Insulation treatment is performed. When such an insulation process is performed by indirect hot wire work, an insulated wire repair cover corresponding to the indirect hot wire work is used.

  The insulated wire repair cover corresponding to the indirect hot wire operation includes a pair of cover constituent members having a substantially semi-cylindrical shape. The cover constituent members are connected to each other so as to be rotatable at one of the semi-cylindrical end portions of the semi-cylindrical shape formed by the cover constituent members. A claw is formed at the other end in the diameter direction of one cover constituent member of the pair of cover constituent members, and the other end in the diameter direction of the other cover constituent member is at a position corresponding to the claw. A recess is formed. A plurality of (for example, three) claws and recesses are provided along the length direction of the cover constituent member. In addition, one cover component member is provided with a gripping portion that receives gripping by an indirect hot wire tool such as an insulating jacket.

  Exemplary embodiments of a cover mounting jig according to the present invention will be described below in detail with reference to the accompanying drawings.

<Embodiment 1>
First, the configuration of the cover mounting jig according to the first embodiment of the present invention will be described. 1-3 is explanatory drawing which shows the structure of the cover attachment jig | tool of Embodiment 1 concerning this invention.

  As shown in FIGS. 1 to 3, the cover mounting jig 100 according to the first embodiment of the present invention includes a support member 110, a connection fitting 120, and a pair of pressure members 130. The support member 110 has a flat plate shape and supports the connection fitting 120 and the pair of pressure members 130. The connection fitting 120 and the pair of pressure members 130 are provided on the same surface of the support member 110.

  The connection fitting 120 has a cylindrical shape, and is fixed to the support member 110 on one end side in the axial direction. The connection fitting 120 includes a joint portion 121 having a substantially cylindrical shape including a shaft hole that fits with the tip of a common operation rod (see reference numeral 600 in FIG. 6) on the other end side in the axial direction.

  In the connection fitting 120, a groove 122 having a substantially T-shape is provided on the outer peripheral surface of the joint portion 121 so as to be continuous with the periphery of the shaft hole. The groove 122 constitutes a twist lock structure that fixes the coupling fitting 120 to the tip of the common operation rod by engaging with a pin provided at the tip of the common operation rod. Since the twist lock structure is a known technique, description thereof is omitted.

  Each of the pair of pressure members 130 includes a pressure surface 131. The pair of pressure members 130 are arranged such that the pressure surfaces 131 face each other with a predetermined interval. Each of the pressure surfaces 131 provided in the pair of pressure members 130 is such that both end sides of the space formed between the pair of pressure members 130 are narrower than the center side in the thickness direction of the support member 110. It has a curved bow shape.

  Specifically, the pressure member 130 can be realized by, for example, a columnar body having a drum shape whose diameter dimension is larger at both ends in the axial direction than at the center. In this case, the pressing surface 131 can be realized by the outer peripheral surface of the columnar body. As a result, the cover mounting jig 100 can be assembled with the pressing surfaces 131 facing each other simply by attaching the pressing member 130 to the support member 110 so that the axial directions of the columnar bodies are parallel.

Specifically, a through hole (not shown) is provided along the axis of the columnar body that realizes the pressure member 130, a through hole that penetrates in the thickness direction is provided in the support member 110, and each through hole is penetrated. By screwing the nut 201 into the bolt 132 inserted as described above, the pair of pressure members 130 can be provided to be rotatable around the axis.

(Insulated wire repair cover configuration)
Next, the configuration of the insulated wire repair cover to be attached using the cover attachment jig 100 will be described. FIG. 4 is an explanatory diagram showing the configuration of the insulated wire repair cover. As shown in FIG. 4, the insulated wire repair cover 400 includes a pair of cover constituent members 401 and 402 having a substantially semi-cylindrical shape, and forms a substantially columnar shape when combined.

  The cover constituent members are connected to each other so as to be rotatable at one end of the semicylindrical ends in the diametrical direction formed by the cover constituent members 401 and 402. One cover constituent member 401 of the pair of cover constituent members 401 and 402 includes a claw 403 formed at the other end in the diameter direction. In addition, one cover constituent member 401 includes a gripping portion 404 that receives gripping by an indirect hot wire tool such as an insulating Yatco (see reference numeral 500 in FIG. 5).

  The other cover constituent member 402 of the pair of cover constituent members 401 and 402 includes a recess 405 formed at the other end in the diametrical direction. A plurality of (for example, three) claws 403 and recesses 405 are provided along the length direction of the cover constituent members 401 and 402. The nail | claw 403 and the recessed part 405 are each provided in the position which opposes in the state which combined a pair of cover structural member 401,402.

  Thereby, the nail | claw 403 and the recessed part 405 can be directly opposed by combining a pair of cover structural member 401,402. Then, by fitting the claw 403 into the recess 405, the pair of cover components 401 and 402 can be held in a closed state so that the exposed conductive portion is covered with the insulated wire repair cover 400.

  A fusing material and a sealing material are provided inside each cover constituent member 401 and 402 (both are not shown). The fusing material prevents the insulated wire repair cover 400 attached to the insulated wires from moving along the insulated wires. The fusing material is provided on both end sides in the length direction of the cover constituent member. By providing the fusing material, it is possible to prevent the insulated wire repair cover 400 after being attached from being displaced from the attachment position.

  The sealing material insulates a conductive portion to be attached to the insulated wire repair cover 400 such as a joint portion where two wires are joined. The sealing material is provided on both ends in the length direction of the cover constituent member and on the inner side of the fusion material. By providing a sealing material inside each cover constituent member, it is possible to seal the conductive portion by attaching the insulated wire repair cover 400 and to ensure the waterproofness of the conductive portion. Further, by providing a seal material inside each cover constituent member, it is possible to eliminate the need for a taping process applied to the openings at both ends in the length direction of the insulated wire repair cover 400.

(Insulation wire repair cover 400 installation procedure)
Next, a procedure for mounting the insulated wire repair cover 400 using the cover mounting jig 100 according to the first embodiment of the present invention will be described. 5-7 is explanatory drawing which shows the attachment operation | movement procedure of the insulated wire repair cover 400 using the cover attachment jig | tool 100 of Embodiment 1 concerning this invention. When attaching the insulated wire repair cover 400, first, as shown in FIG. 5, the insulated wire repair cover 400 is subjected to insulation processing in the insulated wire 501 in a state in which the grip portion 404 is gripped by the insulated Ytco 500. Cover (conductive part).

  Next, as shown in FIG. 6, the cover mounting jig 100 is connected to the tip of the common operation rod 600. The common operation rod 600 includes a connector 602 provided with a pin 601 that protrudes in a plane orthogonal to the axial direction at the tip. The pin 601 is engaged with a substantially T-shaped groove 122 provided on the outer peripheral surface of the shaft hole portion in the connecting bracket 120 to constitute a twist lock structure, whereby the connecting tool 602 of the common operation rod 600 is provided. Can be connected to the front end of the common operation rod 600.

  Next, the cover attachment jig 100 is positioned on one end side in the length direction of the insulated wire repair cover 400 that covers the conductive portion of the insulated wire 501. At this time, the insulated wire 501 is positioned between the pair of pressure members 130. Then, as shown in FIG. 7, the cover mounting jig 100 is slid along the length direction of the wire insulated wire 501. As a result, the cover mounting jig 100 slides along the insulated wire repair cover 400 in a state where the insulated wire repair cover 400 is sandwiched between the pair of pressure members 130 from one end side in the length direction. To do.

  When the claws 403 provided at a plurality of locations (three locations) in the insulated wire repair cover 400 are positioned between the pair of pressure members 130, the claws 403 are fitted into the opposing recesses 405. The sliding movement of the cover mounting jig 100 may be reciprocated along the insulated wire repair cover 400. Thereby, the nail | claw 403 can be reliably engage | inserted in the recessed part 405. FIG.

  Since the pressurizing surface 131 has a curved bow shape, a space having a shape corresponding to the shape of the insulated wire repair cover 400 is formed between the pressurizing surfaces 131 in an opposed state. By sandwiching the insulated wire repair cover 400 between the pressure surfaces 131 and sliding, the deformation of the insulated wire repair cover 400 due to the sandwich is prevented, and the claw 403 is securely fitted in the recess 405. Can be included.

  Since the pair of pressure members 130 are rotatably provided, when the cover mounting jig 100 is slid, the pressure members 130 are rotated around the axis by friction with the insulated wire repair cover 400. Since the pressing member 130 is a columnar body having a drum shape with a constricted central side in the axial direction, the pressing surfaces 131 having a curved bow shape can always face each other regardless of the rotation angle. Thereby, the burden of the operator who slide-moves the cover attachment jig | tool 100 along the insulated wire repair cover 400 can be aimed at.

  In the cover mounting jig 100 described above, the pair of pressure members is realized by a pair of columnar bodies having a constricted drum shape at the center side in the axial direction, but the shape of the pressure member has a drum shape. It is not limited to a columnar body. For example, instead of the drum-shaped columnar body, a pair of pressure members may be realized by a pair of semi-cylindrical members. In this case, the pair of members having a semi-cylindrical shape are arranged at a predetermined interval with the concave surfaces facing each other. In this case, the position with respect to the support member 110 is fixed so that the semi-cylindrical member does not rotate.

  Thus, by using the shape of the inner surface curved in an arc shape in the semi-cylindrical member, both end sides are narrower than the center side along the plate thickness direction of the support member 110 between the pair of pressure members. Such a space can be formed. In this case, the semi-cylindrical member may have a shape in which both end sides in the axial direction are curved in directions away from each other. Thereby, even when the pair of pressure members does not rotate, the insulated wire repair cover 400 can be easily introduced between the pair of pressure members.

  Alternatively, a pair of pressure members may be realized by a pair of plate-like members having a substantially “<” shape instead of the drum-like columnar body. Alternatively, one of the pair of pressure members may be realized by a columnar body having a drum shape, and the other may be realized by a member having a semi-cylindrical shape or a plate-like member having a substantially “<” shape. Good.

  As described above, the cover mounting jig 100 according to the first embodiment of the present invention includes the pressure surfaces 131, and a pair of the pressure surfaces 131 arranged to face each other with a predetermined gap therebetween. The pressure member 130, the support member 110 that supports the pair of pressure members 130, and the connection fitting 120 that is provided on the support member 110 and that can be connected to the connection tool 602 provided at the tip of the common operation rod 600. It is characterized by having.

  According to the cover mounting jig 100 of the first embodiment of the present invention, a pair of pressure members having the insulated wire repair cover 400 sandwiched therebetween by moving the common operation rod 600 along the insulated wire 501. 130 can be slid along the insulated wire repair cover 400. When the claws 403 provided at a plurality of locations (three locations) in the insulated wire repair cover 400 are positioned between the pair of pressure members 130 as the pair of pressure members 130 slide. , And can be fitted into the opposing recess 405.

  In this manner, the claw 403 and the recesses 405 provided at a plurality of locations (three locations) in the insulated wire repair cover 400 can be easily achieved simply by sliding the cover mounting jig 100 along the insulated wire repair cover 400. And it can be surely fitted. Thereby, the nail | claw 403 and the recessed part 405 in the insulated wire repair cover 400 can be reliably joined, and the opening of the insulated wire repair cover 400 can be reliably prevented. And by reliably preventing the opening of the insulated wire repair cover 400, it is possible to reliably prevent the insulated wire repair cover 400 from dropping off after installation and exposing the charged portion, and the charged portion is exposed. It is possible to reliably prevent accidental power outages caused by

  In addition, since the fitting of the claw 403 and the recess 405 is not halfway, additional work such as re-inserting and taping can be eliminated. Thereby, the working efficiency can be improved, and the installation work of the insulated wire repair cover 400 can be speeded up.

The support member 110 supports the pair of pressure members 130 so that one of the ends is closed by making a bow shape so that the side is narrower than the center side.

  According to the cover mounting jig 100 according to the first embodiment of the present invention, the pressing surfaces 131 of the pair of pressing members 130 that slide along the axial direction of the cylindrical insulated wire repair cover 400 are provided. By adopting a shape that matches the shape of the insulated wire repair cover 400, the insulated wire repair cover 400 can be prevented from being deformed by being caught, and the claw 403 can be securely fitted into the recess 405.

  Further, in the cover mounting jig 100 according to the first embodiment of the present invention, the pair of pressure members 130 each have a columnar shape in which the diameter dimension is larger than the center side at both end sides in the axial direction. The support member 110 supports the pair of pressure members 130 in a state where the axial directions of the pair of pressure members 130 are parallel and the outer peripheral surfaces (pressure surfaces 131) face each other. It is characterized by that.

  According to the cover mounting jig 100 according to the first embodiment of the present invention, when the pressure member 130 is attached to the support member 110, the support member 110 is pressurized so that the axial directions of the columnar bodies are parallel to each other. By simply attaching the member 130, the cover mounting jig 100 can be assembled with the pressing surfaces 131 facing each other. Thereby, the manufacture of the cover mounting jig 100 can be facilitated. Further, by realizing the pressing member 130 with a columnar body, the cover mounting jig 100 can be downsized.

  Further, the cover mounting jig 100 according to the first embodiment of the present invention is characterized in that the pair of pressure members 130 can rotate about their respective axes.
