In the inclusion 5 of this embodiment, at least the surface of each partition wall 51 facing each accommodation space 52 is formed of the same kind of material as the insulating coating 42 of the wire core 4. Here, the surface of each partition wall 51 facing each accommodation space 52 is formed of PVC, which is the same kind of material as the insulating coating 42.

  More specifically, the inclusion 5 of the present embodiment is configured to include a main body portion 53 constituting a plurality of partition walls 51 and a tensile body 54 built in the main body portion 53. The main body 53 is a radial portion (cross-shaped portion) that includes a plurality of partition walls 51, and extends along the extending direction (axial direction).

Here, the main body 53 is made of PVC, which is the same kind of material as the insulating coating 42, and the tensile body 54 is made of an aramid resin fiber such as Kevlar (registered trademark), for example. The inclusion 5 is formed by integrally molding the main body 53 and the tensile body 54 by two-color molding or the like.

  The stranded wire core 2 is composed of a plurality of wire cores 4 and inclusions 5 configured as described above. That is, the stranded wire core 2 is configured by twisting the plurality of wire cores 4 and the inclusions 5 accommodated in the plurality of accommodating space portions 52. The stranded wire core 2 includes a plurality of wire cores 4 along the surroundings of the inclusions 5, that is, a plurality of wire cores 4 along the partition walls 51 in the housing spaces 52. The wire core 4 and the inclusion 5 are twisted together. The present stranded wire core 2 of the present embodiment is a four-core obtained by twisting a total of four power wires 4A, 4B, one ground wire 4C, and one communication wire 4D as a plurality of wire cores 4.

In addition, the stranded wire core 2 has a surplus length of about 0.5 to 4%, for example, compared to the case where each wire core 4 does not slide so that each wire core 4 can slide in the accommodating space 52. It is preferable to have. In this case, each wire core 4 is preferably set so that the wire core length L1 satisfies, for example, the following formula (1). In Equation (1), “L1” represents the wire core length, “P” represents the twisting rate, “L” represents the total length of the cabtire cable 1, and “α” represents the coefficient. The twisting rate P is also referred to as a twisting factor, and corresponds to the percentage of how much the actual length per pitch of the twisted wire core 4 is longer than the length of one pitch. . The coefficient α is a coefficient set according to a desired extra length in each wire core 4 and is set to about 1.005 to 1.04 here.

L1 = P × L × α (1)

Here, the stranded wire core 2 can suppress the effect of sliding the wire cores 4 in the accommodating space 52 from becoming relatively small by setting the coefficient α to α ≧ 1.005. , Α ≦ 1.04 can suitably suppress the occurrence of buckling.

  The protective material 3 covers the outer periphery of the stranded wire core 2, and here includes a press-wound tape 6 and a sheath 7 as an outermost insulating coating.

  The holding tape 6 is wound around the main strand 2. The press-wrapping tape 6 is made of, for example, polyester, and a total of four power wires 4A, 4B, one ground wire 4C, and one communication wire 4D constituting the stranded wire core 2. They are wound around in a twisted state to bundle them. The press-winding tape 6 of this embodiment is wound around the front end portion 51 b of the plurality of partition walls 51 on the outer side of the main strand 2. Thereby, the press-wrapping tape 6 partitions the accommodation space 52 together with the plurality of partition walls 51. That is, the press-wound tape 6 defines the outer side in the radial direction of each housing space 52. In the stranded wire core 2, a gap is formed between each partition wall 51, each wire core 4, and the presser winding tape 6 of the inclusion 5 in a state where the presser winding tape 6 is wound.

  The sheath 7 covers the outer peripheral side of the press-winding tape 6 wound around the stranded wire core 2. Here, the sheath 7 is provided in contact with the outer peripheral surface of the press-wound tape 6. The sheath 7 is formed, for example, by extruding an insulating resin material (PP, PVC, cross-linked PE, etc., which is appropriately selected in consideration of wear resistance, chemical resistance, heat resistance, etc.). The Here, the sheath 7 is formed of PVC, for example. The sheath 7 has a substantially annular cross-sectional shape (a cross-sectional shape in a direction orthogonal to the extending direction). Thereby, the cabtire cable 1 has a substantially circular cross-sectional shape as a whole. Here, the cabtire cable 1 is formed to have an outer diameter of about 12 mm, for example.

  According to the cabtire cable 1 described above, a plurality of housings defined by a plurality of wire cores 4 in which a linear conductor 41 is covered with an insulating coating 42 made of an insulating resin material, and a plurality of partition walls 51. A book that includes an inclusion 5 in which at least one wire core 4 is accommodated in each of the space portions 52, and is formed by twisting the plurality of wire cores 4 and the inclusions 5 accommodated in the plurality of accommodation space portions 52. A stranded wire core 2 and a protective material 3 covering the outer periphery of the stranded wire core 2 are provided. According to the connector-equipped cable 200 described above, the cabtire cable 1 having the main stranded wire core 2 and the protective material 3 and the inlet 102 provided at the end of the cabtire cable 1 and provided in the vehicle. And a charging connector 210 to be fitted to the housing. The surface of the partition wall 51 facing the accommodation space 52 and the insulating coating 42 are formed of the same kind of material, here, PVC.

  Therefore, in the cabtire cable 1 and the cable with connector 200, at least one wire core 4 is accommodated in the plurality of accommodating space portions 52 in the main strand 2 in which the plurality of wire cores 4 and the inclusions 5 are twisted together. Therefore, the partition wall 51 which partitions the accommodation space part 52 can be interposed between the plurality of wire cores 4, and the wire cores 4 can be arranged apart from each other. And the cabtire cable 1 and the cable 200 with a connector can suppress the occurrence of twist breakage or the like in the stranded wire core 2 by interposing the partition walls 51 between the plurality of wire cores 4. In particular, the cabtire cable 1 and the cable with connector 200 can be arranged such that a plurality of wire cores 4 having different outer diameters, which tend to be twisted, are separated from each other by a partition wall 51. It can suppress more reliably. As a result, even if the cabtire cable 1 and the connector-attached cable 200 are repeatedly deformed because the entire cabtire cable 1 is bent or twisted, the twisted wire core 2 is not twisted. Since generation | occurrence | production can be suppressed, it can suppress that a wave | undulation etc. generate | occur | produce. Further, even when the cabtire cable 1 and the connector-attached cable 200 are repeatedly deformed because the entire cabtire cable 1 is bent or twisted, for example, each wire core 4 follows the deformation. Therefore, the stress can be relieved and the occurrence of buckling can be suppressed. Thereby, the cabtire cable 1 and the cable with connector 200 can suppress buckling and disconnection even when the entire cabtire cable 1 is bent or twisted and repeatedly deformed. . Further, since the cabtire cable 1 and the cable with connector 200 are formed of the same kind of material on the surface of the partition wall 51 facing the accommodation space 52 and the insulating coating 42 of the wire core 4, for example, Even if the partition wall 51 comes into contact, it is possible to suppress the plastic material contained in the insulating coating 42 from moving to the partition wall 51 side. Thereby, the cabtyre cable 1 and the cable 200 with a connector can suppress deterioration, such as a crack of the insulation coating 42 of the wire core 4, and can improve durability. As a result, the cabtyre cable 1 and the connector-attached cable 200 can improve the disconnection resistance. The cabtire cable 1 and the connector-attached cable 200 can improve the resistance to disconnection in a usage mode in which deformation such as bending or twisting of the entire cabtire cable 1 is prominently performed.

  Furthermore, according to the cabtyre cable 1 described above, in the main twisted wire core 2, the plurality of wire cores 4 and the inclusions 5 are twisted together so that the wire core 4 can slide in the accommodating space 52. Therefore, when the cabtyre cable 1 and the cable with connector 200 are repeatedly deformed because the entire cabtyre cable 1 is bent or twisted, each wire core 4 moves more freely in the accommodation space 52. Therefore, the stress can be relaxed more reliably and the occurrence of buckling can be more reliably suppressed.

  Furthermore, according to the cabtire cable 1 described above, the inclusion 5 has an allowable tension with respect to the extending direction of the main strand 53 and the main strand 53 constituting the plurality of partition walls 51 and the main strand 53. It has a strength member 54 that is relatively larger than the main body 53. Therefore, the cabtire cable 1 and the cable with connector 200 can be prevented from being disconnected even if an excessive tension is applied to the cabtire cable 1 by the strength member 54, and the main body 53 including the partition wall 51 can be formed thereon. The insulating coating 42 can be formed of the same material. As a result, the cabtire cable 1 and the connector-attached cable 200 can achieve both the suppression of deterioration of the insulating coating 42 due to the migration of the plastic material contained in the insulating coating 42 and the suppression of disconnection due to excessive tension.

  Furthermore, according to the cabtire cable 1 described above, the plurality of partition walls 51 are formed in a tapered shape toward the outside of the stranded wire core 2. Therefore, the cabtire cable 1 and the connector-attached cable 200 can prevent the wire core 4 from being caught by the partition wall 51 when the cabtire cable 1 is repeatedly deformed by being bent or twisted. It is possible to suppress the movement of each wire core 4 within the accommodation space 52 from being inhibited.

  Furthermore, according to the cabtire cable 1 described above, the protective material 3 is wound around the front end portion 51 b of the plurality of partition walls 51 on the outer side of the main strand wire 2, so that the accommodating space portion 52 together with the plurality of partition walls 51 is provided. It is comprised including the press-wound tape 6 that divides the head. Accordingly, the cabtire cable 1 and the cable with connector 200 can reliably secure the accommodating space 52 in which each wire core 4 can be moved by the plurality of partition walls 51 and the press-wrapping tape 6. It is possible to reliably ensure a movable state in the space 52.

The stranded wire core 302 includes a plurality of wire cores 304 along the periphery of the inclusions 305, that is, a plurality of wire cores 304 along the partition walls 351 in the housing spaces 352. The wire core 304 and the inclusions 305 are twisted together. The stranded wire core 302 of the present embodiment constitutes a three-core stranded wire obtained by twisting a total of three power wires 4A, 4B, and one stranded wire core 304E as the plurality of wire cores 304. In the stranded wire core 302, a plurality of wire cores 304 and inclusions 305 are twisted together so that each wire core 304 can slide in the accommodating space 352. The presser winding tape 6 is wound around the front end portion 351 b of the plurality of partition walls 351 outside the main strand wire core 302. The cabtire cable 301 of the present embodiment is formed with an outer diameter of about 15 mm, for example.

  In the cabtire cable 301 and the cable 400 with a connector described above, in the main stranded wire core 302 obtained by twisting a plurality of wire cores 304 and inclusions 305, at least one wire core 304 is provided in the plurality of accommodating space portions 352. Since it is accommodated, the partition 351 which divides the accommodation space part 352 can be interposed between the some wire core 304, and each wire core 304 can be arrange | positioned mutually spaced apart. Further, even when the cabtyre cable 301 and the cable with connector 400 are repeatedly deformed because the entire cabtyre cable 301 is bent or twisted, for example, each wire core 304 follows the deformation. Therefore, the stress can be relieved and the occurrence of buckling can be suppressed. Furthermore, since the cabtyre cable 301 and the cable 400 with a connector are formed of the same kind of material on the surface of the partition wall 351 facing the housing space 352 and the insulating coating 42 of the wire core 304, for example, Even when the partition wall 351 comes into contact, the plastic material contained in the insulating coating 42 can be prevented from moving to the partition wall 351 side. As a result, the cabtyre cable 301 and the connector-attached cable 400 can improve the resistance to disconnection.

  The cabtyre cable and the connector-attached cable according to the above-described embodiment of the present invention are not limited to the above-described embodiment, and various modifications can be made within the scope described in the claims. The cabtire cable and the connector-attached cable according to the present embodiment may be configured by appropriately combining the components of the embodiments described above.

  In the above description, the cabtyre cable is described as being a quick charge cable, but is not limited thereto.

  In the above description, the surfaces of the partition walls 51 and 351 facing the accommodation space portions 52 and 352 and the insulating coating 42 are described as being formed of PVC. However, the present invention is not limited thereto, and is formed of the same kind of material. It only has to be done. In addition, the inclusions 5 and 305 may include, for example, a conductive material such as carbon black in the same kind of material as the insulating coating 42. In this case, the cabtyre cable and the cable with the connector can reduce electromagnetic noise propagating between the wire cores 4 and 304, and can improve, for example, noise resistance performance of the communication line 4D.

  The plurality of wire cores described above are a conductor in which a plurality of strands are twisted together, and an insulating wire core formed by including an insulating coating that is formed of an insulating resin material and covers the outer peripheral side of the conductor, or What is necessary is just to comprise including the strand wire core which twisted the some insulated wire core, for example, may be comprised by the strand wire core like all the strand wire cores 304E.

  In the inclusion 5 described above, the four accommodating spaces 52 are defined by the four partition walls 51, and the inclusion 305 is described as the three accommodating spaces 352 defined by the three partition walls 351. The number of the partition walls 51 and 351 and the accommodating space portions 52 and 352 is not limited to this, and may be five, six, or more, and may be appropriately determined according to the number of applied wire cores 4 and 304. It only has to be set.
