[0014] Hereinafter, a control cable assembly and a mounting structure according to an embodiment of the present invention will be described with reference to the drawings.

[0015] (Implementation Method 1)

[0016] Figure 1 This is a perspective view showing a control cable assembly 1 according to Embodiment 1. The control cable assembly 1 according to this embodiment is used to transmit the operation of a shift lever to a transmission of a vehicle such as an automobile, for example, to perform a gear shift operation of the vehicle.

[0017] The control cable assembly 1 includes a control cable 11 (an example of a long member), an operating-side connecting portion 12 , a transmission-side connecting portion 13 , and a mounting structure 14 .

[0018] The control cable 11 transmits the operation of the shift lever to the transmission by connecting the shift lever to the transmission. The control cable 11 has an outer shell 21 and an inner cable 22. The outer shell 21 is in the shape of an elongated cylinder. The inner cable 22 is slidably inserted into the outer shell 21. The outer shell 21 and the inner cable 22 are flexible. The outer shell 21 can be, for example, an outer shell formed of resin, or an outer shell formed of resin and metal wire, but is not particularly limited. The inner cable 22 can be, for example, an inner cable formed by bundling a plurality of metal wires, or an inner cable formed by bundling a plurality of metal wires and covering the surface with resin, but is not particularly limited. In addition, in the case of the control cable 11 for the transmission, an outer shell 21 with an outer diameter of, for example, 8 mm or more and 9 mm or less is used.

[0019] The operating side connection part 12 is connected to one end of the inner cable 22. The operating side connection part 12 is connected to the shift lever. The transmission side connection part 13 is connected to the other end of the inner cable 22. The transmission side connection part 13 is connected to the transmission. The mounting structure 14 mounts the control cable 11 to the vehicle body. It should be noted that Figure 1 In the following figures, the operating-side connecting portion 12 side in the longitudinal direction of the control cable 11 is indicated by an arrow C1 , and the transmission-side connecting portion 13 side is indicated by an arrow C2 .

[0020] (Mounting structure 14)

[0021] Figure 2 1 is a side view showing the vicinity of the mounting structure 14 of the control cable assembly 1. The mounting structure 14 includes a protector 31, a fixing clamp 32 (an example of a fixing member), and a mounting clamp 33 (an example of a mounting member).

[0022] The protector 31 is arranged around the outer housing 21 of the control cable 11. The fixing clamp 32 fixes the protector 31 to the outer housing 21. The mounting clamp 33 mounts the protector 31 to the frame portion 100 (an example of an object) of the vehicle body. Figure 2 In FIG, a frame portion 100 of the vehicle body is indicated by a dotted line.

[0023] (Protector 31)

[0024] Figure 3 yes Figure 2 The protector 31 is formed of a rubber material, for example, ethylene propylene diene monomer (EPDM). The overall shape of the protector 31 is substantially cylindrical. Figure 2 and Figure 3 The center axis O of the protector 31 is shown in FIG. The center axis O is along the length direction of the control cable 11. Figure 3 As shown, the protector 31 has a through hole 31 a , and the control cable 11 is inserted through the through hole 31 a .

[0025] like Figure 2 As shown, the protector 31 includes a cylindrical portion 41 , a first protrusion portion 42 , a second protrusion portion 43 , a clamp placement portion 44 , and a third protrusion portion 45 .

[0026] The cylindrical portion 41 is cylindrical and is arranged on the outside of the outer shell 21. The first protrusion 42 is arranged at one end of the cylindrical portion 41. The first protrusion 42 is arranged at the end of the cylindrical portion 41 on the side of the operation-side connecting portion 12. The first protrusion 42 protrudes radially outward from the cylindrical portion 41. In this embodiment, the first protrusion 42 is formed in a flange shape. The radial direction is a direction perpendicular to the central axis O of the cylindrical portion 41 and close to or away from the central axis. The first protrusion 42 is formed throughout the entire circumference of the central axis O of the cylindrical portion 41.

[0027] The second protrusion 43 is disposed at the other end of the cylindrical portion 41. The second protrusion 43 is disposed at the end of the cylindrical portion 41 on the transmission-side connecting portion 13 side. The second protrusion 43 is disposed opposite the first protrusion 42. The second protrusion 43 protrudes radially outward from the cylindrical portion 41. In this embodiment, the second protrusion 43 is formed in a flange shape.

[0028] The clamp member placement portion 44 is arranged on the side of the first protrusion portion 42 opposite the second protrusion portion 43. The clamp member placement portion 44 is cylindrical and is arranged coaxially with the cylindrical portion 41. The clamp member placement portion 44 is formed from the first protrusion portion 42 toward the operating-side connecting portion 12. The clamp member placement portion 44 is formed to have an outer diameter smaller than that of the cylindrical portion 41, but is not limited to this. The third protrusion portion 45 is arranged at the end of the clamp member placement portion 44 on the operating-side connecting portion 12 side. The third protrusion portion 45 protrudes radially outward from the clamp member placement portion 44. In this embodiment, the third protrusion portion 45 is formed in a flange shape.

[0029] (Fixing clamp 32)

[0030] The fixing clamp 32 secures the protector 31 to the outer housing 21. The fixing clamp 32 is attached to the outer periphery of the clamp placement portion 44 of the protector 31. The fixing clamp 32 is disposed on the side of the first protrusion 42 of the protector 31 opposite the second protrusion 43. The fixing clamp 32 is disposed between the first protrusion 42 and the third protrusion 45 of the protector 31.

[0031] The material of the fixing clamp 32 is not particularly limited, and is made of metal, for example. The fixing clamp 32 is, for example, a caulking ring. The protector 31 is fixed to the outer shell 21 by caulking with the fixing clamp 32 .

[0032] (Mounting clamp 33)

[0033] The mounting clamp 33 mounts the control cable 11 to the vehicle via the protector 31. The material of the mounting clamp 33 is not particularly limited, and is made of metal, for example. The mounting clamp 33 is formed by bending or stamping a plate-shaped member.

[0034] like Figure 2 As shown, the mounting clip 33 includes a protector-side mounting portion 51 (an example of a first mounting portion), a vehicle body-side mounting portion 52 (an example of a second mounting portion), and a connecting portion 53 .

[0035] like Figure 3 As shown in FIG. 5 , the protector side mounting portion 51 is cylindrical. The protector side mounting portion 51 is for the cylindrical portion 41 of the protector 31 to be inserted through. Figure 2 As shown, the protector-side mounting portion 51 is disposed between the first protrusion 42 and the second protrusion 43. The protector-side mounting portion 51 is configured to be slidable relative to the cylindrical portion 41. The protector-side mounting portion 51 is movable relative to the protector 31 between the first protrusion 42 and the second protrusion 43. The protector-side mounting portion 51 is disposed on the outer periphery of the cylindrical portion 41.

[0036] like Figure 2As shown, if the length between the first protrusion 42 and the second protrusion 43 along the central axis O of the protector 31 is L0 and the length of the protector-side mounting portion 51 along the central axis O is L1, L0>L1 is set.

[0037] like Figure 3 As shown, the inner diameter d1 of the protector-side mounting portion 51 is larger than the outer diameter d2 of the cylindrical portion 41. This creates a gap between the inner circumferential surface 51a of the protector-side mounting portion 51 and the outer circumferential surface 41a of the cylindrical portion 41, making it easier for the protector-side mounting portion 51 to slide relative to the protector 31.

[0038] like Figure 2 As shown, with the protector-side mounting portion 51 positioned centrally between the first protrusion 42 and the second protrusion 43, and with the length from the end of the protector-side mounting portion 51 on the operating-side connecting portion 12 side to the first protrusion 42 and the length from the end of the protector-side mounting portion 51 on the transmission-side connecting portion 13 side to the second protrusion 43 being L2, the values ​​of L1 and L2 are preferably set to 2×L2>L1. Furthermore, the values ​​of L1 and L2 are preferably set to L1>L2. L2 can also be set to, for example, approximately 15 mm. 2×L2 represents the length the control cable 11 can move when vibrating, and also includes the amount of adjustment required for the mounting position relative to the vehicle body frame portion 100.

[0039] The vehicle body side mounting portion 52 is formed in a plate shape. A through hole 52a is formed in the vehicle body side mounting portion 52. Bolts or the like are inserted into the through hole 52a, and the vehicle body side mounting portion 52 is fastened to the frame portion 100 of the vehicle body.

[0040] The connecting portion 53 connects the protector-side mounting portion 51 and the vehicle-side mounting portion 52. In this embodiment, the connecting portion 53 is plate-shaped, extends from the protector-side mounting portion 51 toward the transmission-side connecting portion 13, and connects to the vehicle-side mounting portion 52, but the present invention is not limited thereto.

[0041] (Installation action)

[0042] In this embodiment 1, when the control cable assembly 1 is installed on the vehicle body, Figure 2 As shown, the protector-side mounting portion 51 is arranged substantially at the center of the first protrusion portion 42 and the second protrusion portion 43 .

[0043] When the operator installs the control cable assembly 1 of the first embodiment on the vehicle body, Figure 2As shown, the protector-side mounting portion 51 is positioned approximately in the center between the first protrusion 42 and the second protrusion 43. In this position, the control cable assembly 1 is designed so that the vehicle-side mounting portion 52 is substantially aligned with the vehicle body frame 100. By positioning the vehicle-side mounting portion 52 on the vehicle body frame 100 and inserting bolts into the through-holes 52a, the vehicle-side mounting portion 52 can be secured to the vehicle body frame 100.

[0044] (Implementation Method 2)

[0045] In the second embodiment, the arrangement of the protector-side mounting portion 51 in the protector 31 when the control cable assembly 1 is mounted on the vehicle body is different.

[0046] Figure 4 It is a side view showing a part of the control cable assembly 1' according to the second embodiment. Figure 4 The control cable assembly 1 ′ shown is different from the control cable assembly 1 of the first embodiment in that two mounting structures 14 and 14 ′ are provided.

[0047] The mounting structure 14′ of this second embodiment has the same structure as the mounting structure 14, and includes a protector 31, a fixing clamp 32 (an example of a fixing component), and a mounting clamp 33 (an example of a mounting component). In this second embodiment, the fixing clamp 32 of the mounting structure 14 and the fixing clamp 32 of the mounting structure 14′ are arranged so as to face each other. The mounting structure 14′ is arranged on the C1 side of the mounting structure 14. In the mounting structure 14, the clamp placement portion 44 and the fixing clamp 32 are arranged at the C1 end of the protector 31. In the mounting structure 14′, the clamp placement portion 44 and the fixing clamp 32 are arranged at the C2 end of the protector 31.

[0048] In this embodiment 2, when the control cable assembly 1' is installed on the vehicle body, Figure 5 As shown, in the mounting structure 14, the protector-side mounting portion 51 abuts the first protrusion 42, while in the mounting structure 14', the protector-side mounting portion 51 abuts the first protrusion 42. In this state, the control cable assembly 1' is designed so that the vehicle body-side mounting portion 52 of the mounting structure 14 and the vehicle body frame portion 100 are substantially aligned, and the vehicle body-side mounting portion 52 of the mounting structure 14' and the vehicle body frame portion 100' are substantially aligned.

[0049] When installing the control cable assembly 1' on the vehicle body, the operator can abut the protector-side mounting portion 51 of the mounting structure 14 against the first protrusion 42, and the protector-side mounting portion 51 of the mounting structure 14' against the first protrusion 42, and then secure the protector-side mounting portions 51 of the mounting structures 14, 14' to the vehicle body frame portions 100, 100' using bolts or the like. Therefore, when the protector-side mounting portions 51 are attached to the vehicle body frame portions 100, 100' using bolts or the like, the protector-side mounting portion 51 abuts the first protrusion 42 in the mounting structure 14, and the protector-side mounting portion 51 abuts the first protrusion 42 in the mounting structure 14'.

[0050] Thus, when the control cable assembly 1 ′ is mounted on the vehicle body, the protector-side mounting portion 51 in the mounting structure 14 , 14 ′ abuts against the first protrusion 42 on the fixing clamp 32 side, so that the fixing clamp 32 can be used as a positioning reference.

[0051] (Features, etc.)

[0052] In the first and second embodiments, the length L0 between the first and second protrusions 42 and 43 is longer than the length L1 of the protector-side mounting portion 51, thereby facilitating position adjustment when mounted on the vehicle body. Furthermore, even if the vehicle body vibrates and the control cable 11 moves, the protector 31 and the control cable 11 can still move relative to the protector-side mounting portion 51, thereby preventing damage to the control cable 11.

[0053] The fixing clamp 32 is not located on both the first protrusion 42 and second protrusion 43 sides, but only on the first protrusion 42 side. Therefore, even if bending forces act on the protector 31 due to vehicle body vibration, the protector 31 can still follow these forces. Furthermore, because the protector 31 and the control cable 11 are not fixed using adhesive or the like, but are fixed at a single location on the end of the protector 31 using the fixing clamp 32, the protector 31 can follow these bending forces.

[0054] In the first and second embodiments, the inner diameter d1 of the protector-side mounting portion 51 is larger than the outer diameter d2 of the cylindrical portion 41. This creates a gap between the protector-side mounting portion 51 and the cylindrical portion 41, facilitating movement of the protector-side mounting portion 51 relative to the cylindrical portion 41. This improves the mobility of the protector 31 during position adjustment and movement of the control cable 11.

[0055] In the first and second embodiments, by setting the movable distance of the protector-side mounting portion 51 to 2×L2>L1, the position adjustment amount and the movement amount of the control cable 11 can be ensured.

[0056] In this embodiment 1, when the protector side mounting portion 51 is positioned approximately in the center of the first protrusion portion 42 and the second protrusion portion 43 and the mounting structure 14 is fixed to the vehicle body, if L2 is too long, positioning is difficult, but by setting L1>L2, the operator can easily perform positioning.

[0057] In the second embodiment described above, the protector-side mounting portion 51 is arranged so that it abuts the first protrusion 42 on the side where the fixing clamp 32 is located while the mounting clamp 33 is fixed to the vehicle body. This allows the fixing clamp 32 on the first protrusion 42 side to be used as a reference for positioning when securing the mounting clamp 33 to the vehicle body. This facilitates attaching the control cable assembly 1' to the object. Furthermore, even if the protector-side mounting portion 51 moves toward the first protrusion 42 due to vibration or other factors, the fixing clamp 32 suppresses deflection of the first protrusion 42, preventing the protector-side mounting portion 51 from falling off the protector 31.

[0058] In the first and second embodiments, the control cable is used as a transmission shift cable. A transmission shift cable with a large diameter and a large operating load generates large vibrations, but the use of the mounting structures 14 and 14' of the first and second embodiments effectively prevents damage.

[0059] (Other Implementation Methods)

[0060] As mentioned above, although one embodiment of the present disclosure has been described, the present disclosure is not limited to the above embodiment, and various changes can be made without departing from the scope of the present disclosure.

[0061] (A)

[0062] In the above-mentioned first and second embodiments, the control cable 11 is used as a shift cable of a transmission, but the invention is not limited thereto and may be used as a cable for parking, for example.

[0063] (B)

[0064] As an example of a long component that can be mounted using the mounting structures 14 and 14' of the first and second embodiments, a control cable used in a vehicle is cited. However, the present invention is not limited to this embodiment and can also be applied to a structure for mounting a simple long component on an object. Furthermore, the object to which the long component can be mounted is not limited to a vehicle.

[0065] (C)

[0066] In the second embodiment described above, when the protector-side mounting portion 51 is attached to the vehicle body frame portion 100 or 100', the protector-side mounting portion 51 abuts the first protrusion 42 in the mounting structure 14 and the first protrusion 42 in the mounting structure 14'. However, the protector-side mounting portion 51 does not need to abut the first protrusion 42, and the protector-side mounting portion 51 may be positioned closer to the first protrusion 42 than the second protrusion 43. In short, any requirement exists as long as the fixing clamp 32 can be used for positioning when the control cable assembly 1' is attached to the vehicle body. Positioning the protector-side mounting portion 51 closer to the first protrusion 42 than the second protrusion 43 means that at least the distance from the protector-side mounting portion 51 to the first protrusion 42 is shorter than the distance from the protector-side mounting portion 51 to the second protrusion 43.

[0067] (D)

[0068] The control cable assembly 1 in the first embodiment is provided with one mounting structure 14 , and the control cable assembly 1 ′ in the second embodiment is provided with two mounting structures 14 , 14 ′, but the present invention is not limited thereto. The number of mounting structures may be appropriately changed according to the length of the control cable and the wiring path.

[0069] (E)

[0070] In the first embodiment described above, the clip placement portion 44 and the fixing clip 32 are placed at the end portion on the C1 direction side of the protector 31 , but may be placed at the end portion on the C2 direction side.

[0071] (F)

[0072] In the second embodiment described above, the clamp placement portion 44 and the fixing clamp 32 are arranged facing each other in the mounting structures 14 and 14'. However, the present invention is not limited thereto. In the mounting structure 14, the clamp placement portion 44 and the fixing clamp 32 may be arranged at the end of the protector 31 on the C1 side, while in the mounting structure 14', the clamp placement portion 44 and the fixing clamp 32 may be arranged at the end of the protector 31 on the C2 side. Furthermore, in both the mounting structures 14 and 14', the clamp placement portion 44 and the fixing clamp 32 may be arranged at either the end of the protector 31 on the C1 side or the end on the C2 side.
