It is a schematic perspective view which shows the wire harness which concerns on embodiment. It is a schematic longitudinal cross-sectional view which shows a wire harness. It is explanatory drawing which shows the manufacturing process of a wire harness. It is explanatory drawing which shows the manufacturing process of a wire harness. It is explanatory drawing which shows the manufacturing process of a wire harness.

  Hereinafter, the wire harness 10 according to the embodiment will be described. FIG. 1 is a schematic perspective view showing the wire harness 10, and FIG. 2 is a schematic longitudinal sectional view showing the wire harness 10. 1 and 2 show a portion of the wire harness 10 where the connector fixing member 20 is provided.

  The wire harness 10 includes a wire harness main body 12 and a connector fixing member 20.

  The wire harness main body 12 is configured by bundling a plurality of electric wires 12a. Usually, the wire harness main-body part 12 is bundled, the some electric wire 12a branching according to the wiring form in a vehicle. Moreover, the connector is attached to the edge part of each electric wire 12a. And in the state where this wire harness main-body part 12 was arrange | positioned along the predetermined wiring form in a vehicle, each electric component connected this electric wire harness main-body part 12 by connecting a various electrical component in a vehicle. Are electrically connected to each other.

  The wire harness main body 12 includes a main line portion 13 and a branch line portion 14. The trunk portion 13 is usually a portion where a plurality of electric wires are bundled, but may be a portion including only one electric wire. The branch line portion 14 is constituted by an electric wire 12 a that branches from the middle of the main line portion 13. Although an example in which one electric wire 12a is branched from the main line portion 13 will be described here, a plurality of electric wires 12a may be branched from the main line portion 13. Further, the main line portion 13 may be branched at a place other than the place where the main branch line portion 14 is provided. The wire harness main body 12 may include an optical cable or the like.

  A connector part 16 is attached to the end of the branch line portion 14. This connector component 16 is used, for example, for connection with an electrical component (not shown) that is optionally installed on the vehicle. Therefore, when this electrical component is not used, the connector component 16 is attached and fixed to the main line portion 13 without being connected to another connector (not shown). When the electrical component is additionally equipped, the connector component 16 is removed from the main line portion 13 and connected to the connector connected to the electrical component. Here, the connector component 16 is formed in a rectangular parallelepiped shape. On the outer periphery of the connector component 16, a lock structure for locking and fixing to the mating connector may be formed.

  The connector component 16 may be a connector incorporating an electrical component such as a diode or a fuse in addition to the optional connector as described above. These connectors are provided for the purpose of mounting an electrical component such as a diode or a fuse in the middle path of the wiring of the wire harness main body 12.

  The connector fixing member 20 is a member formed by hot pressing a non-woven member, and includes a wire harness attaching portion 22 and a connector holding portion 26. The connector fixing member 20 is preferably formed at a location where the connector component 16 is disposed in a state where the branch line portion 14 is disposed along the main line portion 13.

  Here, the non-woven member used for forming the connector fixing member 20 will be described. As the non-woven member, one that can be hardened through a heating step can be used. As such a non-woven member, a material including a basic fiber and an adhesive resin (also called a binder) intertwined with the basic fiber can be used. The adhesive resin is a resin having a melting point (for example, 110 ° C. to 115 ° C.) lower than the melting point of the basic fiber. When the nonwoven member is heated to a processing temperature lower than the melting point of the basic fiber and higher than the melting point of the adhesive resin, the adhesive resin melts and penetrates between the basic fibers. Thereafter, when the nonwoven member has a temperature lower than the melting point of the adhesive resin, the adhesive resin is solidified in a state where the basic fibers are bonded to each other. Thereby, the nonwoven member becomes harder than the state before heating, and is maintained in the molded shape at the time of heating. Further, in a portion where the nonwoven members are in contact with each other, the molten adhesive resin is also infiltrated into the contact portion and solidifies. Thereby, the contact part of nonwoven members is joined.

  However, the basic fiber may be any fiber that can maintain the fiber state at the melting point of the adhesive resin, and various fibers can be used in addition to the resin fiber. As the adhesive resin, thermoplastic resin fibers having a melting point lower than that of the basic fiber can be used. The adhesive resin may be granular or fibrous. Alternatively, an adhesive resin layer may be formed on the outer periphery of the core fiber to form a binder fiber, which may be entangled with the basic fiber. As the core fiber in this case, the same material as the basic fiber can be used.

  Examples of the combination of the basic fiber and the adhesive resin include an example in which the basic fiber is a resin fiber of PET (polyethylene terephthalate) and the adhesive resin is a copolymer resin of PET and PEI (polyethylene isophthalate). In this case, the melting point of the basic fiber is approximately 250 ° C., and the melting point of the adhesive resin is 110 ° C. to 150 ° C. For this reason, when the nonwoven member is heated to a temperature of 110 ° C. to 250 ° C., the adhesive resin is melted and soaked between the basic fibers that keep the fiber shape without melting. And when a nonwoven member becomes temperature lower than melting | fusing point of adhesive resin, adhesive resin solidifies in the state which couple | bonded basic fibers, The maintenance of the said shaping | molding shape and joining of nonwoven members are performed.

  Moreover, hot press means performing the heat processing with respect to a nonwoven member, and the process which presses a nonwoven member to a type | mold, and forms in a predetermined shape. The heat treatment and the forming process into a predetermined shape may be performed simultaneously, or may be performed separately continuously. For example, after heating a nonwoven member, you may press with a predetermined type | mold before solidifying by cooling. An example of hot pressing suitable for processing the connector fixing member 20 according to this embodiment will be described in detail later.

  The wire harness attachment part 22 is attached and fixed to the main line part 13 in a state of covering at least a part of the main line part 13. That is, when the nonwoven member is hot-pressed with the nonwoven member covering a part of the trunk portion 13, the nonwoven member is cured in a shape covering the trunk portion 13 and the adhesive resin inside is melted. By fixing to the surface of the trunk portion 13, the wire harness attachment portion 22 is attached and fixed at a fixed position with respect to the wire harness main body portion 12. The wire harness main body part 12 and the wire harness attachment part 22 may be fixed by a double-sided tape between them.

  In addition, since the wire harness attachment part 22 itself has hardened in the state which covered the wire harness main-body part 12, it also has a function which performs the protection of the wire harness main-body part 12, and the path | route control of the wire harness main-body part 12. Yes. In view of these functions, the wire harness attachment part 22 may cover a longer part of the wire harness main body part 12 or the whole.

  The connector holding part 26 is a part formed integrally with a part around the outer periphery of the wire harness attaching part 22, and a holding concave part 28 is formed in the connector holding part 26. That is, when forming the wire harness attachment portion 22, the connector holding portion 26 is formed by hot pressing into a predetermined shape of the connector holding portion 26 using a non-woven member at a side portion thereof.

  The holding recess 28 is a bottomed recess that opens to one side, and is formed in a shape that gradually narrows from the opening 28a toward the back side.

  More specifically, the holding recess 28 opens in a direction along the longitudinal direction of the main line portion 13. In other words, it is formed in a bottomed concave shape that is recessed from the opening 28 a facing one side in the longitudinal direction of the main line portion 13 to the other side in the longitudinal direction of the main line portion 13. Here, a part of the trunk portion 13 is exposed in the holding recess 28, three of the outer circumferences of the holding recess 28 are surrounded by the non-woven member, and the other one is surrounded by the outer circumference of the trunk portion 13. being surrounded. However, the entire four sides of the outer periphery of the holding recess 28 may be surrounded by the non-woven member.

  The holding recess 28 has portions corresponding to the three side surfaces of the outer peripheral surface shape of the quadrangular pyramid obtained by cutting off the top of the quadrangular pyramid. Therefore, the cross-sectional shape in the direction orthogonal to the depth direction is square. It is formed so as to exhibit a shape. Here, the inner side surface 28c facing the main line portion 13 of the inner peripheral surface of the holding recess 28 is formed in a slope shape that gradually narrows the inner space from the opening toward the inner side. As a result, when the rectangular parallelepiped connector component 16 is inserted into the main holding recess 28, a straight edge on the opposite side of the trunk portion 13 from the tip portion (the portion on the opposite side to the side where the electric wire 12a extends). The portion comes into contact with the inner side surface 28c in a linear manner.

  Further, the size of the opening 28 a of the holding recess 28 is formed larger than the size of the distal end portion of the connector component 16. Here, the opening 28 a is formed in a rectangular shape that is larger than the size of the tip of the connector component 16. Further, the holding recess 28 gradually narrows from the opening 28a toward the inner side thereof, and is narrowed to be smaller than a size capable of pressing the connector part 16.

  Here, the width dimension of the opening 28a is set to be equal to or larger than the width dimension of the connector part 16, and the height dimension H1 of the opening 28a is set larger than the height dimension H3 of the connector part 16. Accordingly, the distal end portion of the connector component 16 can be easily inserted into the opening 28a.

  The width direction of the holding recess 28 (the circumferential direction of the wire harness main body 12) is set to the same size from the opening 28a side to the back side of the holding recess 28. Further, the inner side surface 28c of the holding recess 28 is inclined as described above, and the height dimension of the holding recess 28 (the radial dimension of the wire harness main body 12) is directed from the opening 28a side to the back side. The height H2 of the bottom 28b of the holding recess 28 is set to be gradually smaller, and is smaller than the height H3 of the connector part 16. Therefore, the height dimension of the holding recess 28 coincides with the height dimension H3 of the connector component 16 between the opening 28a and the bottom 28b of the holding recess 28, preferably at a position from the bottom 28b. At this location, the connector component 16 is pressed toward the main line portion 13 by the inner peripheral surface of the holding recess 28.

  In the above embodiment, the height of the holding recess 28 is gradually reduced from the opening 28a side to the back side, but both the height dimension and the width dimension or only the width dimension from the opening to the back side. You may make it small gradually toward the side.

  Further, the depth dimension L1 of the holding recess 28 is set larger than the length dimension L3 of the connector part 16. Further, the connector component 16 is inserted into the holding recess 28 as described above, and the tip end portion of the connector component 16 is pressed by the inner side surface 28c of the holding recess 28, so that the gap between the pressing portion and the opening 28a is reduced. The dimension L2 is set to be the same as or larger than the length dimension L3 of the connector part 16. Thus, the connector part 16 can be entirely covered by the connector holding part 26 in a state where the connector part 16 is inserted into the holding recess 28. However, the base end portion of the connector component 16 may partially protrude from the holding recess 28 in a state where the connector component 16 is inserted into the holding recess 28.

  Then, the connector component 16 is inserted into the holding recess 28 through the opening 28 a, and the distal end portion of the connector component 16 is disposed between the outer peripheral portion of the main line portion 13 and the inner side surface 28 c of the holding recess 28. When the connector component 16 is further pushed in this state, the tip end portion of the connector component 16 contacts the inner side surface 28c of the holding recess 28, and the inner side surface 28c of the holding recess 28 is slightly elastically deformed outward. When the pushing force of the connector part 16 is removed, the inner side surface 28c of the holding recess 28 is elastically restored to its original shape, and the distal end portion of the connector part 16 is connected to the outer peripheral portion of the main line portion 13 and the inner side surface 28c of the holding recess 28. The connector part 16 is held in the holding recess 28. In addition, the inner side surface 28c of the holding recess 28 is a surface obtained by hot pressing a non-woven member, and exhibits a surface property in which fibers are entangled with each other. In particular, in an example formed by a manufacturing method example to be described later, the inner side surface 28c of the holding recess 28 is not a directly heated surface, and thus exhibits a surface property in which fibers are often entangled. For this reason, the front-end | tip part of the connector component 16 is hold | maintained even if it embeds in the inner side surface 28c of the holding | maintenance recessed part 28, and it is hard to remove | deviate from the inner side surface 28c.

  A manufacturing example of the wire harness 10 will be described.

  First, as shown in FIG. 3, the wire harness body 12 including the main line portion 13, the branch line portion 14, and the connector component 16 is prepared. The wire harness main body 12 may be bound at another location or may not be bound. Then, a non-woven member 50, in this case, an elongated rectangular sheet-like non-woven member 50 is wound around a part of the main line part 13, and a part of the main line part 13 is covered with the non-woven member 50.

  A core die 55 is disposed in the non-woven member 50. The core die 55 is formed in a shape corresponding to the inner peripheral shape of the holding recess 28, more specifically, a shape exhibiting the outer peripheral surface shape of a quadrangular pyramid with the top of the quadrangular pyramid cut out. Here, the core die 55 is in contact with a part around the outer periphery of the main wire portion 13 in a posture in which the bottom surface on the wide side of the core metal die 55 is oriented in one direction along the longitudinal direction of the main wire portion 13. It is arranged as follows. Then, the non-woven member 50 is wound around the core die 55 and the trunk portion 13 so that the bottom surface is exposed to the outside. When winding the non-woven member 50, a double-sided tape may be affixed to the beginning and end of winding to temporarily hold the winding state.

  Note that the core die 55 may be inserted between the main line portion 13 and the non-woven member 50 after the non-woven member 50 is wound. Further, when the non-woven member 50 is wound around the trunk portion 13 a plurality of times, a core die 55 may be disposed between the layers of the non-woven member 50.

  Next, hot pressing is performed. Here, a configuration example of a hot press mold will be described. 4 and 5 are explanatory views showing the processing work by the hot press mold 60. FIG.

  The hot press mold 60 includes a lower mold 62 and an upper mold 72.

  The lower mold 62 is a long member formed of a metal or the like excellent in thermal conductivity, and a lower mold surface 63 is formed on one main surface (upper surface) thereof. The lower mold surface 63 is generally formed in a groove shape whose bottom portion has a semi-cylindrical surface shape and opens upward. The length of the lower mold surface 63 in the longitudinal direction is set to be equal to or longer than the length dimension of the connector fixing member 20. The lower mold surface 63 is formed in a shape extending according to a route when the protection target portion in the wire harness main body 12 is disposed on the vehicle body (in FIG. 4 and FIG. 5, the lower mold surface 63 is linear). Yes, but it can be curved.) In addition, a concave portion 64 for forming the connector holding portion 26 is formed on one side portion of one end portion in the longitudinal direction of the lower mold surface 63. The concave portion 64 is formed in a concave shape having a shape that follows the outer side surface and one side surface of the outer shape of the connector holding portion 26, and is also opened above the concave shape.

  The upper die 72 is a long member formed of a metal or the like having excellent thermal conductivity, and an upper die having a groove shape that is open on the one main surface (lower surface) of which the upper portion has a semi-cylindrical surface shape. A surface 73 is formed. The upper mold surface 73 is formed to have a width that can be disposed in the lower mold surface 63 while closing the upper opening of the lower mold surface 63. Further, the upper mold surface 73 is formed in a shape extending in accordance with the path according to the bent shape of the lower mold surface 63. In addition, a protrusion 74 that protrudes to the side of the upper mold surface 73 and closes the upper opening of the recess 64 is located at one side of one longitudinal end of the upper mold surface 73 and facing the recess 64. Is formed. The protrusion 74 has a downward surface in a shape that follows the other side surface of the outer shape of the connector holding portion 26.

  The upper mold surface 73 and the protrusion 74 are disposed in the lower mold surface 63 and the recess 64, so that a space in which the connector fixing member 20 can be formed is formed between them. The lower mold 62 and the upper mold 72 are provided with a heating unit such as a heater.

  A method for performing hot pressing using the hot pressing mold 60 will be described.

  That is, the portion of the wire harness main body 12 where the non-woven member 50 is wound is pushed into the lower mold surface 63. At this time, the core die 55 and the portion of the non-woven member 50 covering it are pushed into the recess 64. At this time, even when the arrangement position of the core die 55 is deviated from the design position or the like, the core die 55 and the portion of the non-woven member 50 covering the core die 55 are covered with the trunk line by the pushing operation. Correction is made so as to be disposed at a predetermined design position in the circumferential direction of the portion 13.

  Thereafter, the upper mold surface 73 and the protrusion 74 of the upper mold 72 are inserted into the lower mold surface 63 and the recess 64, and in this state, the lower mold 62 and the upper mold 72 are heated to form a hot press mold 60. The non-woven member 50 is hot-pressed inside.

  Then, the non-woven member 50 is heated centering on a portion that contacts the lower mold 62 and the upper mold 72.

  Thereafter, when the non-woven member 50 is cooled, the non-woven member 50, in particular, the outer peripheral portion thereof is the lower die surface 63, the concave portion 64, the upper die surface 73, and the protrusion between the lower die 62 and the upper die 72. It hardens | cures in the shape according to the shape of 74, and, thereby, the connector fixing member 20 is formed.

  Thereafter, the wire harness main body 12 and the non-woven member 60 are taken out from the hot press mold 60. When the core die 55 is removed, a holding recess 28 corresponding to the outer shape of the core die 55 is formed in the connector holding portion 26.

  According to the wire harness 10 configured as described above, the holding recess 28 is formed in a shape that gradually narrows from the opening 28a toward the back side. Moreover, since the connector fixing member 20 is formed by hot pressing the non-woven member 50, it has a certain degree of elasticity. For this reason, when the connector part 16 is pushed into the holding recess 28, the connector part 16 is pressed against the main line portion 13 side by the inner side surface 28 c of the holding recess 28, and the connector part 16 is as easily and firmly as possible inside the holding recess 28. Can be fixed. Further, by pulling out the connector part 16 from the holding recess 28, the connector part 16 can be easily removed.

  In addition, since the holding recess 28 is formed in a shape that gradually narrows from the opening 28a toward the back side, even if the size of the connector holding portion 26 is slightly changed, it can be easily handled.

  Moreover, since the connector holding part 26 is integrally formed with the wire harness attachment part 22 by hot-pressing the non-woven member 50, the connector holding part 26 and the connector component 16 are not easily displaced from the main line part 13.

  The holding recess 28 is formed in a shape that gradually narrows from the opening 28a that is larger than the distal end portion of the connector component 16 toward the depth side until the size becomes smaller than the size that allows the connector component 16 to be pressed. The connector part 16 can be easily inserted into the recess 28, and the connector part 16 can be easily held by pressing the tip of the connector part 16 by pushing the connector part 16 into the holding recess 28. .

  Further, the depth dimension L1 of the holding recess 28 covers the entire connector component 16 in a state where the connector part 16 is inserted into the holding recess 28 and the tip thereof is pressed by the inner peripheral surface of the holding recess 28. Thus, the connector part 16 can be more reliably protected from being in contact with the external part. As a result, more reliable protection of the connector holding portion 26 and suppression of hitting sound due to contact between the connector component 16 and peripheral components can be achieved.

  Further, since the holding recess 28 has a slope-shaped inner side surface 28c that gradually narrows the internal space from the opening 28a side to the back side, the rectangular parallelepiped connector component 16 is pushed into the holding recess 28. Since the inner side surface 28c of the connector part 16 is brought into contact with the straight edge of the connector part 16 and the connector part 16 is pressed down, the connector part 16 can be pressed and held in a stable state.

  Further, since the holding recess 28 is opened on one side along the longitudinal direction of the main line portion 13, the connector part 16 is inserted into the holding recess 28 with the branch line portion 14 being along the main line portion 13. Can be held. For this reason, even if the length of the branch line portion 14 is short, the connector component 16 can be easily inserted into the holding recess 28. Further, since the branch line portion 14 can be disposed along the main line portion 13 with the connector part 16 inserted into the holding recess 28, the amount of protrusion of the branch line portion 14 from the wire harness 10 can be reduced. Interference between the portion 14 and the peripheral parts of the vehicle can be suppressed.

  However, it is not essential that the opening of the holding recess 28 is in the above-described direction, and the opening of the holding recess 28 is directed to one side along the circumferential direction of the main line portion 13 or to the outer side of the main line portion 13. It may be formed as follows.

  Further, since the main line portion 13 is exposed in the holding concave portion 28, the holding concave portion 28 is provided in the immediate vicinity of the main line portion 13. For this reason, the length of the branch line portion 14 can be further shortened.

  Moreover, the wire harness 10 can be easily manufactured by using the core die 55 as described above.

  In particular, by using the core die 55 and pushing the portion of the core die 55 and the non-woven member 50 covering the core die 55 into the recess 64 of the hot press mold 60, a connector for the main line portion 13 is obtained. There is an advantage that the formation positions of the holding portions 26 are easily aligned.

  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.
