Description

[Detailed description of the invention] Purpose of the invention (industrial application field) The present invention is a cable fixing clip for fixing cables or cords, such as air mix doors and template levers of automobile air conditioners. This invention relates to a cable mount for fixing a control cable, which connects a lever for opening and closing doors of various ducts and a mode switching lever, to interlock each door with the control lever, to an automobile air conditioner or a controller.

(Prior Art) An example of a device in which this type of cable attachment is used is an air conditioner for an automobile. As shown in FIG. 1, this automotive air conditioner consists of an intake unit 1, a cooler unit 2, and a heater unit 3. Each unit 1, 2, and 3 has various doors 4, which need to be opened and closed. The various doors 4, 5, 6, and 7 are controlled to open and close using the instrument panel's template lever 8, mode switching lever 9, and intake door switching lever (not shown). Therefore, air adjusted to a desired temperature is blown out from a desired outlet.

In this automotive air conditioner, the cables that connect the various doors 4, 5, 6, 7 and the control levers 8, 9, for example the cable 10 that connects the template lever and the mixer door 5, include an inner cable 11 and a cable that connects the control levers 8, 9. A cable outer 12 is used which protects the cable and serves as a guide for determining the stroke. Usually, the cable outer 12 is molded from synthetic resin because it requires flexibility and mechanical strength, and weight reduction must also be considered. A clip 14 whose both ends are fixed to the controller board 13 and an appropriate fixing member 15 near the air mix door 5
It is fixed by a clip 16 attached to it so that it does not move easily.

Furthermore, as shown in FIG. 7, a control wire fixing device has been proposed (Utility Model Application No. 50-143249) in which a cable outer can be attached swingably in a horizontal plane. This fixing device is a cable outer 102 of the control wire 101.
A bracket 106 having a hole 105 for slidingly fitting with a fulcrum shaft 104 provided on the base 103 side of the device is fixed by caulking, and the hole 105 of this bracket 106 and the support shaft 104 are rotatably fitted and attached.

(Problems to be solved by the invention) However, the cable fixing device shown in Fig. 1
Since the clips 14 and 16 simply press and fix the cable outer 12 portion of the cable 10 to the board 13 etc., when the inner cable 11 is pulled by the control lever 8, the swinging of the control lever 8 The resulting displacement perpendicular to the direction of traction can cause the cable 10 to become detached from the clip 14. In order to prevent this, the force of the clips 14 and 16 is increased and the cable outer 1
Even if 2 is firmly fixed, the inner cable 1
1 will be bent and fatigued, and the cable outer 12 itself will be damaged by rubbing between the clips 14 and 16, which cannot be overcome.

Furthermore, the fixing device shown in FIG.
It is possible to swing in the horizontal plane parallel to the base 103, but the movement in other planes, especially in the plane perpendicular to the base 103, is fixed. Even if the cable outer is bent or displaced, the inner cable will simply tilt relative to the outer cable, requiring a large amount of force to operate the lever, which will not only impede smooth operation, but also cause fatigue of the cable outer, potentially shortening its lifespan. There is.

SUMMARY OF THE INVENTION An object of the present invention is to provide a fixing device for a cable that can be fixed so that the cable can be swung both horizontally and vertically in accordance with the movement of a control lever.

Structure of the Invention (Means for Solving Problems) In order to achieve the above object, the control cable attachment of the present invention has a control cable whose axis center is attached to the cable outer of the control cable that connects the controlled member and the control lever. An engaging piece is formed of a substrate having a protrusion that protrudes in a direction perpendicular to the cable outer side and extends in the same orthogonal direction on a surface on the cable outer side, and a connecting portion that connects the substrate and the cable outer. The member has, on the side of the member in which the outer is to be housed, a ceiling portion in which an opening into which the engaging piece can be fitted is bored when the cable to which the engaging piece is fixed is rotated by 90 degrees with respect to when in use. It consists of a hollow body protruding from the surface, and in use, a fixed engagement member is provided to restrict the detachment of the engagement piece, and by fitting the engagement piece and the fixed engagement member, the cable outer It is installed so that it can swing horizontally and vertically. As a result, the cable outer can swing in both the horizontal and vertical directions due to the pivoting movement of the engagement piece and the rolling movement of the protruding portion.

(Example) Hereinafter, the configuration of the present invention will be described in detail based on an example shown in the drawings. This figure shows a first embodiment of the fixture according to the present invention.

As shown in FIG. 2, a cable (also called a push-pull wire) 32 that connects the air mix door 5 of the air conditioner body (FIG. 1) and the control lever 8 of the controller is connected to an inner cable 33 and a cable outer 34. Consists of. The control cable attachment of the present invention is
An engagement piece 37 provided on the cable outer 34;
Fixed engagement members 38 provided on the substrate 13 are fitted together. An engagement piece 37 is formed at the end of the cable outer 34 so as to extend downward from the cable outer 34 . The engagement piece 37 includes a connecting portion 35 fixed to the cable outer 34 and a rectangular base 3 fixed below the connecting portion 35 and protruding in a direction perpendicular to the cable outer axis.
It consists of 6. A protrusion 39 having a semicircular cross section is formed in the center of the upper surface of the base seat 36 in the longitudinal direction.

This engagement piece 37 is connected to the cable outer 3
4 is fitted into the fixing engagement member 38 provided on the board 13 of the controller to fix the cable 32 to the board 13, and is provided integrally with the cable outer 34. . In this embodiment, this engagement piece 37 is
When the cable outer 34 is molded, it is integrally molded from the same synthetic resin material. Therefore, the installation process can be skipped, and manufacturing costs can be kept low.

Of course, the invention is not limited to this embodiment, and it is also possible to form the engaging piece 37 separately and integrate it with the cable outer 34 by adhesive. or,
Although not shown, the engagement piece 37 is connected to its base 36.
The base 36 is made of synthetic resin, the connecting part 35 is made of a metal spring material for use as a clip, and the connecting part 35 is connected to the base 36 by caulking, etc. At the same time, the engaging piece 37 and the cable outer 34 can be integrated by press-fitting the cable outer 34 into the clip connecting part 35.

On the other hand, the fixed engagement member 38 is for fitting the engagement piece 37 to the equipment side base, for example, the board 13 of the controller, and is integrally formed by embossing the board 13 (see FIG. 3) and is attached to the board 13. It is formed on 13. As shown in FIG. 3, this fixed engagement member 38 bulges the board 21 upward in a substantially cylindrical shape to form a space 40, and its top plate portion 31 forms a ridge line perpendicular to the cable axis. It is formed from a hollow body with an arcuate slope. Furthermore, an opening 41 having substantially the same outline as the engaging piece 37 of the cable outer 34 is disposed in the center of the top plate portion 31 in the axial direction of the cable outer 34, that is, in a direction perpendicular to the engaging piece 37. is perforated. In the control cable fixture configured as described above, the engagement piece 37 and the fixed engagement member 38 are inserted into the opening 41 of the fixed engagement member 38, with the engagement piece 37 aligned with the opening 41, and then the engagement piece 37 is inserted at an angle of 90°. The cable 32 is rotated and engaged so that the engaging piece 37 and the fixed engaging member 38 are perpendicular to each other.
can be fixed to the substrate 13.

Next, the function of this fixture will be explained.

As shown in FIG. 4, when the control lever 8 is rotated horizontally with respect to the board 13 about the fulcrum 25, the inner cable 33 fixed to the rear end of the lever 8 Moves in an arc according to the And this inner cable 33
The cable outer 34 includes an engagement piece 37 of the fitting, and a protrusion 39 of the fitting that is attached to a fixed engagement member 38.
The inner cable 33 can be rotated horizontally (in this specification, this means a plane parallel to the member to which the cable outer 34 is attached, for example, the equipment side base) by sliding within the space 40 of the inner cable 33.
Rotates in the horizontal direction following.

Therefore, since no unreasonable force is applied to the inner cable 33, the lever 8 is not moved and the inner cable 33 is not buckled.

Further, when the lever 8 is rotated, if the inner cable 33 is subjected to movement in both the horizontal and vertical directions due to vibrations of the vehicle or play in the fulcrum 25, the engagement piece 37 performs the above-mentioned pivoting action, and The vibration of the protrusion 39 causes the cable outer 3 to swing in a vertical plane (in this specification, meaning a plane perpendicular to the above-mentioned device side base), so that the cable outer 3 follows the movement of the inner cable 33.
4 swings horizontally and vertically.

At this time, since the fixed engagement member rod 38 is formed on a slope forming a ridge line perpendicular to the cable axis, as described above, it will be able to withstand vibrations of the cable outer 34 in the vertical direction. There is no interference between the cable outer 34 and the fixed engagement member 38.

Therefore, no excessive force is applied to the inner cable 33 as described above. FIG. 6 shows a second embodiment of the present invention.

In this embodiment, the fixed engagement member 38
It is not an integral part of the body, but is a separate hollow body. This separate fixed engagement member 38 is fixed to the substrate 13 by caulking via a holder provided on the fixed engagement member 38. In this embodiment, the height of the space 40 of the engaging member 38 is
Since the height is almost the same as that of the engaging piece 37, the engaging piece 37
The bottom surface of the base seat 36 is arcuate, allowing movement in the horizontal and vertical directions.

Note that if the height of the space 40 here is set higher than the height of the engagement piece 37 and has sufficient swing room, the bottom surface of the base seat 36 does not need to be arcuate.

The other configuration of this embodiment is the same as that of the first embodiment, so the explanation thereof will be omitted.

The operation of this embodiment is similar to that of the first embodiment described above.

As shown in FIG. 5, if the control lever 8 and the fixed engagement member 38 of the cable outer 34 are not on the same plane, a slit 43 is formed at the tip of the pin 42 to prevent the inner cable 33 from coming off. is cut and a bulge 44 is formed. That is, by inserting the ring-shaped tip 45 of the inner cable so as to crush the bulge of the pin 42 inward, the inner cable 33 is prevented from detaching from the pin 42. Further, the cable attachment structure is not limited to the above-mentioned air conditioning cable, but can be applied to any cable that is moored to a swinging lever.

Effects of the invention As is clear from the above explanation, the control cable attachment of the invention allows the cable outer to swing up and down in the vertical direction due to the horizontal rotation of the engagement piece and the rolling movement of the protrusion. Therefore, even if the cable outer is bent or displaced in the horizontal or vertical plane due to the circular arc movement of the control lever, the installation angle of the cable outer will be changed appropriately in response to these movements, and the above-mentioned deflection will be avoided. To achieve light and smooth lever operation by eliminating such problems.
Further, the cable outer can avoid local bending by swinging the engaging piece in the horizontal and vertical planes, and is not damaged.
