Description

The present invention relates to a method for manufacturing a cable harness and a cable harness.

Patent document 1 discloses a flat circuit body in which multiple covered electric wires (wiring) are arranged in a flat shape.

As shown in Fig. 11, in the flat circuit body 90 of Patent Document 1, a plurality of covered electric wires 92 are arranged on one plane. The plurality of covered electric wires 92 form two groups. The covered electric wires 92 in one group extend straight in the longitudinal direction D _L. The covered electric wires 92 in the remaining group are bent so as to have a portion extending in the longitudinal direction D _L and a portion extending in a direction intersecting therewith. In other words, the covered electric wires 92 in the remaining group have a bent portion 94. The bent portion 94 is covered with a shape retaining portion 96.

Japanese Patent Application Publication No. 9-115341

In cable harnesses that include a cable and a connector attached to the end of the cable, there is a demand for the connector mating direction and the cable pull-out direction to cross each other. One method of meeting this demand is to adopt the technology disclosed in Patent Document 1.

However, as can be seen from FIG. 11, in the technology disclosed in Patent Document 1, the path length of the coated electric wire 92 located inside the bent portion 94 is different from the path length of the coated electric wire 92 located outside the bent portion. Therefore, when these coated electric wires 92 are used for high-speed signal transmission, skew occurs. Therefore, the technology disclosed in Patent Document 1 has the problem that it is not suitable for high-speed signal transmission.

To solve the above problem, the path lengths of the multiple wirings can be made equal. However, in that case, the multiple wirings will have to overlap each other at the bends. This means that the size of the bends will be larger in the vertical direction perpendicular to the bending direction of the wirings. When multiple wirings are used for high-speed signal transmission, they may be surrounded by a shell to prevent noise. In that case, if the bends are large, the wirings and the shell may come into contact with each other, which may damage the wiring.

The present invention aims to provide a cable harness that is suitable for transmitting high-speed signals and can prevent contact between the wiring and the shell.

The present invention relates to a method for manufacturing a cable harness including a cable having a plurality of wirings, the method comprising the steps of:
forming a bent portion by bending the wiring between the first position and the second position such that a direction in which the wiring extends at the first position and a direction in which the wiring extends at the second position intersect with each other;
The present invention provides a method for manufacturing a cable harness, in which the bent portion is sandwiched between an upper mold having a downward protrusion and a lower mold having an upward protrusion, and a molded portion that at least partially covers the bent portion is molded.

The present invention also provides a cable harness including a cable having a plurality of wirings as a first cable harness,
The wire is bent between a first position and a second position;
the wiring extends in a first direction at the first position,
the wiring extends in a second direction intersecting the first direction at the second position,
the wiring is at least partially embedded in a molded portion between the first position and the second position;
the mold portion has an upper surface and a lower surface in a vertical direction perpendicular to both the first direction and the second direction,
At least one upper groove recessed downward is formed on the upper surface,
At least one lower groove recessed upward is formed on the lower surface,
The wiring provides a cable harness in which the wiring is at least partially located between the at least one upper groove and the at least one lower groove in the vertical direction.

The present invention also provides a second cable harness comprising a first cable harness,
the at least one upper groove extends from one end of the mold portion to the other end of the mold portion in a horizontal plane defined by the first direction and the second direction;
The at least one lower groove provides a cable harness that extends across the molded section in the horizontal plane.

Furthermore, the present invention provides a third cable harness, which is the first or second cable harness,
the at least one upper groove includes a groove extending in a first orthogonal direction perpendicular to the first direction, a groove extending in a second orthogonal direction perpendicular to the second direction, and a groove extending in a cross direction intersecting both the first orthogonal direction and the second orthogonal direction,
The at least one lower groove may include a groove extending in the first orthogonal direction, a groove extending in the second orthogonal direction, and a groove extending in the intersecting direction.

Furthermore, the present invention provides a fourth cable harness, which is any one of the first to third cable harnesses,
The cable harness includes an equal length wiring structure between the first location and the second location.

Furthermore, the present invention provides a fifth cable harness, which is any one of the first to fourth cable harnesses,
The cable harness further comprises a shell,
The shell provides a cable harness at least partially covering the molded section.

Further, the present invention provides a sixth cable harness, which is the fifth cable harness,
The shell has an upper portion and a lower portion,
The upper portion has an upper abutment portion and a shell upper plate portion,
The lower portion has a lower abutment portion and a shell lower plate portion,
the upper abutment portion and the lower abutment portion face each other in the up-down direction, and a distance between the shell upper plate portion and the shell lower plate portion is restricted so as not to be equal to or smaller than a first size,
The molded portion provides a cable harness having a second size smaller than the first size in the vertical direction.

In the manufacturing method of the cable harness of the present invention, the bent portion of the wiring is at least partially covered by the molded portion while being sandwiched between an upper mold having a downward protrusion and a lower mold having an upward protrusion. As a result, in the vertical direction, the bent portion of the wiring is positioned away from the upper and lower surfaces of the molded portion. In this way, it is possible to provide a cable harness that realizes an equal-length wiring structure suitable for high-speed signal transmission and prevents contact between the bent portion of the wiring and the shell covering the molded portion.

In the cable harness of the present invention, the wiring is bent between a first position and a second position and is at least partially embedded in the molded section. An upper groove and a lower groove are formed on the upper and lower surfaces of the molded section, respectively. Between the first and second positions, the wiring is at least partially located between the upper and lower grooves and is spaced apart from the upper and lower surfaces of the molded section. This makes it possible to prevent contact between the wiring and the shell covering the molded section between the first and second positions when the wiring is bent between the first and second positions.

Referring to FIG. 1, an intermediate product 10A of a cable harness 10 (see FIG. 10) according to one embodiment of the present invention includes a cable 20, a molded section 30, a locator 40, a relay board 50, and a mating section 60. The molded section 30, the locator 40, the relay board 50, and the mating section 60 form a connector. However, the present invention is not limited to this. The cable harness 10 of the present invention only needs to include a cable 20 and a molded section 30.

As can be seen from FIG. 1, the mating portion 60 can be mated with and separated from a mating connector (not shown) in the front-to-rear direction. The mating portion 60 is attached to the front of the relay board 50. In this embodiment, the front-to-rear direction is the Y direction. The -Y direction is the front, and the +Y direction is the rear.

As shown in FIG. 1, the relay board 50 has a pair of main surfaces 52 that are perpendicular to the up-down direction. Each of the main surfaces 52 has a generally rectangular shape that is long in the front-to-rear direction. A plurality of connection pads 54 are formed on the surface of each of the main surfaces 52. In this embodiment, the up-down direction is the Z direction. The +Z direction is upward, and the -Z direction is downward.

As shown in FIG. 1, the locator 40 is located behind the relay board 50. As shown in FIG. 2, the cable 20 has a number of wires 22. As shown in FIGS. 3 and 4, the locator 40 holds the ends of the wires 22. The wires 22 are each connected to a connection pad 54 on the relay board 50.

As shown in FIG. 1, the molded section 30 is located behind the locator 40 in the front-to-rear direction. The molded section 30 has a generally rectangular parallelepiped shape that is small in size in the up-down direction. As can be seen from FIG. 1, the molded section 30 partially covers the wiring 22 of the cable 20.

As can be seen from FIG. 1, the wiring 22 is bent within the molded section 30. More specifically, the wiring 22 is bent so that the direction in which the wiring 22 extends at the first position P1 and the direction in which the wiring 22 extends at the second position P2 intersect with each other. Thus, the wiring 22 forms a bent section 224 (see FIGS. 5 and 6) between the first position P1 and the second position P2.

As shown in FIG. 1, in this embodiment, the first position P1 corresponds to the position of the front end surface of the molded section 30 in the front-rear direction. The second position P2 corresponds to the position of one side end surface of the molded section 30 in the lateral direction. In this embodiment, the lateral direction is the X direction.

As can be seen from FIG. 1, at the first position P1, the wiring 22 extends in a first direction perpendicular to the vertical direction. At the second position P2, the wiring 22 extends in a second direction perpendicular to the vertical direction and intersects with the first direction. In this embodiment, the first direction is the forward direction (-Y direction). Also, the second direction is the side direction (+X direction). Thus, in this embodiment, the first direction and the second direction are perpendicular to each other. However, the present invention is not limited to this. The first direction and the second direction do not have to be perpendicular to each other.

As can be seen from FIG. 1, the molded portion 30 at least partially covers the bent portion 224 (see FIGS. 5 and 6) of the wiring 22 between the first position P1 and the second position P2. In other words, the bent portion 224 of the wiring 22 is at least partially embedded in the molded portion 30 between the first position P1 and the second position P2.

As can be seen from FIG. 1, the molded part 30 has an upper surface 32 and a lower surface 34 (see FIG. 9) in the vertical direction. An upper groove 320 that is recessed downward is formed in the upper surface 32. Also, a lower groove 340 (see FIG. 9) that is recessed upward is formed in the lower surface 34. When viewed in the vertical direction, the upper groove 320 and the lower groove 340 are formed to coincide with each other. However, the present invention is not limited to this. The upper groove 320 and the lower groove 340 may be formed to partially overlap.

As shown in FIG. 1, in this embodiment, the upper groove 320 is composed of a first straight groove 322, a second straight groove 324, and a third straight groove 326. Each of the first straight groove 322, the second straight groove 324, and the third straight groove 326 is formed so as to intersect with the wiring 22 when viewed in the up-down direction. The lower groove 340 (see FIG. 9) is formed in the same manner as the upper groove 320. The following description of the upper groove 320 also applies mutatis mutandis to the description of the lower groove 340.

1, the first linear groove 322 is formed to intersect with the first direction. In a horizontal plane defined by the first and second directions, the first linear groove 322 extends from one end of the upper surface 32 of the molded section 30 to the other end. The first linear groove 322 is located closer to the first position P1 than the center of the molded section 30 in the front-rear direction. As a result, when viewed along a direction perpendicular to the horizontal plane, the first linear groove 322 necessarily intersects with all the wirings 22. In other words, when viewed along a direction perpendicular to the horizontal plane, all the wirings 22 necessarily intersect with the first linear groove 322. In this embodiment, the horizontal plane is a plane (XY plane) perpendicular to the up-down direction.

As shown in FIG. 1, the second linear groove 324 is formed so as to intersect with the second direction. The second linear groove 324 extends from one end of the upper surface 32 of the molded section 30 to the other end in the horizontal plane. The second linear groove 324 is located closer to the second position P2 than the center of the molded section 30 in the lateral direction. As a result, when viewed along a direction perpendicular to the horizontal plane, the second linear groove 324 necessarily intersects with all of the wiring 22. In other words, when viewed along a direction perpendicular to the horizontal plane, all of the wiring 22 necessarily intersect with the second linear groove 324.

As shown in FIG. 1, the third linear groove 326 extends in a cross direction that crosses both the first linear groove 322 and the second linear groove 324 in the horizontal plane. The third linear groove 326 extends from the center of the molded section 30 in a direction away from both the first position P1 and the second position P2. As a result, when viewed along a direction perpendicular to the horizontal plane, the third linear groove 326 crosses some or all of the wiring 22, including the wiring 22 located on the outermost side in the bent section 224.

As shown in FIG. 1, in this embodiment, the first linear groove 322, the second linear groove 324, and the third linear groove 326 are mutually connected. However, the present invention is not limited thereto. The first linear groove 322, the second linear groove 324, and the third linear groove 326 may not be mutually connected. In addition, the upper groove 320 may be composed of at least one linear groove or curved groove. In other words, it is sufficient that at least one upper groove 320 recessed downward is formed on the upper surface 32 of the molded part 30. Similarly, it is sufficient that at least one lower groove 340 (see FIG. 9) recessed upward is formed on the lower surface 34 of the molded part 30 (see FIG. 9). When each of the upper groove 320 and the lower groove 340 is composed of a single linear groove, the upper groove 320 and the lower groove 340 may extend in the same direction as each other, or may extend in directions intersecting each other. Furthermore, the straight or curved grooves constituting each of the upper groove 320 and the lower groove 340 may not reach the ends of the upper surface 32 or the lower surface 34 of the molded part 30 in the horizontal plane. On the other hand, for manufacturing reasons described later, each of the upper groove 320 and the lower groove 340 preferably has at least one groove that reaches from end to end of the upper surface 32 or the lower surface 34 of the molded part 30 in the horizontal plane.

As can be seen from FIG. 1, the bent portion 224 of the wiring 22 (see FIGS. 5 and 6) is at least partially located between the upper groove 320 and the lower groove 340 (see FIG. 9) in the vertical direction. Therefore, the wiring 22 may be partially exposed at the bottom of the upper groove 320. The wiring 22 may also be partially exposed at the bottom of the lower groove 340. However, the wiring 22 does not protrude into the upper groove 320 or the lower groove 340.

As described above, in this embodiment, the bent portion 224 of the wiring 22 (see Figures 5 and 6) is located between the bottom of the upper groove 320 and the bottom of the lower groove 340 in the vertical direction. Therefore, when the molded portion 30 is later covered with the shell 80, the wiring 22 and the shell 80 will not come into contact with each other. In this way, damage to the wiring 22 due to contact with the shell 80 is prevented.

Below, a method for manufacturing a cable harness 10 according to one embodiment of the present invention will be described with reference to Figures 1 to 10.

First, prepare the cable 20. Then, as shown in FIG. 2, remove the cable jacket 202 from the end of the prepared cable 20. This exposes the ends of the multiple wires 22 included in the cable 20.

Next, as shown in FIG. 3, a plurality of wirings 22 are combined with a locator 40. As a result, the ends of the wirings 22 are arranged and held by the locator 40. Also, at each end of the wirings 22, the core wire 220 is exposed, or the core wire 220 and the outer conductor 222 are exposed. At this time, the lengths of the wirings 22 are made as equal as possible. In particular, for wirings 22 used for high-speed signal transmission, the lengths are made practically equal. As a result, in the cable harness 10 of this embodiment, an equal-length wiring structure is realized between the first position P1 and the second position P2.

Next, as shown in FIG. 4, the locator 40 and the relay board 50 are combined. The relay board 50 has a mating portion 60 attached. The wires 22 are connected to the corresponding connection pads 54 of the relay board 50. Furthermore, the wires 22 are fixed to the relay board 50 by UV potting. This is to reduce the load on the connection between the wires 22 and the connection pads 54 when the wires 22 are bent later. The locator 40 and the relay board 50 may or may not be fixed to each other.

Next, as shown in Figures 5 and 6, the wiring 22 is sandwiched between an upper mold 70 and a lower mold 72. The upper mold 70 and the lower mold 72 are used to mold the molded part 30 (see Figure 1). The upper mold 70 has a downward protrusion 702 in the vertical direction. The protrusion 702 of the upper mold 70 corresponds to the upper groove 320 of the molded part 30 (see Figure 1). For example, the part of the protrusion 702 corresponding to the first linear groove 322 has a rectangular cross section, protrudes into the cavity 704 of the upper mold 70, and extends linearly from one end of the cavity 704 to the other end. The lower mold 72 has an upward protrusion 722 in the vertical direction. The protrusion 722 of the lower mold 72 corresponds to the lower groove 340 of the molded part 30 (see Figure 9). For example, the portion of the protrusion 722 corresponding to the first linear groove 342 has a rectangular cross section, protrudes into the cavity 724 of the lower mold 72, and extends linearly from one end of the cavity 724 to the other end. When viewed in the vertical direction, the protrusion 702 of the upper mold 70 and the protrusion 722 of the lower mold 72 may coincide with each other or may partially overlap. However, it is preferable that the protrusion 702 of the upper mold 70 and the protrusion 722 of the lower mold 72 coincide with each other, since this makes it possible to more reliably hold the wiring 22. In addition, it is preferable that each of the protrusions 702 of the upper mold 70 and the protrusions 722 of the lower mold 72 has a portion that forms at least one groove that extends from one end of the upper surface 32 or the lower surface 34 of the molded part 30 in a horizontal plane. This is to more reliably hold the wiring 22.

As can be seen from FIG. 1, the wiring 22 is bent prior to the formation of the molded portion 30. In detail, the wiring 22 is bent between the first position P1 and the second position P2 so that the extension direction of the wiring 22 at the first position P1 and the extension direction of the wiring 22 at the second position P2 intersect with each other to form a bent portion 224 (see FIGS. 5 and 6). At this time, the line lengths of the wiring 22 are made equal between the first position P1 and the second position P2. In other words, the wiring 22 is bent to realize an equal-length wiring structure between the first position P1 and the second position P2.

As shown in Figures 5 and 6, after forming the bent portion 224, the upper die 70 and the lower die 72 are brought closer to each other in the vertical direction so as to sandwich the bent portion 224. At this time, the bent portion 224 may be bulging in the vertical direction. The protrusions 702 of the upper die 70 and the protrusions 722 of the lower die 72 suppress the bulging of the wiring 22. Then, while sandwiching the bent portion 224 between the upper die 70 and the lower die 72, the molded portion 30 is molded to at least partially cover the bent portion 224. In this way, the intermediate product 10A of the cable harness 10 is completed.

As can be seen from FIG. 6, the molded section 30 (see FIG. 1) is formed in a state in which the bent portion 224 of the wiring 22 is sandwiched between the protrusions 702 and 722. Therefore, in the vertical direction, the uppermost position of the bent portion 224 of the wiring 22 is equal to the bottom position of the upper groove 320 (see FIG. 1). Also, in the vertical direction, the lowermost position of the bent portion 224 of the wiring 22 is equal to the bottom position of the lower groove 340 (see FIG. 9). Therefore, the bent portion 224 of the wiring 22 is separated from both the upper surface 32 (see FIG. 1) and the lower surface 34 (see FIG. 9) of the molded section 30.

Next, as shown in Figures 7 and 8, the shell 80 is attached to the intermediate product 10A. The shell 80 at least partially covers the molded section 30. In this embodiment, the shell 80 covers substantially the entire molded section 30. The shell 80 also covers the rear end of the mating section 60 and the relay board 50.

As can be seen from Figures 7 to 9, the shell 80 has an upper portion 82 and a lower portion 84.

7 to 9, the upper portion 82 has a shell upper plate portion 820, side plate portions 822 and 824, a rear plate portion 826, and a retaining portion 828. The shell upper plate portion 820 is a substantially rectangular flat plate perpendicular to the up-down direction. The side plate portions 822 and 824 extend downward from both edges of the shell upper plate portion 820 in the lateral direction. The rear plate portion 826 extends downward from the rear edge of the shell upper plate portion 820. At least one cut-and-raised portion 830 is formed on each of the side plate portions 822 and 824 and the rear plate portion 826. In this embodiment, two cut-and-raised portions 830 are formed on the side plate portion 822. Also, three cut-and-raised portions 830 are formed on the side plate portion 824. Also, in this embodiment, one cut-and-raised portion 830 is formed on the rear plate portion 826. The cut-and-raised portion 830 extends diagonally upward and outward, and then continues upward.

7 to 9, the lower portion 84 has a shell lower plate portion 840, side plate portions 842 and 844, and a rear plate portion 846. The shell lower plate portion 840 is a substantially rectangular flat plate perpendicular to the up-down direction. The side plate portions 842 and 844 extend upward from both edges of the shell lower plate portion 840 in the lateral direction. The rear plate portion 846 extends upward from the rear edge of the shell lower plate portion 840. At least one opening 850 is formed in each of the side plate portions 842 and 844 and the rear plate portion 846. The openings 850 correspond to the cut-and-raised portions 830 of the upper portion 82. In this embodiment, two openings 850 are formed in the side plate portion 842. Three openings 850 (not shown) are formed in the side plate portion 844. In this embodiment, the rear plate portion 846 has one opening 850 formed therein.

7 and 9, when the upper portion 82 and the lower portion 84 are combined, the upper portion 82 is located inside the lower portion 84 in the horizontal plane. The cut-and-raised portion 830 of the upper portion 82 is elastically deformable. The upper portion 82 enters the lower portion 84 due to the elastic deformation of the cut-and-raised portion 830. The restoring force of the cut-and-raised portion 830 causes each of the cut-and-raised portions 830 to be at least partially received in the corresponding opening 850. This causes the tip edge of each of the cut-and-raised portions 830 and the upper edge of the corresponding opening 850 to face each other in the vertical direction. As a result, the upper portion 82 and the lower portion 84 are prevented from being separated from each other.

As shown in FIG. 9, a cut-and-raised portion 852 is formed on the rear plate portion 846 of the lower portion 84. The cut-and-raised portion 852 extends diagonally upward inward and further upward. When the upper portion 82 and the lower portion 84 are combined, the tip edge 854 of the cut-and-raised portion 852 of the lower portion 84 faces the lower edge 832 of the rear plate portion 826 of the upper portion 82 in the vertical direction. Here, the tip edge 854 of the cut-and-raised portion 852 and the lower edge 832 of the rear plate portion 826 of the upper portion 82 are set so that when they butt against each other, the distance size between the shell upper plate portion 820 and the shell lower plate portion 840 in the vertical direction is equal to or larger than a first size. In other words, the leading edge 854 of the cut-and-raised portion 852 and the lower edge 832 of the rear plate portion 826 regulate the distance between the shell upper plate portion 820 and the shell lower plate portion 840 in the vertical direction so as not to be equal to or smaller than the first size. In this manner, the lower edge 832 of the rear plate portion 826 of the upper portion 82 and the leading edge 854 of the cut-and-raised portion 852 of the rear plate portion 846 of the lower portion 84 function as the upper abutment portion 832 and the lower abutment portion 854, respectively, which regulate the distance between the shell upper plate portion 820 and the shell lower plate portion 840. Here, by setting the size of the molded portion 30 in the vertical direction to a second size smaller than the first size, contact between the molded portion 30 and both the shell upper plate portion 820 and the shell lower plate portion 840 can be suppressed. As a result, even if an external force is applied to the shell 80, the external force can be prevented from being directly applied from the shell 80 to the molded portion 30. Even if the molded part 30 comes into contact with either the shell upper plate part 820 or the shell lower plate part 840, the molded part 30 prevents the wiring 22 from coming into contact with the shell upper plate part 820 or the shell lower plate part 840.

Next, as shown in Figures 7 and 8, the upper portion 82 and the lower portion 84 are assembled, and then the holding portion 828 is bent to hold the cable 20.

Finally, as shown in FIG. 10, the outer mold part 88 is molded to cover the shell 80. Then, if necessary, a hood is attached to cover the outer mold part 88. In this way, the cable harness 10 is completed.

As described above, the cable harness 10 of this embodiment is configured so that the wiring 22 and the shell 80 do not come into contact with each other. Furthermore, the cable harness 10 of this embodiment has an equal-length wiring structure at the bent portion 224. Therefore, the cable harness 10 of this embodiment is suitable for transmitting high-speed signals, and the wiring 22 will not come into contact with the shell 80 and be damaged.

Although the present invention has been described above with reference to an embodiment, the present invention is not limited to the above embodiment, and various modifications and changes are possible without departing from the spirit of the present invention. For example, the shape of the mating portion 60 is not limited to that shown in the drawings, and any shape is possible. For example, the relay board 50 may be eliminated, and the wiring 22 may be directly connected to the mating portion 60. Furthermore, the number of wirings 22 is not particularly limited, and may be two or more.
