Description

  The present invention relates to an electric wire binding that fixes two electric wires arranged close to each other in parallel at a connection point.

  Conventionally, a binding line is used to fix two electric wires arranged close to each other in parallel at a connection point where the distribution line branches in the middle of the span. The bind line is plastically deformable and is wound along two electric wires.

  Specifically, first, as shown in FIG. 6A, the central portion of the bind line 100 is bent into an inverted U shape so that both ends of the bind line 100 hang down. Next, the concave portion of the bent bind wire 100 is brought into contact with the outer peripheral surface of one of the two electric wires C, C. In this state, one operator grips one end portion of the bind wire 100 that hangs down with an indirect hot wire tool (insulating Yachko), and the other operator uses the bind hitter, and FIG. As shown in FIG. 1, the bind wire 100 is wound in a spiral shape sequentially from one end to the other end (see Patent Document 1).

Japanese Utility Model Publication No. 4-55713

  By the way, when the bind wire 100 is spirally wound around the two electric wires C and C, the bind wire 100 is bound with one operator holding one end portion of the hanging bind wire 100 and a bind hammer. The other worker who winds the wire 100 is required. In addition, since the bind wire 100 is sequentially wound in a spiral shape from one end to the other end, labor and time are required. Therefore, there is a problem that workability is not good for fixing two electric wires by the bind wire 100.

  In view of the above problems, an object of the present invention is to provide an electric wire binding that can be efficiently wound around two electric wires that are arranged close to each other in parallel to improve workability.

The electric wire binding according to the present invention is an electric wire to be fixed, which is two or more first hooking portions that can be hooked to one of the two electric wires arranged in parallel and close to each other. Two or more first hooks arranged at an interval in the axial direction corresponding to the extending direction of the two, and one formed continuously between two first hooks adjacent in the axial direction One or more second latching portions that can be latched to the other electric wire, and the first latching portion at the end that is latched to one electric wire, or A helical fixing portion formed continuously with the second hooking portion at the end that is hooked to the other electric wire, and formed so as to be wound around the one electric wire. with bets, of the two or more first hook portion, said first engaging portion of the first one to be hooked on one of the wires is smaller than the outer diameter of one wire It has a diameter, and a locking portion ends are formed by bending in the axial direction, and having an engagement portion for engaging the outer peripheral surface of one of the wire.

  According to this configuration, since the first hooking portion can be hooked on one of the electric wires, the first first hooking portion is hooked (supporting point) and starts to be wound around the two electric wires. Can do. Specifically, in a state where the first latching portion is hooked on one electric wire, after the second latching portion is hooked on the other electric wire, the second first latching portion is continuously attached to the one electric wire. After that, it becomes possible to wind a spiral fixing portion around one of the electric wires, and it is easy to wind all over. Moreover, it can support with respect to two electric wires by at least 3 points | pieces of a 1st latching part, a 2nd latching part, and a 1st latching part. Furthermore, by winding a helical fixing portion around one electric wire, it is possible to increase the fixing force for one electric wire while allowing the one electric wire to hang down.

In addition, according to such a configuration, the first first latching portion has an inner diameter smaller than the outer diameter of the electric wire. The electric wire is fitted into the first hooking portion while the inner diameter of the one hooking portion is expanded by the outer peripheral surface of the electric wire. For this reason, the inner surface of the first latching portion is in pressure contact with the outer peripheral surface of the electric wire, and the binding can be firmly fixed to the electric wire.

Further , the first first latching portion latched on one electric wire is an engaging portion formed by bending an end portion in the axial direction, and is engaged with the outer peripheral surface of the one electric wire. Since it has the latching | locking part to stop, the said 1st said 1st latching part latched by one electric wire is position-fixed with respect to one electric wire. Therefore, even if the binding is pulled toward the fixed side when winding, the position of the first first hooking portion that is hooked to one electric wire does not move, and the one electric wire Winding can be started efficiently with the first hooking portion to be hooked as a supporting point.

  As another aspect of the electric wire binding according to the present invention, it is preferable that the second latching portion includes a winding portion wound in a direction orthogonal to the axial direction.

  According to such a configuration, the second hooking portion includes the winding portion wound in the direction orthogonal to the axial direction of the electric wire, whereby the distance between the first hooking portions is reduced, and the two electric wires It is easy to wind with respect to the two wires, and the two wires can be easily restrained and firmly fixed.

  As described above, according to the present invention, it is possible to efficiently wind around two electric wires arranged close to each other in parallel and improve workability.

It is a figure which shows a state.

  An electric wire binding according to an embodiment of the present invention will be described with reference to the drawings. In addition, in this embodiment, the electric wire fixing tool applied to the structure which branches a distribution line in the middle of a span is demonstrated.

  First, before explaining this embodiment, the said branch structure is demonstrated. As shown in FIG. 1, the branch structure includes an electric wire C1 installed between utility poles, and an electric wire C2 branched from the electric wire C1 and held by a pin insulator B and a retaining clamp K. . The case where the two electric wires C1 and C2 arranged close to each other in parallel at the branch point have the same diameter will be described as an example.

  As shown in FIGS. 2 and 3, the electric wire binding according to the present embodiment includes two or more second wires that can be hooked to one electric wire C <b> 1 out of the two electric wires C <b> 1 and C <b> 2 that are arranged close to each other in parallel. One hooking portion 1a, which is adjacent to the two or more first hooking portions 1a arranged at an interval in the axial direction corresponding to the extending direction of the electric wire C1 to be fixed, in the axial direction. One or more second hooking portions 1b formed continuously between the two first hooking portions 1a and 1a, and one or more second hooking portions that can be hooked to the other electric wire C2. 1b and the first latching portion 1a at the most end latched by one electric wire C1 or the second latching portion 1b at the most end latched by the other electric wire C2 It is provided with a helical fixing portion 1c formed so as to be wound around one electric wire C1.

  In the present embodiment, for example, three first latching portions 1a are arranged at intervals in the axial direction corresponding to the extending direction of the electric wire C1 to be fixed.

  Of the two or more first hooks 1a, the first first hook 1a hooked to one electric wire C1 has an inner diameter smaller than the outer diameter of one electric wire C1, and It has the latching | locking part 10a which is the latching | locking part 10a formed by bending an end part in the said axial direction, Comprising: The latching | locking part 10a latched to the outer peripheral surface of one electric wire C1.

  In the present embodiment, for example, two second hooks 1b are formed continuously between the two first hooks 1a, 1a adjacent in the axial direction. Specifically, the second hooking portion 1b is wound in a direction orthogonal to the axial direction, with the first winding portion 10b wound in a direction obliquely intersecting the axial direction. And the second winding part 11b.

  In the present embodiment, for example, the fixing portion 1c is continuously formed in a spiral manner on the first hooking portion 1a at the end that is hooked on one of the electric wires C1.

  Next, a usage mode of the electric wire binding according to the present embodiment will be described. First, the inner surface of the 1st 1st latching part 1a latched by one electric wire C1 is contact | abutted to the outer peripheral surface of one electric wire C1 among the some 1st latching | locking parts 1a.

  At this time, since the first first hooking portion 1a hooked on one electric wire C1 has an inner diameter smaller than the outer diameter of the one electric wire C1, the inner diameter of the first hooking portion 1a. While being pushed and spread by the outer peripheral surface of one electric wire C1, one electric wire C1 is fitted into the first hooking portion 1a.

  And when the inner surface of the 1st 1st latching | locking part 1a press-contacts to the outer peripheral surface of the one electric wire C1 inserted, the 1st 1st latching | locking part to the outer peripheral surface of one electric wire C1 1a is hooked.

  Furthermore, the latching | locking part 10a of the 1st 1st latching | locking part 1a latched by one electric wire C1 latches on the outer peripheral surface of one electric wire C1. As a result, the one end part of the electric wire bind 1 can be firmly fixed with respect to one electric wire C1. Therefore, it is possible to start winding efficiently with the first hooking portion 1a as a support point. That is, it is easy to wind through the whole (including the second hooking portion 1b and the fixing portion 1c) using the first first hooking portion 1a as a supporting point.

  Next, the first second latching portion 1b is continuously hooked while the first first latching portion 1a latched on one electric wire C1 is fixed. Specifically, from the end opposite to the locking portion 10a of the first first locking portion 1a hooked to the one electric wire C1, in a direction obliquely intersecting the axial direction. After the first first winding portion 10b is continuously wound, the first second hooking portion 1b is hooked to the other electric wire C2.

  Next, the first second winding portion 11b is continuously wound from the end of the first second latching portion 1b in the direction orthogonal to the axial direction, and then the second 1st latching | locking part 1a is latched by one electric wire C1. Therefore, the two electric wires C1 and C2 are supported at at least three points of the first hooking portion 1a, the second hooking portion 1b, and the first hooking portion 1a.

  Since the second winding portion 11b of the second latching portion 1b is wound in a direction orthogonal to the axial direction of one electric wire C1, the distance between the adjacent first latching portions 1a and 1a is short. Thus, the two electric wires C1 and C2 can be easily wound and the two electric wires C1 and C2 can be easily restrained and firmly fixed.

  Next, after the first winding portion 10b is continuously wound from the end portion of the second first latching portion 1a in a direction obliquely intersecting with the axial direction, The second hooking portion 1b is hooked to the other electric wire C2.

  Next, after the second second winding portion 11b is continuously wound in the direction orthogonal to the axial direction from the end of the second second hooking portion 1b, A certain first latching portion 1a is latched to one electric wire C1.

  Then, the helical fixing | fixed part 1c is wound around one electric wire C1 from the edge part of the 1st latching | locking part 1a which is the end.

  Since this fixed portion 1c is formed continuously in a spiral manner on the first hook portion 1a at the end that is hooked to one electric wire C1, while allowing the electric wire C1 to hang down, The fixing force with respect to one electric wire can be raised. As a result, one electric wire C1 can be supported linearly.

  And as shown in FIG.2 and FIG.3, the 1st latching part 1a, the 1st winding part 10b, the 2nd latching part 1b, and the 2nd winding part 11b are helical in two electric wires C1 and C2. And the two electric wires C1 and C2 are restrained.

  Thus, according to the electric wire binding which concerns on this embodiment, it can wind efficiently with respect to the two electric wires arrange | positioned adjacently and parallel, and workability | operativity can be improved.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.

  For example, in the case of the above-described embodiment, the case of branching in the middle of the span has been described as an example, but the present invention can also be applied to a branch point in the middle of the span by the polymer spacer and a branch point branched in the middle of the span of the line spacer.

  In the case of the above-described embodiment, the case where the electric wire having the same diameter is fixed has been described as an example. However, as shown in FIGS. 4 and 5, for example, in the drawing structure of the low-voltage line from the high-voltage line, two wires having different diameters are used. It can also be applied to the case of fixing the electric wire.

  Moreover, in the said embodiment, although the 1st latching | locking part 1a was made into three and the 2nd latching | hanging part 1b was made into two, the frequency | count of winding is not limited and the 1st latching | locking part 1a is two or more Thus, the number of the second latching portions 1b may be one or more.

  Moreover, in the case of the said embodiment, although the fixing | fixed part 1c was formed in the 1st latching | locking part 1a in the end most latched by one electric wire C1, it is the 1st in the end most latched by the other electric wire C2. You may form the fixing | fixed part 1c in the two latching | locking part 1b.
