  FIG. 1 is a perspective view showing an appearance of a wire harness 100 to which a wire harness 100 with a branch member, that is, a wire harness branch member 1 (hereinafter simply referred to as “branch member 1”) is attached. The wire harness 100 includes a plurality of electric wires 200a to 200d and is arranged in a vehicle such as an automobile. In the wire harness 100, for example, the trunk line 110 is branched into three branch lines 111 a to 111 c by the branch member 1. The branch line 111a is constituted by an electric wire 200a, the branch line 111b is constituted by electric wires 200b and 200c, and the branch line 111c is constituted by an electric wire 200d. Hereinafter, when it is not necessary to distinguish between the electric wires 200a to 200d, each of them is referred to as an “electric wire 200”.

  Terminals are attached to both ends of the electric wires 200a to 200d. A terminal attached to one end of the electric wires 200a to 200d is inserted into the connector 60a, whereby the connector 60a is attached to one end of the electric wires 200a to 200d. Further, the terminal attached to the other end of the electric wire 200a is inserted into the connector 60b, whereby the connector 60b is attached to the other end of the electric wire 200a (the end of the branch line 111a). Further, the terminals attached to the other ends of the electric wires 200b and 200c are inserted into the connector 60c, whereby the connector 60c is attached to the other end of the electric wires 200b and 200c (the end of the branch line 111b). And the terminal attached to the other end of the electric wire 200d is inserted into the connector 60d, whereby the connector 60d is attached to the other end of the electric wire 200d (the end of the branch line 111c).

  The branch member 1 is a member for branching the wire harness 100, and is formed of, for example, resin.

The electric wire 200d is an electric wire that transmits a signal that is relatively easily affected by noise from the surroundings, and is a signal electric wire that transmits an audio signal, for example. The branch member 1 branches the wire harness 100 while separating the electric wire 200a and the electric wire 200d.

  On the other hand, each of the electric wires 200b and 200c is an electric wire that transmits a signal that is relatively less likely to generate noise and that is relatively less susceptible to noise from the surroundings. Therefore, each of the electric wires 200b and 200c is an electric wire that does not need to be separated from the other electric wires 200.

  FIG. 2 is a perspective view showing the branching member 1 and the lid member 50 apart. As shown in FIG. 2, the branch member 1 includes a bottom portion 10, an outer wall portion 11 erected on the peripheral edge of the upper surface of the bottom portion 10, and a locking structure erected at the center portion of the upper surface of the bottom portion 10. 13. The bottom part 10, the outer wall part 11, and the locking structure 13 are integrally formed.

An electric wire 200 of the wire harness 100 is passed through each notch 12. The locking structure 13 is configured to lock in the mounting hole of the mounting object to which the branch member 1 is mounted. The notch portion 12 may be formed at the same time when the bottom portion 10, the outer wall portion 11, and the locking structure 13 are produced using a mold, or the bottom portion 10, the outer wall portion 11, the locking structure 13, and the like. The outer wall portion 11 may be processed and formed after manufacturing. Hereinafter, simply speaking “attachment object” means an attachment object to which the branch member 1 is attached.

  The lid member 50 includes a main body 51 that covers the opening 15 on the upper surface of the branch member 1 and a plurality of locking portions 52 that extend downward from the periphery of the main body 51. The main body 51 and the plurality of locking portions 51 are integrally formed. The main body 51 is provided with a through hole 51a.

  When the lid member 50 is attached to the branch member 1, the locking structure 13 of the branch member 1 is inserted from the locking portion 52 side into the through hole 51 a of the main body portion 51 of the lid member 50. Then, when the locking structure 13 of the branch member 1 is inserted into the through hole 51a of the lid member 50 until the upper end surface of the outer wall portion 11 of the branch member 1 hits the lower surface (back surface) of the main body 51 of the lid member 50, The locking pieces 52 a at the tips of the plurality of locking portions 52 of the lid member 50 are locked to the lower surface (back surface) of the bottom portion 10 of the branch member 1. Thereby, the lid member 50 is attached to the branch member 1.

  Next, the structure of the branch member 1 will be described in more detail. 3 to 6 are a perspective view, a top view, a side view, and a bottom view showing the branch member 1, respectively.

  3-6, the bottom part 10 is a circular plate-shaped part, for example, Comprising: The through-hole 10a is provided in the center part. The outer wall portion 11 rises from the peripheral edge of the upper surface of the bottom portion 10 so as to surround the through hole 10a of the bottom portion 10 in a circular shape. The bottom part 10 and the outer wall part 11 have a cylindrical shape with an open upper surface as a whole. Therefore, as shown in FIG. 4, the outer shape of the branch member 1 in a top view is circular.

  In the present embodiment, for example, four notch portions 12 are provided in the outer wall portion 11. Each notch 12 is a groove-like notch that extends from the upper end surface of the outer wall 11 to the upper surface of the bottom 10. In addition, the shape of the notch 12 may be other than the groove shape.

  As shown in FIG. 4, in the branch member 1, the four cutout portions 12 are arranged in a circle at intervals of 90 degrees in a top view. Accordingly, in the four cutout portions 12, the two cutout portions 12 are disposed to face each other with the locking structure 13 interposed therebetween, and the remaining two cutout portions 12 sandwich the locking structure 13 therebetween. Are arranged opposite each other. Hereinafter, for convenience of description, the four cutout portions 12 arranged in a circle are referred to as “cutout portions 12a to 12d” in the clockwise direction in the top view as shown in FIGS. There is.

  The locking structure 13 includes a base portion 130 and a pair of locking portions 131 supported by the base portion 130. The base 130 has a hollow cylindrical shape, and is erected at the center of the upper surface of the bottom 10 so as to surround the through hole 10 a of the bottom 10. A cylindrical hollow portion 130 a penetrating the base portion 130 is connected to the through hole 10 a of the bottom portion 10. The through hole 10 a of the bottom 10 and the hollow portion 130 a of the base 130 connected thereto constitute a cylindrical through hole 14 that penetrates the bottom 10 and the locking structure 13. The through hole 14 extends from the lower surface of the bottom portion 10 to the upper surface of the base portion 130.

  The pair of locking portions 131 extend from the upper end surface of the base portion 130 in a direction perpendicular to the upper end surface, and are arranged to face each other. That is, as shown in FIG. 4, the pair of locking portions 131 are arranged at an interval of 180 degrees on the circular upper end surface of the base portion 130 in the top view of the branching member 1. And a pair of latching | locking part 131 is inserted in the attachment hole of an attachment target object, and latches to the said attachment hole so that it may not come out of the said attachment hole.

  A locking head 132 is provided at the tip of each of the pair of locking portions 131 so as to protrude outward. Each of the locking heads 132 of the pair of locking portions 131 includes an inclined surface 132a that hits the periphery of the mounting hole when the pair of locking portions 131 are inserted into the mounting holes of the mounting target, and the pair of locking portions 131, respectively. When the locking part 131 is inserted into the mounting hole of the mounting object, it has a locking surface 132b that locks to the peripheral part of the mounting hole in the mounting object. The inclined surface 132a is a curved surface, and the locking surface 132b is a flat surface. The pair of locking portions 131 can be elastically deformed so that their locking heads 132 approach each other. In addition, as shown in FIG. 4, in a top view of the branching member 1, the pair of locking portions 131 of the locking structure 13 and the two notch portions disposed to face each other with the locking structure 13 interposed therebetween. 12a and 12c are arranged in a straight line.

  The hollow portion 130 a of the base portion 130 is connected to the facing space 131 a between the pair of locking portions 131 supported by the base portion 130. In each of the pair of locking portions 131, the opposing curved surface 131 b of the locking portion 131 and the other locking portion 131 that forms a pair with the locking portion 131 is connected to the inner curved surface 130 b of the base portion 130. And the curvature radius of each opposing curved surface 131b of a pair of latching | locking part 131 and the curvature radius of the inner side curved surface 130b of the base part 130 correspond, As shown in FIG. The arc formed by 131b overlaps the circle formed by the inner curved surface 130b.

  In each of the pair of locking portions 131, the outer curved surface 131 c of the locking portion 131 where the locking head 132 is not formed is connected to the outer curved surface 130 c of the base portion 130. The curvature radii of the outer curved surfaces 131c of the pair of locking portions 131 coincide with the curvature radii of the outer curved surfaces 130c of the base 130, and as shown in FIG. 4, the outer curved surfaces 131c are formed in a top view. The arc overlaps with a circle formed by the outer curved surface 130c.

  In the branch member 1 having the above-described structure, as illustrated in FIG. 7, the electric wire 200 of the wire harness 100 is passed through each notch portion 12. Specifically, two electric wires 200a and 200b are passed through one notch 12a out of two notches 12a and 12b adjacent to each other in the circumferential direction of the outer wall 11 in a top view of the branch member 1, By passing two electric wires 200c and 200d through the other notch 12b, four electric wires 200a to 200d are introduced into the branch member 1 from the two notches 12a and 12b. Of the remaining two cutout portions 12c and 12d, the two electric wires 200a and 200b are passed through one cutout portion 12d, and the two electric wires 200c and 200d are passed through the other cutout portion 12c. Thus, the four electric wires 200a to 200d are led out of the branch member 1 from the two notches 12c and 12d.

  The electric wires 200b and 200c are taken out of the branch member 1 from the notches 12d and 12c, respectively, and become branch lines 111b. Further, when the electric wire 200a is taken out from the notch 12d to the outside of the branching member 1, the electric wire 200a is bent at about 90 degrees on the side wall of the notch 12d to become a branch line 111a. When the electric wire 200d is taken out from the notch 12c to the outside of the branching member 1, the electric wire 200d is bent at about 90 degrees on the side wall of the notch 12c to form a branch line 111c. In addition, when the electric wire 200 is bent by the side wall of the notch portion 12, the electric wire 200 is less likely to float due to friction between the electric wire 200 and the side wall, and the lid member 50 is not attached to the branch member 1. The electric wire 200 is unlikely to jump out of the branch member 1.

  In the present embodiment, the branching member 1 is configured such that the electric wires 200a and 200d whose distances are desired to be as large as possible are not passed through the same notch 12 and the electric wires 200a and 200b do not intersect in the branching member 1. In this case, the distance between the electric wires 200a and 200d is increased. As shown in FIG. 7, the electric wire 200a passes through the notches 12a and 12d, the electric wire 200d passes through the notches 12b and 12c, and the electric wires 200a and 200d do not intersect with each other in the branch member 1. . Thereby, in the branch member 1, the electric wires 200a and 200d are arranged away from each other with the locking structure 13 interposed therebetween.

  As described above, the branch member 1 through which the plurality of electric wires 200a to 200d constituting the wire harness 100 is passed is attached to the attachment object after the lid member 50 is attached. FIG. 8 is a diagram illustrating a state in which the branch member 1 to which the lid member 50 is attached is attached to the stay 300 that is an attachment object. The stay 300 is a member attached to the vehicle. The attachment object to which the branch member 1 is attached may be another member.

  When the branching member 1 is attached to the stay 300, a pair of engagements of the locking structure 13 of the branching member 1 from the one main surface 300 b side of the stay 300 with respect to the attachment hole 310 provided in the stay 300. A stop 131 is inserted. The attachment hole 310 penetrates the stay 300 in the thickness direction.

  The pair of locking portions 131 enter the mounting holes 310 while the inclined surfaces 132 a of the locking heads 132 hit the peripheral edge of the mounting holes 310 of the stay 300. Thereby, a pair of latching | locking part 131 approachs the attachment hole 310, elastically deforming so that those latching heads 132 may mutually approach. When the pair of locking portions 131 are inserted into the mounting holes 310 of the stay 300 until their locking heads 132 come out to the other main surface 300a side of the stay 300, the elasticity of the pair of locking portions 131 is reached. The deformation is released, and as shown in FIG. 9, the locking surface 132 b of the locking head 132 is locked to the peripheral portion of the mounting hole 310 on the other main surface 300 a of the stay 300. become. Thereby, the locking structure 13 is locked in the mounting hole 310 of the stay 300, and the branch member 1 is mounted on the stay 300. FIG. 9 shows a cross-sectional structure of the stay 300 at the mounting hole 310.

  In addition, about the electric wires 200a and 200d which want to keep the mutual distance as much as possible, the electric wire holding structure described in the above-mentioned patent document 4 is used between the connector 60a and the branch member 1, and the electric wires 200a and 200d. You may hold | maintain the distance between predetermined size or more.

  Further, in order to make it difficult for the electric wire 200 passed through the notch 12 to jump out of the branching member 1, the size of each notch 12 depends on the thickness and the number of the electric wires 200 passed through the notch 12. It is desirable to decide accordingly. For example, when ten electric wires 200 having a diameter of 0.3 mm to 0.5 mm are passed through a certain notch 12, the height (depth) and width of the notch 12 are each 10 mm. And 5 mm are desirable. Thereby, it can suppress that a clearance gap produces between the said notch part 12 and the said electric wire 200, and the said electric wire 200 becomes difficult to jump out of the branch member 1. FIG.

  In the above example, the lid member 50 that covers the opening 15 on the upper surface of the branching member 1 is attached to the branching member 1 so that the electric wire 200 passed through the branching member 1 does not jump out. A tape or the like may be applied to the branch member 1 so as to cover the opening 15 on the upper surface of the member 1.

  In the above example, the wire harness 100 is branched into three, but may be branched into two, or may be branched into four or more.

  As described above, in the branch member 1 according to the present embodiment, the four cutout portions 12 are provided on the outer wall portion 11, so that the four cutout portions 12 are used as described above. The wire harness 100 can be branched while separating the electric wires 200 that are desired to be separated from each other as much as possible. If the four cutout portions 12 are provided for the outer wall portion 11, the cutout portions 12 for introducing the two electric wires 200 into the branching member 1 can be provided for each electric wire 200. Since notches 12 for leading the electric wires 200 from the branching member 1 to the outside can be provided for each electric wire 200, at least four cuts are made with respect to the outer wall portion 11 in order to separate the two electric wires 200. The notch part 12 should just be provided. In order to separate the three or more electric wires 200 from each other, six or more cutout portions 12 may be provided on the outer wall portion 11.

  Moreover, in this Embodiment, the branch number and branch direction of the wire harness 100 can be easily changed by changing the number and position of the notch part 12 provided in the outer wall part 11. FIG.

  Moreover, in this Embodiment, since the latching structure 13 latched to the attachment hole of the attachment target object to which the branch member 1 is attached is provided, the branch member 1 can be easily attached to an attachment target object. .

  In addition, when the electric wire 200 is used as a shield wire in order to make it less likely to be affected by noise from other electric wires 200 or to make it difficult to generate noise from itself, the drain wire is connected to the drain wire for grounding. Processing is required. It is difficult to automate this processing, and usually the processing is performed manually. In the present embodiment, the branch members 1 can separate the electric wires 200 to be separated from each other as much as possible, so that the electric wires 200 do not need to be shielded wires. When the electric wire 200 is not used as a shielded wire, the processing of the drain wire is not necessary, and thus the manufacturing of the wire harness 100 with a branching member can be automated. In addition, although automation of manufacture of the wire harness 100 with a branching member becomes difficult, when the distance between the electric wires 200 is not enough only by the branching member 1, the said electric wire 200 is good also as a shield wire.

  Moreover, in this Embodiment, the some branch member 1 can be mutually connected. FIG. 10 is a diagram illustrating a state where two branch members 1 are connected. FIG. 11 is a diagram showing a cross-sectional composition of the two branch members 1 when the two branch members 1 connected to each other are cut along the plane 400 shown in FIG. In FIG. 11, the cross-sectional structure of the lower branching member 1 is indicated by a diagonal line rising to the right, and the cross-sectional structure of the upper branching member 1 is indicated by a diagonal line that descends to the right.

  When the two branch members 1 are connected to each other, the locking structure 13 of one branch member 1 is connected to the bottom 10 and the through-hole 14 penetrating the locking structure 13 provided in the other branch member 1. To insert from the back side of the bottom 10. At this time, in a state where one branch member 1 is rotated 90 degrees with respect to the other branch member 1, the locking structure 13 of the one branch member 1 is inserted into the through hole 14 of the other branch member 1. insert. That is, in a top view, the direction in which the pair of locking portions 131 of the one branching member 1 is aligned is perpendicular to the direction in which the pair of locking portions 131 of the other branching member 1 is aligned. The locking structure 13 of the branch member 1 is inserted into the through hole 14 of the other branch member 1. Then, until the upper end surface of the outer wall portion 11 of one branch member 1 hits the back surface of the bottom portion 10 of the other branch member 1, the locking structure 13 of the one branch member 1 penetrates the other branch member 1. When inserted into the hole 14, the locking structure 13 is locked to the through hole 14. Specifically, the locking heads 132 of the pair of locking portions 131 included in the locking structure 13 of one branch member 1 are exposed from the upper end surface of the base 130 of the locking structure 13 of the other branch member 1. Thus, the locking head 132 is locked to the upper end surface of the base 130. Thereby, one branch member 1 is attached to the other branch member 1, and both are connected. When the certain branch member 1 is attached to the other branch member 1 by the locking structure 13 of the branch member 1 being locked in the through hole 14 of the other branch member 1, the other branch member 1 is attached. Reference numeral 1 is an attachment object for the certain branch member 1, and the through hole 14 of the other branch member 1 is an attachment hole of the attachment object.

  In addition, in the branch member 1, since the four notches 12 are provided every 90 degrees, even if the branch member 1 is rotated 90 degrees, the branch member 1 before the rotation and the branch member 1 after the rotation are rotated. In this case, the positions of the four notches 12 coincide.

  Thus, in this Embodiment, since the some branch member 1 can be connected, a some temporary connection harness is produced using the some branch member 1, and the said some temporary connection harness is those The branching members 1 can be combined by connecting them. Therefore, manufacture of the wire harness 100 becomes easy. Below, the manufacturing method of this wire harness 100 is demonstrated. Below, the method to manufacture the wire harness 100 as shown by FIG. 12 is demonstrated as an example. Hereinafter, in order to distinguish the wire harness 100 shown in FIG. 12 from the wire harness 100 shown in FIG. 1, it is referred to as a “second wire harness 100”.

  The second wire harness 100 includes seven electric wires 200a to 200g. In the second wire harness 100, the trunk line 110 is branched into three branch lines 111a to 111c by the two branch members 1 connected to each other. The branch line 111a is constituted by electric wires 200a and 200d, the branch line 111b is constituted by electric wires 200b, 200c, 200e, and 200f, and the branch line 111c is constituted by an electric wire 200g.

  Moreover, when manufacturing the 2nd wire harness 100, as FIG. 14 shows, several electric wire 200d-200g is comprised of several branch member 1 among several electric wires 200a-200g which comprise the wire harness 100. The electric wires 200d to 200g are temporarily bundled through the notch 12, and the second temporary bundle harness 620 is produced. At this time, the electric wire 200d constituting the branch line 111a is bent at the side wall of the notch 12 passing therethrough, and the electric wire 200g constituting the branch line 111c is bent at the side wall of the notch 12 passing therethrough.

  In the second temporary binding harness 620, a terminal 500 is attached to one end of each of the electric wires 200d to 200g. A terminal 500 is attached to the other end of the electric wire 200d. Moreover, the terminal is attached to the other end of the electric wires 200e and 200f, and the connector 60c is attached to the other end of the electric wires 200e and 200f by inserting the terminal into the connector 60c. A terminal is attached to the other end of the electric wire 200g, and the connector 60d is attached to the other end of the electric wire 200g by inserting the terminal into the connector 60d.

  When the first temporary binding harness 610 and the second temporary binding harness 620 are produced as described above, the locking structure 13 of the branch member 1 of the first temporary binding harness 610 is replaced with the branch member 1 of the second temporary binding harness 620. The locking structure 13 is locked to the through hole 14. Thereafter, the terminal 500 attached to one end of the electric wires 200d to 200g is inserted into the connector 60a, the terminal 500 attached to the other end of the electric wire 200d is inserted into the connector 60b, and attached to the other end of the electric wires 200b and 200c. The terminal 500 is inserted into the connector 60c. Thereby, the wire harness 100 branched by the connected several branch member 1 as shown in FIG. 12 is completed.

  In addition, about the electric wires 200a and 200c which want to keep the mutual distance as much as possible, the electric wire holding structure described in the above-mentioned Patent Document 4 is used between the connector 60a and the branch member 1, and the electric wires 200a and 200c are connected. The distance may be maintained at a predetermined size or more.

  In the above example, the wire harness 100 is branched using the two connected branch members 1. However, the wire harness 100 may be branched using three or more connected branch members 1. . In this case, the same number of temporary binding harnesses as the number of branch members 1 to be connected and used are produced, and the wire harness 100 is manufactured by connecting the branch members 1 of these temporary binding harnesses.
