodiment, the knob 12 has the substantially plate-shaped clamping part 13 clamped using a clamping tool. Thereby, since the burden which clamps the knob 12 using a clamping tool is reduced, the time which electrically connects the connection terminal 10 to the conductor 41 can be shortened. In addition, since the possibility of accidentally directly touching the charging unit is reduced, it can be expected that the safety of the work of arranging the fuse on the lead-in wire is further improved.

  Moreover, according to the fuse 1 of this embodiment, the clamping part 13 has two clamping surfaces 13a and 13b parallel to each other. Thereby, since the burden which clamps the knob 12 using a clamping tool is reduced, the time which electrically connects the connection terminal 10 to the conductor 41 can be shortened. In addition, since the possibility of accidentally directly touching the charging unit is reduced, it can be expected that the safety of the work of disposing the fuse 1 on the lead-in wire is further increased. In addition, the connection terminal 10 is arranged on the one short side 30a side of the energizing body 30, and the two sandwiching surfaces 13a and 13b and the one short side 30a of the energizing body 30 are arranged so as to be parallel to each other. Yes. Thereby, when electrically connecting the connection terminal 10 to the conductor 41, it is possible to reduce the possibility that the holding device is caught by another member, and as a result, it is possible to connect with less labor. In addition, the connection time is further shortened.

  Further, according to the fuse 1 of the present embodiment, the knob 12 is constituted by the clamping part 13, the bent part 14, and the support part 15. The bent portion 14 is disposed between the sandwiching portion 13 and the support portion 15. Therefore, by bending the holding portion 13 with the bent portion 14 as a fold, the length that the knob 12 protrudes from the one surface 10a of the connection terminal 10 in a direction substantially perpendicular to the one surface 10a is set to the support portion. The length can be reduced to a length at which 15 protrudes. This facilitates the work of covering the fuse disposed on the lead-in wire with the fuse cover. Therefore, the entire work time can be further shortened.

  Further, according to the fuse 1 of the present embodiment, the bent portion 14 is formed to be recessed from the sandwiching portion 13 and the support portion 15. As a result, the bent portion 14 is plastically deformed with a weaker force than the sandwiching portion 13 and the support portion 15, so that the knob 12 is substantially perpendicular to the one surface 10 a from one surface 10 a of the connection terminal 10. The time for reducing the length protruding in the direction to the length protruding by the support portion 15 is further shortened. Therefore, the operation of screwing another cover portion 52 of the fuse cover 2 into the screw portion 45 of the cover portion 42 of the fuse cover 2 is further facilitated, and as a result, the working time can be further shortened.

  Further, according to the fuse 1 of the present embodiment, the protruding member 43 protrudes in the substantially same direction as the direction in which the knob 12 protrudes. Further, the length that the knob 12 protrudes is longer than the length that the protruding member 43 protrudes. As a result, even if the maintenance staff uses the clamping device, the gripper 12 can be clamped at a position where the clamping device does not catch on the protruding member 43. As a result, the connection terminal 10 can be electrically connected to the conductor 41 with less labor. Can be connected. In addition, the connection time can be shortened.

  Further, according to the fuse 1 of the present embodiment, the length that the knob 12 protrudes is longer than the length that the protrusion member 43 protrudes, but the length that the support portion 15 protrudes is that the protrusion member 43 protrudes. Shorter than length. Therefore, by bending the holding portion 13 with the bent portion 14 as a fold, the length that the knob 12 protrudes from the one surface 10a of the connection terminal 10 in a direction substantially perpendicular to the one surface 10a is set as a protruding member. It can be made shorter than the length by which 43 protrudes. As a result, the work of covering the fuse disposed on the lead-in wire with the fuse cover, specifically, the work of screwing another cover portion 52 of the fuse cover 2 to the screw portion 45 of the cover portion 42 of the fuse cover 2 is further performed. It becomes easier to do. Therefore, the entire work time can be further shortened.

  Further, according to the fuse 1 of the present embodiment, the knob 12 is formed of an insulator. Thereby, an electric shock accident can be prevented and the safety | security of the operation | work which arrange | positions the fuse 1 to a lead-in wire can further be improved. Moreover, the safety | security of the operation | work which arrange | positions the fuse 1 to a lead-in wire can be improved further by using together the protective tool for insulation conventionally used, and the insulated clamping tool.

  Further, according to the fuse 1 of the present embodiment, the connection terminal 10 has a substantially plate shape, and the connection terminal 10 has a knob 12 protruding from one surface 10a in a direction substantially perpendicular to the surface 10a. I am going to do that. Further, the shape of another connection terminal 20 is a substantially plate shape, and the other connection terminal 20 has another knob 22 protruding from one surface 20a in a direction substantially perpendicular to the surface 20a. As a result, the maintenance staff holds another connection terminal 20 on another conductor 51 without directly touching the charging part as in the prior art by holding another knob 22 using an insulating holding device. Can be connected electrically. Further, by holding the knob 12 with an insulating clamping device, the connection terminal 10 can be electrically connected to the conductor 41 without directly touching the charging portion as in the conventional case. Therefore, an electric shock accident can be prevented, and the safety of the work of disposing the fuse on the lead-in wire can be further improved.

  Moreover, according to the fuse 1 of this embodiment, the opening part 11 of the connection terminal 10 and the opening part 21 of another connection terminal 20 are arrange | positioned so that it may open in a mutually different direction. At this time, the two clamping surfaces 13a and 13b of the clamping unit 13, the two other clamping surfaces 13a and 13b of another clamping unit, and the one short side 30a of the current-carrying body 30 are arranged in parallel to each other. ing. Thereby, since the wide holding surfaces 13a, 13b, 23a, and 23b can be provided regardless of the direction in which the opening 11 and the other opening 21 are opened, the connection terminal 10 is electrically connected to the conductor 41. Since it is possible to reduce the risk of the tool being caught by the connection terminal 10, the connection terminal 10 and the other connection terminal 20 can be connected to the conductor 41 and the other conductor 51 with less effort as a result. In addition, the connection time can be shortened.

  Moreover, according to the fuse 1 of this embodiment, the opening part 11 of the connection terminal 10 and the opening part 21 of another connection terminal 20 are arrange | positioned so that it may open in a mutually different direction. At this time, the knob 12 and the other connection terminal 20 have different identification means and different identification means, respectively. Thereby, since the worker can grasp the direction in which the opening 11 and the other opening 21 are opened by the identification means and the other identification means, the time for confirming whether the connection terminal 10 is another connection terminal 20 or not. As a result, the connection time can be shortened.

  Further, according to the fuse 1 of the present embodiment, the identifying means is that the knob 12 is colored with the first color, and the other identifying means is that the other knob 22 is colored with the second color. It is colored. Thereby, the worker can grasp the direction in which the opening 11 and the other opening 21 open based on the difference in color, and as a result, it is possible to shorten the time for connection.

Furthermore, since the detachable member 3 can be attached to a known fuse that has been conventionally used, there is flexibility in the field where the fuse is disposed on the lead-in wire.

[Third Embodiment]
Hereinafter, the attaching / detaching device 4 according to the third embodiment of the present invention, which is used for a known fuse similar to the second embodiment, will be described.

  FIG. 7 is a schematic cross-sectional view of the attachment / detachment device 4. The attachment / detachment device 4 is in contact with an L-shaped L-shaped member 90 that comes into contact with one surface 30c (described later in FIG. 8) of the current-carrying body 30, and the other surface 30d (described later in FIG. 8). And another L-shaped member 100 having an L-shape. These L-shaped member 90 and another L-shaped member 100 are both formed of insulating members.

  The L-shaped member 90 includes a substantially plate-shaped current-carrying member contact portion 91, and this current-carrying member contact portion 91 has a contact surface 91a that contacts one surface 30c of the current-carrying member. The L-shaped member 90 is disposed along one side (not shown) of the current-carrying member contact portion 91, and includes a substantially plate-like support portion 92 that extends from the contact surface 91a in a direction substantially perpendicular to the contact surface 91a. Furthermore, it is comprised.

  Another L-shaped member 100 is configured to include another current-carrying member contact portion 101 having a substantially plate shape, and this another current-carrying member contact portion 101 is another contact surface that contacts the other surface 30 d of the current-carrying body 30. 101a.

  FIG. 8 is a schematic cross-sectional view when the attachment / detachment device 4 is attached to a known fuse. In the present embodiment, the support portion 92 has a sliding surface 92 a that slides another support portion 102. Thereby, the space | interval between the contact surface 91a and another contact surface 101a can be changed. Accordingly, the current-carrying body 30 is inserted between the contact surface 91a and the other contact surface 101a by making the distance between the contact surface 91a and the other contact surface 101a longer than the length of the current-carrying body 30 in the thickness direction.

  As described above, the attachment / detachment device 4 is attached to a known fuse (particularly, the attachment / detachment device 4 is attached to substantially the center of the current-carrying body 30), thereby obtaining substantially the same effect as the fuse 1 shown in FIG. Can do. Furthermore, since the attachment / detachment device 4 can be attached to a known fuse that has been conventionally used, there is flexibility in the field where the fuse is disposed on the lead-in wire.

  It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements and the like within the scope that can achieve the object of the present invention are included in the present invention.

  For example, the bent portion 14 is formed to be recessed with respect to the sandwiching portion 13 and the support portion 15, but is not limited thereto, and the member of the bent portion 14 is a member of the sandwiching portion 13 and the support portion 15. A softer member may be used. As a result, the bent portion 14 is plastically deformed with a weaker force than the sandwiching portion 13 and the support portion 15, so that the knob 12 is substantially perpendicular to the one surface 10 a from one surface 10 a of the connection terminal 10. The time for reducing the length protruding in the direction to the length protruding by the support portion 15 is further shortened. Therefore, it becomes easy to perform an operation of screwing another cover portion 52 of the fuse cover 2 into the screw portion 45 of the cover portion 42 of the fuse cover 2, and as a result, the entire working time can be further shortened.

  In the present embodiment, the identification means is to color the knob 12 with the first color, and the other identification means is to color another knob 22 with the second color different from the first color. However, it is not limited to this. For example, the discriminating means is that an arrow pointing in substantially the same direction as the opening of the opening 11 is imprinted on the knob 12, and the other discriminating means is substantially the same as the direction in which the other opening 21 opens. Another arrow pointing in the same direction may be stamped on another knob 22. Thereby, since the worker can grasp the direction in which the opening 11 and the other opening 21 open in the direction of the engraved arrow, it is possible to shorten the connection time as a result. A combination of a color and an arrow may be used as the identification unit. This makes it easier to grasp the opening direction.

  In the present embodiment, the bent portion 14 of the knob 12 is provided at one place between the sandwiching portion 13 and the support portion 15, but is not limited thereto. For example, the bent portion 14 may be further provided not only between the sandwiching portion 13 and the support portion 15 but also in the sandwiching portion 13 itself. Thereby, even if the length of the knob 12 protruding from the one surface 10 a of the connection terminal 10 is further increased, the other cover portion 52 can be reliably screwed into the screw portion 45 of the cover portion 42. Therefore, the workability at the site where the fuse is disposed on the lead-in wire is further enhanced.

  In the present embodiment, the knob 61 of the detachable member 3 is composed of the clamping part 62 and the bent part 63, but is not limited to this. For example, a configuration including only the clamping unit 62 may be used. Thereby, since the operation | work which bends the clamping part 62 in the direction of the sliding part 60 with a clamping member can be abbreviate | omitted, the workability | operativity in the field which arrange | positions a fuse to a lead-in wire further increases. In this case, after the fuse is disposed on the lead-in wire, the detachable member 3 needs to be removed from the connection terminal 10 before the other cover portion 52 is securely screwed into the screw portion 45 of the cover portion 42.
