Description

Electric cable connect bar for an electric pole

.

[Technical field to which the invention belongs and prior art of the field]

The present invention relates to a light steel pole for a telephone pole, and solves the problems arising from the conventional hard steel light steel as a metal material is not used, that is, a short durability due to heavy weight and corrosion, and a high frequency of electric shock accidents. It is related to the advanced concept of Gyeongwangeum for telegraph poles.

Therefore, if you look at Patent No. 10-1337685 invented and registered by the present inventor among the prior patent documents for the conventional light-barreled light that can replace steel light-walled metal, the insulator fixing bracket is fastened to the FRP body in the form of a square tube. A hole through which the rod body is penetrated instead of a method of fixing the FRP body and the FRP body with screws after forming a hole for penetrating the rod body and passing the rod body through the hole, and fixing the FRP body and the rod body with a screw. Another hole is drilled in the direction perpendicular to the FRP body, and then a drill is inserted into the hole drilled in the direction perpendicular to the hole through which the bar body is penetrated to form a hole in the rod body. Then, a pin is inserted to the rod body and the FRP. The bar has a structure in which the body is united, which is predicted that the strength of the wire connecting rod may be somewhat insufficient compared to the present invention.

And if you look at Patent No. 10-1061655 invented and registered by the present inventor, the FRP body is divided into an upper body and a lower body, and the upper body and the lower body must be assembled through bolts and nuts. There is a disadvantage that the strength of the FRP body is insufficient.

In addition, if you look at Patent No. 10-1894186, which is the inventor of the present invention, in Patent No. 10-1337685, one of the three bars to which the insulator fixing bracket is fastened is replaced with a long bar, As described above, the method of intersecting the hole for fixing the rod body and the FRP body by inserting a pin and a hole into the FRP body to fix the rod body with a pin is the same. This is compared with the present invention. It was predicted that the strength may be somewhat insufficient.

It is provided with a fixing pin 30 to fix.

In Example 2 as described above, the strength of the FRP body was further reinforced by reducing the number of square holes formed in the FRP body compared to the example of Example 1, and the strength of the wire connecting rod was reduced as the number of support legs of the wire connecting rod was also reduced. In addition, it is better, and in particular, the structure of the wire connecting rod 25 is further reinforced as shown in the drawing compared to the above-described patent registered with the present inventor, thereby increasing durability.

Next, looking at Example 3 of the present invention, the structure can be clearly seen through Figs. 7, 8, and 9, and as shown in the drawing, the FRP body 40 in the form of a square tube through an extruder made of FRP as a material After extruding, cut to a certain length and drill the through hole 47 of the power pole fastening bracket through which the fastening bracket for fixing the FRP body 40 to the power pole is drilled into the center of the FRP body 40 as shown in the drawing. The first square hole 41, the second square hole 42, and the third square hole 43, through which the support legs of the wire connecting rod pass, are horizontally formed on the left and right of the fastening bracket through hole 47, and the first square hole The opposite side of the hole 41, the second square hole 42, and the third square hole 43, that is, the first square hole 41 and the second square hole 42 in the FRP body 40, based on FIG. ) And the rear of the third square hole 43, the first hole 44, the second hole 45, and the third hole 46, through which the threaded rod of the electric wire connecting rod passes, are the first square hole 41 and the second hole. It is formed concentrically with the square hole 42 and the third square hole 43.

Subsequently, with the reinforcing plate 51 as the center, a support leg 52 penetrating into the first square hole 41 and the second square hole 42 and the third square hole 43 of the FRP body 40 is on one side. The support leg 52 is provided with a screw rod 53 penetrating into the first hole 44, the second hole 45 and the third hole 46 of the FRP body 40, respectively, and the support leg On the opposite side of 52 is provided with a wire connecting rod 50 in which a hole 55 is formed through which the wire fastening fixture fixing pin passes.

Next, through the first hole 44, the second hole 45 and the third hole 46 of the FRP body 40, it is assembled to the threaded rod 53 of the exposed wire connector 50, and the FRP body A nut 60 for fixing 40 and the support leg 52 to be integrated is provided.

In Example 3 as described above, compared to the examples of Examples 1 and 2, the fixing pin for fixing the wire connecting rod and the FRP body was not used, and as shown in the drawing, the nut ( 60) is assembled so that the support leg 52 and the FRP body 40 are integrally formed, and the number of holes formed in the FRP body 40 is the least, so the strength of the FRP body 40 is also the best. As in Example 1 and Example 2, the structure of the wire connection rod 50 is more economical and workability is improved because the fixing pin for fixing the wire connection rod and the FRP body is not used. As shown in the figure, with the advantage of being further reinforced to increase the durability, the replacement of the wire connecting rod 50 from the FRP body 40 is very easy.

In the above three embodiments, a blocking plate may be fixed to the left and right ends of the FRP body with an adhesive to prevent dust, rainwater, insects, small birds, etc. from entering the FRP body, but the blocking plate is a practical method of the present invention. There is no direct connection to the composition.

The present invention as described above increases the durability as the structure of the wire connecting rod or the structure of the FRP body is reinforced more sturdily compared to the pre-registered electric pole gyeongwangeum of the inventor of the present patent application, and in the case of Example 3, With the effect of increasing the durability, it is very easy to replace the wire connecting rod from the FRP body.
