Description

Cable fixing wire {WIRE FOR CABLE FIXING}

The present invention relates to a cable fixture for fixing by connecting a portion of the cable to the hanger of the wire clamp mounted on the telephone pole.

In general, the cable is distributed to each home or office through a cable splitter mounted on a telephone pole or a rooftop. These cables are pulled under tension to prevent sagging and distributed to each home or office. However, as the track is pulled in this way, the cable is often detached from the cable splitter. Therefore, track workers use cable fixtures to prevent the cable from falling off. That is, the cable fasteners prevent the cable from leaving the cable splitter.

In this general cable fixture, as shown in FIG. 1, the hook 12a is caught by the annular hanger 1a of the wire clamp 1 with the cable C held. At this time, the cable (C) is sandwiched and fixed between the inner tube 12 and the outer tube 14 as shown enlarged. Therefore, the cable C is not separated from the cable distributor CD even when the wind pressure is applied. That is, the cable fastener prevents the cable C from being separated from the cable splitter CD.

However, since the cable fixture 10 should be composed of the inner tube 12 and the outer portion 14 as shown in the drawing, the manufacturing cost is excessively increased, and the inner circumferential surface of the outer portion 14 is expanded as shown in the cable (C). ), There is a problem in that it is necessary to form the engaging projection 14b.

In addition, as the cutout portion 14a of the exterior 14 is sharply protruded as shown in enlarged view, there is a problem that the cutout portion 14a penetrates into the operator's hand during the fixing operation of the cable C, causing pain. .

The present invention has been made to solve the conventional problems as described above, and an object thereof is to provide a cable fixing wire made of a steel wire having a structure in which the cable is wound and fixed in a helical form.

In particular, the object is to provide a cable fixing wire consisting of only one unit by a steel wire.

Another object is to provide a cable fixing wire having a mechanism that partially contacts the surface of the cable while in contact with the cable.

Cable fixing wire according to the present invention for achieving the above object, in the cable fixture for fixing a part of the cable by connecting to the ring-shaped hanger of the wire clamp, so that the cable is securely fixed by winding in a twisted state, A helical bar made of steel wire having rigidity, twisted in a helical shape along a longitudinal direction, and having a pitch and an inner diameter by a shape characteristic formed in the helical shape, the pitch and the inner diameter corresponding to the thickness of the cable; Hooks are formed in the end of the helical bar is formed in the same body, bent in a ring shape while forming a ring portion in an overlapped state, and is hooked to the hanger through the gaps of the overlapping portions to be fixed in a locked state; It can be configured to include.

The helical bar may be configured to further include a straight bent portion that is bent in a straight line at an end while supporting the cable in a pressing direction while forming a direction different from the lengthwise direction of the cable. .

In addition, the helical bar may be configured to further include a locking means that is partially caught on the surface of the cable.

The locking means may be configured as, for example, any one of a protrusion formed in an embossed shape or a notch formed in an intaglio shape on the surface of the helical bar.

On the other hand, the helical bar may have a cross section in the form of any one of a circle, a semi-circle, a triangle or a polygon.

Cable fixing wire according to the present invention as described above, because it is composed of a single body by a steel wire is not only easy to manufacture, but also very easy to carry because the weight and volume is very small.

In addition, since the cable is wound around the helical bar in a twisted state, the cable can be easily fixed as well as securely fixed.

In addition, when the locking means is provided, the locking means is partially caught on the surface of the cable, so that the cable can be more firmly fixed to the helical bar.

Hereinafter, a cable fixing wire according to the present invention will be described with reference to the accompanying drawings as follows, the accompanying Figure 2 is a perspective view of the cable fixing wire according to an embodiment of the present invention, Figure 3 is in Figure 2 4 is a perspective view showing a state of use of the wire shown, Figure 4 is a perspective view of a cable fixing wire according to another embodiment of the present invention.

Referring to Figure 2, the cable fixing wire according to an embodiment of the present invention is a helical bar 52 bent in a helical form as shown; It includes; hook 54 is provided in the same body at the end of the helical bar 52.

Helical bar 52 is composed of a wire as shown. The helical bar 52 is wound around the cable (C) in the longitudinal direction as shown in the enlarged view "1" in the drawing. Therefore, the helical bar 52 is preferably configured of a steel wire having rigidity so as not to bend when the cable C is wound. That is, the helical bar 52 is composed of a steel wire bent in a helical shape along the longitudinal direction.

The helical bar 52 has a pitch PT and an inner diameter D as shown in the enlarged views " 2 " and " 3 " The pitch PT and the inner diameter D correspond to the thickness of the cable C to be described later. That is, the pitch PT and the inner diameter D are determined by the thickness of the cable C.

Here, the reason why the pitch (PT) and the inner diameter (D) should be formed corresponding to the thickness of the cable (C) is as follows. If the inner diameter (D) is formed smaller than the thickness of the cable (C), the cable (C) is in close contact with the helical bar 52 because a part of the inner diameter (D) of the helical bar 52 is separated outward Not cold On the contrary, when the inner diameter D is formed larger than the thickness of the cable C, the cable C flows in the inner side of the helical bar 52, that is, the inner diameter D, and thus is wound in close contact with the helical bar 52. Don't. That is, the cable (C) is not fixed in close contact with the helical bar 52 when the inner diameter (D) is too large or too small.

And, if the pitch (PT) is formed too narrow compared to the thickness of the cable (C), the cable (C) is bent at too close intervals along the longitudinal direction of the helical bar 52, so the elastic force is generated while the helical bar ( 52) does not wind smoothly. On the contrary, when the pitch PT is formed too wide for the thickness of the cable C, the cable C is virtually hardly bent and thus cannot be fixed to the helical bar 52 because elastic force is not generated. That is, the cable C is not fixed to the helical bar 52 because the pitch PT is too narrow or too wide to secure the required elastic force. In conclusion, the cable C is firmly fixed to the helical bar 52 by the elastic force generated while winding the helical bar 52 in a twisted state.

Here, it is preferable that the above-mentioned pitch PT is comprised in at least 3 or more so that the cable C may be wound several times in a twisted state. The pitch PT is preferably composed of about three to five. However, the number of pitches PT is determined by the thickness or elasticity of the cable C. That is, the pitch PT is preferably configured in a smaller quantity when the cable C is thick or the elastic force is too strong, and preferably in a larger quantity when the cable C is relatively thin or the elastic force is weak. .

The helical bar 52 may be provided with a straight bent portion (52a) at the end as shown. The bent portion 52a is bent in a direction different from the longitudinal direction of the helical bar 52 while forming a straight line at the end of the helical bar 52. The bent portion 52a serves as a handle of the helical bar 52 while supporting and pressing the cable C as described below.

On the other hand, the hook 54 is formed in the same body at the end of the helical bar 52 as shown. The hook 54 is formed by bending the end of the steel wire constituting the helical bar 52 in a ring shape. That is, the hook 54 is part of the steel wire.

Hook 54 is bent in a ring shape while forming an annular shape with a portion overlapping as shown. That is, the hook 54 is formed by bending the end of the steel wire at least 1.2 to 1.5 times in a round shape. At this time, the hook 54 is bent in an overlapping state while overlapping the end as shown. The hook 54 is fitted to the hanger 1a as described below through the gap between the overlapping portions and is fixed in the locked state.

Referring to FIG. 3, the helical bar 52 is fixed to the wire clamp 1 fixed to the steel wire W through the hook 54 while the cable C is wound as shown. Of course, the helical bar 52 is fixed to the wire clamp 1 as the hook 54 is fitted to the hanger 1a. At this time, the hook 54 is hooked to the hanger 1a through a gap between the overlapped portions.

Here, the cable (C) described above is not separated from the helical bar 52 as it is wound in a twisted state on the helical bar 52 as shown. That is, the cable (C) is formed in the helical bar 52 in a helical shape, and is not separated from the helical bar 52 as the helical bar 52 is wound in a twisted state. In particular, the cable (C) is firmly fixed in a state wound on the helical bar 52 by the elastic force generated while partially bending while forming a twisted state.

On the other hand, the straight bent portion (52a) formed at the end of the helical bar 52 serves to support while pressing the cable (C) at the end of the helical bar 52 as shown. Thus, the cable C is more firmly fixed to the helical bar 52. The bent portion 52a serves as an end side handle of the helical bar 52 when the cable C is wound around the helical bar 52. That is, since the user can fix the cable C to the helical bar 52 while holding the bent portion 52a, the user can easily fix the cable C to the helical bar 52.

On the other hand, as the cable (C) is firmly fixed to the helical bar 52 as shown, even if the wind pressure is not separated from the cable distributor (CD). Of course, the cable (C) is not separated from the cable distributor (CD) as the flow is prevented in a state in which the helical bar 52 is fixed to the wire clamp (1) through the hook 54.

Referring to Figure 4, the cable fixing wire 50 according to another embodiment of the present invention may be provided on the helical bar 52, the catching means that is partially caught on the surface of the cable (C); This locking means is partially caught on the surface of the cable (C) to more firmly secure the cable (C) to the helical bar (52). That is, the cable C is very firmly fixed to the surface of the helical bar 52 by the locking means.

Here, the above-described locking means may be configured, for example, as a projection (PO) formed in an embossed shape on the surface of the helical bar 52, as shown. Such a projection PO can be formed by partially punching (punching with a press die) a steel wire as shown in (a) of the enlarged view "4" in the drawing. The projection PO protrudes to both sides of the steel wire, that is, the helical bar 52, as shown in (b) of the enlarged view "4". Therefore, the projection PO is wedge-fastened to the cable C when the cable C is wound around the helical bar 52. The projections PO may be formed in a quadrangular shape as shown in the drawing. Alternatively, the protrusions PO may be formed in a disc shape or a triangle shape.

Alternatively, the above-described locking means may be configured by notches NC, which are formed in an intaglio shape on the surface of the helical bar 52, for example, as shown in an enlarged view "5" in the drawing. The notch NC may be formed by punching into a press mold not shown in the steel wire before being molded into the helical bar 52. Notch NC may be formed in a triangle as shown, alternatively, may be formed in a semicircle or a quadrangle. Notch NC is preferably formed to a depth of about 0.2 to 0.3 times the thickness (thickness) of the steel wire. This is because, when formed too deep, the rigidity of the steel wire is weakened.

As described above, the notch NC is alternately formed in an alternating state along the longitudinal direction of the helical bar 52 while being horizontal with the longitudinal direction of the helical bar 52, as shown in the enlarged view "⑤". Alternatively, it may be formed along the longitudinal direction of the helical bar 52 as shown in "6".

On the other hand, the helical bar 52 may be formed in a rectangular cross section, for example, as shown in the enlarged view "6". Alternatively, the helical bar 52 may be formed in a cross-section, for example, in the form of a circle, a semicircle, a triangle, or a polygon rather than a rectangle. Of course, the shape of the cross section of the helical bar 52 is determined by the shape of the steel wire. That is, the shape of the cross section of the helical bar 52 is determined by the billet of the wire form. The helical bar 52 is preferably composed of a cross-sectional area, that is, a thickness of about 2mm to 8mm, and is composed of a cross-sectional area (thickness) of about 3mm to 5mm to ensure the required rigidity while easy processing in a helical shape. It is preferable.

The cable fixing wire according to the embodiment of the present invention as described above is not only easy to manufacture, but also easy to carry because the weight and volume is very small because it is composed of a single body by a steel wire.

In addition, since the cable C is wound and fixed to the helical bar 52 in a twisted state, not only the cable C can be easily fixed but also firmly fixed.

In addition, when the locking means is provided, since the locking means is partially caught on the surface of the cable C, the cable C may be more firmly fixed to the helical bar 52.

Since the above embodiments are merely illustrative of preferred embodiments of the present invention, the scope of application of the present invention is not limited to the above, and appropriate modifications are possible within the scope of the same idea. Therefore, since the shape and structure of each component shown in the embodiment of the present invention can be carried out by deformation, it is natural that the modification of the shape and structure belong to the appended claims of the present invention.
