Description

[Technical Field]

[0001] The present invention relates to a harness routing structure. [Background technology]

[0002] Conventionally, elastically deformable harnesses are known that are routed from electronic control devices. When both ends of the harness are connected to connection terminals, a bend may occur due to the excess length of the harness. This bend may come into contact with other components.

[0003] [Patent Document 1] Patent Publication No. 2021-15921 Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present invention is to provide a harness routing structure that prevents contact with other components by suppressing bulging of a curved portion that occurs when the harness is connected. [Means for solving the problem]

[0005] In order to achieve the above-mentioned object, a harness routing structure according to an embodiment of the present invention includes, for example, a cover having an elastically deformable harness, a guide portion that bends the harness, and a rotating portion that allows the guide portion to rotate, and when the harness is connected to a connection terminal, the rotating portion stops rotating at a predetermined angle, thereby restricting the elastic deformation of the harness.

[0006] With this configuration, when the harness elastically deforms, the rotating part stops, thereby restricting the elastic deformation of the harness, thereby reducing the bulge caused by the harness bending when connected and preventing contact with other components.

[0007] Furthermore, a harness routing structure according to an embodiment of the present invention includes, for example, a cover having an elastically deformable harness, a guide portion that bends the harness, a rotating portion that allows the guide portion to rotate, and a stopper that maintains the guide portion at a predetermined angle, and when the harness is connected to a connection terminal, the stopper abuts against the guide portion to restrict elastic deformation of the harness.

[0008] According to this configuration, for example, when the harness elastically deforms, the guide portion is maintained by the stopper, thereby restricting the elastic deformation of the harness, thereby reducing outward bulging of the harness.

[0009] Furthermore, in a harness routing structure according to an embodiment of the present invention, for example, the cover may have a main body portion that covers the base of the harness and a guide portion extending from the main body portion, and the guide portion may have a downward extension portion that bends downward, and a first inclined portion that bends at a gentler incline than the downward extension portion between the pivoting portion and the downward extension portion.

[0010] According to this configuration, for example, when the guide portion rotates, it is possible to prevent the first inclined portion from interfering with the stopper before the downward extending portion and the stopper come into contact with each other.

[0011] Furthermore, in the harness routing structure according to the embodiment of the present invention, for example, the guide portion may include a second inclined portion inclined upward from the rotating portion between the rotating portion and the first inclined portion.

[0012] According to this configuration, for example, since the second inclined portion is provided, it is possible to prevent interference between the second inclined portion of the guide portion and other components.

[0013] Furthermore, in the harness routing structure according to an embodiment of the present invention, for example, the harness may have a main harness and a sub-harness branching off from the main harness, and the guide portion may include a sub-guide portion extending to the position where the sub-harness branches off.

[0014] According to this configuration, for example, the extending direction of the sub-harness can be adjusted by extending the sub-guide portion to the branching position. [Effects of the Invention]

[0015] According to the present invention, it is possible to provide a harness routing structure that prevents contact with other components by suppressing the curved portion that occurs when the harness is connected. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, a harness 10 connected to an electronic control unit 50 mounted on a vehicle 100 is taken as an example. The vehicle 100 accommodates the electronic control unit 50 in, for example, an engine compartment. The harness 10 of this embodiment is taken as an example of a harness connecting the electronic control unit 50 to a power unit side.

[0018] As shown in the drawings, for convenience, the present specification defines an X-axis, a Y-axis, and a Z-axis. The X-axis, the Y-axis, and the Z-axis are perpendicular to one another. The X-axis is set along the longitudinal direction of the vehicle 100. The Y-axis is set along the width direction of the vehicle 100. The Z-axis is set along the vertical direction.

[0019] Furthermore, in this specification, the X direction, Y direction, and Z direction are defined. The X direction is a direction along the X axis, and includes the +X direction indicated by the X axis arrow and the -X direction opposite to the X axis arrow. The Y direction is a direction along the Y axis, and includes the +Y direction indicated by the Y axis arrow and the -Y direction opposite to the Y axis arrow. The Z direction is a direction along the Z axis, and includes the +Z direction indicated by the Z axis arrow and the -Z direction opposite to the Z axis arrow.

[0020] In the following description, the +X direction is defined as the front in the longitudinal direction, and the -X direction is defined as the rear. The +Y direction is defined as the inside in the width direction, and the -Y direction is defined as the outside. The +Z direction is defined as the upward vertical direction, and the -Z direction is defined as the downward vertical direction. Note that the Z direction may differ from the vertical direction depending on various conditions such as the location where the vehicle 100 is located and the condition of the tires.

[0021] 1 is an exemplary schematic front perspective view showing a harness routing configuration according to an embodiment. As shown in FIG. 1, a harness 10 includes a main harness 11, a sub-harness 12 branching from the main harness 11, a cover 20 covering the main harness 11, and a connector 41 connected to an electronic control device 50.

[0022] One end (upper portion) of the main harness 11 is equipped with a connector 41 and is connected to a connection terminal 51 of the electronic control device 50 via the connector 41. The other end (lower portion) of the main harness 11 is connected to a connection terminal on the power unit side via another connector (not shown).

[0023] Here, the electronic control device 50 is mounted, for example, in an engine compartment of the vehicle 100 and fixed to the vehicle body. As an example, the electronic control device 50 is an EFI-ECU (Electrical Fuel Injection-Electronic Control Unit). Note that the electronic control device 50 may be, for example, another electronic component such as an electrical junction box to which the harness 10 is connected. Alternatively, the electronic control device 50 may be not only an electronic component but also a vehicle component to which the harness 10 can be connected.

[0024] The electronic control device 50 has, for example, three connection terminals provided on the top surface. Specifically, a connection terminal 51, a second connection terminal 52, and a third connection terminal 53 are provided. The three connection terminals are aligned in a row in the width direction (Y direction). It is sufficient that at least one connection terminal is provided.

[0025] The connection terminal 51 is located on the inside in the width direction (+Y direction) and is connected to the connector 41 of the harness 10. The second connection terminal 52 is located at the center in the width direction and is connected to the second connector 42 of the sub-harness 12. The third connection terminal 53 is located on the outside in the width direction (-Y direction) and is connected to the third connector 43.

[0026] Here, the order in which the connectors are connected to the electronic control device 50 will be described. They are connected in the order of the outside, center, and inside in the width direction. In other words, the third connector 43, the second connector 42, and the connector 41 are connected in this order.

[0027] Next, a procedure for connecting a connector to the connection terminal of the electronic control device 50 will be described. An example will be taken of a case where connector 41 is connected to connection terminal 51. Note that before connector 41, another connector (not shown) located on the opposite side of connector 41 is connected to the power unit side.

[0028] First, the connector 41 is aligned with the connection terminal 51, and the connector 41 is inserted and locked. Next, with the connector 41 in the inserted position, the lever 411 is rotated from the +Y direction to the -Y direction. This causes the connector 41 to move downward and connect to the connection terminal 51. Furthermore, in conjunction with the downward movement of the connector 41, the harness 10 also moves downward.

[0029] The same procedure is used to connect the second connector 42 to the second connection terminal 52. The same procedure is used to connect the third connector 43 to the third connection terminal 53.

[0030] As a result of connecting both ends of the harness 10, the excess length of the harness 10 is curved due to elastic deformation of the harness 10. This may cause the excess length of the curved harness 10 to interfere with other components.

[0031] However, in this embodiment, when connected, the rotating portion 22 rotates together with the guide portion 21 and stops at a predetermined angle. Therefore, the guide portion 21 can restrict elastic deformation of the harness 10. As a result, bending of the harness 10 can be reduced.

[0032] Next, the harness 10 of this embodiment will be described in detail.

[0033] The main harness 11 is, for example, an elastically deformable harness 10 connected to the electronic control device 50. Because it is elastically deformable, it is a harness that is difficult for workers to bend during assembly. The main harness 11 has a connector 41 that is connected to a connection terminal 51 of the electronic control device 50. It also has another connector (not shown) that is connected to a connection terminal on the power unit side.

[0034] The sub-harness 12, for example, branches off from a part of the main harness 11. The branched end of the sub-harness 12 has a second connector 42 that is connected to a second connection terminal 52 in the center of the electronic control device 50. The sub-harness 12 has a smaller diameter than the main harness 11.

[0035] Connector 41 may have, for example, a lever 411 for connecting with connection terminal 51. In this way, it may be a lever-type connector 41. Similarly, second connector 42 may have a second lever 421 for connecting second connector 42 to second connection terminal 52. Furthermore, third connector 43 may have a third lever 431 for connecting third connector 43 to third connection terminal 53. Note that the connector may not have a lever.

[0036] Lever 411 can be rotated, for example, from the +Y direction to the -Y direction around hinge shaft 412 to move connector 41 downward and connect and fix it to connection terminal 51. Lever 411 makes connector 41 less likely to come off than if there were no lever. The same applies to second lever 421 and third lever 431.

[0037] Like lever 411, second lever 421 can be rotated from the +Y direction to the −Y direction around second hinge shaft 422, thereby moving second connector 42 downward and connecting and fixing it to second connection terminal 52. Similarly, third lever 431 can be rotated from the +Y direction to the −Y direction around third hinge shaft 432, thereby moving third connector 43 downward and connecting and fixing it to third connection terminal 53.

[0038] The cover 20 includes a main body portion 24, a guide portion 21, a rotating portion 22, and a stopper 23. The guide portion 21 includes a sub-guide portion 25, a downward extending portion 210, a first inclined portion 211, and a second inclined portion 212. The cover 20 is assembled integrally with the harness 10.

[0039] The main body 24 covers, for example, the base of the main harness 11 on the side connected to the connection terminal 51. The main body 24 is attached to the connector 41 and has, as an example, a box shape that covers the side, top, and rear surfaces of the main harness 11.

[0040] The guide portion 21 changes the extending direction of the main harness 11 and bends the main harness 11, for example, by contacting the main harness 11. The guide portion 21 extends from the main body portion 24. The guide portion 21 is rotatable by the rotating portion 22.

[0041] The pivoting portion 22 is provided, for example, between the main body portion 24 and the guide portion 21. The pivoting portion 22 may be a portion of the cover 20 where the plate thickness is reduced, thereby allowing the guide portion 21 to be pivotable. Alternatively, the pivoting portion 22 may be formed of a hinge made of metal or the like. Alternatively, the pivoting portion 22 may be provided with a mechanism that stops it at a predetermined angle.

[0042] The stopper 23 is, for example, a frame-like shape formed by a pair of extensions connected from the main body 24. The stopper 23 is a frame-like shape that surrounds the guide portion 21 from the outside. It maintains the guide portion 21 at a predetermined angle. That is, when the guide portion 21 has rotated to the predetermined angle, the downward extension 210 of the guide portion 21 abuts against the stopper 23 and is maintained in that position. This maintains the angle of the guide portion 21 at the predetermined angle, and rotation can be restricted.

[0043] The sub-guide portion 25 extends, for example, from a part of the guide portion 21 along the branching portion of the sub-harness 12. The sub-guide portion 25 makes it possible to adjust the branching direction of the sub-harness 12 by adjusting the angle at which it extends from the guide portion 21.

[0044] The downward extending portion 210 is, for example, a portion of the guide portion 21 that descends in the -Z direction, and serves as an abutment surface that abuts against the main harness 11. Therefore, the downward extending portion 210 abuts against the main harness 11, thereby bending the main harness 11 and changing the extension direction. When the +Y side surface of the downward extending portion 210 abuts against the stopper 23, the guide portion 21 comes to a standstill, and the rotation of the main harness 11 is restricted.

[0045] The downward extending portion 210 may support the main harness 11 with a cable tie or the like, and may be provided with a pair of through holes 213 through which the cable tie passes. Similarly, the sub-guide portion 25 may support the sub-harness 12 with a cable tie or the like, and may be provided with a pair of through holes 251 through which the cable tie passes.

[0046] The first inclined portion 211 is, for example, an inclined portion extending diagonally downward from the second inclined portion 212. It extends downward at a gentler inclination than the downward extending portion 210. The downward extending portion 210 extends further from the lower end of the first inclined portion 211. The first inclined portion 211 is an inclined surface that avoids interference with the stopper 23 when the guide portion 21 rotates.

[0047] The second inclined portion 212 is, for example, an inclined portion that extends obliquely upward from the rotating portion 22 when the main harness 11 is in a position after connection. The first inclined portion 211 extends obliquely downward from the obliquely upper end of the second inclined portion 212. The second inclined portion 212 is an inclined surface that avoids interference with the lever 411 when the lever 411 is in a position before rotation.

[0048] Next, with reference to FIGS. 2 and 3, the movements of the guide portion 21 and the main harness 11 before and after connecting the connector 41 of the main harness 11 to the connection terminal 51 of the electronic control device 50 will be described.

[0049] FIG. 2 is an exemplary schematic front view showing the configuration of the harness according to the embodiment before it is connected to the electronic control device 50. As shown in FIG.

[0050] 2, the main harness 11 includes a connector 41 connected to a connection terminal 51 of the electronic control device 50 and another connector on the opposite side. First, the other connector is connected to the connection terminal on the power unit side. Next, the connector 41 is connected to the connection terminal 51 of the electronic control device 50.

[0051] Before the connector 41 is connected to the connection terminal 51, the guide portion 21 is rotated in the −Z direction by an operator or the like. This causes the downward extension portion 210 to move in the −Y direction, and the main harness 11 also moves in the −Y direction.

[0052] Therefore, as shown in Figure 2, the main harness 11 has a first curved portion 111 that curves when it comes into contact with the downward extension portion 210, and a second curved portion 112 that is generated when it is pushed by the downward extension portion 210 by rotating the guide portion 21.

[0053] The first curved portion 111 is located between the downward extending portion 210 and the second inclined portion 212. The second curved portion 112 is located lower than the first curved portion 111 and the downward extending portion 210. The second curved portion 112 is located further in the -Y direction than the first curved portion 111.

[0054] With the main harness 11 bent by a worker or the like, the connector 41 is aligned with the connection terminal 51, inserted and locked. Next, with the connector 41 in the inserted position, the lever 411 is rotated from the +Y direction to the -Y direction.

[0055] As a result, the connector 41 moves down in conjunction with the operation of the lever 411, so that it is connected to and fixed in place by the connection terminal 51. At this time, when the connector 41 moves down, the main harness 11 also moves down by the same amount.

[0056] FIG. 3 is an exemplary schematic front view showing the configuration after the harness routing according to the embodiment is connected to the electronic control device 50. As shown in FIG.

[0057] 3, when the connector 41 is connected to the connection terminal 51, both ends of the main harness 11 are connected. At this time, the amount of downward displacement of the main harness 11 becomes excess length, and the excess length is elastically deformed.

[0058] That is, in this embodiment, the second curved portion 112 moves in the +Y direction due to elastic deformation. When the second curved portion 112 moves, the downward extending portion 210 rotates and comes into contact with the stopper 23 at a predetermined angle.

[0059] As a result, after connection, the second curved portion 112 becomes straight or curves with a larger circle of curvature than before connection. Therefore, when the downward extending portion 210 abuts against the stopper 23, the main harness 11 is positioned in the -Y direction relative to the extension direction of the downward extending portion 210, so that the main harness 11 can be prevented from bending in the +Y direction and interference with other components can be prevented.

[0060] (Variation) In one example of this embodiment, the downward extending portion 210 abuts against the stopper 23 to suppress bending of the main harness 11. On the other hand, in a modified example, the bending of the main harness 11 is suppressed by providing a mechanism that stops the rotating portion 22 at a predetermined angle.

[0061] As the second curved portion 112 moves in the +Y direction due to elastic deformation, the downward extending portion 210 also moves in the +Y direction. As a result, the rotating portion 22 rotates in the +Z direction and stops at a predetermined angle. In this case, even if the cover 20 does not have the stopper 23, the bending of the main harness 11 can be suppressed.

[0062] (Effects of this embodiment) As described above, the harness routing structure according to this embodiment includes, for example, the cover 20 having the elastically deformable harness 10, the guide portion 21 that bends the harness 10, and the pivot portion 22 that allows the guide portion 21 to rotate. When the harness 10 is connected to the connection terminal 51, the pivot portion 22 stops rotating at a predetermined angle, thereby restricting the elastic deformation of the harness 10. Thus, for example, when the harness 10 elastically deforms, the pivot portion 22 stops, thereby restricting the elastic deformation of the harness 10. As a result, outward bulging of the harness 10 can be reduced. Furthermore, the outward bulging can reduce interference with nearby components. An example of such a component is a brake reservoir tank.

[0063] Furthermore, a harness routing structure according to an embodiment of the present invention includes, for example, an elastically deformable harness 10, a cover 20 having a guide portion 21 that bends the harness 10, a rotating portion 22 that allows the guide portion 21 to rotate, and a stopper 23 that maintains the guide portion 21 at a predetermined angle, and when the harness 10 is connected to the connection terminal 51, the stopper 23 abuts against the guide portion 21 to restrict elastic deformation of the harness 10. Thus, for example, when the harness 10 elastically deforms, the stopper 23 abuts against the guide portion 21, thereby restricting elastic deformation of the harness 10. As a result, outward bulging of the harness 10 can be reduced.

[0064] Furthermore, in the harness routing structure according to the embodiment of the present invention, for example, the cover 20 may have a main body portion 24 that covers a base portion of the harness 10 and a guide portion 21 extending from the main body portion 24, and the guide portion 21 may include a downward extending portion 210 that bends downward, and a first inclined portion 211 that bends at a gentler inclination than the downward extending portion 210, between the rotating portion 22 and the downward extending portion 210. This makes it possible to prevent the first inclined portion 211 from interfering with the stopper 23, for example, when the guide portion 21 rotates, before the downward extending portion 210 and the stopper 23 come into contact with each other.

[0065] Furthermore, in the harness routing structure according to the embodiment of the present invention, for example, the guide portion 21 may include a second inclined portion 212 inclined upward from the rotating portion 22 between the rotating portion 22 and the first inclined portion 211. With this, for example, the presence of the second inclined portion 212 can prevent interference between other components and the second inclined portion 212 of the guide portion 21.

[0066] Furthermore, in the harness routing structure according to the embodiment of the present invention, for example, the harness 10 may have a main harness 11 and a sub-harness 12 branching off from a part of the main harness 11, and the guide portion 21 may include a sub-guide portion 25 extending to the branching position of the sub-harness 12. In this way, for example, the extending direction of the sub-harness 12 can be adjusted by the sub-guide portion 25 extending to the branching position.

[0067] Although the embodiments of the present invention have been described above, the above-described embodiments are presented as examples. This novel embodiment is not intended to limit the scope of the present invention. The present invention can be embodied in various other forms without departing from the spirit of the invention. Various omissions, substitutions, and modifications can be made within the scope of the present invention. The scope of the invention and its equivalents as defined in the claims are included in the scope and spirit of the invention. Included in. [Explanation of symbols]
