Description

  The present invention relates to a wire harness having a water stop structure at a connection portion between an insulated wire and a terminal fitting.

  In a vehicle such as an automobile, a wire harness includes an electric wire with a terminal having an insulated wire that conducts electricity and a terminal fitting connected to an end of the insulated wire. The terminal fitting is generally a metal member mainly composed of copper.

  In an electric wire with a terminal mounted on a vehicle, a core wire exposed from an insulating coating portion of an insulated wire is connected to a core wire connecting portion which is a part of a terminal fitting by welding such as crimping or ultrasonic welding.

  By the way, in the electric wire with terminal, when liquid enters the connecting portion between the core wire of the insulated wire and the terminal fitting, the connecting portion is corroded. In particular, when the core wire of the insulated wire is an aluminum wire, corrosion due to dissimilar metal contact corrosion occurs.

  Then, in order to prevent the corrosion of the connection part of the core wire of an insulated wire and a terminal metal fitting, the wire harness provided with the mold part as shown, for example in patent document 1 and patent document 2 is proposed. The mold part also serves to prevent liquid from entering the device by closing the gap between the insulated wire and the housing at the opening of the housing that houses the device to which the insulated wire is connected. The mold part is a synthetic resin member obtained by injection molding.

  The wire harness shown by patent document 1 is equipped with the mold part which sealed the water stop area | region ranging from the connection part of the core wire of an insulated wire and a terminal metal fitting in a terminal-attached electric wire to a part of edge part of an insulated wire. In this case, the connection portion between the insulated wire and the terminal fitting is water-stopped by the mold portion, and corrosion is prevented.

  The mold part of the wire harness as shown in Patent Document 1 is made by insert molding using a mold for molding the mold part and an injection device for injecting molten synthetic resin into the mold.

  The mold is generally composed of an upper mold and a lower mold. The upper mold and the lower mold are supported so that one or both of them can approach and be separated while facing each other. In the mold mold in which the upper mold and the lower mold are closest to each other, the first accommodation space in which the part other than the water stop area in the terminal fitting is accommodated, and the water stop area part of the electric wire with terminal are accommodated. And a third accommodation space in which a portion other than the water stop region at the end of the insulated wire is accommodated in that order.

  The injection device is a device for injecting molten synthetic resin into the second housing space of the mold. The molded part of the wire harness is formed by solidification of the synthetic resin injected into the second housing space in a state where the water stop region of the terminal-equipped electric wire is housed in the second housing space of the mold. Is done.

  Hereinafter, in the mold part of the wire harness, a part formed at the boundary part with the third accommodation space in the second accommodation space of the mold is referred to as a rear end.

  On the other hand, the wire harness shown in Patent Document 2 includes a first mold portion that seals an area extending from a connection portion between a core wire of an insulated wire and a terminal fitting in a terminal-attached wire to a coated end portion of the insulated wire, and the insulated wire. A second mold part interposed between the covering end part and the end part of the first mold part; The second mold part is an elastomer member.

  By the way, when the conditions of the bending specification of an insulated wire are severe, it is necessary to employ an insulated wire having a softer and thinner insulation coating. For example, there are cases where it is necessary to bend an insulated wire with a particularly large curvature when attached to a vehicle, or when the frequency of bending deformation of the insulated wire is particularly high.

  On the other hand, when the insulation coating of the insulated wire is made of a material softer than a general coating material, when the mold part as described above is formed by insert molding, the inner edge of the rear end of the mold part is It tends to become a shape that bites into the insulation coating of insulated wires. When such an insulated wire with a mold part is used under conditions of strict bending specifications, the possibility that the biting part of the mold part damages the soft and thin insulation coating cannot be denied.

  The same applies to the inner edge portion of the rear end of the second mold portion in the wire harness disclosed in Patent Document 2.

  Moreover, in manufacture of the wire harness shown by patent document 2, it is necessary to mold twice about a 1st mold part and a 2nd mold part. In this case, after molding the second mold part, it takes time-consuming work such as once taking out the wire harness from the mold for molding the second mold part and transferring it to the mold for molding the first mold part. . Performing such a laborious work is contrary to the demand for cost reduction and lead time reduction.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example embodying the present invention, and is not an example of limiting the technical scope of the present invention. In the present specification, the term “wire harness” is used as a term for convenience, including a case where only one insulated wire is included and a case where a plurality of insulated wires are included. In addition, you may call the wire harness in this specification a wire with a mold part, or an electric wire module.

<First Embodiment>
First, the configuration of the wire harness 1 according to the first embodiment will be described with reference to FIGS. The wire harness 1 includes an insulated wire 9, a terminal fitting 8, a protective member 7, and a mold part 6. The wire harness 1 is mounted on a vehicle such as an automobile.

  FIG. 1 is a plan view of an end portion of the wire harness 1. FIG. 2 is a cross-sectional view of the wire harness 1 in the II-II plane of FIG. FIG. 3 is a perspective view showing the protective member 7 before being mounted at a regular position.

<Insulated wire>
As shown in FIGS. 1 and 2, the insulated wire 9 to which the terminal fitting 8 is attached includes a core wire 910 that is a long conductor, and an insulation coating 920 that is an insulator covering the periphery of the core wire 910, It is an electric wire which has. In general, the core wire 910 is a stranded wire in which a plurality of strands made of thin conductors are twisted together. However, it is also conceivable that the core wire 910 is a single wire.

  The end portion of the insulated wire 9 to which the terminal fitting 8 is attached is in a state in which the insulation coating 920 has been peeled from the periphery of the core wire 910 of a certain length in advance, that is, the core wire 910 of a certain length is removed from the insulation coating 920. Processed in an extended state.

  Hereinafter, the core wire 910 extending from the end of the insulation coating 920 at the end portion of the insulated wire 9 is referred to as a bare wire portion 91. In addition, a portion in a certain range (a range having a length of about several millimeters to several tens of millimeters) at the end of the insulating coating 920 of the insulated wire 9 is referred to as a covered end 92.

  In the wire harness 1, the core wire 910 of the insulated wire 9 is, for example, a metal wire whose main component is aluminum. On the other hand, the insulation coating 920 of the insulated wire 9 is a synthetic resin member mainly composed of, for example, polyethylene, vinyl chloride, or polyamide-based nylon. It is also conceivable that the core wire 910 is a metal wire mainly composed of copper.

<Terminal fitting>
As shown in FIGS. 1 and 2, the terminal fitting 8 has a contact portion 81 and a core wire connection portion 82.

  The contact part 81 is a part connectable with other members. In the present embodiment, for example, a connection hole 810 through which a screw for fixing a terminal fitting 8 such as a terminal fixing base to a connection partner is passed is formed in the contact portion 81.

  The core wire connection portion 82 is a portion to which the bare wire portion 91 extending from the covered end portion 92 of the insulated wire 9 is connected.

  In the present embodiment, the core wire connection portion 82 includes a bottom plate portion 821 and two core wire caulking portions 822. That is, this embodiment is an example of the case where the core wire connecting portion 82 is connected to the insulated wire 9 by crimping.

  The core wire connecting portion 82 is a plate-like portion formed by bending in a state before being crimped to the insulated wire 9, and forms a groove into which the bare wire portion 91 of the insulated wire 9 is inserted.

  The bottom plate portion 821 is a portion that supports the bare wire portion 91 in the insulated wire 9 to which the terminal fitting 8 is attached from one side. The bottom plate part 821 is connected to the contact part 81.

  The two core wire caulking portions 822 are portions formed so as to rise from the bottom plate portion 821 to both sides of the bare wire portion 91. In addition, the core wire connection part 82 in this embodiment is a butting type in which the two core wire crimping parts 822 do not overlap. However, it is also conceivable that the core wire connecting portion 82 is of an overlapping type in which two core wire caulking portions 822 are overlapped and caulked to the bare wire portion 91, or a closed barrel type formed in a cylindrical shape.

  In the wire harness 1, the insulated wire 9 is inserted inside a groove formed by the core wire connecting portion 82. Then, the upright two core wire caulking portions 822 are bent along the periphery of the bare wire portion 91, bent in a direction facing the bottom plate portion 821, and caulked to the bare wire portion 91. As a result, the core wire connecting portion 82 is crimped to the bare wire portion 91.

  The terminal fitting 8 is obtained by bending a metal plate material. Moreover, the metal plate material which comprises the terminal metal fitting 8 is obtained by the punching process with respect to the plate-shaped metal base material in which plating was formed. Accordingly, the metal plate constituting the terminal fitting 8 is constituted by a base material and plating formed on the surface of the base material.

  For example, the base material of the terminal fitting 8 is a member made of a metal material whose main component is copper, such as copper or a copper alloy. In this case, the entire terminal fitting 8 including plating is made of a metal material mainly composed of copper. On the other hand, the plating is a member made of a metal material mainly composed of tin, such as tin (Sn) or tin alloy in which silver (Ag), copper (Cu), bismuth (Bi) or the like is added to tin. Silver (Ag) plating or nickel (Ni) plating is also conceivable.

<Protective member>
The protective member 7 shown in FIGS. 1 to 3 is a member formed in a cylindrical shape by attaching a pre-formed member to the covered end portion 92 of the insulated wire 9. It adheres to the outer peripheral surface over its entire circumference.

  As shown in FIG. 3, the protective member 7 in this embodiment has a two-layer structure including a heat shrinkable tube 71 and a thermoplastic adhesive layer 72 formed on the inner surface of the heat shrinkable tube 71. Therefore, in the present embodiment, the protective member 7 is a member in which the heat shrinkable tube 71 through which the covering end portion 92 of the insulated wire 9 is passed is contracted, and the inner surface of the protective member 7 is the insulating coating 920 of the insulated wire 9. It is an example in the case of being bonded to the outer peripheral surface of the.

  The heat-shrinkable tube 71 is a cylindrical member made of synthetic resin such as polyolefin, nylon, silicon, fluororesin, or polyester elastomer. The heat-shrinkable tube 71 is obtained by cooling a resin member that has been formed into a very thin cylindrical shape by extrusion, after being stretched into a thick cylindrical shape in a heated state. The heat-shrinkable tube 71 thus obtained has a shape memory characteristic that, when heated, contracts to a thin cylindrical shape before being stretched.

  As the adhesive forming the adhesive layer 72, for example, a modified olefin-based or polyester-based hot melt adhesive may be considered.

<Mold part>
The mold part 6 shown in FIGS. 1 and 2 is from the portion between the contact part 81 and the core wire connecting part 82 of the terminal metal 8 in the insulated wire 9, the terminal metal 8 and the protective member 7 to the outer peripheral surface of the protective member 7. It is a part formed by insert molding in the range. In the present embodiment, the mold portion 6 is formed from the portion between the contact portion 81 of the terminal fitting 8 and the core wire connecting portion 82 of the insulated wire 9, the terminal fitting 8 and the protection member 7 to the middle portion of the protection member 7. Formed in the range.

  In the wire harness 1, the mold portion 6 is, for example, on the inner surface of the end portion on the contact portion 81 side of the terminal fitting 8 with respect to the outer surface of the portion between the contact portion 81 and the core wire connecting portion 82 in the terminal fitting 8. Close to the entire circumference.

  In the wire harness 1, the mold portion 6 is, for example, on the inner surface of the end portion (hereinafter referred to as the rear end portion 60) opposite to the contact portion 81 side of the terminal fitting 8 with respect to the outer peripheral surface of the protection member 7. Close to the entire circumference. Therefore, liquid can be prevented from entering the connecting portion between the bare wire portion 91 of the insulated wire 9 and the core wire connecting portion 82 of the terminal fitting 8.

  The mold part 6 is a synthetic resin member. The synthetic resin constituting the mold part 6 is, for example, a PPS (polyphenylene sulfide) resin, a PPA (polyphthalamide) resin, an LCP resin (liquid crystal polymer), a phenol-based, polyester-based, polyamide-based, or epoxy-based resin. .

  The molding process of the mold part 6 will be described later.

<Wire harness manufacturing process>

FIG. 6 is a cross-sectional view of the member 7.

<Manufacturing process of wire harness: mold>
First, the metal mold | die 5 used for manufacture of the wire harness 1 in this embodiment is demonstrated. The mold 5 is an example of a mold member used in manufacturing the wire harness 1. The mold 5 includes an upper mold 51 and a lower mold 52 as shown in FIG. The upper mold 51 and the lower mold 52 are supported by a support mechanism (not shown) so that one or both of them can approach and be separated from each other.

  Hereinafter, the insulated wire 9 in a state where the terminal fitting 8 is connected to the bare wire portion 91 and the protection member 7 is in close contact with the outer peripheral surface of the covering end portion 92 over the entire circumference, that is, the terminal fitting 8 and the protection member 7 are provided. The insulated wire 9 having the terminal is referred to as a terminal-attached wire 90.

  As shown in FIG. 4, in the mold 5 in a state where the upper mold 51 and the lower mold 52 are closest, the first accommodation space 501 in which the terminal-attached electric wire 90 is accommodated, the second accommodation space 502, and A third accommodation space 503 is formed.

  As shown in FIG. 4, the upper mold 51 is formed with a first molding part 511, a second molding part 512, and a third molding part 513. Similarly, the lower mold 52 is also formed with a first molding part 521, a second molding part 522, and a third molding part 523.

  In a state where the upper mold 51 and the lower mold 52 are closest, the space surrounded by the first molding part 511 in the upper mold 51 and the first molding part 521 in the lower mold 52 is a terminal of the electric wire 90 with terminal. A portion of the metal fitting 8 other than the area where the mold portion 6 is formed, that is, a portion from the portion between the contact portion 81 and the core wire connecting portion 82 of the terminal fitting 8 to the tip portion of the contact portion 81 is accommodated. One accommodation space 501 is formed.

  Further, in a state where the upper mold 51 and the lower mold 52 are closest to each other, a space surrounded by the second molded portion 512 in the upper mold 51 and the second molded portion 522 in the lower mold 52 is a wire 90 with a terminal. A second accommodation space 502 is formed in which a portion corresponding to a range from a portion between the contact portion 81 of the terminal fitting 8 and the core wire connection portion 82 to an intermediate portion of the protection member 7 is accommodated.

  Further, in a state where the upper mold 51 and the lower mold 52 are closest to each other, the space surrounded by the third molded portion 513 in the upper mold 51 and the third molded portion 523 in the lower mold 52 is the electric wire 90 with terminal. A part of the insulated wire 9 and a part of the protective member 7 of the terminal-attached electric wire 90 other than the area where the molded portion 6 is formed, that is, an intermediate part of the protective member 7 is opposite to the terminal fitting 8 side of the protective member 7. A third accommodation space 503 is formed in which a portion up to the end on the side is accommodated.

<Wire harness manufacturing process: protective member mounting process>
Next, with reference to FIG. 5, a mounting process for the covering end portion 92 of the insulated wire 9 of the protective member 7 in the wire harness 1 will be described.

  In this embodiment, the protective member 7 has a two-layer structure including a heat shrinkable tube 71 and a thermoplastic adhesive layer 72 formed on the inner surface of the heat shrinkable tube 71.

  As shown in FIG. 5, in the mounting process of the protective member 7 to the covered end portion 92 of the insulated wire 9 in this embodiment, the protective member 7 before contraction through which the covered end portion 92 of the insulated wire 9 is passed is a heater or the like. This is performed by being heated by the heater 125.

  The mounting process of the protective member 7 may be performed before the terminal fitting 8 is connected to the bare wire portion 91 of the insulated wire 9 or after the terminal fitting 8 is connected to the bare wire portion 91 of the insulated wire 9. It may be done. Therefore, in this embodiment, it becomes possible to give freedom to the order of the manufacturing process of the wire harness 1. In addition, if the terminal metal fitting 8 is connected to the bare wire part 91 of the insulated wire 9, the electric wire 90 with a terminal will be obtained by this attachment process.

  As shown in FIG. 5, the heat-shrinkable tube 71 after shrinkage is bonded to the outer peripheral surface of the insulating coating 920 of the insulated wire 9 by the adhesive layer 72 without gaps over the entire circumferential direction. Thereby, the protection member 7 adheres to the outer peripheral surface of the covering end portion 92 of the insulated wire 9 over the entire circumference.

<Wire harness manufacturing process: Mold part forming process>
Next, the molding process of the mold part 6 in the wire harness 1 will be described with reference to FIG.

  The molding process of the mold part 6 is performed after the mounting process of the protective member 7. In addition, when the attachment process of the protection member 7 was performed before the process of connecting the terminal metal fitting 8 to the bare wire part 91 of the insulated wire 9, the molding process of the mold part 6 and the attachment process of the protection member 7 are performed. In the meantime, the connection process (crimping process) of the terminal fitting 8 to the insulated wire 9 is performed.

  In the molding process of the mold part 6, for example, after the terminal-attached electric wire 90 is set in the lower mold 52, the upper mold 51 is brought close to the lower mold 52 in a state of facing the lower mold 52. Thereby, the electric wire 90 with a terminal is accommodated in the 1st accommodation space 501, the 2nd accommodation space 502, and the 3rd accommodation space 503 which the metal mold | die 5 forms.

  In the state where the terminal-attached electric wire 90 is accommodated in the first accommodation space 501, the second accommodation space 502, and the third accommodation space 503 of the mold 5, the synthetic resin melted by an unillustrated injection device is the second accommodation space. Injected into 502.

  When the synthetic resin injected into the second housing space 502 is solidified, the portion of the terminal-equipped electric wire 90 that is accommodated in the second housing space 502 of the mold 5, that is, the contact point of the terminal fitting 8 in the terminal-equipped electric wire 90. The mold part 6 is formed without a gap around the part corresponding to the range from the part between the part 81 and the core wire connecting part 82 to the middle part of the protective member 7.

  The protective member 7 prevents the synthetic resin melted at the boundary portion between the second housing space 502 and the third housing space 503 from forming into the insulating coating 920 side of the insulated wire 9 when the mold portion 6 is molded. That is, according to the present embodiment, the protective member 7 covering the insulating coating 920 can be harder than the insulating coating 920 when the mold portion 6 is molded. As such a combination of the insulating coating 920 and the protective member 7, for example, the material of the insulating coating 920 is a synthetic resin of crosslinked PE (polyester) and an elastomer, and the material of the heat shrinkable tube 71 of the protective member 7 is crosslinked PE. The case where it is (polyester) etc. can be considered.

<Effect>
In the present embodiment, insert molding of the mold part 6 is performed in a state where the protective member 7 is in close contact with the outer peripheral surface of the covered end portion 92 of the insulated wire 9 over the entire circumference. That is, the protective member is provided between the inner edge portion of the rear end portion 60 of the mold portion 6 and the insulating coating 920 of the insulated wire 9 formed at the boundary portion between the second housing space 502 of the mold 5 and the third housing space 503. Insert molding of the mold part 6 is performed in a state where 7 is interposed. In this case, the degree to which the inner edge portion of the rear end portion 60 of the mold portion 6 bites into the insulating coating 920 of the insulated wire 9 is alleviated. That is, a portion that bites into the insulating coating 920 is not easily formed in the mold portion 6.

  As shown in FIG. 15, the two unit molded portions 70 </ b> X are approached from a state in which the connecting portions 75 of the two unit molded portions 70 </ b> X are opposed to each other with the insulated wire 9 interposed therebetween. Eventually, the projections 751 of each of the two unit molding portions 70X are fitted into the fitting hole portions 752 of the counterpart unit molding portion 70X, thereby connecting the two unit molding portions 70X. As a result, the two unit molded portions 70 </ b> X are attached to the covered end portion 92 of the insulated wire 9. The two unit molded portions 70X attached to the covered end portion 92 of the insulated wire 9 constitute a protective member 7X that is in close contact with the outer peripheral surface of the covered end portion 92 of the insulated wire 9 over the entire circumference.

  Similar to the mounting process of the protective member 7, the mounting process of the protective member 7 </ b> X may be performed before the terminal fitting 8 is connected to the bare wire portion 91 of the insulated wire 9, or the insulated wire 9 may be bare. It may be performed after the terminal fitting 8 is connected to the wire portion 91.

<Wire harness manufacturing process: Mold part forming process>
Next, the molding process of the mold part 6 in the wire harness 1X will be described with reference to FIG.

  The molding process of the mold part 6 is performed after the mounting process of the protective member 7X. In addition, when the attachment process of the protection member 7X was performed before the process of connecting the terminal metal fitting 8 to the bare wire part 91 of the insulated wire 9, the molding process of the mold part 6 and the attachment process of the protection member 7X are performed. In the meantime, the connection process (crimping process) of the terminal fitting 8 to the insulated wire 9 is performed.

  In a state where the terminal-attached electric wire 90 is accommodated in the first accommodation space 501, the second accommodation space 502, and the third accommodation space 503 of the mold 5, the synthetic resin melted by an unillustrated injection device is contained in the second accommodation space 502. Is injected into. At this time, if the distal end portion 171 of the protective member 7X is gradually formed thinner toward the terminal fitting 8 side, the circulation of the synthetic resin near the distal end portion 171 of the protective member 7X is improved.

The mold part 6 is formed without a gap around the part corresponding to the range from the part between the part 81 and the core wire connecting part 82 to the intermediate part of the protective member 7X.

  The protective member 7 </ b> X prevents the synthetic resin melted at the boundary between the second housing space 502 and the third housing space 503 during the molding of the mold portion 6 from biting into the insulating coating 920 side of the insulated wire 9. That is, according to the present embodiment, the protective member 7X that covers the insulating coating 920 can be made harder than the insulating coating 920 when the mold portion 6 is molded.
