{Embodiment}
Hereinafter, a manufacturing method of an electric wire with a connector and electric wire 10 with a connector concerning an embodiment are explained. FIG. 1 is a schematic perspective view showing an electric wire 10 with a connector, and FIG. 2 is a schematic cross-sectional view showing the electric wire 10 with a connector.

  The electric wire with connector 10 includes a connector 30, a plurality of electric wires 20, and a covering portion 40. Furthermore, here, the connector-attached electric wire 10 includes an interposition part 50. The electric wire with connector 10 is used as a wiring material in a vehicle, for example.

  The connector 30 is a member molded by an insulating material such as a resin, and has a rectangular parallelepiped appearance here. The connector 30 is formed with a plurality of cavities 32 (see FIG. 3) penetrating from the distal end side (side connected to the mating connector) to the proximal end side (opposite the distal end). Usually, the plurality of cavities 32 are formed to be aligned in the width direction of the connector 30. The plurality of cavities 32 may be formed in a plurality of rows in the vertical direction of the connector 30 or may be formed in only one row. A terminal is accommodated and held in the cavity 32. And the connector in the cavity 32 of this connector 30 and the terminal by the side of the other party connector are connected by this connector 30 and the other party connector being connector-connected.

  The electric wire 20 is configured such that a covering portion is formed by extrusion coating or the like of an insulating resin on the outer periphery of a conductive core wire. The core wire is formed using aluminum or an aluminum alloy as a material. However, the core wire may be formed using other metals such as copper or copper alloy as a material. The electric wire 20 is used to electrically connect various electric devices mounted on a vehicle or the like in a state where the electric wire 20 is disposed at an arrangement target location of the vehicle or the like.

  At the end portion of the electric wire 20, the covering portion is removed and the core wire is exposed for a predetermined length. A terminal is crimped to the exposed core wire. The terminal is formed using copper, tin or the like as a main material. But the terminal may be formed from other metals, such as aluminum.

  The terminal includes a wire fixing part and a connection part. The electric wire fixing part is constituted by a coated crimping part that is crimped to the coating part of the electric wire 20 and a core wire crimping part that is crimped to the core wire. A connection part is a part electrically connected with the other party's terminal. The connecting portion may have a cylindrical female terminal shape, or may have a tab-shaped or pin-shaped male terminal shape.

  The terminal is inserted into the cavity 32 from the proximal end side of the connector 30 while being connected to the end of the electric wire 20, and is locked and fixed in the cavity 32. In this state, the plurality of electric wires 20 extend outward through the openings of the cavities 32 on the proximal end side of the connector 30. Therefore, the position where the plurality of electric wires 20 extend from the base end side of the connector 30 is defined by the position of the opening of the cavity 32. Normally, the cavities 32 are formed side by side along the width direction of the connector 30, so that a part of the plurality of electric wires 20 extends from a position from one side of the base end portion of the connector 30, and the plurality of electric wires 20. The other part extends from a position from the other side of the base end portion of the connector 30. For this reason, when the plurality of electric wires 20 are tightly bundled on the proximal end side of the connector 30, the electric wires 20 extending from the position on the side of the proximal end portion of the connector 30 are strongly pressed against the opening of the cavity 32. In particular, when the connector 30 is wide, such a problem is likely to occur. The present embodiment relates to a technique for suppressing the electric wire 20 from being strongly pressed against the opening of the cavity 32 as described above. Hereinafter, the electric wires 20 extending from positions on both sides of the connector 30 in the electric wires 20 are referred to as outer electric wires 20a.

  The covering portion 40 is formed by winding a tape 42 in a spiral shape so as to cover a portion extending from the connector 30 to the electric wire 20.

  The covering portion 40 plays a role of suppressing water from entering the connector 30 from the base end side of the connector 30.

  In addition, when the core wire and the terminal of the electric wire 20 are formed of different metals, the different metal contact corrosion is likely to occur at the connection portion. In order to avoid this, it is preferable that water does not adhere to the connecting portion between the core wire and the terminal. Therefore, the structure which covers the connection part of a core wire and a terminal by mold shaping | molding, application | coating of an anticorrosive, etc. is also considered. However, in that case, it is necessary to perform anticorrosion processing on the connection portion between each electric wire 20 and the terminal, resulting in an increase in cost. Therefore, if the covering portion 40 is formed so as to cover the portion extending between the connector 30 and the electric wire 20, it is possible to suppress water intrusion at the base end side of the connector 30 at a low cost, and anti-corrosion measures can be taken at low cost. It becomes possible. As described above, when the core wire and the terminal of the electric wire 20 are formed of different metals, the configuration according to the present embodiment is effective as a configuration for performing anticorrosion. But the structure which concerns on this embodiment is applicable also when the core wire and terminal of the electric wire 20 are formed with the same kind of metal.

  The covering portion 40 is formed by spirally winding the tape 42 so as to overlap the outer peripheral side so as to cover a portion extending from the connector 30 to the electric wire 20. At this time, the covering portion 40 is formed by spirally winding the tape 42 so as to sequentially overlap the outer peripheral side from the electric wire 20 toward the connector 30. Further, the covering portion 40 is wound around the outer peripheral side of the interposition portion 50.

  The interposition part 50 is formed by winding the tape 52 around a portion of the plurality of electric wires 20 that extends from the connector 30. The interposition part 50 is provided in order to relieve the force with which the tape 42 constituting the covering part 40 presses the electric wire 20.

  The interposition part 50 is provided partially or entirely on the inner peripheral side of the covering part 40. When the interposition part 50 is provided entirely on the inner peripheral side of the covering part 40, the tape 52 is wound spirally to constitute the interposition part 50. In this case, the intervening portion 50 includes a portion of the tape 52 wound spirally that is continuously wound so that adjacent tapes 52 do not overlap each other. The configuration of the interposition part 50 is that the interposition part 50 is formed by winding the tape 52 around the electric wire 20 in a state where the surface facing the inner side in the width direction of the outer electric wire 20a is in contact with the contact part 70. by.

  Here, the interposition part 50 is provided continuously from the assembly part 28 to the connector 30 described later. Details of the interposition part 50 will be described later.

  A method for manufacturing the connector-attached electric wire 10 will be described.

  First, as shown in FIG. 3 to FIG. 5, a connector in which a plurality of electric wires 20 extend to the proximal end side of the connector 30 is prepared. At this time, the surface of the outer electric wire 20a facing the inner side in the width direction is brought into contact with the contact portion 72 (step (a)). In the initial state, the plurality of electric wires 20 extend to the proximal end side of the connector 30 at positions corresponding to the openings of the cavities 32. 3 to 5, a state in which the plurality of electric wires 20 extend in parallel from the base end portion of the connector 30 is illustrated.

  At this time, it is assumed that the connector-attached electric wire 10 is manufactured on the assembly drawing board 60. The assembly drawing board 60 is provided with an upright connector holder 80 for holding the connector 30 and an electric wire support 90 for supporting the electric wire 20. Further, here, an abutting jig 70 that abuts on the inward surface of the outer electric wire 20 a is also provided upright on the assembly drawing board 60.

  The connector holder 80 may include, for example, a holding portion 82 that holds the connector 30 and a drawing plate fixing portion 84 that has one end connected to the holding portion 82 and the other end fixed to the assembly drawing plate 60. The holding portion 82 is formed with a recess having an inner surface shaped along the outer surface of the connector 30. The holding portion 82 can hold the connector 30 by fitting the connector 30 into the concave portion from the distal end side. At this time, the connector 30 is held by the connector holder 80 in such a manner that a part of the base end side slightly protrudes from the holding portion 82. Thereby, when forming the covering portion 40 or forming the interposition portion 50, the tape 42 (52) can be wound around the proximal end portion of the connector 30 while the connector 30 is held by the connector holder 80. .

  The wire support 90 is provided at a position away from the connector holder 80. Here, the connector 30 is provided at a position spaced apart from the connector holder 80 along the extending direction of the electric wire 20 extending from the connector 30 with the connector 30 held by the connector holder 80. Here, the electric wire support 90 supports all the electric wires 20 extending from the connector 30. The wire support 90 includes, for example, a support portion 92 formed in a U shape so as to support the wire 20, and a drawing plate fixing portion 94 that has one end connected to the support portion 92 and the other end fixed to the assembly drawing plate 60. It is possible to include.

  The abutting jig 70 connects two abutting portions 72 that can abut against the outer electric wire 20a, and two abutting portions 72 on one end side, and is fixed to the assembly drawing plate 60 on the other end side. A fixing portion 74. The contact jig 70 is provided so that the two contact portions 72 are located outside the proximal end of the connector 30 held by the connector holder 80. Here, the abutting jig 70 is located between the electric wire support 90 and the connector 30 held by the connector holder 80 so that the two abutting portions 72 are located at positions spaced from each other. Is provided.

  Here, the two abutting portions 72 are formed in a rod shape having a square cross section. The two contact portions 72 are provided so as to be able to contact the surface of the outer electric wire 20a facing the inner side in the width direction. Specifically, the distance between the surfaces of the two abutting portions 72 facing outward in the width direction is larger than the width dimension of the bundle of wires 20 assembled at the assembly position of the outer wires 20a (here, the outer wires 20a are inserted). The distance between the cavities 32 on both sides of the connector 30 is set to the same level). For this reason, the outer side electric wire 20a extended from the connector 30 contacts the contact part 72 on the way to the assembly position. When the outer electric wire 20a abuts against the abutting portion 72, the inclination of the outer electric wire 20a from the base end portion of the connector 30 to the abutting portion 72 becomes gentler than the inclination from the abutting portion 72 to the gathering position. . The interval between the surfaces of the two contact portions 72 facing outward in the width direction may be constant or changeable.

  Next, the tape starts to be wound around the electric wire 20 while keeping the contact portion 72 in contact with the outer electric wire 20a, and the tape 42 is spirally wound around the portion extending from the connector 30 to the electric wire 20. The part 40 is formed (step (b)).

  In this case, the interposition part 50 is formed prior to the covering part 40 in order to explain an example in which the interposition part 50 is formed. That is, in the step (b), with the outer wire 20 a kept in contact with the contact portion 72, the tape 52 is wound around at least the portion between the connector 30 and the contact portion 72 of the wire 20. The part 50 is formed (step (b1)). Then, after the step (b1), the outer electric wire 20a is separated from the contact portion 72, and the covering portion 40 is formed outside the interposition portion 50 (step (b2)).

  Further, here, in the step (b1), the tape 52 is wound so as to cross between the two contact portions 72 while keeping the two contact portions 72 in contact with the outer electric wire 20a. Thus, the interposition part 50 is formed. At this time, the intervening portion 50 is formed by winding the tape 52 so as to cross at least twice (here, twice) in a manner of crossing the two abutting portions 72 with each other.

  Specifically, first, as shown in FIG. 6, the tape 52 is started to be wound in order to form the interposition portion 50 while keeping the contact portion 72 in contact with the outer electric wire 20 a. Here, the tape 52 starts to be wound from a position farther from the contact portion 72 than the connector 30. The winding start position is a position (collection position) where the plurality of electric wires 20 gather. Hereinafter, a portion of the plurality of electric wires 20 that is gathered at the gathering position is referred to as a gathering portion 28. When the tape 52 is wound in this way, the outer electric wire 20a extends from the opening of each cavity 32 to the abutting portion 72 while being inclined straightly or gently, and at the same time the inclined portion is greatly inclined from the abutting portion 72. The posture extends toward 28.

  In addition, it is preferable to perform the tape winding operation in a state where the connector 30 and the gathering portion 28 are pulled apart. This is because the posture of the electric wire 20 can be further stabilized. However, since the electric wire 20 itself has a certain degree of strength that is difficult to bend, as described above, the posture of the electric wire 20 is stabilized to some extent even if it is not in such a pulled state if the gathering portion 28 is fixed. Can be made. For this reason, it is not essential to perform the tape winding operation in a state where the connector 30 and the collective portion 28 are pulled apart.

  Here, if the outer electric wire 20a is not in contact with the contact portion 72, it is considered that the outer electric wire 20a extends with a substantially constant inclination from the base end side of the connector 30 toward the gathering position. In this state, when the tape was wound, the outer electric wire 20a was fixed by the tape in a state of being largely inclined even on the proximal end side of the connector 30 and the outer electric wire 20a was strongly pressed against the opening of the cavity 32. It is conceivable that the state is maintained.

  On the other hand, as described above, when the outer electric wire 20a is brought into contact with the contact portion 72, the inclination from the proximal end portion of the connector 30 to the contact portion 72 in the outer electric wire 20a is changed to the outer electric wire 20a. Is gentler than the inclination from the connector 30 to the assembly position when the contact portion 72 is not in contact with the contact portion 72. For this reason, even if the tape 42 is wound around the base end side of the connector 30, the electric wire 20 is not easily inclined, and the electric wire 20 is maintained in a state of being strongly pressed against the opening of the cavity 32. Is unlikely to occur.

  If the outer electric wire 20a is not in contact with the contact portion 72, the outer electric wire 20a can freely move with the opening peripheral edge of the cavity 32 as a fulcrum when the tape is wound. For this reason, the outer side electric wire 20a may be largely inclined by the winding force at the time of winding the tape, the operator's unintended contact with the outer side electric wire 20a, and the like. In this state, when the tape is wound, the outer electric wire 20a is fixed with the tape in a largely inclined state, and the outer electric wire 20a is maintained in a state of being strongly pressed against the opening of the cavity 32. Conceivable.

  On the other hand, as described above, when the outer electric wire 20a is in contact with the contact portion 72, a portion of the outer electric wire 20a from the connector 30 toward the assembly portion 28 (particularly, from the connector 30 to the contact portion 72). The state (inclined state) of the portion facing toward is stabilized. For this reason, even if the tape 52 (42) is wound around the portion, the electric wire 20 is not easily inclined, and the electric wire 20 is kept pressed against the opening of the cavity 32. It is hard to occur.

  Next, as shown in FIG. 7, the tape 52 is wound so as to cross between the two contact portions 72 while keeping the contact portion 72 in contact with the outer electric wire 20 a. More specifically, when the tape 52 is further wound from the state of FIG. 6 toward the connector 30, it reaches a portion where the outer electric wire 20 a and the contact portion 72 are in contact. In this portion, the tapes 52 cannot be overlapped and wound spirally while the contact portion 72 is kept in contact with the outer electric wire 20a. For this reason, in this portion, the contact portion 72 is sandwiched by winding the tape 52 so as to cross between the two contact portions 72 while keeping the contact portion 72 in contact with the outer electric wire 20a. The tape 52 can be wound so as to be continuous on both sides. Hereinafter, a portion of the interposition portion 50 where the tape 52 is wound so as to cross between the two contact portions 72 is referred to as an oblique winding portion 54. The oblique winding portion 54 is a portion in which the tapes 52 are spirally wound in a manner in which the tapes 52 are spaced apart in the width direction.

  After that, the tapes 52 are overlapped to the periphery of the base end side of the connector 30 exposed from the connector holder 80 as it is, and the result is as shown in FIG. Here, it is considered that the formation of the interposition part 50 is completed in the state of FIG.

  In addition, you may form another diagonal winding part 54 in the outer peripheral side of the said diagonal winding part 54. FIG. Specifically, as shown in FIG. 9, the oblique winding portion 54 is formed so as to intersect the oblique winding portion 54. Thereby, in the vicinity of the contact portion 72 in the interposition portion 50, the tape 52 is wound in an X shape. Hereinafter, the diagonally wound portion 54 that is located on the innermost peripheral side is the first obliquely wound portion 54a, and the obliquely wound portion 54 that intersects the first obliquely wound portion 54a on the outer peripheral side of the first obliquely wound portion 54a. Is referred to as a second diagonally wound portion 54b.

  Here, the tape 52 constituting the second oblique winding portion 54b may or may not be continuous with the tape 52 constituting the first oblique winding portion 54a. As a winding method in which the tape 52 constituting the second oblique winding portion 54b is continuous with the tape 52 constituting the first oblique winding portion 54a, for example, as shown in FIG. 7 or FIG. It is conceivable to wind the tape 52 toward the gathering portion 28 side after forming the first slant winding portion 54a so as to face the connector 30 with the contact portion 72 interposed therebetween. Further, as a winding method in which the tape 52 constituting the second oblique winding portion 54b is not continuous with the tape 52 constituting the first oblique winding portion 54a, for example, as shown in FIG. 7 or FIG. It is conceivable to wind the tape 52 once after forming the winding portion 54a, and then start winding again to form the second oblique winding portion 54b.

  In addition, when winding the tape 52 so as to cross between the two contact portions 72, for example, if the tip of the contact portion 72 is set so as not to protrude outward from the electric wire 20, the following There are advantages. That is, even when the tape 52 is wound so as to pass above the contact portion 72 when crossing between the two contact portions 72, the tape 52 is wound obliquely at the interposition portion 50 after being removed from the contact portion 72. A part becomes difficult to bend.

  After the formation of the interposition part 50 is finished, the covering part 40 is formed next. The covering portion 40 is formed by spirally winding the tape 42 so as to overlap the outer peripheral side so as to cover a portion extending from the connector 30 to the electric wire 20. Here, it is assumed that the tape 42 is spirally wound from the electric wire 20 toward the connector 30. Here, the covering portion 40 is formed on the outer peripheral side of the interposition portion 50.

  In addition, as the tape 42, the adhesive tape in which the adhesion layer was formed in the one main surface of the strip | belt-shaped base material formed with resin etc. can be used. At this time, the tape 42 constituting the covering portion may be the same type of tape as the tape 52 constituting the interposition portion, or may be a different type of tape. Here, the tape 42 and the tape 52 will be described as being the same type of tape.

  When the connector-attached electric wire 10 wound with the tape 42 in this way is observed in a cross section along the extending direction of the electric wire 20, it is as shown in FIG. In this cross section, each winding layer portion of the tape 42 is continuous so as to incline downward from the outer peripheral portion of the base end portion of the connector 30 toward the outer peripheral portion of the bundle of the electric wires 20 away from the base end portion of the connector 30. . Further, when observing the mutual relationship between the respective winding layer portions of the tape 42, the winding layer portion close to the connector 30 partially overlaps the outer peripheral side with respect to the winding layer portion farther from the connector 30 than this. For this reason, even if a gap is generated between the respective wound layer portions of the tape 42, the gap is opened on the side away from the connector 30. For this reason, when water flowing from the connector 30 to the electric wire 20 side is observed, the water hardly penetrates into the inside through a gap between the winding layer portions, and smoothly flows to the electric wire 20 side through the surface of each winding layer portion. Go. For this reason, the electric wire 10 with a connector can easily infiltrate water from the base end side of the connector 30 when the connector 10 is disposed in a horizontal posture or an inclined or vertical posture with the connector 30 facing upward from the horizontal posture. It can be effectively suppressed.

  As described above, according to the method for manufacturing the electric wire with connector and the electric wire 10 with connector according to the present embodiment, in a state where the outer electric wire 20a abuts against the abutting portion 72 and maintains a stable posture to some extent, the tape (here, The winding of the tape 52) begins. For this reason, even after the covering portion 40 is formed, the electric wire 20 can be maintained in a state where it gently extends as far as possible from the connector 30 at the edge portion of the connector 30. As a result, the winding force of the tape 42 is less likely to act as a force that presses the electric wire 20 against the opening peripheral edge of the cavity 32 of the connector 30 with a large force, and the electric wire 20 extending to the proximal end side of the connector 30 It is possible to prevent the connector 30 from being pressed with a large force against the peripheral edge of the opening of the cavity 32.

  Further, in order to form the interposition part 50 by winding the tape 52 around at least the connector 30 and the contact part 72 of the electric wire 20 while keeping the outer wire 20a in contact with the contact part 72. The force that the tape 42 constituting the covering portion 40 brings the electric wire 20 toward the center of the connector 30 can be relaxed by the interposition portion 50. Further, after the formation of the interposition part 50, the outer wire 20 a is separated from the abutment part 72, and the covering part 40 is formed outside the interposition part 50. It is possible to easily achieve both.

  Further, the tape 52 is wound so as to cross between the two contact portions 72 while maintaining the state where the two contact portions 72 are in contact with the outer electric wires 20a, respectively, and the oblique winding portion 54 of the interposition portion 50 is formed. In order to form, the interposition part 50 is continuously formed in the part from the base end side of the connector 30 to a gathering position among the electric wires 20, with the two contact parts 72 kept in contact with the outer electric wires 20a. be able to.

  Further, the tape 52 is wound so as to cross at least twice between the two contact portions 72 so as to cross each other, thereby forming the first oblique winding portion 54a and the second oblique winding portion 54b. The strength of 50 can be improved.

  Further, since the contact jig 70 including the contact portion 72 is fixed to the assembly drawing plate 60, the contact portion 72 can be provided with a simple configuration.

{Modifications}
In the embodiment, it is described that the interposition part 50 is provided, but this is not essential, and the interposition part 50 may not be provided. Even when the interposition part 50 is not provided, the tape 42 is wound around the abutment portion 72 of the electric wire 20 by appropriately adjusting the position where the abutment portion 72 abuts the outer electric wire 20a. Even if the covering portion 40 is formed after separating the unexposed portion from the contact portion 72, the outer electric wire 20 a can be prevented from being bent as much as possible by the opening of the cavity 32. Therefore, the outer electric wire 20a can be kept in an inclined state so as not to be strongly pressed against the opening of the cavity 32.

  Further, even when the interposition part 50 is provided, it is not essential that the interposition part 50 includes the oblique winding portion 54. For example, the interposition part 50 is formed only in a portion between the contact part 72 and the connector 30 in the electric wire 20 in a state where the outer electric wire 20a is in contact with the contact part 72 as shown in FIG. It is also possible that

  Further, even when the interposition part 50 includes the oblique winding part 54, it is not essential that the tape 52 is continuously wound without interruption from the assembly position to the connector 30. For example, as shown in FIG. 10, after the interposition part 50 is partially formed at the gathering position and the base end side of the connector 30, the oblique winding part 54 may be formed so as to cross the contact part 72. .

  Further, in the embodiment, the portion other than the oblique winding portion 54 in the interposition portion 50 has been described as being wound with the tapes overlapped, but this is not essential. It is also conceivable that the portions other than the diagonally wound portions of the intervening portions are wound so that the tapes do not overlap each other.

  In the embodiment, the contact portion 72 is described as being formed in a rod shape having a square cross section, but this is not essential. For example, like the contact portion 72A shown in FIG. 11, the contact portion may be formed in a rod shape having a circular cross section. In this case, the well-known electric wire support tool formed in the said U shape as the contact jig | tool 70A can also be used.

  In the embodiment, the two contact portions 72 are described as being connected on the proximal end side, but this is not essential. For example, the two contact portions may be fixed to the assembly drawing board 60 without being connected. In this case, it is conceivable that two bar-like members are provided upright on the assembly drawing plate 60, and the tip ends of the two bar-like members form two contact portions.

  In the embodiment, the two contact portions 72 are described as being fixed to the assembly drawing plate 60 via the drawing plate fixing portion 74, but this is not essential. For example, the contact portion may be provided so as to protrude from the connector holder 80 that holds the connector 30. Thereby, the contact part 72B can be provided with a simple configuration. In this case, the contact portion 72B may be detachable from the connector holder 80 or may not be detachable. In the example shown in FIG. 12, the contact portion 72 </ b> B is provided so as to protrude from the connector holder 80 via a connecting portion 88 connected to the contact portion 72 </ b> B on one end side and to the connector holder 80 on the other end side. . Under the present circumstances, about the part which is located between the contact part 72B and the connector holder 80 among the connection parts 88, and overlaps with the electric wire 20 and the connector 30 which protrudes from the connector holder 80 in planar view, the electric wire 20 And it is good to arrange | position away from the connector 30. FIG. Thereby, even if there exists the connection part 88, the operation | work which winds the tape 52 (42) to the part located between the contact part 72B and the connector holder 80 among the electric wires 20, and the base end side of the connector 30 is performed. Can do. Note that the two abutting portions 72B may be integrated by the connecting portion 88 or may be separate.

  In addition, each structure demonstrated by the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
