If properly adjusted, it can be used critically. Inside the case (1) is made of a material such as stainless steel excellent in corrosion resistance, and the hollow tube-type slide tube (8) having an annular stopper (7) at the rear end is inserted. At this time, the slide tube (8) is secured by the spring (4) between the annular locking jaw (1a) of the upper end of the case (1) to selectively move forward and backward in the case (1) of the slide tube (8) The spring 4, which is a second buffer means held between the locking projection 1a of the case 1 and the stopper 7 of the slide tube, is appropriately distributed by cushioning the load due to external impact. Springs that can act, for example, use high-compression compression springs.

Therefore, the sliding movement in the front-rear direction of the slide tube 8 is performed when an external impact light is applied to the strand 16, and is made by the restoring elastic force by the spring 4. As shown in FIG.

On the front side of the slide tube 8, the above-described strand wire connecting clamp 3 is provided, and has a tapered shape in which the diameter thereof decreases toward the front end of the slide tube 8. Accordingly, the side of the slide tube 8 is formed with a clamping hole 3a of a predetermined size into which the stranded wire 16 can be inserted, and a plurality of internal components for clamping that can clamp the inserted stranded wire 16 therein. The members 9, 10 and 12 are accommodated.

A plurality of projections 9a ', 9b' are formed on the surface to firmly bind the stranded wire. In this case, the plurality of protrusions 9a 'and 9b' are formed to be inclined at an angle in the same direction as the direction in which the strand is inserted, so that the natural line is inserted when the strand is inserted from the front, but in the opposite direction, when the tensile force is applied, the protrusion Do not allow the strands to bind and break away.

The clamping spring 10 is supported by the latching jaw 11 that is bent into the slide tube 8 so that the strand wire binding port 9 is elastically supported forward in the rear of the strand wire binding port 9. A clamping knob 12 is interposed between the stranded wire binding hole 9 and the clamp spring 10.

That is, the clamping knob 12 is supported by the clamp spring 10 at the rear end, and the front side is formed in a tapered shape corresponding to the taper of the slide tube 8, and protrudes upward and downward from the end of the taper. A stand 12a is formed. The protrusion 12a protrudes outward of the slide tube 8 and slides within a predetermined range while being exposed to the outer side of the slide tube 8. To this end, a slide 8a, which is a space in which the protrusion 12a is positioned and slides a predetermined length, is formed on the side of the slide tube 8.

5 is a front view of the buffer clamp according to the second embodiment of the present invention.

As shown in FIG. 5, the buffer clamp 200 according to the second embodiment of the present invention has almost the same technical means provided in the first embodiment of the present invention described above, but the shape thereof is modified. It is. That is, in this embodiment, the clamp 3 to facilitate the connection and disconnection of the stranded wire 16 is provided on the side, and one side is fixed to the shock absorbing spring 18 and the electric pole that causes the buffering effect when an external shock is applied. And at the same time is provided with a control means for adjusting the length.

The basic configuration of the clamp 3 is almost the same as the clamp configuration of the first embodiment described above, but the internal component for clamping in the clamping case 13 which is composed of a closed enclosure having a clamping hole 3a on the side and a rear end thereof is closed. Houses 9, 10, and 12. In addition, a second buffer member such as a spring 4 is mounted between the rear side of the clamping case 13 and the upper portion of the nut 6, but the nut 6 is integrally coupled to the nut 6 through a welding or the like on one side thereof. do.

On the other hand, the nut 6 is screwed so as to move a predetermined distance by the rotation on the spiral portion (2c) of the fixing fastener (2).

6 is a state diagram in which a stranded wire and a cable are installed between pole poles using the buffer clamps 100 and 200 according to the present invention.

As shown in FIG. 6, the cushioning clamps 100 and 200 of the present invention secure the stranded wire 14, on which the communication cable 15 is supported, are fixed on the pole 14 or, if necessary, to adjust separation or tension. As used, it will be described in detail how to use and effects thereof as follows.

First, the shock absorbing clamp 100 is hooked to the fixing member 17 fixed to the upper portion of the pole 14 for temporary cabling of the cable 15 by using the fixing fastener 2 of the shock absorbing clamp 100. And pulling the strand 16 is inserted into the clamp 3 portion of the buffer clamp 100, the insertion method is as follows.

That is, when the end portion of the stranded wire 16 is inserted through the side clamping hole 3a of the clamp 3, the divided stranded wire binding member 9a, 9b provided on the side tapered portion of the slide tube 8 is pushed backward. While the space between the two is enlarged and the center distance between each of the fastener members 9a and 9b enters to the extent that the strands 16 are fitted, the operator can detect the fit state by hand. See 4)

When the insertion of the stranded wire 16 is completed and the hand holding the stranded wire 16 is released, the binding member members 9a and 9b, which have been divided into the rear part by the artificial force, are moved forward by the restoring elastic force of the clamp spring 10. The fastener members 9a and 9b are pushed. In this case, the tapered surfaces of the fastener members 9a and 9b are contracted toward the center along the side tapered surface of the slide tube 8 so that the stranded steel wire 16 clamped to the center portion is firmly fixed. At this time, since the plurality of protrusions 9a 'and 9b' formed at the center of the strand wire binding member 9a and 9b have a step formed rearward, it is possible to more reliably prevent the separation of the strand wire 16 to the front. , When inserted for clamping the strand 16, it is possible to perform a smooth entry. And, the clamp 3 structure of the present invention is a structure that can more effectively prevent the separation after the coupling of the strand wire 16, the strand wire binding member of the present invention as the tensile force is applied in the direction that the strand wire 16 is going to break away 9a and 9b are clamped more firmly by the side taper of the slide tube 8, so that the closed end of the stranded wire 16 once clamped is prevented from being arbitrarily separated unless artificial external force is applied.

When clamping is completed using the buffer clamp 100 at one end of the strand 16, it is necessary to properly adjust the tension of the strand 16, in this case, such as a wrench on the rear end nut 6 of the case (1) When the case 1 is rotated in a forward or reverse direction by combining a tool, the tension of the strand 16 is properly adjusted. This function is possible, and the strand 16 is slide tube inserted into the case 1 so that the slide tube can be slidably inserted. The nut (6) clamped to the side clamp (3) part of (8) and fixed to the rear end of the case (1) is screwed with the male screw (2b) of the fixed fastener (2) hooked to the electric pole (14). As the nut part 6 of the case 1 is rotated, the distance between the fixed fastener 2 and the case 1 is adjusted so that such gap adjustment can eventually adjust the tension of the strand 16.

In addition, when there is a need to separate the strand 16 from the buffer clamp 100 due to communication failure or other reasons, it can be separated by a simple operation as follows. That is, in order to separate the strand wire 16 clamped by the clamp 3 on the side of the slide tube 8, the second buffer member 10 holding the strand wire binding member 9a, 9b is elastically compressed. When switching, the clearance member (9a, 9b) is moved back to the rear tapered portion of the slide tube (8) to generate a clearance to the separation of the strand wire (16) clamped to the binding member (9a, 9b), and eventually The second shock absorbing member 10 only needs to be compressed.

That is, the clamping knob 12 interposed between the fastener members 9a and 9b and the second buffer member 10 has a protrusion 12a protruding outward, which is a slide on the side of the slide tube 8. Since it is exposed on the ball 8a, when the operator grasps the protrusion 12a and slides it backwards, the clamping spring 12 is naturally compressed while the clamping knob 12 slides on the slide tube 8 side, thereby compressing the binding hole ( 9a and 9b may be switched to the unclamped state of the strand 16 as described above.

As described above, the present invention in which connection, tension control, separation, etc. of the stranded wire 16 is extremely easy is performed in the installation and use of the stranded wire 16 from an external shock such as large vehicles in contact with the stranded wire. The protection can eventually prevent damage or cutting of the communication cable 15 which is constructed by a connection creep or the like integrally or separately from the stranded wire.

In addition, when an external impact is applied to the stranded wire 16, first, a tensile force is given to the stranded wire 16, so that a means for buffering it is necessary. In this case, the cushioning clamp 100 of the present invention is provided in the case 1. The slide tube 8 is installed to be elastically slidable by the compression spring 4 which is stored, and the strand wire 16 is clamped using the clamp 3 on the side of the slide tube 8 so that the stranded wire ( 16, the impact applied to the slide tube (8) provided with the clamp (3) through the clamp (3), the end of the slide tube (8) to the inner locking jaw (1a) of the case (1) When the tension is applied and the rear end is elastically supported by the compression spring 4 that is elastically supported by the rear end stopper 7 of the slide tube 8, when the tensile force is applied from the front, the external shock may be slid forward in the case 1. It can be buffered .

Next, when the tensile force due to the external impact is released, it is naturally restored by sliding back from the inside of the case 1 by the restoring elasticity of the spring (4).

In addition, in the second embodiment of the present invention as shown in FIG. 5, the basic operations and effects are the same, and the configuration of the clamp 3 for connecting and disconnecting the stranded wire 16 is similar to that of the first embodiment. Since the same thing, detailed description will be omitted.

If the tension line 16 is to be adjusted, the tension adjustment is made by adjusting the nut 6 screwed to the fixed fastener 2 using a tool such as a wrench in the forward direction. In addition, when the external force is applied to the strand 16 to exert a tensile force, the spring 4 is simultaneously tensioned to prevent breakage or cutting of the strand 16.

That is, the first buffer member 4 in the second embodiment is characterized in that the tension spring is used differently from the first embodiment.

As described in detail above, the present invention is efficient by providing a buffer clamp having a clamp that can be connected more quickly and easily when connecting or disconnecting the stranded wire to the pole in order to install a communication cable, etc. It is also equipped with the tension control function of the stranded wire to facilitate the adjustment work, and by installing a buffer means to prevent breakage or cutting of the stranded wire due to external impact in advance, It can minimize accidents such as communication loss by protecting the system.

In the following claims, there will be disclosed a novel technique that is particularly protected among the technical problems to be solved by the present invention, but various modifications that can be easily changed and implemented by those skilled in the art are the basics thereof. As long as the configuration is the same, it should be considered that they fall within the same scope of the present invention.
