Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a holding device for a remote control cable used for interlocking and connecting the carburetor and accelerator pedal of an internal combustion engine in a vehicle, for example.

[Prior Art] As shown in FIG. 1, in a cab-over type truck, etc., when the driver's seat accelerator pedal 2 is depressed, an arm 4 is rotated about a support shaft 3, and a lever 6 is activated via a link 5. It is rotated about the support shaft 15, the inner cable 7a of the remote control cable is pulled, and the required members 16 of the carburetor are pulled together to adjust the rotational speed of the internal combustion engine. The remote control cable is connected to the inner cable 7 to the outer tube 7.
One end of this outer tube 7 is fixed to the floor plate 12 adjacent to the lever 6, while the other end passes through a hole 9 in the wall plate 13 of the engine hood that is integrated with the floor plate 12, and is attached to the internal combustion engine side. It is fixed to a bracket 10 attached to.

In the case of cab-over type vehicles where the internal combustion engine is located under the floor, it is difficult to curve the middle part of the remote control cable, and if it is unnecessarily slack, it may interfere with other components. Cheap.
For this reason, the outer tube 7 of the remote control cable is supported at one end by a clip 8 on the underside of the floor plate 12, and the portion that passes through the wall plate 13 of the engine hood is fitted with a grommet 14 so that there is not much slack.
is maintained by

However, if the outer tube 7 is not allowed to have much slack due to curvature, relative vibration between the vehicle body and the internal combustion engine will cause relative displacement between the outer tube 7 and the grommet 14, which may cause the grommet 14 to wear and break.

That is, as shown in FIG. 2, the conventional general grommet 14 has a flange 23 integrally formed on one end side of a cylindrical part 21 that is fitted onto the outer tube 7, and a flange 23 formed on the outer peripheral surface of the flange 23. The annular groove 24 is engaged with the hole 9 in the wall plate 13 of the engine hood. When axial vibration or unreasonable force is applied to the outer tube 7, the cylindrical portion 21 and the flange 23
The connecting portion between the inner cable 7a and the inner cable 7a will be damaged, and the outer tube 7 will come into direct contact with the edge of the hole 9 in the wall plate 13 and be worn out, and eventually the inner cable 7a will also be damaged.

On the other hand, as shown in FIGS. 3 and 4, the flange 28 that is locked to the wall plate 13 and the cylindrical portion 27 that supports the outer tube 7 are integrally constructed,
Bolts 26 and nuts 2 are attached to the plate surface of the flange wall plate 13.
Some items are fixed by 9. In this case, the outer tube 7 diagonally passes through the hole 9 in the wall plate 13.
In order to support the cylindrical portion 27, the cylindrical portion 27 is integrally constructed at an angle with respect to the flange 28, and this flange 28 is overlapped with the wall plate 13, and three bolts 26
and is fastened by a nut 29. A known tightening clip 25 attached to the tip of the cylindrical portion 27 allows
Relative axial movement between the cylindrical portion 27 and the outer tube 7 is suppressed. However, in this configuration, in addition to the hole 9 for attaching the conventional grommet, there is also a bolt 26.
A hole is provided through which the nut 29 is inserted, and a nut 29 is provided in the wall plate 13.
This is not desirable in terms of cost since extra processing such as welding and fixing is required.

Furthermore, as disclosed in Japanese Utility Model Publication No. 57-56919, a holder for fixing the terminal of a remote control cable to a wall plate is also known, but this is limited to the terminal of the remote control cable, and the intermediate part Not suitable for holding. This is because when the thread groove provided on the conical part of this holder is screwed into the hole in the wall plate, the holder is fixed so that it does not move in the axial direction, but the outer tube of the remote control cable is simply inserted through the holder. However, the holder does not have the function of tightly holding the outer tube by contracting the holder radially inward when the holder is screwed.

[Problems to be solved by the invention] In view of the above problems, the object of the invention is to provide a remote control cable holding device in which the outer tube is tightly supported by a holding body in a conventional grommet mounting hole without requiring any extra processing of the wall panel.

[Means for Solving the Problem] In order to achieve the above object, the structure of the present invention is such that a flange that abuts against a wall plate is provided in the center of a cylindrical body through which the outer tube is inserted and supported, and a conical part is provided on one end side. The conical part has a screw groove that screws into the hole in the wall plate,
A plurality of axial grooves are provided at intervals in the circumferential direction.

[Function] By screwing the threaded groove 31 of the conical part 30 on one end of the cylinder having the split groove 32 into the hole 9 of the wall plate 13, the cylinder is deflated, so that the outer tube 7 is firmly attached to the cylinder. At the same time, the holding body A is connected to the wall plate 13.
It is supported without play in the hole 9.

[Embodiment of the invention] As shown in FIGS. 5 and 6, the holder A that supports the outer tube 7 through the hole 9 of the wall plate 13 is preferably made of a hard material such as synthetic resin or metal,
As a whole, it forms a cylindrical body into which the outer tube 7 is fitted. A flange 34 that abuts one surface of the wall plate 13 is provided at the center of the cylindrical body, and a pair of ribs or knobs 33 that extend radially outward from the cylindrical body protrude from the flange 34 on the proximal end side.

A conical portion 30 having a tapered outer peripheral surface is formed on the distal end side of the flange 34 . A thread groove 31 is formed in this conical portion 30, and a plurality of axial grooves 32 are provided at intervals in the circumferential direction.

As shown in FIG. 6, preferably, a plurality of axial protrusions 35 are disposed at intervals in the circumferential direction on the inner peripheral surface of the cylindrical body through which the outer tube 7 is inserted.

In the above structure, when the outer tube 7 is inserted into the holder A and the conical part 30 of the holder A is screwed into the hole 9 of the wall plate 13, the conical part 30 divided by the grooves 32 is gradually compressed. , the inner diameter of the conical portion 30 is reduced. Therefore, the protrusion 35
The outer tube 7 is strongly tightened to prevent it from moving in the axial direction.

The holder A is fixed to the wall plate 13 by engagement between the thread groove 31 and the edge of the hole 9 when the flange 34 is pressed against one surface of the wall plate 13.

[Effects of the invention] As described above, the present invention provides a flange that contacts the wall plate at the center of the cylindrical body through which the outer tube is inserted and supports, and a conical part at one end, and the conical part is screwed into the hole in the wall plate. Since a mating thread groove and a plurality of axial grooves spaced apart in the circumferential direction are provided, the holder is coupled to the wall plate by simply screwing the holder into the hole in the wall plate, and at the same time, the holder is connected to the wall plate. The outer tubes are joined together without any play.

Unlike the conventional example, it can be installed without making extra holes in the wall plate, making the work extremely simple.

Compared to conventional grommets, the remote control cable is stably and tightly supported by the wall plate against relative displacement between the vehicle body and the internal combustion engine, thereby avoiding damage to the wall plate penetrating support portion of the remote control cable.
