[0010] The present invention will be described below in accordance with preferred embodiments. Note that the present invention is not limited to the embodiments described below, and the embodiments described below can be modified as appropriate without departing from the spirit of the present invention. In addition, in the embodiments described below, some components are omitted from illustration and description, but for the details of the omitted technologies, publicly known or well-known technologies are applied as appropriate within the scope of not causing any contradictions with the content described below.

[0011] FIG. 1 is a front view showing an electric wire with connector 1 according to one embodiment of the present invention. The electric wire with connector 1 shown in this figure includes a connector 2, a plurality of electric wires 3, and a tape 4. The connector 2 includes a housing 21 in which a plurality of cavities (not shown) are formed to accommodate terminals (not shown) crimped to the ends of the electric wires 3. This housing 21 is mated with a housing (not shown) of a mating connector (not shown). When this housing and the housing 21 are mated, the terminals of the electric wires 3 and the terminals (not shown) provided on the mating connector are electrically connected.

[0012] The housing 21 has a cylindrical neck portion 211. The neck portion 211 has a circular surface where an insertion opening for the electric wire 3 is provided, and a circular outer peripheral surface. Note that the neck portion 211 does not necessarily have to be cylindrical, and the shape of the neck portion 211 may be any shape (for example, a rectangular parallelepiped shape) around which the tape 4 can be wound.

[0013] The electric wire 3 includes a conductive core wire (not shown) and an insulating coating 31 that covers the core wire. At the end of the electric wire 3, the core wire is exposed from the coating 31, and the terminal is crimped to the exposed part of the core wire. While Fig. 1 shows an example in which two electric wires 3 are wired side by side (top and bottom in the figure), three or more electric wires 3 may be wired side by side or top and bottom (front and back in the figure).

[0014] The tape 4 is a nonwoven fabric tape, a PVC (polyvinyl chloride) tape, or the like, and is wound around the neck portion 211 of the housing 21 and the plurality of electric wires 3 to form a covering portion 10 that covers the neck portion 211 and the vicinity of the ends of the plurality of electric wires 3. The covering portion 10 is formed from a single piece of tape 4 and includes an underneck winding portion 11, a first cross winding portion 12, an electric wire winding portion 13, a second cross winding portion 14, and a lap winding portion 15.

[0015] The underneck winding portion 11 is formed by winding the tape 4 around the underneck portion 211 two times. The first cross winding portion 12 is formed by stretching the tape 4 at the end of the underneck winding portion 11 from the underneck winding portion 11 around the plurality of electric wires 3 at an angle so as to cross the electric wires 3 diagonally. The electric wire winding portion 13 is formed by winding the tape 4 at the end of the first cross winding portion 12 around the plurality of electric wires 3 two times. The second cross winding portion 14 is formed by stretching the tape 4 at the end of the electric wire winding portion 13 from the electric wire winding portion 13 to the underneck winding portion 11 at an angle so as to cross the electric wires 3 diagonally. The lap winding portion 15 is formed by spirally lap winding the tape 4 at the end of the second cross winding portion 14 around the underneck winding portion 11, the first cross winding portion 12, the second cross winding portion 14, and the electric wire winding portion 13.

[0016] The first cross winding portion 12 is stretched obliquely from the upper side of the neck portion 211 to the lower left in the figure, while the second cross winding portion 14 is stretched obliquely from the upper side of the wire winding portion 13 to the lower right in the figure. In other words, when viewed in the front-to-rear direction in the figure, the first cross winding portion 12 and the second cross winding portion 14 intersect.

[0017] The lap width of the lap winding portion 15 (the overlapping width of adjacent tapes 4) is half the width of the tape 4, and the lap winding portion 15 is formed by half-lap winding of the tape 4. It is not essential that the lap width of the lap winding portion 15 be half the width of the tape 4, but from the viewpoint of reducing the amount of tape 4 used, the lap width of the lap winding portion 15 is preferably less than two-thirds the width of the tape 4, and more preferably equal to or less than half the width of the tape 4.

[0018] 2 to 5 are front views showing the manufacturing process of the connector-attached electric wire 1 shown in Fig. 1. As shown in Fig. 2 and Fig. 3, first, the underneck wrapping portion 11 is formed by wrapping the tape 4 around the neck portion 211 twice. The width of the tape 4 is narrower than the width of the outer peripheral surface of the neck portion 211.

[0019] As shown in Fig. 2, the tape 4 is wound around the underneck portion 211 once, and then, as shown in Fig. 3, the tape 4 is wound around the underneck portion 211 while tilting it towards the electric wire 3 (to the left in the figure). Next, as shown in Fig. 4, the tape 4 at the end of the underneck winding portion 11 is stretched obliquely from the underneck winding portion 11 onto the plurality of electric wires 3 to form the first cross winding portion 12. Next, the tape 4 at the end of the first cross winding portion 12 is wound around the plurality of electric wires 3 two times to form the electric wire winding portion 13.

[0020] Next, as shown in Fig. 5, the tape 4 at the end of the wire winding portion 13 is stretched obliquely from the wire winding portion 13 to the under-neck winding portion 11 to form the second cross winding portion 14. At this time, the second cross winding portion 14 is stretched obliquely so that the first cross winding portion 12 and the second cross winding portion 14 cross each other.

[0021] Next, as shown in Fig. 6, the tape 4 at the end of the second cross winding portion 14 is spirally wrapped around the under-neck wrapping portion 11, the first cross winding portion 12, the second cross winding portion 14, and the electric wire winding portion 13 to form a wrapped portion 15. In this embodiment, the wrapped portion 15 is formed by half-wrapping the tape 4.

[0022] 7 is a front view showing the manufacturing process of a connector-attached electric wire 300 according to a comparative example. As shown in this figure, in the manufacturing process of the connector-attached electric wire 300 according to the comparative example, the underneck wrapping portion 11 is formed by winding the tape 4 twice around the neck portion 211, and then the lap winding portion 15C is formed by winding the tape 4 at the end of the underneck wrapping portion 11 around the underneck wrapping portion 11 and multiple electric wires 3. Then the tape 4 at the end of the lap winding portion 15C is wound twice around multiple electric wires 3 to form the electric wire winding portion 13.

[0023] In the manufacturing process of the electric wire with connector 300 according to the comparative example, the wrap width of the wrap winding portion 15C is set to 2 / 3 of the width h of the tape 4 in order to prevent misalignment of the tape 4. The amount of tape 4 used in the electric wire with connector 300 according to the comparative example and the electric wire with connector 1 according to the above embodiment will be examined below.

[0024] If the width h of the tape 4 is 19 mm, the length l of the section around which the tape 4 is wound is 60 mm, and the diameter d of the cylindrical neck portion 211 is 30 mm, in the manufacturing process of the electric wire with connector 300 according to the comparative example, the amount of tape 4 used is 1268 mm, as shown in the following formula (1).

[0025] Amount of tape 4 used = under-neck winding section 11 + wrap winding section 15C + wire winding section 13 =(d×π×2)+{(d×π×l) / (h / 3)}+(d×π×2) =(30×π×2)+{(30×π×60) / (19 / 3)}+(30×π×2) ≒1268mm (1)

[0026] In contrast, if the width h of the tape 4, the length l of the above section, and the diameter d of the cylindrical neck portion 211 are kept the same, the amount of tape 4 used in the manufacturing process of the connector-equipped electric wire 1 according to the above embodiment will be 1105 mm, as shown in the following formula (2).

[0027] Amount of tape 4 used = under-neck winding section 11 + first cross winding section 12 + electric wire winding section 13 + second cross winding section 14 + lap winding section 15 =(d×π×2)+√(l 2 +d 2 )+(d×π×2)+√(l 2 +d 2 )+{(d×π×l) / (h / 2)} =(30×π×2)+√(60 2 +30 2 )+(30×π×2)+√(60 2 +30 2 )+{(30×π×60) / (19 / 2)} ≒1105mm (2)

[0028] As described above, in the electric wire with connector 1 according to this embodiment, in the covering portion 10, the under-neck winding portion 11 is formed by wrapping the tape 4 around the under-neck portion 211, the wire winding portion 13 is formed by wrapping the tape 4 around the electric wire 3, the first cross winding portion 12 and the second cross winding portion 14 are formed by stretching the tape 4 between the under-neck winding portion 11 and the wire winding portion 13 so as to cross the electric wire 3, and the wrap winding portion 15 is formed by wrapping the tape 4 over the first cross winding portion 12 and the second cross winding portion 14.

[0029] According to the connector-attached electric wire 1 of this embodiment, the tape 4 forming the first cross winding portion 12 and the second cross winding portion 14 crosses the electric wire 3 between the neck portion 211 and the electric wire 3 in a tensioned state. This makes it possible to form the wrap winding portion 15 by wrapping the tape 4 in a state where the step between the neck portion 211 and the electric wire 3 is eliminated. This makes it possible to prevent the tape 4 from shifting in the wrap winding portion 15. Furthermore, since it is possible to prevent the tape 4 from shifting in the wrap winding portion 15, it is not necessary to make the width of the tape 4 wider than necessary, and therefore it is possible to suppress an increase in the number of steps required for winding the tape 4 and the amount of tape 4 used.

[0030] Furthermore, in the connector-attached electric wire 1 according to this embodiment, the first cross winding portion 12 and the second cross winding portion 14 are stretched so as to cross each other between the neck portion 211 and the electric wire 3. This enhances the effect of eliminating the step between the neck portion 211 and the electric wire 3, and enhances the effect of preventing the tape 4 in the wrap winding portion 15 from shifting.

[0031] Furthermore, in the connector-attached electric wire 1 according to this embodiment, the covering 10 is formed by wrapping one tape 4 around the neck portion 211 and the electric wire 3. This means that one tape 4 is sufficient to wrap around the neck portion 211 and the electric wire 3, and the processes from two turns around the neck portion 211 to lap winding can be carried out continuously. Therefore, there is no need to separately prepare tapes for cross winding and lap winding, or to separately carry out the cross winding process and the lap winding process, which simplifies management of materials and processes.

[0032] Furthermore, in the manufacturing method of the electric wire with connector 1 according to this embodiment, the following steps are carried out: a step of forming the under-neck winding portion 11 by winding the tape 4 around the under-neck portion 211; a step of forming the electric wire winding portion 13 by winding the tape 4 around the electric wire 3; a step of forming the first cross winding portion 12 and the second cross winding portion 14 by stretching the tape 4 between the under-neck winding portion 11 and the electric wire 3 so that it crosses the electric wire 3; and a step of forming the lap winding portion 15 by lap winding the tape 4 over the first cross winding portion 12 and the second cross winding portion 14.

[0033] According to the manufacturing method of the connector-attached electric wire 1 according to the present embodiment, the tape 4 forming the first cross winding portion 12 and the second cross winding portion 14 is pulled and crossed with the electric wire 3 between the neck portion 211 and the electric wire 3. This makes it possible to form the wrap winding portion 15 by wrapping the tape 4 in a state where the step between the neck portion 211 and the electric wire 3 is eliminated. This makes it possible to prevent the tape 4 from shifting in the wrap winding portion 15. Furthermore, since it is possible to prevent the tape 4 from shifting in the wrap winding portion 15, it is not necessary to make the width of the tape 4 wider than necessary, and therefore it is possible to suppress an increase in the number of steps required for winding the tape 4 and the amount of tape 4 used.

[0034] Furthermore, in the manufacturing method of the connector-attached electric wire 1 according to this embodiment, the step of forming the underneck winding portion 11 is performed followed by the step of forming the first cross winding portion 12, and the step of forming the first cross winding portion 12 is performed followed by the step of forming the electric wire winding portion 13. This allows the first cross winding portion 12 to be maintained in a tensioned state between the underneck winding portion 11 and the electric wire winding portion 13.

[0035] Furthermore, in the manufacturing method of the connector-attached electric wire 1 according to this embodiment, the step of forming the underneck winding portion 11, the step of forming the first cross winding portion 12, and the first step of forming the electric wire winding portion 13 are carried out in that order, and then the second step of forming the second cross winding portion 14 is carried out. At this time, the tape 4 is stretched between the underneck portion 211 and the electric wire 3 so that they cross each other. This enhances the effect of eliminating the step between the underneck portion 211 and the electric wire 3, and enhances the effect of preventing the tape 4 from shifting in the wrap winding portion 15.

[0036] Furthermore, in the manufacturing method of the connector-attached electric wire 1 according to this embodiment, the covering 10 is formed by wrapping one tape 4 around the neck portion 211 and the electric wire 3. That is, the processes from wrapping two turns around the neck portion 211 to lap winding are performed continuously using one tape 4. Therefore, there is no need to separately prepare tapes for cross winding and lap winding, or to separately perform the cross winding process and the lap winding process, which simplifies management of materials and processes.

[0037] 8 is a front view showing a modified example of the manufacturing process of the connector-attached electric wire 1 shown in FIG. 1. As shown in this figure, the electric wire winding portion 13 is formed by winding the tape 4 twice around a plurality of electric wires 3, and then the tape 4 at the end of the electric wire winding portion 13 is stretched from the electric wire winding portion 13 to the underneck portion 211 diagonally so as to intersect with the electric wires 3, thereby forming the second cross winding portion 14. Then the tape 4 at the end of the second cross winding portion 14 is wound twice around the underneck portion 211 to form the underneck winding portion 11, and then the tape 4 at the end of the underneck winding portion 11 is stretched diagonally around the electric wire winding portion 13 to form the first cross winding portion 12 (not shown). Then the tape 4 at the end of the first cross winding portion 12 is lap-wound around the electric wire winding portion 13, the second cross winding portion 14, the first cross winding portion 12, and the underneck winding portion 11 to form the lap winding portion 15 (not shown).

[0038] As described above, in the manufacturing method of the electric wire with connector 1 according to the modified example, after the step of forming the electric wire winding portion 13, the step of forming the second cross winding portion 14 is performed, and then the step of forming the underneck winding portion 11 is performed. This makes it possible to maintain the second cross winding portion 14 in a tensioned state between the electric wire winding portion 13 and the underneck winding portion 11.

[0039] 9 is a front view showing a manufacturing process of an electric wire with connector 100 according to another embodiment of the present invention. The electric wire with connector 100 shown in this figure includes an outer jacket 101 through which a plurality of electric wires 3 are inserted. In this embodiment, the outer jacket 101 is a corrugated tube.

[0040] 9, the underneck wrapping portion 11 is formed by wrapping the tape 4 around the underneck portion 211 two times, and then the tape 4 at the end of the underneck wrapping portion 11 is stretched from the underneck wrapping portion 11 to the exterior sheathing 101 so as to diagonally intersect with the wire 3, thereby forming a first cross winding portion 12. The tape 4 at the end of the first cross winding portion 12 is then wrapped around the exterior sheathing 101 two times to form an exterior sheathing wrapping portion 13A. The tape 4 at the end of the exterior sheathing wrapping portion 13A is then stretched from the exterior sheathing wrapping portion 13A to the underneck wrapping portion 11 so as to diagonally intersect with the wire 3, thereby forming a second cross winding portion 14, and then the tape 4 at the end of the second cross winding portion 14 is lap wound around the underneck wrapping portion 11, the first cross winding portion 12, the second cross winding portion 14, and the exterior sheathing wrapping portion 13A to form a lap winding portion 15 (not shown).

[0041] As described above, in the electric wire with connector 100 according to this embodiment, in the covering portion 10, the under-neck winding portion 11 is formed by wrapping the tape 4 around the under-neck portion 211, the outer casing material winding portion 13A is formed by wrapping the tape 4 around the outer casing material 101, the first cross winding portion 12 and the second cross winding portion 14 are formed by stretching the tape 4 between the under-neck winding portion 11 and the outer casing material winding portion 13A so as to cross the electric wire 3, and the lap winding portion 15 is formed by wrapping the tape 4 over the first cross winding portion 12 and the second cross winding portion 14.

[0042] According to the electric wire with connector 100 of this embodiment, the tape 4 forming the first cross winding portion 12 and the second cross winding portion 14 crosses the electric wire 3 between the neck portion 211 and the outer casing 101 in a tensioned state. This makes it possible to form the lap winding portion 15 by wrapping the tape 4 in a state where the step between the neck portion 211 and the outer casing 101 is eliminated. This prevents the tape 4 from shifting in the lap winding portion 15. Furthermore, since the tape 4 can be prevented from shifting in the lap winding portion 15, it is not necessary to make the width of the tape 4 wider than necessary, which prevents an increase in the number of steps required for winding the tape 4 and the amount of tape 4 used.

[0043] 10 and 11 are front views showing a manufacturing process of an electric wire with connector 200 according to another embodiment of the present invention. In the electric wire with connector 200 shown in these figures, the first cross winding portion 12 and the second cross winding portion 14 are formed on the lap winding portion 15.

[0044] As shown in Fig. 10, first, the lap winding portion 15 is formed by wrapping the tape 4 around the neck portion 211 and the plurality of electric wires 3. Then, as shown in Fig. 11, the tape 4 at the end of the lap winding portion 15 is stretched from the tip of the lap winding portion 15 to the neck portion 211 so as to diagonally intersect with the electric wires 3, thereby forming the first cross winding portion 12. Then, the tape 4 at the end of the first cross winding portion 12 is wound around the neck portion 211 two times to form the underneck winding portion 11, and then the tape 4 at the end of the underneck winding portion 11 is stretched from the neck portion 211 to the tip side of the lap winding portion 15 so as to diagonally intersect with the electric wires 3, thereby forming the second cross winding portion 14 (not shown). Then, the tape 4 at the end of the second cross winding portion 14 is wound around the tip of the lap winding portion 15 two times to form the electric wire winding portion 13 (not shown).

[0045] As described above, in the electric wire with connector 200 according to this embodiment, in the covering portion 10, the under-neck winding portion 11 is formed by wrapping the tape 4 around the under-neck portion 211, the electric wire winding portion 13 is formed by wrapping the tape 4 around the electric wire 3, the first cross winding portion 12 and the second cross winding portion 14 are formed by stretching the tape 4 between the under-neck winding portion 11 and the electric wire winding portion 13 so as to cross the electric wire 3, and the wrap winding portion 15 is formed by wrapping the tape 4 under the first cross winding portion 12 and the second cross winding portion 14.

[0046] According to the connector-attached electric wire 200 of this embodiment, the tape 4 forming the first cross winding portion 12 and the second cross winding portion 14 crosses the electric wire 3 between the neck portion 211 and the electric wire 3 in a pulled state. This makes it possible to eliminate a step between the neck portion 211 and the electric wire 3 after the wrap winding portion 15 is formed. This makes it possible to prevent the tape 4 from shifting in the wrap winding portion 15. Furthermore, since it is possible to prevent the tape 4 from shifting in the wrap winding portion 15, it is not necessary to make the width of the tape 4 wider than necessary, and therefore it is possible to suppress an increase in the number of steps required for winding the tape 4 and the amount of tape 4 used.

[0047] The present invention has been described above based on the above embodiment, but the present invention is not limited to the above embodiment, and modifications may be made to the above embodiment within the scope of the spirit of the present invention, or publicly known or well-known technologies may be combined as appropriate.

[0048] For example, in the above embodiment, the first cross winding portion 12 and the second cross winding portion 14 are formed, but it is also possible to form only one of the first cross winding portion 12 and the second cross winding portion 14. Furthermore, the underneck winding portion 11, the electric wire winding portion 13, and the exterior material winding portion 13A are formed by winding the tape 4 around the underneck portion 211, the electric wire 3, or the exterior material 101 two times, but the tape 4 may be wound one time or three or more times.
