Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a control cable holding device for holding an end of a covering portion in a hole of a panel or the like in a control cable, for example.

(Prior Art) In a control cable, for example, an automobile throttle control cable 1 connects an engine 2 and an accelerator pedal 3 as shown in FIG. 5, and is arranged so as to penetrate a dash panel 4. There is. The dash panel 4 is a panel that separates the engine room and the passenger compartment of the automobile from each other to prevent rainwater, engine noise, hot air, and the like from entering the passenger compartment. Therefore, the control cable holding device 5 used for the dash panel 4 is
It is required to prevent rainwater, engine noise, and hot air from entering the vehicle interior.

In a conventional control cable holding device, for example, as shown in FIG. 6, a casing cap 7 is fixed to an end portion of an outer cable 6, and a tab 8 of the casing cap 7 is attached to an edge of a hole of a dash panel via a packing 9. The control cable 1 was held by being caught.

In addition, as shown in FIG. 7, a casing cap 7 is fixed to the end portion of the outer cable 6, and the dash panel 4 is sandwiched between the casing cap 7 and the retainer 10 via the anti-vibration rubber 11, and the bolt 12 is attached. Control cable 1 by crimping and clamping with nut 13
Is to hold.

(Problems to be Solved by the Invention) In the conventional example shown in FIG. 6, the claw 8 of the casing cap 7 is in direct contact with the dash panel 4, so that the vibration of the outer cable 6 causes the casing cap to vibrate. 7 is transmitted to the dash panel 4 to generate noise in the passenger compartment. Further, there is a problem that the claw 8 cannot obtain a sufficient holding force, and due to the poor sealing of the packing 9, a sufficient effect cannot be obtained for preventing rainwater, engine noise, and the like from entering the vehicle interior. or,
It is difficult to remove from the dash panel, and there is a problem that the claw may break.

On the other hand, in the case shown in FIG. 7, the contact portion with the dash panel 4 is entirely via the anti-vibration rubber 11, and the holding force by the bolt nut is sufficient, so the outer cable 6
Although it is effective in preventing the vibration of the vehicle and the entry of rainwater, engine noise, etc. into the vehicle interior, there are problems in the following points. That is, the dash panel 4 needs to have a hole through which the bolt 12 penetrates, and the bolt 12 can be mounted from the engine room side or the vehicle compartment side.
Moreover, since the nut is located on the back side, there is a drawback that workability is poor because work from both sides of the engine room and vehicle interior is required, and a tool for tightening the bolt nut is required.

In view of the above points, an object of the present invention is to provide a control cable holding device that can be easily assembled without using a tool, and that rainwater, vibration, noise, etc. are unlikely to enter.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a grommet 17 made of an elastic member having a collar 18 at one end of a cylinder 19 having an inner surface formed with a tapered hole 20. Then, the casing cap 7 having the support surface 28 of the grommet 17 at one end and the gripping surface 19 at the other end and having a through hole communicating with the tapered hole 20 of the grommet 17 is provided. Further, a knob 15 that is in contact with the knob contact surface 29 of the casing cap 7 is integrally provided at one end of the cylinder 30, and a threaded portion 16 is formed at the outer peripheral portion of the other end of the cylinder 30 to be inserted into the through hole of the casing cap 7. The sleeve 14 is provided, and the nut 21 located inside the tapered hole 20 of the grommet 17 and screwed into the threaded portion 16 of the sleeve 14 is provided.

(Operation) With this configuration, the grommet 17 is inserted into the hole of the dash panel 4, the knob 15 of the sleeve 14 is rotated, and the nut 21 is tightened, so that the nut 21 presses the inner surface of the tapered hole 20 of the grommet 17. While moving, grommet 17
The cylinder 19 of is deformed while being caught. Then, the grommet 17 is formed by the collar 18 and the deformed cylinder 19 into the dash panel 4.
Hold them tightly together.

(Example) Hereinafter, one example of the present invention will be described in detail.

In FIG. 1, 7 is a casing cap having a through hole. As shown in FIG. 4, the casing cap 7 is formed with an insertion cylindrical portion 27, a grommet support surface 28, and a knob contact surface 29. The sleeve 14 is a pipe-shaped member having a knob 15 at one end of a cylinder 30. 16 is a screw part. A grommet 17 has a collar 18 at one end of a cylinder 19 having a tapered hole 20 on the inner surface, and is made of an elastic body such as rubber. In FIG. 4, reference numeral 26 is a grommet support surface. Reference numeral 21 is a nut screwed into the threaded portion 16 of the sleeve 14. The nut 21 has a size such that it can be pressed against the inner surface of the tapered hole 20 of the grommet 17. The pipe 22 is for holding the control cable 1 by fixing one end of the outer casing 6 to the flange 23 at one end. A cable 25 connected to the control cable is inserted inside the pipe 22. pipe
As shown in the figure, 22 is inserted and penetrated into the sleeve 14, and the end portion on the opposite side of the flange 23 is caulked or the like.
24 is formed and is rotatably retained on the sleeve 14 by the flanges 23, 24.

The operation of this embodiment configured as described above will be described.

First, the assembly will be described. The control cable holding device 5 is attached to one end of the outer cable 6 as follows. In FIG. 4, the cable 25 and the pipe 22 are inserted into the sleeve 14. Next, insert the casing cap 7 and the grommet 17 into the sleeve 14 and nut.
21 is screwed onto the screw portion 16. Then, the tip of the pipe 22 is caulked to form the flange 24 (Fig. 1).

As a result, the insertion cylindrical portion 27 of the casing cap 7
Is inserted into the grommet 17, and the grommet side support surface 28 and the grommet 17 are in close contact with each other, and are integrally joined by the flanges 23 and 24 as shown in FIG. And the third
As shown in the figure, the control cable holding device 5 is attached to the tip of the outer cable 6.

In this way, the control cable holding device is attached to the tip of the outer cable 6 in advance. Then, the cylinder 19 of the grommet 17 is inserted into, for example, the hole of the dash panel 4. While holding the casing cap 7, the knob 15 of the sleeve 14 is rotated. Due to this rotation, the rotation of the nut 21 is restricted by contact with the taper hole 20, and the nut 21 moves to the left toward the paper surface of the drawing while the taper hole of the grommet 17 is being moved.
The inner surface (tapered surface) of 20 is pressed, and the cylinder 19 of grommet 17
Expand the outer diameter of as shown in Fig. 2. Then, as shown in FIG. 2, the grommet 17 is deformed, and the dash panel 4 is tightly clamped by the deformed cylinder 19 of the grommet 17 and the brim 18 by the compression of the nut 21.

Also, by rotating the knob 15 of the sleeve 14 in the reverse direction,
The grommet 17 is restored to its original shape and can be removed.

(Effect of the Invention) As described in detail above, according to the present invention, the inner surface is provided with the grommet, the flange at one end, and the pipe member having the threaded portion on the outer circumference of the other end and the nut screwed to the threaded portion. The control cable can be held by the deformation of the grommet due to the tightening pressure of the screw portion and the nut.

In this way, the grommet is deformed by the compression of the screw portion and the nut to clamp the dash panel in close contact, so that a sufficient holding force can be obtained and rainwater and noise can be prevented from entering.

Further, since the control cable is held via the grommet, its vibration is difficult to be transmitted, and the outer cable is rotatable with respect to the control cable holding device, so that it does not twist even when the knob is turned during installation. .

Furthermore, due to the wedge effect, it is not necessary to hold the nut, so assembly work can be done on only one side of the panel, there is no directionality, no tools are required, and it can be freely attached and removed and can be reused. Therefore, it has an excellent effect that workability is good.
