The winding grip 110 has a certain degree of rigidity, and can be bent by plastic deformation with a predetermined force. As shown in FIG. 2, the winding grip 110 includes a base end portion 111 bent in a curved shape, a pair of intermediate portions 113 extending linearly from both ends of the base end portion 111, and a straight line from the front end of each intermediate portion 113. And a pair of grip portions 115 that are wound around the wire W and hold the wire W. The winding grip 110 has a substantially symmetrical shape with the base end 111 as a boundary, and has rigidity that can be bent and deformed. The base end portion 111 is defined as a curved portion at a substantially central position of the entire winding grip 110. The intermediate portion 113 is defined as a straight portion having a predetermined length that is connected to both ends of the base end portion 111. The grip portion 115 is defined as a spiral portion that is connected to the tip of the intermediate portion 113. The pair of grip portions 115 have different lengths. Then, by inserting the wire W inside the spiral of one grip portion 115 and twisting the grip portions 115 together, the wire W can be securely gripped and supported or fixed by the pair of grip portions 115. is there.

  FIG. 3 is a schematic perspective view of the thimble 120. 4A to 4D are a plan view, a front view, a side view, and an AA sectional view of the thimble 12, respectively. The thimble 120 is a U-shaped metal piece in front view. As shown in FIGS. 3 and 4, the thimble 120 includes a curved arc-shaped portion 121 and a pair of straight-shaped portions 123 that extend linearly from both ends of the arc-shaped portion 121. The pair of straight portions 123 are inclined in the direction in which the tips approach each other. The thimble 120 has a continuous U-shape in cross-sectional view. That is, the thimble 120 has an outer peripheral concave portion 125 on the outer peripheral surface of the U shape when viewed from the front, and an inner peripheral convex portion 127 on the inner peripheral surface of the U shape when viewed from the front. In the outer peripheral recess 125 of the thimble 120, a groove that opens to the outside is continuously formed, and the base end portion 111 of the winding grip 110 can be accommodated in the groove. On the other hand, the connecting portion X1 (see FIGS. 7 and 8) of the support bar X in the branch line structure 10 is engaged with the inner peripheral convex portion 127 of the thimble 120. Then, the thimble 120 shows that the curvature of the base end portion 111 is excessively reduced when a tension is applied to the wire W in a state where the winding grip 110 (base end portion 111) is accommodated in the outer peripheral recess 125. It is configured with sufficient rigidity to prevent and maintain the base end portion 111 (eye portion) in a curved shape.

  The tube body 130 is configured in a cylindrical shape into which the winding grip 110 and the thimble 120 are inserted. In the wire end fixture 100 of the present embodiment, the tube body 130 is composed of a heat-shrinkable tube that is contracted and deformed by heat. That is, the tube body 130 is made of a general heat shrinkable tube made of polyolefin, fluorine-based polymer, thermoplastic elastomer or the like. The tube body 130 preferably includes a heat-shrinkable outer skin and an adhesive layer made of a hot-melt adhesive (ethylene vinyl acetate or the like) formed on the inner surface thereof. By the adhesive layer, the inner surface of the tube body 130 and the outer surfaces of the winding grip 110 and the thimble 120 can be bonded firmly and reliably. However, the tube body 130 may be composed only of a heat-shrinkable outer skin.

  FIG. 5 is a partially enlarged view of the wire end fixture 100 of FIG. As shown in FIG. 5, the tube body 130 integrally holds the winding grip 110 and the thimble 120 so that the outer periphery of the arc-shaped portion 121 is arranged along the inner periphery of the base end portion 111. In the present specification, “follow” and “attachment” include not only a state where they are in contact with each other or adjacent to each other, but also a state where they are separated from each other. The pair of straight portions 123 of the thimble 120 are inclined in the direction in which the tips approach each other, and only one of the pair of straight portions 123 is one of the pair of intermediate portions 113 of the winding grip 110 by the tube body 130. Are integrally coupled to the In the present embodiment, only one straight intermediate portion 113 of the winding grip 110 is integrally held by one straight portion 123 of the thimble 120. And although the base end part 111 and the arc-shaped part 121 and the other intermediate part 113 and the straight part 123 are mutually spaced apart, they are arranged close to each other so as to face each other.

  More specifically, the tube body 130 is wound around the winding grip 110 (intermediate portion 113) and the thimble 120 in a state where the intermediate portion 113 of the winding grip 110 is accommodated in the outer peripheral recess 125 of one straight portion 123 of the thimble 120. The polymerization part of (straight part 123) is surrounded. Since the overlapped portion is formed by the straight portions of the winding grip 110 and the thimble 120, it is easily surrounded by the tube body 130. Further, the tube body 130 extends across the tip of the straight portion 123 of the thimble 120. In other words, the tube body 130 surrounds the overlapped portion, extends from the overlapped portion beyond the tip end portion of the thimble 120 to the tip end side of the winding grip 110, and the intermediate portion 110 of the winding grip 110 at the tip end side of the boundary. Only besiege. Then, the tube body 130 shrinks and deforms following the outer surface shape of the winding grip 110 and the thimble 120 in a state where the overlap portion (whole or part) is inserted, and the shoulder portion 131 is at the boundary with the overlap portion. It is narrowed on the tip side so as to be formed. As described above, the distal end side of the tube body 130 is narrowed, so that the tube body 130 is strongly adsorbed (adhered) to the outer surfaces of the winding grip 110 and the thimble 120, and the winding grip 110 and the thimble 120 are displaced from each other. It is suppressed.

  Next, a method for manufacturing the wire end fixture 100 of the present embodiment will be described with reference to FIG. In addition, this method comprises a part of method of constructing the branch line structure 10, and the branch line structure 10 can be constructed through this method.

  First, the winding grip 110, the thimble 120, and the tube body 130 are prepared. Next, as shown in FIG. 6A, the tube body 130 is extrapolated from the tip of one of the grip portions 115 of the winding grip 110, and the tube body 130 is slid to the intermediate portion 113. Next, as shown in FIG. 6B, the outer periphery of the arcuate portion 121 of the thimble 120 is arranged along the inner periphery of the base end portion 111 of the winding grip 110, and the overlapping portion of the winding grip 110 and the thimble 120 ( A part or the whole is surrounded by the tube body 130. More specifically, the intermediate portion 113 is accommodated in the outer peripheral recess 125 of the straight portion 123 while the outer periphery of the arcuate portion 121 of the thimble 120 is opposed to the inner periphery of the base end portion 111 of the winding grip 110. The winding grip 110 and the thimble 120 are partially polymerized. And the tube body 130 is arrange | positioned so that it may straddle between the linear superposition | polymerization part and the intermediate part 113 single-piece | unit part at the front end side.

  Subsequently, the tube body 130 in a state where the overlapping portions of the winding grip 110 and the thimble 120 are inserted is heated with a heat gun or the like, and the tube body 130 is thermally contracted. As a result, as shown in FIG. 6C, the tube body 130 is deformed following the outer surface shape of the winding grip 110 and the thimble 120 and is adsorbed on the outer surface of the overlapped portion and the winding grip 110 alone. When a heat-meltable adhesive layer is provided on the inner surface of the tube body 130, the adhesive layer is melted together with the heat shrinkage of the outer skin by heating, and the space between the outer skin and the outer surfaces of the winding grip 110 and the thimble 120 is increased. Bonded more firmly with the adhesive layer. Thus, the wire end fixture 100 can be manufactured.

  With reference to FIG.7 and FIG.8, the branch line structure 10 constructed | assembled using the wire edge part fixing tool 100 of this embodiment is demonstrated. 7 and 8 are a schematic view showing the branch line structure 10 and a partially enlarged view thereof. The branch line structure 10 is constructed by obliquely stretching a wire W and a support bar X between an upper portion of a utility pole and an anchor embedded in the ground. For convenience of explanation, the utility pole and the underground anchor are not shown.

  In the branch line structure 10 of the present embodiment, one end of the wire W is fixed to the upper part of the utility pole, and one end of the support bar X is fixed to the underground anchor. The wire W is a wire formed by bundling steel materials, and has sufficient strength to support the utility pole. The support bar X is a steel bar material having sufficient rigidity to support the utility pole, and an annular coupling portion X1 is formed at the other end. As shown in FIGS. 7 and 8, the wire end fixture 100 fixes the wire W and the support rod X in a state where tension is applied. More specifically, the pair of grip portions 115 are twisted together in a state where the wire W is inserted inside the spiral of one grip portion 115 of the winding grip 110, so that the grip portion 115 becomes an end portion of the wire W. Is fixed. In addition, the grip portion 115 is twisted to form an eye portion at the base end portion 111. The thimble 120 accommodates the base end portion 111 (one end side of the eye portion) in the outer peripheral recess 125 in a state of being held integrally with the winding grip 110 by the tube body 130. And the winding grip 110 (base end part 111) and the thimble 120 are arrange | positioned inside the ring of the connection part X1 of the support rod X, and the internal peripheral convex part 125 of the arc-shaped part 121 of the thimble 120 is on the internal peripheral surface of the connection part X1. Engagement (pressure contact). In other words, the thimble 120 supports the connecting portion X1 of the support rod X. In the branch line structure 10, a strong tension acts on the wire W and the winding grip 110 is pressed against the thimble 120, so that the eye part of the winding grip 110 is deformed along the outer peripheral recess 125 of the thimble 120. The curvature of the arcuate portion 121 of the thimble 120 is maintained against the tension (some deformation is allowed), so that the curvature of the eye portion of the winding grip 110 is excessively reduced by the thimble 120. Is prevented.

  Hereinafter, the operation and effect of the wire end fixture 100 according to the embodiment of the present invention will be described.

  According to the wire end fixing tool 100 of the present embodiment, the tube body 130 is deformed following the outer surface shape of the winding grip 110 and the thimble 120 in a state where the overlapped portion of the winding grip 110 and the thimble 120 is inserted. As a result, it is possible to temporarily hold the winding grip 110 and the thimble 120 integrally with an extremely simple structure. Then, the inner periphery of the base end portion 111 of the winding grip 110 and the outer periphery of the arcuate portion 121 of the thimble 120 are attached to each other so as to be opposed to each other. The positioning of the thimble 120 with respect to the winding grip 110 can be omitted. More specifically, in the operation of fixing the wire W with the grip portion 115 or the operation of engaging the connecting portion X1 of the support rod X with the eye portion and the thimble 120 of the winding grip 110, the thimble 120 has the winding grip 110. Since it is temporarily held at the predetermined position, either one of the grip 110 and the thimble 120 may be gripped. Furthermore, since one straight portion 123 of the thimble 120 is integrated with one intermediate portion 113 of the winding grip 110, there is no gap between the tip of the thimble 120 and the intermediate portion 113, and the winding grip 110 is fastened. Even if the tool is annular, it can be easily inserted. As a result, the work burden on the installer can be greatly reduced. Furthermore, the possibility of the installer dropping the member can be prevented beforehand.

  Moreover, according to the wire end fixing tool 100 of the present embodiment, the tube body 130 is formed of a heat shrinkable tube. In other words, the tube body 130 is contracted from the original shape by heat. That is, the tube body 130 is heated and contracted in a state in which at least a part of the overlapping portion of the winding grip 110 and the thimble 120 is inserted into the cylindrical tube body 130, so that the winding grip 110 and the thimble 120 are The tube body 130 deformed following the outer surface shape can be easily formed. Furthermore, according to the wire end fixing tool 100 of the present embodiment, since the overlapping portions of the winding grip 110 and the thimble 120 are overlapped, the overlapped portion can be easily covered with the tube body 130. Have Furthermore, in the present embodiment, since the thimble 120 is cantilevered by the winding grip 110 by the tube body 130, the arcuate portion 121 of the thimble 120 and the base end portion 111 of the winding grip 110 are curved during construction. There is an advantage that it is easy to cope with the shape difference.
