2. Description of the Related Art Conventionally, a diesel engine is provided with a control unit for controlling the diesel engine, and a control cable for operating the control unit is connected. FIG. 6 is a diagram showing an example of such a control cable.
1 is provided with a control cable 62 for externally controlling the control unit. The control cable 62 has flexibility, and as shown in FIG. 7, a cable 64 for transmitting an operating force is inserted into a long casing pipe 63 so as to be movable in the extending direction. The casing pipe 63
Between the inner peripheral wall 63 a and the cable 64.
An extra space 65 that allows the movement of the vehicle 4 is secured.
Further, one end of the casing pipe 63 is fixed to a control unit of the engine 61, and the other end is
A hollow mounting bracket 66 fixed to an unillustrated instrument panel is provided. An end of the cable 64 protrudes from the mounting bracket 66, and an operation knob 67 is provided. Although not shown, the other end of the cable 64 extends from one end of the casing pipe 63 and is connected to a fuel injection amount adjusting lever of a control unit provided in the diesel engine 61. I have. Therefore, by pulling (or pushing) the operation knob 67, the operation force is transmitted to the lever and the fuel injection amount can be changed.

[0003]

However, in such a conventional control cable 62, when the vibration of the control cable 62 is transmitted to the cable 64 during the operation of the engine 61, the cable 64 becomes free from the extra space in the casing pipe 63. It vibrates in the space 65 and periodically collides with the inner peripheral wall 63a of the casing pipe 63. Along with this, a low-pitched sound generally called chattering sound is generated while the control cable 62 is extending, and as a result, there is a problem that the quality of the automobile is deteriorated.

[0004] The present invention has been made in view of such a conventional problem, and has as its object to provide a cable clip that prevents generation of low-pitched sound from a control cable when an engine is operating.

[0005]

According to the present invention, a cable for transmitting an operating force extends in a casing pipe having one end fixed to a control unit of a diesel engine. The flexible control cable, which is movably inserted into the control cable, is mounted in the middle of the extension of the flexible control cable, is connected in order in the extending direction of the control cable, and a space for inserting the control cable therebetween is secured. A first contact portion, a second contact portion, and a third contact portion. The second contact portion contacts the control cable from one side, while the first contact portion contacts the control cable. A cable clip in which the contact portion and the third contact portion contact the control cable from the other side.

[0006]

In the above construction, the control cable with the cable clip attached is bent abruptly by the first to third contact portions in the middle of the extension. On the other hand, at the bent portion of the cable clip, the cable inserted inside the casing pipe comes into contact with the inner peripheral wall of the casing pipe. Therefore, at the attachment point of the cable clip, due to the vibration transmitted from the engine,
The cable is prevented from vibrating in the casing pipe and colliding periodically with the inner peripheral wall thereof.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a use state of a cable clip 1 according to the present invention.
It is attached to a control cable 51 for controlling the control unit, one end of which is fixed to the control unit of the diesel engine.

The control cable 51 has the same flexibility as the control unit control cable described in the conventional example. As shown in FIGS. Has a structure in which a cable 53 for transmitting an operating force is movably inserted in the extending direction, so that the cable 53 can be moved between the inner peripheral wall 52a of the casing pipe 52 and the cable 53. A margin space 54 is formed. The outer circumference of the casing pipe 52 is covered with a foam protector 55 over the entire area in the extending direction. In addition, control cable 5
1 is fixed to a diesel engine (not shown), and the other end of the control cable 51 is connected to the other end of the casing pipe 52 from the cable 5.
3 extends, and at the end thereof, a mounting bracket 56 for mounting the cable 53 to an instrument panel (not shown) or the like is provided.

On the other hand, the cable clip 1 is made of a plate-like member, and has a meandering shape like a crank.
Each of the cable clips 1 has a length that traverses the cable clip 1, and includes a first contact portion 1 a and a second contact portion 1 a that are sequentially arranged in the extending direction of the control cable 51.
, A third contact portion 1c, and a fourth contact portion 1d. These first to fourth contact portions 1a to 1d
On the one end side or the other end side, the first connection part 1e, the second connection part 1f, and the third connection part 1g alternately located on both sides of the control cable 51, thereby mutually adjoining one another. Are linked. Also, the first to first
Between each of the fourth contact portions 1a to 1d, the insertion spaces 2, 3, and 4 for the control cable 51 are secured, and the first contact portion 1a and the third contact portion 1c are separated. The second contact portion 1b and the fourth contact portion 1d are in contact with the control cable 51 from one side (upper side in FIG. 2) and the other side (lower side in FIG. 2). .

That is, the control cable 51 is
The cable clips 1 are inserted in the insertion spaces 2, 3, and 4 while meandering around the first to fourth contact portions 1a to 1d, while the flexible control cable 51 extends. It is locked to the control cable 51 by the desired force.

In this embodiment having the above configuration,
The extension of the control cable 51 to which the cable clip 1 is attached is positively bent by the first to fourth contact portions 1a to 1d. For this reason, as shown in FIG. 3, at the bent portion of the cable clip 51, the cable 53 inserted into the inside of the casing pipe 52 comes into contact with the inner peripheral wall 52 a of the casing pipe 52. Therefore, at the attachment point of the cable clip 1, the cable 53 vibrates in the extra space 54 in the casing pipe 52 due to the vibration transmitted from the engine, and periodically collides with the inner peripheral wall 52 a of the casing pipe 52. Is prevented. Therefore, by appropriately attaching the cable clip 1 in the middle of the extension of the control cable 51, it is possible to prevent the generation of low-pitched sound in the control cable 51 when the engine is operating. As a result, a decrease in the quality of the automobile is prevented.

In this embodiment, the cable clip 1 has four contact portions. However, the fourth contact portion 1d (or the first contact portion 1a) may be omitted. It is possible. That is, as shown in FIG. 4, the cable clip 11 may include only the first to third contact portions 1a to 1c and the first and second connection portions 1e and 1f for connecting the first to third contact portions 1a to 1c. Even with such a configuration,
The effects described above can be obtained. Although not shown, the same effect can be obtained even if the number of the contact portions is increased as necessary. That is, in the cable clip of the present invention, it is sufficient that there are three or more contact portions connected to each other.

In the above-described embodiment, three or four abutting portions adjacent to each other are alternately provided at one end and the other end thereof at one end and the other end with the control cable 51 interposed therebetween. Are connected via the connecting portion located at the position, i.e., those having a meandering shape in a crank shape, but are not limited to this, and each of the adjacent abutting contacts like the cable clip 21 shown in FIG. All of the portions 1a to 1c may be connected by connecting portions 1e and 1f located only on one end side. Even with such a configuration, the above-described effects can be obtained. In this case, as shown in the figure, the other end of each of the contact portions 1a to 1c that is not connected protrudes toward the other end of the other adjacent contact portions 1a to 1c. It is desirable to provide the locking projections 22, 22, 22 that protrude in the extending direction of the cable 51. According to such a configuration, even if the above-described force for extending the control cable 51 decreases with time, the locking projection 2
2, 22, 22 can prevent the cable clip 21 from detaching from the control cable 51.

[0014]

As described above, in the cable clip according to the present invention, the control cable is bent at its attachment point in the middle of the extension so as to cause the vibration transmitted from the engine. Further, the configuration is such that the cable is prevented from periodically colliding with the inner peripheral wall of the casing pipe. Therefore, by appropriately attaching the cable clip of the present invention in the middle of the extension of the control cable, it is possible to prevent the generation of low-pitched sound from the control cable when the engine is running. As a result, a decrease in the quality of the automobile is prevented.
