Description

  The present invention relates to a binding band. In particular, the present invention relates to a structure of a binding band that protects a bound body without damaging it when the binding band that binds the bound body such as a plurality of electric cables is cut.

  In substations or power plants, a binding band is used to bundle and wire a plurality of electric cables. FIG. 4 is a longitudinal sectional view showing a configuration of a binding band according to an example of the prior art. FIG. 5 is a plan view showing a configuration of a binding band according to an example of the prior art.

  FIG. 6 is a perspective view showing a use state of a binding band according to an example of the prior art. FIG. 7 is a cross-sectional view showing a state in which a plurality of electric cables are bundled with a binding band according to an example of the prior art.

  Referring to FIG. 4 or FIG. 5, the binding band 2 according to the prior art is integrally formed of synthetic resin or the like. The binding band 2 includes a quadrangular frustum-shaped head portion 2h, a band-shaped band portion 2b, and a tail portion 2t. The band portion 2b extends in a band shape from one end side of the head portion 2h. The tail portion 2t is formed on the end side of the band portion 2b.

  Referring to FIG. 4 or FIG. 5, the band portion 2b has a saw-tooth shaped locking groove 21b formed on one surface. On the other hand, the head portion 2h has a rectangular opening 21h and a locking claw 21n. The band portion 2b can be inserted into the opening 21h with the tail portion 2t at the head. The locking claw 21n protrudes into the opening 21h. And the latching claw 21n can mesh with the latching groove 21b of the band part 2b inserted in the opening 21h.

  Referring to FIG. 6 or FIG. 7, a plurality of electric cables C are bundled, and the periphery of these electric cables C is surrounded by a band portion 2b so that the locking groove 21b is inside. Next, the tail part 2t is inserted into the head part 2h with the tail part 2t at the head, and the tail part 2t is pulled with respect to the head part 2h so that the loop of the band part 2b is reduced in diameter. Cable C can be bundled. Next, as shown in FIG. 7, a series of bundling operations are completed by cutting off the extra length portion protruding from the head portion 2h with a cutting tool such as a nipper.

  With reference to FIGS. 4 to 7, when the band portion 2b is inserted into the head portion 2h, the locking groove 21b is engaged with the locking claw 21n to be detented. Generally, the binding band 2 is configured to be difficult to re-bind. Therefore, when there is a change in the wiring, the band portion 2b is cut with a cutting tool such as a nipper and the binding of the plurality of electric cables C is released.

  However, referring to FIG. 7, if the binding band 2 in which a plurality of electric cables C are bundled is cut with a cutting tool such as a nipper, there is a concern that the coating of the electric cables C may be damaged. There is a concern that damage to the electric cable C may cause a ground fault.

  In order to eliminate such problems, there is an insertion hole through which the band portion of the binding band can be inserted, and a separation space in which the cutting tool can be interposed between the outer surface of the electric cable and the binding band when the electric cable is bound. A binding band with a safety block is disclosed which includes a trapezoidal spacer formed with a pedestal that comes into contact with the outer surface of the electric cable and a pair of protruding pieces that are erected from the pedestal and have an insertion hole. (For example, refer to Patent Document 1).

  In the binding band according to Patent Document 1, when the band portion is cut from above the safety block, a base is interposed on the outer surface of the electric cable, so that the blade of the cutting tool can be prevented from coming into contact with the electric cable.

  Moreover, in order to eliminate the above problems, it is arranged between binding bands for binding a plurality of electric cables to protect the coating of the electric cables, and from a band plate that can be bent along the outer periphery of the electric cable bundle. In this band plate, there is disclosed a binding band with a cable guard spacer in which a pair of insertion holes through which the band portion of the binding band can be inserted are opened at both ends in the longitudinal direction (see, for example, Patent Document 2).

  The binding band according to Patent Document 2 can cut the band portion by sliding the cutting tool between the band portion of the binding band and the cable guard spacer, so the cutting tool does not directly contact the electric cable. It is said that there is no worry about damage.

  However, the binding band according to Patent Document 1 needs to assemble the safety block into the binding band every time the binding work is performed. Even if the work time for assembling the safety block into the binding band is short, if there are a large number of binding locations, there is a problem that the overall work efficiency is reduced if these assembly operations are accumulated. There is a need for a binding band that has a simple configuration that does not require assembly of separate parts, and that protects the bound body without damaging the bound band that bound the bound body.

  The binding band according to Patent Document 2 is the same. Even if the work time for assembling the cable guard spacers into the binding band is short, if there are a large number of binding points, there is a problem that the overall work efficiency is reduced if these assembly operations are accumulated.

  In particular, the binding band according to Patent Document 2 has a concern that it is difficult to slide the cutting tool between the band portion and the cable guard spacer when the electric cable bundle is strongly tightened at the band portion. There is a need for a binding band that has a simple configuration that does not require assembly of separate parts, and that protects the bound body without damaging the bound band that bound the bound body. The above can be said to be the subject of the present invention.

  The present invention has been made in view of such a problem, and has a simple configuration that does not require assembling separate parts, and damages the bound body when cutting the binding band that bound the bound body. An object of the present invention is to provide a binding band that can be protected without any problems.
