Etc., and the main body parts 111 and 121 are held inside them.

Conventionally, in order to fix and hold the cable 2 to the receiving members 11, 12, for example, the receiving member 11, as shown in FIG. 14, a braid 3 having low water absorbability and elasticity is used. The receiving object 11 and the cable 2 placed on the receiving surface 111c of the receiving object 11 were bound.

[Problems to be solved by the invention] When the cable is fixedly held on the receiving object by using the braid as described above, the main body of the receiving object is wedge-shaped,
If the position shifts toward the tip even by a small amount due to shock such as vibration, the force for fixing and holding the receiving object and the cable easily decreases together with the decrease in the frictional force generated by the binding.
There was a risk that the cable could be dropped from the hardware. For this reason, it is necessary to wrap the braided cord strongly and repeatedly between the metal fitting and the cable, and careful work is required, so that the work takes a long time. Further, in such a case, unless the user is skilled, the fixing and holding force varies for each work, and it is difficult to stably fix and hold the cable on the receiving object.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a cable tying tool capable of stably fixing and holding a cable on a receiving object with good workability and without individual difference or work difference. To do.

[Means for Solving the Problems] A cable restraint device of the present invention is a flange shape that is fixed to a wall or the like and that projects to the back surface side of the receiving surface orthogonal to the receiving surface where the cable is fixed and held. A cable restraint for fixing and holding the cable to a receiving object having a side end of the receiving end, the two engaging grooves provided at predetermined intervals into which both end parts of the receiving object are fitted. And a base having two band locking portions provided adjacent to the outside of each of the engaging grooves, and the base locking portions mounted on the respective band locking portions of the base and placed on the receiving surface. It is characterized in that it is composed of two bands for binding the cable.

[Operation] In the cable binding device of the present invention, the base is pushed up from the lower side of the receiving object, and the engaging grooves of the base are inserted into both end portions of the receiving object to attach the base to the lower side of the receiving object.
And, the cables placed on the receiving surface of the receiving object are pressed against the receiving surface to be bound by the bands attached to the band locking portions of the base. Thus, in the cable tying device of the present invention, the cable is fixedly held on the receiving object by the frictional force of the base and the band.

Embodiments Embodiments embodying the present invention will be described below with reference to the drawings. The cable tying device of the present embodiment is the tenth to twelfth.
The cable 2 is fixedly held on the receiving member 12 illustrated in the figure.

As shown in FIG. 1, this cable tying device is composed of a base 5 made of an ABS resin and a holding portion 51 and a movement preventing member 52, and two bands 6 made of nylon 66. There is.

The sandwiching portion 51 that constitutes the base 5 includes a bottom portion 510, a wall portion 511 that is integrally formed with the bottom portion 510 and obliquely rises from both sides, and has upper end sides formed vertically. 6 pieces of protrusions 512 that vertically project vertically
And a band locking portion 513 that integrally extends in a wing shape from the outside of the upper end of the vertical portion of the wall portion 511. An opening 510a for inserting the movement preventing member 52 is formed in the center of the bottom portion 510. The protrusions 512 and the vertical portions of the respective wall portions 511 facing each other are engaged with each other at predetermined intervals and are parallel to each other in the engagement grooves 514.
Is formed. These engagement grooves 514 are formed so that the side of each wall portion 511 of each protrusion 512 is slightly thicker than the tip side, and three minute projections are formed in the vertical portion of each wall portion 511 toward the protrusion 512. Since each of the portions 515 is formed, the width is slightly smaller than the thickness of the side end portion 121d of the receiving member 12 (see FIGS. 10 to 12). Each band locking portion 513 has a second
As shown in the figure, the upper stage, which is formed in two stages, has an upper face as a contact face 513a having a low cross-section circular arc shape at the center, and has two insertion holes 513b parallel to each other. The lower stage is formed by two parallel support rods 513c, and the gap between the upper stage and the lower stage is one insertion hole 513d. These two insertion holes 513b and one insertion hole 513d are formed in parallel with the engagement groove 514.

A movement prevention member 52 that constitutes the base 5 together with the holding portion 51.
As shown in FIG. 1, an upper part 520, a wall part 521 that vertically descends from both sides integrally with the upper part 520, and a rib 522 fixed to the inner surface of each wall part 521. Two pieces of protrusions 521a are formed at the lower end of each wall 521 so as to protrude away from each other, and a fixing groove 52a is formed between the protrusions 521a. The rib 522 has a notch formed at the lower end, so that each wall portion 521 can be bent and the fixing groove 52a can be engaged with the opening 510a of the holding portion 51.

As band 6, the one described in Japanese Utility Model Publication No. 50-1503 is adopted. The band 6 has innumerable notches 61 extending in the width direction on one surface, and has a fixing hole 62 at one end that engages with the notch 61 at a predetermined position.

The cable tying tool of the present embodiment fixes and holds the cable 2 on the receiving member 12 as follows. First, as shown in FIG. 2, the band 6 corresponding to the outer diameter of the cable 2 is passed through the insertion hole 513d of the holding portion 51 of the base 5 with the notch 61 facing upward. Then, the holding portion 51 is brought under the receiving object 12 on which the cable 2 is placed so that the fixing hole 62 of the band 6 is on the front end side of the receiving object 12. Then, push up the sandwiching portion 51 from below,
As shown in FIG. 3, the engaging grooves 514 of the sandwiching portion 51 are fitted into both side end portions 121 d of the socket 12 to attach the sandwiching portion 51 to the lower side of the socket 12. At this time, the cable 2 comes into contact with the contact surface 513a of the band locking portion 513 of the holding portion 51. Next, the fixing groove 52a of the movement preventing member 52 is engaged with the opening 510a from the back surface side of the holding portion 51. At this time, the movement preventing member 52 is
Through the through hole 121e at the predetermined position of the receiving object 12,
520 contacts the back surface of the receiving surface 121c of the receiving member 12. Subsequently, as shown in FIG. 4, the band 6 is wrapped around the cable 2, and the tip of the band 6 is passed through the fixing hole 62 and tightened to cut off the excess tip portion. At this time, the band 6 is hung at a right angle to the cable 2, and the notch 61 is tightly attached to the outer surface of the cable 2 without a gap. Therefore, the receiving surface 121c of the receiving object 12
The cable 2 placed at 1 is pressed against the receiving surface 121c by the band 6, and is fixedly held by the frictional force between the contact surface 513a and the band 6.

Thus, in the cable tying tool of this embodiment,
The cable 2 can be easily fixed and held on the cable 12 with good workability without any individual difference or work difference.

When the receiving member having no through hole shown in FIGS. 7 to 9 is used, the cable 2 is fixedly held by the holding portion 51 not equipped with the movement preventing member 52, as shown in FIG. be able to.

When the diameter of the cable 2 is small, the band 6 is passed through the insertion hole 513b of the holding portion 51 as shown in FIG. As a result, the area of contact between the cable 2 and the contact surface 513a can be reduced, so that the contact area between the band 6 and the cable 2 is increased, the frictional force due to the notch 61 of the band 6 is increased, and a stable fixing and holding force is obtained. Obtainable.

In addition to the above effects, in this cable tying device, the detachable movement preventing member 52 can prevent the cable 2 from moving toward the tip of the receiving member 12 due to vibration or the like.

Further, in this cable tying tool, since the engaging groove 514 is formed to have a width slightly smaller than the thickness of the side end portion 121d of the receiving object 12, the base 5 before the band 6 is attached is the receiving object 12.
It can be prevented from falling off by frictional force.

Furthermore, in this cable tying tool, each band locking part 51
Since 3 has a plurality of insertion holes 513b and 513d, the band 6 can be inserted according to the diameter of the cable 2, and
The frictional force can prevent the band 6 from falling off the base 5.

In addition, with this cable tying tool, the contact surface with an arcuate cross section
Since it has 513a, movement of the cable 2 in the width direction can be prevented.

In addition, in this cable tying tool, the wall part 511 bends so that the base 12 can be clamped so that the base 5 does not fall off from the base 12, and the intervals of the engagement grooves 514 can be freely selected. can do.

Furthermore, in this cable tying tool, since the engaging groove 514 is formed by the six projecting portions 512, the gaps between the respective projecting portions 512 are peeled off and dimensional errors due to sink marks during molding can be prevented. it can.

In the cable tying device of the present invention, various bands can be adopted as long as they are attached to the band locking portions of the base and tie the cables placed on the receiving surface. In the cable tying device of the embodiment,
Since the band 6 described in the publication is adopted, the cable 2 can be obtained by simply passing the tip of the band 6 through the fixing hole 62 and tightening.
It is possible to complete the binding between the work and the receiving object 12, and it is possible to greatly reduce the variation between the work and the individual by a simple work and a small tightening force. However, band 6
If the cable 2 is not fixedly held on the receiving object 12 using only the band 6, it is necessary to hang the band 6 as shown in FIG. 13, and the surface of the band 6 having the notch 61 is entirely covered with the cable 2. It is difficult to make close contact with the outer surface of the without gap. For this reason, it is difficult for the band 6 alone to exert a sufficient frictional force between the band 6 and the cable 2, and the bracket 12
Therefore, the cable 2 cannot be stably fixed and held.
However, when the cable tying tool of the embodiment is used, the band 6 is hung on the cable 2 at a right angle, and the frictional force is stabilized, so that the fixing and holding force for the cable 2 is unlikely to vary.

[Effects of the Invention] As described in detail above, the cable binding device of the present invention is provided adjacent to the outside of each of the two engaging grooves into which both side ends of the receiving member are fitted. It is composed of a base having two band locking parts formed therein and two bands attached to the band locking parts of the base and binding the cable placed on the receiving surface. Therefore, the following effects can be obtained by using this cable tying tool.

Careful work is not required and the work can be completed in a short time.

Further, even if not an expert, the fixed holding force for each work is stable, and the cable is not dropped even when a shock such as vibration is applied to the receiving object or the cable.
