Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for fixing the terminal of an outer casing of a control cable, in which an inner cable is slidably inserted into the outer casing, to a mounting plate that is a fixing member.

Problems to be solved by conventional techniques and ideas Conventionally, in order to fix the terminal of the outer casing of the control cable to the mounting plate, a cylindrical fitting with a thread formed on the outer periphery was fixed to the terminal of the outer casing. A method of inserting it into a mounting hole formed in a plate and fixing it to the mounting plate with a nut screwed into the screw.
Alternatively, a cylindrical fitting with a locking groove and a collar formed on the outer periphery at the end of the outer casing is inserted into a mounting hole formed in the mounting plate, and the collar is brought into contact with the rear surface of the mounting plate, and the locking groove has elasticity. The commonly used method is to insert a clip and clamp the mounting plate between the flange and fix it. Although the method of fixing with a nut is strong, it takes time to work, and the method of fixing with a clip is Although the work is simple, there is a risk that the clip may come off due to vibrations, etc., and there is also a drawback that rotation of the outer casing around the axis cannot be prevented.

Means for Solving the Problems The present invention, as a means for solving such problems, has a part formed on a part of the outer periphery of the fitting part that fits into the mounting hole formed in the mounting plate. A tube that has a hook part that projects from the front surface of the mounting plate through a relief groove, and a collar with a gap corresponding to the thickness of the mounting plate formed between the hook part and the hook part. A mounting plate is fixed to the end of the outer casing, and the fitting part of the cylindrical fitting is inserted into the mounting hole and rotated at a predetermined angle around the axis, thereby attaching the mounting plate between the collar and the hook part. In addition to having a configuration in which it is mounted so that it cannot be moved back and forth by being pinched, a locking hole is provided at a position that corresponds to the relief groove of the collar, and a pawl piece is inserted into the locking hole and engaged with the relief groove. It is configured so that it cannot be rotated.

Functions and Effects of the Invention The present invention has the above-mentioned structure, and by simply aligning the hooking part of the cylindrical fixture with the relief groove, fitting the fitting part into the mounting hole, and rotating it by a predetermined angle around the axis, the flange can be removed. The cylindrical mount is mounted so that it cannot move back and forth with the mounting plate sandwiched between the holder and the latching part.Next, when the claw piece is inserted into the locking hole of the collar, the claw piece engages with the escape groove. It is fixed in an unfixable manner around the axis, making it extremely easy to work with, and the cylindrical fixture will not rotate unless the claw piece comes off, so there is no risk of it falling out of the mounting hole. Since it does not cause eyelids and does not rotate around the axis, it has the effect of keeping the wiring direction constant when a curved guide tube is fitted to the outer casing and the cable is routed in one direction. .

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a push-pull control cable, in which a strand 5 is formed by spirally winding a large number of thin steel wires around the outer periphery of a liner 4 made of synthetic resin, and the strand 5 is covered with a jacket 6 made of synthetic resin. An inner cable 2 made of a large number of fine steel wires twisted together is inserted freely into the outer casing 1, and the jacket 6 at the tip of the outer casing 1 is cut off to expose the strand 5. A steel cylindrical body 7 having a groove 8 is fixed by caulking, and a synthetic resin cylindrical fitting 9 is integrally fixed to the outside by insert molding.

This cylindrical fixture 9 includes, in order from the rear side to the front side, a base 10 that wraps around the cylindrical body 7 and is fitted to the tip of the outer casing 1, a large-diameter collar 11, a fitting part 12, and a narrow neck part. 13 and the guide part 14, and the rear surface of the collar 11 has two parts facing the base part 10.
Two ribs 15 are formed, and an arc-shaped locking hole 16 is transparently provided near the outer periphery of the collar 11 between the two ribs 15.
Hook parts 17, 17 are formed at positions corresponding to 15 with a small distance between them and the collar 11, and an inner cable 2 is formed at the center of the insertion part 12 and the narrow neck part 13.
The insertion hole 18 through which the guide portion 1 is inserted almost tightly
A guide hole 19 is formed in the center of the inner cable 2. A guide hole 19 is formed in the center of the rod 20, into which the tip of the inner cable 2 is fitted into a blind hole 21 formed at the rear end, and the rear portion of the rod 20, which is connected by caulking, is fitted tightly and freely. .

The cylindrical fixture 9 having the above structure has a mounting plate 26 attached to a bracket 25 which is a fixed mating member.
Mounting hole 27 with relief grooves 28, 28 formed on the top and bottom
2, align the catch parts 17, 17 with the relief grooves 28, 28, fit the fitting part 12 tightly, and as shown in FIG. Rotate 90 degrees while touching the rear surface of 26, and remove the tsuba 1.
After the mounting plate 26 is sandwiched between the mounting plate 1 and the hooking parts 17, 17 and fixed so as not to be movable in the front and rear direction and the radial direction,
An arc-shaped claw piece 30 made of synthetic resin whose tip width can be elastically contracted by the split grooves 31, 31 is inserted from the rear side into the locking hole 16 of the collar 11, and the protrusions 32 on both sides are inserted.
32 on both sides of the locking hole 16, the tip of the claw piece 30 passes through the upper relief groove 28 and is fixed to the collar 11 in an unmovable manner, thereby preventing the claw piece 30 from engaging with the relief groove 28. Depending on the case, the cylindrical fixture 9 is fixed in a non-rotatable manner, and the lever 2, which is a movable member, is attached to the center part 22 formed at the tip of the rod 20.
4 are connected by a pin 23, and on the driving side, the rod 20 is moved into the guide hole 1 by swinging a lever 24.
9, the operating force is transmitted to the inner cable 2, and on the drive side, the rod 20 slides in the guide hole 19 due to the sliding of the inner cable 2, and the lever 24 swings. On either side, as the tip end of the rod 20 swings up and down due to the swinging of the lever 24, the guide section 14 swings due to the bending of the narrow neck section 13.
