[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for holding a control cable used for transmitting the movement of an operating lever to a damper for adjusting the air flow in an air conditioner of an automobile, for example.

[0002]

2. Description of the Related Art In general, a control cable used for such a purpose is composed of an outer tube made of a synthetic resin or the like, and a cable main body movably running in the longitudinal direction in the outer tube. FIG.
FIG. 2 is an exploded perspective view showing the control cable holding structure. In the figure, reference numeral 1 denotes a control cable composed of a cable main body 1a and an outer tube 1b;
Is a clamp, and 3 is a fixing member. The clamp 2 is formed of an elastic metal material,
It has a U-shaped first holding portion 2a for holding b, and a U-shaped second holding portion 2b for mounting on the fixing member 3.
The first holding portion 2a and the second holding portion 2b are arranged such that the space between the opposing plate-shaped portions is in the free state, and the outer tube 1
The outer tube 1b is formed so as to be smaller than the outer diameter of the outer tube 1b and the thickness of the fixing member 3 at the time of mounting.
Are fixed to the fixing member 3 by the second holding portion 2b.

[0003]

In this holding structure, since the holding is performed only by the elasticity of the clamp 2, the second holding portion 2b is detached from the fixing member 3, or the cable 1 is moved to the right in FIG. It may come off from the 1 holding part 2a.
If such a situation occurs, the operation of the cable main body 1a may be hindered, and there is a possibility that an accurate movement of a driven object such as a damper of the air conditioner may not be obtained.

[0004] Therefore, a technical problem to be solved by the present invention is to provide a control cable holding structure capable of reliably holding the position of the outer tube and ensuring accurate movement of the driven object.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned technical problems, a control cable holding structure according to the present invention is configured as follows. That is, the clamp and the fixing member each have one of a convex portion and a concave portion that allow the engagement of each other by elastic deformation of the clamp when the clamp is mounted on the fixing member, while restricting the clamp from dropping off after the mounting. Is formed. In addition, at least one of the clamp and the fixing member is, for example, bites into the outer tube, engages with a groove formed on the outer peripheral surface of the outer tube, and is located on the inner diameter side with respect to the outer peripheral surface of the outer tube. A first holding means for preventing the outer tube from moving in the longitudinal direction is provided. The clamp and the fixing member include, for example, a second holding unit such as a pressing surface that covers the entire circumference of the outer cable in combination with each other and thereby restricts displacement in the radial direction.

[0006]

In the above construction, the clamp is held by the fixing member by engaging the convex means with the concave means while elastically deforming the clamp, so that the control cable can be held therebetween. When the clamp is attached in this manner, the first holding means is located on the inner diameter side with respect to the outer peripheral surface of the outer tube, and its movement in the longitudinal direction is restricted. In this state, the radial displacement of the outer cable is restricted by the second holding means.

Therefore, according to the above configuration, since the position of the control cable can be reliably held at the attached position, accurate movement of the driven object such as the damper of the air conditioner can be ensured.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a control cable holding structure according to an embodiment of the present invention shown in FIGS. 1 to 5 will be described in detail.

First, a holding structure according to a first embodiment will be described with reference to an exploded perspective view shown in FIG. In the figure, 11 is a control cable, 12 is a clamp,
13 is a fixing member. The control cable 11
As in the conventional case, it is composed of a cable main body 11a and an outer tube 11b. The clamp 12 is formed in a substantially U-shaped cross section from two opposing walls 12a sandwiching the cable 11 and a connecting portion 12b (second holding means) connecting the opposing walls 12a. A U-shaped notch is formed at the center of both opposing walls 12a, and a portion surrounded by the notch is turned outward to form a claw 12c (projecting means).
Further, the connecting portion 12b has projecting pieces on both outer sides, and the projecting pieces are bent toward the cable 11 side to form claws 12d (first holding means).
Are formed. When the clamp 12 is inserted into the cable 11 from the side and the claws 12d bite into the outer tube 11b, and the inner surface of the connecting portion 12b becomes along the outer peripheral surface of the outer tube 11b, the tip of the opposing wall 12a is 11 are formed so as to protrude.

On both sides of the bottom surface 13b (second holding means) of the recess 13a, slits 13c for receiving the tip of the opposing wall 12a of the clamp 12 are formed, and both sides 13d of the recess 13a (second holding means) are provided with the clamps 12c. Groove 13e to receive the claw 12c
(Recess means) is formed in connection with the slit 13c. An inclined surface 13f for guiding the claw 12c when the cable 11 is attached is formed at the upper end of the both side walls 13d.

In the present embodiment, first, after the clamp 12 is sandwiched between the cables 11, the cable 11 is inserted into the recess 13a of the fixing member 13 together with the clamp 12. At this time, while the claw 12c is guided by the inclined surface 13f of the fixing member 13 and bends inward, the tip of the opposing wall 12a is
The claw 12c engages with the groove 13e when it enters the inside 3c, and the mounting is completed.

In the mounted state, the movement of the cable 11 in the longitudinal direction is prevented by the claw 12d biting into the outer tube 11b and the tip of the opposing wall 12a being inserted into the slit 13c. Further, the movement in the radial direction is prevented by the side wall 13d of the concave portion 13a, the connecting portion 12b of the bottom surface 13b and the clamp 12 surrounding the entire circumference of the outer tube 11b. As described above, in the above embodiment, since the position of the clamp is regulated by the convex and concave means and the cable 11 is held by each holding means, the position of the cable 11 can be reliably held.
