  By the way, the fuse is attached to a cutout (so-called box-shaped cutout) including a cutout main body portion in which an insertion hole for inserting a contact blade is formed and a cover portion for covering the insertion hole. Yes.

  The cutout has an accommodation recess for accommodating and holding the fuse cylinder in the cover portion, and the contact blade is inserted into the insertion hole as the insertion hole is covered with the cover portion holding the fuse cylinder in the accommodation recess. It is comprised so that it may be inserted in.

  However, as described above, the conventional tip tool is configured to hold the fuse cylinder in the holding portion, so that the fuse cylinder is arranged in the housing recess and held in the cover portion or is held in the cover portion. When removing the fuse cylinder from the housing recess, the clamping part interferes with the cover part, and it may be difficult to attach or detach the fuse to the cutout.

  Therefore, in view of such a situation, an object of the present invention is to provide a tip tool for an insulated Ytco that can easily perform the operation of attaching / detaching a fuse to / from a cutout.

  The tip tool for an insulated Yacht of the present invention is attached to an insulated Ytco having a pair of gripping portions configured to be able to contact and separate, and extends in a direction perpendicular to the cylindrical fuse cylinder and the central axis direction of the fuse cylinder.

  According to the tip tool for an insulating Yatco having the above configuration, the opposing surface has a pressing surface that presses the side surface of the contact blade in the contact / separation direction, and at least one of the clamping portions is continuous with the pressing surface. In addition, since the contact blade has a wall surface facing the side edge of the contact blade, even if the contact blade sandwiched by the pressing surface of the facing surface of the sandwiching portion in the contact / separation direction moves unintentionally, the contact blade The movement of the side edge is restricted by contacting the wall surface. Therefore, the tip tool can suppress a change in the posture of the fuse holding the contact blade.

You may make it have a 2nd wall surface facing the other side edge of a contact blade.

  According to this configuration, the first wall surface can be opposed to one side edge of the contact blade in the direction orthogonal to the contact / separation direction, and the second wall surface can be opposed to the other side edge of the contact blade. Even if the contact blade that has been moved moves, the change in the attitude of the fuse between the first wall surface and the second wall surface can be suppressed to a smaller range.

  Further, in the tip tool for an insulating jacket according to the present invention, each of the opposing surfaces of the pair of clamping parts includes the wall surface, and the opposing wall surface of the one clamping part is in a direction perpendicular to the contact / separation direction. One of the first wall surface facing one side edge of the contact blade or the second wall surface facing the other side edge of the contact blade in a direction orthogonal to the contact / separation direction, and holding the other The wall surface of the opposing surface in the section may have either the first wall surface or the second wall surface.

  Even in such a configuration, the first wall surface can be opposed to one side edge of the contact blade in the direction orthogonal to the contact / separation direction, and the second wall surface can be opposed to the other side edge of the contact blade. Even if the contact blade is moved, the change in the posture of the fuse can be suppressed to a smaller range between the first wall surface and the second wall surface.

  As described above, according to the present invention, it is possible to achieve an excellent effect that the operation of attaching and detaching the fuse to and from the cutout can be easily performed.

  The stay part 3 extends from the attaching / detaching part 2 in a direction orthogonal to the contact / separation direction in which the pair of gripping parts 80 contact / separate. The stay portion 3 is formed in a flat plate shape, and has a fixed surface 30 disposed so as to face the adjacent stay portion 3. The fixed surface 30 is formed to have the same or substantially the same size as the outer shape of the sandwiching portion 4.

  In addition, each fixed surface 30 extends from the detachable portion 2 so as to be parallel to each other in a state in which each clamping portion 4 is closest (a state in which the contact blade 61 is sandwiched by each clamping portion 4).

  As shown in FIGS. 1 and 2, the sandwiching portion 4 includes a facing surface 40 that is disposed toward the sandwiching portion 4 adjacent in the contact / separation direction, and is located on the opposite side of the facing surface 40 and is a stay portion. 3 (see FIG. 1).

  The facing surface 40 of each clamping part 4 is formed to have a shape along the outer shape of the contact blade 61. In the present embodiment, the placement concave portion 42 for arranging the contact blade 61 is formed on the facing surface 40, and the portion defining the placement concave portion 42 on the facing surface 40 is one side surface or the other side surface of the contact blade 61. The shape is formed along the both side edges of the contact blade 61 in a direction orthogonal to the contact / separation direction.

  Each clamping part 4 is demonstrated more concretely. The clamping part 4 which concerns on this embodiment is the pressing part 43 which presses the side surface of the contact blade 61 in the said contact / separation direction, and the press part 43 in the height direction (one direction orthogonal to the said contact / separation direction) of the clamping part 4. And a pair of wall portions 44 and 45 connected to both ends.

  The pressing part 43 has a pressing surface 430 arranged toward the pressing part 43 adjacent in the contact / separation direction. The pressing surface 430 is formed such that the length in the depth direction orthogonal to the contact / separation direction and the height direction is larger than the length of the contact blade 61 (amount of extension from the fuse cylinder 60). Yes. The pressing surface 430 is formed such that the length in the height direction is larger than the width of the contact blade 61.

  The pressing surface 430 of the pressing portion 43 in one clamping unit 4 abuts on one side surface of the contact blade 61, and the pressing surface 430 of the pressing unit 43 in the other clamping unit 4 abuts on the other side surface of the contact blade 61. Furthermore, the tip tool 1 according to the present embodiment is configured such that the distance between the pressing surfaces 430 in the state where the clamping portions 4 are closest to each other is smaller than the thickness of the contact blade 61.

  One wall portion 44 (hereinafter referred to as the first wall portion 44) is formed such that the thickness in the contact / separation direction is larger than the thickness of the pressing portion 43. The first wall portion 44 is formed so that the length in the depth direction is the same as the length of the pressing portion 43.

  Further, the first wall portion 44 is connected to the wall surface (hereinafter referred to as a first wall surface) 440 that is continuous with one end of the pressing surface 430 in the height direction, and the first wall surface 440 is connected to and separated from the first wall surface 440. And a mating surface (hereinafter referred to as a first mating surface) 441 disposed toward the first wall portions 44 adjacent in the direction.

  The first wall surface 440 is formed so as to be orthogonal to the pressing surface 430. The length of the first wall surface 440 in the depth direction is the same as the length of the pressing surface 430. The first wall surface 440 is a surface opposed to one side edge (one side edge in the height direction) of the contact blade 61 sandwiched between the pressing surfaces 430.

  The other wall portion 45 (hereinafter referred to as the second wall portion 45) is formed such that the thickness in the contact / separation direction is larger than the thickness of the pressing portion 43. Further, the second wall portion 45 is formed so that the length in the depth direction is the same as the length of the pressing portion 43.

  Further, the second wall portion 45 is continuous with the wall surface 450 (hereinafter referred to as a second wall surface) 450 that is continuous with the other end of the pressing surface 430 in the height direction and the second wall surface 450, and And a mating surface (hereinafter, referred to as a second mating surface) 451 disposed toward the second wall portion 45 adjacent in the separating direction.

  The second wall surface 450 is formed to be orthogonal to the pressing surface 430. The length of the second wall surface 450 in the depth direction is the same as the length of the pressing surface 430. The second wall surface 450 is a surface that faces the other side edge (the other side edge in the height direction) of the contact blade 61 sandwiched between the pressing surfaces 430.

  The second wall surface 450 faces the first wall surface 440 in the height direction. Further, as described above, since the length of the pressing surface 430 in the height direction is larger than the width of the contact blade 61, the distance between the second wall surface 450 and the first wall surface 440 is larger than the width of the contact blade 61. Is also getting bigger.

  In the present embodiment, the opposing surface 40 includes a pressing surface 430 of the pressing portion 43, a first wall surface 440 and a first mating surface 441 of the first wall portion 44, and a second wall portion 45. A second wall surface 450 and a second mating surface 451 are included. The arrangement recess 42 is defined by the pressing surface 430 of the pressing portion 43, the first wall surface 440 of the first wall portion 44, and the second wall surface 450 of the second wall portion 45.

  The hook part 5 is formed in a rod shape. Moreover, the hook part 5 is arrange | positioned in the position (position which does not respond | correspond to the clamping part 4) from the clamping part 4 in the said depth direction.

  The tip tool 1 according to this embodiment is configured as described above. Next, the usage method of the tip tool 1 which concerns on this embodiment is demonstrated with reference to drawings.

  When using the tip tool 1, as shown in FIGS. 4 and 5, the gripping portion 80 of the insulating jacket 8 is inserted into the insertion recess 200 of the detachable portion 2, and the retaining portion 21 prevents the gripping portion 80 from coming off. .

  When the fuse 6 is attached to the cutout 7, the cover portion 71 of the cutout 7 is opened. In the present embodiment, the hook portion 5 is inserted into the hooking hole 720 of the operation piece 72, and the operation piece 72 is pulled down to open the cover portion 71.

  And after arrange | positioning the contact blade 61 between the press surfaces 430 of each clamping part 4, the operation lever 82 is operated and the holding parts 80 are made to approach, and the both sides | surfaces of the contact blade 61 are clamped by the press surface 430. As described above, since the interval between the pressing surfaces 430 of each clamping unit 4 is slightly smaller than the thickness of the contact blade 61, each pressing surface 430 sandwiches both side surfaces of the contact blade 61. A slight elastic deformation occurs along the outer shape of the contact blade 61. Further, in a state where both side surfaces of the contact blade 61 are sandwiched between the pressing surfaces 430, the second wall surface 450 and the other side edge of the contact blade 61 are between the first wall surface 440 and one side edge of the contact blade 61. A gap is formed between each of them. In this way, the fuse 6 is clamped by the tip tool 1.

  Further, the insulating cylinder 8 is moved to place the fuse cylinder 60 in the housing recess 710 of the cover portion 71. In this state, by operating the operating lever 82 to separate the gripping portions 80 from each other, the sandwiching of the contact blade 61 with both side surfaces by the pressing surface 430 is released. Thereby, the clamping with respect to the fuse 6 (contact blade 61) by the front-end tool 1 is released.

  Then, the hook portion 5 is inserted into the hooking hole 720 of the operation piece 72 and the operation piece 72 is pushed up to close the cover portion 71. Along with this, the contact blade 61 of the fuse 6 is inserted into the insertion recess 200, whereby the mounting operation of the fuse 6 to the cutout 7 is completed.

  When removing the fuse 6 from the cutout 7, the hook portion 5 is inserted into the hooking hole 720 of the operation piece 72, the operation piece 72 is pulled down, and the cover portion 71 is opened again.

  Then, the insulating yoke 8 is moved so that the pressing surfaces 430 are opposed to both side surfaces of the contact blade 61 of the fuse 6 accommodated in the accommodating recess 710. In this state, when the operation lever 82 is operated to bring the gripping portions 80 closer to each other and the both side surfaces of the contact blade 61 are sandwiched between the pressing surfaces 430, the fuse 6 is sandwiched by the tip tool 1. In addition, although each clamping part 4 has elasticity, since it is attached to the stay part 3 having rigidity as described above, a sufficient clamping force is transmitted from the clamping part 4 to the contact blade 61.

  By further moving the insulating jacket 8 and pulling out the fuse cylinder 60 from the collecting recess, the fuse 6 is removed from the cutout 7, and the work for removing the fuse 6 from the cutout 7 is completed.

  As described above, according to the tip tool 1 according to the present embodiment, since the contact blade 61 of the fuse 6 is configured to be clamped by the facing surface 40, the clamp 6 is clamped when the fuse 6 is attached to or detached from the cutout 7. It can suppress that the part 4 interferes with the cutout 7. FIG. Therefore, the tip tool 1 can have an excellent effect that the work of attaching / detaching the fuse 6 to / from the cutout 7 can be easily performed.

  Moreover, since the opposing surface 40 of the clamping part 4 is a shape along the external shape of the contact blade 61, it can suppress that the contact blade 61 currently clamped by the opposing surface 40 moves. Therefore, the tip tool 1 can stabilize the posture of the fuse 6 holding the contact blade 61 between the opposing surfaces 40.

  More specifically, each clamping part 4 has a first wall 44 that faces one side edge of the contact blade 61, and each second clamping wall 4 has a second wall that faces the other side edge of the contact blade 61. Therefore, even if the contact blade 61 sandwiched between the pressing surfaces 430 moves in the contact / separation direction, the contact blade 61 moves to the first wall portion 44 (first wall surface 440) or The movement is restricted by coming into contact with the second wall 45 (second wall surface 450). Therefore, the tip tool 1 can suppress the range in which the posture of the fuse 6 holding the contact blade 61 changes.

  Moreover, since the space | interval of the pressing surfaces 430 of each clamping part 4 in the state which made each clamping part 4 approached most is slightly smaller than the thickness of the contact blade 61, each press surface 430 is the contact blade 61 of the contact blade 61. As both side surfaces are sandwiched, the elastic deformation slightly occurs along the outer shape of the contact blade 61. Thereby, the adhesiveness of the press surface 430 and the side surface of the contact blade 61 is improved. Therefore, the tip tool 1 according to the present embodiment can further stabilize the posture of the fuse 6 held by the holding unit 4.

  Further, since the distance between the first wall surface 440 and the second wall surface 450 (the length of the pressing surface 430 in the height direction) is larger than the width of the contact blade 61, the pressing surface 430 makes contact. It is possible to prevent the first wall surface 440 and the second wall surface 450 from interfering with the contact blade 61 when the blade 61 is sandwiched or when the pressing surface 430 is released from the contact blade 61. Therefore, in the tip tool 1 according to the present embodiment, the contact blade 61 can be easily held and released from the contact blade 61 at a timing intended by the operator.

  The tip tool of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications are made without departing from the gist of the present invention.

  In the said embodiment, although the attachment surface 41 of the clamping part 4 was attached to the stay part 3, it is not limited to this structure. For example, the attachment surface 41 of the clamping part 4 may be directly attached to the attachment / detachment part 2. That is, the clamping part 4 should just be attached to the attachment / detachment part 2 directly or indirectly.

  In the above-described embodiment, the arrangement recess 42 is formed on each facing surface 40 of each clamping unit 4, but is not limited to this configuration. For example, the arrangement recess 42 may be formed on the facing surface 40 of one of the pair of sandwiching portions 4. In other words, the arrangement recess 42 only needs to be formed in at least one of the pair of sandwiching portions 4.

  In the said embodiment, in each clamping part 4, the opposing surface 40 was a shape along the one side surface or other side surface of the contact blade 61, and the both-sides edge of the contact blade 61 in the direction orthogonal to the said contact / separation direction. However, it is not limited to this configuration. For example, in each clamping part 4, the opposing surface 40 may be comprised with the flat surface as a whole.

  Moreover, in each clamping part 4, the opposing surface 40 is along any one side edge of the one side surface or other side surface of the contact blade 61, and the both-sides edge of the contact blade 61 in the direction orthogonal to the said contact / separation direction. The shape may be different. That is, the shape along the outer shape of the contact blade of the facing surface 40 is a shape that can cover one side surface or the other side surface and a corner that is continuous with one of the one side surface or the other side surface.

  In the said embodiment, although each clamping part 4 had a wall part with thickness larger than the press part 43, it is not limited to this structure. For example, only one of the pair of sandwiching portions 4 may have a wall portion. In this case, it is preferable that the wall surfaces are opposed to both side edges of the contact blade 61 in a direction orthogonal to the contact / separation direction. More specifically, the pair of wall portions 44 and 45 that only one of the pair of sandwiching portions 4 has is a pair of walls that are connected to both ends of the pressing portion 43 in the height direction. The wall portions 44 and 45 are preferably provided.

  In the above-described embodiment, the pressing portion 43 has the first wall portion 44 connected to one end in the height direction and the second wall portion 45 connected to the other end in the height direction. The configuration is not limited to this. For example, the pressing portion 43 may be provided with a wall portion only at one end or the other end in the height direction. In this case as well, it is preferable that the wall face be opposed to both side edges of the contact blade 61 in the direction orthogonal to the contact / separation direction. More specifically, for example, a wall provided in any one of the pair of holding parts 4 is a wall that is connected to one end of both ends of the pressing part 43 in the height direction. And the wall portion of any one of the pair of sandwiching portions 4 has a wall portion connected to the other end of both ends of the pressing portion 43 in the height direction. It is preferable.

  In the said embodiment, although the thickness in the said contact / separation direction of the 1st wall part 44 and the thickness in the said contact / separation direction of the 2nd wall part 45 became the same, it is not limited to this structure. The thickness of the first wall portion 44 in the contact / separation direction and the thickness of the second wall portion 45 in the contact / separation direction are parallel to one side surface or the other side surface of the contact blade 61. Each thickness may be different as long as it can be contacted in a proper posture. As described above, in the insulating Yatco 8, the pair of gripping portions 80 come in and out of contact with each other in the circumferential direction centered on the connection position (that is, move along an arcuate track centered on the connection position). For this reason, the interval between the second wall portions 45 tends to be smaller than the interval between the first wall portions 44 in the circumferential direction, and the second wall portions 45 are arranged before the first wall portion 44. May come into contact. Therefore, if the thickness of the second wall portion 45 is made smaller than the thickness of the first wall portion 44, only the second wall portion 45 comes into contact when the sandwiching portions 4 are brought closest to each other. Thus, the pressing surface 430 can be brought into contact with the one side surface or the other side surface of the contact blade 61 in a posture parallel to the contact blade 61 more reliably.
