  By the way, since the helical bind wire 80 is wound along the peripheral surface of the cable C, workability is poor. Further, when the bind wire 80 is wound, the bind wire 80 and the peripheral surface of the cable C are rubbed, so that there is a problem that the insulation coating of the cable C is damaged by the bind wire 80.

  Then, an object of this invention is to provide the cable support tool which makes it possible to support a cable efficiently to a pin insulator, without damaging a cable in view of the said problem.

  The cable support according to the present invention includes a pin insulator mounting portion formed so as to be fitted to the pin insulator from the radially outer side of the pin insulator, and a pair of cable fixings connected to both ends of the pin insulator mounting portion. A pair of cables formed on both sides of the pin insulator in a direction perpendicular to the axis of the pin insulator so as to be fitted from the outside in the radial direction of the cable and to be able to sandwich the cable. Cable fixing part.

  According to such a configuration, the entire cable support can be temporarily fixed to the pin insulator by fitting the pin insulator attachment portion into the pin insulator from the radially outer side of the pin insulator. Further, the cable can be fixed by being inserted into the cable extending on both sides of the pin insulator in a direction orthogonal to the axis of the pin insulator and then sandwiched after being fitted from the outside in the radial direction of the cable. That is, the cable is supported by the pin insulator through the cable support fixed to the pin insulator.

  Since the pair of cable fixing portions are fitted from the outside in the radial direction of the cable to fix the cable, winding work with a wire is not necessary, workability is improved, and damage to the cable due to winding can be prevented.

  As one aspect of the cable support according to the present invention, it is preferable that the fitting direction of the pin lever attachment portion with respect to the pin lever and the fitting direction of the cable fixing portion with respect to the cable are the same.

  According to such a configuration, since the fitting direction of the pin lever mounting portion with respect to the pin lever is the same as the fitting direction of the cable fixing portion with respect to the cable, the fitting into the pin lever and the fitting into the cable are smoothly performed. Workability is improved.

  As another aspect of the cable support according to the present invention, the pin insulator mounting portion is formed in an arc shape so as to be fitted in a region wider than a half circumference of the pin insulator, and between both ends of the arc-shaped portion. It is preferable that a fitting portion through which the pin insulator is passed is formed, and the fitting portion is narrower than the outer diameter of the pin insulator.

  According to such a configuration, the fitting portion is formed to be curved in an arc shape so as to be fitted in a region wider than a half circumference of the pin insulator, and the fitting portion for allowing the pin insulator to pass between both ends of the arc-shaped portion is formed. Therefore, the pin insulator mounting portion can be fitted into the pin insulator. In addition, since the fitting portion through which the pin insulator passes between both ends of the arcuate portion is narrower than the outer diameter of the pin insulator, the pin insulator mounting portion is not pinned unless the fitting portion is larger than the outer diameter of the pin insulator. I can't get out of Choshi. Therefore, even if the cable is swung by the wind, the pin insulator mounting portion can maintain the state of being fitted into the pin insulator.

  As another aspect of the cable support according to the present invention, the cable fixing portion includes a fixed-side holding portion that receives a cable, a support portion provided at a position facing the fixed-side holding portion, and a fixed-side holding portion. A movable body holding portion disposed at a position opposite to the fixed-side holding portion and movably provided between the fixed-side holding portion and the supporting portion. A movable holding portion that is attached to the support portion of the main body, and an operating mechanism portion that contacts and separates the movable holding portion from the fixed holding portion by an external operation. .

  According to such a configuration, since the cable received by the fixed-side holding unit is held between the fixed-side holding unit and the movable-side holding unit, the work efficiency can be improved because it is not a wire winding work. Further, since the cable is clamped by surface contact between the fixed-side clamping unit and the movable-side clamping unit, the cable is not damaged.

  Moreover, as another aspect of the cable support according to the present invention, it is preferable that the pin insulator mounting portion is formed by arranging a plurality of wire rods that are curved in an arc shape in a parallel state or a cross state.

  According to such a configuration, since a plurality of wire rods that are curved in an arc shape are fitted into the pin insulator, the force of each wire rod acts on the pin insulator, and the pin insulator attachment portion with respect to the pin insulator Can be firmly fixed.

  In addition, since a plurality of wire rods formed in an arc shape are arranged in a parallel state or a cross state, a contact area with the pin insulator is increased, and the pin insulator attachment portion can be firmly fixed to the pin insulator.

  As described above, according to the present invention, the cable can be efficiently supported by the pin insulator without damaging the cable.

Moreover, the pin insulator attachment part 2 has the holding part 20 formed in the center part so as to protrude radially outward so that it can be held by the indirect hot wire operation rod. The wire constituting the pin insulator mounting portion 2 has a metal core and an insulating material covering the core.

  Each of the pair of cable fixing portions 3 and 3 has the same structure. Therefore, here, one of the pair will be described. The cable fixing portion 3 has a vise structure. Specifically, the cable C extending from both sides of the pin insulator 70 in a direction perpendicular to the axis of the pin insulator 70 can be fitted from the outside in the radial direction, and the cable C can be sandwiched. Formed.

  Specifically, as shown in FIG. 3, the cable fixing portion 3 includes a fixed side holding portion 31 that receives the cable C, a support portion 32 provided at a position facing the fixed side holding portion 31, and a fixed side holding portion. A main body 30 having a connecting portion 33 that connects the portion 31 and the support portion 32, and a movable side holding portion 4 disposed at a position facing the fixed side holding portion 31, the fixed side holding portion 31 and the support portion The movable side clamping part 4 provided between the movable part 32 and the operating mechanism part 5 attached to the support part 32. The movable side clamping part 4 is fixed to the fixed side clamping part 31 by an external operation. And an actuating mechanism portion 5 that is brought into contact with and separated from the actuator. The main body 30 of the cable fixing portion 3 is made of an insulating material.

  The fixed-side clamping unit 31 has an arc-shaped inner surface 31a that can come into contact with the peripheral surface of the cable C, and receives the cable C by the inner surface 31a.

  The support portion 32 has a screw hole 32a into which a male screw portion 50 of the operation mechanism portion 5 described later is screwed.

  The connecting portion 33 determines the interval between the fixed-side clamping portion 31 and the support portion 32. This space | interval is the distance which moves the movable side clamping part 4 to the position which can insert / remove the cable C from the opening 30a of the main body 30 mentioned later.

  The main body 30 has a C-shaped cross section as a whole. Specifically, each of the fixed-side clamping unit 31 and the support unit 32 has a curved shape, and the cable C can be fitted therein. In addition, one end of each of the fixed-side holding unit 31 and the support unit 32 is connected, and the other end of each other is opened, and the cable C is provided between the fixed-side holding unit 31 and the support unit 32, that is, the opening 30a. Can be inserted. The opening 30a is opened in the same direction as the fitting portion 2c of the pin insulator mounting portion 2.

  The movable side clamping part 4 is attached to the front end part 50b of the external thread part 50 of the operating mechanism part 5 to be described later, and has an arcuate inner surface 4a that can contact and separate from the peripheral surface of the cable C. The movable side clamping part 4 is produced with the material which has insulation.

  The operating mechanism portion 5 is a male screw portion 50 that is provided so as to be able to move by being screwed to the support portion 32. The base end portion 50 a is led out to the outside, and the distal end portion 50 b is introduced into the main body 30. A male screw part 50 and an operation part 51 connected to the base end part 50a of the male screw part 50 are provided.

  Further, the main body 30 has a pair of extending portions 310 and 320 extending from each of the end portion of the fixed-side clamping portion 31 and the end portion of the support portion 32 toward the other end portion. Each extending portion 310, 320 extends in the axial direction of the cable C. The pair of extending portions 310 and 320 are arranged at an interval from each other in the direction in which the fixed-side holding portion 31 and the support portion 32 are arranged, thereby defining an opening 30a of the main body 30 into which the cable C can be inserted and removed. .

  Next, a usage mode of the cable support according to the present embodiment will be described. First, the male screw part 50 of the operating mechanism part 5 is operated to move the movable side holding part 4 away from the fixed side holding part 31 from the opening 30a of the cable fixing part 3 to a position where the cable C can be inserted and removed.

  Then, the fitting portion 2c (between both ends 2a and 2b of the arc-shaped portion) of the pin lever mounting portion 2 formed in a circular arc shape in the annular recess 71 of the pin lever 70 is connected to the diameter of the pin lever 70. It fits in the area | region wider than the semicircle of the pin insulator 70 from the direction outer side. As a result, the cable support 1 is temporarily fixed to the pin insulator 70.

  In this state, one end 2 a and the other end 2 b of the pin insulator mounting portion 2 are located in the vicinity of the cable C extending in a direction orthogonal to the axis of the pin insulator 70. Further, the fitting portion 2c (interval L between both ends 2a, 2b) of the pin insulator mounting portion 2 is narrower than the diameter R of the annular recess 71 of the pin insulator 70 as shown in FIG.

  Therefore, unless the fitting portion 2c (interval L between both ends 2a, 2b) of the pin insulator mounting portion 2 is larger than the diameter R of the annular recess 71 of the pin insulator 70, the pin insulator mounting portion 2 is It does not come out of the annular recess 71. Thereby, even if the cable insulator C is swung by the wind, the pin insulator attachment portion 2 can maintain the state of being fitted in the pin insulator 70.

  Next, the openings 30a and 30a of the pair of cable fixing portions 3 and 3 are fitted from the outside in the radial direction to the cable C extending on both sides of the pin insulator 70 in a direction orthogonal to the axis of the pin insulator 70. The cable C is received by the inner surfaces 31a of the fixed-side clamping portions 31 and 31 of the cable fixing portions 3 and 3, respectively.

  At this time, since the fitting direction of the pin insulator mounting portion 2 with respect to the pin insulator 70 and the fitting direction of the cable fixing portion 3 with respect to the cable C are the same, the fitting into the pin insulator 70 and the fitting into the cable C are smoothly performed. Workability is improved.

  Next, the male screw portion 50 is tightened, and the movable side holding portion 4 is moved toward the cable C received by the fixed side holding portion 31, so that the peripheral surface of the cable C is movable with the inner surface 31a of the fixed side holding portion 31. It clamps with the arc-shaped inner surface 4a of the side clamping part 4. FIG.

  The peripheral surface of the cable C is clamped by surface contact between the inner surface 31 a of the fixed-side clamping unit 31 and the inner surface 4 a of the movable-side clamping unit 4. For this reason, winding work by a wire becomes unnecessary, workability is improved, and damage to the cable C due to winding can be prevented.

  As described above, according to the cable support according to the present invention, the cable C can be efficiently supported by the pin insulator 70 without damaging the cable C.

  The cable support according to the present invention can be variously modified without being limited to the above embodiment.

  For example, in the case of the above-described embodiment, the pin insulator mounting portion 2 is composed of a single wire, but as shown in FIG. 4, it is composed of two parallel wires 2A, 2A formed in a circular arc shape. You may make it comprise, and as shown in FIG. 5, you may make it comprise by the two wire 2B and 2B which cross | intersect.

  In the case of FIG.4 and FIG.5, since the several wire 2A, 2A, 2B, 2B formed by curving in the circular arc shape is inserted in the pin insulator 70, the force of each wire 2A, 2A, 2B, 2B is received. It comes to act on the pin insulator 70, and the pin insulator attachment portion 2 can be firmly fixed to the pin insulator 70.

  In addition, since the plurality of wires 2A, 2A, 2B, 2B formed in a circular arc shape are arranged in a parallel state or a cross state, the contact area with the pin insulator 70 is increased, and the pin insulator 70 is attached to the pin insulator 70. The part 2 can be firmly fixed.

  In the embodiment, the pin insulator mounting portion 2 is formed to be curved in an arc shape. However, the pin insulator attachment portion 2 may have a shape surrounding the annular recess 71 of the pin insulator 70, for example, a polygon.
