Summary of the Invention

Problems to be Solved by the Invention

[0004] One object of the present invention is to provide a harness cable structure that avoids contact with other components by suppressing the swelling of the curved portion generated when the harness is connected.

Means for Solving the Problems

[0005] To achieve the above object, a harness cable structure according to an embodiment of the present invention includes, for example, an elastically deformable harness, The main body covers the base of the harness, a guide portion for bending the harness, The main body and the guide are formed integrally, and relative to the main body a cover having a rotating portion that enables the guide portion to rotate, and when the harness is connected to the connection terminal, the rotating portion Position the harness on the rotating part side of the guide part. stops rotating at an angle, In the direction from the rotating part to the guide part, it should be positioned on the rotating part side of the guide part. restricting the elastic deformation of the harness.

[0006] With this configuration, when the harness undergoes elastic deformation, the rotating part remains stationary, thereby restricting the elastic deformation of the harness. As a result, bulging caused by the bending of the harness during connection is reduced, and contact with other parts can be avoided.

[0007] Furthermore, the harness routing structure according to the embodiment of the present invention includes, for example, a harness that is elastically deformable, a cover having a guide portion that bends the harness, a rotating portion that makes the guide portion rotatable, and a stopper that maintains the guide portion at a predetermined angle, wherein the stopper restricts the elastic deformation of the harness by coming into contact with the guide portion when the harness is connected to a connection terminal.

[0008] With this configuration, for example, when the harness undergoes elastic deformation, the guide section can be maintained by a stopper to restrict the elastic deformation of the harness. As a result, the outward bulging of the harness can be reduced.

[0009] Furthermore, in the harness routing structure according to the 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 include a downwardly extending portion that bends downward and a first inclined portion between the rotating portion and the downward extending portion that bends at a gentler slope than the downward extending portion.

[0010] With this configuration, for example, when the guide part rotates, it is possible to prevent the first inclined part from interfering with the stopper before the downward extension part and the stopper come into contact.

[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 that is inclined upward from the rotating portion, between the rotating portion and the first inclined portion.

[0012] With this configuration, for example, because it has a second inclined portion, interference between the second inclined portion of the guide portion and other parts can be suppressed.

[0013] Furthermore, in the harness routing structure according to the embodiment of the present invention, for example, the harness may include 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 branching position of the sub-harness.

[0014] With this configuration, for example, the extension direction of the sub-harness can be adjusted by having the sub-guide section extend to the branching point. [Effects of the Invention]

[0015] According to the present invention, a harness routing structure can be provided that avoids contact with other components by suppressing the bending portion that occurs when the harness is connected. [Brief explanation of the drawing]

[Figure 2] Figure 2 is an illustrative and schematic front view showing the configuration of the harness according to the embodiment before it is connected to the electronic control device.

[Modes for carrying out the invention]

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

[0018] Here, as shown in each drawing, for convenience, the X-axis, Y-axis, and Z-axis are defined in this specification. The X-axis, Y-axis, and Z-axis are orthogonal to each other. The X-axis is provided along the longitudinal direction of the vehicle 100. The Y-axis is provided along the width direction of the vehicle 100. The Z-axis is provided along the vertical direction.

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

[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 inner side in the width direction, and the -Y direction is defined as the outer side. The +Z direction is defined as the upward direction in the vertical direction, and the -Z direction is defined as the downward direction in the vertical direction. Note that the Z-direction may be different from the vertical direction depending on various conditions such as the location where the vehicle 100 is located and the state of the tires.

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

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

[0023] Here, the electronic control unit 50 is, for example, mounted in the engine compartment of the vehicle 100 and fixed to the vehicle body. The electronic control unit 50 is, as an example, an EFI-ECU (Electrical Fuel Injection-Electronic Control Unit). The electronic control unit 50 may also be, for example, another electronic component such as an electrical junction box to which the harness 10 is connected. Alternatively, it may be a vehicle component to which the harness 10 can be connected, in addition to an electronic component.

[0024] The electronic control unit 50 has, for example, three connection terminals on its top surface. Specifically, it has a connection terminal 51, a second connection terminal 52, and a third connection terminal 53. The three connection terminals are arranged in a row in the width direction (Y direction). At least one connection terminal is required.

[0025] The first 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 in 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, we will explain the order in which the connectors are connected to the electronic control unit 50. They are connected in the order of outer, center, and inner in the width direction. That is, they are connected in the order of third connector 43, second connector 42, and connector 41.

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

[0028] First, the connector 41 is aligned with the connection terminal 51 and locked in place by inserting it. Next, with the connector 41 inserted, 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, the harness 10 also moves downward in conjunction with the downward movement of the connector 41.

[0029] The same procedure is followed when connecting the second connector 42 to the second connection terminal 52. The same applies when connecting the third connector 43 to the third connection terminal 53.

[0030] As a result of connecting both ends of harness 10, the excess length of harness 10 bends due to the elastic deformation of harness 10. This means that the bent excess length of harness 10 may interfere with other components.

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

[0032] Next, we will describe the details of the harness 10 of this embodiment.

[0033] The main harness 11 is, for example, an elastically deformable harness 10 connected to the electronic control unit 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 the connection terminal 51 of the electronic control unit 50. It also has other connectors (not shown) that are connected to the connection terminal on the power unit side.

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

[0035] Connector 41 may have, for example, a lever 411 for connecting to the connection terminal 51. Thus, it may be a lever-type connector 41. Similarly, the second connector 42 may have a second lever 421 for connecting the second connector 42 to the second connection terminal 52. Furthermore, the third connector 43 may have a third lever 431 for connecting the third connector 43 to the third connection terminal 53. Note that connectors without levers are also possible.

[0036] The lever 411 can be rotated, for example, from the +Y direction to the -Y direction around the hinge axis 412, thereby moving the connector 41 downwards and connecting and securing it to the connection terminal 51. The lever 411 makes it more difficult for the connector 41 to come loose than if there were no lever. The second lever 421 and the third lever 431 function similarly.

[0037] The second lever 421, like the lever 411, rotates around the second hinge axis 422 from the +Y direction to the -Y direction, thereby moving the second connector 42 downwards and connecting and securing it to the second connection terminal 52. Similarly, the third lever 431 rotates around the third hinge axis 432 from the +Y direction to the -Y direction, thereby moving the third connector 43 downwards and connecting and securing it to the third connection terminal 53.

[0038] The cover 20 comprises a main body 24, a guide portion 21, a rotating portion 22, and a stopper 23. The guide portion 21 comprises a sub-guide portion 25, a downward extension 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 that is connected to the connection terminal 51. The main body 24 is attached to the connector 41 and, as an example, has a box shape that covers the sides, top, and rear of the main harness 11.

[0040] The guide portion 21, for example, changes the extension direction of the main harness 11 by coming into contact with it, causing it to bend. The guide portion 21 extends from the main body portion 24 and is also rotatable by the rotating portion 22.

[0041] The rotating part 22 is provided, for example, between the main body 24 and the guide part 21. The rotating part 22 may be a thinned portion of the cover 20, thereby allowing the guide part 21 to rotate. It may also be formed from a hinge made of metal or the like. It may also be equipped with a mechanism to stop at a predetermined angle.

[0042] The stopper 23 is a frame shape formed, for example, by extending and connecting a pair from the main body 24. The stopper 23 is a frame 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 rotates to a predetermined angle, the downward extension portion 210 of the guide portion 21 abuts against the stopper 23 and is maintained. As a result, the angle of the guide portion 21 is maintained at a predetermined angle, and rotation can be restricted.

[0043] The sub-guide section 25 extends, for example, from a part of the guide section 21 along the branching section of the sub-harness 12. The sub-guide section 25 allows adjustment of the branching direction of the sub-harness 12 by changing the angle at which it extends from the guide section 21.

[0044] The downward extension 210 is, for example, the part of the guide portion 21 that extends downward in the -Z direction, and becomes the contact surface that abuts against the main harness 11. Therefore, the downward extension 210 can bend the main harness 11 by abutting against it, thereby changing the direction of extension. The +Y side surface of the downward extension 210 abuts against the stopper 23, which stops the guide portion 21 and restricts the rotation of the main harness 11.

[0045] The downward extension portion 210 may be used to support the main harness 11 with cable ties or the like, and may be provided with a pair of through holes 213 for passing cable ties through. Similarly, the sub-guide portion 25 may be used to support the sub-harness 12 with cable ties or the like, and may be provided with a pair of through holes 251 for passing cable ties through.

[0046] The first inclined portion 211 is, for example, an inclined portion that extends diagonally downward from the second inclined portion 212. It extends downward with a gentler slope than the downward extension portion 210. The downward extension portion 210 further extends 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 diagonally upward from the rotating portion 22 in the position after the main harness 11 has been connected. The first inclined portion 211 extends diagonally downward from the diagonally upward end of the second inclined portion 212. The second inclined portion 212 is an inclined surface that avoids interference with the lever 411 in the position before the lever 411 is rotated.

[0048] Next, using Figures 2 and 3, we will explain the movement of the guide section 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 unit 50.

[0049] Figure 2 is an illustrative and schematic front view showing the configuration of the harness according to the embodiment before it is connected to the electronic control device 50.

[0050] As shown in Figure 2, the main harness 11 includes a connector 41 that is connected to the connection terminal 51 of the electronic control unit 50 and another connector on the opposite side. First, the other connector is connected to the connection terminal on the power unit side. Next, connector 41 is connected to the connection terminal 51 of the electronic control unit 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 the guide portion 21 is rotated and pushed by the downward extension portion 210.

[0053] The first curved section 111 is located between the downward extension section 210 and the second inclined section 212. The second curved section 112 is located below the first curved section 111 and the downward extension section 210. The second curved section 112 is located in the -Y direction relative to the first curved section 111.

[0054] With the main harness 11 bent by the worker or other person, the connector 41 is aligned with the connection terminal 51 and locked in place by being inserted. 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, when the lever 411 is operated, the connector 41 lowers, connecting to and securing the connection terminal 51. At this time, when the connector 41 lowers, the main harness 11 also lowers by the same amount.

[0056] Figure 3 is an exemplary and schematic front view showing the configuration of the harness routing after it has been connected to the electronic control device 50 according to the embodiment.

[0057] As shown in Figure 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 displacement of the main harness 11 becomes the excess length, and this excess length undergoes elastic deformation.

[0058] In other words, in this embodiment, the second curved portion 112 moves in the +Y direction due to elastic deformation. As the second curved portion 112 moves, the downward extension 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 the curve becomes larger in radius than before connection. Therefore, because the downward extension portion 210 abuts against the stopper 23, the main harness 11 is positioned in the -Y direction more than the extension direction of the downward extension portion 210, thus suppressing the curvature of the main harness 11 in the +Y direction and suppressing interference with other parts.

[0060] (modified version) In one example of this embodiment, the downward extension portion 210 abuts against the stopper 23 to suppress the 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 in which the rotating portion 22 stops at a predetermined angle.

[0061] As the second curved portion 112 moves in the +Y direction due to elastic deformation, the downward extension 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, the curvature of the main harness 11 can be suppressed even if the cover 20 does not have a stopper 23.

[0062] (Effects of this embodiment) As described above, the harness routing structure according to this embodiment includes, for example, a harness 10 that is elastically deformable, a cover 20 having a guide portion 21 that bends the harness 10, and a rotating portion 22 that makes the guide portion 21 rotatable. The rotating portion 22 restricts the elastic deformation of the harness 10 by stopping its rotation at a predetermined angle when the harness 10 is connected to the connection terminal 51. As a result, for example, when the harness 10 is elastically deformed, the rotating portion 22 stops, thereby restricting the elastic deformation of the harness 10. Consequently, the outward bulging of the harness 10 can be reduced. Furthermore, interference with nearby parts can be reduced by preventing outward bulging. Examples of such parts include brake reservoir tanks.

[0063] Furthermore, the harness routing structure according to an embodiment of the present invention includes, for example, a harness 10 that is elastically deformable, a cover 20 having a guide portion 21 that bends the harness 10, a rotating portion 22 that makes the guide portion 21 rotatable, and a stopper 23 that maintains the guide portion 21 at a predetermined angle. The stopper 23 restricts the elastic deformation of the harness 10 by coming into contact with the guide portion 21 when the harness 10 is connected to the connection terminal 51. As a result, for example, when the harness 10 is elastically deformed, the elastic deformation of the harness 10 can be restricted by the contact between the stopper 23 and the guide portion 21.

[0064] Furthermore, in the harness routing structure according to the embodiment of the present invention, for example, the cover 20 has a main body portion 24 that covers the base of the harness 10 and a guide portion 21 extending from the main body portion 24, and the guide portion 21 may include a downwardly bent downward extension portion 210 and a first inclined portion 211 between the rotating portion 22 and the downward extension portion 210 that bends at a gentler slope than the downward extension portion 210. With this, for example, when the guide portion 21 rotates, it is possible to suppress interference between the first inclined portion 211 and the stopper 23 before the downward extension portion 210 and the stopper 23 come into contact.

[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 that is inclined upward from the rotating portion 22 between the rotating portion 22 and the first inclined portion 211. With this, for example, interference between other parts and the second inclined portion 212 of the guide portion 21 can be suppressed because of the presence of the second inclined portion 212.

[0066] Furthermore, in the harness routing structure according to the embodiment of the present invention, for example, the harness 10 may include a main harness 11 and a sub-harness 12 that branches off from a part of the main harness 11, and the guide portion 21 may include a sub-guide portion 25 that extends to the branching position of the sub-harness 12. With this configuration, for example, the extension direction of the sub-harness 12 can be adjusted by having the sub-guide portion 25 extend to the branching position.

[0067] The embodiments of the present invention have been described above, but the embodiments described above are presented as examples only. This invention is not intended to limit the scope of the present invention. This can be implemented in various other forms. Furthermore, without departing from the spirit of the invention, Within the scope, various omissions, substitutions, and modifications can be made. Furthermore, this embodiment is The scope of the invention and its equivalents as described in the claims, as well as the scope of the abstract and gist of the invention. It is included in.
