  • the bundle of electric wires includes a first bundle of electric wires and a second bundle of electric wires. Both the first bundle of electric wires and the second bundle of electric wires are arranged so as to bend inside the protector.
  • the thick electric wires increase the rigidity of the bundle of electric wires, making the bundle of electric wires difficult to bend. Therefore, in order to accommodate a bundle of electric wires containing thick electric wires in a bent state in a protector, the protector tends to become large.
  • the present inventor has been considering how to prevent the protector from becoming large when only one of the first and second bundles of electric wires contains thick electric wires.
  • the purpose of this disclosure is to provide a wire harness that makes it possible to prevent the protector from becoming too large.
  • the wire harness of the present disclosure is a wire harness including a first electric wire bundle and a second electric wire bundle, and a protector through which the first electric wire bundle and the second electric wire bundle pass, the first electric wire bundle including only thin electric wires having a conductor cross-sectional area of less than 5 square millimeters, and the second electric wire bundle including at least one thick electric wire having a conductor cross-sectional area of 5 square millimeters or more, the protector including an entrance through which both the first electric wire bundle and the second electric wire bundle pass, a first exit passage through which the first electric wire bundle passes, and a second exit passage through which the second electric wire bundle passes and adjacent to the first exit passage, and in a plan view of the protector, each of the axis of the first exit passage and the axis of the second exit passage extends in a direction intersecting the axis of the entrance, and the second exit passage is provided at a position farther away from the entrance than the first exit passage.
  • the wire harness disclosed herein makes it possible to prevent the protector from becoming too large.

  • FIG. 2 is an exploded perspective view showing the wire harness in the same embodiment.
  • FIG. 3 is a plan view showing the wire harness with the protector cover removed.

  • the protector of the present disclosure includes: [1] A wire harness comprising: a first electric wire bundle and a second electric wire bundle; and a protector through which the first electric wire bundle and the second electric wire bundle pass, wherein the first electric wire bundle includes only thin electric wires having a conductor cross-sectional area of less than 5 square millimeters, and the second electric wire bundle includes at least one thick electric wire having a conductor cross-sectional area of 5 square millimeters or more, the protector has an entrance through which both the first electric wire bundle and the second electric wire bundle pass, a first exit passage through which the first electric wire bundle passes, and a second exit passage through which the second electric wire bundle passes and adjacent to the first exit passage, wherein, in a plan view of the protector, an axis of the first exit passage and an axis of the second exit passage each extend in a direction intersecting with the axis of the entrance, and the second exit passage is provided
  • the axis of the first outlet passage and the axis of the second outlet passage each extend in a direction intersecting the axis of the inlet. Therefore, the first wire bundle has a bent portion immediately before entering the first outlet passage in the protector. Similarly, the second wire bundle has a bent portion immediately before entering the second outlet passage in the protector. And since the second outlet passage is provided at a position farther from the inlet than the first outlet passage, the bent portion of the second wire bundle is set at a position farther from the inlet than the bent portion of the first wire bundle. That is, the bent portion of the second wire bundle is disposed at a position on the outer side of the bent portion of the first wire bundle. Therefore, the bent portion of the second wire bundle, which includes thick wires, can have a larger radius of curvature depending on the high rigidity compared to the bent portion of the first wire bundle. Therefore, it is possible to suppress the size of the protector from increasing.
  • an axis of the first outlet passage and an axis of the second outlet passage may be parallel to each other in a plan view of the protector.

  • a second passage volume through which the second electric wire bundle passes may be configured to be larger than a first passage volume through which the first electric wire bundle passes. According to this configuration, it is possible to reduce the space required for bending the first bundle of electric wires having low rigidity, while ensuring a large space required for bending the second bundle of electric wires having high rigidity, thereby more suitably preventing the protector from becoming large.

  • the protector 12 has a protector body 40 having an opening 40a, and a cover 50 that covers the opening 40a of the protector body 40.
  • the protector body 40 has a first locking portion 47b.
  • the cover 50 has a second locking portion 51b that hooks onto the first locking portion 47b.
  • the second outlet passage 32 has, at one end in the longitudinal direction of the second outlet passage 32, a second outlet 35 that pulls out the second wire bundle 22 to the outside, and a second wire fixing portion 37 to which the second wire bundle 22 is fixed.
  • the first locking portion 47b and the second locking portion 51b are provided at a position between the second wire fixing portion 37 and the second outlet 35.
  • the first locking portion 47b and the second locking portion 51b that protrude to the outside of the protector 12 are not located on the opposite side of the second outlet 35 from the second wire fixing portion 37. This allows the protector 12 to be small near the end 30a of the main passage 30, while the second wire bundle 22 is arranged around the outside of the first wire bundle 21, making it possible to easily accommodate the second wire bundle 22 in the protector 12.
  • the first angle ⁇ 1 between the axis La of the inlet 33 and the axis L1 of the first outlet passage 31, and the second angle ⁇ 2 between the axis La of the inlet 33 and the axis L2 of the second outlet passage 32 are each set to an acute angle.
  • the first angle ⁇ 1 and the second angle ⁇ 2 are the same. With this configuration, in which the first angle ⁇ 1 and the second angle ⁇ 2 are the same, it is possible to ensure a large radius of curvature for the second wire bundle 22 including the thick wires 23 while preventing the protector 12 from becoming large.
  • the first outlet passage 31 has a first outlet 34 at one end in the length direction of the first outlet passage 31, through which the first wire bundle 21 is drawn out to the outside.
  • the second outlet passage 32 has a second outlet 35 at one end in the length direction of the second outlet passage 32, through which the second wire bundle 22 is drawn out to the outside.
  • the first distance D1 from the axis La of the inlet 33 to the first outlet 34 and the second distance D2 from the axis La of the inlet 33 to the second outlet 35 are set to different lengths. With this configuration, it is possible to make the position of the first outlet 34 and the position of the second outlet 35 different from each other in the direction along the path of the wire bundle 11. This makes it possible to set appropriate positions of the first outlet 34 and the second outlet 35 according to the external fixed positions P1 and P2. As a result, it is possible to improve the ease of assembly of the wire harness 10 including the protector 12 and the wire bundle 11.
  • the second distance D2 is shorter than the first distance D1.
  • the second wire bundle 22 including the thick wires 23 tends to have a higher rigidity than the first wire bundle 21, and is therefore less likely to bend. Therefore, it is desirable to ensure that the fixing stroke of the second wire bundle 22 is longer than the fixing stroke of the first wire bundle 21. Therefore, by making the second distance D2 shorter than the first distance D1, it becomes easier to ensure the fixing stroke of the second wire bundle 22. As a result, this can contribute to further improving the ease of assembly.
  • the axis L1 of the first outlet passage 31 and the axis L2 of the second outlet passage 32 may be non-parallel to each other.
  • the end face of the first outlet 34 and the end face of the second outlet 35 may be non-parallel to each other.
  • the first angle ⁇ 1 between the axis La of the inlet 33 and the axis L1 of the first outlet passage 31, and the second angle ⁇ 2 between the axis La of the inlet 33 and the axis L2 of the second outlet passage 32 may be set to 90° or an obtuse angle.
  • the first angle ⁇ 1 and the second angle ⁇ 2 may be different angles.
  • the second distance D2 may be longer than the first distance D1.
  • the first distance D1 and the second distance D2 may be equal to each other.
  • the protector 12 has two outlets in total, namely, one first outlet 34 and one second outlet 35.
  • the number of outlets is not limited to this, and the protector 12 may have three or more outlets.
  • the first locking portion 47 b and the second locking portion 51 b may be provided on the opposite side of the second outlet passage 32 from the second outlet 35 with respect to the second wire fixing portion 37 .
  • the cover 50 may be formed integrally with the protector body 40. In this case, the cover 50 may be rotatably connected to the protector body 40 via a hinge portion, for example.
  • the wire bundle 11 in the illustrated example may be referred to as a main wire bundle including a first wire bundle 21 and a second wire bundle 22.

Abstract

Chaque fil électrique inclus dans un premier faisceau de fils électriques (21) est un fil électrique mince (24) dont la section transversale de conducteur est inférieure à 5 millimètres carrés. Un second faisceau de fils électriques (22) comprend au moins un fil électrique épais (23) dont la section transversale de conducteur est supérieure ou égale à 5 millimètres carrés. Un protecteur (12) comprend une entrée (33) par laquelle passe un faisceau de fils électriques (11), un premier passage de sortie (31) par lequel passe le premier faisceau de fils électriques (21), et un second passage de sortie (32) par lequel passe le second faisceau de fils électriques (22) et qui est adjacent au premier passage de sortie (31). Dans la vue en plan du protecteur (12), la ligne axiale (L1) du premier passage de sortie (31) et la ligne axiale (L2) du second passage de sortie (32) s'étendent chacune dans une direction croisant la ligne axiale (La) de l'entrée (33). Le second passage de sortie (32) est situé plus loin de l'entrée (33) que le premier passage de sortie (31).
