Definitions

  • the present invention relates to an electric cable, and is particularly effective when applied to a staying cable of an electric cable winding device.
  • the staying cable is pressed (biased) to the outer peripheral side of the reel by a linear spiral spring material.
  • An aspect of the present invention is to provide an electric cable effective when applied to a staying cable and other electric cables.
  • the electric cable of the present invention includes an elastically deformable spring material and an energizing core material.
  • the electric cable itself can have elasticity. Therefore, for example, if the present invention is applied to a staying cable or the like, a contactless cable reel can be reduced in size.
  • the spring material may also serve as a core material for energization.
  • the spring material and the core material may be covered and integrated with the covering material. If the electric cable is configured in this way, the entire device including the spring material can be handled as one cable, which is easy to use.
  • the spring material and the core material are desirably arranged adjacent to each other. And this invention is good to apply to the electric cable which has a plurality of core materials.
  • the spring material may be disposed between the core materials.
  • the electrical cable is configured in this manner, even if a plurality of core materials are twisted, the spring materials are arranged between the core materials, so that the spring materials are prevented from being twisted together with the core materials. it can.
  • the electric cable according to the present invention is applied to a staying cable of an electric cable winding device.
  • the “staying cable” means an electric cable used in a “contactless electric cable winding device” that does not have a sliding contact such as a slip ring.
  • the staying cable connects the winding electric cable wound around the winding drum and the power supply side, and is housed in the winding drum or the like to be used for the winding drum. Absorbs rotation.
  • the electric cable 1 is applied to an electric cable including a plurality (for example, four) of core members 3 for energization.
  • Each core member 3 is made of a material having excellent conductivity such as copper, and is covered with an electrically insulating coating material 3A.
  • an elastically deformable spring member 5 is disposed adjacent to the core member 3.
  • the spring material 5 is disposed substantially at the center of the electric cable 1.
  • the spring material 5 and the plurality of core materials 3 are covered and integrated by a flexible resin coating material 7 to form one electric cable.
  • the spring material 5 employs a metal such as spring steel, but may be other materials (for example, resin).
  • the spring material 5 and the plurality of core members 3 are integrated by being covered with a covering material, so that the whole including the spring material 5 can be handled as one electric cable. Is good.
  • the spring material 5 is arrange
  • the spring material 5 is disposed adjacent to the three core materials 3.
  • a spring member 5 having the same electrical conductivity as the core member 3 may be used. That is, the spring member 5 may also serve as the energizing core material.
  • the present embodiment is an example in which the electric cable according to the present invention is applied to a flat cable. Also in this embodiment, the spring material 5 is disposed adjacent to the three core materials 3.
  • the position where the spring material 5 is disposed is not limited to one end in the width direction.
  • the spring material 5 is disposed at the center in the width direction or both ends in the width direction. Also good.
  • the electric cable according to the present invention is applied to the staying cable of the winding device for the electric cable.
  • the present invention is not limited to this, and is inserted into a conduit such as a building. It can also be applied to electric cables.
  • the electrical cable in order to insert an electrical cable into a conduit such as a building, the electrical cable is usually connected to a string previously inserted in the conduit and the string is pulled out, or the flexibility and rigidity of a wire such as a wire This is done by inserting the provided wire so as to push it into the conduit, and then connecting the electrical cable to the rear end of the wire and pulling out the wire.
  • the electric cable since the electric cable itself has a function equivalent to that of the wire, the electric cable can be easily inserted into a conduit such as a building.
  • the cross-sectional shape of the spring material 5 is round.
  • the present invention is not limited to this, and may be other shapes such as a rectangular shape.
  • the spring material 5 is a leaf spring.
  • the spring material 5 since the spring material 5 was a metal, you may utilize the spring material 5 as a conduction
  • the covering material 7 and the spring material 5 are provided independently. However, the covering material 7 may function as the spring material 5.
  • covering material 7 was resin, this invention is not limited to this.
  • the core material 3 and the spring material 5 are integrated in the covering material 7, but the present invention is not limited to this, and for example, the spring material 5 is used as the covering material. It is good also as sticking to 3A, or arrange
  • the number of the spring members 5 is one.
  • the present invention is not limited to this.
  • a plurality of the spring members 5 and one core member 3 may be used.
  • the present invention is not limited to the above-described embodiment as long as it matches the gist of the invention described in the claims.
